This patch fixes the behavior of kgd_init_pipeline in that this function
shouldn't automatically increase the pipe_id argument by 1 right at the start
of the function.
This is because the first_pipe value might not be always 1, and because a
proper interface function should not hide this info inside its implementation.
In other words, the calling function should provide the real pipe_id and not
count on kgd_init_pipeline to "fix" it.

[danvet: Squash in simplification patch from kbuild.]
Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
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.

- Complete overhaul to the main IOCTL function, kfd_ioctl(), according to
drm_ioctl() example. This includes changing the IOCTL definitions, so it
breaks compatibility with previous versions of the userspace. However,
because the kernel was not officialy released yet, and this the first
kernel that includes amdkfd, I assume I can still do that at this stage.
- A couple of bug fixes for the non-HWS path (used for bring-ups and
debugging purposes only).

The test:

"size" is an integer and it's controled by the user so it can be

dwords = size / 4;

RADEON_COPY_MT(buffer, data, (int)(dwords * sizeof(u32)));

This patch changes the radeon_kfd_init(), which is used to initialize the
interface between radeon and amdkfd, so the interface will be initialized only
if amdkfd was build, either as module or inside the kernel image.
In the modules case, the symbol_request() will be used (same as old code). In
the in-image compilation case, a direct call to kgd2kfd_init() will be done.
For other cases, radeon_kfd_init() will just return false.
This patch is necessary because in case of the following specific
configuration: kernel 32-bit, no modules support, random kernel base and no
hibernation, the symbol_request() doesn't work as expected - it doesn't return
NULL if the symbol doesn't exists - which makes the kernel panic.

Pull drm updates from Dave Airlie:
"Highlights:
- AMD KFD driver merge
This is the AMD HSA interface for exposing a lowlevel interface for
GPGPU use. They have an open source userspace built on top of this
interface, and the code looks as good as it was going to get out of
tree.
- Initial atomic modesetting work
The need for an atomic modesetting interface to allow userspace to
try and send a complete set of modesetting state to the driver has
arisen, and been suffering from neglect this past year. No more,
the start of the common code and changes for msm driver to use it
are in this tree. Ongoing work to get the userspace ioctl finished
and the code clean will probably wait until next kernel.
- DisplayID 1.3 and tiled monitor exposed to userspace.
Tiled monitor property is now exposed for userspace to make use of.
