Program received signal SIGILL, Illegal instruction. 0x0000005555555720 in opal_sys_timer_freq ()
MRS Move the contents of the CPSR or SPSR to a general-purpose register.
Usage Use MRS in combination with MSR as part of a read-modify-write sequence for updating a PSR, for example to change processor mode, or to clear the Q flag.
Caution You must not attempt to access the SPSR when the processor is in User or System mode. This is your responsibility. The assembler cannot warn you about this as it does not know what processor mode code will be executed in.
Architectures This instruction is available in ARM architecture versions 3 and above.
걍 armbian 하니 잘 된다. 커널 버전이나 aarch64 지원이 미흡한 구버전 커널이라 그럴수도 있을 듯 하다.
