I split this into an AMDGPU and AMDKFD part. The bigger patches that
add lots of new code are not cherry-picked and squashed. Instead I
copied, reorganized and cleaned up the code by hand and then split it
into some semblance of a sensible history. I acknowledged major
contributors with signed-off-by lines but didn't list everyone who
ever touched that code (would probably be most of the team).
I pushed an updated Thunk (rebased on ROCm 1.7) that works with this
KFD update. Most testing was done on Fiji with KFDTest (Yong started
working on open-sourcing it). I was also able to run the OpenCL
version of SHOC, though most sub-tests still fail.
KFDTest can manage VRAM and system memory, submit shader dispatches,
receive events. I haven't tested multi-GPU yet, but in theory that
should also work, with system memory buffers shared between multiple
GPUs.
The big missing piece at this point is support for userptr memory
(user-allocated memory mapped for GPU access). That's giong to be my
next patch series that should enable a much wider range of real-world
applications.
AMDGPU:
Patches 1-5 are minor cleanups and fixes
Patches #1-#5 are Reviewed-by: Christian König <christian.koe...@amd.com>.
Patches 6-10 add and implement KFD->KGD interfaces for GPUVM
AMDKFD:
Patches 11-13 are minor cleanups and fixes
Patches 14-25 add all the GPUVM memory management functionality
