Log:
MFC assembler version of match functions for amd64 and i386(*).
This gives approximately 15% improvement on compression case.
(*) i386 assembler version is enabled ONLY when MACHINE_CPU have
'i686' which is not default on FreeBSD/i386. One can specify
for instance CPUTYPE=pentium4 in /etc/make.conf to get this
feature.

Teach our GCC a little bit about mips64r2. This is enough to compile code
from the Cavium SDK which needs the assembler in mips64r2, which our BU
supports well enough for basic things.

+Readme for the Octeon Executive Library
+
+
+The Octeon Executive Library provides runtime support and hardware
+abstraction for the Octeon processor. The executive is composed of the
+libcvmx.a library as well as header files that provide
+functionality with inline functions.
+
+
+Usage:
+
+The libcvmx.a library is built for every application as part of the
+application build. (Please refer to the 'related pages' section of the
+HTML documentation for more information on the build system.)
+Applications using the executive should include the header files from
+$OCTEON_ROOT/target/include and link against the library that is built in
+the local obj directory. Each file using the executive
+should include the following two header files in order:
+
+#include "cvmx-config.h"
+#include "cvmx.h"
+
+The cvmx-config.h file contains configuration information for the
+executive and is generated by the cvmx-config script from an
+'executive-config.h' file. A sample version of this file is provided
+in the executive directory as 'executive-config.h.template'.
+
+Copy this file to 'executive-config.h' into the 'config' subdirectory
+of the application directory and customize as required by the application.
+Applications that don't use any simple executive functionality can omit
+the cvmx-config.h header file. Please refer to the examples for a
+demonstration of where to put the executive-config.h file and for an
+example of generated cvmx-config.h.
+
+For file specific information please see the documentation within the
+source files or the HTML documentation provided in docs/html/index.html.
+The HTML documentation is automatically generated by Doxygen from the
+source files.
+
+
+

New Revision: 206975
URL: http://svn.freebsd.org/changeset/base/206975
Log:
Move to using the SDK for more things. This is incomplete at present and only
boots multi-user with a single core. Something goes amiss after the second
core crashes. This also disables the RGMII driver entirely as it is going to
need substantially more work to move to the SDK.

New Revision: 206986
URL: http://svn.freebsd.org/changeset/base/206986
Log:
Move to using the SDK for UART stuff (not thrilled about using RBR for the base
or hard-coding 1024 as the offset, but that's what the Simple Executive does.
We can abstract this in a *reg.h in the near future at least.)

New Revision: 207018
URL: http://svn.freebsd.org/changeset/base/207018
Log:
o) Fix for compiles that don't use a config file. It may be that we should juse
use config files, but I'm still sort of blundering along with this.
o) Get rid of some nested externs and in one case reshuffle include order to avoid
the need for it.

New Revision: 207028
URL: http://svn.freebsd.org/changeset/base/207028
Log:
Merge from Octeon cnusers SDK 1.7.2.
XXX Some of these changes may be due to structural changes in binutils between
our version and the version that the SDK is based on; I have not yet done any
correctness checking, though I did take some small effort to minimize deltas.

Log:
o) Comment out RGMII driver.
o) Build a large amount of the Simple Executive code in for a mythical "octe"
driver.
XXX Not thrilled about including cvmx-bootmem.c. Looks like Linux probably
does this, too, but I'd be much happier providing an implementation of
the bootmem API in mips/cavium/ somewhere. But that's a concern for
once there's actually something functional.

