Hi All:
I want to move two local valuables to x86 arch CPU ebx, ecx
register and do outb cpu instruction by using AT&A inline asm in
kernel driver. The following code was I wrote but gcc report syntax
error:
==
unsigned int val = 10;
unsigned int tmp = 5;
....
__asm__ volatile ("movl %0, %%ebx"
"movl %1, %%ecx"
"outb $0x27, $0xb2"
:
:"r"(val), "r"(tmp)
:"%ebx", "%ecx"
);
Does anyone can point me out. Any reply is appreciated.
BRs, H. Johnny
