And, nowadays, there are cheap chips with MMU, many of them supported by VxWorks 5.x. But, for many of these microprocessors, an OS with only "threads" instead of "processes" is usually more fast in task switching activities. --------------------------- Newsgroups: comp.os.vxworks Subject: Re: VxWorks Vs other embedded OSs Date: 30 Apr 2002 14:59:43 -0400 From: Bill Pringlemeir Organization: Factory of the mind Message-ID: References: <1cdb3add.0204291306.2f4ebd6c@posting.google.com> <74c2e5b4.0204300849.17877357@posting.google.com> Sender: bpringlemeir@DeadDuck Srivathsa wrote in message <1cdb3add.0204291306.2f4ebd6c@posting.google.com>... >> Hi, I am new to embedded OS' Just want to know how VxWorks >> compares against other embedded OS'. >> 1) Psos seems to be as popular as VxWorks.

Any examples from the real world? The answer is, "what ever embedded app can afford it". MMU's are quickly becoming common on all RTOS candidate CPUs. This is because as clock speeds increase, you must cache memory and an MMU is necessary to mark memory sections as cacheable, writeable, etc. You have alluded to a performance hit. This is certainly true in many cases. You also wouldn't want to have virtual memory (VM) on an embedded app. However, because previous routers haven't had a heavy process model, don't suspect that future routers will not. The separation of processes via memory protection provides a layer of protection/debugging that can aid development of a large project. Also, depending on the CPU, a process switch might be as fast or faster than an RTOS switch depending on register banking, etc. Certainly an MMU can allow greater control of memory and hence cache effects. Routers will continue to expand on functionality and at some point they may convert to a system that uses memory protection. So embedded apps would use a `process model' if the cost was little or none.

I am aware of Hwa Jin Bae's vxmalloc.c, which is partially based on Doug Lea's malloc.c and am aware of suggestions on the FAQ sites: http://www.xs4all.nl/~borkhuis/vxworks/vxw_pt6.html#6.2 Based on suggestions in WRS's application note on heap management: http://web1.windriver.com/windsurf/appnotes/ide/tornado/t2/APN116/appnote116 .pdf the cleanest solution seems to be to use the memPart* subroutines and layer a malloc library on top of them. From there it would be easy to install a malloc library with built-in monitoring or merge in something like Walter Bright's mem package. Keep in mind that I need to have a solution that is portable (one that would work on PPC and othe target architectures in addition to SPARCSIM and SIMPC) and that completely replaces the C language free / malloc interface (compile time macro swizzling is not an option since we don't have source to all the components we use). On a Tornado 2.02 system (W2K / vxsimpc), I see that memPartLib.o embeds definitions for malloc and free: [C:/Tornado/target/lib] ../../host/x86-win32/bin/nmsimpc.exe --defined memPartLib.o 00000000 b .bss 00000000 d .data 00000000 t .text 00000000 t ___gnu_compiled_c 000009e8 T _free 000009d4 T _malloc 000009bc T _memAddToPool 0000089c t _memAlignedBlockSplit 00000018 D _memDefaultAlignment 00000190 T _memPartAddToPool ...

The component (the .cdf) describes the object module that's needed. Then, when you switch to the VxWorks tab, it "verifies" the environment by checking the library against the components.

There are ways. You can use a binary editor to change the name from _malloc to something like _xyzloc in the library file. You can then supply your own implementation of those functions. Objcopy allows you to rename symbols; extract the .o, rename _malloc and _free and add it back to the archive. Or, you could ask your WRS FAE for the source to memPartLib.

I wasn't going to enter this discussion, but since it seems to have concluded that VxWorks AE is a process model, and therefore has poor performance, I thought I'd add some comments. 1) VxWorks AE protection domains are not the same as processes, at least not in the Unix/Windows sense of the word. They are passive containers, not schedulable entities. VxWorks AE still schedules at the task level. 2) A process model does not have to mean poor performance context switching. It is often down to smart management of the context information, and correct usage of the MMU's address space support features. Task context switches on most CPUs are unaffected by the addition of protection domains. How? By utilising features in the MMU designed to support a full process model, it is possible to avoid doing any more work on context switches for most CPUs. The exception is the case where the cache is indexed by virtual address, and offers no other tricks to optimise the process. In those cases, some context switches will require a cache flush. > I have seen a few PRETTY BIG APPLICATIONs (by my experience): routers. > And they are all based on OS's that dont use the process model. Indeed, many internet infrastructure devices can be built very successfully with VxWorks 5.x. I guarantee that by the time you read this message it will have passed through at least one box running VxWorks 5.x. The core functionality of these devices may well make more sense in the kernel for absolute performance (especially if it is processing every packet). But what about that web server used for configuration purposes?

The path C:\test is very unlikely to be something that VxWorks will use. Don't be fooled by the fact that the Tornado WindSh shell sees files that way - it is a host based shell that uses the host file system. In this case, the compiler will be turning \t into a tab character as well, which is almost certainly not what you intended... > httpRpmConfAdd (HTTP_M_POST, "/fileset", httpRpmUpload); > > > When I upload a file through IE browser but it will appear error message : > Data abort > Exception address: 0x00000004 > Current Processor Status Register: 0x20000013 > Task: 0xf4ce28 "tHTTPd" > > Please give me some advice !! First, you should get a stack trace from the task that crashed (see the tt function). It may not work though since the exception address was down near zero, but it is worth a shot.

These teams need different configurations, (e.g.: some use T2CP4, some use T2CP3, some use DosFS2, some don't, etc.) and it's very difficult to have everybody in a team use the same configuration. What I want to do is to put these different Tornado tree configurations under version control, so that a user could check out the appropriate Tornado tree. For that reason, I've been following the T2/PVCS threads, and it appears that this is feasible, and in fact recommended. I've pasted a paragraph about this under here. My question is the following: I'm not fully clear on "you have to run the Tornado installer after extracting the complete tree...". Can someone clarify this for me? From what I understand, installing a tree from the distribution CD is what the installer does. So, once I've restored a Tornado tree, and adjusted the contents of the torVars.bat file, how exactly would I "run the Tornado installer" so as to obtain a working Tornado installation? Thanks!

This version definitely runs on very low performance CPUs. The other thing is VxWorks AE, which has pretty much the same API, but supports for a process model.

Could you explain exactly what you are trying to do? If you include the right header files, vxWorks will compile OK. You don't have an intrinsic need for such a definition, but you can make one up yourself. As to your question about variations, they are not allowed. You have to decide exactly what you want and why.

There are quite a few differences. Well, I meant, my code should work for a target (Tornado 2) and simulation (Windows NT) environment, so I use defines to make sure the comipler understands environment specific code. e.g. Tornado understands when I say: sysClkRateGet(); NT does not. So: #ifndef _WIN32 long l_TicksPerSecond = sysClkRateGet(); #else long l_TicksPerSecond = 500; #endif But this does not satisfy me. So I want to know, is there another define for VxWorks, so I can be more specific than #ifndef _WIN32 ??

You can use whatever you wish, within reason. vxWorks itself does not have any #defines in the header files like that. There is a #define VX_READ in vxWorks.h that would work if you are not using that header in the simulator. I would make up something, like #define TARGET_XXX where XXX is something that you would recognize. There is nothing inherent that will always work.

WindRiver is now full of ex-ISI and otherwise incompetent people, so do not regard a TSE's answer seriously, just get him to escalate this TSR to Engineering. I can assure you that all current and past versions of VxWorks will honor Mutex state between any two tasks, i.e. there is no different how Mutex works if the tasks where same or different priority. Whatever is the state of the documentation (i.e. format product requirements), if for some reason the Mutex gets broken, e.g. for equal-riority tasks, the product will fail standard QA tests. A lot of higher layer VxWorks code relies on Mutexes, so the test coverage for this module is plenty. On many architectures, the lowest level primitives including binary and mutex semaphores, are re-written in native assembly language, to precisely immitate the portable "C" version of the same code.

I don't think that there was a clear intent to have the scheduling of the same priority tasks one way or the other. Yet, I think it is useful to have a task finish the work before allowing another task (of same priority) to take over. How about proposing a new task option bit that can be set? Also, I would use mutex anyway for all shared resources. You can depend on all the tasks accessing the resource to be the same priority tasks. But things can change... especially when system gets very big and other engineers take over the work. I think it is a good practice to defensively program against future misunderstandings. It doesn't always work... :-) - -- Hwa Jin Bae mailto:hjb@pso.com http://www.pso.com --------------------------- Newsgroups: comp.os.vxworks Subject: WindRiver VisionEvent Setup Date: Wed, 01 May 2002 12:57:42 -0400 From: Babu Yama Organization: Lucent Technologies Message-ID: <3CD01E86.D8BF08BB@lucent.com> Hi, Any body has any good experience in setting up WindRiver VisionEvent?

But there is nothing stopping you from making your own, e.g. you could put in a specific #define of your own choosing at compile time. (For Tornado 2, select 'builds' in the workspace, then click on the build you want to change and then click on the C/C++ tab and put the macro you want at the end of the window.

The implementor of a priority based pre-emptive scheduler clearly has to make a decision when handling tasks of the same priority. If a task becomes ready, should it be placed at the head of the queue or tail of the queue of tasks with the same priority? Normally, and this is the case for the Wind kernel, the task would be placed at the end of the list. That seems the most logical, especially when people use the phrase "run to completion" to describe the scheduling algorithm (though, one should note, that phrase is not its official name). Will it change in VxWorks? Unlikely. If it isn't broken, why fix it? Should you rely on priority for mutual exclusion? No. There are a number of primitives in all real-time operating systems for ensuring mutual exclusion; use one of them and you'll be safe for the future. For VxWorks, you have the following choices: 1) Mutex semaphores (see semMLib) 2) Pre-emption locking (see taskLock() & taskUnlock()) 3) Interrupt locking (see intLock() & intUnlock()) Which should you use? Depends on your application. From what you have written, I would suspect that (1) or (2) would be the best fit for what you are doing; if you are concerned about semaphores (?), perhaps (2) is something you should look at. I often use a trick here to "hide" the exact implementation here. Define LOCK() and UNLOCK() macros to surround your code with. That way you have the choice of anything from defining them to be nothing, using a semaphore, or using taskLock(). If you think you'll need intLock() ever, you need handle a return from LOCK() and pass it to UNLOCK() though, so think carefully about that one! As for the answer you got from Wind River support; it would seem to be sensible to me. There is no guarantee given - I just checked in manuals, and nowhere that I could see is the behaviour you have described documented. Since that is the case, I would be cautious relying on it if moving to new versions of VxWorks was something I thought I might do. Now, you might decide that the risk is low enough, and the benefit in your application outweighs that risk. If you do come to that conclusion though, I'd make sure the places in the code where this assumption was used were clearly marked (or use the macro trick I described above), just in case... The same applies when using "undocumented" features in Windows, or any other operating system, library etc. HTH, John... > How many of you are avoiding the use of semaphores for protecting global > variables because you think vxworks will schedule (with timeslicing > disabled) same-priority tasks to always run to completion until they > voluntarily give up context? > > I came across this design technique when reviewing a project in my > company, and submitted a TSR to ask Windriver about it.

You cannot use the RAM disk directly from the Tornado shell since that is a host based tool, and your file system is on the target. You can add the target based shell if you like, or you can use the '@' prefix to the commands like cd that exist on both (assuming you have the FS shell command utilities on the target - if you don't, then use ioDefPathSet() instead of cd). If you want to copy files to the RAM disk from the host, then you'll need to add the file system utilities to the target. I'd suggest adding the target tools (shell, loader etc) as it will all behave more logically if you are actually working from the target rather than via a host based tool when trying to copy files.

I read the question as referring to Mutex semaphores behaviour on tasks of the sam epiroority, while others beleive that Michael is trying to rely solely on priority for protecting global resources. Michael, priority is a very TEMPORARY attribute of a task, you specify one priority at task intialization, but the task calls subroutines from libraries using Mutex semaphores, which can invert priorities. Also, at later project stages (code reuse) the system engineer can change the initial relative priority of tasks too. Dont take shortcuts, use Mutex samaphores for mutual exclusion.

