While at it, default the expected child device struct size to sizeof the size rather than a hardcoded value. v2: Fix bit order (David) Cc: Rodrigo Vivi <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Reviewed-by: Rodrigo Vivi <[email protected]> Signed-off-by: Rodrigo Vivi <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit c4fb60b9aba9f939d3f8575df23fd8d5958ec6ed) Signed-off-by: Rodrigo Vivi <[email protected]> --- drivers/gpu/drm/i915/intel_bios.c | 8 +++++--- drivers/gpu/drm/i915/intel_vbt_defs.h | 2 ++ 2 files changed, 7 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_bios.c b/drivers/gpu/drm/i915/intel_bios.c index 4c42cc4b193b..f7f771749e48 100644 --- a/drivers/gpu/drm/i915/intel_bios.c +++ b/drivers/gpu/drm/i915/intel_bios.c @@ -1329,11 +1329,13 @@ parse_general_definitions(struct drm_i915_private *dev_priv, expected_size = LEGACY_CHILD_DEVICE_CONFIG_SIZE; } else if (bdb->version == 195) { expected_size = 37; - } else if (bdb->version <= 197) { + } else if (bdb->version <= 215) { expected_size = 38; + } else if (bdb->version <= 216) { + expected_size = 39; } else { - expected_size = 38; - BUILD_BUG_ON(sizeof(*child) < 38); + expected_size = sizeof(*child); + BUILD_BUG_ON(sizeof(*child) < 39); DRM_DEBUG_DRIVER("Expected child device config size for VBT version %u not known; assuming %u\n", bdb->version, expected_size); } diff --git a/drivers/gpu/drm/i915/intel_vbt_defs.h b/drivers/gpu/drm/i915/intel_vbt_defs.h index e3d7745a9151..98dff6058d3c 100644 --- a/drivers/gpu/drm/i915/intel_vbt_defs.h +++ b/drivers/gpu/drm/i915/intel_vbt_defs.h @@ -412,6 +412,8 @@ struct child_device_config { u16 dp_gpio_pin_num; /* 195 */ u8 dp_iboost_level:4; /* 196 */ u8 hdmi_iboost_level:4; /* 196 */ + u8 dp_max_link_rate:2; /* 216 CNL+ */ + u8 dp_max_link_rate_reserved:6; /* 216 */ } __packed; struct bdb_general_definitions { -- To unsubscribe from this list: send the line "unsubscribe git-commits-head" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
