# SIG/Kernel meeting 2023-11-30
## Attendees
* Sherif Nagy
* Neil Hanlon
* Pratham Patel
* Mustafa Gezen
* Pablo Greco
## Discussions
* This SIG does have some overlap with SIG/Altarch
* Altarch was expecting to base on elrepo
* Two options: mainline and LTS. Default to Mainline
* Two kernels right now:
* LTS - manual, done by Pablo
* Mainline - kernel packer in Peridotv2
* standard config from upstream doesn't support a lot of our SBCs
* intending to stay as close to upstream as possible
* Upstream == fedora rawhide branch's RHEL configs
* ** Can we build a kernel-mainline artifact for altarch. e.g., kernel-mainline-sbc like kernel-rt/64ka **
* Alternatively, we can create a new package for that name, but that is probably a lot of rework (?)
* ELrepo contributions
* What changes are we going to contribute?
* There are some subset of changes which are beneficial to the overall ecosystem (like an SBC variant which is disabled by default)
* There's some stuff they might not want to use, and our specs will definitely change over time, not necessarily in step with ELRepo
* Mainline variant for SBCs
* Two options: subpackage of mainline or discrete packed kernel with a new name
* Leaning towards a discrete package which can be 'packed' directly into git.r.o/sig/altarch/ namespace, if needed
* Idea on generating kernel configs for SBCs
* For some sbcs we need to boot via dtb and not acpi so we require mainline kernel
* usually require drivers which are disabled by default
* https://git.resf.org/thefossguy/kernel-elrepo/commit/ff349cb79376d1ef4b80c4f8c2cb07703dc3db5e
* Pablo: Fedora is generally open to enabling these in those configs, and are usually enabled already
* RHEL configs are a lot more conservative as they only enable what they need
* Harder to go from RHEL -> working SBC than Fedora -> working (typically), so this is the approach usually he takes
* ELRepo is in the middle :)
* Recommends starting with fedora than trying to work backwards
* Pratham will try this
* Also working on comparing 9.2 configs to 9.3 with prior work on sbc enablement
* seems to be working (booting) where elrepo kernel was not
* need to work out when acpi is not there
* https://gitlab.com/cki-project/kernel-ark
* Mainline kernel is 6.5 right now, we will go to 6.6
* There is an issue with 6.7, we have issues w/ NX and shim
* There is an exception for Linux distributions right now, but we won't be able to sign 6.7 without a new shim
* We'll try and hold onto 6.6 for as long as we can -- and that's OK
* May need to have non-nx and nx-ready shim
* :upside-down-face:
* Sherif will be working on LTS 6.1 on x86 a bit this week
