Subject: [PATCH 2/4] sched_ext: Sync tools autogen enum lookup tables from the scx repo
Date: Fri, 23 Oct 2026 13:21:00 -1000	[thread overview]
Message-ID: <20261023232102.1124938-3-tj@kernel.org> (raw)
In-Reply-To: <20261023232102.1124938-1-tj@kernel.org>

Sync the two enum lookup tables, enums.autogen.h and enums.autogen.bpf.h,
with the scx repo at a094b6ec68c9 ("scheds/include: Sync with kernel
sched_ext/for-7.5 (b1c2a6b0d90d)").

The kernel copy gains SCX_ENQ_CPU_SELECTED, which scx added in f2fd24198edc
("scheds/include: Add SCX_ENQ_CPU_SELECTED to the enum tables"). The flag's
value changed in 376f8963bbda ("sched: Re-arrange the {EN,DE}QUEUE flags"),
so BPF code should read it from the running kernel.

ebf993609d70 ("sched_ext: Regenerate tools autogen enum headers")
regenerated the other two tables, enum_defs.autogen.h and
enums_abi.autogen.h, from this tree's vmlinux.h. They are newer than scx's
copies and stay as they are.
