Hi,
there is still a little problem with ne2000:
(1) when the vm is in stopped state packets are still received
(2) this can fill the receive buffer before savevm ...
(3) when restarting qemu with loadvm the buffer is still full
(4) the guest OS does not get an int, so it does not know that
data is in the buffer
(5) new data will be discarded (buffer full) - the guest OS
waits forever.
(6) this make windows (users) unhappy.
One possible solution (but not a perfect one) is to block
receiving when the vm is stopped:
8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---
static void ne2000_receive(void *opaque, const uint8_t *buf, int size)
{
// ... some lines skipped
if (s->cmd & E8390_STOP || ne2000_buffer_full(s) || vm_running == 0)
return;
// ... some lines skipped
}
