local_irq_enable() should only be doing an sti; your code has an extra

tsk was zero here, implying that current was 0 when the page fault happened.

Andrew, should we add debug code to the fault handler to test for current == 0?

I'm not sure what debugging we could usefully add to the pagefault handler to detect that. Apart from getting a good backtrace. Which the x86_64 guys have broken. Laurent, please disable CONFIG_STACK_UNWIND and try again - that way we should be able to see whereabouts the thread-info got corrupted. ^ permalink raw reply [flat|nested] 179+ messages in thread

I tried 2.6.17-rc5-mm2 with CONFIG_STACK_UNWIND disabled today and the bug still happened. But I can't get a full stack trace right now since I don't have my second box here.

Maybe we could modify the check-for-stack-overflows code with 8k stacks to be "check for overflows which would kill a 4k stack kernel".

I'd be surprised if it has to do with the packet code - more likely someone screwed something up in the lockdep/genirq/unwind area and the kernel went recursive. I tried it here, couldn't reproduce it. Laurent, can you (re?)send the offending .config? ^ permalink raw reply [flat|nested] 179+ messages in thread

Laurent, can you (re?)send the > offending .config? .config is attached I run a few additional tests: - 2.6.17-rc5-mm3 + CONFIG_DEBUG_STACKOVERFLOW=y, CONFIG_DEBUG_STACK_USAGE=y, CONFIG_4KSTACKS=y: system freezes right after typing "pktsetup test /dev/dvd". No stack trace printed. - Same config as above + lockdep-combo-2.6.17-rc5-mm3.patch + lockdep-tracer-2.6.17-rc5-mm3.patch: Random Oops (recursive dies) on early boot. I sometimes succeded on booting but the system dies on "pktsetup test /dev/dvd". I can't get a full trace since I don't have my second box here for some days. I tried to boot with vga=791, but system hangs with a blank screen. -- laurent [-- Attachment #2: config-2.6.17-rc5-mm3 --] [-- Type: text/plain, Size: 42992 bytes --] # # Automatically generated make config: don't edit #

The first column is, I assume, stack usage by that function? blkdev_get() allocates 700 bytes of stack space. Do you have any lockdep features enabled in config as well? They will increase the size of the inode and dentry to a total of over 2 kbytes and we'll really start getting into trouble in blkdev_get(). But I don't see why the above trace is (apparently) claiming that do_open(), ptk_open(), etc are using a lot of stack. I guess we should force 8k stacks if the lockdep features are enabled. But x86_64 has no such option. Problem. <wonders how on earth that on-stack inode+dentry got in there> And lock-validator-special-locking-bdev.patch add two more copies of the same sin, while falsely claiming "Has no effect on non-lockdep kernels." ^ permalink raw reply [flat|nested] 179+ messages in thread

In a few words, here is the situation: Scenario: - boot to runlevel 2 - modprobe pktcdvd - pktsetup dvd /dev/dvd Results: - 2.6.17-rc4-mm3 with 4K stack works fine (this is the latest good 4K-kernel). - 2.6.17-rc5-mm3 with 4K stack crashes, the stack seems to be corrupted. - 2.6.17-rc5-mm3 with 8K stack works fine. - 2.6.17-rc5-mm3-lockdep with 8k stack works fine, although it exhibits high stack usage while running pktsetup.

No, I managed to trigger higher footprint while mounting a packet-formatted DVD. I didn't sent it because: - this operation (mounting a packet-formatted DVD) wasn't part of my crash scenario. - It wasn't a *vanilla* 2.6.17-rc5-mm3-lockdep as I started to hack driver/block/pktcdvd.c to reduce stack usage (changing stack allocation to kmalloc in pkt_generic_packet() and in pkt_get_max_speed()).

The kernel does this in a lot of places, and at 168 bytes on x86, it'd really be best if we were to dynamically allocate these things. However there are no locks in the request struct, so lockdep hasn't worsened that part of the stack usage. There could be lock-heavy automatically-allocated structs lurking all over the place - the least path of resistance here is to require 8k stacks for lockdep. ^ permalink raw reply [flat|nested] 179+ messages in thread

It's nasty from several angles, stack usage just being one of them.