" sendto: S_errno_ENOBUFS " RESOLUTION: SECTION I : - - - - ENOBUFS occurs mostly because the network stack is running of mbufs: Here are some instances where it is more likely to appear: 1) From setsockopt() setsockopt needs a cluster of size 128 bytes to store the socket options and the ENOBUFS error may indicate that no 128-byte clusters exist. SOLUTION : increase the value of CL_SIZE_128 in ../target/h/netBufLib.h 2) From route_output() The ENOBUFS error may occur when there is a write operation to a routing socket and: a) a mbuf is not available OR b) where the data in the first mbuf is less then the minimum protocol header and it tries to check the second mbuf and try to arrange all the headers in the first mbuf with a call to m_pullup() and this one may need some additional mbufs which are not available. SOLUTION: increase the mbufs(in general) SEE SECTION II 3) From tcp_input() when tcp_template() fails because it can't create a skeletal tcp/ip header because mbufs are not available: SOLUTION : increase the mbufs(in general) SEE SECTION II 4) From tcp_output() when it can't allocate enough mbufs for IP and TCP headers SOLUTION : increase the mbufs(in general) SEE SECTION II 5) From tcp_usrreq() When it is unable to create tcp_template() because it is running out of mbufs which are supposed to be used for transmissions on a particular socket connection. At this stage it starts keepalive timer, create output sequence space and send initial segment on connection. SOLUTION : increase the mbufs(in general) SEE SECTION II 6) From sosend() When it can't find a cluster of hte required size to place the data that has to be sent. SOLUTION : increase the mbufs(in general) SEE SECTION II 7) From sosetopt() When SO_SNDBUF and SO_RCVBUF are full. SOLUTION: increase the size of the SO_SNDBUF /SO_RCVBUF in ../target/h/sys/socket.h 8) From in_pcballoc() When a pcbstructure cannot be malloc'ed because of no mbufs SOLUTION: increase the mbufs(in general) SEE SECTION II 9) From in_control() When a MALLOC fails because of no mbufs while the interface specific fields are filled in by proper SIOCSIF... Calls. SOLUTION : increase the mbufs(in general) SEE SECTION II 10) From rttequest() When there is no mbuf when a routing entry has to be created. SOLUTION : increase the mbufs(in general) SEE SECTION II 11) From raw_attach() When there are no mbufs while trying to allocate a control block and some buffer space for the socket. SOLUTION : increase the mbufs(in general) SEE SECTION II 12) From add_lgrp() When it runs out of mbufs while trying to add an IP to a multicast group. SOLUTION : increase the mbufs(in general) SEE SECTION II 13) From ip_output() When it tries to copy data from the segment and makes a header and try to link in the form of mbuf chain and runs out of mbufs. SOLUTION: ipstatShow() whill increment the drops++. increase the mbufs(in general) SEE SECTION II 14) From ip_setmoptions() a)When a setsockopt is issued by an user with multicast options And there is no multicast option buffer attached to the pcb then an attempt will be made to allocate one. It may fail because of lack of mbufs: b) If it can't allocate a new multicast record when a new Address comes in because of no mbufs. SOLUTION : increase the mbufs(in general) SEE SECTION II 15) From ipOutput() /* in case of END drivers only */ a) If muxAddressForm cannot allocate link level header because of no mbufs we get this error: SOLUTION : increase the mbufs(in general) SEE SECTION II b) If the Interface Queue is Full. SOLUTION: SEE SECTION III. 16) From ether_ouput() a)When there is no space in the first mbufs an attempt is made to fetch another mbuf to place the header. Then it could runout of mbufs: SOLUTION : increase the mbufs(in general) SEE SECTION II b) If the Interface Queue is Full SOLUTION: SEE SECTION III. SECTION II: - - - - - Most ENOBUFF errors can be resolved by increasing the number of mbufs available. However, in some cases the error may be caused by one of the following: a) in the network stack it self OR b) the amount of memory the target has OR c) The CPU speed itself. d) Design & Bugs from the regular BSD stuff itself, It could be a limitation of the RFC itself. In these cases, the error may not be corrected simply adding mbufs, as described in the section above. First, to debug possible problems caused by by insufficient mbufs, use the command netstackSysPoolShow(). >From target do -> netstackSysPoolShow() type number --------- ------ FREE : 1095 DATA : 0 HEADER : 0 SOCKET : 4 PCB : 4 RTABLE : 12 HTABLE : 0 ATABLE : 0 SONAME : 0 ZOMBIE : 0 SOOPTS : 0 FTABLE : 0 RIGHTS : 0 IFADDR : 4 CONTROL : 0 OOBDATA : 0 IPMOPTS : 0 IPMADDR : 1 IFMADDR : 0 MRTABLE : 0 TOTAL : 1120 number of mbufs: 1120 number of times failed to find space: 0 number of times waited for space: 0 number of times drained protocols for space: 0 __________________ CLUSTER POOL TABLE _________________________________________________________________________= ______ size clusters free usage -------------------------------------------------------------------------= ------ 64 160 153 8 128 160 10 23 256 160 4 12 512 80 76 16 -------------------------------------------------------------------------= ------ value =3D 80 =3D 0x50 =3D 'P' ( The Lower values of "free" shows that it is running out of NUM_SYS_128 & NUM_SYS_256 ) and then increase the required values of Example: #define FACTOR 4 #define NUM_SYS_64 FACTOR*40 /* 64 byte system clusters */ #define NUM_SYS_128 FACTOR*40 /* 128 byte system clusters */ #define NUM_SYS_256 FACTOR*40 /* 256 byte system clusters */ #define NUM_SYS_512 FACTOR*20 /* 512 byte system clusters */ AND do similarly with mbufShow ->mbufShow() and increase the required values of #NUM_NET_MBLKS FAC*400 #define NUM_64 FAC*100 /* no. 64 byte clusters */ #define NUM_128 FAC*100 /* no. 128 byte clusters */ #define NUM_256 FAC*40 /* no. 256 byte clusters */ #define NUM_512 FAC*40 /* no. 512 byte clusters */ #define NUM_1024 FAC*25 /* no. 1024 byte clusters */ #define NUM_2048 FAC*25 /* no. 2048 byte clusters */ in the ../target/h/netBufLib.h then bulid vxWorks image and boot the target to take the changes into account. SECTION III: - - - - - - A) For 7) of SECTION I increase the values of SO_SNDBUF/SO_RCVBUF either in the ../target/h/sys/socket.h file or use setsockopt carefully in your application.More explaination on setsockopt() can be found in the vxWorks Reference Manual.. B) Running out of mbufs at the interface Q level. You can see this when you do an ifShow() and it will show a lot of output errors ( oerrors++). So try increasing the maxlen value of the if_snd Q to the appropriate value. By Default it is 50. Try with 100 or so. #include "vxWorks.h" #include "ifLib.h" #include "etherLib.h" /* Run this script each time you boot the target or make it a part of the application */ void ifq_maxLen(char *name, int len) { struct ifnet *ifp; ifp =3D ifunit(name); if (ifp =3D=3D NULL) printf("error:in if unit\n"); ifp->if_snd.ifq_maxlen =3Dlen; printf("set ifq maxlen %d -> %d\n", ifp->if_snd.ifq_maxlen, len); } NOTE : This Summary lists some possible reasons for the ENOBUFS error. It is not meant to be all inclusive. Nor will the resolutions correct all instances of ENOBUF errors.

For anyone who has the time to read all this and a relative amount of expertise with the FEC ! I'm a newbie to FEC drivers (and the 8xx in general) and I'm trying to get my motfec up and running on my target board , loosely based (meaning ->not as populated) on the MdpPro8xxT BSP ...the transceiver I'm using is the CTX1170 canary module that connects to an MII interface on both boards, I wired that identically on my target as was done on the Eval Board. To let you know where I currently am with the FEC driver : (I'm downloading the vxworks image via visionprobe and using visionclick to debug it, once again , my target is the 855T , the BSP-template is the MdpPro8xxT and I've configured both boards using the register file download facility of visionclick , not worrying about boot-romming yet) * The Canary on noth boards start up in the isolation mode (On the module , this is configurable by a switch and its purpose is to restrict ethernet activity unless software configuration is performed) This "isolation mode" seems evident from the way the canary module behaves , with the 100MBps and link lights blinking in a wait-state. * The MdpBasicPro8xxT BSP eventually gets the link lights to stabilize in both cases, (at this stage I can see ethernet activity via the Rx Light) though this happens very fast on the Eval board (where I can consequently ping it from my host, observing Tx along with the Rx). This "waking-up" behavior takes a lot longer on the target board. I suspect a few timeouts elapse to account for this delay ? * Now , MOtFecEndLoad() , "THE" critical function on the BSP that loads the driver DOES NOT return an error or null value at any stage during its run. This I confirmed via breakpoints. * What DOES throw a spanner in the works is the MotFecMIIDiag() Diagnostics that follows up on the BSP , This asserts an error after the following code in the test-loop: if (motFecMiiRead (pDrvCtrl, phyAddr, regAddr, &data) != OK) return (ERROR); This is where the motfec fails on my target..as far as I can tell. WRS-Support seems puzzled ! * I also noted that for 860/855T processors , you have to take note of a D4 revision change. I believe the BSP takes into account this ...I'm using a D4 chip, anyhow. Could any one help me isolate the problem further ? Would really appreciate it ! Thanks !

Other schemes (taskLock and intLock) are not really meant to be used for mutex functions. Using taskLock and intLock for mutex can cause unpredictable system behavior in large systems. Use of taskLock can increase preemptive latency especially when used extensively. Use of intLock can increase interrupt latency. I have seen many large embedded systems built with VxWorks which assumes that taskLock and intLock can be used as convenient replacement for mutex semaphores. There are a lot of problems stemming from that assumption. If you need mutex, use mutex semaphores. If you want to disable task switching, use taskLock. If you want to disable interrupts, use intLock. But please do not mix the originally intended purpose.

We are using Tornado 2.02 and the related tools and have written a driver for an D/A, A/D converter PCI card. The driver is implemented using ioctl() calls. The PCI card generates interrupts at the end of conversion. The interrupt handler is connected using pciConnectInt and is definitly the only one for that interrupt line. Now we experience very looong delays from the interrupt signal on the PCI bus until the handler gets called. According to the logic analyzer, it takes between 5 and 15 milliseconds (with a strong tendency to 15ms)-- and this supposed to be an OS for fast hard realtime... We are using the standard Pentium BSP on various PC's, from 166MHz Pentium I to 2GHz Pentium 4. There seems to be no change that depends on the processor speed.

Right. The test seems not to be wrong: even without measuring hard- and software behaviour of the system is such that we had to suspect large interrupt latencies. The test only confirmed this.

One of the elements of this struct is the function pointer pScsiCtrl->scsiThreadAbort, so you could try running that. I'm not sure, but it may be the same function that is run when FIOCANCEL is called from ioctl. The arguments to the this function are a pointer to the SIOP (same as to the controller) and to the thread to abort. Both are in the scsi control struct, from memory it would be something like: (*pSysScsiCtrl->scsiThreadAbort)(pSysScsiCtrl, pSysScsiCtrl->pThread) You may also want to check the scsi control struct to see that a thread is in fact active (pSysScsiCtrl->active == TRUE) But is there a reason that you can't wait until the write has finished? One other thing with this BSP and SCSI is that the SCSI bus is not reset properly after a warm reset or a reboot. You need to perform a scsiBusReset(pSysScsiCtrl) before you do any scsi config, somewhere at the top of sysScsiConfig( ) seems to work okay.

I am trying to use DIAB 4.4b compiler on PowerPC. Found out that it is VASTLY different from writing embedded assembly in GNU. Anyone have any experience in writing embedded assembly for DIAB? How would you translate this line from the GNU? In GNU, I write my function like so: unsigned short gt_ld_le16(const volatile unsigned short *addr) { unsigned short val; __asm__ __volatile__ ("lhbrx %0,0,%1" : "=r" (val) : "r" (addr), "m" (*addr)); return val; } I would write it in DIAB like this: asm unsigned short gt_ld_le16(volatile unsigned short *addr) { %reg addr lhbrx r3,0,addr blr } is that correct? Can I insert a '0' like in the example? how are storage mode 'con' used? Windriver's DIAB C/C++ Compiler User Manual gives a really crappy example (an example with little features) on how to write this code.... Just curious.

Because they are different. The discussion you sited says that the `ifShow' command call an ioctl() function with "EIOCGADDR" to retrieve the MAC address. I imagine that the MAC will be the same when the original ioctl() is called. The problem with this is that the driver might not know the MAC when the interface comes up. It might take a while to read out a MAC address. Dave Laight also mentioned that the info is in the "if_net[]" array. You could peruse through this to discover things. I have done the same thing with the file system array. It is possible that some bad code overwrites this stuff. You might have other weird effects if this happens. hth, Bill Pringlemeir. - -- Hydraulic pizza oven!! Guided missile! Herring sandwich! Styrofoam! Jayne Mansfield! Aluminum siding! Borax!

