FreeBSD 13.0-BETA2: Xorg slow

[Maurizio Vairani]

I have successfully upgraded the FreeBSD (actually NomadBSD) installed on a
Lenovo ThinkPad T450 from 12.2-RELEASE-p3. After upgrading all packages I
have replaced the package graphics/drm-fbsd12-kmod with
graphics/drm-fbsd13-kmod. After rebooting the laptop  works but the  Xorg
server is slow because it uses a lot of CPU: moving a window around the
screen uses 100% of the CPU.


Regards,

Maurizio

Re: stable/12 git -> svn mirror delayed

[Warner Losh]

I've done a dry-run that looks good (at first blush, I still need to look
at it in more detail). I've put a workaround into the conversion script
that will fix this issue (and any others that are just like it that slip
through), but is definitely hackish and not generic for all possible ways
that a merge commit could land. When I'm satisfied, I'll have the automated
mirroring re-enabled and we should be good, though it may be a few hours
due to time zones, etc.

A note to this thread when it is committed to rewleng or stable would be
greatly appreciated.  The time to download and unpack a large port distfile
(e.g. firefox) is painful. I'm hoping this is causing it as I just had the
disk on my new laptop replaced 6 months ago and I was afraid that it was
failing again.

Re: stable/12 git -> svn mirror delayed

[Warner Losh]

The problem is that it was a merge commit, which should have been
administratively prohibited. A merge commit from main to stable/* is never
the right thing. It creates problems, not least of which is the issue with
the subversion exporter. In this case, it won't create the more severe
issues like we have in the converted past, so that's at least something.

I wrote the script assuming there'd never be a merge commit. I'll fix
things by hand for this one commit which will get things going again.
Making this exporter handle merge commits generically is tricky and beyond
the scope of the work I took on...  Hopefully, we'll get the commit hook
problem fixed soon so it won't happen again.

stable/12 git -> svn mirror delayed

[Ed Maste]

The git-svn stable/12 mirror is currently stuck. It encountered an
issue with the OpenSSL 1.1.1j import (e3a8c0df593b) and hasn't been
able to make progress past it. It's under investigation and will
hopefully be resolved soon.

Dumb of me to show releng/12.0 instead of releng/12.2 , I guess.
But I luck out: releng/12.2 was only one day more recent . . .

Hi Mark,

    I track RELENG_12 stable (not 13) via svn still.  But I noticed on
the cgit page there are more commits to 12 STABLE then when I update via svn

If I try and update my sources via svn the last commit I get is

https://cgit.freebsd.org/src/commit/?h=stable/12=42f7f5c5d22cc9e845e51a1f8a5b92573b8b3d2f

# svnlite update
Updating '.':
At revision 369283.
#
#uname -a
FreeBSD backup.sentex.ca 12.2-STABLE FreeBSD 12.2-STABLE #0 r369282M:
Wed Feb 17 09:36:31 EST 2021
mdtan...@backup.sentex.ca:/usr/obj/usr/src/amd64.amd64/sys/server  amd64

On another RELENG12 machine if I do a git pull --ff-only I get what is
reflected at

https://cgit.freebsd.org/src/log/?h=stable/12

with several commits after the one by np ~ 43hrs ago

You are referencing 12, not 13 . . .

https://cgit.freebsd.org/src/log/?h=releng/12.0

shows the most recent releng/12.0 in git is from 2021-Jan-28:

Are you confusing stable/12 and releng/12.0 or 
possibly releng/12.0 and releng/13.0 ?

Hi Warner & Li-Wen,

    I think something might be broken somewhere ? The last update is
from ~ 36 hrs ago and there have been many commits to the git repo since
for RELENG_12.
