In order to readout DP SDPs (Secondary Data Packet: DP HDR Metadata Infoframe SDP, DP VSC SDP), it refactors handling DP SDPs codes. It adds new compute routines for DP HDR Metadata Infoframe SDP and DP VSC SDP. And new writing routines of DP SDPs (Secondary Data Packet) that uses computed configs. New reading routines of DP SDPs are added for readout. It adds a logging function for DP VSC SDP. When receiving video it is very useful to be able to log DP VSC SDP. This greatly simplifies debugging. In order to use a common VSC SDP Colorimetry calculating code on PSR, it uses a new psr vsc sdp compute routine.
Pushed the series to drm-intel-next-queued with Daniel's irc ack for merging the two non-i915 patches that route too.
fi-hsw-4770 now oopses at boot:
/o\
What did I miss? What part about the CI report did I overlook?

You kill machines at boot, CI won't tell you.
This is (or at least was) because the network is shitty enough that we have more spurious failures because the ethernet went into the ether than because of people having killed the machine with their patches for real. Also it's hard to grab logs if the thing doesn't work at all, so cant give you any more data than the above.
Yes this sucks :-/
Cheers, Daniel
