* Cleanup serial console handling and remove some of the MD code from com.c.jsing2008-04-241-27/+9
| | | | | | | | | | Specify the serial configuration from within the MD code, rather than passing things via macros. This will allow other platforms to more readily change the serial console configuration. Committing this so it actually gets tested. ok dlg@
* Increase buffer size sent to the fifo, and clamp the size correctly.deraadt2008-04-091-5/+6
| | | | Scrub the buffer afterwards, too
* Cleanup cn_pri. Change constants to more meaningful names, rather thanjsing2008-01-231-4/+4

| | | | | | | | | have to force all console devices to. this change passes the right speed to the com code, and continues to use it when the device is opened as the console device. figured out by kettenis@ ok kettenis@ miod@

* Delay switching to the real serial console until we attach the serial device.kettenis2007-07-151-7/+1
| | | | | | | | The variety of different serial devices is just too big to make a decision up front. This should make the second serial port on four-digit B/C/J-class workstation work as a serial console too. ok miod@

* Let cons_init() and cons_init_bell() initialize the whole consdev structure,miod2006-01-011-10/+4
| | | | | thus removing the need for drivers to initialize cn_pri to CN_DEAD when hardware probe fails.
* Move contents of sys/select.h to sys/selinfo.h in preparation for amillert2005-11-211-2/+2
| | | | | userland-visible sys/select.h. Consistent with what Net and Free do. OK deraadt@, tested with full ports build by naddy@.

* Enable IR receive mode only for infrared capable PXA2x0 UARTs. Normaluwe2005-07-111-7/+14
| | | | | | | | | reception is blocked while the IR receiver or transmitter is enabled. Also enable the PXA2x0 UART before clearing the FIFO (suggested by drahn@ some time ago), and disable the UART in compwroff(). ok deraadt@

* - Merge changes from pxacom back into the common com driver.uwe2005-05-271-17/+144
| | | | | | | | | Changes to the common com driver (partly from NetBSD): - Multiply before divide in comspeed() to avoid overflow (from NetBSD). - Don't call getc() and send -1 if the output queue is empty. - Take UART clock frequency as a parameter instead of using COM_FREQ. ok deraadt@

| | | | | | | | | separate tty registering is gone now that sparc has switched to wscons, and this makes the code less error-prone. Also, remove tests for ttymalloc() failure, since it uses M_WAITOK. ok millert@ deraadt@, tested by various people as well besides me...
* Replace select backends with poll backends. selscan() and pollscan()millert2003-09-231-8/+8
| | | | | | | now call the poll backend. With this change we implement greater poll(2) functionality instead of emulating it via the select backend. Adapted from NetBSD and including some changes from FreeBSD. Tested by many, deraadt@ OK
* change arguments to suser. suser now takes the process, and a flagstedu2003-08-151-2/+2
| | | | | | | | | argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@
