Description Dave Cottlehuber freebsd_committer freebsd_triage 2025-09-01 11:29:09 UTC 
I get a crash every week or so, all open terminals die immediately.
can you bump the port please? there are updates to wgpu (the rusty
gpu interface library) and many others, and this alone might be
enough to address it.

wezterm version        : 20250213.133349_3
/usr/local/lib/libnvidia-eglcore.so was installed by package nvidia-driver-570.153.02.1500046

Running 15.0-CURRENT amd64 on NVIDIA gpu.

x11/wezterm: Update to 20250730-110715

Hello Dave,

Thank you for the report.
Just for the record: I don't experience the problem which you described (with NVIDIA GPU, wezterm-20250213.133349_5 and nvidia-driver-580.76.05.1500063).

I prepared and attached an update for wezterm port.
Now I'm going to test it for a few days.
Comment 2 Vladyslav Movchan 2025-09-03 15:00:16 UTC 
I submitted a patch to update wezterm port to the most recent version: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=289274
Comment 3 Vladyslav Movchan 2025-09-08 05:42:33 UTC 
(In reply to Dave Cottlehuber from comment #0)
Please try the latest port version.
Comment 4 Dave Cottlehuber freebsd_committer freebsd_triage 2025-10-10 12:13:23 UTC 
thanks! It looks like I got one already yesterday :-(, I'll wait and see if I get
another one & look at the core dump.
Comment 5 Dave Cottlehuber freebsd_committer freebsd_triage 2025-10-10 12:14:22 UTC 
currently running 15.0-ALPHA5, nvidia-driver-580.82.07.1500064, wezterm-20250730.110715_1
Comment 6 Mark Linimon freebsd_committer freebsd_triage 2025-10-11 04:57:19 UTC 
^Triage: in general we do not assign PRs to non-committers, on the basis that
they cannot actually do the commit.  In this case, the maintainer-feedback
mechanism is sufficient.
Comment 7 Mark Linimon freebsd_committer freebsd_triage 2025-10-27 20:01:14 UTC 
^Triage: to submitter: did the port update solve this problem?
Comment 8 Dave Cottlehuber freebsd_committer freebsd_triage 2025-11-17 00:07:10 UTC 
no, still seeing these crashes, on nvidia-drm-515-kmod-580.82.07.1500064_3 & wezterm-20250730.110715_1
Comment 9 Dave Cottlehuber freebsd_committer freebsd_triage 2025-11-17 09:41:54 UTC 
Got another one this morning, same spot:

(In reply to Dave Cottlehuber from comment #9)
I don't have an answer, but I spotted few bits which look like inconsistencies and might be related to the problem.

First is 1500068 vs 1500064 in versions of nvidia-kmod and nvidia-drm-515-kmod packages.
This number corresponds to __FreeBSD_version variable (from sys/param.h at the time of port/package compilation) and it represents kernel binary interface version.
Different values mean different KBIs which, in my understanding, might not be 100% compatible.

Second is 580.95.05 vs 580.82.07 in versions of most of the nvidia packages and nvidia-drm-515-kmod. I think this means nvidia-drm-515-kmod package has been built for/with older nvidia-driver sources.
Which, again, could have some incompatibilities.

Third: based on the contents of /usr/ports/graphics/nvidia-drm-kmod/Makefile recent FreeBSD 15 (with __FreeBSD_version >= 1500031) uses graphics/nvidia-drm-66-kmod package and not graphics/nvidia-drm-515-kmod.
I'm not sure how critical this 6.6 vs 5.15 difference is - maybe it is just "recommended".


Unfortunately, this is all I have for now.
