To avoid underflow seen on Polaris10 with some 3440x1440
144Hz displays. As the threshold of 190 us cuts too close
to minVBlankTime of 192 us.

<content type='text'>
commit 920bb38c518408fa2600eaefa0af9e82cf48f166 upstream.

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.

<title>drm/amd/display: Don't invoke kgdb_breakpoint() unconditionally</title>

<content type='text'>
commit 8b7dc1fe1a5c1093551f6cd7dfbb941bd9081c2e upstream.

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.

commit 55bb919be4e4973cd037a04f527ecc6686800437 upstream.

Ideally this should be a multiple of the VM block size.
2MB should at least fit for Vega/Navi.

On connector destruction call drm_dp_mst_topology_mgr_destroy
to release resources allocated in drm_dp_mst_topology_mgr_init.
Do it only if MST manager was initilized before otherwsie a crash
is seen on driver unload/device unplug.

commit 37b7cb10f07c1174522faafc1d51c6591b1501d4 upstream.

[WHY]
When disabling DP video, the current REG_WAIT timeout
of 50ms is too low for certain cases with very high
VSYNC intervals.

[HOW]
Increase the timeout to 102ms, so that
refresh rates as low as 10Hz can be handled properly.
