[v8 0/5] enhanced edid driver compatibility

[v8 0/5] enhanced edid driver compatibility

[Lee Shawn C]

Support to parse multiple CEA extension blocks and HF-EEODB to
extend drm edid driver's capability.

v4: add one more patch to support HF-SCDB
v5: HF-SCDB and HF-VSDBS carry the same SCDS data. Reuse
    drm_parse_hdmi_forum_vsdb() to parse this packet.
v6: save proper extension block index if CTA data information
    was found in DispalyID block.
v7: using different parameters to store CEA and DisplayID block index.
    configure DisplayID extansion block index before search available
    DisplayID block.
v8: revert patch [v7 2/5] change.
    And check cea pointer return from drm_find_cea_extension().
    If drvier got the same cea pointer then exit this routine.

Lee Shawn C (5):
  drm/edid: seek for available CEA block from specific EDID block index
  drm/edid: parse multiple CEA extension block
  drm/edid: read HF-EEODB ext block
  drm/edid: parse HF-EEODB CEA extension block
  drm/edid: check for HF-SCDB block

[v8 1/5] drm/edid: seek for available CEA block from specific EDID block index

[Lee Shawn C]

drm_find_cea_extension() always look for a top level CEA block. Pass
ext_index from caller then this function to search next available
CEA ext block from a specific EDID block pointer.

Try to find and parse more CEA ext blocks if edid->extensions

v2: split prvious patch to two. And do CEA block parsing
    in this one.
v3: simplify this patch based on previous change.
v4: refine patch v3.
v5: revert previous change.
    And check cea pointer return from drm_find_cea_extension().

[v8 3/5] drm/edid: read HF-EEODB ext block

[Lee Shawn C]

According to HDMI 2.1 spec.

"The HDMI Forum EDID Extension Override Data Block (HF-EEODB)
is utilized by Sink Devices to provide an alternate method to
indicate an EDID Extension Block count larger than 1, while
avoiding the need to present a VESA Block Map in the first
E-EDID Extension Block."

It is a mandatory for HDMI 2.1 protocol compliance as well.
This patch help to know how many HF_EEODB blocks report by sink
and read allo HF_EEODB blocks back.

v2: support to find CEA block, check EEODB block format, and return
    available block number in drm_edid_read_hf_eeodb_blk_count().

[Intel-gfx] [v8 3/5] drm/edid: read HF-EEODB ext block

[Lee Shawn C]

According to HDMI 2.1 spec.

"The HDMI Forum EDID Extension Override Data Block (HF-EEODB)
is utilized by Sink Devices to provide an alternate method to
indicate an EDID Extension Block count larger than 1, while
avoiding the need to present a VESA Block Map in the first
E-EDID Extension Block."

It is a mandatory for HDMI 2.1 protocol compliance as well.
This patch help to know how many HF_EEODB blocks report by sink
and read allo HF_EEODB blocks back.

v2: support to find CEA block, check EEODB block format, and return
    available block number in drm_edid_read_hf_eeodb_blk_count().

It still just boggles my mind that they've implemented something like
this. They cite avoiding the EDID Block Map as the rationale... but it's
been optional since E-EDID structure v1.4, published in 2006. 15+ years
ago.

Can anyone tell me a sane reason for this? What does it provide that
E-EDID 1.4 does not? Do they want to use E-EDID v1.3 with this? Why?

Oh, and the main problem with the whole thing, and this implementation?

If you have a struct edid *, there's no way way to tell if whoever
allocated the memory or copied the block was actually HF-EEODB aware.

Basically we'd have to audit every single piece of EDID handling code
across all drivers to see if they handle HF-EEODB properly. If we don't,
it's a question of time a struct edid * with HF-EEODB but no memory
allocated for the extensions gets passed to a function that understands
it, and overflows the buffer.

Simon and Daniel also tell me on IRC we can't just modify the base block
extension count to match HF-EEODB to dodge the problem, because the EDID
gets exposed to userspace.

I'm not familiar how the EDID blob gets exposed to user-space. If the
EDID data gets copied when creating the blob, and the blob is created
before the kernel mutates the EDID to accomodate for HF-EEODB, then
this proposal might still be workable.

You'd still end up with tracking separate copies of the EDID, which is
not necessarily easier. There are almost 70 calls to update the
connector EDID property that gets exposed to userspace, and the call
sites would need to know which copy to pass.

Looks to be pretty much the same approach as the DPCD extended
receiver cap mess we already have to deal with.

So I presume this is a hack to avoid breaking some garbage source
devices that explode when they see too many extension blocks,
or something along those lines.

[v8 5/5] drm/edid: check for HF-SCDB block

[Lee Shawn C]

Find HF-SCDB information in CEA extensions block. And retrieve
Max_TMDS_Character_Rate that support by sink device.

v2: HF-SCDB and HF-VSDBS carry the same SCDS data. Reuse
    drm_parse_hdmi_forum_vsdb() to parse this packet.
