mpt_soft_reset more than once. And to wait for MPT_DB_STATE_READY twice. I mean, this is crucial- give the IOC a chance to get ready. If mpt_reset is called to reinit things, and we succeed, make sure to re-enable interrupts. This is what has mostly led to system lockup after having to hard reset the chip. Also, if we think that interrupts aren't function in mpt_cam_timeout, for goodness sake, turn them on again. In read_cfg_header, return distinguishing errnos so the caller can decide what's an error. It's *not* an error to fail to read a RAID page from a non-RAID capable device like the FC929X. Some whitespace fixes (removing spaces from ends of lines).
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.
