== notes ==
- uninative 2.3.2 with upstream fixes (might be issues with 2.3.3, please
have a look)
- swatbot has found some interesting things
== general ==
Randy: rebasing meta-rust into oe-core. it’s working, sdk needs work and
libsvg needs work
RP: have you seen the patches on the mailing list? (Jan-Simon, PaulB)
Randy: yes, haven’t looked at them yet
RP: do you know how they relate?
Randy: not yet, i’ll reply to the thread. is it needed for the next release?
RP: i’m not going to hold up the release for it, but it’d be nice
RP: there’s been a lot of churn in the versions (glibc, kernel, etc). if
anyone sees anything please raise a flag
Ross: yes, I’ve seen some issues, not always 100% reproducible
RP: x86 host?
Ross: not always
TimO: ubuntu host?
Ross: 20.04
RP: glibc-2.33 does have some interesting things, so i’m not surprised there
are issues
Randy: what are you seeing?
Ross: issues building the kernel (“dangerous relocations”)
RP: for dunfell we did a glibc-2.32 update but we’ll hold off on glibc-2.33
(thanks Michael!)
Ross: turning off uninative makes it go away
TimO: is that a Xen kernel?
Ross: no, just defconfig
TimO: (for Bruce) interested in kubernetes or k3s
Bruce: i upgraded pretty much everything in meta-virt over the weekend, k3s is
broken but everything else is good
TimO: how was FOSDEM?
Bruce: best platform so far, better than ELC/E
TimO: their own, or same as Plumbers?
ScottM: their own, something with matrix and jitsi
Bruce: not a lot of OE stuff, specifically, but mentioned in a bunch
(embedded, license, distros, virtualization)
JPEW: was going to give a talk at ELC, (virtual, labgrid, etc)
TrevorG + TimO: we should talk
TrevorG: we’ve got interesting things working, so we were going to give a
talk (kube-virt tekton stuff)
ScottM: for AGL there’s a project to do drm stuff on the host (wayland) from
within a virt machine (virgl)
Randy: is x11 really dead?
Ross: yes, no upstream maintainer
JPEW: i’ve been looking for a good Weston compositor that would be a good
replacement for Sato. even if it just listed out the .desktop files that
could be clicked
Ross: there are some
JPEW: but they’re not great on a 5” screen. there is the IVI shell, but
any apps have to use the IVI shell extensions
ScottM: AGL just migrated away from it. i’ll have to look it up, but there
is a compositor that uses libweston
Ross: i looked at matchbox to see if the sato bits could be converted to
weston. it should be possible, the hooks are there, but i haven’t gone
any further
TimO: the problems with the compositors that i looked at needed QT
JPEW: sway is a good tiling compositor, but we need something that would be
good for an embedded demo
ScottM: maynard is the one from colabora, it was dead, but i think it’s
going to be picked up again. another one would be to use wlroots or
libweston to piece something together
TimO: libweston would be a good one
ScottM: the AGL one targets libweston, libweston had updates to support this
use-case
TimO: also need to consider testability, worked with dogtail but it was
“hacky”
Ross: gtk4 has a re-written accessibility module
RP: there is a layer that RedHat has been working on called meta-rpm,
they’ve been making noises about automotive stuff. it’s completely
beta software so far, native only, they’re repackaging their binaries to
look like yocto packages
TimO: it looks like something similar to what Siemens is doing (isar)
RP: they’re looking at re-writing pseudo
ScottM: is that public?
J-S: it’s on a gitlab: https://gitlab.com/fedora-iot/meta-rpm
JPEW: the idea is “you can run Fedora and put stuff from your own layers on
top”
J-S: it works for a test build they’re doing, it’s actually CentOS8
ScottM: it would be interesting for commercial folks if it was RHEL
JPEW: the idea is “i have this recipe from OE that i want to run on CentOS”
RP: my fear is RedHat is pretty large
Alejandro: my fear is that all distros might take up this path
RP: from a public perception point of view we need to make sure people realize
this isn’t how Yocto is supposed to be done
Randy: the repo started in Nov 2020, the 90% developer on the project seems
like someone we’re linked to (LinkedIn)
RP: both Ross and I have reached out the project
Alejandro: our DNF is quite old, is that good or bad?
RP: don’t think it matters, they’re using DNF in native mode to run
the post-installs which runs into problems with pseudo (we don’t use
chroot). it has a lot of constraints (like isar)
Randy: we’re on the DNF from Dec 2020, and the latest was just released 12
days ago, so we’re not that far behind
TimO: AlexK did quite a lot of work on updates recently, and DNF was not one
of the easy ones
JPEW: (for Michael) any updates on the reproducibility page?
MH: i haven’t had a look at it yet
JPEW: I was hoping it would be hosted on the YP page, is that what you were
thinking?
MH: i thought we were pulling from your site (the JSON) and we’d pull from
there
JPEW: i was putting it up so you could see the HTML, but i wanted it to be
hosted on the YP page, it doesn’t work on mine due to x-site-scripting
checks in browser, so it needs to all be hosted on the same site. if
x-site-scripting is turned off in browser it works, but we can’t expect
that
TimO: i was trying to share the 3.3 release schedule with an intern but we
don’t have one
SJ: probably my fault
RP: as part of the automation there were questions about what we needed and
what was not being used
TrevorW: ELC has been cancelled, should we do something? especially the
training (devday)
RP: need to bring it up with the people who would normally organize it
