cards that should be handled by the mfi(4) driver. The root of the problem is that the mpt(4) driver was masking off the bottom bit of the PCI device ID when deciding which cards to attach to. It appears that a number of the mpt(4) Fibre Channel cards had a LAN variant whose PCI device ID was just one bit off from the FC card's device ID. The FC cards were even and the LAN cards were odd. The problem was that this pattern wasn't carried over on the SAS and parallel SCSI mpt(4) cards. Luckily the SAS and parallel SCSI PCI device IDs were either even numbers, or they would get masked to a supported adjacent PCI device ID, and everything worked well. Now LSI is using some of the odd-numbered PCI device IDs between the 3Gb SAS device IDs for their new MegaRAID cards. This is causing the mpt(4) driver to attach to the RAID cards instead of the mfi(4) driver. The solution is to stop masking off the bottom bit of the device ID, and explicitly list the PCI device IDs of all supported cards. This change should be a no-op for mpt(4) hardware. The only intended functional change is that for the 929X, the is_fc variable gets set. It wasn't being set previously, but needs to be because the 929X is a Fibre Channel card.

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 ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. 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.
