2015-07-20	drm/amdgpu: Add amdgpu <--> amdkfd gfx8 interface	Ben Goz
	This patch adds the gfx8 interface file between amdgpu and amdkfd. This interface file is currently in use when running on a Carrizo-based system. The interface itself is represented by a pointer to struct kfd_dev. The pointer is located inside amdgpu_device structure. All the register accesses that amdkfd need are done using this interface. This allows us to avoid direct register accesses in amdkfd proper, while also allows us to avoid locking between amdkfd and amdgpu. The single exception is the doorbells that are used in both of the drivers. However, because they are located in separate pci bar pages, the danger of sharing registers between the drivers is minimal. Having said that, we are planning to move the doorbells as well to amdgpu.

2015-07-20	drm/amdgpu: Add H/W agnostic amdgpu <--> amdkfd interface	Oded Gabbay
	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.
