Something like this? (Warning, will not probably even compile on
x86-64, I do not have 64-bit compiler near me).
static inline void native_io_delay(void)
{
- asm volatile("outb %%al,$0x80" : : : "memory");
+ udelay(8);
}
Alan, did you double-check that 8 us? I tried to but I seem to not have
trustworthy documentation.
