You can get the PC from the debug register. However, this stuff is asynchronous wrt to the firmware. So the PC would have absolutely no meaning. The interrupt takes a few microseconds to trigger and the bottom half probably takes up to a few milliseconds. So the firmware will have advanced a lot until you dump the state. For this reason I introduced the synchronous debug-irq. With this IRQ it's possible to synchronously send events to the driver and dump some state in a consistent way. However, it requires firmware support, of course. We cannot read the conditions without help of the firmware. Or at least, we don't know how to, if it's possible somehow. -- Greetings, Michael. _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
