-Subject: [PATCH 0308/1050] drm/amdgpu: Add H/W agnostic amdgpu <--> amdkfd
- interface
-
-This patch adds an interface file between amdgpu and amdkfd. This
-interface file is H/W agnostic, thus containing functions that
-operate the same for any AMD APU/GPU H/W generation.
-
-The functions in this interface mirror (some) of the functions in
-radeon_kfd.c (the radeon<-->amdkfd interface file). The main functions
-are:
-
-- amdgpu_amdkfd_init - initialize the amdkfd module
-- amdgpu_amdkfd_load_interface - load the H/W interface according to the
- currently probed device
-- amdgpu_amdkfd_device_probe - probe the device in amdkfd
-- amdgpu_amdkfd_device_init - initialize the device in amdkfd
-- amdgpu_amdkfd_interrupt - call the ISR of amdkfd
-- amdgpu_amdkfd_suspend - suspend callback from amdgpu
-- amdgpu_amdkfd_resume - resume callback from amdgpu
-
-This patch also modifies the relevant amdgpu files, to use this new
-interface.
