[PATCH] D39350: AMDGPU: Add CPUCoherentL2 feature

[Tony Tye via Phabricator via llvm-commits]

t-tye added a comment.

Are we sure using SLC is the way to achieve this? IIRC SLC can be used for streaming, but does not ensure L2 bypass. On an APU the MTYPE=CC specifies the memory policy that support coherence.
