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