They all work together as part of a particle accelerator control system (EPICS). From time to time we lose connectivity between one or more of the 162's and a solaris host. We suspect network storms of as yet unknown origin. I am attemping to time correlate the occurences by logging network stats gleaned from "ifShow". I have also looked directly at data in the interface structure pointed to by the function "ifunit". Other than "packets received" none of the values gathered by the two methods seem to agree. As you can see ifShow reveals a number of input errors and no unknown protocol counts. The raw data show quite the reverse sort of. Can anyone tell me what the numbers really mean?. Does ifShow some how juggles the raw data or does it come from some other data source?.

I am not sure what you mean by "fixed values". If they are compiled into the bootline, then fix them! If your "device" gets this information via DHCP then fix the configuration of the DHCP server. Bottom line is that to send an IP datagram off the local subnet you MUST go thru a router that has an interface on the subnet as your device. --------------------------- Newsgroups: comp.os.vxworks Subject: Re: Bsp Testing Date: 3 May 2002 17:59:17 -0700 From: john_94501@yahoo.com (John) Organization: http://groups.google.com/ Message-ID: <488e459a.0205031659.6ccd1706@posting.google.com> References: <9e221d1.0205030538.4466b5b1@posting.google.com> Hello, > I am developing a BSP for PowerPC.

It might be well worth getting a JTAG debugger if there is one available for your board (or could be connected to it). That might save you some time in the long run. If that's not possible, here are some basic tips: 1) Do not use the compressed format image; it makes things more difficult to debug. In fact, I would suggest working not with the bootrom image at all; instead used a ROM version of vxWorks itself, and add the target tools to it (i.e. the target based shell, standalone symbol table etc). 2) Reduce the kernel to an absolute minimum. Take out everything except the serial port support (e.g. no network code, no disk support etc). Burn that image, and get it working. If it crashes at this point, you really are left with only LEDs on the board, or some external hardware assist (e.g. a JTAG solution). 3) Once the serial-only config works, add the network code and one driver. If this crashes, you should at least have an address where the failure was, and with some work you can find where in the code it occurred. If you are running a full kernel, with a bit of luck you'll have the target shell to help you. If the crash is proving difficult to find, leave the network code in the system, but remove the init calls for it. That way it will boot up to the target shell prompt, and you can make the calls from there to see which one fails. You should also be able to get a stack trace which might prove helpful. 4) As long as the code that is crashing is after the serial I/O init, you can use printf() or logMsg() to generate diagnostic messages. This is often useful in tracing calls and checking parameters. 5) For cases where the thing crashes and reboots, but you don't know where it is. Try using LEDs, or other output devices. If none of those are available, you can always add calls to reboot(1) into the init sequence to see how far you get (this is going to be a slow process with ROM though).

What if down the road it is necessary to make Task A a higher priority than Task B. It will now have to be redesigned to add mutual exclusion.

Keywords: semTake intLock block Message-ID: Hi, I stumbled upon a piece of code which takes a VxWorks mutex semaphore within a intLock()/intUnlock() section: - --- 8< --- cut here --- 8< --- cut here --- 8< --- lockKey = intLock(); /* ... */ rc = semTake(mutexSem, timeout); if (rc == OK) { /* ... */ } else { /* ... */ } /* ... */ intUnlock(lockKey); - --- 8< --- cut here --- 8< --- cut here --- 8< --- I thought we could not block after intLock() (hence taking a semaphore was a no-no). However after looking at it, experimenting and reading the reference manual, I see that blocking after inLock() will schedule another task. Scheduler will unlock interrupts as part of restoration of the new task TCB. When the task that locked interrupts and blocked on semaphore becomes ready again (semaphore was given), it will be rescheduled and interrupts will be locked again. If that's correct, I suppose that the above code is somewhat equivalent to: - --- 8< --- cut here --- 8< --- cut here --- 8< --- lockKey = intLock(); /* ... */ intUnlock(lockKey); rc = semTake(mutexSem, timeout); lockKey = intLock(); if (rc == OK) { /* ... */ } else { /* ... */ } /* ... */ intUnlock(lockKey); - --- 8< --- cut here --- 8< --- cut here --- 8< --- Second piece of code has more overhead and will unlock interrupts even when semTake does not block. However, it does not take the semaphore in intLock. It makes it explicit that interrupts are unlocked. It should be better for interrupt latency as it always unlocks interrupts. I'd like to make sure that this is really what is happening. - -> Is it acceptable to take a mutex semaphore after intLock? (assuming we understand that interrupts might be temporarily unlocked as result) Taking a semaphore in intLock looks like a poor coding technique to me at best and buggy at worse. The piece of code has been running well so far but it does not mean it is correct.

Just because a device implements some ioctl() functions doesn't mean it will do them all. In fact, the pipe driver does not implement FIONBIO so you will not be able to use the line below to get non-blocking behaviour. > status = ioctl (sFd, FIONBIO, &on); Of course, if you need non-blocking pipes they are pretty trivial to implement yourself... you can even do more unix-like stream based pipes if you don't like the standard ones.

Blocking with interrupts locked is possible, and has the semantics that you discovered.

In the first case, interrupts never get unlocked. In the second case, interrupts do get unlocked for a short period, which may open up race conditions, depending on what the intLock() is attempting to protect against. If your timeout is non-zero, and the semaphore is unavailable, the same race conditions occur in both the cases. However, if the timeout is zero, and the semaphore is unavailable, the first case will not have race conditions, but the second case will. > -> Is it acceptable to take a mutex semaphore after > intLock?

Obvious places to start are in the BIOS - see what the settings are there, and if any of them could be causing the problem. After that, what is the chipset on the new boards? Perhaps that is causing the problem somehow. After that, try to find something you can use to mark progress (perhaps an LED somewhere, or for a PC type platform you can even write to the video memory - doesn't have to be anything more than just something appearing somewhere on the screen). Look in the bootApp project at the prjConfig.c file - this contains the boot sequence - by adding progress markers to this you can get some idea of progress through the sequence. Finally, since you mentioned that you were having problems with the serial port on the board anyway, you might like to make the changes to the bootApp configuration to use the screen + keyboard console instead of COM1. That might come up if the problem relates somehow to the serial devices and/or PCI/ISA handling on the board (perhaps an unrecognised bridge?).

