* Convert DEVFS hooks in (most) drivers to make_dev().phk1999-08-231-27/+7
| | | | | | | | | | | | | | | | 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().
* Simplify cdevsw registration.phk1999-05-311-18/+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:phk1999-05-301-4/+21
| | | | | | | | | | | | | 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.

| | | | | | | | | | FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. 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.

* Apparently, someone changed the gsc driver to allocate one big bufferjoerg1996-12-301-1/+0
| | | | | | | | | | | | at device attach time, instead of allocating and freeing buffers as necessary. But he or she forgot to remove the line that invalidated the buffer when the device is closed. Therefore, after using the device for the first time, the buffer was incorrectly invalidated and that caused a page fault on the second, and subsequent uses.

* Pass 3 of the great devsw changesjulian1995-12-081-35/+60
| | | | | | | | | | | | | | | | | | | | | | | 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.. (pass 5 :) pass 4 will be to make the devsw tables of type (cdevsw * ) rather than (cdevsw) seems to work here.. complaints to the usual places.. :)

* OK, that's it..julian1995-11-291-14/+24
| | | | | | | | | | | | | | | | | | | | | | | | That's EVERY SINGLE driver that has an entry in conf.c.. my next trick will be to define cdevsw[] and bdevsw[] as empty arrays and remove all those DAMNED defines as well.. Each of these drivers has a SYSINIT linker set entry that comes in very early.. and asks teh driver to add it's own entry to the two devsw[] tables. some slight reworking of the commits from yesterday (added the SYSINIT stuff and some usually wrong but token DEVFS entries to all these devices. BTW does anyone know where the 'ata' entries in conf.c actually reside? seems we don't actually have a 'ataopen() etc... If you want to add a new device in conf.c please make sure I know so I can keep it up to date too.. as before, this is all dependent on #if defined(JREMOD) (and #ifdef DEVFS in parts)

By the end of this, linked in drivers will be exactly the same as run-time loaded drivers, except they JUST HAPPEN to already be linked and present at startup.. the SYSINIT calls will be the equivalent of the "init" call made to a newly loaded driver in every respect.
