Subject: [PATCH 0/2] Arithmetic ops for Instant/Delta
Date: Thu, 24 Jul 2025 14:54:05 -0400 [thread overview]
Message-ID: <20250724185700.557505-1-lyude@redhat.com> (raw)
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:
