Re: i915 Skylake GPU hangs with kernel 5.3.11

@atwalter What if you use the latest commit from drm-tip?

I have GPU hangs with 5.7-rc too. The situation is even worse comparing to 5.5.7 which I'm currently using. I tried modesetting, but unfortunately mpv plays video with tearing in this case. I also noticed that GPU hangs are mostly caused by qutebrowser (chrome-based). So I disabled GPU HW acceleration in qutebrowser and after that I haven't seen any hang so far.

Looks like the saga continues...

Try not to empty post: https://wiki.archlinux.org/index.php/Co … mpty_posts If you have something constructive and additional to add, add that with information pertaining to the problem.

@kldloadsndhda
Tearing issues with the modesetting driver are fixable with a compositor, if you can use the system as normal without basically disabling active GPU usage when using the modesetting driver, then we have likely found a bug in xf86-video-intel that should be reported there.

@V1del
Thanks, I tried compton and picom but they didn't help, I still observed tearing issues with them. Sorry, I will keep using xf86-video-intel.

Re: i915 Skylake GPU hangs with kernel 5.3.11

@loqs Still getting kernel panics on drm-tip commit `73b76d6b` (from May 2)

Recently kernel panics have stopped being logged (at least in the output of journalctl), gonna try to set up kdump to capture output.

FWIW Firefox has also been causing me problems after the reinstall, especially when using the BlueJeans video conferencing tool from the browser. Might try to disable hardware acceleration and see if that helps anything.

Re: i915 Skylake GPU hangs with kernel 5.3.11

I found the following i915 module options, gave me a rather stable system on kernel 5.6.3, I have hw acceleration in both chrome and firefox, blacklist disabled. I used to have pretty frequent hangs; Now this options has been stable for me for more than a week.

options i915 enable_psr=1
options i915 enable_guc=2
options i915 nuclear_pageflip=Y
options i915 enable_dc=2

I'm using a Dell Precision 7510, i7-6920HQ, Intel 530, xf86-video-intel driver.

Re: i915 Skylake GPU hangs with kernel 5.3.11

I'm getting GPU hangs multiple times per day on 5.6.12 with an XPS 13 9300. Seems to happen in Intellij IDEA, but it's hard to predict. CPU load is low and memory load is average.

Here's the dump:

Re: i915 Skylake GPU hangs with kernel 5.3.11

I'm still hang-free using drm-tip version 5.7.905208.d0fda5c2cf3f-1 - the version I posted links for on the previous page. However, I have not been able to update from this version. All newer builds hang on boot. I can get past the grub menu, but after the loading initrd message, nothing. This has become an issue because I need virtualbox and the working kernel version is incompatible with vboxhost. Apparently the issue there is neither the kernel nor vboxhost because vbox 6.1.6 was working, but stopped working after the latest gcc upgrade, as far as I can tell). The latest drm-tip build does build the vboxhost module without error, but... it doesn;t boot. Any ideas on why the latest build might not be booting?

Re: i915 Skylake GPU hangs with kernel 5.3.11

Most likely gcc10 issue would be drm-tip not havinig https://git.kernel.org/pub/scm/linux/ke … b92c7c1e7e as it has not back-merged 5.6-rc6

Re: i915 Skylake GPU hangs with kernel 5.3.11

@loqs Great. Guess I'll have to wait. Looks like it was committed 3 days ago. Thanks for the reference, bud.

Edit: well, actually it's there in 5.7-rc6. guess i'll try another drm-tip build...
Edit2: not in drm-tip yet - still on 5.7-rc5. i'll give it another day or two to catch up.

Re: i915 Skylake GPU hangs with kernel 5.3.11

You could try the following to manually cherry-pick the commit

makepkg -Co
cd src/linux-drm-tip-git
git remote add origin https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
git fetch origin
git cherry-pick -n a9a3ed1eff3601b63aea4fb462d8b3b92c7c1e7e
cd ../..
makepkg -e

Or you could add the calls to the prepare function of the PKGBUILD on any line after scripts/setlocalversion --save-scmversion
Edit:
Missed adding origin repository first.

Re: i915 Skylake GPU hangs with kernel 5.3.11

@loqs thanks much for posting that. i'll stash that away for future reference.

the gcc10 boot fix was merged into drm-tip pretty much the next day, but now the issue is a build error that isn;t going away:

  CC [M]  drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.o
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c: In function ‘amdgpu_amdkfd_gpuvm_free_memory_of_gpu’:
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c:1357:2: error: implicit declaration of function ‘drm_gem_object_put_unlocked’; did you mean ‘drm_gem_object_put_locked’? [-Werror=implicit-function-declaration]
 1357 |  drm_gem_object_put_unlocked(&mem->bo->tbo.base);
      |  ^~~~~~~~~~~~~~~~~~~~~~~~~~~
      |  drm_gem_object_put_locked
cc1: some warnings being treated as errors

i've been pushing the package maintainer to look into it, but not getting any traction. i have to assume that the devs must be doing periodic builds to test their merges and can't understand why this wouldn;t have been caught and fixed by now.

so, i've temporarily downgraded gcc to 9.3 and the vboxhost dkms module now builds into my existing drm-tip 5.7-rc1 kernel without any errors. but... now i have to wonder when that downgrade is going to bite me in some other way - like when something built with gcc10 barfs up when it can;t find the gcc10 libraries...

Re: i915 Skylake GPU hangs with kernel 5.3.11

An alternative workaround might be to disable CONFIG_DRM_AMDGPU in .config so amdgpu is not built.  Or you could clean chroot build with gcc 9.3.

https://kernelci.org/ look to be mostly using gcc 8.3.
https://intel-gfx-ci.01.org/ I could not find as easily a toolchain.  From https://gitlab.freedesktop.org/drm/intel/-/issues/1899 which was a recently filed CI bug has this test summary https://intel-gfx-ci.01.org/tree/drm-ti … 5-psr.html and from https://intel-gfx-ci.01.org/tree/drm-ti … boot17.txt

<5>[    0.000000] Linux version 5.7.0-rc5-CI-CI_DRM_8490+ (cidrm@ci-worker1.fi.intel.com) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04), GNU ld (GNU Binutils for Ubuntu) 2.30) #1 SMP PREEMPT Fri May 15 23:50:52 EEST 2020

Edit:
Did the drm-tip that failed with gcc 10 build with 9.3?
https://cgit.freedesktop.org/drm-tip/co … 91229bc654
https://cgit.freedesktop.org/drm-tip/co … 8538fa0bb0
drm_gem_object_put_unlocked is renamed to  drm_gem_object_put but the second commit updating amdgpu did not change amdgpu_amdkfd_gpuvm.c possibly because https://cgit.freedesktop.org/drm-tip/co … 126add6b66 was merged to drm-tip between the name-change being developed and being merged.  Can you build with fd9a9f8801def3908960312e46bb92126add6b66 reverted?

Re: i915 Skylake GPU hangs with kernel 5.3.11

@loqs thanks. i ended up commenting out CONFIG_DRM_AMDGPU in the config file. that got me a working kernel. the build failure has still not been resolved but it comes down to a single source file - drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c. the problem goes back to a series of source changes that were made, changing drm_gem_object_put_unlocked/locked to drm_gem_object_put. apparently, they missed one source file. i've created a bug report for it at https://gitlab.freedesktop.org/drm/amd/-/issues/1156.

the workaround is to use the following patch, which i've named 001-amdkfd-drm_gem_object_put_unlocked.patch:

--- a/drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c  2020-05-30 10:34:11.738183991 -0400
+++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c  2020-05-30 16:01:12.296946979 -0400
@@ -1354,7 +1354,7 @@
        }

        /* Free the BO*/
-       drm_gem_object_put_unlocked(&mem->bo->tbo.base);
+       drm_gem_object_put(&mem->bo->tbo.base);
        mutex_destroy(&mem->lock);
        kfree(mem);

one just has to add the patch file to the top-level directory (where the PKGBUILD is located) and add the patch file name to the PKGBUILD's list of source files. the PKGBUILD has a logic block that applies any .patch (dot-patch) file(s) it finds in src. btw, 5.7 is still working to resolve the intel freeze. cheers.

Edit: fyi, i've moved back to the mainline core 5.7 kernel again now. been using it for several days and have not experienced any graphics freezing or module crashes.
