Hi All, So this patch, which I already submitted a while ago and back then it got one comment from Chris Wilson: > Basically you want a limit on the frequency of ... pcode access? > As presented, you ultimately do not trust any write and the only > solution is to disable all writes. No RPS whatsoever, run at max and > hope rc6 works (maybe even decrease the rc6 threshold). > > One of the ideas we floated was moving the pcode access to a worker and > ratelimiting the updates. Has finally seen some testing by users affected by the infamous "intel_idle.max_cstate=1 required to prevent crashes" bug: https://bugzilla.kernel.org/show_bug.cgi?id=109051 And so far the reports are that it does help to make the users stable for 2/3 users and it not being effective for 1/3 users. Now that we've some test results, I believe that it is worthwhile to get this simple patch mainlined, hence this re-submission.