I am able to build a bootrom that I can configure via the serial port. I am attempting to boot via Ethernet/TFTP, but am unable to get the ethernet connection working. I have a Kingston KNE100TX board that has a Digital (Intel labeled) 21143 chip on it. When the bootrom attempts to load the file, nothing comes out of the ethernet port and the sandpoint hangs. There are no error messages and the board doesn't reboot. If I remove the board and retry, it reboots after a while and tries it again. I'm wondering if I need a different Ethernet card. The target.nr file for the sp7400 bsp has a list of supported chips followed by a list of ethernet cards. Do I need one of those? Maybe a different one?

Also, note that some of the calls you are using, e.g. dosFsMkfs() are not native DosFs 2.0 calls, but are backward-copmatibility routines, emulating dosFs 1.0 calls. I suggest that you avoid the backward compatibility calls, and call dosFsVolFormat() directly, and specifically specify the option which wipes the volume blank before formatting, instructing it to disregard any values it may find on the RAMdisk (see manual for details). - - Leonid "Harish" wrote in message news:3b36664c.0205071715.5057dd84@posting.google.com... > Can anybody tell me why dosFsVolFormat() fails (error 0x16) > and how to solve this?? > What does" Malformed boot sector.

Hi, m2IpRouteTblEntryGet( ) routine compares routing table entries to the address specified by the ipRouteDest member of the pIpRouteTblEntry structure, and retrieves an entry if a match is found. If the address is not specified, the m2IpRouteTblEntryGet( ) retrives the first entry in the routing table. The remaining entries in the routing table can be retreived by doing a SNMP GetNext request on the recieved entry from m2IpRouteTblEntryGet( ) call. The subsequent GetNext requests will retreive the remaining entries in the routing table sequentially.

We want to start using it in Tornado 2, and using the Tornado 1.0.1 Build compatibility in Tornado 2, the BSP compiles without errors. The problem is that it will not run on our target system. Comparing the build output from Tornado 1.0.1 with that from Tornado 2, I only find a difference right at the end of the output: (we build vxWorks_rom.hex images). It seems that the size of the images are different. I have no idea why. In T1.0.1 the linker seems to be used, while in T2 they use the compiler to link the modules. Any ideas?

Looks like you do not clear the interrupt source, so after you finisch the interrupt routine it jumps right back in it again, because the interrupt is still active.

We are using Tornado 2.0.2 and VxWorks 5.4.2 with 386EX targets since 2000. After 1 year with support contract, we decided to leave it, because of the percieved low quality/cost ratio (of course, I agree this is a very subjective appreciation.) We will continue to use these targets (and perhaps another ones, mainly 486DX based) instead of Pentium ones, because of cost considerations (we manufacture our own boards, or use cheap standard ones.) So we will have to stick to Tornado 2.0.2, even if someday we decide to upgrade... My condolence. These news are bad news for us too.

Unless of course, someone or something has instructed the CPU to block interrupts. (Note: on x86 processors,l the CPU can either block all or allow all interrupts as it has got only one INTR pin). What I am saying is that you need to find that bugger ;-) who put tons of code between intLock() and intUnlock() calls, code that runs for 5-15 milisec. intLock gets used in the kernel a few times, but trust me, the VxWorks kernel or any other subsystem do not do anything THAT STUPID.

Well, the ARM COFF format with T2.1.1 are different than T2.0.1. However, I would suspect that you might have some cache coherency problem. Does the function not work properly if you run it? What does "objdump960 --all-headers testB.o" show for the relocation and symbol records for the functions in question. Likewise for the testA.o file. This information would be most helpful. Also, run `@lkup "funcA"' and `@lkup "funcB"' from the shell. Also try `lkup "funcA"' and `lkup "funcB"'. This will give some clue as to a possible host/target symbol table mismatch. A symbol entry will look like, [ 25](sec 0)(fl 0x00)(ty 20)(scl 2) (nx 0) 0x00000000 _funcA [ 26](sec 1)(fl 0x00)(ty 20)(scl 2) (nx 0) 0x00000000 _funcB ..

I've used similar code with TCP sockets (where Tx and Rx state interact) without problems. Since a socket must be some form of waitable object (how does recvfrom() actually block?), then closing it releases waiting tasks, returning an error code to their caller.

That looks wrong. Obviously the text 'This file...' should be in a coment block, but isn't. Why should a cross-compiler need to include a BSP-specific vxworks.h anyway?

If a socket is closed while some task is blocked on it, or if a task is using a previously closed socket, the call will return an error, probably "Invalid file descriptor". Now to the architecture of yours: There is one reason to use more tasks - to prioritize work. There is a cost to pay for more tasks - more memory going into stacks and more difficult to debug. My feeling is that you can probably do all this without message queues and with a single task doing reception, processing and transmission, but of course this is hard to tell without knowing your specific application requirements.

I use Intel END/BSD (same behaviour) driver for VxWorks. When I configure only one adapter everything works fine. However when the driver is configured to work with both Ethernet adapters, the network response sometimes becomes slower. As a test I ping the board from/to other computer (either same board connected via cross cable or another computer). When only one adapter is configured in the driver, each ping always takes exactly 1 ms. However with two adapters about 5% of pings have a response time of 10 to 80 ms. The second adapter is enabled in driver only, no TCP/IP is bond and it is not connected to Ethernet. (I tried to configure IP address of it and connect it to Ethernet as well - the same result). I am confident that it is a problem of software, because I saw with WindView that tNetTask sometimes becomes active (when two adapters are set) and if the ICMP echo request arrives at that time, the response time is higher. Both Ethernet adapters work fine together under Linux. The configuration is: { 0, EEE82559_LOAD_FUNC, EEE82559_LOAD_STRING, EEE82559_BUFF_LOAN, NULL, FALSE}, { 1, EEE82559_LOAD_FUNC, EEE82559_LOAD_STRING, EEE82559_BUFF_LOAN, NULL, FALSE}, where all defines are standard.

If one task closes a socket (or any fd, for that matter), while another task is still attempting to operate on it, Bad Things might happen. If the Rx task is *acutally in* recvfrom(), and waiting on the semaphore for that socket, then it will get an good error code from recvfrom(). However, how can you tell this from the Tx task? What if the Rx task is just about to call recvfrom() when the Tx task closes the socket, then another task jumps in and opens another socket? Then, the Rx task does a recvfrom() on another application's socket, which is not what you want at all. You really need to view open()/close() (or socket()/close()) just like malloc()/free(). Both are managing access to a set of dynamically allocatable, globally shared resources. If one task is still operating on a memory region when another task free()'s it Bad Things will happen. The same argument holds for one task operating on a socket or fd when another task close()'s it. Any time you have tasks sharing resources, you need to make sure that all tasks are done operating on the resource before you free it up.

