[Why]
For the HW cursor, its current position in the pipe_ctx->stream struct is
not affected by the 180 rotation, i. e. the top left corner is still at
0,0. However, the DPP & HUBP set_cursor_position functions require rotated
position.
The current approach is hard-coded for ODM 2:1, thus it's failing for
ODM 4:1, resulting in a double cursor.
[How]
Instead of calculating the new cursor position relatively to the
viewports, we calculate it using a viewavable clip_rect of each plane.
The clip_rects are first offset and scaled to the same space as the
src_rect, i. e. Stream space -> Plane space.
In case of a pipe split, which divides the plane into 2 or more viewports,
the clip_rect is the union of all the viewports of the given plane.
With the assumption that the viewports in HUBP's set_cursor_position are
in the Plane space as well, it should produce a correct cursor position
for any number of pipe splits.

When KFD asks CP to preempt queues, other than preempt CP queues, CP
also requests SDMA to preempt SDMA queues with UNMAP_LATENCY timeout.
Currently queue_preemption_timeout_ms is 9000 ms by default but can be
configured via module parameter. KFD_UNMAP_LATENCY_MS is hard coded as
4000 ms though. This patch ties KFD_UNMAP_LATENCY_MS to
queue_preemption_timeout_ms so in a slow system such as emulator, both
CP and SDMA slowness are taken into account.

On DCE 6, DP audio was not working. However, it worked when an
HDMI monitor was also plugged in.
Looking at dce_aud_wall_dto_setup it seems that the main
difference is that we use DTO1 when only DP is plugged in.
When programming DTO1, it uses audio_dto_source_clock_in_khz
which is set from get_dp_ref_freq_khz
The dce60_get_dp_ref_freq_khz implementation looks incorrect,
because DENTIST_DISPCLK_CNTL seems to be always zero on DCE 6,
so it isn't usable.
I compared dce60_get_dp_ref_freq_khz to the legacy display code,
specifically dce_v6_0_audio_set_dto, and it turns out that in
case of DCE 6, it needs to use the display clock. With that,
DP audio started working on Pitcairn, Oland and Cape Verde.
However, it still didn't work on Tahiti. Despite having the
same DCE version, Tahiti seems to have a different audio device.
After some trial and error I realized that it works with the
default display clock as reported by the VBIOS, not the current
display clock.
The patch was tested on all four SI GPUs:
* Pitcairn (DCE 6.0)
* Oland (DCE 6.4)
* Cape Verde (DCE 6.0)
* Tahiti (DCE 6.0 but different)
The testing was done on Samsung Odyssey G7 LS28BG700EPXEN on
each of the above GPUs, at the following settings:
* 4K 60 Hz
* 1080p 60 Hz
* 1080p 144 Hz

For later VBIOS versions, the fractional feedback divider is
calculated as the remainder of dividing the feedback divider by
a factor, which is set to 1000000. For reference, see:
- calculate_fb_and_fractional_fb_divider
- calc_pll_max_vco_construct
However, in case of old VBIOS versions that have
set_pixel_clock_v3, they only have 1 byte available for the
fractional feedback divider, and it's expected to be set to the
remainder from dividing the feedback divider by 10.
For reference see the legacy display code:
- amdgpu_pll_compute
- amdgpu_atombios_crtc_program_pll
This commit fixes set_pixel_clock_v3 by dividing the fractional
feedback divider passed to the function by 100000.

Adjust the nominal (and performance) clocks for DCE 8-10,
and set them to 625 MHz, which is the value used by the legacy
display code in amdgpu_atombios_get_clock_info.
This was tested with Hawaii, Tonga and Fiji.
These GPUs can output 4K 60Hz (10-bit depth) at 625 MHz.
The extra 15% clock was added as a workaround for a Polaris issue
which uses DCE 11, and should not have been used on DCE 8-10 which
are already hardcoded to the highest possible display clock.
Unfortunately, the extra 15% was mistakenly copied and kept
even on code paths which don't affect Polaris.
This commit fixes that and also adds a check to make sure
not to exceed the maximum DCE 8-10 display clock.
