Hi all,
As the discussion was going on about the effects of trapping the
netpoll queue during KGDBoE debugging, I tried avoiding it. So in
eth_pre_exception_handler() I did not set net_poll_trap to 1 and did not
reset it back to 0 in eth_post_exception_handler()
file drivers/net/kgdboe.c
static void eth_pre_exception_handler(void)
{
/* Increment the module count when the debugger is active */
if (!kgdb_connected)
try_module_get(THIS_MODULE);
// netpoll_set_trap(1);
}
static void eth_post_exception_handler(void)
{
/* decrement the module count when the debugger detaches */
if (!kgdb_connected)
module_put(THIS_MODULE);
// netpoll_set_trap(0);
}
As i started testing KGDBoe, 1st time I did
(gdb)info threads
and it worked, but after that I set breakpoint
(gdb)break link_path_walk
after this any of the commands were not working and the test machine
went in hang state.
To provide more information, I am working on an i386/x86_64 Athlon box,
using 2.6.17 kernel and 100Mbps, full-duplex, VIA Rhine network card.
