Following up what was done in commit 804f46885317 ("drm/i915/psr: Set
"SF Partial Frame Enable" also on full update") and also setting
partial frame enable when psr_force_hw_tracking_exit() is called.

Instead of exit PSR when a frontbuffer invalidation happens, we can
enable the PSR2 selective fetch continuous full frame, that will keep
the panel updated like PSR was disabled but without keeping PSR active.
So as soon as the frontbuffer flush happens we can disable the
continuous full frame and start to do selective fetches much quicker
than the path that would enable PSR, that will wait a few frames
to actually activate PSR.
Also this approach has proven to fix some glitches found in Alderlake-P
when there are a lot of invalidations happening together with page
flips.
Some may ask why it is writing to CURSURFLIVE(), it is because
that is the way that hardware team provided us to poke display to
handle PSR updates, and it is being used since display 9.

Hello Jose,
See my comments below.

with keeping PSR active? I don't think it's like PSR was disabled. New
full frame is updated only via atomic commit. Having PSR disabled new
full frame is updated all the time as PSR wasn't existing at all.

Generic comments:
Current logic is to disable psr2 in invalidate callback and start
sending fullframe updates on every vblank period. This is done until
flush callback where psr2 is re-enabled. Intention is to update
possible frontbuffer writes between invalidate/flush instantly.
Now you are changing the logic to update one full frame when
frontbuffer write starts (_psr_invalidate_handle) and another one when
it stops (_psr_flush_handle) without disabling psr at all. Have I
understood your patch correctly?
Propably we wont notice this change as we have these invalidate/flush
calls scattered around in the code. Also parallel atomic commits are
triggering updates. In theory we could observe latency in updates
between invalidate/flush? Do we care? What do you think?
Do we need to send update in invalidate at all? Isn't that usually
called before doing any frontbuffer writing? I.e. we would be sending
frame that is already in RFB?

Should we actually now consider taking psr->lock here?

Should we still trigger the update using CURSURFLIVE? Or do we need
that at all in the first place?

So these two register writes here are triggering one full frame update.
and leaving full frame update bit set so that coming updates are also
full frame. Did I understood it correctly?
As invalidate is called before frontbuffer is writen: Isn't it actually
re-updating same frame which is already supposed to be in panel RFB?

As you are using this prev_busy_frontbuffer_bits only to check if
"continuos full frame" is enabled and nothing else: Maybe you could
just name it as it is e.g. bool cff_enabled or bool
continuous_full_frame or...same comment in _psr_invalidate_handle. This
would allow you to drop couple of comments.

It is not enabling the one full frame, it is enabling the continuous full frame so at every vblank panel will be updated until this bit cleared.

I don't think we need. mmio writes are syncronized, this will never set continuous full frame and will only clear su region start and end.
Also this function is called from a time sensitive section if we spend too much time here it will cause vblank evasion warnings.

prev_busy_frontbuffer_bits or a bool anyway works for me, if you think is easier to understand I can change to bool.

There is comment in bspec stating otherwise (55229). I think it is
important to clarify so that we really understand what this WA is doing
and to avoid hiding the issue just for this specific case.
Currently I'm suspecting that "SF Continuous Full Frame" just
configures next selective update to full frame and then write to
CURSURFLIVE triggers flip which is sending that full frame (only one
frame). Updates between invalidate and flush are just depending if
there are flips in between. After getting this clarified we can
properly review this WA patch.

Ok, how about hitting flush/invalidate in between read/write in

To my opinion it actually helps understanding the code. This was just
idea. I'm not insisting to change if you think current one is better.
