The function descriptions are optional and have not yet been added to the DMC wakelock code, so we shouldn't try to use it. Since this is a regression, remove the kernel-doc entry for DMC wakelocks for now. The proper documentation will be added in a future patch.

Nothing in xe needs xe->sb_lock. None of the i915 display code using ->sb_lock gets built with xe, and in any case that would be wrong as xe uses gt->pcode.lock for this. Acked-by:

We use a mix of 'intel_fb' vs. 'ifbdev->fb' in the same function. Both should be pointing at the same thing. Make things less confusing by just getting existing fb from 'ifbdev->fb' at the start and then sticking with the local 'fb' (renamed from the 'intel_fb') until the very end. v2: rebase Signed-off-by:

WA_14020863754: Corner case with Min Hblank Fix can cause audio hang Issue: Previously a fix was made to avoid issues with extremely small hblanks, called the "Min Hblank Fix". However, this can potentially cause an audio hang. Workaround : During "Audio Programming Sequence" Audio Enabling - When DP mode is enabled Set mmio offset 0x65F1C bit 18 = 1b, before step #1 "Enable audio Presence Detect" During "Audio Programming Sequence" Audio Disabling - When DP mode is enabled Clear mmio offset 0x65F1C bit 18 = 0b, after step #6 "Disable Audio PD (Presence Detect)" If not clearing PD bit, must also not clear 0x65F1C bit 18 (leave = 1b) v2: Update the platform checks (Jani Nikula) v3: Limited the WA to LNL and BMG, added a helper (Matt Roper) v4: Updated the bit naming, fixed redundant if statement Signed-off-by:

Be a bit more consistent in our use of integer types in the fb related calculatiosn. u32 we generally only use for ggtt offsets and such, and everything else can be regular (unsigned) ints. There's also an overabundance of consts for local variables in skl_check_main_surface() which is not something we generally do. So get rid of those while at it. Signed-off-by:

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:

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:
