acpi idle gpf? *** Bug 108768 has been marked as a duplicate of this bug. *** *** Bug 108864 has been marked as a duplicate of this bug. *** Last seen this issue CI_DRM_5236_full (1 day, 22 hours / 5 runs ago). https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_5236/shard-iclb6/igt@pm_rpm@cursor-dpms.html One more instance https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_168/fi-icl-u3/igt@pm_rpm@debugfs-read.html (In reply to Lakshmi from comment #5) > One more instance > https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_168/fi-icl-u3/ > igt@pm_rpm@debugfs-read.html It seems i am able to reproduce the issue multiple times, but not able to get the page fault crash dmesg log, my system is resetting even before printing any dmesg log, So not sure if crash is same as page fault in acpi idle. As i see acpi idle gpf crash logs are available for CI_DRM_5180 and CI_DRM_5184. From where i can get the vmlinux kernel object file and System.map file for CI_DRM_5180 and CI_DRM_5184. It will helpful to debug the page fault in acpi_idle_enter code. (In reply to Lakshmi from comment #5) > One more instance > https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_168/fi-icl-u3/ > igt@pm_rpm@debugfs-read.html ICL CPU id family patches are not merged to up streamed mainline kernel, due to that ICL H/W still using ACPI idle driver, This ACPI idle page fault will not be there with intel_idle driver, this issue should be fixed once ICL CPU id patches will be public.

This crash is different from earlier crashes, earlier crashes were in to acpi idle driver, but this is different one. Looks a different bug to me.

Anshuman, are there any changes done recently to address this bug? Last seen drmtip_244 (5 days, 11 hours / 87 runs ago)on fi-icl-y. If not fi-icl-y, last seen on shards IGT_4878_full (1 week, 6 days / 168 runs ago). Update: Anshuman will try to reproduce this issue with latest BIOS to get more information about his issue. Seems like the common denominator is that i915_gem_wait_for_idle() hangs (or never completes), which triggers a hang, which reboots the machine because CI sets panic=1. There is an assumption that a page fault happening in the ACPI idle driver might be responsible for this, but I'm CC:ing Francesco to verify that the logic is sound with his engineers, while waiting for the ACPI driver fixes to be ready and landed in Linux.

We ran the test on our local setup with latest drm tip and latest BIOS V3121. i915_pm_rpm doesn't complete and there is hard lockup after running igt subtest "gem-execbuf-stress" there is hard lock up.

Who is a taker? patch is ready, if we disable ACPI idle driver, there is no idle driver available for ICL, so as consequence of it cpu idle also gets disabled completely. As it is a hack, is it ok to send this patch to Intel-gfx <intelgfx-@lists.freedesktop.org> ? BIOS was updated on ICL-U3.

Yes, please explain why you are doing this, and that this is for the core-for-CI, and ICL-only.

Wysocki: This is fine only as long as it doesn't anywhere close to the mainline. If ACPI idle crashes on new Intel HW, it needs to be fixed to work with it instead of refusing to work on it.

This failure is still happening on drmtip and shard runs. Reopening this bug. Needs further investigation. I have checked logs of CI Bug Log , from recent logs, All of these recent issues are not having any pstore crashes logs. So it is hard to state that if it is a similar or different issue. I can only see the same issue pattern (i915_gem_wait_for_idle timeout) to 3 weeks older issue on CI_DRM_5960_full with below details from CI Bug Log. IGT: igt@i915_pm_rpm@universal-planes-dpms shard-iclb5 IGT: incomplete (external URL) CI_DRM_5960_full (3 weeks, 2 days old) None for the issue, None for the filter Issue: fdo#108840 - [CI][BAT] igt@*pm_rpm@* - incomplete - ICL: igt@*pm_rpm@* - incomplete @Lakshmi please assign this to Gem Core side. (In reply to Anshuman Gupta from comment #37) > @Lakshmi please assign this to Gem Core side. Why? There's nothing here to debug, and less to connect it to GEM itself. Tried local reproduction (we found same pattern that i915_gem_idle_thread hung).
And it all started from stall CPU and possibly due to that kwroker is hunged and system is in panic ( see below INFO: task kworker/2:1:62 blocked for more than 61 seconds.).

Jani S. asked me to drop 99b69db57544 ("ICL HACK: Disable ACPI idle driver") from topic/core-for-CI. But there seems to be some conflicting views here. Chris? (In reply to Jani Nikula from comment #40) > Chris? It's getting stuck inside the vblank interrupt handling code. So we are not switching off hw correctly for rpm, or not waking up correctly? I'm not sure what's going on here, but at least the log above is not particularly useful since it has vblank debugs on (meaning a lot of printks) and it seems to also have serial console enabled (which is slow). That particular combination is not a great idea. http://gfx-ci.fi.intel.com/cibuglog-ng/issue/929 CI bug log indicate new failures of this bug but most of time there are no pstore logs. This makes to suspect if it could be e1000e hang which i mentioned earlier in comment 23, we see a hang in e1000e module on our DUT after running i915_pm_rpm hibernation and system-supend test. Due to e1000e hang we lost network ssh console but DUT was actually running, it was not a crash but DUR stop responding on network. Can we try running i915_pm_rpm test after blacklisting e1000e module?

We cannot blacklist the module of our network card :D But I guess we'll need to try using some USB network cards and see if this decreases the reproduction rate. Tomi will be servicing the shards next week, we'll make sure he uses the USB adapters as much as possible! Actually, aren't we using always USB network dongles on ICL? I think we are. Yes. RVPs generally have e1000e with unflashable identical MAC addresses 88:87:... so it's least hassle to use USB dongles for them. This also helps with the HW issues of e1000e. e1000e driver doesn't need to be loaded on RVPs, but no extra blacklisting is done either to keep the "user" defaults. Dropping priority as developer cannot reproduce.
