f94dfeb481 Separate the hardware definitions into ipsreg.h so they can be used by
future userland tools.

2eea70515c Overhaul error handling in the IPS driver. Don't use a magic value for
driver-induced errors, instead be better about propagating error status
upwards.  Add more error definitions, courtesy of the linux driver.  Fix
a command leak in the ioctl handler.  Re-arrange some of the command handlers
to localize error handling.

d4fcf3cba5 Remove bus_{mem,p}io.h and related code for a micro-optimization on i386
and amd64.  The optimization is a trivial on recent machines.

7765040ebc Add crashdump support to the ips driver. It only works for the more modern
ServeRAID 4 - 7 models right now.  Support for older cards is possible, but
I don't have any hardware to experiment with.

Thanks to Jack Hammer at Adaptec for providing debugging hints.

03a908f2ce Lock the IPS driver and bring it out from under Giant. Also do some
significant clean up and optimizations:
- don't call bioq_disksort() on every command, the hardware will do that for
  us.
- remove all of the complicated bio deferral code.  bio's that can't be
  serviced immediately can just wait on the bioq.
- Only reserve one command object for doing control commands to the card.
  This simplifies a lot of code and significantly reduces the size of the
  command struct.
- Allocate commands out of a slab instead of embedding them into the softc.
- Call the command action method directly instead of having ips_get_free_cmd()
  call it indirectly.

b234a120c8 Switch from using mutexes to using semaphores to protect against early
completion of synchronous commands.  Also switch to a per-array bioq as it
appears to improve performance.

7633e7f1a2 ServeRaid (at least 5i) didn't initialize correctly. To get
them working (cache, automatic rebuild and hotswap) the FFDC
info (First Failure Data Capture) on the adapter must be
initialised.

Logical drives in critical/degraded states weren't added to
the drive list. FreeBSD was not able to see a degraded array
after a reboot. Degraded drives are now also added to the drivelist
and the state of the logical drive is given at boottime.

The adapter type is detected from informations in nvram page 5
and displayed at boottime.

Change IPS_OS_FREEBSD definition from 10 to 8 according to IBM
specs.

77e6a3b2dd Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

dea4622d59 - Zero the buffers used to hold configuration data from the card. Not doing
so can leave stale data in the buffer and confuse the driver.
- enable the ability to set the 'disable' hint for the driver to keep it
  from attaching.  i.e. 'hw.ips.0.disable=1' will prevent the driver from
  attaching.
- Only detach if attach suceeded.

2aedd662d8 Add the 'ips' driver for the IBM (now Adaptec) ServeRAID controller
series.  This driver was generously developed and released by David
Jeffreys and Adaptec.  I've updated it to work with 5.x and fixed a
few bugs.
