The root of the problem is that the default segment size for sgt is
(UINT_MAX & PAGE_MASK), and the default segment size for device dma is
64K. As such, if you compare the 2, you would deduce that the sg segment
will overflow the device's capacity. In reality, the hardware can
accommodate the larger sg segments, it's just not initializing its max
segment properly. This patch initializes the max segment size for the
mdss device, which gets rid of that pesky warning.

José Roberto de Souza 7b19914383 drm/mst: Don't do atomic checks over disabled managers
When a main MST port is disconnected drivers should call
drm_dp_mst_topology_mgr_set_mst() disabling the MST manager, this
function will set manager mst_primary to NULL and it will cause the
crash bellow on the next atomic check when trying to access
mst_primary->port.

As there is no use in running checks over managers that are not
active this patch will skip it.

Alvin Lee 30c9b7a133 drm/amd/display: Don't always set pstate true if dummy latency = 0
[Why]
If dummy pstate latency is 0 we should report the actual
pstate support, and not that pstate is always supported.

[How]
Don't always program pstate support true

Noah Abradjian e8027e0884 drm/amd/display: Add double buffering to dcn20 OCSC
[Why]
When rapidly adjusting colour properties (e.g. brightness), screen tearing was observed.
This was due to overwritten values in OCSC registers. In dcn10, this issue had been fixed by
implementing double buffering by alternating OCSC modes.

[How]
Alternate which OCSC registers are used by switching modes each time.
This double buffers the CSC writes.

Nicholas Kazlauskas 1295524e6f drm/amd/display: Soft reset DMUIF during DMUB reset
[Why]
We need to ensure that the DMUIF in MMHUBBUB is also in reset so we
aren't generating requests while the DMCUB is in reset.

[How]
Set DMUIF_SOFT_RESET=1 on reset and DMUIF_SOFT_RESET=0 on reset
release.

Nicholas Kazlauskas 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.

Nicholas Kazlauskas 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.

Nikola Cornij 6d822156d0 drm/amd/display: Disable secondary link for certain monitors
[why]
If the specific monitor supports DSC, the secondary link should be
disabled, and the other way around, too: if either that monitor or
our ASIC doesn't support DSC, the secodary link should be enabled.

[how]
Add a monitor patch and disable secondary link if that monitor
is detected and if ASIC supports DSC, or otherwise enable secondary
link.
