luns) firmware for the Fibre Channel cards. We used to assume that if we didn't download firmware, we couldn't know what the firmware capability with respect to SCCLUNs is- and it's important because the lun field changes in the request queue entry based upon which firmware it is. At any rate, we *do* get back firmware attributes in mailbox register 6 when we do ABOUT FIRMWARE for all 2200/2300 cards- and for 2100 cards with at least 1.17.0 firmware. So- we now assume non-SCCLUN behaviour for 2100 cards with firmware < 1.17.0- and we check the firmware attributes for other cards (loaded firmware or not). This also allows us to get rid of the crappy test of isp_maxluns > 16- we simply can check firmware attributes for SCCLUN behaviour. This required an 'oops' fix to the outgoing mailbox count field for ABOUT FIRMWARE for FC cards. Also- while here, hardwire firmware revisions for loaded code for SBus cards. Apparently the 1.35 or 1.37 f/w we've been loading into isp1000 just doesn't report firmware revisions out to mailbox regs 1, 2 and 3 like everyone else. Grumble. Not that this fix hardly matters for FreeBSD. MFC after: 4 weeks
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.
