* KSE Milestone 2Julian Elischer2001-09-121-3/+3
| | | | | | | | | | | | | | | | | Note ALL MODULES MUST BE RECOMPILED make the kernel aware that there are smaller units of scheduling than the process. (but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process. Sorry john!

* Some newbus-inspired tidy-ups. Use device_identify() rather than scanningPeter Wemm2000-01-231-28/+21
| | | | | | | | | | | | | | | the resource table to locate children. The 'at ppbus?' can go again. Remove a few #if Nxxx > 0' type things, config arranges this for us. Move the newbus method glue next to the DRIVER_MODULE() stuff so we don't need extra prototypes. Don't set device descriptions until after the possibility of the probe returning an error. Remove all cdevsw_add() calls, all the drivers that did this also use make_dev() correctly, so it's not required. A couple of other minor nits. Notes: svn path=/head/; revision=56455
* Port of ppbus standalone framework to the newbus system.Nicolas Souchu2000-01-141-157/+194
| | | | | | | | | | | | | | | | | | | | | | | | Note1: the correct interrupt level is invoked correctly for each driver. For this purpose, drivers request the bus before being able to call BUS_SETUP_INTR and BUS_TEARDOWN_INTR call is forced by the ppbus core when drivers release it. Thus, when BUS_SETUP_INTR is called at ppbus driver level, ppbus checks that the caller owns the bus and stores the interrupt handler cookie (in order to unregister it later). Printing is impossible while plip link is up is still TRUE. vpo (ZIP driver) and lpt are make in such a way that using the ZIP and printing concurrently is permitted is also TRUE. Note2: specific chipset detection is not done by default. PPC_PROBE_CHIPSET is now needed to force chipset detection. If set, the flags 0x40 still avoid detection at boot. Port of the pcf(4) driver to the newbus system (was previously directly connected to the rootbus and attached by a bogus pcf_isa_probe function). Notes: svn path=/head/; revision=55939

* Convert DEVFS hooks in (most) drivers to make_dev().Poul-Henning Kamp1999-08-231-18/+5
| | | | | | | | | | | | | | | | | | | Diskslice/label code not yet handled. Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers) Add the correct hook for devfs to kern_conf.c The net result of this excercise is that a lot less files depends on DEVFS, and devtoname() gets more sensible output in many cases. A few drivers had minor additional cleanups performed relating to cdevsw registration. A few drivers don't register a cdevsw{} anymore, but only use make_dev(). Notes: svn path=/head/; revision=50254

* Simplify cdevsw registration.Poul-Henning Kamp1999-05-311-17/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The cdevsw_add() function now finds the major number(s) in the struct cdevsw passed to it. cdevsw_add_generic() is no longer needed, cdevsw_add() does the same thing. cdevsw_add() will print an message if the d_maj field looks bogus. Remove nblkdev and nchrdev variables. Most places they were used bogusly. Instead check a dev_t for validity by seeing if devsw() or bdevsw() returns NULL. Move bdevsw() and devsw() functions to kern/kern_conf.c Bump __FreeBSD_version to 400006 This commit removes: 72 bogus makedev() calls 26 bogus SYSINIT functions if_xe.c bogusly accessed cdevsw[], author/maintainer please fix. I4b and vinum not changed. Patches emailed to authors. LINT probably broken until they catch up. Notes: svn path=/head/; revision=47640
* This commit should be a extensive NO-OP:Poul-Henning Kamp1999-05-301-5/+22
| | | | | | | | | | | | | | | | Reformat and initialize correctly all "struct cdevsw". Initialize the d_maj and d_bmaj fields. The d_reset field was not removed, although it is never used. I used a program to do most of this, so all the files now use the same consistent format. Please keep it that way. Vinum and i4b not modified, patches emailed to respective authors.
