Enable the vn device under DEVFS without SLICE. 1998-09-12T18:46:06Z Søren Schmidt sos@FreeBSD.org 1998-09-12T18:46:06Z urn:sha1:8b90e70e7746c94927a17222533542561134a46f This was apparently missed when all the #ifdef SLICE gunk was put in. remove bdevsw arg from dsopen(); 1998-08-23T20:16:35Z Poul-Henning Kamp phk@FreeBSD.org 1998-08-23T20:16:35Z urn:sha1:be18fc123b4c937a647f5ec085502f76c368875f Forgotten by: julian Reviewed by: bde Make struct buf->b_offset reflect the real byte offset which got 1998-08-19T10:50:32Z Søren Schmidt sos@FreeBSD.org 1998-08-19T10:50:32Z urn:sha1:e620a1cbed83659da9ffb5141a053d1ee3a4b552 in via the uio struct. This enables device drivers to use != DEV_BSIZE blocking on devices with wierd sector/block sizes (ie CDROM's). Added a flags arg to dsopen() and updated drivers. The DSO_ONESLICE 1998-07-30T15:16:06Z Bruce Evans bde@FreeBSD.org 1998-07-30T15:16:06Z urn:sha1:34e9dea4352bcc3ca6fb798cc4519addb8a47fe1 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. SLICE probing becomes asynchronous.

This needs a lot of cleanup, but has been working here for a month or two.. originally needed for CAM integration but that hasn't happenned yet. The probing state machines for each handler should be replaced by a more generic state-service. It's still quite messy in there.. Fixed printf format errors. 1998-07-11T07:46:16Z Bruce Evans bde@FreeBSD.org 1998-07-11T07:46:16Z urn:sha1:ac1e407b32ad79ecad415cd6d0955f90ba53efc2 There is no such thing any more as "struct bdevsw". 1998-07-04T22:30:26Z Julian Elischer julian@FreeBSD.org 1998-07-04T22:30:26Z urn:sha1:f7ea2f55d11712e31e448896b4d1bda81be24e35 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.
