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
- What changes are we going to contribute?
- 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
ff349cb793- 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
- For some sbcs we need to boot via dtb and not acpi so we require mainline kernel
- 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
