Not quite sure what the best way would be. One idea was to just make sure the timestamp points to more or less the correct point in time. Another idea was to drive the whole loop baed on the timestamps + target refresh rate (ie. wait for event, schedule next flip for event timestamps + whatever time we have left to reach the exected refresh rate). This latter idea I think would catch bugs where the interval between timestamps is correct but the absolute times are not correct (eg. if the timestamps are miscorrected to point fr into the future based on the max vblank length, or too close into the future based on min vblank length). - the busy loop thing I don't think should be needed.

Example: if we have a monitor with vrr range of 40 - 60Hz We'll try to flip with 35, 50 and 65 Hz, and the difference between the two flip timestamps should be within the required threshold from the expected rate. A ~50us threshold is an arbitrary. [*] https://patchwork.freedesktop.org/patch/392037 > - otherwise confirm the timestamps are sensible. Not quite sure what the > best way would be.

Ex. To generate the flips with refresh rate 50Hz (ie. 20000000ns), below is the expected sequence: * Request a flip & wait for flip completion event * Capture the event timestamp to compare * Wait 20000000ns for next flip * Repeat Am I missing something here? > > > > > V2: > > * Rebase > > > > Cc: Manasi Navare <manasi.d.navare@intel.com> > > Cc: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> > > Signed-off-by: Bhanuprakash Modem <bhanuprakash.modem@intel.com> > > --- > > tests/kms_vrr.c | 51 ++++++++++++++++++++----------------------------- > > 1 file changed, 21 insertions(+), 30 deletions(-) > > > > diff --git a/tests/kms_vrr.c b/tests/kms_vrr.c > > index beb06854f..e6edd131f 100644 > > --- a/tests/kms_vrr.c > > +++ b/tests/kms_vrr.c > > @@ -170,7 +170,7 @@ static void set_vrr_on_pipe(data_t *data, enum pipe > pipe, bool enabled) > > { > > igt_pipe_set_prop_value(&data->display, pipe, IGT_CRTC_VRR_ENABLED, > > enabled); > > - igt_display_commit_atomic(&data->display, 0, NULL); > > + igt_display_commit2(&data->display, COMMIT_ATOMIC); > > } > > > > /* Prepare the display for testing on the given pipe. */ > > @@ -208,8 +208,7 @@ static void prepare_test(data_t *data, igt_output_t > *output, enum pipe pipe) > > */ > > igt_pipe_set_prop_value(&data->display, pipe, IGT_CRTC_VRR_ENABLED, > 0); > > > > - igt_display_commit_atomic(&data->display, > > - DRM_MODE_ATOMIC_ALLOW_MODESET, NULL); > > + igt_display_commit2(&data->display, COMMIT_ATOMIC); > > } > > > > /* Waits for the vblank interval.

But in addition I was suggesting that we calculate how long to wait based on the flip event timestamp + whatever extra is needed on top to reach the target frame rate.
