Update to vmlinux-v6.10-rc2-g1edab907b57d.h Sync to vmlinux.h from sched_ext/for-6.11 1edab907b57d ("sched_ext/scx_qmap: Pick idle CPU for direct dispatch on !wakeup enqueues"). This most likely will be the commit which will be merged during the upcoming kernel v6.11 merge window. Unfortunately, this is a compatibility breaking change. As the size of bpf_iter_scx_dsq is reduced, schedulers that use the iterator - scx_lavd and scx_layered - won't be able to run on older kernels. Likewise, older binaries from before this commit won't be able to run on newer kernels. 2024-07-12 21:35:14 +01:00			`# scx_flatcg and scx_pair are temporarily excluded until cgroup support`

scx: Add CI action that builds schedulers for PRs When Ubuntu ships with sched_ext, we can also maybe test loading the schedulers (not sure if the runners can run as root though). For now, we should at least have a CI job that lets us verify that the schedulers can _build_. To that end, this patch adds a basic CI action that builds the schedulers. As is, this is a bit brittle in that we're having to manually download and install a few dependencies. I don't see a better way for now without hosting our own runners with our own containers, but that's a bigger investment. For now, hopefully this will get us _some_ coverage.

build: introduce kernel_headers build option If we try to cross-build scx on builders with older versions of system's linux headers (such as those provided by linux-libc-headers in older releases of Ubuntu), we may hit build failures, due to the different kernel ABI, such as: error: invalid use of undefined type ‘struct btf_enum64’ To address this, introduce a new build option called "kernel_headers" that allows to specify a custom path for the kernel headers required during the build process.
