* We don't need to call dcons_poll event handlers if KDB is not active.Hidetoshi Shimokawa2007-08-171-3/+9
| | | | | | | Approved by: re (kensmith) Notes: svn path=/head/; revision=171867
* - Don't force to be the GDB port since dcons(4) is in GENERIC now.Hidetoshi Shimokawa2007-06-111-1/+5
| | | | | | | | | To enable the GDB port of dcons(4), you need to put dcons_gdb=1 in /boot/loader.conf. Notes: svn path=/head/; revision=170537

* Add the address of IDT in the configuration ROM. (i386/amd64 only)Hidetoshi Shimokawa2007-06-082-0/+27
| | | | | | | | | | | | | | | A change to dconschat(8) will follow so that it can bomb this address over FireWire to reset a wedged system. Though this method is just a hack and far from perfection, it should be useful if you don't want to go machine room just to reset or to power-cycle a machine without remote-managed power supply. And much better than doing: # fwcontrol -m target-eui64 # dd if=/dev/zero of=/dev/fwmem0.2 bs=1m Notes: svn path=/head/; revision=170420

* Poll bus resets on FireWire while kdb/gdb is active.Hidetoshi Shimokawa2007-06-083-0/+19
| | | | | | | | | | | | | | | | | | 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) Notes: svn path=/head/; revision=170408

* Add new function ttyinitmode() which sets our systemwide defaultPoul-Henning Kamp2004-10-181-6/+1
| | | | | | | | | | | | | | | | | modes on a tty structure. Both the ".init" and the current settings are initialized allowing the function to be used both at attach and open time. The function takes an argument to decide if echoing should be enabled. Echoing should not be enabled for regular physical serial ports unless they are consoles, in which case they should be configured by ttyconsolemode() instead. Use the new function throughout.

| | | | | | | | | | | | | | | o Use kdb_alt_break() to handle the alternate break sequence instead of handcoding it here. o Remove GDB kluges to make this driver work with the pre-KDB remote GDB code. o Call kdb_enter() instead of Debugger(). Note that with this commit the dcons(4) driver cannot be used for remote debugging anymore. This driver has to use the new GDB debug port interface instead. Such has not been done yet.
