Well, the resolutions may be trivial, but the conflict made me look at the code, and it's buggy. Commit 04d8d73dbcbe ("drm/amdgpu: add common HMM get pages function") is broken. It made the code do mmap_read_lock(mm); vma = find_vma(mm, start); mmap_read_unlock(mm); and then it *uses* that "vma" after it has dropped the lock. That's a big no-no - once you've dropped the lock, the vma contents simply aren't reliable any more. That mapping could now be unmapped and removed at any time. Now, the conflict actually made one of the uses go away (switching to vma_lookup() means that the subsequent code no longer needs to look at "vm_start" to verify we're actually _inside_ the vma), but it still checks for vma->vm_file afterwards. So those locking changes in commit 04d8d73dbcbe are completely bogus. I tried to fix up that bug while handling the conflict, but who knows what else similar is going on elsewhere. So I would ask people to (a) verify that I didn't make things worse as I fixed things up (note how I had to change the last argument to amdgpu_hmm_range_get_pages() from false to true etc). (b) go and look at their vma lookup code: you can't just look up a vma under the lock, and then drop the lock, and then think things stay stable. In particular for that (b) case: it is *NOT* enough to look up vma->vm_file inside the lock and cache that. No - if the test is about "no backing file before looking up pages", then you have to *keep* holding the lock until after you've actually looked up the pages! Because otherwise any test for "vma->vm_file" is entirely pointless, for the same reason it's buggy to even look at it after dropping the lock: because once you've dropped the lock, the thing you just tested for might not be true any more. So no, it's not valid to do bool has_file = vma && vma->vm_file; and then drop the lock, because you don't use 'vma' any more as a pointer, and then use 'has_file' outside the lock. Because after you've dropped the lock, 'has_file' is now meaningless. So it's not just about "you can't look at vma->vm_file after dropping the lock". It's more fundamental than that. Any *decision* you make based on the vma is entirely pointless and moot after the lock is dropped! Did I fix it up correctly? Who knows. The code makes more sense to me now and seems valid. But I really *really* want to stress how locking is important. You also can't just unlock in the middle of an operation - even if you then take the lock *again* later (as amdgpu_hmm_range_get_pages() then did), the fact that you unlocked in the middle means that all the earlier tests you did are simply no longer valid when you re-take the lock.

But I really *really* want to stress how locking > is important. Thank you for the fix and the explanation. Your fix looks correct. I also double-checked all other uses of find_vma in the amdgpu driver. They all hold the mmap lock correctly. Two comments: With this fix, we could remove the bool mmap_locked parameter from amdgpu_hmm_range_get_pages because it always gets called with the lock held now. You're now holding the mmap lock from the vma_lookup until hmm_range_fault is done. This ensures that the result of the vma->vm_file check remains valid. This was broken even before our commit 04d8d73dbcbe ("drm/amdgpu: add common HMM get pages function"). > > You also can't just unlock in the middle of an operation - even if you > then take the lock *again* later (as amdgpu_hmm_range_get_pages() then > did), the fact that you unlocked in the middle means that all the > earlier tests you did are simply no longer valid when you re-take the > lock. I agree completely. I catch a lot of locking bugs in code review. I probably missed this one because I wasn't paying enough attention to what was being protected by the mmap_read_lock in this case.

You can find the full serial console output at: https://t.zekjur.net/linux-5.14-raspberry-pi-3-hang-vc4.txt The last few messages are from vc4, then the boot hangs. Using git-bisect, I tracked this down to https://github.com/torvalds/linux/commit/e058a84bfddc42ba356a2316f2cf1141974625c9, which is the merge you’re talking about here, AFAICT. I also tried the git://anongit.freedesktop.org/drm/drm, and that tree boots as expected, suggesting that the problem really is with the additional changes. The code seems to work on my Raspberry Pi 4, just not on the Raspberry Pi 3. Any ideas why that might be, and how to fix it? Thanks!

Ok, that's a different merge issue than the locking one (which is about the amd ttm code). But the VC4 driver did have changes close to each other in the hdmi detection and clock setting code. And it doesn't seem to be just RPi3, there was a report back a couple of weeks ago about RPi4 also having regressed (with an Ubuntu install). That one was an oops in vc4_hdmi_audio_prepare(). I don't know if that got resolved, I heard nothing about it after the report. So there's something seriously wrong in VC4 space. The main issue seems to be the runtime power management changes. As far as I can tell, the commits that didn't come in through that drm pull were these two 9984d6664ce9 ("drm/vc4: hdmi: Make sure the controller is powered in detect") 411efa18e4b0 ("drm/vc4: hdmi: Move the HSM clock enable to runtime_pm") Michael - do things work if you revert those two (sadly, they don't revert cleanly exactly _because_ of the other changes in the same area)? Maxime? Linus

Reverting only 9984d6664ce9 is not sufficient, but reverting both 9984d6664ce9 and 411efa18e4b0 does indeed make my Raspberry Pi 3 boot again! Thanks for identifying the faulty commits.

