Hello,
I would like to know, where exactly NIC interrupt starts/ends. Underneath
there is part of (2.4.20) 8139too.c code that handles interrupts rx/tx.
I don't know if:
line numbers 2044/2098 (spin_lock()/spin_unlock) are the interrupt
start/end boundaries
... or let say in rx case only:
line 2073 (rx_interrupt())
*******************************
* 8139too.c: rtl8139_interrupt(), code snippet
*
*******************************
2032 /* The interrupt handler does all of the Rx thread work and cleans up
2033 after the Tx thread. */
2034 static void rtl8139_interrupt (int irq, void *dev_instance,
2035 struct pt_regs *regs)
2036 {
...
2043
2044 spin_lock (&tp->lock);
2045
2046 do {
...
2073 rtl8139_rx_interrupt (dev, tp, ioaddr);
..
2082 rtl8139_tx_interrupt (dev, tp, ioaddr);
...
2087 boguscnt--;
2088 } while (boguscnt > 0);
...
2098 spin_unlock (&tp->lock);
thanks for any help in advance
regards
adam
