[PATCH i-g-t 3/6] lib/igt_kms: Rework plane properties to be more atomic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In the future I want to allow tests to commit more properties,
but for this to work I have to fix all properties to work better
with atomic commit. Instead of special casing each
property make a bitmask for all property changed flags, and try to
commit all properties.
