Ben Goz 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.

That initializations was done in kfd-->kgd interface, but doing it in radeon

In addition, this simplifies the kfd-->kgd interface.

declaration file.

The function initializes memory apertures to fixed base/limit address and non

Oded Gabbay e28740ece3 drm/radeon: Add radeon <--> amdkfd interface
This patch adds the interface between the radeon driver and the amdkfd driver.
The interface implementation is contained in radeon_kfd.c and radeon_kfd.h.

The interface itself is represented by a pointer to struct
kfd_dev. The pointer is located inside radeon_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
avoiding locking between amdkfd and radeon.

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 radeon.

v3:

Add interface for sa manager init and fini. The init function will allocate a
buffer on system memory and pin it to the GART address space via the radeon sa
manager.

All mappings of buffers to GART address space are done via the radeon sa
manager. The interface of allocate memory will use the radeon sa manager to sub
allocate from the single buffer that was allocated during the init function.

Change lower_32/upper_32 calls to use linux macros

Add documentation for the interface

v4:

Change ptr field type in kgd_mem from uint32_t* to void* to match to type that
is returned by radeon_sa_bo_cpu_addr

v5:

Change format of mqd structure to work with latest KV firmware
Add support for AQL queues creation to enable working with open-source HSA
runtime.
Move generic kfd-->kgd interface and other generic kgd definitions to a generic
header file that will be used by AMD's radeon and amdgpu drivers
