[PATCH 1/3] drm/gem-dma: revert the 8-byte alignment constraint
Posted by Ludovic Desroches 5 days, 7 hours ago
Using drm_mode_size_dumb() to compute the size of dumb buffers introduced
an 8-byte alignment constraint on the pitch that wasn’t present before.
Let’s remove this constraint, which isn’t necessarily required and may
cause buffers to be allocated larger than needed.
