The same code checking if sink supports PSR was spread into 3 tests,
better move it to lib and reuse.
v2: splitted previous patch into this one and the next one(Dhinakaran)

kms_fbcon_fbt was doing its own handling to wait for PSR to get
enabled while it is already available in lib.
v2: splitted previous patch into this one and the previous one(Dhinakaran)

The kernel patch 'drm/i915: Refactor PSR status debugfs' changed the
output of i915_edp_psr_status, so adding support to the new output
here while keeping the support to the old one for a while.

PSR2 will have it own function to detect if is active so we can drop
the sleep state search as it is a PSR2 state.

Pass PSR1/PSR2 as an argument from the caller and handle that in
psr_set(), we can avoid duplicating all this boilerplate code.

The logic looks very similar to PSR1, please see my comment for the
next patch.

those tests will also run for PSR2 if supported by source and sink.

pushing the PSR mode down through the call chain.

I added the PSR2 functions with other names to avoid any
misinterpretation as PSR2 could be active in deep sleep state and doing
selective update and in the states between and in the kms_psr2_su we
need to check both states to properly test.
I'm okay in adding the PSR mode to enable(), disable(), sink_support()
and reuse the internal functions too but in the other functions the
code saved is not worth. What do you think DK?

Selective update testing does not need modifying the behavior of any of
these functions, does it? Both PSR1 and PSR2(non-SU) tests wait until
PSR is in an active state, do some operation and then verify we are out
of the state. Since they follow the same test steps, I believe it is
better to share the interface. We also want kms_fbt_fbcon and
kms_frontbuffer_tracking to setup PSR2, that is another reason
psr_wait_entry()/psr_wait_exit() in the library should handle PSR1 v/s
PSR2 instead of the callers in kms_psr.

Yes but after perform some operation it can keep into a active state in
PSR2 that is why psr_wait_exit() is not a good name. Same for
psr_wait_entry() it is wait entry in deep sleep? or wait entry in PSR
active?

Lets run the same PSR1 basic tests for PSR2 to get PSR2 regressions
faster.

This tests checks if hardware is able to do selective update when
screen changes.
PSR2 don't trigger interruptions and the 'PSR2 SU status' register
is not kept loaded all the times, so it is necessary keep polling
PSR status debugfs until those values are loaded.
When loaded it is compared with the expected value, if matches
the polling is stopped and the test passed otherwise it will
wait until fail_timerfd to expire to fail the test.
v2: Using new SU blocks debugfs output

Does this mean flipping once while polling SU status registers is not
sufficient?

This patch warrants some explanation about the timeouts used and how
they were selected.

What happens if you start this thread and then flip just once? Do you
see the expected block count in debugfs at some instance after the
flip?

Wouldn't it be simpler to flip a fixed number of times?

After a flip in DEEP_SLEEP it will do a PSR exit and PSR active
sequence, it will only do a selective update while in SLEEP state that
is why more than one flip is necessary and it will vary depending of
the values that is set to frames to activate PSR and frames to enter
deep sleep.

The flip timeout is a value to achieve 15hz flips and the error timeout
will be removed as you suggested bellow, I will add a comment when
setting the interval to the flip timerfd.
