Provide the lower level code for PIPEDMC based flip queue.
We'll use the so called semi-full flip queue mode where the
PIPEDMC will start the provided DSB on a scanline a little
ahead of the vblank. We need to program the triggering scanline
early enough so that the DSB has enough time to complete writing
all the double buffered registers before they get latched (at
start of vblank).
The firmware implements several queues:
- 3 "plane queues" which execute a single DSB per entry
- 1 "general queue" which can apparently execute 2 DSBs per entry
- 1 vestigial "fast queue" that replaced the "simple flip queue"
on ADL+, but this isn't supposed to be used due to issues.
But we only need a single plane queue really, and we won't actually
use it as a real queue because we don't allow queueing multiple commits
ahead of time. So the whole thing is perhaps useless. I suppose
there migth be some power saving benefits if we would get the flip
scheduled by userspace early and then could keep some hardware powered
off a bit longer until the DMC kicks off the flipq programming. But that
is pure speculation at this time and needs to be proven.
The code to hook up the flip queue into the actual atomic commit
path will follow later.
TODO: need to think how to do the "wait for DMC firmware load" nicely
need to think about VRR and PSR
etc.
v2: Don't write DMC_FQ_W2_PTS_CFG_SEL on pre-lnl
Don't oops at flipq init if there is no dmc
v3: Adapt to PTL+ flipq changes (different queue entry
layout, different trigger event, need VRR TG)
Use the actual CDCLK frequency
Ask the DSB code how long things are expected to take
v3: Adjust the cdclk rounding (docs are 100% vague, Windows
rounds like this)
Initialize some undocumented magic DMC variables on PTL
v4: Use PIPEDMC_FQ_STATUS for busy check (the busy bit in
PIPEDMC_FQ_CTRL is apparently gone on LNL+)
Based the preempt timeout on the max exec time
Preempt before disabling the flip queue
Order the PIPEDMC_SCANLINECMP* writes a bit more carefully
Fix some typos
v5: Try to deal with some clang-20 div-by-zero false positive (Nathan)
Add some docs (Jani)
