Subject: Re: [PATCH v8 4/4] NOTFORMERGE: drm/logicvc: Add plane colorkey support
Date: Wed, 23 Dec 2020 18:31:54 -0500 [thread overview]
Message-ID: <CAKb7UvhgHPkG5Sn-HLdpsFw0R=kATJKUmjSwPSuwviDCk0RGyw@mail.gmail.com> (raw)
In-Reply-To: <oDsOkjfTYKa11LxfNy4LBLqutkVidfFn8--tjQPZj4w9gzCYNTOFglHqxXohsrYqTJ4uDv2xgJNKXPHzgAsACGnCkbKQis95SScGucOb1PI=@emersion.fr>
FWIW this is something I added, hoping it was going to get used at
some point, but I never followed up with support in xf86-video-nouveau
for Xv. At this point, I'm not sure I ever will. I encoded the
"enabled" part into the value with a high bit (1<<24) -- not sure that
was such a great idea. All NVIDIA hardware supports colorkey (and not
actual alpha, until the very latest GPUs - Volta/Turing families),
although my implementation only covers the pre-G80 series (i.e. DX9
and earlier GPUs - pre-2008). Should a determination of usefulness be
reached, it would be easy to implement on the remainder though.
Cheers,
-ilia
