Created attachment 107391 [details] [review] Make Mesa behave as if the kernel was older
(In reply to Andy Furniss from comment #3)
gallium hud on bad showing different vram gtt usage
That's very interesting indeed — on the 'good' screenshot, requested and actual VRAM usage match up almost perfectly, but on the 'bad' one, there's a large discrepancy.
With a current kernel, does the bad behaviour start with the same Mesa commit as the Unigine stutters?
I can't go back that far with Elemental due to llvm asserts.
The attached patch makes Mesa behave the same with current kernels as it does with older ones which don't have the bisected commit. Does that avoid the problem?
No, the patch makes no difference.
