Just use 0x1fff always, or even extend both masks to 0xffff. Looks like i9xx_get_initial_plane_config() is also missing a bit or two, which should be fixed with a separate patch. > > val = I915_READ(PLANE_STRIDE(pipe, plane_id)); > -- > 2.19.1

Yes I double checked, all the extra bits (31:28) for older platforms are MBZ so yes I will just use 0xffff as the mask then > > Looks like i9xx_get_initial_plane_config() is also missing a bit or two, > which should be fixed with a separate patch.

On ICL+, the max supported plane height is 4320, so bump it up To support 4320, we need to increase the number of bits used to read plane_height to 13 as opposed to older 12 bits. v2: * ICL plane height supported is 4320 (Ville) * Add a new line between max width and max height (Jose) Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> --- drivers/gpu/drm/i915/display/intel_display.c | 22 ++++++++++++++++++-- 1 file changed, 20 insertions(+), 2 deletions(-)
