Number of DSC slices can be shown in the DSC debugfs so that test can take a call whether the configuration can support forcing bigjoiner/ultrajoiner. v2: used intel_dp_is_edp() as the parameter to drm_dp_dsc_sink_max_slice_count() (Jani N) Reviewed-by: Nemesa Garg <nemesa.garg@intel.com> (v1) Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/3387 Signed-off-by: Swati Sharma <swati2.sharma@intel.com> --- drivers/gpu/drm/i915/display/intel_display_debugfs.c | 2 ++ 1 file changed, 2 insertions(+)
