It seems to work here, I tried with this program but I haven't checked if t= he returned value are sane: #include <stdlib.h> #include <stdio.h> #include <sys/types.h> #include <machine/armreg.h> #include <machine/_stdint.h> int main(int argc, char **argv) { uint64_t id_aa64isar0, id_aa64pfr0; id_aa64isar0 =3D READ_SPECIALREG(id_aa64isar0_EL1); id_aa64pfr0 =3D READ_SPECIALREG(id_aa64pfr0_EL1); printf("id_aa64isar0: 0x%lx, id_aa64pfr0: 0x%lx\n", id_aa64isar0, id_aa64pfr0); return (0); } ./identcpu id_aa64isar0: 0x111110012120, id_aa64pfr0: 0x110000 I haven't tried qemu-user-static. --=20 You are receiving this mail because: You are the assignee for the bug.=
