Change from lkm to kld
Add field plexsdno to sd struct
Add flag VF_NEWBORN to drive, sd, plex and volume structs, indicating
that the object has just been created.
Add object types for raw (unattached) plexes and subdisks
Remove definitions of VOLNO, PLEXNO and SDNO (now functions Volno,
Plexno and Sdno)
Move revive parameters from struct plex to struct sd.
struct plex:
maintain a count of the number of inaccessible subdisks.
remove defective and unmapped regions.
Debug flags: make an enum (previously #define)
Set default revive block size to 64kB (was 32 kB)
Previously, accidentally starting the wrong version could corrupt
the RAID5 configuration.
Add functions Volno, Plexno and Sdno to replace the old defines
VOLNO, PLEXNO and SDNO.
Change from lkm to kld
Serious rewrite. No longer call set_<foo>_state to set the state
based only on other objects; instead, add functions
update_<foo>_state, which determine what the state should be by
themselves. This allows the set_<foo>_state functions to shrink
enough to be almost intelligible.
Remove flags setstate_recurse and setstate_recursing.
Remove plex defective regions and unmapped regions, which were
maintained but not used.
Change code to allow daemon to perform operations formerly kludged
into an interrupt context. Remove the DIRTYCONFIG kludge.
Change from lkm to kld
Remove #ifdefs for FreeBSD 2.c
vinumstrategy:
Support anonymous (`raw') subdisks and plexes.
Change code to allow daemon to perform operations formerly kludged
into an interrupt context. Remove the DIRTYCONFIG kludge.
No longer set B_ORDERED for reviving subdisks. I suspect this
wouldn't work correctly, and it should be done in a different manner
in vinumrevive.c
sdio: set subdisk state correctly on error
start to remove code that doesn't make any sense any more.
Remove #ifdefs for FreeBSD 2.c
Change from lkm to kld
correct type of `flags' in calls to set_drive_state.
set_drive_parms: handle anonymous drives correctly (remove them)
drive VOP functions: use the PID of the original opener to fool the
lock manager.
open_drive: be quiet about failures (they're normal when scanning the
partitions).
close_drive: lock drive before closing.
remove_drive: lock drive before deallocating.
read_drive_label: set drive up when all is OK
check_drive:
Complete rewrite. Offload most of the code to the new
vinum_scandisk
format_config:
use snprintf and %qd options to make much less emetic.
Remove old supporting functions.
vinum_scandisk:
Moved here from vinum.c
Almost complete rewrite, incorporating much of what was check_drive.
We still don't have a general way to find the drives on a system, so
get the user to supply the names via the `read' command. For each
device, try each possible compatibility slice name (there's a danger
of finding both /dev/da1h and /dev/da0s1h otherwise). Sort the
partitions found in reverse order of last update time and read them
in, setting the `update' parameter to parse_config and descendents.
save_config: rename to daemon_save_config, since the function is now
called by the daemon. Create a new function save_config which queues
the request with the daemon.
daemon_save_config: some mods to allow for the unfamiliar
environment.
Change from lkm to kld
Remove BROKEN_GDB kludge (it's not needed with klds)
Add code for interfacing with daemon
Modify device minor number encoding, use selector functions which also
permit anonymous plexes and subdisks.
Remove code for 2.x support.
Change messages to omit obvious words like 'plex' and 'subdisk.
give_plex_to_volume: invalidate subdisks being given to a plex which
is part of a volume with other plexes.
give_sd_to_plex: keep track of plex size in all cases
lock drives before closing them, to keep the daemon from getting
confused.
config_drive: handle partition type errors more gracefully
config_subdisk: set subdisk state correctly
find_drive, find_drive_by_dev, find_subdisk, find_plex, find_volume:
set VF_NEWBORN flag when a new object is created
config_drive:
Handle partition_status returns more cleverly.
Replace the device name in some cases where it got overwritten.
config_subdisk:
add parameter `update'. If the object already exists, exit without
any changes.
Set state correctly.
config_plex, config_volume:
add parameter `update'. If the object already exists, exit without
any changes.
parse_config:
move read function to vinum_scandisk.
add parameter `update' to pass to config_<object>.
remove_<object>_entry:
print a message when the object is removed.
update_plex_config:
Start defusing this function, which will go away some time.
Remove calls to update_volume_config.
Make size 64 bits
Change from lkm to kld
Remove BROKEN_GDB kludge (it's not needed with klds)
Add code for interfacing with daemon
Modify manner of determining when module is idle
Modify device minor number encoding, use selector functions which also
permit anonymous plexes and subdisks.
Remove code for 2.x support.
Move vinum_scandisk to vinumio.c
Remove myproc kludge
Keep track of open volumes by flag, not by pid (the pids caused some
problems with the lock manager).
free_vinum:
Remove unmapped and defective regions from plexes.
Wait for daemon to stop before returning
vinumopen:
Don't refuse an open if the volume is already open.
pnp system in freebsd, I'm not sure how useful this will be, but my
1542CP seems to work well in plug and play mode and does seem to
probe correctly at all the oddball addresses/irq/drqs that I tried.
[[
I was unable to get /kernel.conf or /kernel.config to read in, so
I wasn't able to verify that this method of userconfig works. that's
one thing that makes pnp so hard to use in the current scheme.
Pointers to the right new way of doing this accepted.

