[Intel-gfx] [PATCH 0/8] SKL/KBL watermark fixes

[Paulo Zanoni]

Hi

This series is the result of me comparing the code against BSpec. It
doesn't solve any particular problem I was seeing, but there's enough
changes that this code could potentially change the watermarks values
for most machines. Maybe this will fix somebody's underrun? Even if it
doesn't, we should still have a code that matches the specification
unless there's a big justification.

I still didn't finish reviewing everything and there's at least one
workaround that we seem to be missing, but let's try to get these
patches merged first.

Thanks,
Paulo
