series, the 8139C+ has a descriptor-based DMA mechanism, and its performance is actually pretty respectable. Note: the 8139D chip does not support C+ mode. Only the 8139C+ and 8169 gigE chips support C+ mode. Supported features: - RX and TX checksum offload - hardware VLAN tag insertion/extraction - TX interrupt moderation using the 8139's on-board timer Everything should be properly busdma'ed and endian-independent, so things should work ok on non-x86 platforms. Unfortunately, my call for testers on this code was met with deafening silence, and I don't have access to any non-x86 FreeBSD boxes at the moment, so this is speculation. The device detection code has been cleaned up a little as well (thanks to Michal Mertl) for the patches. There are also updates to the rl(4) man page (which I accidentally checked in before when I updated the dc(4) man page. Oops.) Todo: finish support for the 8169 gigabit ethernet chip. This mainly requires writing an rlgphy driver to handle the 8169's built-in PHY. This will have to wait until I actually get my hands on an 8169 card for testing though. (I still can't find a source for one in the U.S. Suggestions/pointers welcome.) |

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.
