[PATCH 0/2] Arithmetic ops for Instant/Delta

Posted by Lyude Paul 2 months, 1 week ago

When rebasing RVKMS against my hrtimer additions, which themselves were
rebased against Fujita's recent work for introducing Instant/Delta, I
needed to reintroduce the ability to perform some of the arithmetic that
rvkms uses for vblank emulation - so, this commit introduces such
arithmetic.

Example usage:
