[PATCH] drm/i915/dsc: Fix pic_width readout

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

 



pic_width when written into the PPS register is divided by the no.
of vdsc instances first but the actual variable that we compare it
to does not change i.e vdsc_cfg->pic_width hence when reading the
register back for pic_width it needs to be multiplied by
num_vdsc_instances rather than being divided.