Let me say I successfuly run a 2.6.17-rc6-mm1 kerenel with 4K-stack and CONFIG_DEBUG_LOCKDEP=y, so I guess my stack problems are fixed. I got a "possible circular locking deadlock detected" while loading pktcdvd service, I'll make a detailed report in another thread. .config is attached for information. -- laurent [-- Attachment #2: config-2.6.17-rc6-mm1 --] [-- Type: text/plain, Size: 42943 bytes --] #

Something strange is happening with the stack. Can you try with 8K stacks?

The BUG still happens with 4K stacks, but the system runs fine with 8K stacks. Another info: the system is able to run fine with the following scenario, even with 4K stack: - boot to runlevel 1 - load pktcdvd (modprobe + pktsetup) - then go to runlevel 5 It fails if pktcdvd is loaded at runlevel 2 or higher. -- laurent ^ permalink raw reply [flat|nested] 179+ messages in thread

If you want a generic memory eater you can use memhog from numactl. It's mainly a quick test for machines that error out when they detect a 2 bit errors using ECC. And when run for longer it tends to stress other parts of the motherboard like VRMs. At least on Opterons with ECC memory it seems to detect most memory problems pretty reliably, that is why I suggested it to Martin. -Andi > > ^ permalink raw reply [flat|nested] 179+ messages in thread

The x86_65 panic in LTP has changed a bit. Looks more useful now.
Possibly just unrelated new stuff. Possibly we got lucky.

Are you able to narrow it down to a particular LTP test? It was mtest01 or something like that? Perhaps we can identify a particular command line which triggers the fault in a standalone fashion? And why can't I make it happen? Perhaps it's a memory initialisation problem, and it only happens to hit in that stage of LTP because that's when you started doing page reclaim, or something? Perhaps just try putting a heap of memory pressure on the machine, see what that does? Being unable to reproduce it and not having a theory to go on leaves us kinda stuck.

It consistently happens on -mm, and not mainline, flicking back and forth over time.

Yeah, we have a sniff-testing mechanism that works well. However, drill-down still requires significant amounts of human intervention. The next gen of stuff should help do more intelligent stuff, but we're kind of stuck with human-ness for now. M. ^ permalink raw reply [flat|nested] 179+ messages in thread

I am sure I got half way through diagnosing this one. We were context switching to a bad thread. I've been meaning to get back to it.

We are still handing off threads with non-initialised stacks. APW: schedule: ffffffff805f0cd8 bad rsp flags=00000000 Kernel panic - not syncing: BAD STACK POINTER Interestingly this has remained unchanged for dispite the major churn -mm takes so this could well be the underlying issue as we almost always blow up randomly when we do this, in a mess with no stack to work with. Last time I tried to split search -mm1 and she was being a hideous pig, I just couldn't get any bit of it to compile without the rest. Will try and track this down with the new -mm. -apw ^ permalink raw reply [flat|nested] 179+ messages in thread

You shouldn't bisect blindly. Looking at the series file (ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17-rc5/2.6.17-rc5-mm2/patch-series): ... add-scsi_add_host-failure-handling-for-nsp32.patch qla1280-fix-section-mismatch-warnings.patch bogus-disk-geometry-on-large-disks.patch bogus-disk-geometry-on-large-disks-warning-fix.patch megaraid_sas-switch-fw_outstanding-to-an-atomic_t.patch megaraid_sas-add-support-for-zcr-controller.patch megaraid_sas-add-support-for-zcr-controller-fix.patch ... megaraid_sas-add-support-for-zcr-controller-fix.patch is a fix against megaraid_sas-add-support-for-zcr-controller.patch, so if the bisection lands you on megaraid_sas-add-support-for-zcr-controller.patch then obviously one should apply megaraid_sas-add-support-for-zcr-controller-fix.patch by hand as well. You'll often find great streams of similarly-named contiguous patches - you should apply either all of them or none of them. Otherwise you're testing a known-to-be-broken kernel which has an already-available fix ;) http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt describes the bisection technique I use. If you're using git-bisect, well, try to have a nice day anyway. > Will try and track this down with the new -mm. Would be great, thanks. ^ permalink raw reply [flat|nested] 179+ messages in thread

