85c9dd9d89 Prevent overflow issues in timeout processing
Previously, any timeout value for which (timeout * hz) will overflow the
signed integer, will give weird results, since callout(9) routines will
convert negative values of ticks to '1'. For unsigned integer overflow we
will get sufficiently smaller timeout values than expected.

Switch from callout_reset, which requires conversion to int based ticks
to callout_reset_sbt to avoid this.

Also correct isci to correctly resolve ccb timeout.

This was based on the original work done by Eygene Ryabinkin
<rea@freebsd.org> back in 5 Aug 2011 which used a macro to help avoid
the overlow.

04584935bc Various fixes to hptrr(4):
- Use the existing vbus locks instead of Giant for the CAM sim lock.
- Use callout(9) instead of timeout(9).
- Mark the interrupt handler MPSAFE.
- Don't attempt to pass data in the softc from probe() to attach().
- Remove compat shims for FreeBSD versions older than 8.0.

7634a04b30 Apply vendor fixes to the High Point drivers:
- Don't call xpt_free_path() in os_query_remove_device() and
   always return TRUE.
 - Update os_buildsgl() to support build logical SG table which
   will be used by lower RAID module.
 - Return CAM_SEL_TIMEOUTstatus for SCSIcommand failed as target
   missing.

Many thanks to HighPoint for providing this driver update.

eb8a7632ba Re-do r255853. Along with adding back the API/ABI changes from the
original, this hides the contents of cam_compat.h from ktrace/kdump/truss,
avoiding problems there.  There are no user-servicable parts in there, so
no need for those tools to be groping around in there.

185884259b Update the CAM API for FreeBSD 10:
- Remove the timeout_ch field.  It's been deprecated since FreeBSD 7.0;
  MPSAFE drivers should be managing their own timeout storage.  The
  remaining non-MPSAFE drivers have been modified to also manage their own
  storage, and should be considered for updating to MPSAFE (or removal)
  during the FreeBSD 10.x lifecycle.

- Add fields related to soft timeouts and quality of service, to be used
  in upcoming work.

- Add room for more flags in the CCB header and path_inq structures.

- Begin support for extended 64-bit LUNs.

- Bump the CAM version number to 0x18, but add compat shims.  Tested with
  camcontrol and smartctl.

e5dfa058da MFprojects/camlock r248982:
Stop abusing xpt_periph in random plases that really have no periph related
to CCB, for example, bus scanning.  NULL value is fine in such cases and it
is correctly logged in debug messages as "noperiph".  If at some point we
need some real XPT periphs (alike to pmpX now), quite likely they will be
per-bus, and not a single global instance as xpt_periph now.

dd0b4fb6d5 Reform the busdma API so that new types may be added without modifying
every architecture's busdma_machdep.c.  It is done by unifying the
bus_dmamap_load_buffer() routines so that they may be called from MI
code.  The MD busdma is then given a chance to do any final processing
in the complete() callback.

The cam changes unify the bus_dmamap_load* handling in cam drivers.

The arm and mips implementations are updated to track virtual
addresses for sync().  Previously this was done in a type specific
way.  Now it is done in a generic way by recording the list of
virtuals in the map.

83c5d981ac MFp4: Large set of CAM inprovements.
- 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.

c43ee88764 Introduce hw.hptrr.attach_generic loader tunable to deny hptrr driver
attach chips with generic Marvell (non-HighPoint) PCI identification.
These chips are also supported by ata(4). Some vendors, like Supermicro,
are using same chips without providing HPT RAID BIOS.

7d845dde8d Remove build timestamps from the following files:
/boot/kernel/hptrr.ko
/etc/mail/*.cf
/lib/libcrypto.so.5
/usr/bin/ntpq
/usr/sbin/amd
/usr/sbin/iasl
/usr/sbin/ntpd
/usr/sbin/ntpdate
/usr/sbin/ntpdc

There does not appear to be any purpose to having these timestamps, and
they have the irritating consequence that the aforementioned files will
be different every time they are rebuilt.

After this commit, the only remaining build timestamps are in the kernel,
the boot loaders, /usr/include/osreldate.h (the year in the copyright
notice), and lib*.a (the timestamps on all of the included .o files).

9d6a74eb84 Fix a mistake made during the import of the driver. Previous versions of
HPT drivers would sometimes test the value of a preprocessor definition but
not always make sure that the definition existed in the first place, leading
to warnings on newer compilers.  I blindly assumed the same with this driver,
and it turned out to be wrong and to enable some code that doesn't work.
