Apparently fix Kaveri A10 7850K did not touch the RADV driver. I did a benchmark in the game Rise of the Tomb Raider before and after the fix, and FPS remained the same. Despite the fact that the fixed yields of approximately 50%.
P.S.Mesa RADV 18.2.6, linux kernel 4.19.8
I'm sorry but I don't understand what your report means.
What are you talking about? And what fix?
Have 7850К earlier, it was stated the wrong number of render backends.
This should have been fixed in the new kernel version and Mesa 18.2, respectively. But in RADV, I'm seeing old performance.
This code is shared by RadeonSI and RADV, so I assume that commit should also help RADV.
I also think. But I measured the FPS before and after the Mesa and kernel update.
Note that the patch is a theoretical 2x benefit in a very specific case.
Do you have a GL game where there is a significant difference? Otherwise I'd assume this is just a specific bottleneck that is not hit a lot in practice and hence would not typically result in significant performance changes.
GL games are not compared, only Vulkan. Because there is a suspicion that the patch is not touched RADV.
Unless you have numbers that for GL it actually improves performance for some implications I'm not going to spend time on this.
OK. Then close.
Hopefully pay attention to another important bug report.
More precisely this, sorry.