Will try > and track this down with the new -mm. Ok. Did a split search on -mm2 for this. With the full stack I was still tripping up on the bad thread hand-off trigger above. However, when split searching I seemed to get somewhat different panics pretty commonly in the allocator. My split search led me to the start of the swapless page migration patches: GOOD:page-migration-cleanup-pass-mapping-to-migration-functions.patch GOOD:page-migration-cleanup-move-fallback-handling-into-special-function.patch ----:swapless-pm-add-r-w-migration-entries.patch -BAD:swapless-pm-add-r-w-migration-entries-fix-2.patch I tried pretty hard to slide this out of -mm and can't say with cirtainty that I did it right. I backed out the following in order to get the first two off (obviously from the bottom up): swapless-pm-add-r-w-migration-entries.patch swapless-pm-add-r-w-migration-entries-fix-2.patch swapless-page-migration-rip-out-swap-based-logic.patch swapless-page-migration-modify-core-logic.patch more-page-migration-do-not-inc-dec-rss-counters.patch more-page-migration-use-migration-entries-for-file-pages.patch page-migration-update-documentation.patch page-migration-simplify-migrate_pages.patch page-migration-simplify-migrate_pages-tweaks.patch page-migration-handle-freeing-of-pages-in-migrate_pages.patch page-migration-use-allocator-function-for-migrate_pages.patch page-migration-support-moving-of-individual-pages.patch page-migration-detailed-status-for-moving-of-individual-pages.patch page-migration-support-moving-of-individual-pages-fixes.patch page-migration-support-moving-of-individual-pages-x86_64-support.patch page-migration-support-moving-of-individual-pages-x86-support.patch page-migration-support-moving-of-individual-pages-x86-support-fix.patch page-migration-support-a-vma-migration-function.patch allow-migration-of-mlocked-pages.patch That did seem to get rid of the original error. However, I'm now experiencing a reiserfs4 panic so I'm not 100% confident the problem really is gone, but the reiserfs panic isn't anywhere as near hard as the panic's I have been experiencing; I was able to reboot the machine even though the tests were not completing correctly.

Or does it require the fix-2 in order to happen? Without the fix page migration is broken. Does LTP include any page migration tests? Guess not? If not then this could be simply due to code rearrangement making the problem appear in a different way. Which test did this? Swap migration uses the two higest numbers of swap types (30 and 31).

CONFIG_MIGRATION is not set, no CONFIG_MIGRATION entry is in .config, so page migration was not compiled in. You also forgot to do "make oldconfig" when building the kernel. If you do a "make oldconfig" then your kernel will be build with page migration support.

It worked anywhere I tested up to and including the last one marked GOOD above. Anywhere below that was a mess. Backing out those two patches (and a bunch of dependant ones) seemed to make the problems we get very different, and if Martin is right the same as problems we are seeing on other architectures.

There is a crappy test in swap_on(). It should check against MAX_SWAPFILES and not do this conversion back and forth. Some architectures may not check if we are beyond the boundaries of what a swap entry can take. Why is this strange this in there? Are there architectures that support less than 32 swap devices?

Bligh, linux-kernel, ak, Hugh Dickins Sigh the patch that I sent earlier will make swapon fail when adding more entries if 32 entries have been defined before even if some of these are later freed. Plus maybe we better leave the probing intact for arches that support less than 32 swap devices and also return -EPERM like before. I guess we need this one instead: Do proper boundary checking in sys_swapon(). sys_swapon currently does not limit the number of swap devices. It may as a result overwrite memory following the swap_info array and get into entanglements with page migration since it may usethe swap types reserved for page migration.

