Rpi 3B+ Linux kernel 6.12 can be compile with CONFIG_SCHED_CLASS_EXT and eBPF?

[ziyangfu]

Linux kernel 6.12 introduced an important feature, sched_ext, which can implement user-space schedulers with the help of eBPF.
I see that the Raspberry Pi OS kernel has already been upgraded to 6.12. Therefore, I want to test it on Raspberry Pi 3B+. However, the pre-built kernel in defconfig doesn't have this configuration enabled.
Can I manually build a kernel with SCHED_EXT? Has anyone tried this, and what potential issues might I encounter?

We don't normally allow questions here, but this might be of interest to others.

There are instructions for building your own kernels here: https://www.raspberrypi.com/documentation/computers/linux_kernel.html#building

Perhaps somebody else has tried SCHED_EXT - I haven't.
