2016-08-15Remove the mcd(4) driver for Mitsumi CD-ROM players.John Baldwin
This is a driver for a pre-ATAPI ISA CD-ROM adapter. As noted in the manpage, this driver is only useful as a backend to cdcontrol to play audio CDs since it doesn't use DMA, so its data performance is "abysmal" (and that was true in the mid 90's). Notes: svn path=/head/; revision=304187
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 mcd(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. MCDINIT being clear). - Remove critical_enter/exit when sending a PIO command. - Use bus_*() instead of bus_space_*().

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.

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.

Notes: svn path=/head/; revision=104545
2002-10-05NB: This commit does *NOT* make GEOM the default in FreeBSDPoul-Henning Kamp
NB: But it will enable it in all kernels not having options "NO_GEOM" Put the GEOM related options into the intended order. Add "options NO_GEOM" to all kernel configs apart from NOTES. In some order of controlled fashion, the NO_GEOM options will be removed, architecture by architecture in the coming days. There are currently three known issues which may force people to need the NO_GEOM option: boot0cfg/fdisk: Tries to update the MBR while it is being used to control slices. GEOM does not allow this as a direct operation. SCSI floppy drives: Appearantly the scsi-da driver return "EBUSY" if no media is inserted. This is wrong, it should return ENXIO. PC98: It is unclear if GEOM correctly recognizes all variants of PC98 disklabels. (Help Wanted! I have neither docs nor HW) These issues are all being worked. Sponsored by: DARPA & NAI Labs.

(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.

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!)

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