So we get to keep the crappy test? Christoph's patch looks like it will fix the corruption to me (though I'd have thought the alternative below a little cleaner, keeping the associated tests together and avoiding a second unlock: whatever). Whether it's correct depends on what Martin was trying to achieve with his test. I'm surprised to find a very ordinary #define __swp_type(entry) (((entry).val >> 2) & 0x1f) in include/asm-s390/pgtable.h, and no architecture with a more limiting mask. I had expected that s390 (or some other) was short of bits and was having to use a more limiting mask: in which case neither Christoph's patch nor the one below would be appropriate, since the migration types 30 and 31 would then fall outside the mask (though it'd only be a problem if page migration were required on such an architecture). So, the patch should do for now, but it'd be helpful if Martin can explain why he needed to use that test in 2.6.5. (Perhaps he went through a phase of reducing the swap type and extending the swap offset, and this is a remnant of that phase?) > I wonder what LTP was corrupting before it started to corrupt page > migration data? > > The above looks like a 2.6.17 thing to me. Not really (though the clarity and reassurance of the additional MAX_SWAPFILES test is good). We went over it a year or two back, and the macro contortions do involve MAX_SWAPFILES_SHIFT: which up to and including 2.6.17 has enforced the MAX_SWAPFILES limit. But swapless migration has changed the relationship between MAX_SWAPFILES_SHIFT and MAX_SWAPFILES (-2 when CONFIG_MIGRATION), hence this corruption now surfacing in -mm.

At the same time on 31 bit systems only up to 4GB of swap is supported per device. That is because there are three reserved bits in the 31 bit pte, (pte & 0x80000900) must be zero. Bit 2^10 is the invalid bit, bit 2^9 the read-only bit. Two more bits are needed to distinguish between the different pte types. That makes 32-7 = 25 bits in total for offset and swap device. 5 bits are used for the swap device number, and 20 for the offset. I have chosen this split because for 31 the bit systems in 1999 the standard dasd device has been a model 3 with a capacity of 2.6 GB.

The idea has been that the creation of a swap entry with ~0UL as the type should mask off all bits that can not be represented in a swap entry.

Could we replace this expression with MAX_SWAPFILES? While we at it get rid of the "type" variable because we are usually using pointers to swap_info.

Well, if you want to go through all of swapfile.c, changing it over to use pointers rather than type/indexes.

I'll go mad if I try to work it out again: I was as worried as you when I discovered that test in sys_swapon a year or so ago, apparently without any check on MAX_SWAPFILES; and went moaning to Andrew. But once I'd worked through swp_type, pte_to_swp_entry, swp_entry_to_pte, swp_entry, I did come to the conclusion that the MAX_SWAPFILES bound was actually safely built in there. It's those four in swapops.h, and their concatenation in sys_swapon, that I meant by "macro contortions"; and I think they are safe (or were prior to swapless migration's -2), whatever the arch does for the __ones (which drive me even further insane).

Is it that complicated? You convert UINT_MAX as the type to a swap entry and back to a number. __swp_entry_to_pte() needs to do the correct masking. If it doesn't it is broken. The alternative would be to add architecture defines with the maximum number of swap devices and the maximum swap offset. -- blue skies, Martin.

Not everyone is as deficient as I am. But I do agree with you. I think Martin had good reason to do his "maxpages = swp_offset(....)" to work out the maximum pgoff expressible in an architecture's swap offset bits; but just went overboard in doing likewise with swap type. MAX_SWAPFILES and MAX_SWAPFILES_SHIFT are defined in the common include/linux/swap.h, and every architecture supports that many (some could manage more, but swp_type doesn't let them). If an architecture came along which somehow couldn't support that many (seems unlikely to me), then we'd move MAX_SWAPFILES_SHIFT into into arch-dependent files, wouldn't we? Yes, I'm all for sys_swapon just saying "if (type >= MAX_SWAPFILES)". Hugh ^ permalink raw reply [flat|nested] 179+ messages in thread

Oh, wasn't it rendered safe by the: Ok. So we have a mystical expression here that needs to be explained: swp_type(pte_to_swp_entry(swp_entry_to_pte(swp_entry(~0UL,0)))) swp_entry(~0L,0) -> swp_entry(0xffffffffffffffff, 0) -> 0xfffffffffffffff << SWP_TYPE_SHIFT -> 0x1f Ok we got the highest swap type and this encodes MAX_SWAPFILES_SHIFT and therefore limits the number of swap But now we convert this to a arch specific pte.

Thanks, Martin: we know very well that we cannot increase MAX_SWAPFILES without going through all the architectures adjusting their swap ptes (and maybe making MAX_SWAPFILES_SHIFT per-arch), so I don't see any problem there.

