[why]
When DC driver send PSR exit dmub command to DMUB FW, it might not
wait until PSR exit. Then it may hit the following deadlock situation.
1. DC driver send HW LOCK command to DMUB FW due to frame update
2. DMUB FW Set the HW lock
3. DMUB execute PSR exit sequence and stuck at polling DPG Pending
register due to the HW Lock is set
4. DC driver ask DMUB FW to unlock HW lock, but DMUB FW is polling
DPG pending register

[how]
The reason why DC driver doesn't wait until PSR exit is because some of
the PSR state machine state is not update the dc driver. So when DC
driver read back the PSR state, it take the state for PSR inactive.

[why]
The current PSR SU programming margin is fixed base on FHD 60HZ
panel. If the resolution and refresh rate become higher, the time
of current margin might not cover the programming SU time.

[how]
Notice that the programming SU time is the same among different
panels.

Instead of fixing the margin with target line number, change the
margin unit to micro second which indicate the time needed for
programming SU. Then FW set the margin line number base on the
line time and margin time.

Starting from SIENNA CICHLID asic supports two gfx pipes, enabling
two graphics queues, 1 on each pipe, pipe0 queue0 would be the normal
piority queue and pipe1 queue0 would be the high priority queue

Only one queue per pipe is visble to SPI, SPI looks at the priority
value assigned to CP_GFX_HQD_QUEUE_PRIORITY from each of the queue's
HQD/MQD.

Create contexts applying AMDGPU_CTX_PRIORITY_HIGH which submits job
to the high priority queue on GFX pipe1. There would be starvation
of LP workload if HP workload is always available.

v2:
  - remove unnecessary check(Nirmoy)
  - make pipe1 hardware support a separate patch(Nirmoy)
  - remove duplicate code(Shashank)
  - add CSA support for second gfx pipe(Alex)

[Why]
HUBP_UNBOUNDED_REQ_MODE and CURSOR_REQ_MODE are normally set together.
In hubp32_prepare_subvp_buffering() call, CURSOR_REQ_MODE is set based on
whether SubVP is enabled or not.  For non MPO case, both REQ_MODE
registers are set to 1.  But since SubVP is not enabled, then
CURSOR_REQ_MODE is set to 0, overriding the previous value.

[How]
Do not set CURSOR_REQ_MODE to 0 if SubVP is not enabled.  This
will allow CURSOR_REQ_MODE to stay as 1 in the non MPO case.
Add note to follow up and check case for single pipe MPO and
SubVP enabled as this would cause both REQ_MODE registers to be
set to 0 but SubVP enabled would override CURSOR_REQ_MODE to 1.
