The graphics group had another get together via hangouts. Here's the less
tardy meeting minutes from that. The next meeting is December 5.
Warner
P.S. Sorry for using 11/7 for the November 7th meeting... I forget it's an
international audience sometimes.
2018-11-21: Next meeting
-
Drm-legacy, status update from FreeBSD 12
-
Nothing new to report, mostly working. We need more docs, but this is
likely as good as it gets. It requires the xf86-video-ati-legacy DDX =
when
using ATI/AMD cards. May also need to add a note about the
=E2=80=98video=E2=80=99 group so
they can use the acceleration. This is true for drm-* and is importan=
t to
get good performance.
-
Drm-stable, drm-next and default version in 12
-
What=E2=80=99s today drm-next will be the version for 11.2. (we can r=
etire
drm-stable)
-
Is drm-devel stable enough for 12.0? 4.16 will be the default version
for 12, 4.11 will be backup 12.0. Can=E2=80=99t guarantee 4.11 will w=
ork for the
life of the 12 branch, but will work for a transition period around t=
he
release.
-
Different drm ports for different FreeBSD versions
-
As the number of releases supported by drm drivers increase we need
to reduce maintenance burden. It=E2=80=99s not manageable to have the=
same code
branch build for all releases. (Johannes L)
-
Manage this by creating a 4.16-12.0 (which is locked), 4.16-13. If
changes are needed for 12.1 when it comes, we make a 4.16-12.1 branch=
.
-
Only drm-devel for current to keep support load manageable.
-
For each version cut one version. Drm-devel for current. Latest
changes land in drm-experimental that we iterate on until it=E2=80=99=
s ready to
become the next drm-devel.

-
Release notes
-
Needs to be written. Niclas to do it, the rest to review. Will be put
on github for review, then marshalled in to FreeBSD.
-
Bumping llvm version in mesa
-
Bumping it to llvm70, running on one laptop for a few hours and
things aren=E2=80=99t terrible. More testing needed, especially on AM=
D. Make
go/nogo call next graphics meeting, or sooner.

-
Input stack - progress update
-
Not much to report, not much work done on it. Hopes progress made
this weekend.
-
Evdev in GENERIC
-
Committed i386, amd64, powerpc and powerpc64 (i386, amd64 merged to
12).
-
Other architectures possible, but users need to contact Niclas to get
them added.
-
I386 and ppc64 support in drm-devel-kmod
-
Ppc64: Linux ioremap takes a raw resource, so we needed a bus helper
to do the translations on ppc64=E2=80=99s different domains. Changes =
need to be
upstreamed and reconciled with Baldwin=E2=80=99s proposals. Also need=
some memory
barriers needed.
-
I386 support in and working, as far as we know.
-
Plan to turn off build by default for i386 and amd64 in the next week
in 13.0. Sometime after the first of the year we=E2=80=99ll trim thin=
gs
further in
head.
-
Documentation and new wiki page
-
https://wiki.freebsd.org/Graphics2
-
New blog here https://freebsddesktop.github.io/
-
General reorganization to help people understand more easily. This
includes a FAQ with the gotchas like DDX matching, tables for support=
ed
devices, etc. This is the user-facing documentation.
-
Will need to have a developer=E2=80=99s resource to help people find =
things,
do testing, understand the general state of things.
-
Should be in good enough state before 12.0 RELEASE to have the
cut-over done. We=E2=80=99ll move old stuff away and move Graphics2 -=
> Graphics
when over the weekend sometime.
-
Testing
-
CI compile testing to make sure that we still build on each of the
supported 12.x releases. Suggested loading modules to catch missing
symbols, etc.
-
Further discussions deferred to next meeting.
-
Mesa 18.3.0
-
Defer until next meeting. Still in RC phase and patches are
available. Needs more testing and we=E2=80=99ll talk about next time.

Quarterly status report
-
Started new branch in the freebsddesktop repo so we can keep a
=E2=80=98ticker=E2=80=99 going of important things so we can remember=
come January when
it=E2=80=99s time to do a report. Can be found here:
