When enabling animation/static splash in LK, drm/kms driver needs
to involve handoff code to support smooth transition. In display
driver's probe, it will do following items:
1. Check the status in LK for early splash.
2. Add data bus bandwidth voting in function sde_splash_init.
2. Handle SMMU mapping issue to avoid SMMU fault problem.
3. Bypass hardware reset to avoid glitch.
And after user's space is up, when first commit's vblank comes,
it will call functions to:
1. Tell LK to stop static/animation display and to exit.
2. Set early_domain_map_attr to 1 to enable stage 1 translation in
iommu driver.
3. Check the property of commit.If it's for HDMI, release HDMI
resource. If for DSI, release DSI resource.
4. Recycle the memory to be available to system.
5. Withdraw the bus bandwidth voting.

Update vblank reference counts via the exposed sde_crtc_vblank
function, rather than attempting to zero it on the side during
CRTC disable operations. This allows the power voting to be
updated correctly based on the vblank reference count value.

This patch provides a module parameter to control whether each
plane outputs the previously configured content or a black frame
during the resume operation. The default is set to output a
black frame.

Move the power resource request/release from the sde kms layer
into the CRTCs so that proper accounting for suspend/resume
operations may be done. A single power resource request is
made as long while the CRTC's vblank request ref count is not
zero and the driver is not in a suspended state.

Explicitly disable connector DPMS and CRTC active states on
system suspend, and restore the previous state during a
system resume. This allows the underlying drivers to trigger
a DPMS callback for handling any panel related power disables
while still preserving the DRM atomic state.

We should have a corresponding syncpoint_fence trace
for every syncpoint_fence_expire trace. In case the
fence is already signaled then make sure to have
syncpoint_fence trace before syncpoint_fence_expire
trace.
Also take an extra refcount for fence which will make
sure that the fence pointer is valid in the trace even
if the fence is signaled.

adreno_show() to safely dump all the registers without a system hang.

The generic msm_gpu_pm_resume/msm_gpu_pm_suspend functions have
built-in reference counting but the a5xx specific functions
are doing unconditional a5xx specific setup / teardown that
would behave very badly if they were not accompanied by an
actual power up / power down.

For calculation of busy time and total time, KGSL relies on perf
counters and CPU clock. These can be a bit out of sync and may
give GPU busy greater than 100 percent. Updating time at the right
place will give more accurate total time and will avoid crossing
100% in GPU busy calculation.

HDR playback needs metadata to be sent to the sink
while the playback is ongoing and needs a proper
teardown sequence when the playback has ended with respect
to the infoframe being sent to the sink.
This needs a state machine to synchronize start/stop of
the playback with sending the right metadata along with
resetting the infoframe HDMI registers.
Add support for this HDR playback control state machine.

Fix the Y420CMDB EDID block parsing to handle
the case where the block does not include a capability

This case means that all the short video descriptors
support the YUV 420 mode as well.
Also fix the incorrect length check in the parser API.
The capability bitmap has no minimum length field.

[ Upstream commit c5f21c9f878b8dcd54d0b9739c025ca73cb4c091 ]
Return success when the ring is properly initialized, otherwise return
failure.
Tonga SRIOV VF doesn't have UVD and VCE engines, the initialization of
these IPs is bypassed. The system crashes if application submit IB to
their rings which are not ready to use. It could be a common issue if
IP having ring buffer is disabled for some reason on specific ASIC, so
it should check the ring being ready to use.
Bug: amdgpu_test crashes system on Tonga VF.

commit 82fcee526ba8ca2c5d378bdf51b21b7eb058fe3a upstream.
The hash table created during vmw_cmdbuf_res_man_create was
never freed. This causes memory leak in context creation.
Added the corresponding drm_ht_remove in vmw_cmdbuf_res_man_destroy.
Tested for memory leak by running piglit overnight and kernel
memory is not inflated which earlier was.

commit 71f677a91046599ece96ebab21df956ce909c456 upstream.
The ast driver configures a window to enable access into BMC
memory space in order to read some configuration registers.
If this window is disabled, which it can be from the BMC side,
the ast driver can't function.
Closing this window is a necessity for security if a machine's
host side and BMC side are controlled by different parties;
i.e. a cloud provider offering machines "bare metal".
A recent patch went in to try to check if that window is open
but it does so by trying to access the registers in question
and testing if the result is 0xffffffff.
This method will trigger a PCIe error when the window is closed
which on some systems will be fatal (it will trigger an EEH
for example on POWER which will take out the device).
This patch improves this in two ways:
- First, if the firmware has put properties in the device-tree
containing the relevant configuration information, we use these.
- Otherwise, a bit in one of the SCU scratch registers (which
are readable via the VGA register space and writeable by the BMC)
will indicate if the BMC has closed the window. This bit has been
defined by Y.C Chen from Aspeed.
If the window is closed and the configuration isn't available from
the device-tree, some sane defaults are used. Those defaults are
hopefully sufficient for standard video modes used on a server.

Move the input validation for the connector's HDR support
before calling the API to set the infoframe rather than within
the API itself.
This helps to avoid redundant checks and logging.

There is a dead loop in kgsl_devfreq_target(), while governor request
to change GPU frequency. In governor 'userspace' mode, If the requested
frequency (set_freq) is more than the configured frequency and max_freq
is also set to more than the configured frequency, then there is a dead
loop while changing target frequency.
Dead loop occurs due to comparing signed integer with unsigned integer.
So, type casting unsigned integer to signed integer will terminate the
loop when loop variable is less than zero.

The debug option to always ON the GPU clocks does not check the regulator
state. If the user tries to set this option while GPU is in Slumber state
then enabling clocks will fail.
Make sure we enable the GPU regulators before enabling its clocks.
