* Added a flags arg to dsopen() and updated drivers. The DSO_ONESLICEBruce Evans1998-07-301-2/+2
| | | | | | | | | | | | | | and DSO_NOLABELS flags prevent searching for slices and labels respectively. Current drivers don't set these flags. When DSO_NOLABELS is set, the in-core label for the whole disk is cloned to create an in-core label for each slice. This gives the correct result (a good in-core label for the compatibility slice) if DSO_ONESLICE is set or only one slice is found, but usually gives broken labels otherwise, so DSO_ONESLICE should be set if DSO_NOLABELS is set.

The probing state machines for each handler should be replaced by a more generic state-service. It's still quite messy in there.. Notes: svn path=/head/; revision=37616

* There is no such thing any more as "struct bdevsw".Julian Elischer1998-07-041-8/+26
| | | | | | | | | | | | | | | | | | | | | 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.

* This commit fixes various 64bit portability problems required forDoug Rabson1998-06-071-6/+6
| | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=36735
* An effort to make SLICE/DEVFS play with SCSI.Julian Elischer1998-05-071-79/+102
| | | | | | | | | | | Apparently I didn't make my plans to make dev_t and devsw[] go away under DEVFS quite clear enough to Peter Dufault as he stitched the SCSI system together using them when he redid the configuration side of things. This made is rather an effort to remove all vestiges of dev_t and devsw[] entries from sd.c in DEVFS/SLICE mode. Notes: svn path=/head/; revision=35827

* Add changes and code to implement a functional DEVFS.Julian Elischer1998-04-191-6/+207
| | | | | | | | | | | | | | | | | | | | | | | | This code will be turned on with the TWO options DEVFS and SLICE. (see LINT) Two labels PRE_DEVFS_SLICE and POST_DEVFS_SLICE will deliniate these changes. /dev will be automatically mounted by init (thanks phk) on bootup. See /sys/dev/slice/slice.4 for more info. All code should act the same without these options enabled. Mike Smith, Poul Henning Kamp, Soeren, and a few dozen others This code does not support the following: bad144 handling. Persistance. (My head is still hurting from the last time we discussed this) ATAPI flopies are not handled by the SLICE code yet. When this code is running, all major numbers are arbitrary and COULD be dynamically assigned. (this is not done, for POLA only) Minor numbers for disk slices ARE arbitray and dynamically assigned.

Also don't print out worrying bogus messages when probing a device that has no media. There's no point in printing out something that is unknowable. It just confuses things.

Instead, call scsi_start_unit() once in sd_attach(), so in case the drive has been configured to `remote start', it will spin up there. (If it has spun down later, it must have been because of administrator action (scsi(8)) anyway.) While i was at it, bump the timeout for scsi_start_unit() to 30 seconds. 10 seconds were way too few for most drives. Notes: svn path=/head/; revision=30321

Currently sectors of size 512, 1024 & 2048 are supported, the only restriction beeing in fdisk, which hunts for the sectorsize of the device. This is based on patches to od.c and the other system files by John Gumb & Barry Scott, minor changes and the sd.c patches by me. There also exist some patches for the msdos filesys code, but I havn't been able to test those (yet).
