The current scheme for generating the LFP data table pointers (when the block including them is missing from the VBT) expects the 0xffff sequence to only appear in the fp_timing terminator entries. However some VBTs also have extra 0xffff sequences elsewhere in the LFP data. When looking for the terminators we may end up finding those extra sequeneces insted, which means we deduce the wrong size for the fp_timing table. The code then notices the inconsistent looking values and gives up on the generated data table pointers, preventing us from parsing the LFP data table entirely. Let's give up on the "search for the terminators" approach and instead just hardcode the expected size for the fp_timing table. We have enough sanity checks in place to make sure we shouldn't end up parsing total garbage even if that size should change in the future (although that seems unlikely as the fp_timing and dvo_timing tables have been declared obsolete as of VBT version 229).

While executing i915_selftest, wakeref imbalance warning is seen with i915_selftest failure. Currently when Driver is suspended, while doing unregister it is taking wakeref without resuming the device. This patch is resuming the device, if driver is already suspended and doing unregister process. Signed-off-by:

On some systems the panel reports alternate modes with different blanking periods. If the EDID reports them and VBT doesn't tell us otherwise then I can't really see why they should be rejected. So allow their use for the purposes of static DRRS. For seamless DRRS we still require a much more exact match of course. But that logic only kicks in when selecting the downclock mode (or in the future when determining whether we can do a seamless refresh rate change due to a user modeset).

Turns out the MIPI sequence block version number and new block size fields are considered part of the block header and are not included in the reported new block size field itself. Bump up the block size appropriately so that we'll copy over the last five bytes of the block as well. For this particular machine those last five bytes included parts of the GPIO op for the backlight on sequence, causing the backlight no longer to turn back on: Sequence 6 - MIPI_SEQ_BACKLIGHT_ON Delay: 20000 us - GPIO index 0, number 0, set 0 (0x00) + GPIO index 1, number 70, set 1 (0x01) Cc: stable@vger.kernel.org Fixes: e163cfb4 ("drm/i915/bios: Make copies of VBT data blocks") Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/6652Signed-off-by:
