9976782f33 drm/omap: dss: Remove DSS encoders get_timings operation
The get_timings operation from DSS encoders (not to be confused with the
identically named operation in omap_dss_driver) is never called. Remove
it.

The operations are never used, remove them. If the need to set wide

36c61ae2b7 drm/omap: dss: Remove display ordering from dss/display.c
As ordering of the dss_devices based on DT aliases is now implemented in
omap_drm.c, there is no need to do the ordering in dss/display.c
anymore.

At the same time remove the alias member of the omap_dss_device struct
since it is no longer needed. The only place it was used is in the
omapdss_register_display() function.

6b048706f4 drm/i915: Forcibly flush unwanted requests in drop-caches
Add a mode to debugfs/drop-caches to flush unwanted requests off the GPU
(by wedging the device and resetting). This is very useful if a test
terminated leaving a long queue of hanging batches that would ordinarily
require a round trip through hangcheck for each.

It reduces the inter-test operation to just a write into drop-caches to
reset driver/GPU state between tests.

e0ff7a7cdd drm/i915: Early rejection of buffer allocations larger than RAM
We currently try to pin and allocate the whole buffer at a time. If that
object is larger than RAM, we will try to pin the whole of physical
memory, force the machine into oom, and then still fail the allocation.

If the request is obviously too large, error out early. We opt to do
this in the backend to make it easy to use alternate paths that do not
require the entire object pinned, or may easily handle proxy objects
that are larger than physical memory.

If we fail to write the user relocation back when it is changed, force
ourselves to take the slow relocation path where we can handle faults in
the write path. There is still an element of dubiousness as having
patched up the batch to use the correct offset, it no longer matches the
presumed_offset in the relocation, so a second pass may miss any changes

48e905048f drm/i915: Explicitly mark Global GTT address spaces
So far we have been relying on vm->file pointer being NULL to declare

This has the unfortunate consequence that the default kernel context is
also declared GGTT and interferes with the following patch which wants to

Change the is_ggtt test to use an explicit flag in struct address_space to
solve this issue.

struct.

a64f888749 drm/i915/intel_csr.c Fix DMC FW Loading issue on ICL.
This patch resolves the DMC FW loading issue.
Earlier DMC FW package have only one DMC FW for one stepping. But as such
there is no such restriction from Package side.
For ICL icl_dmc_ver1_07.bin binary package has DMC FW for 2 steppings.
So while reading the dmc_offset from package header, for 1st stepping
offset used to come 0x0 and was working fine till now.
But for second stepping and other steppings, offset is non zero number
and is in dwords. So we need to convert into bytes to fetch correct DMC
FW from correct place.

v2 : Added check for DMC FW max size for various gen. (Imre Deak)
v3 : Corrected naming convention for various gen. (Imre Deak)
v4 : Initialized max_fw_size to 0
v5 : Corrected DMC FW MAX_SIZE for various gen. (Imre Deak)

5ce70c799a drm_dp_cec: check that aux has a transfer function
If aux->transfer == NULL, then just return without doing
anything. In that case the function is likely called for
a non-(e)DP connector.

This never happened for the i915 driver, but the nouveau and amdgpu
drivers need this check.

The alternative would be to add this check in those drivers before
every drm_dp_cec call, but it makes sense to check it in the
drm_dp_cec functions to prevent a kernel oops.

4a47765103 drm/i915: Keep physical cursors pinned while in use
The optimisation inherent in commit 6a2c4232ec ("drm/i915: Make the
physical object coherent with GTT") relies on that once we allocated a
cursor we would have coherent, zero overhead access to the scanout plane
holding the cursor. That is we could then do the very frequent cursor
updates X enjoys with no indirection or kernel involvement. However,
that all hinges on the GGTT mmap of the cursor being pinned and not
require refaulting on each access -- handling such a page fault likely
requires the busy GGTT to be rearranged causing a stall. A very simple
fix is then to handle the physical cursor exactly like other cursors and
keep its vma pinned while active.

70b73f9ac1 drm/i915/ringbuffer: Delay after invalidating gen6+ xcs
During stress testing of full-ppgtt (on Baytrail at least), we found
that the invalidation around a context/mm switch was insufficient (writes
would go astray). Adding a second MI_FLUSH_DW barrier prevents this, but
it is unclear as to whether this is merely a delaying tactic or if it is
truly serialising with the TLB invalidation. Either way, it is
empirically required.

v2: Avoid the loop for readability;

09c4b49457 drm/virtio: fix bounds check in virtio_gpu_cmd_get_capset()
This doesn't affect runtime because in the current code "idx" is always
valid.

First, we read from "vgdev->capsets[idx].max_size" before checking
whether "idx" is within bounds.  And secondly the bounds check is off by
one so we could end up reading one element beyond the end of the
vgdev->capsets[] array.

0e7a3d4b66 drm/virtio: Replace ttm_bo_unref with ttm_bo_put
The function ttm_bo_put releases a reference to a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.

A call to ttm_bo_unref takes the address of the TTM BO object's pointer and
clears the pointer's value to NULL. This is not necessary in most cases and
sometimes even worked around by the calling code. A call to ttm_bo_put only
releases the reference without clearing the pointer.

The current behaviour of cleaning the pointer is kept in the calling code,
but should be removed if not required in a later patch.
