drm/amdkfd: Fixed kfd_process cleanup on module exit.

2023-03-15T22:21:05+00:00

Handle case when module is unloaded (kfd_exit) before a process space (mm_struct) is released. v2: Fixed potential race conditions by removing all kfd_process from the process table first, then working on releasing the resources. v3: Fixed loop element access / synchronization. Fixed extra empty lines. Signed-off-by: David Belanger Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Fix handling of KFD initialization failures

2020-09-22T16:24:11+00:00

Remember KFD module initializaton status in a global variable. Skip KFD device probing when the module was not initialized. Other amdgpu_amdkfd calls are then protected by the adev->kfd.dev check. Also print a clear error message when KFD disables itself. Amdgpu continues its initialization even when KFD failed.

drm/amdkfd: add missing void argument to function kgd2kfd_init

Function kgd2kfd_init is missing a void argument, add it to clean up the non-ANSI function declaration. Acked-by: Randy Dunlap Signed-off-by: Colin Ian King Signed-off-by: Alex Deucher

drm/amdkfd: Add procfs-style information for KFD processes

2019-06-20T16:34:00+00:00

Add a folder structure to /sys/class/kfd/kfd/ called proc which contains subfolders, each representing an active KFD process' PID, containing 1 file: pasid. Signed-off-by: Kent Russell Reviewed-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Remove kgd2kfd function pointers

drm/amdgpu: Relocate kgd2kfd function declaration

2019-01-14T20:04:28+00:00

Since amdkfd is merged into amdgpu module and amdgpu can access amdkfd directly, move declaration of kgd2kfd functions from kfd_priv.h to amdgpu_amdkfd.h Signed-off-by: Amber Lin Reviewed-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Move KFD parameters to amdgpu (v3)

2018-08-28T16:51:11+00:00

After merging KFD into amdgpu, move module parameters defined in KFD to amdgpu_drv.c, where other module parameters are declared. v2: add kernel-doc comments v3: rebase and fix parameter variable name (Alex) Signed-off-by: Amber Lin Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Merge amdkfd into amdgpu

2018-08-28T16:22:42+00:00

Since KFD is only supported by single GPU driver, it makes sense to merge amdgpu and amdkfd into one module. This patch is the initial step: merge Kconfig and Makefile. v2: also remove kfd from drm Kconfig Signed-off-by: Amber Lin Acked-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher
