It's not entirely clear to me what information people need or want, and there's some data in /proc/cpuinfo that I think makes no sense to try to export export in a structured way (e.g. bogomips). > > Tested on aarch64: > > /sys/devices/system/cpu/cpu1/info/:[0]# ls > architecture bogomips flags implementer part revision variant > > ------------------------------------------------------------ > > for file in *;do echo $file; cat $file;echo;done > architecture > 8 > > bogomips > 40.00 > > flags > fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid asimdrdm > > implementer > 0x51 > > part > 0xc00 > > revision > 1 > > variant > 0x0 For arm64 we already expose the MIDR and REVIDR register values under /sys/devices/system/cpu/cpu*/regs/identification, and that's the bulk of the useful information above (aside from the flags/hwcaps).
