- Remove double buffering interrupt and isochronous traffic via the transaction translator. It can be avoided because the DWC OTG will always delay the start split transactions for interrupt and isochronous traffic, but will not delay the complete split transactions, if we set the odd frame bit correctly. - Need to check the transfer cache field in the device done function to be sure all allocated channels are freed and not the transfer first one. This seems to resolve the control endpoint transfer type quirk which is now removed. - Make sure any received data upon TX is dumped else RX path will stop. - Transmit isochronous data before receiving isochronous data as a means to optimise the TT schedule. - Implement a simple TT bandwidth scheduler. - Cleanup use of old "td->error" variable. - On interrupt IN traffic via the transaction translator we simply ignore missed transfer opportunities and silently retry the transaction upon next available time slot.

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 ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. 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.
