AACRAID(4) BSD Kernel Interfaces Manual AACRAID(4)NAME
aacraid -- Adaptec AACRAID Controller driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device pci
device aacraid
To compile in debugging code:
options AACRAID_DEBUG=N
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
aacraid_load="YES"
DESCRIPTION
The aacraid driver provides support for the Adaptec by PMC RAID controllers, including Series 6/7/8 and upcoming families.
The RAID containers are handled via the aacraidp0 bus. The physical buses are represented by the aacraidp? devices (beginning with
aacraidp1). These devices enable the SCSI pass-thru interface and allows devices connected to the card such as CD-ROMs to be available via
the CAM scsi(4) subsystem. Note that not all cards allow this interface to be enabled.
The /dev/aacraid? device nodes provide access to the management interface of the controller. One node exists per installed card. If the
kernel is compiled with the COMPAT_LINUX option, or the aacraid_linux.ko and linux.ko modules are loaded, the Linux-compatible ioctl(2)
interface for the management device will be enabled and will allow Linux-based management applications to control the card.
HARDWARE
Controllers supported by the aacraid driver include:
o Adaptec ASR-6405(T|E)
o Adaptec ASR-6445
o Adaptec ASR-6805(T|E|Q|TQ)
o Adaptec ASR-7085
o Adaptec ASR-7805(Q)
o Adaptec ASR-70165
o Adaptec ASR-71605(E|Q)
o Adaptec ASR-71685
o Adaptec ASR-72405
o Adaptec Series 8 cards
FILES
/dev/aacraid? aacraid management interface
DIAGNOSTICS
Compiling with AACRAID_DEBUG set to a number between 0 and 3 will enable increasingly verbose debug messages.
The adapter can send status and alert messages asynchronously to the driver. These messages are printed on the system console, and are also
queued for retrieval by a management application.

ahd -- Adaptec PCI/PCI-X Ultra320 SCSI host adapter driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device pci
device scbus
device ahd
To compile in debugging code:
options AHD_DEBUG
options AHD_DEBUG_OPTS=<bitmask of options>
options AHD_REG_PRETTY_PRINT
To configure one or more controllers to assume the target role:
options AHD_TMODE_ENABLE=<bitmask of units>
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
ahd_load="YES"
DESCRIPTION
This driver provides access to the SCSI bus(es) connected to Adaptec AIC79xx host adapter chips.
Driver features include support for narrow and wide busses, fast, ultra, ultra2, ultra160, and ultra320 synchronous transfers, packetized
transfers, tagged queueing, 512 SCB's, and target mode.
The AHD_DEBUG_OPTS option is used to control which diagnostic messages are printed to the console when AHD_DEBUG is enabled. Logically OR
the following bits together:
Value Function
0x0001 Show miscellaneous information
0x0002 Show sense data
0x0004 Show Serial EEPROM contents
0x0008 Show bus termination settings
0x0010 Show host memory usage
0x0020 Show SCSI protocol messages
0x0040 Show mode pointer of the chip register window
0x0080 Show selection timeouts
0x0100 Show FIFO usage messages
0x0200 Show Queue Full status
0x0400 Show SCB queue status
0x0800 Show inbound packet information
0x1000 Show S/G list information
0x2000 Enable extra diagnostic code in the firmware
The AHD_REG_PRETTY_PRINT option compiles in support for human-readable bit definitions for each register that is printed by the debugging
code. However, it also bloats the compiled size of the driver by approximately 215KB.
Individual controllers may be configured to operate in the target role through the AHD_TMODE_ENABLE configuration option. The value assigned
to this option should be a bitmap of all units where target mode is desired. For example, a value of 0x25 would enable target mode on units
0, 2, and 5. Note that target mode is only supported for ultra160 speeds and below.
Per target configuration performed in the SCSI-Select menu, accessible at boot, is honored by this driver. This includes synchronous/asyn-
chronous transfers, maximum synchronous negotiation rate, wide transfers, disconnection, and the host adapter's SCSI ID.
HARDWARE
The ahd driver supports the following:
o Adaptec AIC7901 host adapter chip
o Adaptec AIC7901A host adapter chip
o Adaptec AIC7902 host adapter chip
o Adaptec 29320 host adapter
o Adaptec 39320 host adapter
o Many motherboards with on-board SCSI support

The ahd driver first appeared in FreeBSD 4.7.
AUTHORS
The ahd driver, the AIC7xxx sequencer-code assembler, and the firmware running on the aic79xx chips was written by Justin T. Gibbs. This
manual page is based on the ahc(4) manual page.
BUGS
The current generation of 79xx chips do not support target mode in Ultra320 mode. Target mode in general has not been well tested in this
driver.
