drm/amdgpu: conditionally compile amdgpu's amdkfd files

2018-05-18T19:18:16+00:00

In case CONFIG_HSA_AMD is not chosen, there is no need to compile amdkfd
files that reside inside amdgpu dirver. In addition, because amdkfd
depends on x86_64 architecture and amdgpu is not, compiling amdkfd files
under i386 architecture can cause compiler errors and warnings.

This patch modifies amdgpu's makefile to build amdkfd files only if
CONFIG_HSA_AMD is chosen. The only file to be compiled unconditionally
is amdgpu_amdkfd.c

There are stub functions that are compiled only if amdkfd is not
compiled. In that case, calls from amdgpu driver proper will go to those
functions instead of the real functions.

v2: instead of using function pointers, use stub functions

v3: initialize kgd2kfd to NULL in case amdkfd is not compiled

drm/amdgpu: Add userptr support for KFD

2018-03-23T19:32:33+00:00

This adds support for allocating, mapping, unmapping and freeing
userptr BOs, and for handling MMU notifiers.

v2: updated a comment

drm/amdgpu: Add MMU notifier type for KFD userptr

2018-03-23T19:32:28+00:00

This commit adds the notion of MMU notifier types GFX and HSA. GFX
continues to work like MMU notifiers did before. HSA adds support for
KFD userptr BOs. The implementation of KFD userptr eviction is a stub
for now.

drm/amdgpu: Add kfd2kgd interface to acquire an existing VM

2018-03-15T21:27:43+00:00

This allows acquiring an existing VM from a render node FD to use it
for a compute process.

Such VMs get destroyed when the original file descriptor is released.
Added a callback from amdgpu_vm_fini to handle KFD VM destruction
correctly in this case.

v2:
* Removed vm->vm_context check in amdgpu_amdkfd_gpuvm_destroy_cb,
  check vm->process_info earlier instead

drm/amdgpu: Move KFD-specific fields into struct amdgpu_vm

2018-03-15T21:27:40+00:00

Remove struct amdkfd_vm and move the fields into struct amdgpu_vm.
This will allow turning a VM created by a DRM render node into a
KFD VM.

v2: Removed vm_context field
