[Why]
The log "DMUB HPD callback" is crucial to identify when DP tunneling
is been established and driver is notified of this event from DMUB.
Same log is shared for long and short hotplug event and we need to
check trailing DC debug log to distinguish between them two, making
debugging on DPIA related issues a bit more troublesome.
[How]
Clearly states in dmesg logs whether this is a long or short hotplug
event.

[Why]
If disable the mmhub vm contexts(set MMVM_CONTEXTS_DISABLE to 0xffff),
driver loading failed on vf due to fence fallback timer expired on all rings.
FLR cannot reset MMVM_CONTEXTS_DISABLE.
So this vf can not be recovered anymore unless trigger a whole gpu reset.
[How]
Under SRIOV, init MMVM_CONTEXTS_DISABLE in gmc11 golden register setting.

we may get underflow when DET is evenly allocated.
[How]
Allocate less DET segments for the lower pixel rate display and
more DET segments for the higher pixel rate display

[Why]
In USB4 DP tunneling, it's possible to have this scenario that
the path becomes unavailable and CM tears down the path a little bit late.
So, in this case, the HPD is high but fails to read any DPCD register.
That causes the link connection type to be set to sst.
And not all sinks are removed behind the MST branch.
[How]
Restore the link connection type if it fails to read DPCD register.

8b/10b encoding needs to add 3% fec overhead into the pbn.
In the Synapcis Cascaded MST hub, the first stage MST branch device
needs the information to determine the timeslot count for the
second stage MST branch device. Missing this overhead will leads to
insufficient timeslot allocation.

[WHY]
Hot plugging and then hot unplugging leads to k1 and k2 values to
change, as signal is detected as a virtual signal on hot unplug. Writing
these values to OTG_PIXEL_RATE_DIV register might cause primary display
to blank (known hw bug).
[HOW]
No longer write k1 and k2 values to register if signal is virtual, we
have safe guards in place in the case that k1 and k2 is unassigned so
that an unknown value is not written to the register either.

[Why & How]
All dc subcomponents should call another dc component via function pointers
stored in a component structure. This is part of dc coding convention since
the beginning. The reason behind this is to improve encapsulation and
polymorphism. The function contract is extracted into a single link service
structure defined in link.h header file and implemented only in link_factory.c instead
of spreading across multiple files in link component file structure.
