| H A D | dcons_os.h | diff 170408 Fri Jun 08 00:54:44 MDT 2007 simokawa Poll bus resets on FireWire while kdb/gdb is active. Now, it's safe to call the fwohci interrupt(polling) routine while ddb/gdb is active. After this change, a dcons connnection over FireWire can survive bus resets even in kernel debugger. This means that it is not too late to plug a FireWire cable after a panic to investigate the problem. Actually there is a small window(between a jump to kernel from loader and initialization of dcons_crom) in which no one can take care of a bus reset. Except that window, firewire console should keep working from loader to reboot even with a panic and a bus reset. (as far as you enable LOADER_FIREWIRE_SUPPORT) |
