For some reason xe and i915 each have an identical (fortunately) copy of intel_fbdev_fb.h. The xe copy actually only gets included by xe's intel_fbdev_fb.c, and the i915 copy by everyone else, include intel_fbdev.c which is the actual caller of the functions declared in the header. This means the xe and i915 headers are free to define/declare completely incompatible things and the build would still succeed as long as the symbol names match. That is not a good thing, so let's nuke xe's copy of the header so that everyone will use the same header, and be forced to agree on the same API/ABI. Signed-off-by:

Define the contents of VBT block 253 (PRD Table). Unfortunately the block has two definitions, with the cutoff supposedly happening on ICL vs. TGL. Also according to some notes it might be that the VBIOS (if that's still a thing) still uses the old definition even on TGL+. Quite the mess. Signed-off-by:

Declare that VBT block 252 is the "int15 hook". This is some VBIOS only juju so don't bother with a full definition. Signed-off-by:

Define the contents of the obsolete VBT block 55 (Compression Parameters). This was some early attempt at defining the compression parameters. However the spec says: "This block is obsolete and should not be consumed for any compression programming." Block 56 is the replacement that should actually be used. So let's just name the obsolete old block but not even bother defining the contents. Signed-off-by:

Define the contents of VBT block 50 (MIPI). This was some easly attempt at a MIPI DSI stuff. I'm not sure this was ever actually used (I certainly don't have any VBTs with this block), but here's some kind of definition for it anyway. Signed-off-by:

Define the contents of VBT block 57 (Vswing PreEmphasis Table). The contents is highly platform specific. The columns of the table corresponding to some set of PHY/etc registers. The rows corresponding to all legal vswing+pre-emphasis combinations (ie. should be 10 rows in each table). And each table corresponds to a platform specific (mostly undocumented) mapping based on link rate/eDP low-vswing/etc. parameters. Signed-off-by:

Define the contents of VBT block 25 (SDVO LVDS PPS). Not 100% sure about the order of the fields as this is not documented in the VBT spec anymore, but this order matches what is included as part of the power sequencing SDVO commands (struct sdvo_panel_power_sequencing). Also the real world VBT data I have looks OK with this definition. Signed-off-by:

Define the contenst is VBT blocks 19,30,32 (Display Configuration Removal Table) contents. There are three variants of this block: pre-IVB, IVB, HSW+, with each having slightly different entries. Curiously many HSW/BDW machines seem to have both the IVB and HSW+ variants in their VBTs simultanously. No idea why. Signed-off-by:

For some reason ALM VBT has two dot clock override tables. One as the normal block 15 and a second one as block 9. The table in block 9 has no row_size/num_rows information. On my Fujitsu Lifebook S6010 only the block 9 table has actual data in it. Block 15 is present but all zeroes. Signed-off-by:

Define the contents of VBT block 15 (Dot Clock Override Table) The contents were reverse engineered by intuition. The gen2 stuff seems solid as I can verify that against real world VBT data. The gen3 stuff less so as all the gen3+ VBTs I have just filla the entire block with zeroes. Signed-off-by:

Define the contents of VBT block 10 (Mode Removal Table). There seem to be two variants: - 8 byte entries for desktop systems - 10 byte entries for mobile systems, with the extra panel_flags being a bitmask of LFPs It seems starting from HSW only the mobile variant is used anymore. Signed-off-by:

Define the contents for VBT blocks: - Block 6 (Extended MMIO Register Table) - Block 7 (IO Software Flag Table) - Block 8 (MMIO SWF Register Table) All of these use the same basic layout, with two known variants: - data_access_size==0xce -> offset,value tuples are u8,u8 - data_access_size==0x02 -> offset,value tuples are u32,u32 Signed-off-by:

Define the contents of VBT block 5 (Generic Mode Table). Details were mostly gleaned from some VBIOS sources. There are apparently two variants of the block: ALM only vs. MGM, defined here as bdb_generic_mode_table_alm and bdb_generic_mode_table_mgm. And those are the only two platforms where I've seen this block. Signed-off-by:

Define the contents of VBT block 4 (Mode Support List). Slightly crazy layout with a variable length list at the start, followed by the length of said list. No real idea what these "Intel mode numbers" really are. What I see in real world VBTs seems to be always the same list of 26 numbers, ranging between 0x30 and 0x84. Signed-off-by:

Child device 0x2 used to be "TV" until redefined to mean EFP5 in version 215. Add a define for the old meaning as well. Technically it was probably deprecated a lot before version 215 since native TV encoders were last seen on CTG, and SDVO was fully gone by HSW. So something like "???-164" might also be a reasonable way to document this, but no real harm in saying "???-214" since nothing else presumably occupied that bit in the meantime. Signed-off-by:

The SDVO LVDS blocks are specifically about LVDS, so stick to naming that reflects that. This also makes the names match the spec. Signed-off-by:
