Greetings,
One of my developers are getting spurius ^[[G outputs from keyboard driver. Im
100% certain that its caused by keyboard
driver and removing report_key also removes the problem.
I extracted some numbers when it happens and they show some linear structure,
but so far failed to understand
why it doesn't work.
It happens when j = 5, i = even number (2, 4, 6, 8, 10)
Here are the values this developer is getting at boot (along with 5 x ^[[G)
(j , i, scancode, xor, bit)
5, 6, 53, 32 , 32
5, 8, 69, 32 , 32
5, 4, 37, 32 , 32
5, 2, 21, 32 , 32
for (i = 0; i < JORNADA_SCAN_SIZE; i++) {
unsigned char new = jornadakbd->new_scan[i];
unsigned char old = jornadakbd->old_scan[i];
unsigned int xor = new ^ old;
/* no difference, then skip */
if (xor == 0)
continue;
/* run through bits and compair */
for (j = 0; j < 8; j++) {
unsigned char bit = 1 << j;
if (xor & bit) {
scancode = (i << 3) + j;
if(j == 5)
printk(KERN_INFO "kbd: reporting i=%d,
j=%d, code=%d, xor=%d, bit=%d\n", i, j, scancode, xor, bit);
input_event(input_dev,
EV_MSC, MSC_SCAN, scancode);
input_report_key(input_dev,
keymap[scancode],
!(new & bit));
sync_me = 1;
}
}
}
if (sync_me)
input_sync(input_dev);
}
