[igt-dev] [PATCH i-g-t v2 3/5] tests/kms_flip: Request the initial vbl count with RELATIVE instead of ABSOLUTE

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Asking for the initial vblank count by specifying and absolute vblank count of 0
doesn't make much sense. Switch to a relative query instead.

v2: Drop the NEXTONMISS (Daniel)
v3: Put back the NEXTONMISS (Chris)
