-README - ocf-linux-20100530
-###########################
-
-This README provides instructions for getting ocf-linux compiled and
-operating in a generic linux environment. Other information on the project
-can be found at the home page:
-
- http://ocf-linux.sourceforge.net/
-
-Embedded systems and applications requiring userspace acceleration will need
-to patch the kernel source to get full OCF support. See "Adding OCF to
-linux source" below. Otherwise the "OCF Quickstart" that follows is the
-easiest way to get started.
-
-If your goal is to accelerate Openswan on Ubuntu or CentOS, you may find
-that the required binaries are already available on openswan.org:
-
- ftp://ftp.openswan.org/ocf/
- ftp://ftp.openswan.org/openswan/binaries/ubuntu/
-
-#####################################################
-OCF Quickstart for Ubuntu/Others (including Openswan)
-#####################################################
-
-This section provides instructions on how to quickly add kernel only support
-for OCF to a GNU/Linux system. It is only suitable for in-kernel use such as
-Openswan MAST/KLIPS.
-
-If the target is an embedded system, or, userspace acceleration of
-applications such as OpenVPN and OpenSSL, the section below titled
-"Adding OCF to linux source" is more appropriate.
-
-Before building kernel only support for OCF ensure that the appropriate
-linux-headers package is installed:
-
- cd ocf
- make ocf_modules
- sudo make ocf_install
- OCF_DIR=`pwd` # remember where OCF sources were built
-
-At this point the ocf, cryptosoft, ocfnull, hifn7751 and ocf-bench modules
-should have been built and installed. The OCF installation can be tested
-with the following commands:
-
- modprobe ocf
- modprobe cryptosoft
- modprobe ocf-bench
- dmesg | tail -5
-
-The final modprobe of ocf-bench will fail, this is intentional as ocf-bench
-is a short lived module that tests in-kernel performance of OCF. If
-everything worked correctly the "dmesg | tail -5" should include a line
-like:
-
- [ 583.128741] OCF: 45133 requests of 1488 bytes in 251 jiffies (535.122 Mbps)
-
-This shows the in-kernel performance of OCF using the cryptosoft driver.
-For addition driver load options, see "How to load the OCF modules" below.
-
-If the intention is to run an OCF accelerated Openswan (KLIPS/MAST) then use
-these steps to compile openswan downloaded from openswan.org (2.6.34 or later).
-
- tar xf openswan-2.6.34.tar.gz
- cd openswan-2.6.34
- make programs
- make KERNELSRC=/lib/modules/`uname -r`/build \
- KBUILD_EXTRA_SYMBOLS=$OCF_DIR/Module.symvers \
- MODULE_DEF_INCLUDE=`pwd`/packaging/ocf/config-all.hmodules \
- MODULE_DEFCONFIG=`pwd`/packaging/ocf/defconfig \
- module
- sudo make KERNELSRC=/lib/modules/`uname -r`/build \
- KBUILD_EXTRA_SYMBOLS=$OCF_DIR/Module.symvers \
- MODULE_DEF_INCLUDE=`pwd`/packaging/ocf/config-all.hmodules \
- MODULE_DEFCONFIG=`pwd`/packaging/ocf/defconfig \
- install minstall
-
-The rest of this document is only required for more complex build
-requirements.

