- Fix bfe_encap so that it will pass the address of the mbuf back up to its caller if/when it modifies it, as it does when doing a m_defrag on a mbuf chain. - Make sure to unload the dmamap for ALL fragments of a packet, not just the first - Use BUS_DMA_NOWAIT for all bus_dmamap_load calls so that the allocation of the map is not delayed - this driver is not set up to handle such delays. - Reduce the number of RX and TX buffers bfe uses so that it does not use more bounce buffers than busdma is willing to allow it to use With these changes, the driver now works properly for a user with a 2GB system, and it also works on my system when the acceptable address range is lowered to 128MB. Previously, both of these setups would act up after a few minutes of activity.
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.
