512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

3f99f14bf1 OK, I messed up /dev/console with what I had hoped would be compat
code.  Convert remaining console drivers and hope for the best.

945ff31afa Use __FBSDID().
Also some minor style cleanups.

d42ee4e410 Note that MAJOR_AUTO is now the default if d_maj is not initialized. This
is more robust and prevents the hijacking of /dev/console for the typical
mistake.

Remove unneeded MAJOR_AUTO uses, it is only needed explicitly now if the
driver source has cross-branch compatibility to old releases.

182a9f7455 Make nokqfilter() return the correct return value.
Ditch the D_KQFILTER flag which was used to prevent calling NULL pointers.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

3fb37429df Use MAJOR_AUTO. GC statically assigned majors. 2003-02-28 04:21:13 +00:00

263444cfbf Change the console interface to pass a "struct consdev *" instead of a
dev_t to the method functions.

The dev_t can still be found at struct consdev *->cn_dev.

Add a void *cn_arg element to struct consdev which the drivers can use
for retrieving their softc.

a68a96aad7 Add the sabtty children devices as unordered. Use the unit numbr of
the sabtty device to create its description so that they will be
unique for machines with multiple sab chips.

This fixes a panic on machines with an rsc card.

a720ae1bbe Sync with zs.
- Fix some bogosity with mixing unit numbers and channels, which would only
  work for one instance of the device.
- Use a simpler scheme for input and output queueing.
- Use db_alt_break.

e2815d20d9 Setup a default tty mode even if the device is not the console. Don't
reset the chip on open if we're not the console.

This fixes running a getty on ttya or ttyb if console input and output
devices are screen.

4ce7e0f43a Remove some unnecessary code. Make the device description nicer. Add a
delay in the right place to flush output before switching consoles.

810c82e6c2 - Add support for ALT_BREAK_TO_DEBUGGER; this is the only reliable way to
trigger a breakpoint with this chip.
- Fiddle the right bits in the cn input and output routines to disable port
  interrupts and enable visibility of the masked interrupt status bits.
- Register a shutdown final event handler to put the chip back in the mode
  that the prom expects.

c0d676c068 Make this driver work a whole lot better.
- Get the initial mode from the prom settings and don't clobber the mode
  on open.
- Copy output into an internal ring buffer instead of accessing the tty
  outq directly in the interrupt handler.  This fixes a problem where
  garbage would show up in the output stream.
- Reset the console port completely and reprogram all the parameters
  before enabling it.  This fixes seemingly random hangs on startup
  when using a fast interrupt handler.
- Add minimal locking in place of spls.
- Remove dead code and minor cleanups.
