drm/amdgpu: Remove unnecessary domain argument

2022-12-14T21:48:00+00:00

Remove the "domain" argument to amdgpu_bo_create_kernel_at() since this
function takes an "offset" argument which is the offset off of VRAM, and as
such allocation always takes place in VRAM. Thus, the "domain" argument is
unnecessary.

drm/amdgpu: Add notifier lock for KFD userptrs

2022-12-14T14:48:05+00:00

Add a per-process MMU notifier lock for processing notifiers from
userptrs. Use that lock to properly synchronize page table updates with
MMU notifiers.

drm/amdgpu: add drv_vram_usage_va for virt data exchange

2022-11-29T16:03:35+00:00

For vram_usagebyfirmware_v2_2, fw_vram_reserve is not used. So
fw_vram_usage_va is NULL, and cannot do virt data exchange
anymore. Should add drv_vram_usage_va to do virt data exchange
in vram_usagebyfirmware_v2_2 case. And refine some code style
checks in pre add vram reservation logic patch

radeon:
- ACPI ref count fix
- HDA audio notifier support
- Move Kconfig into radeon directory

UAPI:
- Add new GEM_CREATE flags to help to transition more KFD functionality to the DRM UAPI.
  These are used internally in the driver to align location based memory coherency
  requirements from memory allocated in the KFD with how we manage GPUVM PTEs.  They
  are currently blocked in the GEM_CREATE IOCTL as we don't have a user right now.
  They are just used internally in the kernel driver for now for existing KFD memory
  allocations. So a change to the UAPI header, but no functional change in the UAPI.

drm/amdgpu: fix userptr HMM range handling v2

2022-11-17T05:23:30+00:00

The basic problem here is that it's not allowed to page fault while
holding the reservation lock.

So it can happen that multiple processes try to validate an userptr
at the same time.

Work around that by putting the HMM range object into the mutex
protected bo list for now.

v2: make sure range is set to NULL in case of an error

amdgpu_ttm_tt_set_userptr() is also called by the KFD as part of

the GPUVM for a KFD process so update the function description.
