Our driver supports overlay planes, and as expected, some userspace
compositor takes advantage of these features. If the userspace is not
enabling the cursor, they can use multiple planes as they please.
Nevertheless, we start to have constraints when userspace tries to
enable hardware cursor with various planes. Basically, we cannot draw
the cursor at the same size and position on two separated pipes since it
uses extra bandwidth and DML only run with one cursor.
For those reasons, when we enable hardware cursor and multiple planes,
our driver should accept variations like the ones described below:
+-------------+ +--------------+
| +---------+ | | |
| |Primary | | | Primary |
| | | | | Overlay |
| +---------+ | | |
|Overlay | | |
+-------------+ +--------------+
In this scenario, we can have the desktop UI in the overlay and some
other framebuffer attached to the primary plane (e.g., video). However,
userspace needs to obey some rules and avoid scenarios like the ones
described below (when enabling hw cursor):
+--------+
|Overlay |
+-------------+ +-----+-------+ +-| |--+
| +--------+ | +--------+ | | +--------+ |
| |Overlay | | |Overlay | | | |
| | | | | | | | |
| +--------+ | +--------+ | | |
| Primary | | Primary | | Primary |
+-------------+ +-------------+ +-------------+
+-------------+ +-------------+
| +--------+ | Primary |
| |Overlay | | |
| | | | |
| +--------+ | +--------+ |
| Primary | | |Overlay | |
+-------------+ +-| |--+
+--------+
If the userspace violates some of the above scenarios, our driver needs
to reject the commit; otherwise, we can have unexpected behavior. Since
we don't have a proper driver validation for the above case, we can see
some problems like a duplicate cursor in applications that use multiple
planes. This commit fixes the cursor issue and others by adding adequate
verification for multiple planes.
Change since V1 (Harry and Sean):
- Remove cursor verification from the equation.

[why]
DP 1.4a spec mandates that if DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is
set, Extended Base Receiver Capability DPCD space must be used. Without
doing that, the three DPCD values that differ will be wrong, leading to
incorrect or limited functionality. MST link rate, for example, could
have a lower value. Also, Synaptics quirk wouldn't work out well when
Extended DPCD was not read, resulting in no DSC for such hubs.
[how]
Modify MST topology manager to use the values from Extended DPCD where
applicable.
To prevent regression on the sources that have a lower maximum link rate
capability than MAX_LINK_RATE from Extended DPCD, have the drivers
supply maximum lane count and rate at initialization time.
This also reverts commit 2dcab875e763 ("Revert drm/dp_mst: Retrieve
extended DPCD caps for topology manager"), brining the change back to the
original commit ad44c03208e4 ("drm/dp_mst: Retrieve extended DPCD caps for

This is something that we've wanted for a while now: the ability to
actually look up the respective drm_device for a given drm_dp_aux struct.
This will also allow us to transition over to using the drm_dbg_*() helpers
for debug message printing, as we'll finally have a drm_device to reference
for doing so.
Note that there is one limitation with this - because some DP AUX adapters
exist as platform devices which are initialized independently of their
respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be
non-NULL until drm_dp_aux_register() has been called. We make sure to point
this out in the documentation for struct drm_dp_aux.
