Use the target offset rather than the target Id to reference the untagged SCB array. The offset and id are identical save in the twin channel case. This should correct several issues with the 2742T. Set the user and goal settings prior to setting the current settings. This allows the async update routine to filter out intermediate transfer negotiation updates that may be less than interesting. The Linux OSM uses this to reduce the amount of stuff printed to the console. aic7xxx.seq: Correct an issue with the aic7770 in twin channel mode. We could continually attempt to start a selection even though a selection was already occurring on one channel. This might have the side effect of hanging our selection or causing us to select the wrong device. While here, create a separate polling loop for when we have already started a selection. This should reduce the latency of our response to a (re)selection. The diffs look larger than they really are due to some code rearrangement to optimize out a jmp. aic7xxx_freebsd.c: Use the target offset rather than the target Id to reference the untagged SCB array. The offset and id are identical save in the twin channel case. This should correct several issues with the 2742T. aic7xxx_inline.h: Get back in sync with perforce revision ID. aic7xxx_pci.c: Identify adapters in ARO mode as such. Ensure that not only the subvendor ID is correct (9005) but also that the controller type field is valid before looking at other information in the subdevice id. Intel seems to have decided that their subdevice id of 8086 is more appropriate for some of their MBs with aic7xxx parts than Adaptec's sanctioned scheme. Add an exclusion entry for SISL (AAC on MB based adapters). Adapters in SISL mode are owned by the RAID controller, so even if a driver for the RAID controller is not present, it isn't safe for us to touch them.
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you have to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
