@timojyrinki I use only LKML if I decide to post anything. I hate bug trackers, sorry :-) it is a kernel bug so LKML is way to go. Going to ignore web forms for sure.

GPU HANG is emitted by error_msg. Would be better of by being i915_error_msg or i915_error for easier grepping and inserting probes and this also supports it:

$ git grep error_msg|wc -l

@timojyrinki unrelated side-note, i don’t undestand why people put this cruft to new code in kernel:

 * Authors:
 *    Eric Anholt <eric@anholt.net>
 *    Keith Packard <keithp@keithp.com>
 *    Mika Kuoppala <mika.kuoppala@intel.com>

Nobody cares as Git has author field. Totally useless information.

@timojyrinki yeah, i'll start to grep kernel tree, and see where the messages emit.

@timojyrinki ya, switching to AMD is not an option ;-) And as said CPU has caused zero issues so far. Not like by ideology but do not want to spend moneyz.

Still a major turndown, i.e. owning a GPU that cannot do graphics.

@timojyrinki i'm happy intel alumni but unhappy intel customer :-) does not match my quality expectations tbh.

@timojyrinki let me remind that this happens neither with RTX nor with CPU heavy tasks such as compilation.

another different kind of workload where this does not happen is Bitwig Studio. So this is directly connected to this graphics card way or another.

I disabled upscaling (i.e. intel_pstate) but have not yet tried also disabling downscaling, which could be good test perhaps.

@jani you know how fix or workaround this? :-) Never happened with same machine only exception being NVIDIA RTX card instead of Intel. Has been ongoing issue for half years but I have had neither time nor interest to play anything that much so have ignored it so far.

The irony is that I bought Intel card exactly for better "out-of-the-box" state for system after installing OS ;-)

I get something like this constantly with Steam:

[38438.072899] x86/split lock detection: #AC: ChaosGate.exe/11646 took a split_lock trap at address: 0x6fffe5f51242
[38441.268772] x86/split lock detection: #AC: ChaosGate.exe/11852 took a split_lock trap at address: 0x6ffff6801001
[38446.628277] x86/split lock detection: #AC: Loading.Preload/11762 took a split_lock trap at address: 0x6ffff6a3aee0
[38494.104580] i915 0000:03:00.0: [drm] GPU HANG: ecode 12:1:84dfd7f7, in ChaosGate.exe [11646]
[38494.104588] i915 0000:03:00.0: [drm] ChaosGate.exe[11646] context reset due to GPU hang

Any ideas? This is now KDE6/X11 but the similar hang happens also with Wayland.

CPU is i9-13900k, GPU is ARC A770 and OS is Tumbleweed. Kernel is latest mainline but this has happened also few previous kernel versions.

Also this seems to happen with any possible game but all of them are Windows games running with Proton.

thanks! i'll check it out. however, would be nice if simply by cloning buildroot and selecting "external toolchain" it would just work :-)

@troglobit ya, it is not like a dev machine of any kind but still would be nice to have the toolchain for occasional use :-)

@oherrala always dreamed of having that, and some games are really good, i have bunch of them for my MiSTeR FPGA :-)

@troglobit binaries are for x86 despite there is target for aarch64. i.e. host is x86 and target is aarch64. i'd like also have in addition that to have compilers for different targets where host is aarch64. i.e. they are x86 hosted.

for instance i have x86 PC's and Mac Mini. Sometimes I'd like to use a VM in that mac mini to run bootlin toolchains. and e.g. in buildroot config i rarely use "external tooclhain" option because it is not portable with the machine architectures i have.

Love #bootlin toolchains but wish there was also #aarch64 hosted versions of each :-) https://toolchains.bootlin.com/
