* 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.

* Fix warnings on non-i386 arch.Hidetoshi Shimokawa2004-10-141-0/+2
| | | | | | | Submitted by: keramida Notes: svn path=/head/; revision=136498
* - Split dcons core code and OS dependent code.Hidetoshi Shimokawa2004-10-135-650/+883
| | | | | | | | | - Implement dcons_ischar() and dcons_load_buffer(). - If loader passed a dcons buffer address, keep using it. (We still need a patch to cheat memory management system.) Notes: svn path=/head/; revision=136467
* Invalidate dcons buffer on shutdown.Hidetoshi Shimokawa2004-09-261-0/+1

* 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
* Do a pass over all modules in the kernel and make them return EOPNOTSUPPPoul-Henning Kamp2004-07-151-0/+3
| | | | | | | | | | | for unknown events. A number of modules return EINVAL in this instance, and I have left those alone for now and instead taught MOD_QUIESCE to accept this as "didn't do anything". Notes: svn path=/head/; revision=132199

* Update for the KDB framework:Marcel Moolenaar2004-07-101-49/+4
| | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=131912
* Second half of the dev_t cleanup.Poul-Henning Kamp2004-06-171-1/+1
| | | | | | | | | | | | | | The big lines are: NODEV -> NULL NOUDEV -> NODEV udev_t -> dev_t udev2dev() -> findcdev() Various minor adjustments including handling of userland access to kernel space struct cdev etc. Notes: svn path=/head/; revision=130640

| | | | | | | | | linesw[] directly to using the ttyld...() functions The ttyld...() functions ar inline so there is no performance hit. Notes: svn path=/head/; revision=130077
* Gainfully employ the new ttyioctl in the trivial cases.Poul-Henning Kamp2004-06-011-25/+0

* There is no need to explicitly call ttwakeup() and ttwwakeup() afterPoul-Henning Kamp2004-06-011-2/+0
| | | | | | | | ttyclose() has been called. It's already been done once by ttyclose, and probably once by the line-discipline too. Notes: svn path=/head/; revision=129937
* ttyclose() increments t_gen. Remove redundant increments in drivers.Poul-Henning Kamp2004-06-011-1/+0

* Device megapatch 4/6:Poul-Henning Kamp2004-02-211-1/+2
| | | | | | | | | | | 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
* Device megapatch 3/6:Poul-Henning Kamp2004-02-211-3/+1
| | | | | | | | | | | | | | | Add missing D_TTY flags to various drivers. Complete asserts that dev_t's passed to ttyread(), ttywrite(), ttypoll() and ttykqwrite() have (d_flags & D_TTY) and a struct tty pointer. Make ttyread(), ttywrite(), ttypoll() and ttykqwrite() the default cdevsw methods for D_TTY drivers and remove the explicit initializations in various drivers cdevsw structures. Notes: svn path=/head/; revision=126078
* Device megapatch 1/6:Poul-Henning Kamp2004-02-211-2/+0
| | | | | | | | | | Free approx 86 major numbers with a mostly automatically generated patch. A number of strategic drivers have been left behind by caution, and a few because they still (ab)use their major number. Notes: svn path=/head/; revision=126076
* - Clean up global data.Hidetoshi Shimokawa2004-02-163-38/+58
