Hi,
Does anyone know whether it is possible to read the ARM CCNT (cycle count)
register in SE mode? I can do the similar thing for X86 and alpha in SE mode,
but I get an error when I use the following assembly code to read CCNT:
asm volatile ("MRC p15, 0, %0, c9, c13, 0\t\n": "=r"(value));
panic: Attempted to execute unknown instruction.
Best regards
Fangfei
