Ville Syrjälä e3bb355c7d drm/i915/tv: Generate better pipe timings for TV encoder ... To make vblank timestamps work better with the TV encoder let's scale the pipe timings such that the relationship between the TV active and TV blanking periods is mirrored in the corresponding pipe timings. Note that in reality the pipe runs at a faster speed during the TV vblank, and correspondigly there are periods when the pipe is enitrely stopped. We pretend that this isn't the case and as such we incur some error in the vblank timestamps during the TV vblank. Further explanation of the issues in a big comment in the code. This makes the vblank timestamps good enough to make i965gm (which doesn't have a working frame counter with the TV encoder) report correct frame numbers. Previously you could get all kinds of nonsense which resulted in eg. glxgears reporting that it's running at twice the actual framerate in most cases. v2: s/IS_GEN4(dev_priv)/IS_GEN(dev_priv, 4)/ in the comment for consistency Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181112170000.27531-15-ville.syrjala@linux.intel.com Reviewed-by: Imre Deak <imre.deak@intel.com>		2019-01-25 19:09:40 +02:00
