Add Power Up In Stand-by feature support. Device with PUIS enabled
require explicit command to do initial spin-up. Mark that command
with CAM_HIGH_POWER flag, to allow CAM manage staggered spin-up.
- Use separate buffer for identify data fetching. We can't use main buffer
here if device already running, as data need to be formatted before use.
- Remove some saved_ccb variables. They are unused now.
- Give ATA/SATA SIMs info about ATAPI packet size, supported by device.
- Make ATA XPT to reject longer SCSI CDBs then supported by device, or
any SCSI CDBs, if device doesn't support ATAPI.
Large set of CAM improvements:
- Unify bus reset/probe sequence. Whenever bus attached at boot or later,
CAM will automatically reset and scan it. It allows to remove duplicate
code from many drivers.
- Any bus, attached before CAM completed it's boot-time initialization,
will equally join to the process, delaying boot if needed.
- New kern.cam.boot_delay loader tunable should help controllers that
are still unable to register their buses in time (such as slow USB/
PCCard/ CardBus devices), by adding one more event to wait on boot.
- To allow synchronization between different CAM levels, concept of
requests priorities was extended. Priorities now split between several
"run levels". Device can be freezed at specified level, allowing higher
priority requests to pass. For example, no payload requests allowed,
until PMP driver enable port. ATA XPT negotiate transfer parameters,
periph driver configure caching and so on.
- Frozen requests are no more counted by request allocation scheduler.
It fixes deadlocks, when frozen low priority payload requests occupying
slots, required by higher levels to manage theit execution.
- Two last changes were holding proper ATA reinitialization and error
recovery implementation. Now it is done: SATA controllers and Port
Multipliers now implement automatic hot-plug and should correctly
recover from timeouts and bus resets.
- Improve SCSI error recovery for devices on buses without automatic sense
reporting, such as ATAPI or USB. For example, it allows CAM to wait, while
CD drive loads disk, instead of immediately return error status.
- Decapitalize diagnostic messages and make them more readable and sensible.
- Teach PMP driver to limit maximum speed on fan-out ports.
- Make boot wait for PMP scan completes, and make rescan more reliable.
- Fix pass driver, to return CCB to user level in case of error.
- Increase number of retries in cd driver, as device may return several UAs.
Add support for SATA part of Marvell 88SE912x controllers to ahci(4).
Limit early revisions from 6Gb/s to 3Gb/s by default, or they negotiate
only 1.5Gb/s, when 3Gb/s devices connected.
Add dummy driver for PATA part of these controllers, preventing generic
driver attach them. It causes system freeze when SATA controller used after
PATA was touched.
Make ata_getrev() an optional method by implementing ata_null_getrev().
This fixes a bogus '???' boot message on Cambria boards with a CompactFlash
card.
Make OSS_GETVERSION ioctl really work. It has 'M' group, not 'P',
as different nearby ones, and was grabbed by MIXER_xxx() handler.
While there, replace '(cmd & MIXER_xxx(0)) == MIXER_xxx(0)' expressions
with more correct '(cmd & ~0xff) == MIXER_xxx(0)'. Use of bit operations
to compare numeric fields doesn't looks sane.
Don't panic on failure to attach if we fail before or during the
if_alloc() of ifp.
This fixes the panic reported in the PRs, but not the attach failure.

Fix a race that can occur when nfs nfsiod threads are being created.
Without this patch it was possible for a different thread that calls
nfs_asyncio() to snitch a newly created nfsiod thread that was
intended for another caller of nfs_asyncio(), because the nfs_iod_mtx
mutex was unlocked while the new nfsiod thread was created. This patch
labels the newly created nfsiod, so that it is not taken by another
caller of nfs_asyncio(). This is believed to fix the problem reported

Instead of spamming the console on each curvnet recursion event, print
out each such call graph only once, along with a stack backtrace. This
should make kernels built with VNET_DEBUG reasonably usable again in
busy / production environments.
Introduce a new DDB command "show vnetrcrs" which dumps the whole log
of distinctive curvnet recursion events. This might be useful when
recursion reports get burried / lost too deep in the message buffer.

Add a timeout for the negative name cache entries in the NFS client.
This avoids a bogus negative name cache entry from persisting forever
when another client creates an entry with the same name within the
same NFS server time of day clock tick. The mount option negnametimeo
can be used to override the default timeout interval on a
per-mount-point basis. Setting negnametimeo to 0 disables negative
name caching for the mount point.
I also fixed one obvious typo where args.timeo should be
args.maxgrouplist.

Overhaul of the pcii driver:
. Properly allocate all IO space resources. These cards scatter their
IO addresses over a range of 0x1600 bytes, and they require an
additional address for "special interrupt handling".
. Implement the "special interrupt handling" per the GPIB-PCIIA
Technical Reference Manual; this was apparently not declared for the
clone card this driver has been originally implemented for, but it
turned out to be needed for both, an original NI brand PCII/PCIIA
card as well as the Axiom AX5488 clone.
. Add some diagnostic messages for various resource allocation etc.
failures during probe.
. Add some comments about the structure of the IO address space that
is used by these cards.

Introduce the new kernel thread called "deadlock resolver".
It is used in order to seek within the threads state and heuristically
understand if there is any deadlock happening.
In order to implement it, the sq_type in sleepqueues is mandatory and not
only compiled along with INVARIANTS option. Additively, a new sleepqueue
function, sleepq_type() is added, returning the type of the sleepqueue
linked to a wchan.
Three new sysctls are added in order to configure the thread:
debug.deadlkres.slptime_threshold
debug.deadlkres.blktime_threshold
debug.deadlkres.sleepfreq
rappresenting the thresholds for sleep and block time that will lead to
a deadlock matching (when exceeded), while the sleepfreq rappresents the
number of seconds between 2 consecutive thread runnings.
In order to enable the deadlock resolver thread recompile your kernel
with the option DEADLKRES.

Add a facility for associating optional descriptions with active interrupt