-##########################
-Adding OCF to linux source
-##########################
-
-It is recommended that OCF be built as modules as it increases the
-flexibility and ease of debugging the system.
-
-Ensure that the system has /dev/crypto for userspace access to OCF:
-
- mknod /dev/crypto c 10 70
-
-Generate the kernel patches and apply the appropriate one.
-
- cd ocf
- make patch
-
-This will provide three files:
-
- linux-2.4.*-ocf.patch
- linux-2.6.*-ocf.patch
- ocf-linux-base.patch
-
-If either of the first two patches applies to the targets kernel, then one
-of the following as required:
-
- cd linux-2.X.Y; patch -p1 < linux-2.4.*-ocf.patch
- cd linux-2.6.Y; patch -p1 < linux-2.6.*-ocf.patch
-
-Otherwise, locate the appropriate kernel patch in the patches directory and
-apply that as well as the ocf-linux-base.patch using '-p1'.
-
-When using a linux-2.4 system on a non-x86 platform, the following may be
-required to build cryptosoft:
-
- cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
-
-When using cryptosoft, for simplicity, enable all the crypto support in the
-kernel except for the test driver. Likewise for the OCF options. Do not
-enable OCF crypto drivers for HW that is not present (for example the ixp4xx
-driver will not compile on non-Xscale systems).
-
-Make sure that cryptodev.h from the ocf directory is installed as
-crypto/cryptodev.h in an include directory that is used for building
-applications for the target platform. For example on a host system that
-might be:
-
- /usr/include/crypto/cryptodev.h
-
-Patch the openssl-0.9.8r code the openssl-0.9.8r.patch from the patches
-directory. There are many older patch versions in the patches directory
-if required.
-
-The openssl patches provide the following functionality:
-
- * enables --with-cryptodev for non BSD systems
- * adds -cpu option to openssl speed for calculating CPU load under linux
- * fixes null pointer in openssl speed multi thread output.
- * fixes test keys to work with linux crypto's more stringent key checking.
- * adds MD5/SHA acceleration (Ronen Shitrit), only enabled with the
- --with-cryptodev-digests option
- * fixes bug in engine code caching.
-
-Build the crypto-tools directory for the target to obtain a userspace
-testing tool call cryptotest.
-
-###########################
-How to load the OCF modules
-###########################
-
-First insert the base modules (cryptodev is optional, it is only used
-for userspace acceleration):
-
- modprobe ocf
- modprobe cryptodev
-
-Load the software OCF driver with:
-
- modprobe cryptosoft
-
-and zero or more of the OCF HW drivers with:
-
- modprobe safe
- modprobe hifn7751
- modprobe ixp4xx
- ...
-
-All the drivers take a debug option to enable verbose debug so that
-OCF operation may be observed via "dmesg" or the console. For debug
-load the modules as:
-
- modprobe ocf crypto_debug=1
- modprobe cryptodev cryptodev_debug=1
- modprobe cryptosoft swcr_debug=1
-
-More than one OCF crypto driver may be loaded but then there is no
-guarantee as to which will be used (other than a preference for HW
-drivers over SW drivers by most applications).
-
-It is also possible to enable debug at run time on linux-2.6 systems
-with the following:
-
- echo 1 > /sys/module/ocf/parameters/crypto_debug
- echo 1 > /sys/module/cryptodev/parameters/cryptodev_debug
- echo 1 > /sys/module/cryptosoft/parameters/swcr_debug
- echo 1 > /sys/module/hifn7751/parameters/hifn_debug
- echo 1 > /sys/module/safe/parameters/safe_debug
- echo 1 > /sys/module/ixp4xx/parameters/ixp_debug
- ...
-
-The ocf-bench driver accepts the following parameters:
-
- request_q_len - Maximum number of outstanding requests to OCF
- request_num - run for at least this many requests
- request_size - size of each request (multiple of 16 bytes recommended)
- request_batch - enable OCF request batching
- request_cbimm - enable OCF immediate callback on completion
-
-For example:
-
- modprobe ocf-bench request_size=1024 request_cbimm=0
-
-#######################
-Testing the OCF support
-#######################
-
-run "cryptotest", it should do a short test for a couple of
-des packets. If it does everything is working.
-
-If this works, then ssh will use the driver when invoked as:
-
- ssh -c 3des username@host
-
-to see for sure that it is operating, enable debug as defined above.
-
-To get a better idea of performance run:
-
- cryptotest 100 4096
-
-There are more options to cryptotest, see the help.
-
-It is also possible to use openssl to test the speed of the crypto
-drivers.
-
- openssl speed -evp des -engine cryptodev -elapsed
- openssl speed -evp des3 -engine cryptodev -elapsed
- openssl speed -evp aes128 -engine cryptodev -elapsed
-
-and multiple threads (10) with:
-
- openssl speed -evp des -engine cryptodev -elapsed -multi 10
- openssl speed -evp des3 -engine cryptodev -elapsed -multi 10
- openssl speed -evp aes128 -engine cryptodev -elapsed -multi 10
-
-for public key testing you can try:
-
- cryptokeytest
- openssl speed -engine cryptodev rsa -elapsed
- openssl speed -engine cryptodev dsa -elapsed

+* mvDramIfBasicInit - Basic initialization of DRAM interface
+*
+* DESCRIPTION:
+* The function will initialize the DRAM for basic usage. The function
+* will use the TWSI assembly API to extract DIMM parameters according
+* to which DRAM interface will be initialized.
+* The function referes to the following DRAM parameters:
+* 1) DIMM is registered or not.
+* 2) DIMM width detection.
+* 3) DIMM density.
+*
+* INPUT:
+* r3 - required size for initial DRAM.
+*
+* OUTPUT:
+* None.
+*
+* RETURN:
+* None.
+*
+* Note:
+* r4 holds I2C EEPROM address
+* r5 holds SDRAM register base address
+* r7 holds returned values
+* r8 holds SDRAM various configuration registers value.
+* r11 holds return function address.

+* mvDramIfBasicInit - Basic initialization of DRAM interface
+*
+* DESCRIPTION:
+* The function will initialize the DRAM for basic usage. The function
+* will use the TWSI assembly API to extract DIMM parameters according
+* to which DRAM interface will be initialized.
+* The function referes to the following DRAM parameters:
+* 1) DIMM is registered or not.
+* 2) DIMM width detection.
+* 3) DIMM density.
+*
+* INPUT:
+* r3 - required size for initial DRAM.
+*
+* OUTPUT:
+* None.
+*
+* RETURN:
+* None.
+*
+* Note:
+* r4 holds I2C EEPROM address
+* r5 holds SDRAM register base address
+* r7 holds returned values
+* r8 holds SDRAM various configuration registers value.
+* r11 holds return function address.
