objects rather than synchronization objects. When a sync object is signaled, only the first thread waiting on it is woken up, and then it's automatically reset to the not-signaled state. When a notification object is signaled, all threads waiting on it will be woken up, and it remains in the signaled state until someone resets it manually. We want the latter behavior for NDIS events. - In kern_ndis.c:ndis_convert_res(), we have to create a temporary copy of the list returned by BUS_GET_RESOURCE_LIST(). When the PCI bus code probes resources for a given device, it enters them into a singly linked list, head first. The result is that traversing this list gives you the resources in reverse order. This means when we create the Windows resource list, it will be in reverse order too. Unfortunately, this can hose drivers for devices with multiple I/O ranges of the same type, like, say, two memory mapped I/O regions (one for registers, one to map the NVRAM/bootrom/whatever). Some drivers test the range size to figure out which region is which, but others just assume that the resources will be listed in ascending order from lowest numbered BAR to highest. Reversing the order means such drivers will choose the wrong resource as their I/O register range. Since we can't traverse the resource SLIST backwards, we have to make a temporary copy of the list in the right order and then build the Windows resource list from that. I suppose we could just fix the PCI bus code to use a TAILQ instead, but then I'd have to track down all the consumers of the BUS_GET_RESOURCE_LIST() and fix them too. |

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.
