Disabling Intel Graphics Security Mitigations Can Boost GPU Compute Performance By 20%

The common sketchy performance advice is to disable mitigations in the kernel, this post is about disabling mitigations in Intel's userspace graphics stack because it's already checked in the kernel.

Assuming you meant disabling kernel mitigations, since AFAIK audio stuff doesn't usually use OpenCL:

Has anyone else here disabled it?

Nah, my understanding is it's not worth it on newer CPUs, and in some cases, the microcode expects things to be mitigated for best performance. Older CPUs (pre-2019ish) it does make a difference though.

But you're welcome to benchmark it, and see if it makes a worthwhile difference on your CPU. Kernel mitigations are easy enough to turn on and off.

Why am I cross-posting .ml?

I cross-post from .ml to the nearest relevant non-.ml comm to reduce the influence of .ml comms and indirectly, the instance as a whole, to make it an easier decision for other instance admins to defederate because one key reason I identified that admins don't want to defederate is because .ml still has some very large comms and some niche comms.

Megathread on the issue

Some highlights from the link:

"Don't worry guys, the Uyghur Genocide was REALLY just birth control! ~dessalines, .ml admin, dev https://lemmy.world/post/30580167

"See! nobody died IN Tiananmen Square, just AROUND it, so it doesn't count!!" ~ Davel, .ml admin https://lemmy.world/post/30673342

.ml admin, Nutomics continued transphobia https://lemmy.world/post/29222558

CW: Original transphobic Comment from Nutomic

And so so much documentation on clear heavy handed censorship and bias also on the link. So much I can't even put them all here because this comment would be really long.

I believe the behavior of its admins (the main admins are Lemmy devs) does harm to the overall growth of the Lemmy-verse and maybe even the Thrediverse (since Lemmy kinda kicked off the Thrediverse) because of its association with the devs of Lemmy and their insistence to use .ml as their personal political platform to spread harmful propaganda

On the outside, bringing up Lemmy frequently leads to comments like "Lemmy? Isn't that the place with a bunch of tankies?" Or "Tried Lemmy, but found it full of pro Russia crap so I left". The best way forward from that I see is to either widely defederate from .ml like the rest of the Triad, or pressure them to put a fair and unbiased as possible admin team.
