* - Overhaul the software interrupt code to use interrupt threads for eachjhb2000-10-251-5/+8
| | | | | | | | | | | | | | | | | | | type of software interrupt. Roughly, what used to be a bit in spending now maps to a swi thread. Each thread can have multiple handlers, just like a hardware interrupt thread. - Instead of using a bitmask of pending interrupts, we schedule the specific software interrupt thread to run, so spending, NSWI, and the shandlers array are no longer needed. We can now have an arbitrary number of software interrupt threads. When you register a software interrupt thread via sinthand_add(), you get back a struct intrhand that you pass to sched_swi() when you wish to schedule your swi thread to run. - Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit more intuitive. Also, prefix all the members of struct intrhand with 'ih_'. - Make swi_net() a MI function since there is now no point in it being MD. Submitted by: cp

* Convert DEVFS hooks in (most) drivers to make_dev().phk1999-08-231-17/+0
| | | | | | | | | | | | | | | | 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().

| | | | | | | | | | corresponding variable `rc_wakeup_started' in rev.1.36 but broken again in rev.1.37. This bug only caused excessive polling (it gave NRC activations for each of the SWI handler and the timeout handler instead of 1 of each). Moved cdevsw attachment from the driver probe routine to the driver attach routine.
* Simplify cdevsw registration.phk1999-05-311-16/+4
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* This commit should be a extensive NO-OP:phk1999-05-301-6/+20
| | | | | | | | | | | | | 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.

Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.

| | | | | | | | | | | | | | | | | | | | | | | most devsw referenced functions are now static, as they are in the same file as their devsw structure. I've also added DEVFS support for nearly every device in the system, however many of the devices have 'incorrect' names under DEVFS because I couldn't quickly work out the correct naming conventions. (but devfs won't be coming on line for a month or so anyhow so that doesn't matter) If you "OWN" a device which would normally have an entry in /dev then search for the devfs_add_devsw() entries and munge to make them right.. check out similar devices to see what I might have done in them in you can't see what's going on.. for a laugh compare conf.c conf.h defore and after... :) I have not doen DEVFS entries for any DISKSLICE devices yet as that will be a much more complicated job..
