MIPS: assembly language query

Hi,

I m looking @ some MIPS kernel disassembly:

lui a0,0x8038

what address is the a0 at?

thanks,
Ashlesha.

a0 is not an address -- it's actually a register in the processor.

The instruction

lui a0, 0x8038

loads the hex number 0x8038 into the upper portion of register a0.

And by convention, it's the first argument to a function.
