* Remove local hacks to set flags now that the device probe does this for us.Nate Lawson2004-10-141-4/+0
| | | | | | | | | | Tested on every device except sio_pci and the pc98 fd.c. Perhaps something similar should be done for the "disabled" hints also. MFC after: 2 weeks Notes: svn path=/head/; revision=136520
* Use generic tty code instead of local stuff.Poul-Henning Kamp2004-10-131-521/+79
| | | | | | | NB: device names are now consistent: {cua,tty}d$(port)[.lock,.init] Notes: svn path=/head/; revision=136478

* Allocate tty at attach time rather than open time.Poul-Henning Kamp2004-09-161-49/+43
| | | | | | | | | | | Use the init/lock*in/out fields in struct tty and remove them from our softc. Use tty->t_sc to find out softc when convenient. Mostly OK'ed by: bde Notes: svn path=/head/; revision=135329
* If you insert a pccard modem and then eject it, you get a panic. ThisWarner Losh2004-07-221-1/+2
| | | | | | | | | | happens because the sio device was never opened and com->tp is therefore NULL. ttygone can't swallow a NULL, so guard against that possibility. Other places in this function make similar checks, so I believe this is correct. Notes: svn path=/head/; revision=132561
* Preparation commit for the tty cleanups that will follow in the nearPoul-Henning Kamp2004-07-151-2/+2
| | | | | | | | | | | | future: rename ttyopen() -> tty_open() and ttyclose() -> tty_close(). We need the ttyopen() and ttyclose() for the new generic cdevsw functions for tty devices in order to have consistent naming. Notes: svn path=/head/; revision=132226

* Update for the KDB framework. Sanitize the alpha console code now thatMarcel Moolenaar2004-07-101-209/+76
| | | | | | | | | | | | | | | | | | | | | it's in the way even more. Basicly: remove all alpha specific console support from gfb(4), sio(4) and syscons(4). Rewrite the alpha console initialization to be identical to all other platforms. In a nutshell: call cninit(). The platform specific code now only sets or clears RB_SERIAL and thus automaticly causes the right console to be selected. sio.c: o Replace the remote GDB hacks and use the GDB debug port interface instead. o Make debugging code conditional upon KDB instead of DDB. o Call kdb_alt_break() instead of db_alt_break(). o Call kdb_enter() instead of breakpoint(). o Remove the ugly compatibility of using the console as the debug port.

* Pick the hotchar out of the tty structure instead of caching privatePoul-Henning Kamp2004-06-261-6/+5
| | | | | | | | | | | copies. No current line disciplines have a dynamically changing hotchar, and expecting to receive anything sensible during a change in ldisc is insane so no locking of the hotchar field is necessary. Notes: svn path=/head/; revision=131134

* Remove new options and my prevention of system freeze when the sio probeDoug Ambrisko2004-05-031-76/+49

* Some enhancements and bug fix.Doug Ambrisko2004-04-301-49/+76
| | | | | | | | | | | | | | | | | | | | | - Define option FORCECONSPEED to force the serial console to be CONSPEED. I've run into a lot of boards in which the detect for prior speed doesn't work and ends up with broken console since it is at the wrong speed. - If a serial port is marked as a console, but console=vidconsole and if the serial ports doesn't exist it will be probed and attached at a 8250 chip. Then writes to that will freeze the system. - Add an option flags 0x400000 to mark this as a potential comconsole in-case the one flaged with 0x10 does not exist in the system. This makes it easier to deploy on systems with one or two serial ports. Obtained from: IronPort Notes: svn path=/head/; revision=128781

| | | | | | | | | | | Introduce d_version field in struct cdevsw, this must always be initialized to D_VERSION. Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing four D_NOGIANT flags and adding 145 D_NEEDGIANT flags. Notes: svn path=/head/; revision=126080

* Tweaked the siointr1() so that it works better at 921600 bps, especiallyBruce Evans2003-11-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | with multiple ports on a shared interrupt demultiplexed by the puc_intr() handler. siointr1() first read as much input as possible and then checked all possibly-relevant status registers, partly for robustness and partly for historical reasons. This is very bad if it is called for every port sharing an interrupt like puc_intr() does. It can spend too long reading all the input for some ports when the interrupt is for a more urgent event on another, or just too long checking all the status registers when there are lots of ports. The inter-character time is too long for reading all the input even when the interrupt is for a transmitter interrupt on the same port, and at 921600 bps the inter-char time is 10.85 usec and was often exceeded with just 2 ports, leaving the transmitters idle for about 6% of the time. The tweak is to break out of the read loop after reading 1 char if output can be done. This avoids most of the idle transmitter time for 2 active ports at 921600 bps bidirectional on the test system. It also reduces overhead by about 20%. More complete fixes use the programmable tx low watermark on 16950's and reduce overhead by another 65%. Notes: svn path=/head/; revision=122844
* Don't waste so much space for the latency debugging buffer. Its sizeBruce Evans2003-11-161-10/+8
| | | | | | | | | | | | | | | will now need editing except for spot checks. Changed this buffer from a circular one to a linear one. This is more useful for some cases and the sysctl that prints it doesn't support circular buffers. Fixed (output) formatting bugs in this sysctl. An off by 1 error caused a garbage byte to be returned after annotation of large deltas, and a race with the writer sometimes caused premature string termination.
