830821a64d drm/amd/display: Fallback to DMCUB when command table is missing
[Why]
If the command table isn't available then we can fallback to DMCUB
offloading if it's enabled and available.

[How]
Instead of assigning NULL for supported command table functions we can
fallback to the DMCUB when it's available.

153ca76021 drm/amd/display: Get fb base and fb offset for DMUB from registers
[Why]
Under some hardware initialization sequences the fb base/fb offset
provided can be zero or hardwareinit can happen too late.

We want to ensure that we always have the correct fb_base/fb_offset
when performing DMCUB hardware initialization so we can do DMCUB
command table offloading during first dc hardware init.

[How]
Read from the DCN registers. VBIOS already filled these in for us.

50d2c6027e drm/amd/display: Do not send training pattern if VS Different
[Why]
The DP 1.4a Spec requires that training pattern only under certain
specific conditions. Currently driver will re-send
training pattern every time voltage swing value changes,
but that should not be the case.

[How]
Do not re-send training pattern every time VS values
are different. Only send it on the first iteration.

43563bc2e6 drm/amd/display: update MSA and VSC SDP on video test pattern request
[why]
On video test pattern request we need to update MSA and VSC so
it will match the requested test pattern dynamic range field.

[how]
Update dynamic range field in MSA and disable VSC as updating VSC
info packet is complicated and not required for test pattern purpose.

d9eb70ae61 drm/amd/display: Fix double buffering in dcn2 ICSC
[Why]
When rapidly adjusting video brightness, screen tearing was observed.
This was due to overwritten values in ICSC registers. In dcn10, this issue had been
fixed by implementing double buffering via alternating ICSC modes.
However, the second register set used in dcn1 doesn't exist in dcn2.

[How]
Create new program_input_csc for dcn20.
Use ICSC_B registers instead of COMA registers as second set.

dee5d54283 drm/amd/display: Read inst_fb data back during DMUB loading
[Why]
The inst firmware isn't necessarily fully flushed to framebuffer
memory and the DMCUB can hang due to invalid inst being parsed.

[How]
Like the fix to flush ringbuffer commands before updating the inbox
write pointer we need to read back inst memory before writing the
CW0 registers.

Add a helper to read 64-byte chunks to avoid a large temporary buffer.
Read the remaining leftover bytes if the inst_fb isn't fully aligned.

b7408a0673 drm/amd/display: Flush framebuffer data before passing to DMCUB
[Why]
There's a data race that can occur between when we update the
inbox write pointer vs when the memory for the command actually gets
flushed from the map to the framebuffer.

DMCUB can read stale or partially invalid data when this race occurs.

[How]
Before updating the write pointer we can read back all pending commands
to ensure that we stall for the writes to be flushed to framebuffer.

We don't need to worry about choosing HDP vs VM flush with this
mechanism.

Drop the dmub_srv_cmd_submit() while we're updating this to work
correctly since nothing was actually using this API and the caller
should be explicit about the API flow here - by doing this on execute
we can give some extra time for the flush to finish while
preparing other commands.

We should try to avoid writing single commands
because of this overhead.

35cd89d5a6 drm/amdkfd: use kiq to load the mqd of hiq queue for gfx v9 (v6)
There is an issue that CP will check the HIQ queue to be configured and mapped
with KIQ ring, otherwise, it will be unable to read back the secure buffer while
the gfxoff is enabled even with trusted IP blocks.

v1 -> v2:
- Fix to remove surplus set_resources packets.
- Fill the whole configuration in MQD.
- Change the author as Aaron because he addressed the key point of this issue.
- Add kiq ring lock.

v2 -> v3:
- Free the lock while in error return case.
- Remove the programming only needed by the queue is unmapped.

v3 -> v4:
- Remove doorbell programming because it's used for restarting queue.
- Remove CP scheduler programming because map_queue packet will handle this.

v4 -> v5:
- Remove cp_hqd_active because mec ucode will enable it while use map_queues.
- Revise goto out_unlock.
- Correct the right doorbell offset for HIQ that kfd driver assigned in the
  packet.

v5 -> v6:
- Merge Arcturus fix into this patch because it will get oops in Arcturus
  platform.
