Rich Ercolani	1d84c9eb66	Fix /proc/spl/kstat/simd on x86 ... Evidently while reworking it on aarch64, I broke it on x86 and didn't notice. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Rich Ercolani <rincebrain@gmail.com> Closes #16556	2024-09-22 13:11:19 -07:00
Rich Ercolani	5d01243964	Add SIMD metadata in /proc on Linux ... Too many times, people's performance problems have amounted to "somehow your SIMD support isn't working", and determining that at runtime is difficult to describe to people. This adds a /proc/spl/kstat/zfs/simd node, which exposes metadata about which instructions ZFS thinks it can use, on AArch64 and x86_64 Linux, to make investigating things like this much easier.
