| | | | | | | | | | Exceptions: Vinum untouched. This means that it cannot be compiled. Greg Lehey is on the case. CCD not converted yet, casts to struct buf (still safe) atapi-cd casts to struct buf to examine B_PHYS

| | | | | | | | | | | | | (Much of this done by script) Move B_ORDERED flag to b_ioflags and call it BIO_ORDERED. Move b_pblkno and b_iodone_chain to struct bio while we transition, they will be obsoleted once bio structs chain/stack. Add bio_queue field for struct bio aware disksort. Address a lot of stylistic issues brought up by bde.
* Remove B_READ, B_WRITE and B_FREEBUF and replace them with a newphk2000-03-201-1/+1
| | | | | | | | | | | | | | | | | | | | | field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set. B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes. Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL. Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading. This change is a step in the direction towards a stackable BIO capability. A lot of this patch were machine generated (Thanks to style(9) compliance!) Vinum users: Greg has not had time to test this yet, be careful.

* Convert DEVFS hooks in (most) drivers to make_dev().phk1999-08-231-37/+6
| | | | | | | | | | | | | | | | 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.phk1999-05-311-17/+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.

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.

* There is no such thing any more as "struct bdevsw".julian1998-07-041-11/+19
| | | | | | | | | | | | | | | | | | There is only cdevsw (which should be renamed in a later edit to deventry or something). cdevsw contains the union of what were in both bdevsw an cdevsw entries. The bdevsw[] table stiff exists and is a second pointer to the cdevsw entry of the device. it's major is in d_bmaj rather than d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw). rawread()/rawwrite() went away as part of this though it's not strictly the same patch, just that it involves all the same lines in the drivers. cdroms no longer have write() entries (they did have rawwrite (?)). tapes no longer have support for bdev operations.

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.

* This mega-commit brings the following:joerg1997-05-041-2/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | . It makes cd9660 root f/s working again. . It makes CD9660 a new-style option. . It adds support to mount an ISO9660 multi-session CD-ROM as the root filesystem (the last session actually, but that's what is expected behaviour). Sigh. The CDIOREADTOCENTRYS did a copyout() of its own, and thus has been unusable for me for this work. Too bad it didn't simply stuff the max 100 entries into the struct ioc_read_toc_entry, but relied on a user supplied data buffer instead. :-( I now had to reinvent the wheel, and created a CDIOREADTOCENTRY ioctl command that can be used in a kernel context. While doing this, i noticed the following bogosities in existing CD-ROM drivers: wcd: This driver is likely to be totally bogus when someone tries two succeeding CDIOREADTOCENTRYS (or now CDIOREADTOCENTRY) commands with requesting MSF format, since it apparently operates on an internal table. scd: This driver apparently returns just a single TOC entry only for the CDIOREADTOCENTRYS command. I have only been able to test the CDIOREADTOCENTRY command with the cd(4) driver. I hereby request the respective maintainers of the other CD-ROM drivers to verify my code for their driver. When it comes to merging this CD-ROM multisession stuff into RELENG_2_2 i will only consider drivers where i've got a confirmation that it actually works.

| | | | | | | | | | | | | | | | | | | | | | | 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.. :)
