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:

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:

Xe2_HPD has different offsets for C20 PHY SRAM configuration context location. Use the display version to select the right address. Note that Xe2_LPD uses the same C20 SRAM offsets used by Xe_LPDP (i.e. MTL's display). According to the BSpec, currently, only Xe2_HPD has different offsets, so make sure it is the only display using them in the driver. v2: * Redesigned how the right offsets are selected for different display IP versions. v3: Fix white space error(RK) Bspec: 67610 Cc: Clint Taylor <Clinton.A.Taylor@intel.com> Cc: Gustavo Sousa <gustavo.sousa@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Signed-off-by:

Display code uses IS_BATTLEMAGE macro but the platform support doesn't exist in i915. So fake IS_BATTLEMAGE macro defined to enable building i915 code. We should make sure the macro parameter is used in the always-false expression so that we don't run into "unused variable" warnings from i915 builds if the IS_BATTLEMAGE() check is the only place the i915 pointer gets used in a function. While we're at it, also update the IS_LUNARLAKE macro to include the parameter in the false expression for consistency. Signed-off-by:
