8edb94562a drm/amd/display: WA to ensure MUX chip gets SUPPORTED_LINK_RATES of eDP
[Why]
Customer make a request to add this WA by driver.

Some MUX chips will power down with eDP 1.4 panel and
lose previous supported link rates(DPCD 0x010) in
customer's hybrid-GPU designs. As a result, during sleep
resuming and screen turns on from idle, link training
will be performed incorrectly and eDP will flicker or
black screen. These MUX chips need source to read DPCD
0x010 again during LKT so that it can restore supported
link rates of panel.

For driver side, supported link rate set is fetched when
link detection, no need to update but just read again
as WA.

[How]
Read DPCD 0x010 again during link training for eDP 1.4.

36f878501e drm/amd/display: Blank HUBP during pixel data blank for DCN30
[Why]
There are some timings for which we support p-state
switching in active, but not in blank. There was a
previous issue where a timing that had active-only
support would hang a p-state request when we were in
an extended blanking period. The workaround for that
issue was to block active-only p-state switching,
but that resulted in a lack of p-state support for
some common timings such as 1440p60. We want to fix
that issue properly by un-blocking p-state requests
while the display is blanked, so that we can re-enable
active-only p-state switching.

[How]
 - new version of blank_pixel_data for DCN30
 - call hubp->set_blank from dcn30_blank_pixel_data
 - blank every hubp in the mpcc tree, and odm tree
 - on blank enable, wait until the next frame before blanking HUBP

6f2239ccdf drm/amd/display: Keep GSL for full updates with planes that flip VSYNC
[Why]
When enabling PIP in Heaven, the PIP planes are VSYNC
flip and is also the top-most pipe. In this case GSL
will be disabled because we only check immediate flip
for the top pipe. However, the desktop planes are still
flip immediate so we should at least keep GSL on until
the full update.

[How]
Check each pipe in the tree to see if any planes
are flip immediate. Maintain the GSL lock if yes,
and take it down after when unlocking if any planes
are flipping VSYNC. Keeping GSL on with VSYNC +
flip immediate planes causes corruption.

c5ff0c1950 drm/amd/display: Clean up debug macros
This patch simplifies the ASSERT*() and BREAK_TO_DEBUGGER() macros:
- Move the dependency check of CONFIG_KGDB into Kconfig
- Unify the kgdb_breakpoint() call
- Drop the non-existing CONFIG_HAVE_KGDB

Also align the behavior of ASSERT() macro in both cases with and
without CONFIG_DEBUG_KERNEL_DC.

0ca3418272 drm/amd/display: Don't invoke kgdb_breakpoint() unconditionally
ASSERT_CRITICAL() invokes kgdb_breakpoint() whenever either
CONFIG_KGDB or CONFIG_HAVE_KGDB is set.  This, however, may lead to a
kernel panic when no kdb stuff is attached, since the
kgdb_breakpoint() call issues INT3.  It's nothing but a surprise for
normal end-users.

For avoiding the pitfall, make the kgdb_breakpoint() call only when
CONFIG_DEBUG_KERNEL_DC is set.

594b6f7370 drm/amd/display: Fix kernel panic by dal_gpio_open() error
Currently both error code paths handled in dal_gpio_open_ex() issues
ASSERT_CRITICAL(), and this leads to a kernel panic unnecessarily if
CONFIG_KGDB is enabled.  Since basically both are non-critical errors
and can be recovered, drop those assert calls and use a safer one,
BREAK_TO_DEBUGGER(), for allowing the debugging, instead.

this sort of information helps debug. This commit introduces tracepoints

8b198f6e94 drm/amd/display: Add pipe_state tracepoint
This commit introduces a trace mechanism for struct pipe_ctx by adding a
middle layer struct in the amdgpu_dm_trace.h for capturing the most
important data from struct pipe_ctx and showing its data via tracepoint.
This tracepoint was added to dc.c and dcn10_hw_sequencer, however, it
can be added to other DCN architecture.

9d83722d06 drm/amd/display: Decouple amdgpu_dm_trace from service
Our DC currently uses some of the tracepoint function inside a DC
header, which means that many other files implicitly include part of the
trace function. This situation limits how we can expand this feature for
other parts of the driver by generating multiple compilation errors when
we try to reuse some of the existing structures. This commit decouples
part of the amdgpu_dm_trace from DC core to simplify the trace
enlargement in future changes.