Martin, is the box still somewhat operational after such a crash? If yes then we could use my crash-tracer to see the kernel function call history leading up to the crash: http://redhat.com/~mingo/lockdep-patches/latency-tracing-lockdep.patch just apply the patch, accept the offered Kconfig defaults and it will be configured to do the trace-crashes thing. Reproduce the crash and save /proc/latency_trace - it contains the execution history leading up to the crash. (on the CPU that crashes) Should work on i386 and x86_64. the trace is saved upon the first crash or lockdep assert that occurs on the box. (but you'll have lockdep disabled, so it's the crash that matters) if the box dies after a crash then there's a possibility to print the execution history to the serial console - but that takes around 10-15 minutes even on 115200 baud. If you want/need to do this then edit kernel/latency.c and change "trace_print_at_crash = 0" to "trace_print_at_crash = 1". (btw., the tracer has another neat feature as well: if a kernel crashes or triple faults (and reboots) early during bootup, then the tracer can be configured to print all function calls to the serial console, via early_printk() - right when the function calls happen. I debugged numerous nasty boot-time bugs via this. To set it, change "print_functions = 0" to "print_functions = 1" in kernel/latency.c.)

Looks cool, but we'll have to beg the IBM guys to run it, I don't have access to that box anymore. Dumping to serial console would be cool, even if it's slow (the test boxes all have that logged).

The LTP output is here: http://test.kernel.org/abat/33803/debug/test.log.1 The last test run was memset01 From a good test run (http://test.kernel.org/abat/33964/debug/test.log.1) the one after memset01 is a second instance of the same. Which is bad I suppose, in that it's likely an intermittent failure. Perhaps you can try running memset01 in a loop? I don't have such a box set up here right now, I'm afraid ... will see what I can do. OTOH, it looks like this might be a different failure than the double fault we saw in previous -mm's, which was consistently in mtest01, IIRC.

Dont you disable DEBUG_SLAB?

Above is a good description of the problem - I really want to get as much debugging stuff done automatically as possible. However, we can have both. We just need to do both runs, with an option to turn whatever the random debug options of the day on or off are. Something that won't change over time. CONFIG_DEBUG itself would seem ideal, except it kills lots of standard things like CONFIG_DEBUG_INFO, alt+sysrq support, and probably KALLSYMS and a few other things I forget. Need CONFIG_DEBUG_AFFFECTS_PERFORMANCE or something. >>If we don't want to do performance regression checking on -mm, that's >>fine, but I thought it was useful (has caught several things already). > > please dont misunderstand my position as being against your efforts - to > the contrary, your performance regression testing has proven to be > valuable numerous times!

If we can get one option to flick off all the perf invasive stuff, that's a single change. If we have to add CONFIG_SLAB last week, CONFIG_DEBUG_MUTEX this week, and CONFIG_LOCK_DEBUG_STUFF next week, that gets much, much harder to maintain. Hopefully that makes some sort of sense. Sorry, I realise the requirements are a little strange, but I really think we have to get testing automated or it just does not happen. The last round affected Intel, etc as well doing benchmarking.

Changing the harness is hard ;-) ok. How about a CONFIG_DEBUG_NO_OVERHEAD option, that would default to disabled but which you could set to y. Then we could make all the more expensive debug options: default y if !CONFIG_DEBUG_NO_OVERHEAD this would still mean you'd have to turn off CONFIG_DEBUG_NO_OVERHEAD, but it would be automatically maintainable for you after that initial effort, and we'd be careful to always flag new debugging options with this flag, if they are expensive.

I don't care which way up it is, ie CONFIG_DEBUG_OVERHEAD vs CONFIG_DEBUG_NO_OVERHEAD, as long as it's easily separable. There's probably other debug stuff we can turn on too, if we do that.

It also gives us freedom to mark most of the transparent debugging options as default-enabled. i think i'll also do a DEBUG_KERNEL_ALLCHECKS flag that if set will select and enable all the transparent runtime checks. Often people just want to enable everything that still leaves us with a usable kernel, and filtering out those debug options can be a challenge.

It just didn't make much sense, a config option only to configure the default value of unseen values? If we have too many debug options, I don't mind to hide them behind an advanced config option, but their default values should not differ between their visible and hidden state, so that the user sees the real values when he enables the advanced option. A config option which only configures the default values is much less useful, in an already configured kernel it's completely useless to an user who only wants to enable some runtime checks and unless he reads the help text _carefully_, he might even think that he just enabled some runtime checks.

