power x 0. pccardc power x 0 used to disable the slot. But a suspend/resume would reactivate the pccard. It no longer does that. Now the disabling of the slot is sticy until it is reset with power x 1 or the card is ejected. This seems closer to correct behavior to me. o Process all card state changes the same using pccard_do_stat_change(). o Cleanup disabling the card so that we can preserve the state after the change. Basically, don't set it to empty as often as we do. o On suspend, the new state is "empty" and the laststate is "suspend" o Document state machine with a diagram of states and edges. The edges are labeld to tell the reader what event causes the external state changes. o "machdep.pccard.pcic_resume_reset" may be obsolete now. We always call the bridge driver's resume method on resume now. Otherwise cards won't automatically show up. If it needs to stay, I'll add it back.
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.
