I wasn't subscribed at the time (else I'd follow up to the right
message), but I was recently pointed to this patch series:
It seems like it should do the right thing according to my manual dump
of the VBT on some laptops I've got handy, though I've not tried it yet.
Some comments though:
- HDMI_CLASS/INT_DP_CLASS and the associated PORT and DVO defines should
really live in intel_bios.h next to the other device types.
- TV seems to be device type 1009, and LFP to be 1022, but those aren't
in intel_bios.h. Would be nice to resync that with the BIOS sources.
- The capabilities field in child_device_config seems to be the only
field there that's all of: interesting, sometimes non-zero, non-obvious,
and undocumented. I've seen values of 0, 0x08 and 0x20 so far; what do
these bits mean?