OTOH you could guess where it might be and set a breakpoint (having removed the VX_UNBREAKABLE flag from tNetTask) - again from the target shell. If the system is actually busy-looping, a statistical code performace moniter would help - ie something that takes a fast timer interrupt and builds a histogram of the interrupted PC. I don't think vxWorks has one..... but very useful for finding out which piece of code to optimise.

ECC can recover from single bit and certain double bit errors, depending on the logic being used. Parity can only detect errors, without recovering the data. The time required to calculate either parity or ECC is practically buried in the memory logic; however, error detecting/correcting memory is more expensive. You have to consider the statistical probability of encountering a memory error over the life of the product to justify the use of error-detecting/correcting logic. > + Would it be inconsistent if I choose not to, say, do the same memory > data error checking on DRAM?

It all depends on when you place guarantees on when the data is "valid". If you apply a suitable CRC check to a block of memory when you can guarantee its correctness, you can always be able to determine if the data is correct later on when you retrieve it or store it somewhere else.

What I can think of as a possible reason to this blocking is the mutex - the net stack has a single mutex (emulation of splnet() and splx() .. ) and any socket or other net function would block if someone else has taken up this mutex. In your case, unplugging the cable may mean that the driver has to go into PHY auto-negotiation phase. We have already dealt with the problem of netTask going into lengthy processing pohase while doing PHY autonegotiation, and surely enough the netTask executing driver code would be taking the splnet mutex.

I believe UDP sockets should block for (local) flow control reasons. I'm fairly sure the SuS allows send() to block, and probably expects it to. For instance a process level NFS stack will not work if the UDP datagrams are discarded just because the network is busy, or some internal socket send buffer is full.... Clearly UDP traffic CAN be discarded - but it should only be done to relieve a buffer crisis.

Looking at the source for the network stack, a UDP sendto() call is checking the non-blocking state flag (and will return EWOULDBLOCK if necessary). It also calls sbwait() if the local send buffers are full and non-blocking is not set. I would conclude that it is possible for a UDP socket to block on sends at least.

Changing the write protect bit on the flash/PROM is not normally something I'd expect the toolset or loader to be involved in. I would expect the memory description of the OS to flag the area as read-only, and any software that is going to write to it to modify that protection while it writes to the flash and then restore the protection afterwards. > > + As far as error detection/correction is concerned, there're choices > > - normal parity > > - read-modify-write parity > > - ECC correction and checking > > when do we use which one?

I've never heard of anybody using ECC on flash/ROM. For a start, you need more bits (even the simple parity checking requires at least one extra bit). Secondly, writing to flash is performed using a procedure that requires commands to be presented to the device on the data bus - ECC would "corrupt" these commands, making it impossible to write to the flash from software (you can't disable the ECC to write since the content of the flash needs to be encoded for the ECC to work). Finally, to put the initial image in the devices, you would need something that could generate the ECC inclusive images from the ones produced during your build process. I think you should forget any ideas of doing ECC on Flash (unless you can find flash devices that support it internally). Checksumming (or similar) operations are much more viable for flash/ROM devices.

I think that you either have a bad copy of vxWorks.h, or maybe you have picked out the wrong line. The compiler doesn't always print correct line numbers for errors. BTW, on my copy of vxWorks.h, the text "this file.." does not appear. I see the line "/* Copy... " followed by a blank line, and a comment block with mod history.

Forgot to add. It's generally more involved to change flash content; one has to write a sequence of programming commands before one can write to the memory.

I have 2 requirements 1. Doing FTP through PORT command where I will specify the port on which the server can intiate data connection on receiving commands on the control connection. 2. Second is, I want to use PASV command where the server will reply with a IP,PORT number on which I can connect to. So when the remote ftp server receives a ftp command , the data transfer occurs on this server specified port. The problem I am facing is, 1. When I use VxWorks API ftpCommand() for issuing a PORT command I CANNOT intiate a data connection to the port which I have specified, using the ftpDataConnInit() and ftpDataConnGet(). 2. When issue a PASV command using ftpCommand(), all that I get in the reply is number '2' which Stands for FTP_COMPLETE. Bull the actual thing I want is the commplete 3 digit reply and the IP,PORT numbers from the reply. It seems that the vxWorks API somehow restricts the reply to the first digit from the actual reply. So, the vxWorks APIs dont seems to help. 1. Is there anyway I can still use the vxWorks API for acheiving the above. 2. If not, what is the alternative. That does mean that I have to implement my own FTP client in the vxWorks. Thanks for all your replies.

[FAIL]\n"); return(ERROR); } ret = dosFsDevCreate(filename, pCbio, 30, DOS_CHK_REPAIR | DOS_CHK_VERB_SILENT ); if (ret == OK) printf("\rInitialize DOS File System .................................. [OK]\n"); else { printf("\rInitialize DOS File System .................................. [FAIL]\n"); return(ERROR); } return(OK); For the compact flash with 512-bytes block size, this initialization code runs well. But for the compact flash with 600 bytes block size, the cbioDevVerify(pDev, FALSE) returns NULL! Is the DOSFS 2.0 supports block size other than 512 bytes? I've tried the DOSFS patch SPR73141, which fixed the problem "dosFs2 is not handling boot sectors correctly on devices with sector sizes != 512 bytes." . But the results is still the same, no works on flash with 600 bytes block size. Any suggestion is welcome! Thanks in advanced!

Although I am quite old too (I use computers since 1980), the entient history and highly specialized areas of critical systems and aero-space where not considered in these thoughts. Regarding the system testing, and the Marsk fiasco, I agree partly - testing does not come instead of good design and code review. Still, the ability to test the system as a whole, and lack of software modifications in teh field, does make the embedded system orders of magnitude more testable then general purpose IY systems. Of course the discussion of how good is a test, is something else .. By the way, I recall that in the old days, a VAX/VMS real-time systems where sort of dedicated to a single application, and and RT did take away some of the inter-application protection measures (i.e. an RT task could easily crash the entire system), so in my mind, they where rather similar to embedded systems, disregarding their physical size. Lastly, I cannot resist noting the PBX case (e.g. DMS) as a very special case, where real-time actually co-exists with multi-application, and software changes are indeed made in the field all the time, ...

