RP: it’s hard to programmatically determine what is an override and what isn’t. an underscore is an accepted symbol in many areas and is also an override qualifier. i have a whole bunch of stuff working, but it’s hard to find things that aren’t found/converted by the script. i hope layers will be converted quickly (layers outside of core) TrevorW: what’s the script name and where do we find it? RP: in master-next scripts/contrib/convert-overrides.py. i’ve put comments in to help, there are some changes that are needed (e.g. removing hard-coded paths). also ARCH overrides are particularly hard to do, so i’ve mostly done them by hand PaulB: will the new syntax be backported to dunfell and hardknott? RP: dunfell onwards : good! Armin: layers need to be fixed up in dunfell RP: only if you’re trying to make your dunfell branch work with master PaulB: what happens if you mix and match RP: it will error out and not parse, the colon was not a legal character previously so it will fail PaulB: noisy errors are the best RP: m2 now in QA. there is an issue with systemtap not working on Intel. no details from the QA team to figure out what went wrong. also there is a runtime issue on beaglebone-yocto to do with the keyboard. there’s a backlog building up for QA (3.3.2 and 3.1.10). we’re a bit down on AB power ScottM: are there bugzilla entries for those two? RP: yes. odd that the systemtap issue didn’t pop up on the AB PaulB: it looks like a 64 vs 32 bit issue. the register names indicate 64-bit but it’s pulling in a 32-bit header? RP: hmm. that looks like that’s the case ScottM: there should be a new rev of prserv patch later today PaulB: mixin layers. is that the way to go or do we want 1 layer? RP: i prefer mixins, then we can distribute maintainership more easily. adding mixin layers can get messy, which is good since i’d rather have users have to think about what they’re mixing in  PaulB: if the mixins are orthnogonal then they should work easily together RP: yes, if they’re orthogonal, but how do you ensure that? TimO: any news on a next yocto conference/devday? TrevorW: plans are in the works PaulB: is there a place with a list of YP-related talks at elc? TrevorW: not that i know of PaulB: i’ll put the list together on the wiki and post to irc https://wiki.yoctoproject.org/wiki/Embedded_Linux_Conference_2021 RP: and mailing list too please TimO: some of us have started posting our links to irc RP: JPEW will be giving a presentation at an LF security supply-chain event. this will be good to help advocacy  https://events.linuxfoundation.org/supply-chain-town-hall/ JPEW: i’ll be discussing reproducible builds and sw build materials (aug 18) RP: it would be nice if you could add cve tracking too JPEW: SS can help RP: we have pretty graphs TrevorW: the advocacy people have been wondering if YP should advertise at Embedded World ScottM: ask J-SM i think he has attended (as a part of the AGL) MO: and/or we could give YP-related talks
