i915 very high interrupt load

highlander34 · October 21, 2020, 11:40am

Opensuse 15.2 LXDE Desktop is installed on a Gigabyte B460D3H Board with Intel I3-10100 CPU, 16Gb Ram, 1 TB M3 SSD
Monitor is BENQ PD2705Q with Displayport Cable

when screensaver was active and desktop is unlocked, the system sometimes becomes very slow,
cpu load is constant high, desktop processes like firefox, konsole, scan tools become unusable slow.

cpu frequency is constanly at maximum for all 8 cores

I found that the i915 module processes a very high load of interrupts, more than 1 million/s
The list contains the data of /proc/cpuinfo and /proc/interrupts:


echo "$(date +%F-%T) $(awk '/MHz/ {printf "%9s ",$4}' /proc/cpuinfo) $(grep 'i915' /proc/interrupts)"

At 10:34 I reactivated the desktop, switched on the Monitor and unlocked the screensaver
The interrupt storm can be stopped only by reboot.

Is there a fix for this problem?
All updates are installed

dcurtisfra · October 22, 2020, 1:00pm

@highlander34:

Is the ‘i915’ kernel module properly installed? – “lsmod | grep -i ‘i915’”

Is all the “i915” firmware properly installed?

Does the content of “/lib/firmware/i915/” verify against the content of the “kernel-firmware” RPM package?

You may have to forcibly re-install the Kernel firmware package: “zypper install --force kernel-firmware” …

highlander34 · October 22, 2020, 3:26pm

the i915 module is loaded:

The system was reinstalled ar least 2 times and the problem showed up from the first install and with all kernel updates

I tried also some kernel boot i915.parameters like
i915.enable_dc=0 i915.enable_fbc=0 i915.reset=1 i915.disable_power_well=1 i915.verbose_state_checks=1 i915.enable_guc=2
in almost all combinations and values

with disabled display powersave mode the problem occurs less often, rest of system is never in powersave mode and running 24/7

If you are using the Intel DDX driver, try the (default) modesetting DDX driver; or vice versa. Some guidance on what this means, and how to implement a switch, can be found in this primer thread.

I3-10100 is Comet Lake (10th gen). Doesn’t it require i965 or an even newer intel kernel module for proper support? Maybe 15.2’s standard kernel isn’t new enough or hasn’t enough backports to support it properly.

dcurtisfra · October 23, 2020, 10:53am

“/usr/lib64/dri/i965_dri.so” is part of the “Mesa-dri” RPM package … – this ArchLinux thread: <https://bbs.archlinux.org/viewtopic.php?id=193563>.

Maybe, the X11 or Wayland environment needs to be checked to see if, the graphics are picking up the i965 driver …

highlander34 · October 23, 2020, 11:11am

I tested also the 5.4.71 kernel with same result, but I think it was also startet before the I3-10100 was released(?)

There is no “i965” in both kernels module dirs

openSUSE goofed with amdgpu while Fedora and Manjaro were fine: https://bugzilla.opensuse.org/show_bug.cgi?id=1177428 You may try to get a second opinion from these.

highlander34 · October 26, 2020, 2:26pm

The problem seems to be related to graphics powersave mode when monitor is turned off.

If monitor is turned on after gpu/video output is reactivated from powersave (by mouse or keyboard) the interrupt storm occurs very often.

I can try to change the DDX driver, but currently I am busy with other development and I thought hacking in the linux system is not required anymore today…

mrmazda · October 26, 2020, 10:26pm

I don’t consider reverting to the default DDX driver to be hacking. It’s newer technology than the drivers provided by xf86-video-* (yet more than 7 years old), which to me implies it should be enjoying more developer devotion. The reason the default doesn’t get used much has to do with maintaining support for antique and non-AMD/Intel/NVidia graphics, which the Modesetting DDX driver mostly doesn’t support. AFAICT, choosing the optimal DDX driver for antiques is too complicated for the Xorg automagic system.

highlander34 · October 27, 2020, 10:46am

All powersave and screensaver/lock was disabled, monitor was never turned off automaticaly and nothing was locked,
but I turned it off by power button yesterday evening and when i turned it on this morning the high interrupt load startet.

Bought a LG 24EB23PM-B back in 2014 and never experienced problems with the i3-4130 or the i7-6700K since then:

I switched the DDX driver by uninstalling the xorg-x11-driver-video and xf86-video-* packages as described in
https://forums.opensuse.org/showthread.php/541438-AMD-Intel-amp-NVidia-X-graphics-driver-primer

The problem did not change, but I found an easy way to reproduce the interrupt storm immediately:

No powersave, no screensaver, no mouse move or anything else.

Tested with BENQ PD2705 and Lenovo 24" Thinkvision, both connected with Displayport cable

I think the i915 module is broken and does not handle the new Intel 10100 CPU correctly, or maybe Gigabyte B460D3H board

karlmistelberger · October 28, 2020, 12:48pm

Guessing does not solve problems. Did you ever test with a live stick or another distribution?

BTW: The HP Laptop 15-da0xxx suspends/resumes without any issues even when an old fashioned LG TV is attached. But it chokes when NetworkManager is enabled.

I could not reproduce the interrupt problem on opensuse 42.3
at least not in the same way with monitor off/on as on 15.2

Suse 15.2 has also much more firmware for i915 than suse 42.3:

I removed the i915/kbl_dmc_ver1_04.bin file from the initrd and loading failed on boot,
but this changed nothing on the interrupt problem

Downgrade to kernel 4.4.240 or kick suse15.2 and return to 42.3?

When I encountered problems with i915 I moved forward to Tumbleweed: https://forums.opensuse.org/showthread.php/519529-Konsole-With-quot-su-quot-Freezing-The-System?highlight=i915 Backporting is slow and complicated. You may be better off using Tumbleweed. I never experienced trouble with i915 since 2016.

deano_ferrari · October 29, 2020, 10:11am

…or perhaps submit a bug report?

highlander34 · October 29, 2020, 10:36am

I have filed a bug report https://gitlab.freedesktop.org/drm/intel/-/issues/2609

should I create it here too?

Svyatko · November 5, 2020, 7:12pm

Yes.

And try to use new kernel + new firmware from Kernel:stable repo.
