Open-Source Radeon Performance Boosted By Linux 3.16

[dungeon]

This performance seems nearly get nulled by recent llvm changes .

Don't have time to bisect this, but it is somewhere in the last 20ish days between svn213451 and svn211669 .

What card and what test?

On low power Kabini (that is why maybe i can more easely spot any perf little regressions ) overall perf goes down by 5-7% when i compare those two mentioned llvm snapshots.

I will try now daily llvm, maybe only that snapshot regress slightly .

Nah the same with svn213730, but don't care much for now... i see some patches in mesa git which can reduce CPU overhead maybe better to test how that goes

With those performance goes up by 2-3% in Xonotic for example

Nah i must compile it again devs are so fast today, maybe i am hiting something like that

Yeah that is the fix for me .

Well... in the past when it froze I had nothing... and now I just get a D3 window about the crash, but I see nothing of interest in the command window.
Of course, I could be wrong and there could be something there I'm not seeing.

Well I might have been wrong after all.
Since 3.16 became stable, I thought I'd try again, but all I got was a computer crashing...
So I tried this time with a different card, and now it works fine (minus tearing in videos...).
Why? I'm not sure, maybe the previous card was defective? or the power cable I used for the previous one did not work somehow... I'll keep testing of course.
