4ce4728b51 drm/radeon: add new callback for info ioctl register accessor
This adds a callback for each asic family to determine what
registers are allowed to be read back via the info ioctl.

The idea here is to allow usermode to query things like GPU status
registers or GPU harvest registers for profiling and determining
the gfx config.

67ba31d352 drm/radeon: add an output_csc property
This adds the drm property for output csc (e.g.,
transform of output display colorspace).  Currently
only common ones (TV RGB, BT.601, BT.709) are supported,
but bypass and tv rgb are really the only useful ones at
the moment.  Additionally we could expose a user adjustable
matrix in the future.

This commit just adds the property.  The hw support will
be added in subsequent patches.

a239118a24 drm/radeon: drop ttm two ended allocation
radeon_bo_create() calls radeon_ttm_placement_from_domain()
before ttm_bo_init() is called.  radeon_ttm_placement_from_domain()
uses the ttm bo size to determine when to select top down
allocation but since the ttm bo is not initialized yet the
check is always false.  It only took effect when buffers
were validated later.  It also seemed to regress suspend
and resume on some systems possibly due to it not
taking effect in radeon_bo_create().

radeon_bo_create() and radeon_ttm_placement_from_domain()
need to be reworked substantially for this to be optimally
effective.  Re-enable it at that point.

b661010171 drm/radeon: fix wait to actually occur after the signaling callback
A normal wait adds to the front of the tail. By doing something
similar to fence_default_wait the fence code can run without racing.

This is a complete fix for "panic on suspend from KDE with radeon",
and a partial fix for "Radeon: System pauses on TAHITI". On tahiti
si_irq_set needs to be fixed too, to completely flush the writes
before radeon_fence_activity is called in radeon_fence_enable_signaling.

5636d2f842 drm/radeon: Restore GART table contents after pinning it in VRAM v3
The GART table BO has to be moved out of VRAM for suspend/resume. Any
updates to the GART table during that time were silently dropped without
this change. This caused GPU lockups on resume in some cases, see the bug
reports referenced below.

This might also make GPU reset more robust in some cases, as we no longer
rely on the GART table in VRAM being preserved across the GPU
lockup/reset.

v2: Add logic to radeon_gart_table_vram_pin directly instead of
    reinstating radeon_gart_restore
v3: Move code after assignment of rdev->gart.table_addr so that the GART
    TLB flush can work as intended, add code comment explaining why we're
    doing this

5a8888a311 drm/radeon: Don't increment pipe_id in kgd_init_pipeline
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.

ceae881bfa drm/radeon: Impl. new gtt allocate/free functions
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.

  because the kernel was not officialy released yet, and this the first

"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)));

It causes memory corruption to copy a negative size buffer.

38c2adfb00 drm/radeon: Init amdkfd only if it was compiled
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.

fec77bb50f drm/radeon: Assign VMID to PASID for IH in non-HWS mode
This patch fixes a bug in kgd_set_pasid_vmid_mapping(), where the function
only updated the ATC registers (IOMMU) with the new VMID <--> PASID mapping,
but didn't update the IH (Interrupt) registers.

The bug only occurs when using non-HWS mode. In HWS mode, the CP automatically
does the VMID <--> PASID mapping.

If timeout happens, kgd_hqd_destroy() just returns -ETIME leaving queue

It may cause a deadlock, so the patch proposes to release queue before return.

While developing MST support I noticed I often got the wrong data

Based on a patch by Alex, but I've made it a bit more obvious when

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.

   - Rockchip drm driver merged.

   - imx gpu driver moved out of staging

  Other stuff:

   - core:
        panel - MIPI DSI + new panels.
        expose suggested x/y properties for virtual GPUs

   - i915:

It has helped me to add a NULL pointer check that was suggested at
http://lists.freedesktop.org/archives/dri-devel/2014-October/070663.html

I am not familiar with the code. But the change looks sane
and we need something fast at this stage of 3.18 development.

91ed6fd2c3 gpu/radeon: Set flag to indicate broken 64-bit MSI
Some radeon ASICs don't support all 64 address bits of MSIs despite
advertising support for 64-bit MSIs in their configuration space.

This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can
be assigned with some of the high address bits set.

This makes use of the newly introduced "no_64bit_msi" flag in structure
pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs
on those adapters.

355a701838 drm/gem: Warn on illegal use of the dumb buffer interface v2
It happens on occasion that developers of generic user-space applications
abuse the dumb buffer API to get hold of drm buffers that they can both
mmap() and use for GPU acceleration, using the assumptions that dumb buffers
and buffers available for GPU are
a) The same type and can be aribtrarily type-casted.
b) fully coherent.

This patch makes the most widely used drivers warn nicely when that happens,
the next step will be to fail.

v2: Move drmP.h changes to drm_gem.h. Fix Radeon dumb mmap breakage.