Did you read the discussion that lead up to it? I thought that quite clearly described why such a thing was needed. Config options need to clearly distinguish what they're for, or people will screw them up ... given: config DEBUG_RUNTIME_CHECKS bool "Enable runtime debug checks" config DEBUG_RUNTIME_CHECKS_ALL bool "Enable all runtime debug checks" depends on DEBUG_RUNTIME_CHECKS ... how is either the user meant to know under which of these to find things, or the coder introducing a new feature supposed to know where to put stuff? They're not very descriptive. Please can we have a more constructive discussion that "it's wrong, nack" ? M. ^ permalink raw reply [flat|nested] 179+ messages in thread

So the point is to enable the performance-affecting debug options by default, but provide one clear hook to turn them all off, with a name that's consistent over time, so we can do it in an automated fashion. To me that means having clear name so people know which option to hook stuff under, and preferably not hiding stuff behind extra config options to make them harder to find.

The latter is what Ingo's patch doesn't really do and the first should stay in -mm. If we talk about an -mm only patch we can relax the rules a little, my NACK was for mainline inclusion. The problem is that my request for a -mm only patch and other changes has been met with utter ignorance so far by Ingo. > To me that means having clear name so people know which option to hook > stuff under, and preferably not hiding stuff behind extra config options > to make them harder to find. Maybe I've missed the point of what you > were trying to do, but it seemed to not meet that. Well, if you don't want to enable a number of options, it's still better to hide them completely. There are number of options by reorganizing the debug menu a little, it only depends if we're talking here are about a -mm only crutch or something which might be useful to more than a handful of people. A few extra config options are not really a problem as long as they are logically grouped together (instead of having to enable random options all over the place). bye, Roman ^ permalink raw reply [flat|nested] 179+ messages in thread

How is the user meant to know which of your config options a particular option is hidden under? Same question for the developer as to where to put it? Seems there are two isses - whether the naming is meaningful or not, and whether you want to hide options under other options,or just flip defaults ... does that sound correct?

I don't quite understand where you want to go with this question. What do you consider an easy to find option? We have thousands of config options, they have to be organized somehow, so they are always hidden somewhere. Currently the debug menu is more a random collection of options, with a little organization it actually can make things easier to find, while still allowing a simple menu for the occasional user and an advanced menu. > Seems there are two isses - whether the naming is meaningful or not, > and whether you want to hide options under other options,or just flip > defaults ... does that sound correct? With my suggestion I was more concentrating on the latter (the general organisation of the menu options) than the actual wording. bye, Roman ^ permalink raw reply [flat|nested] 179+ messages in thread

As I mentioned before, please keep these defaults as a -mm-only patch, Giving them testing in -mm is fine, but defaults are already way too much abused as is. The default rule should be to enable an option explicitly, if it's needed, it should not be auto-enabled, because its author likes it so much. Using a "default y" should be close to hiding the option via CONFIG_EMBEDDED or some other option and the default should not differ between hidden and visible state, e.g.: config FOO bool "foo" if BAR default y bye, Roman ^ permalink raw reply [flat|nested] 179+ messages in thread

- The git-cfq tree is causing oopses and has been dropped.
- New reiser4 code drop.
- Merged the generic-IRQ handling code.
- Merged the runtime locking validator. If you enable this your machine
will run slowly.
- The build is broken on ia64 and probably on everything apart from x86,
x86_64 and powerpc. Check out the hot-fixes directory, as it won't be
broken for long.
- Dropped the git-viro-bid-* git trees - they're getting many rejects
against other things in -mm.
- Merged the new readahead code.
- Merged the generic statistics infrastructure patches.

For such nasty cases i have a kernel tracing patch prepared, you can get it from: http://redhat.com/~mingo/lockdep-patches/latency-tracing-lockdep.patch just apply it ontop of your current tree and accept all the new .config options as the kernel suggests them to you. Then rebuild and reboot into the kernel, and reproduce the lockdep bug. Once such a bug is reported, /proc/latency_trace should have a full kernel trace leading up to the bug. Please upload that trace to your site and send us the URL. (the tracer runs nonstop and it saves the current trace if it encounters a lockdep bug. That way i can see the history of the bug.) if possible it would be nice to boot with maxcpus=1 as well, to make sure we have all relevant kernel activity traced.

