This patch adds helpers for calculating the maximum compressed BPP supported with small joiner. This also adds a helper for calculating the slice count in case of small joiner. These are inside intel_dp since they take into account hardware limitations. v6: * Take mode_clock and mode_hdisplay as input arguments so that this can be called in intel_dp_mode_valid (Manasi) v5: * Get the max slice width from DPCD * Check against Min_Slice_width of 2560 (Anusha) v4: * #defines for PPR in slice count helper (Gaurav) v3: * Simply logic for bpp (DK) * Limit the valid slice count by max supported by Sink (Manasi) v2: * Change the small joiner RAM buffer constant as bspec changed (Manasi) * rename it as SMALL_JOINER since we are not enabling big joiner yet (Anusha) Cc: Gaurav K Singh <gaurav.k.singh@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: Anusha Srivatsa <anusha.srivatsa@intel.com> Reviewed-by: Gaurav K Singh <gaurav.k.singh@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181031001923.31442-5-manasi.d.navare@intel.com |
