Is there a tilme stamp register on R5900 processor ?

I have tried the classical mips instruction:

__asm__ __volatile__("mfc0 %0,$9; nop" : "=r" (dest))

but I get only an illgal instruction.

I dont have the Instruction set manual. Can someone help me ?

There are other threads that mention the asm to read the time stamp, but you may be interested on the EE's performance counters:
