If crc is disabled, early return when getting crc's. That way, we avoid
reading extra registers within the pflip high irq.

I assumed wrongfully that all relevant functions should be implemented.
Apparently this isn't the case. Demote the print to debug level for now.

From: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com>
Directly editing pipe config outside of formula is error prone
and results in higher clocks being used when splitting.
For this reason we reverted to using bounding box hacking
to split. Since sometimes this erroneusly results in higher dpm
being required we unhack the bounding box and recalculate to allow
dpm0 is possible.
Side effect is we will lose some stutter efficiency
in non dpm0 cases. This is not a big concern since increased stutter
efficiency saves an order of magnitude less power than lower dpm.

What this spin lock is protecting here ? Seems to me it's just a read of
an array element which is always there.
Regarding subsequent remove_timer_handler and timer queue destruction it
seems to me to be obsolete code, I don't think DAL is still using the
timer queue,
so seems to me everything related to it should be removed.
Thanks,
Andrey

Hi Andrey,
I've checked to revert this change and use Alex's change on switching irq destruction sequence and it worked no problem.
You can reject this change if Alex's change is pulled in.
Thanks,
Nick

What this spin lock is protecting here ? Seems to me it's just a read of
an array element which is always there.
Regarding subsequent remove_timer_handler and timer queue destruction it
seems to me to be obsolete code, I don't think DAL is still using the
timer queue,
so seems to me everything related to it should be removed.
Thanks,
Andrey

You guys just need to revert it on dal-dev branch and don't promote to
amd-staging-drm-next.
So NAK for the change.
Thanks,
