ioperm problem
Hi,
I''m trying to port AMD VGA passthru patch to the latest XEN and vanila kernel
and I got SIGSEGV in
static void ati_hw_out(uint16_t hport, uint32_t data)
{
ioperm(gfx_info.host_pio_base, gfx_info.pio_size, 1);
asm volatile ("out %1, %0"::"Nd"(hport),"a"(data));
ioperm(gfx_info.host_pio_base, gfx_info.pio_size, 0);
}
I tried old 2.6.32
