o Attempt to disable the slot when we detect that there are problems with it in our ISR. This should make polling mode work better for more cards, but more work may be needed. This "disabling" sets the card interrupt register to 0. This worked for me for lots of tests in polling mode. o Now that I've found datasheets, fix a boatload of magic numbers in the source to make it easier to understand. o Use a table of names rather than a big case statement. o Cull a few of the "unused" controller types that we map to other times that were a vestiage of PAO code that we never merged in the same way. o Enforce legal IRQs. You are no longer allowed to try to use IRQs that will fail on all known ISA/PCI <-> PCMCIA bridges. The bridges do not have pins for these illegal interrupts, and all of them are listed as reserved and/or illegeal in the datasheets depending on which one you look at. o Add comments about how IBM-AT based computers and NEC PC-98 based computers map these interrupts and which ones are valid. o Always clear the bit that steers the management interrupt either to the value listed in the PCIC_STAT_INT register. I've seen this bit get set on suspend/resume and after windows boot, and it does't hurt to clear it. NOTE: this might mean we can share this interrupt in the future.
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.
