/arch/um/drivers/chan_kern.c:
...
int generic_read(int fd, char *c_out, void *unused)
{
int n;
n = os_read_file(fd, c_out, sizeof(*c_out));
if(n == -EAGAIN)
return(0);
else if(n == 0)
return(-EIO);
// I will intercept the call here in UML.
// I hope it's ok.
printk("<1>generic_read\n");
return(n);
}
For non-uml interception, i guess I could try
with drivers/char/keyboard.c
static void kbd_keycode(unsigned int keycode, int down,
int hw_raw, struct pt_regs *regs)
{...}
Well. Trying with UML first.
Thanks a lot.
