[Intel-gfx] [PATCH 0/2] drm/i915/bios: Rethink LFP data pointer generation

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Turns out the current code for generating the LFP
data pointers doensn't work with certain VBTs, so
switch to just hardcoding the fp_timing table size,
and make the validator a bit more strict just to be
extra safe.

  drm/i915/bios: Validate fp_timing terminator presence
  drm/i915/bios: Use hardcoded fp_timing size for generating LFP data
    pointers

[Intel-gfx] [PATCH 1/2] drm/i915/bios: Validate fp_timing terminator presence

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Validate the LFP data block a bit hardwer by making sure the
fp_timing terminators (0xffff) are where we expect them to be.

I wonder if it would be good to debug log at each of the "return false"
sites in fixup_lfp_data_ptrs() and validate_lfp_data_ptrs(). Anyway,
that's a separate change.

Not sure how much it would help. I suspect one still ends
up decoding the whole hexdump by hand.

[Intel-gfx] [PATCH 2/2] drm/i915/bios: Use hardcoded fp_timing size for generating LFP data pointers

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

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).

What a mess.

Could debug log about missing data ptrs on vbt version < 155, but no
