[PATCH] D40047: AMDGPU/GCN: Remove xnack from 801 and 810

[Tony Tye via Phabricator via llvm-commits]

t-tye added a comment.

Took a look at the Mesa2D runtime with @kzhuravl  and it appears that the non-gfx names are being used, and xnack is being explicitly set using the target features. So this change should not have any impact on Mesa3d.

Did notice that for Mesa3D XNACK is being forcibly disabled for all targets <gfx9 and forcibly enabled for all targets >=gfx9. Is that the best choice? It seems it will likely not match how the driver is configuring the hardware. For example, how does the driver configure the APUs? Is XNACK always being enabled for gfx9 (it is not for compute)?