My nect problem is I am working with a flash driver which implements the dosFs on flash. I find that the read & write handlers receives only 2 blocks of data at a time. I have declared the block size as 512 bytes. In one shot I receive only 1024 bytes of data to be written to the flash. This happens independent of the file size which has to be written to flash. This drastically slows down the system. I would like to know if I can dictate the vxWorks dosFs to transfer the file to driver with chunk size much higher than this 1024bytes. Plz mail me regarding the dosFs transfer block size.

I'm using a MVME2700 single board computer from Motorola.  I have 4gig of VME A32 addressable memory which is mapped using BAT registers.  Has anyone experienced poor performance the first time through a section of code?  For example, the first time through a function may take 118us, whereas future accesses through it only takes 82us.  The code does not dynamically allocate any new memory via malloc.  I'm guessing that the translation look-ahead buffers (TLB) on the MVME2700 PPC are remembering the previously accessed locations, thereby decreasing future VME A32 access times.  If this is so, how can I estimate when the TLB's will forget or lose this information, requiring another performance hit?

If anybody has had similar experiences with the BAT registers and has some ideas on how to increase VME A32 memory performance, please respond.

Thanks,

The TLBs are not consulted (i.e. used) when you use the BATs, for that particular memory region. (See the Green Book for more info). If you map other areas with page table entries, the TLBs will be used for them. But TLBs are never used for areas mapped by BATs. The code may not dynamically allocate new memory, but are there memory locations (i.e. global variables, local vars on the stack) that may not be accessed until you execute the code the first time ? I'm not completely familiar with the MVME2700. Is the 1G of A32 on board or across the VME ? Are there other bus masters that may invalidate your cache ?

Your 'problem' might be caused by cache: The first time your code is executed, it has to loaded into instruction cache. You may test the delay by commenting out the VME access and messure again. Take care: When writing to VME, you don't get the actual time of VME access, as your PCI2VME (Tundra Universe) does posted writes in basic setup. Try reads to get a feeling of real world.

Yes, but the problem is that the address of the gateway is outside the subnet. I managed to get it to work (sort of). After I received the data from the DHCP server I had to implement the following sequence: ifAddrAdd ("dp0",); routeAdd ("0.0.0.0",); arpAdd (,,0); For some reason the ARP does not work correctly on the second IP address, so I had to add the entry manually. This also gives problems with the DNS server. When I ask for an address the query is sent out on the second IP address, as this is the address of the DNS resolver in the box where the DHCP server is also located. But that box sends out an ARP, but this ARP is not answered by the VxWorks box.

How should this work? The simulation runs on your host (Windows or Solaris), so it must be compiled for the host's architecture and file format (e. g. it must be in PE - portable exe - format on Windows). This should not prevent you from testing your application, unless you have some hardware specific stuff used there. In that case, you need to write a simulation for this parts of the project or exclude them from the simulation. If you want to achieve something else, please specify what exactly. hth Werner "yyzhong" wrote in message news:b35585ab.0205081909.64d797e7@posting.google.com... > I need to use a simulator oriented to a project based on PentiumGNU. > But I don't know how to build it. > Is it possible?

What I expect that you want to do is have multiple ethernet controllers starting up during the boot instead of only one. I don't think this is documented. If you want to do this you have to modify the bootrom code. Also if you want to do this from the application you have to initialise your network yourself. But it is not very difficult: ipAttach (, ); usrNetIfConfig (, , , , ); So for example: ipAttach (1,"fei"); usrNetIfCOnfig("fei", 1, "10.20.30.40","Interface2", 0xffffff00); But you need to configure your interface in configNet.h first.

I have added an extra function to the motfecend driver that uses existing functions to read the status using the MII port on the MPC860. The link status is checked when the device is being configured after the auto-negotiation and this returns the correct status. After the status comes back ok the device works as normal. If I try to call the exact same function with the exact same settings to read the status from the PHY, the return value is always all 1's (0xFFFFFFFF). I am calling the 'get status' function from a timer expiration call and it seems to work as the FEC generates an interrupt to say the message transaction is complete. Any help would be very appreciated. --------------------------- Newsgroups: comp.os.vxworks Subject: Re: FTP Site Date: Tue, 14 May 2002 11:57:02 -0700 From: Joe Durusau Organization: Lockheed Martin Corporation Message-ID: <3CE15DFE.E2434894@lmco.com> References: MURALI wrote: > > Hi, > > I was trying to access the site > > ftp://ftp.ece.ucdavis.edu/pub/snmp/ucd-snmp.tar.gz > > but could not access the same.

The link is Johan's vxWorks FAQ, i.e. http://www.xs4all.nl/~borkhuis/vxworks/vxworks.html. See section 4.1 (network configuration) for the sequence of steps necessary to bring up multiple END devices. As Johan pointed out earlier, you should have all of them already in the END_DEV_TBL defined in configNet.h. And the code in usrNetInit() (whether it's in the application or bootrom) should have run muxDev{Load,Start} on them. Then it's valid to call the code in the link above. hth, Dan Gold gold@ensemble.com --------------------------- Newsgroups: comp.os.vxworks Subject: Re: ENVOY SNMP Date: 14 May 2002 11:02:20 -0700 From: jzhang@drs.ca (Jason) Organization: http://groups.google.com/ Message-ID: References: <3CD35445.8123C2F0@worldnet.att.net> Eventually I know what the problem is.

Tornado shell on machine a (win2k). Host machine( machine b, NT) has a PCI card with a variant of VxWorks running (IxWorks) When I'm executing my code (its a very long path), I'll get this (Serial@machinea): Sat May 11 19:50:55 2002 Error: clnttty_rcv: read timed out Error: rpccore backend client Timed out Warning: tgtEvtGet: cannot get event. Now, I can put in debug statements to send messages to my tornado shell and, in fact, do this. But, the timeout appears to move if I add/change code. Is there any way to track this down during execution? After the timeout occurs, there's really nothing that can be done. Some of the suggestions I've seen/heard for the cause of timeouts are that a pointer is unitialized and a thread is taking too long to finish something. I dont have support, so I can't use the Windriver database. Any suggestions are appreciated. Thanks.

The uart works only in interrupt mode. It does not have the transmitter ready interrupt. Instead it has the Tx Buffer Full interrupt. All the uart drivers (including vxworks template SIO driver) that I have seen considers only transmitter ready interrupts and not Tx Buffer Full interrupt. I appreciate any pointers on how the driver should handle transmission.
