[igt-dev] [PATCH i-g-t 0/3] Unify HDMI audio EDID generation

HDMI audio EDIDs are used in both HDMI injection tests and Chamelium audio
tests.

[igt-dev] [PATCH i-g-t 1/3] lib/tests/igt_edid: introduce EDID sanity checks

[Simon Ser]

The idea is to make sure we don't completely break EDIDs by performing some
basic sanity-checking in lib tests.

The test currently only checks the base and alt EDIDs. More EDIDs will be added
in the future: HDMI audio, 4K, 3D and so on.

The logic is mostly borrowed from lib/tests/igt_hdmi_inject.c. This patch is
part of the "let's unify igt_edid and igt_hdmi_inject" series.

[igt-dev] [PATCH i-g-t 2/3] lib/igt_edid: add support for Speaker Allocation Data blocks

[Simon Ser]

Speaker Allocation Data blocks describe which speakers are present in the
display device.

This block is required to make DisplayPort audio work.

Yes, "Speaker Allocation Data" is the official name.

EDID allows a variable number of these, so this struct has variable
length. The array must have a zero size otherwise sizeof-based
computations will be off (each of the members of the union have a
different size). The idea is to allow indexing any of these from the
end of the header block.

Alternatively, in all places where we access these fields we could cast
the edid_cea_data_block to a char *, then add sizeof(struct
edid_cea_data_block), then cast to a struct cea_speaker_alloc *. This
sounds a little annoying to write and to read, though.

I see... Well, sounds like an acceptable reasoning. Is it documented on
top of the union already?

[igt-dev] [PATCH i-g-t 3/3] lib/igt_kms: introduce igt_kms_get_hdmi_audio_edid

[Simon Ser]

This new function uses igt_edid to generate an EDID suitable for testing HDMI
audio. It's imported from kms_chamelium with minor edits, it's used there and
in kms_hdmi_inject. A (unexported for now) generate_hdmi_audio_edid function
enables generation of EDIDs with arbitrary SAD and speaker blocks.

This obsoletes kmstest_edid_add_audio.

The sanity check for the HDMI audio EDID has been moved from
lib/tests/igt_hdmi_inject.c to lib/tests/igt_edid.c.
