* Teach GEOM about Sun disklabel formats.phk2002-03-151-0/+209
| | | | | | | | | | The detection code in this method is written so that it should work on all architectures which means that you can plug a Sun disk into a i386 now and access the partitions. We still need an endian-agnostic ufs/ffs before this is really interresting, but the main focus was to get sparc64 onto the GEOM trail.

* Introduce the new 64-bit size disk block, daddr64_t. Changemckusick2002-03-151-1/+1
| | | | | | | | | | | | the bio and buffer structures to have daddr64_t bio_pblkno, b_blkno, and b_lblkno fields which allows access to disks larger than a Terabyte in size. This change also requires that the VOP_BMAP vnode operation accept and return daddr64_t blocks. This delta should not affect system operation in any way. It merely sets up the necessary interfaces to allow the development of disk drivers that work with these larger disk block addresses. It also allows for the development of UFS2 which will use 64-bit block addresses.

| | | | | | | | | | | | | | | | | | cloning infrastructure standard in kern_conf. Modules are now the same with or without devfs support. If you need to detect if devfs is present, in modules or elsewhere, check the integer variable "devfs_present". This happily removes an ugly hack from kern/vfs_conf.c. This forces a rename of the eventhandler and the standard clone helper function. Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include like <sys/queue.h> Remove all #includes of opt_devfs.h they no longer matter.

* Move the truncation code out of vn_open and into the open system callmckusick2000-07-041-2/+3
| | | | | | | | | | after the acquisition of any advisory locks. This fix corrects a case in which a process tries to open a file with a non-blocking exclusive lock. Even if it fails to get the lock it would still truncate the file even though its open failed. With this change, the truncation is done only after the lock is successfully acquired.

| | | | | | | | | | | | | | | | | | | | | 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.

* Revamp the devstat priority system. All disks now have the same priority.ken1999-12-081-2/+2
| | | | | | | | | | | | | | | | | | The same goes for CD drivers and tape drivers. In systems with mixed IDE and SCSI, devices in the same priority class will be sorted in attach order. Also, the 'CCD' priority is now the 'ARRAY' priority, and a number of drivers have been modified to use that priority. This includes the necessary changes to all drivers, except the ATA drivers. Soren will modify those separately. This does not include and does not require any change in the devstat version number, since no known userland applications use the priority enumerations.

| | | | | | | | | | | | | | | Enhance MIRROR code. Add a few more sanity checks and implement a zone-based disk selector to make use of both disks when reading. Also implement a read fail-over. If a read error occurs on one disk, the I/O is retried on the other. NOTE: CCD's mirroring support cannot deal with write errors properly in regards to recovery, meaning that 'old' data under a write error may be read non-deterministically if you reboot after a write error, and CCD certainly cannot deal with a disk changeout. And it still can't. Use vinum if you are really serious about mirroring. CCD basically just implements a poor-man's mirror.
