cdi 492c11116f Revert previous change as it breaks the build on a number of ports. 2003-10-18 21:26:22 +00:00
cdi 2b3e81f067 Introduce null console. This pseudo device acts as a normal console with the 
exception that it discards any output, and is useful for booting the kernel
on headless boxes.

dsl 23069255ce Make 'minor(dev) == 1' a device that isn't affected by TIOCCONS. 
For /dev/constty so that you can grab kernel messages when logged in
on the 'console'.

agc aad01611e7 Move UCB-licensed code from 4-clause to 3-clause licence. 
Patches provided by Joel Baker in PR 22364, verified by myself.

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.
 2003-06-29 22:28:00 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
 2003-06-28 14:20:43 +00:00
matt 7109fe9012 Add cn_halt and cn_flush entries to consdevs. (needed for dma-only console 
devices).

jdolecek e0cc03a09b merge kqueue branch into -current 
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

provos 0f09ed48a5 remove trailing \n in panic(). approved perry. 2002-09-27 15:35:29 +00:00
gehenna 77a6b82b27 Merge the gehenna-devsw branch into the trunk. 
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

soren 5fa952b83f As in PR kern/10999 from Matthew Orgass, make the panic message more 
helpful in the case where no console device has registered.

jdolecek 07677cc805 Use back the 'u'&037 form - since it's CTRL-u, it's more readable that way 
Use \007 instead of symbolic constant, since that's what is more often used.
Pointed out by Robert Elz.

mrg 305e44c869 check for when cnopen() will call itself recursively, and panic instead of losing badly. 2000-06-12 05:02:22 +00:00
itojun e6469f14ad move static function getstr() to cons.c, make it publically available 
as cngetsn().  there will be other consumer.

thorpej a183d34f04 - Implement cnbell() -- ring the console bell. The cn_bell entrypoint 
is optional.
- Add cn_bell to statically allocated consdevs as appropriate.
