Remove sim queue freezes for resource shortages. I've had too many strange race conditions where I freeze on a resource shortage but never get unfrozen. Consolidate the remaining sim queue freeze condition (for loopdown) into an inline with debug messages that allows us to track problems at ISP_LOGDEBUG0 level easier. Change a bunch of debug messages about loop down/up conditions to ISP_LOGDEBUG0 level. Remove dead isp_relsim code. Change some internal flag stuff for efficiency. Complain vociferously if we try and use our FC scratch area while it's busy being used already (I mean, if we don't have solaris' ability to sleep as an interrupt thread which would allow us to just use a p/v semaphore, at least *say* when you've just borked yourself). Add infrastructure to allow overrides of hard loopid && initiator id from boot variables. Fix the usual quota of silly bugs: + 'ktmature' needs to be per-instance. Argh. + When entering isp_watchdog, set intsok to zero, preserving old value to restore later. It's not nice to try and sleep from splsoftclock. + Fix tick overflow buglet in checking timeout value. MFC after: 1 week
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 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.
