2016-08-19Remove the scd(4) driver for Sony CDU31/33 CD-ROM drives.John Baldwin
This is a driver for a pre-ATAPI ISA CD-ROM adapter. The driver only uses PIO. Notes: svn path=/head/; revision=304498
2016-04-26sys/dev: extend use of the howmany() macro when available.Pedro F. Giffuni
We have a howmany() macro in the <sys/param.h> header that is convenient to re-use as it makes things easier to read. Notes: svn path=/head/; revision=298646
2014-11-18Add locking to scd(4) and mark MPSAFE.John Baldwin
- Actually use existing per-softc mutex. - Use mutex in cdev routines and remove D_NEEDGIANT. - Use callout(9) instead of timeout(9). - Don't check for impossible conditions (e.g. SCDINIT being clear). - Use bus_*() instead of bus_space_*(). Tested by: no one Notes: svn path=/head/; revision=274679

2005-03-02netchild's mega-patch to isolate compiler dependencies into a centralJoerg Wunsch
place. This moves the dependency on GCC's and other compiler's features into the central sys/cdefs.h file, while the individual source files can then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42. By now, GCC and ICC (the Intel compiler) have been actively tested on IA32 platforms by netchild. Extension to other compilers is supposed to be possible, of course.

2005-01-30Boot away another stackgap (one of the lest ones in linuxlator/i386) byMaxim Sobolev
providing special version of CDIOCREADSUBCHANNEL ioctl(), which assumes that result has to be placed into kernel space not user space. In the long run more generic solution has to be designed WRT emulating various ioctl()s that operate on userspace buffers, but right now there is only one such ioctl() is emulated, so that it makes little sense.

2004-03-12These are changes to allow to use the Intel C/C++ compiler (lang/icc)Tom Rhodes

Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as icc v8 may define __GNUC__ some parts may look strange but are necessary.

<sys/bio.h>. <sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall not be made a nested include according to bdes teachings on the subject of nested includes. Diskdrivers and similar stuff below specfs::strategy() should no longer need to include <sys/buf.> unless they need caching of data. Still a few bogus uses of struct buf to track down.

2000-04-02Move B_ERROR flag to b_ioflags and call it BIO_ERROR.Poul-Henning Kamp
(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. Notes: svn path=/head/; revision=58934
2000-03-20Remove B_READ, B_WRITE and B_FREEBUF and replace them with a newPoul-Henning Kamp
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. Notes: svn path=/head/; revision=58345

1999-08-23Convert DEVFS hooks in (most) drivers to make_dev().Poul-Henning Kamp
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
1999-05-31Simplify cdevsw registration.Poul-Henning Kamp
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
1999-05-30This commit should be a extensive NO-OP:Poul-Henning Kamp
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.