+ * A few defines are used to control the operation of this driver:
+ * CONFIG_CAVIUM_RESERVE32
+ * This kernel config options controls the amount of memory configured
+ * in a wired TLB entry for all processes to share. If this is set, the
+ * driver will use this memory instead of kernel memory for pools. This
+ * allows 32bit userspace application to access the buffers, but also
+ * requires all received packets to be copied.
+ * CONFIG_CAVIUM_OCTEON_NUM_PACKET_BUFFERS
+ * This kernel config option allows the user to control the number of
+ * packet and work queue buffers allocated by the driver. If this is zero,
+ * the driver uses the default from below.
+ * USE_SKBUFFS_IN_HW
+ * Tells the driver to populate the packet buffers with kernel skbuffs.
+ * This allows the driver to receive packets without copying them. It also
+ * means that 32bit userspace can't access the packet buffers.
+ * USE_32BIT_SHARED
+ * This define tells the driver to allocate memory for buffers from the
+ * 32bit sahred region instead of the kernel memory space.
+ * USE_HW_TCPUDP_CHECKSUM
+ * Controls if the Octeon TCP/UDP checksum engine is used for packet
+ * output. If this is zero, the kernel will perform the checksum in
+ * software.
+ * USE_MULTICORE_RECEIVE
+ * Process receive interrupts on multiple cores. This spreads the network
+ * load across the first 8 processors. If ths is zero, only one core
+ * processes incomming packets.
+ * USE_ASYNC_IOBDMA
+ * Use asynchronous IO access to hardware. This uses Octeon's asynchronous
+ * IOBDMAs to issue IO accesses without stalling. Set this to zero
+ * to disable this. Note that IOBDMAs require CVMSEG.
+ * REUSE_SKBUFFS_WITHOUT_FREE
+ * Allows the TX path to free an skbuff into the FPA hardware pool. This
+ * can significantly improve performance for forwarding and bridging, but
+ * may be somewhat dangerous. Checks are made, but if any buffer is reused
+ * without the proper Linux cleanup, the networking stack may have very
+ * bizarre bugs.

New Revision: 207052
URL: http://svn.freebsd.org/changeset/base/207052
Log:
o) A cursory swing at mbuf usage in ethernet-rx.c.
o) Lock and link state changes.
o) Don't do math with void pointers.
o) Comment out interrupt-handling and tasklet code for the time being.

Log:
Correct locking, but make compile by commenting out nearly everything until I
add our MII infrastructure to this driver.

Comment out a bunch of stuff. Now, except for the procfs module, all of this
driver compiles and linking is only held back by trivial BSP differences in
FreeBSD and Linux.

Log:
o) Modify our Octeon BSP to provide octeon_bootinfo so that the Linux Ethernet
driver can access it.
o) Likewise, rename octeon_board_real to octeon_is_simulation.
o) Add the files entries to compile the Linux Ethernet driver. It panics due
to unimplemented code at startup now.

constructing it by hand. By using bootmem, we make it possible for the
SDK to use memory below where the kernel is loaded for its own bookkeeping
and such.

New Revision: 207104
URL: http://svn.freebsd.org/changeset/base/207104
Log:
o) Add a bus, ciu, which provides access to the Octeon interrupt controller to
devices that hang off of it and which passes everything else through to
nexus. It should likely be a nexus subclass instead of a bus in the
hierarchy, but this will do for now.
o) While here fix octe build.

New Revision: 207110
URL: http://svn.freebsd.org/changeset/base/207110
Log:
o) Turn some pr_err into printf. They should likely use log(), but that will
have to wait.
o) Convert SPI module to use proper interrupt allocation mechanism.
o) Use the FreeBSD spelling of unlikely in a few places in ethernet-tx.c; it
would be good for me to go back over my first few diffs that removed the
use of likely() and unlikely() and convert those to __predict_*().

Log:
o) Insert nops after disabling interrupts to avoid getting interrupted.
o) When changing wiring, in addition to maybe setting PG_W, maybe clear it.
o) Get rid of lmem locks, since this is all CPU local now, and remove pinning
and simply disable interrupts.
o) Likewise, don't possibly cause an IPI for lmem, since interrupts are
disabled at that point. Besides, they operate on inherently per-CPU VAs.

New Revision: 207157
URL: http://svn.freebsd.org/changeset/base/207157
Log:
o) Move more interface initialization into octe.c.
o) Add MII support.
o) Fix how octe_init() and octe_stop() are called within octe.c.
This is enough to get link status reported correctly (XXX only on interfaces
that are marked UP, though; an interface that's never marked UP is forced into
10M mode and is inoperable in the bootloader without a cold boot) and to
receive packets, although the content of those packets is just garbage.