I haven't had a chance to look too closely, but the serial excerpt I have is below. The real BUG of interest is near the end with BUG: sleeping function called from invalid context at include/linux/rwsem.h:49 At the time of failure, a kernel compile was taking place. I've also seen one ppc machine (not ppc64) lock up. There was no output to console so it may or may not be related.

So there's no handler installed. yep. No desc->irq_handler. That should be 'impossible' on x86_64, because the irq_desc[] array is initialized with handle_bad_irq, and from that point on x86_64 only uses set_irq_chip_and_handler(), which at most can set it to another (non-NULL) handle_irq function.

Indeed (fixing ".irq_handler" to be ".handle_irq"), with that change MSI-X works fine with ib_mthca on my system. The only slightly funny quirk is that the IRQ type is shown as "PCI-MSI-X-<NULL>", I guess because it's printing handle_irq_name(NULL). However (as BenH pointed out) there's definitely some work to do to untangle MSI... - R. ^ permalink raw reply [flat|nested] 179+ messages in thread

I've been looking at the issues involved in supporting MSIs on various powerpc platforms and I came to the conclusion that there isn't a single re-useable line of code in there. Not only it's totally specific to a given set of intel chipsets, but it's also broken beyond imagination. I wonder how that code got in there in the first place, especially maskqueraded as "generic" code. Greg must have been drunk. At this point, the only solution for us (powerpc) is to allow the arch to have it's own implementatin of the toplevel MSI API (pci_enable_msi() etc...). From there, depending on what we come up with, we'll look into moving that back into generic code, but we are under some pressure for time (stupid 2 weeks merge window thing is a pain sometimes).

No, not drunk, just that no other arch offered up any potential help to get this working. So, we have one arch that has it working well, and finally, many years later when PPC64 catches up with the rest of the world, we have issues :) Feel free to help untangle it. ia64 just did a big chunk of work on this, and there are further patches in the -mm tree that help get it working there. ppc64 and other arch support are also welcome. You are the ones who know how your arch handles this stuff the best. > At this point, the only solution for us (powerpc) is to allow the arch > to have it's own implementatin of the toplevel MSI API (pci_enable_msi() > etc...).

Come on, just give it to me and let it sit in -mm for a while. I have some stuff in there for over 2 months before it goes to Linus to make sure that it's safe. You can do the same for your trees.

Also, this is a really hard case for lockdep to detect automatically. (fortunately it's also relatively rare) OTOH, the straightforward lockdep workaround would be to take the spinlock and thus disable all local interrupts - not too nice either. Albeit in some ways it's still a bit nicer conceptually than disabling the irq line, because other CPUs are still operational, and under certain locking designs [preempt-rt] spin_lock_irq() does not disable local interrupts.

I dont have this card. Until this popped up, I didn't know I had this card either ;) (the last time we dealt with this card was to help someone else) Anyway, I'll look into the way this card works and start to play with it when I get some time.

One technique could be to disable the IRQ on the card (i think the code already does this), and then call synchronize_irq() instead of disable_irq().

I agree that the trace is incomplete, but I'm not certain (without seeing at least twice as much of the raw stack) whether the unwinder is to blame here. After all, looking at the registers, the stack was already overflowed at the point the (nested) exception was taken, so there is no way to know whether the stack contents can actually be relied upon.

Could you try the patch below? Ingo ------------------------------------------------------ Subject: genirq MSI fixes From: Ingo Molnar <mingo@elte.hu> This is a fixed up and cleaned up replacement for genirq-msi-fixes.patch, which should solve the i386 4KSTACKS problem. I also added Ben's idea of pushing the __do_IRQ() check into generic_handle_irq(). I booted this with MSI enabled, but i only have MSI devices, not MSI-X devices. I'd still expect MSI-X to work now. irqchip migration helper: call __do_IRQ() if a descriptor is attached to an irqtype-style controller. This also fixes MSI-X IRQ handling on i386 and x86_64.
