A Slew Of ACO Optimizations For The Radeon Vulkan Driver Landed In Mesa 20.0

[duby229]

Let's hope that AMD won't drop support for GFX6 in amdgpu anytime soon or these guys would need to wire up RADV also for radeon to enjoy the benefits of ACO on that hardware.

Personally I'd like to see ACO on RadeonSI this year with all the benefits it comes with. Would that be realistic or is this too much of a task for 2020?

Also wondering about ACO on Radeonsi...

I have difficulties even understanding what all those ACO commits mean, so I can't tell you how much work it is.

I *do* know however that ACO work appears to have recently started on GFX6 / Southern Islands chips, since there are 2 very recent merge requests containing multiple commits for GFX6 hardware:
https://gitlab.freedesktop.org/mesa/..._requests/3412 (this is GFX6 only work)
https://gitlab.freedesktop.org/mesa/..._requests/3407 (this was already merged and is a fix for GFX6 and GFX7)

The branch for the first merge request is called "gfx6_first_round", so it sounds like that was the first round of commits, specific to getting GFX6 working, to be included in mesa.

There's also this branch called "aco_gfx6_support" that seems to be the WIP branch where development happens: https://gitlab.freedesktop.org/hakzs...o_gfx6_support

So I guess anything from "a couple of weeks" up to "a couple of months" or maybe even longer is possible. It's reassuring to see this development taking place though. :-)

GFX6 support should be in Mesa 20.0:

Oh, thanks for pointing that out to me!
That's a very welcome surprise. So that's why Samuel Pitoiset is apparently working long hours to get this in shape quickly :-) I hope he can find some time to relax once they have made the 20.0 deadline!
