Re: 2023-08-23 - coreboot Leadership meeting minutes

Hi Hannah

It looks like your information is not up to date.

https://www.phoronix.com/news/Intel-HDMI-2.1-FRL-Linux so hdmi 2.1
upstreaming in Linux began 10 months ago?

Both Linux and
https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/commits/master/ has
support for VBT, which should suffice without a spec. Even coreboot has
limited support for VBT.

It looks like there is no good reason for this blob to be closed source or
did I miss something? The only difference with i915 that has functional
display support is that you use VGA legacy mode in uGOP and not a linear
framebuffer. VGA legacy mode is very old. I think you'll have a hard time
convincing this community that this mode is sensitive NDA only IP that
justifies a blob.

Do you have other technical reasons to justify uGOP being closed source
while Linux has support pretty much a year before the silicon is released?
Maybe we or a search engine can help you out on those too?
