freebsd kernel with SKQ
Go to file
Pyun YongHyeon 96ee09c546 o Sort includes and add <endian.h> to support endianness.
o Removed unneeded header files.
 o bus_dma(9) fix:
   - created parent tag with 1GB dma address limit with no
     alignment restrictions.
   - set 4096 alignment limit for Tx/Rx descriptor rings.
   - separate Rx buffer tag from Tx buffer tag such that Tx tag
     allows up-to 16 segments while Rx buffer tag only allows
     single segment.
   - it seems the controller has no alignment restrictions on Tx/Rx
     buffers. Remove ETHER_ALIGN alignment restriction in Tx/Rx
     buffers.
   - created a spare Rx dma map which would be used to cope with
     failure of loading a dma map.
   - make sure to load full Tx/Rx descriptor size for Tx/Rx
     descriptor dma maps, previously bfe(4) used to load single
     descriptor size for each descriptor rings. I have no idea how
     it could be run without problems.
   - don't blindly cast bus_addr_t type to 32bits in bfe_dma_map().
   - created bfe_dma_free() to free allocated dma memory/tags.
   - make sure to invoke bus_dmamap_sync(9) before/after processing
     descriptor rings/buffers. Because the hardware has severe dma
     address space limitation, bounce-buffers would be always used
     on systems with more than 1GB memory during
     descriptors/buffers access.
   - added Tx descriptor ring initialization function,
     bfe_list_tx_init().
   - moved producer/consumer index initialization to
     bfe_list_tx_init() and bfe_list_rx_init() from
     bfe_chip_reset().
   - added bfe_discard_buf() which will update loaded descriptors
     without unloading/reloading the dma map to speed up error
     recovery.
   - implemented Tx side bus_dmamap_load_mbuf_sg(9). The number of
     segments allowed was chosen to be 16 which should be enough for
     non-TSO capable hardwares. Setting SOF bit of Tx descriptor is
     done in the last to avoid potential race.
   - don't give up sending frames in bfe_start() until the hardware
     lacks free descriptors.
   - added XXX comment to second kick command and possible workaround.
   - implemented Rx side bus_dmamap_load_mbuf_sg(9).
   - removed bfe_dma_map_desc() as it's not needed anymore after
     the conversion to bus_dmamap_load_mbuf_sg(9).
   - added endianness support. With this change bfe(4) should work
     on any architectures that can create bounce buffers within 1GB
     address range.
   - add missing bus_dmamap_sync() in bfe_tx_eof()/bfe_rx_eof().
 o Use PCI_BAR instead of hardcoded value to set BARs.
   Simplified register access with bus_write_4(9)/bus_read_4(9) and
   removed bfe_btag, bfe_bhandle, bfe_vhandle in softc as it's not
   used anymore.
 o Reorder device detach logic such that bfe_detach() is also used
   for handling driver attach failure case.
 o Remove unnecessary KASSERT in bfe_detach().
 o Remove bfe_rx_cnt, bfe_up, bfe_vpd_prodname, bfe_vpd_readonly in
   softc.  It's not used at all.
 o Remove BFE_RX_RING_SIZE/BFE_RX_RING_SIZE/BFE_LINK_DOWN.

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.
