Because amdkfd will need to work both with radeon and amdgpu, don't include
header files that are in radeon's folder.
Instead, use the common amd include folder and move amdkfd specific defines to
amdkfd header files.

This patch creates a new file, cik_structs.h, and puts the cik_mqd and
cik_sdma_rlc_registers structures in that file.
The new file is placed in a common include folder under the drm/amd folder, so
it will be shared among all amd drm drivers.

This patch moves to radeon the initialization of compute vmid.
That initializations was done in kfd-->kgd interface, but doing it in radeon
as part of radeon's H/W initialization routines is more appropriate.
In addition, this simplifies the kfd-->kgd interface.
The patch removes the function from the interface file and from the interface
declaration file.
The function initializes memory apertures to fixed base/limit address and non
cached memory types.

This patch makes the gart's buffer size calculation more accurate. This buffer
is needed per GPU.
It takes into account maximum number of MQDs, runlist packets, kernel queues
and reserves 512KB for other misc allocations.
The total size is just shy of 4MB, for 32 processes and 128 queues per
process, which are the defaults for amdkfd kernel module parameters.

This patch adds new kfd gtt sub-allocator functions that service the amdkfd
driver when it wants to use gtt memory.
The sub-allocator uses a bitmap to handle the memory area that was transferred
to it during init. It divides the memory area into chunks, according to chunk
size parameter.
The allocation function will allocate contiguous chunks from that memory area,
according to the requested size. If the requested size is smaller than the
chunk size, a single chunk will be allocated.

This patch adds the implementation of the gtt interface functions.
The allocate function will allocate a single bo, pin and map it to kernel
memory. It will return the gpu address and cpu ptr as arguments.
v2:
The bulk of the allocations in the GART is for MQDs. MQDs represent active
user-mode queues, which are on the current runlist. It is important to
remember that active queues doesn't necessarily mean scheduled/running
queues, especially if there is over-subscription of queues or more than a
single HSA process.
Because the scheduling of the user-mode queues is done by the CP firmware,
amdkfd doesn't have any indication if the queue is scheduled or not. If the
CP will try to schedule a queue, and its MQD is not present, this will
probably stuck the CP permanently, as it will load garbage from the GART
(the address of the MQD is given to the CP inside the runlist packet).
In addition, there are a couple of small allocations which also should
always be pinned - runlist packets (2 packets) and HPDs. runlist packets can
be quite large, depending on number of processes and queues.
This new allocate function represents the short/mid-term solution of limiting
the total memory consumption to around 4MB by default.
The long-term solution is to create a mechanism through which radeon/ttm can
ask amdkfd to clear GART/VRAM memory due to memory pressure.
Then, amdkfd will preempt the running queues and wait until the memory pressure
is over. After that, amdkfd will reschedule the queues.

This patch adds two new functions to the kfd-->kgd interface:
init_gtt_mem_allocation, which allocate a large enough buffer on the amdkfd
needs, such as mqds, hpds, kernel queue, fence and runlists. This function
is only called once per GPU device. The size of the allocated buffer is
based on the maximum number of HSA processes and maximum number of queues
per HSA process (two amdkfd kernel module parameters).
free_gtt_mem, which frees a buffer that was allocated on the gart aperture.

git://anongit.freedesktop.org/drm-intel into drm-next
Next batch of atomic work. Most important is the propertification from Rob
and the nth iteration of the actual atomic ioctl originally from Ville.
Big differences compared to earlier revisions:
- Core properties are now fully handled by the core, drivers can only
handle driver-specific properties.
- Atomic props&ioctl are opt-in per file_priv, userspace needs to
explicitly ask for it (like universal plane support).
- For now all hidden behind the atomic module option until this has
settled a bit.
- Atomic modesets are currently not possible since the exact abi for how
to handle the mode property is still under discussion.
Besides this some cleanup patches from me and the addition of per-object
state to global state backpointers to simplify drivers.

We do not need to track the state of the IPU DI's clock flags by having
each display bridge calling back into imx-drm-core, and then back out
into ipuv3-crtc.c.
ipuv3-crtc can instead just scan the list of encoders to retrieve their
type, and build up a picture of which types of encoders are attached.
We can then use this information to configure the IPU DI clocking mode
without any uncertainty - if we have multiple bridges connected to the
same DI, if one of them requires a synchronous DI clock, that's what we
must use.
