VBT reuses a bunch of EDID data structures. Flag those as such for clarity. I chose "bdb_edid_" as the namespace for these. Signed-off-by:

DEVICE_HANDLE_EFP4 has actually been in use since the very beginning, or at least something has been occupying that bit because old VBTs actually use it, and it definitely looks to be about external displays given how its used. So let's ignore what the current spec claims and remove the misleading version number comment. Signed-off-by:

Starting BDB version 239, hdr_dpcd_refresh_timeout is introduced to backlight BDB data. Commit 70003456 ("drm/i915/bios: Define more BDB contents") updated the backlight BDB data accordingly. This broke the parsing of backlight BDB data in VBT for versions 236 - 238 (both inclusive) and hence the backlight controls are not responding on units with the concerned BDB version. backlight_control information has been present in backlight BDB data from at least BDB version 191 onwards, if not before. Hence this patch extracts the backlight_control information for BDB version 191 or newer. Tested on Chromebooks using Jasperlake SoC (reports bdb->version = 236). Tested on Chromebooks using Raptorlake SoC (reports bdb->version = 251). v2: removed checking the block size of the backlight BDB data [vsyrjala: this is completely safe thanks to commit e163cfb4 ("drm/i915/bios: Make copies of VBT data blocks")] Fixes: 70003456 ("drm/i915/bios: Define more BDB contents") Cc: stable@vger.kernel.org Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Nirmoy Das authored
Display surfaces can be tagged as transient by mapping it using one of the various L3:XD PAT index modes on Xe2. The expectation is that KMD needs to request transient data flush at the start of flip sequence to ensure all transient data in L3 cache is flushed to memory. Add a routine for this which we can then call from the display code. v2: rebase(RK) Signed-off-by:
