load f/w images > 0x7fff words), set ISP_FW_ATTR_SCCLUN. We explicitly don't believe we can find attributes if f/w is < 1.17.0, so we have to set SCCLUN for the 1.15.37 f/w we're using manually- otherwise every target will replicate itself across all 16 supported luns for non-SCCLUN f/w. Correctly set things up for 23XX and either fast posting or ZIO. The 23XX, it turns out, does not support RIO. If you put a non-zero value in xfwoptions, this will disable fast posting. If you put ICBXOPT_ZIO in xfwoptions, then the 23XX will do interrupt delays but post to the response queue- apparently QLogic *now* believes that reading multiple handles from registers is less of a win than writing (and delaying) multiple 64 byte responses to the response queue. At the end of taking a a good f/w crash dump, send the ISPASYNC_FW_DUMPED event to the outer layers (who can then do things like wake a user daemon to *fetch* the crash image, etc.).
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/doc/en_US.ISO8859-1/books/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 might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/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.
