From 130e0371b7d454bb4a861253c822b9f911ad5d19 Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Fri, 12 Jun 2015 21:35:14 +0300 Subject: 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.
