ff758a12b4 drm/amdgpu: Add amdgpu <--> amdkfd gfx8 interface
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.

32c22e994f drm/amdgpu: add amdgpu <--> amdkfd gfx7 interface
This patch adds the gfx7 interface file between amdgpu and amdkfd. This
interface file mirrors (some) of the functions in radeon_kfd.c
(the interface file between radeon and amdkfd).

The gfx7 interface is used when it is run on a Kaveri-based system.

This interface file was used for bring-up of amdkfd on amdgpu and for
debugging purposes. For users who would like to run HSA on Kaveri, please
use the radeon graphic driver.

Note: CONFIG_DRM_AMDGPU_CIK must be selected for amdgpu to handle Kaveri.

v2: removed MTYPE_NONCACHED enum definition as it is defined in another
patch

130e0371b7 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.