o Add some kludges to maybe bring support for 1540A/1542A into the
driver. Since I have no 154xA cards, and the only person I know
that has them hasn't given me feedback, I'm making this commit
blind.
o Honor unit numbers that are in the config file now. This allows one
to hard wire the unit numbers (and have high unit numbers for plug
and pray devices, which can't seem to be hardwired) and have the
cards not migrate from aha1 -> aha0 should aha0 go on the fritz. I
didn't verify that hard wired scsi busses would work, but did verify
that hard wired aha addresses did work to a limited extent. Both
aha0 and aha1 must be hardwired, or when the card that was in aha0
goes away, the probe for aha0 might pick up the card that otherwise
would have been aha1.
The previous code just ignored the invalid map register, but this gave
surprising results because of the way pci_map_port() associated the map
register offset supplied with a map entry in the map array.
- Bring down the splash screen when a vty is opened for the first
time.
- Make sure the splash screen/screen saver is stopped before
switching vtys.
- Read and save initial values in the BIOS data area early.
VESA BIOS may change BIOS data values when switching modes.
- Fix missing '&' operator.
- Move ISA specific part of driver initialization to syscons_isa.c.

- Adjust for forthcoming alpha port. Submitted by: dfr
reorganization in rev 1.16 of i386/include/types.h which changed
stdlib.h's use of <machine/types.h>. The problem was the -I. was causing
machine/types.h to come from the current kernel source, while stdlib.h was
coming from /usr/include. /usr/include/stdlib.h is as old as the last
'make world', the machine/types.h was as new as the current source.
0 success
EAGAIN try again later

- Test flags consistently to examine the status of the screen saver.
scrn_blanked: the screen saver is running
scp->status & SAVER_RUNNING: the saver is running in this vty
- Correctlyu preserve status flag bits in set/restore_scrn_saver_mdoe().
if option CY_PCI_FASTINTR is configured and mapping the irq to a
fastintr is possible. Unfortunately, this has to be optional because
pci_map_int_right() doesn't handle the INTR_EXCL flag right --
INTR_EXCL is honoured even if the interrupt needs to be non-exclusive
for other devices to work.
buffer had to be left on the head of the queue for [bufq]disksort()
to sort against. This isn't right for devices that can support multiple
active i/o's, and only the fd driver did it. "Fixing" this in rev.1.36
of ufs_disksubr.c broke the fd driver in much the same way as rev.1.52
of <sys/buf.h> broke it (see rev.1.119).
Bug reported and fix tested by: dt
black hole device. The controller will now only accept selections if
the black hole device is present and some other target/lun is enabled
for target mode.
Handle the IGNORE WIDE RESIDUE message. This support has not been tested.
Checkpoint work on handling ABORT, BUS DEVICE RESET, TERMINATE I/O PROCESS,
and CLEAR QUEUE messages as a target.
Fix a few problems with tagged command handling in target mode.
Wait until the sync offset counter falls to 0 before changing phase
after a data-in transfer completes as the DMA logic seems to indicate
transfer complete as soon as our last REQ is issued.
Simplify some of the target mode message handling code in the sequencer.
