Disable the support for odd x pan for even xsize for NV12 format as underrun issue is seen. WA: 16024459452 v2: Replace HSD with WA in commit message [Suraj] Modified the condition for handling odd panning v3: Simplified the condition for checking hsub Using older framework for wa as rev1[Jani] v4: Modify the condition for hsub [Sai Teja] Initialize hsub in else path [Dan] v5: Replace IS_LUNARLAKE with display version. Resolve nitpicks[Jani] v6: Replace -EINVAL with hsub [Suraj] Remove src_w check as not required Signed-off-by: Nemesa Garg <nemesa.garg@intel.com> --- drivers/gpu/drm/i915/display/intel_atomic_plane.c | 5 +++++ 1 file changed, 5 insertions(+)
