4) The cardbus CIS code treats the CIS_PTR as a mapping register if it is mentioned in the CIS. I don't have a spec handy to understand why the CIS_PTR is mentioned in the CIS, but allocating a memory range for it is certainly bogus. My patch ignores bar #6 to prevent the mapping. [The pccard spec says that BAR 0 and 7 (-1 and 6 in thic case since we did a minus one) is "reserved". The off by 1 error has been fixed. also bar=5 is invalid for IO maps, so we check it.] 5) The CIS code allocated duplicate resources to those already found by cardbus_add_resources(). The fix is to pass in the bar computed from the CIS instead of the particular resource ID for that bar, so bus_generic_alloc_resource succeeds in finding the old resource. [fixed, also removed superfluous (and incorrect) writing back to the PCI config space.] 7) The CIS code seems to use the wrong bit to determine rather a particular register mapping is for I/O or memory space. From looking at the two cards I have, it seems TPL_BAR_REG_AS should be 0x10 instead of 0x08. Otherwise, all registers that should be I/O mapped gain a second mapping in memory space. [Oops, the spec does say 0x10..., fixed] Submitted by: Justin Gibbs |

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.
