This is a note to let you know that I've just added the patch titled drm/i915/bios: Split VBT parsing to global vs. panel specific parts to the 5.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: drm-i915-bios-split-vbt-parsing-to-global-vs.-panel-.patch and it can be found in the queue-5.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ac9fe905031b0de0c092cb8010ed67a6f8d82f9b Author: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Date: Tue May 10 13:42:38 2022 +0300 drm/i915/bios: Split VBT parsing to global vs. panel specific parts [ Upstream commit c2fdb424d32204faf5be29d55f0086b611c94e38 ] Parsing the panel specific data (anything that depends on panel_type) from VBT is currently happening too early. Split the whole thing into global vs. panel specific parts so that we can start doing the panel specific parsing at a later time. v2: Clarify that this is about panel_type (Jani) Split out the leak checks (Jani) Reviewed-by: Jani Nikula <jani.nikula@xxxxxxxxx> Signed-off-by: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Link: https://patchwork.freedesktop.org/patch/msgid/20220510104242.6099-12-ville.syrjala@xxxxxxxxxxxxxxx Stable-dep-of: 607f41768a1e ("drm/i915/dsi: filter invalid backlight and CABC ports") Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/drivers/gpu/drm/i915/display/intel_bios.c b/drivers/gpu/drm/i915/display/intel_bios.c index 5ceabc380808..d5cae64b916b 100644 --- a/drivers/gpu/drm/i915/display/intel_bios.c +++ b/drivers/gpu/drm/i915/display/intel_bios.c @@ -2969,18 +2969,7 @@ void intel_bios_init(struct drm_i915_private *i915) /* Grab useful general definitions */ parse_general_features(i915); parse_general_definitions(i915); - parse_panel_options(i915); - parse_generic_dtd(i915); - parse_lfp_data(i915); - parse_lfp_backlight(i915); - parse_sdvo_panel_data(i915); parse_driver_features(i915); - parse_panel_driver_features(i915); - parse_power_conservation_features(i915); - parse_edp(i915); - parse_psr(i915); - parse_mipi_config(i915); - parse_mipi_sequence(i915); /* Depends on child device list */ parse_compression_parameters(i915); @@ -2999,6 +2988,21 @@ void intel_bios_init(struct drm_i915_private *i915) kfree(oprom_vbt); } +void intel_bios_init_panel(struct drm_i915_private *i915) +{ + parse_panel_options(i915); + parse_generic_dtd(i915); + parse_lfp_data(i915); + parse_lfp_backlight(i915); + parse_sdvo_panel_data(i915); + parse_panel_driver_features(i915); + parse_power_conservation_features(i915); + parse_edp(i915); + parse_psr(i915); + parse_mipi_config(i915); + parse_mipi_sequence(i915); +} + /** * intel_bios_driver_remove - Free any resources allocated by intel_bios_init() * @i915: i915 device instance diff --git a/drivers/gpu/drm/i915/display/intel_bios.h b/drivers/gpu/drm/i915/display/intel_bios.h index 4709c4d29805..c744d75fa435 100644 --- a/drivers/gpu/drm/i915/display/intel_bios.h +++ b/drivers/gpu/drm/i915/display/intel_bios.h @@ -230,6 +230,7 @@ struct mipi_pps_data { } __packed; void intel_bios_init(struct drm_i915_private *dev_priv); +void intel_bios_init_panel(struct drm_i915_private *dev_priv); void intel_bios_driver_remove(struct drm_i915_private *dev_priv); bool intel_bios_is_valid_vbt(const void *buf, size_t size); bool intel_bios_is_tv_present(struct drm_i915_private *dev_priv); diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index 806d50b302ab..e384db157f34 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -9580,6 +9580,7 @@ int intel_modeset_init_noirq(struct drm_i915_private *i915) } intel_bios_init(i915); + intel_bios_init_panel(i915); ret = intel_vga_register(i915); if (ret)
