respective CAM drivers. If you are using ATA device names in /etc/fstab or
other places, make sure to update them respectively (adX -> adaY,
acdX -> cdY, afdX -> daY, astX -> saY, where 'Y's are the sequential
numbers for each type in order of detection, unless configured otherwise

ataraid(4) functionality is now supported by the RAID GEOM class.
To use it you can load geom_raid kernel module and use graid(8) tool

Introduce the AHB glue for Atheros embedded systems. Right now it's
hard-coded for the AR9130 chip whose support isn't yet in this HAL;
it'll be added in a subsequent commit.
Kernel configuration files now need both 'ath' and 'ath_pci' devices; both
modules need to be loaded for the ath device to work.

still build it.
While it may be a perfect win in some scenarios, it still troubles users
(see PRs) in general cases. In addition we are still allocating resources
even if disabled by sysctl and still leak arp/nd6 entries in case of
interface destruction.

Octeon systems.
o) Make the Simple Executive's management port helper routines compile on
FreeBSD (namely by not doing math on void pointers.)
o) Add a cvmx_mgmt_port_sendm routine to the Simple Executive to send an mbuf
so there is only one copy in the transmit path, rather than having to first
copy the mbuf to an intermediate buffer and then copy that to the Simple
Executive's transmit ring.
o) Properly work out MII addresses of management ports on the Lanner MR-730.
XXX The MR-730 also needs some patches to the MII read/write routines, but
this is sufficient for now. Media detection will be fixed in the future
when I can spend more time reading the vendor-supplied patches.
running an o32 kernel safely, and would have to add interrupt disabling and
reenabling to a bunch of macros in the Simple Executive sources to support it.
The only reason one would run an o32 kernel on Octeon would be to run o32 world,
which is better worked towards by adding o32 binary compatibility to n64 kernels
along with, eventually, supporting multilib systems so o32 binaries can run
alongside n32 and n64 ones.

kernels with different worlds as part of make universe.
using miibus, since for some devices that use multiple addresses on the bus,
going through miibus may be unclear, and for devices that are not standard
MII PHYs, miibus may throw a fit, necessitating complicated interfaces to
fake the interface that it expects during probe/attach.
o) Make the mv88e61xx SMI interface in octe attach a PHY directly and fix some
mistakes in the code that resulted from trying too hard to present a nice
interface to miibus.
o) Add a PHY driver for the mv88e61xx. If attached (it is optional in kernel
compiles so the default behavior of having a dumb switch is preserved) it
will place the switch in a VLAN-tagging mode such that each physical port
has a VLAN associated with it and interfaces for the VLANs can be created to
address or bridge between them.
XXX It would be nice for this to be part of a single module including the
SMI interface, and for it to fit into a generic switch configuration
framework and for it to use DSA rather than VLANs, but this is a start
and gives some sense of the parameters of such frameworks that are not
currently present in FreeBSD. In lieu of a switch configuration
interface, per-port media status and VLAN settings are in a sysctl tree.
XXX There may be some minor nits remaining in the handling of broadcast,
multicast and unknown destination traffic. It would also be nice to go
through and replace the few remaining magic numbers with macros at some
point in the future.
XXX This has only been tested with the MV88E6161, but it should work with
minimal or no modification on related switches, so support for probing
them was included.

library:
o) Increase inline unit / large function growth limits for MIPS to accommodate
the needs of the Simple Executive, which uses a shocking amount of inlining.
o) Remove TARGET_OCTEON and use CPU_CNMIPS to do things required by cnMIPS and
the Octeon SoC.
o) Add OCTEON_VENDOR_LANNER to use Lanner's allocation of vendor-specific
board numbers, specifically to support the MR320.
o) Add OCTEON_BOARD_CAPK_0100ND to hard-wire configuration for the CAPK-0100nd,
which improperly uses an evaluation board's board number and breaks board
detection at runtime. This board is sold by Portwell as the CAM-0100.
o) Add support for the RTC available on some Octeon boards.
o) Add support for the Octeon PCI bus. Note that rman_[sg]et_virtual for IO
ports can not work unless building for n64.
o) Clean up the CompactFlash driver to use Simple Executive macros and
structures where possible (it would be advisable to use the Simple Executive
API to set the PIO mode, too, but that is not done presently.) Also use
structures from FreeBSD's ATA layer rather than structures copied from
Linux.
o) Print available Octeon SoC features on boot.
o) Add support for the Octeon timecounter.
o) Use the Simple Executive's routines rather than local copies for doing reads
and writes to 64-bit addresses and use its macros for various device
addresses rather than using local copies.
o) Rename octeon_board_real to octeon_is_simulation to reduce differences with
Cavium-provided code originally written for Linux. Also make it use the
same simplified test that the Simple Executive and Linux both use rather
than our complex one.
o) Add support for the Octeon CIU, which is the main interrupt unit, as a bus
to use normal interrupt allocation and setup routines.
o) Use the Simple Executive's bootmem facility to allocate physical memory for
the kernel, rather than assuming we know which addresses we can steal.
NB: This may reduce the amount of RAM the kernel reports you as having if
you are leaving large temporary allocations made by U-Boot allocated
when starting FreeBSD.
o) Add a port of the Cavium-provided Ethernet driver for Linux. This changes
Ethernet interface naming from rgmxN to octeN. The new driver has vast
improvements over the old one, both in performance and functionality, but
does still have some features which have not been ported entirely and there
may be unimplemented code that can be hit in everyday use. I will make
every effort to correct those as they are reported.
o) Support loading the kernel on non-contiguous cores.
o) Add very conservative support for harvesting randomness from the Octeon
random number device.
o) Turn SMP on by default.
o) Clean up the style of the Octeon kernel configurations a little and make
them compile with -march=octeon.
o) Add support for the Lanner MR320 and the CAPK-0100nd to the Simple
Executive.
o) Modify the Simple Executive to build on FreeBSD and to build without
executive-config.h or cvmx-config.h. In the future we may want to
revert part of these changes and supply executive-config.h and
cvmx-config.h and access to the options contained in those files via
kernel configuration files.
o) Modify the Simple Executive USB routines to support getting and setting
of the USB PID.

o) Set a local maxmem in sb_machdep.c to avoid trying to use pages over 2^64
under 32-bit ABIs. Our pmap needs corrected to use vm_paddr_t consistently,
then we can make vm_paddr_t 64-bit under 32-bit ABIs and add code in pmap
to limit phys_avail by the maximum PFN that a 32-bit PTE can hold.
that turned out to be unrelated, and the rest was, as pointed out by Neel,

Yes, this puts things in the wrong place, doesn't compile and is
woefully incomplete. However, it will allow us to more easily track
against the upstream sources without needing to import the entire

This port is based on FreeBSD 7.0 as of April 2007 and the pre-import