This was from last night - https://lava.qa.codethink.co.uk/scheduler/job/164#L1356 Last night's test was on top of 4357f03d6611 ("Merge tag 'pm-5.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm")

Since you did those reverts and fixed up the conflicts, would you mind sending out the resulting patch so that maybe Sudip can test it too? Maybe the RPi4 hdmi audio issues are related to the RPi4 hdmi problems despite the symptoms apparently being rather different.. Linus

Looks like a DNS issue with the subdomains, someone else also reported the same last week. I have reported this to our ops and they are looking into it. Also, I have now tested by reverting those two commits and I still get the same trace on rpi4. Copying here again for your reference.

I'm afraid we really need to have the VC4 people figure it out - I count do the two reverts that are reported to fix the RPi3 issue, but it looks like the RPi4 pulseaudio issue needs something else. Any chance you could bisect that? Actually, looking at that first report of yours, the RPi4 sound problem apparently happened in the range 9e9fb7655ed5..7c636d4d20f8 and while that range does have a drm merge from Dave Airlie, it _also_ has a sound merge from Takashi and various ARM SoC updates from Arnd. But most (all?) of the changes in that range to the vc4 source code came from the drm tree. And Maxime in particular. I think. Linus

Ok, since your pulseaudio problem was reported already over two weeks ago with no apparent movement, I've done that revert in my tree. I reverted the two runtime PM changes that cause problems for Michael too. Linus

Any ideas why that might be, and how to fix it? I assume you run your Pi without anything connected on HDMI, and without hdmi_force_hotplug in your config.txt? If so, can you test that branch, and let me know if it works for you https://github.com/mripard/linux/tree/rpi/bug-fixes Maxime

I'm sorry, but I find that situation to be a bit ridiculous. In order to be properly addressed, Michael's issue needs some patches that have been unreviewed for 5 monthes now. However, if one reports an issue to you, without cc'ing the author, on a week-end, the revert is done in a single day. Even that audio bug only got a proper report yesterday, after you asked for it. Do you really expect us to work during the week end too? Maxime

Apologies if I have missed any of your mail, but iirc you have only asked me what tests I am running, but Linus asked if I can do a bisect. -- Regards Sudip

Honestly, the original report about the pulseaudio problem came in over two weeks ago, and all you seemed to do was to ignore everything that Sudip said and reported. THAT is the ridiculous part. The rules for the kernel are very clear: regressions get fixed or they get reverted. And I saw absolutely _zero_ indication that you took that pulseaudio oops at all seriously. Linus

What I was interested in was more about the context itself, and I'd still like an answer on whether it's ok to wait for a review for 5 months though, or if it's an expectation from now on that we are supposed to fix bugs over the week-end.

Oh, it's definitely not "over a weekend". These reverts happened on a Sunday just because that's when I do rc releases, and this was one of those pending issues that had been around long enough that I went "ok, I'm reverting now since it's been bisected and verified". So it happened on a weekend, but that's pretty incidental. You should not wait for 5 months to send bug-fixes. That's not the point of review, and review shouldn't hold up reported regressions of existing code. That's just basic _testing_ - either the fix should be applied, or - if the fix is too invasive or too ugly - the problematic source of the regression should be reverted. Review should be about new code, it shouldn't be holding up "there's a bug report, here's the obvious fix". And for something like a NULL pointer dereference, there really should generally be an "obvious fix". Of course, a corollary to that "fixes are different from new development", though, is that bug fixes need to be kept separate from new code - just so that they _can_ be handled separately and so that you could have sent Sudip (and Michael, although that was apparently a very different bug, and the report came in later) a "can you test this fix" kind of thing. I don't know what the review issue on the vc4 drm side is, but I suspect that the vc4 people are just perhaps not as integrated with a lot of the other core drm people. Or maybe review of new features are held off because there are bug reports on the old code. Linus

I still don't have a way to reproduce Sudip's bug, so I can't even provide that. > I don't know what the review issue on the vc4 drm side is, but I > suspect that the vc4 people are just perhaps not as integrated with a > lot of the other core drm people.

Hi Linus, This is the main drm pull request for 5.14-rc1. I've done a test pull into your current tree, and hit two conflicts (one in vc4, one in amdgpu), both seem pretty trivial, the amdgpu one is recent and sfr sent out a resolution for it today. Not much outside the tree, one x86 early quirk patch, and dma_resv renamed some APIs that had changes in other drivers. Highlights: - AMD enables two more GPUs, with resulting header files - i915 has started to move to TTM for discrete GPU and enable DG1 discrete GPU support (not by default yet) - new HyperV drm driver - vmwgfx adds arm64 support - TTM refactoring ongoing - 16bpc display support for AMD hw Otherwise it's just the usual insane amounts of work all over the place in lots of drivers and the core, as mostly summarised below.
