<div style="font-family: Arial, sans-serif; font-size: 14px;">No worries Christian! I know everyone puts a lot of work in and stuff gets lost. I was mainly just firing the information into the ether in the hopes someone sees it and was like 'oh yeah' ;)<br></div><div style="font-family: Arial, sans-serif; font-size: 14px;"><br></div><div style="font-family: Arial, sans-serif; font-size: 14px;">I was running kernels 6.9-6.10. I havent hit it w/ 6.11 but thats likely because I havent been using my computer as much recently.<br></div><div style="font-family: Arial, sans-serif; font-size: 14px;"><br></div><div style="font-family: Arial, sans-serif; font-size: 14px;">I havent tracked down a cause. but usually I'm programming/gaming and watching a movie. so we have steam, a video game, vlc, firefox, sway, and vscode in the mix usually. I'm fairly certain its an application bug just don't which since I never only do one thing.</div><div style="font-family: Arial, sans-serif; font-size: 14px;"><br></div><div style="font-family: Arial, sans-serif; font-size: 14px;">I'm guessing that the misbehaving application is performing the command submission so rapidly due to not handling errors correctly its causing resource starvation leading the lock up and failure of oom to kick in if as your email asserts should occur.<br></div><div style="font-family: Arial, sans-serif; font-size: 14px;"><br></div>

Sorry for the delayed reply Without a maintainer in CC such

<div style="font-family: Arial, sans-serif; font-size: 14px;">recently
my system has been suffering from instability with the graphics
system. essentially some application on my system is causing oom
for graphics memory.</div>
<div style="font-family: Arial, sans-serif; font-size: 14px;">normally
I'd just expect a hard crash of the application in such a
scenario. instead the system enters a spin loop of command
submissions,</div>
<div style="font-family: Arial, sans-serif; font-size: 14px;">slows
down dramatically generally resulting in the system freezing up.<br>
</div>
<div style="font-family: Arial, sans-serif; font-size: 14px;"><br>

<div style="font-family: Arial, sans-serif; font-size: 14px;">There
are a couple issues I'd like to point out with the current
situation I'm experiencing:</div>
<div style="font-family: Arial, sans-serif; font-size: 14px;">
<ul data-editing-info="{"orderedStyleType":1,"unorderedStyleType":2}">
<li style="list-style-type: "- ";"><span>most
importantly the error message doesn't provide any useful
information for tracing the source of the issue. no pid,
or other diagnostic information.</span></li>
<li style="list-style-type: "- ";"><span>its very
noisy when trying to debug. I can occasionally drop my
system to a separate TTY and the message just spams the
entire screen. making it impossible to interact with my
system even if I wanted to load up debugging tools to
analyze the situation.</span></li>
</ul>
<div><br>
</div>
<div>given the error message I believe this line is the source
of the log statement.<br>
</div>
<div><code>[drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Not enough
memory for command submission!</code><br>
</div>
<div><span><a class="moz-txt-link-freetext" href="https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c#L1431" rel="noreferrer nofollow noopener" target="_blank">https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c#L1431</a></span><br>
</div>
</div>
<div style="font-family: Arial, sans-serif; font-size: 14px;"><br>
</div>
<div style="font-family: Arial, sans-serif; font-size: 14px;">Generally
I'm wondering if there is anything that can be done to improve
the experience for end users in such a scenario.</div>
<div style="font-family: Arial, sans-serif; font-size: 14px;"><br>
</div>
<div style="font-family: Arial, sans-serif; font-size: 14px;">Ideally
the system would nuke the misbehaving process similar to how ram
ooms are handled.</div>

<br>
If you see this message you should get the OOM killer running along
with it.<br>
<br>
If you don't see this then you probably run into a BUG or something
like that.<br>
<br>
What kernel version are you using and what did you do to trigger
that?<br>
<br>

<div style="font-family: Arial, sans-serif; font-size: 14px;">but
at a minimum I'd like to be able to figure out how to back track
this to the misbehaving process. any help in this regard would
be appreciated.<br>
