Had to do some digging for this one. So the story is that the field was introduced in 216 but then they totally changed the meaning of the bits in 230. See parse_bdb_216_dp_max_link_rate() vs. parse_bdb_230_dp_max_link_rate(). But naturally the current version of the spec totally fails to mention this. Sigh. The GLK comment originally said CNL (it got changed during mass rename when CNL stuff was dropped), and that was just based on a note in the spec at the time that said the field is valid for CNL+. Whether that actually included GLK or not is not at all clear. Also currently we parse this for everything so it's not super obvious if we're accidentlaly parsing it on platforms where it should not be used. But that should actually be fine since the value should then be 0 which either means 8.1Gbps or "no limit" which should not therefore impose any accidental limit on anything. I should probably put some of that into the commit message for posterity... > but anyway the 216+ includes the 230, so it looks okay. > > for everything else I just relied on what was already in the code > and didn't check the VBT itself, but feel free to use: > > Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Thanks. > > > > > + u8 dp_usb_type_c:1; /* 195+ */ > > + u8 tbt:1; /* 209+ */ > > + u8 flags2_reserved:2; /* 195+ */ > > + u8 dp_port_trace_length:4; /* 209+ */ > > + u8 dp_gpio_index; /* 195+ */ > > + u16 dp_gpio_pin_num; /* 195+ */ > > + u8 dp_iboost_level:4; /* 196+ */ > > + u8 hdmi_iboost_level:4; /* 196+ */ > > + u8 dp_max_link_rate:3; /* 216+ */ > > + u8 dp_max_link_rate_reserved:5; /* 216+ */ > > } __packed; > > > > struct bdb_general_definitions { > > @@ -690,18 +704,18 @@ struct bdb_edp { > > u32 sdrrs_msa_timing_delay; > > > > /* ith bit indicates enabled/disabled for (i+1)th panel */ > > - u16 edp_s3d_feature; /* 162 */ > > - u16 edp_t3_optimization; /* 165 */ > > - u64 edp_vswing_preemph; /* 173 */ > > - u16 fast_link_training; /* 182 */ > > - u16 dpcd_600h_write_required; /* 185 */ > > - struct edp_pwm_delays pwm_delays[16]; /* 186 */ > > - u16 full_link_params_provided; /* 199 */ > > - struct edp_full_link_params full_link_params[16]; /* 199 */ > > - u16 apical_enable; /* 203 */ > > - struct edp_apical_params apical_params[16]; /* 203 */ > > - u16 edp_fast_link_training_rate[16]; /* 224 */ > > - u16 edp_max_port_link_rate[16]; /* 244 */ > > + u16 edp_s3d_feature; /* 162+ */ > > + u16 edp_t3_optimization; /* 165+ */ > > + u64 edp_vswing_preemph; /* 173+ */ > > + u16 fast_link_training; /* 182+ */ > > + u16 dpcd_600h_write_required; /* 185+ */ > > + struct edp_pwm_delays pwm_delays[16]; /* 186+ */ > > + u16 full_link_params_provided; /* 199+ */ > > + struct edp_full_link_params full_link_params[16]; /* 199+ */ > > + u16 apical_enable; /* 203+ */ > > + struct edp_apical_params apical_params[16]; /* 203+ */ > > + u16 edp_fast_link_training_rate[16]; /* 224+ */ > > + u16 edp_max_port_link_rate[16]; /* 244+ */ > > } __packed; > > > > /* > > @@ -710,7 +724,7 @@ struct bdb_edp { > > > > struct bdb_lvds_options { > > u8 panel_type; > > - u8 panel_type2; /* 212 */ > > + u8 panel_type2; /* 212+ */ > > /* LVDS capabilities, stored in a dword */ > > u8 pfit_mode:2; > > u8 pfit_text_mode_enhanced:1; > > @@ -733,9 +747,9 @@ struct bdb_lvds_options { > > /* LVDS backlight control type bits stored here */ > > u32 blt_control_type_bits; > > > > - u16 lcdvcc_s0_enable; /* 200 */ > > - u32 rotation; /* 228 */ > > - u32 position; /* 240 */ > > + u16 lcdvcc_s0_enable; /* 200+ */ > > + u32 rotation; /* 228+ */ > > + u32 position; /* 240+ */ > > } __packed; > > > > /* > > @@ -756,7 +770,7 @@ struct lvds_lfp_data_ptr { > > struct bdb_lvds_lfp_data_ptrs { > > u8 lvds_entries; > > struct lvds_lfp_data_ptr ptr[16]; > > - struct lvds_lfp_data_ptr_table panel_name; /* 156-163?
