+README - ocf-linux-20100325
+---------------------------
+
+This README provides instructions for getting ocf-linux compiled and
+operating in a generic linux environment. For other information you
+might like to visit the home page for this project:
+
+ http://ocf-linux.sourceforge.net/
+
+Adding OCF to linux
+-------------------
+
+ Not much in this file for now, just some notes. I usually build
+ the ocf support as modules but it can be built into the kernel as
+ well. To use it:
+
+ * mknod /dev/crypto c 10 70
+
+ * to add OCF to your kernel source, you have two options. Apply
+ the kernel specific patch:
+
+ cd linux-2.4*; gunzip < ocf-linux-24-XXXXXXXX.patch.gz | patch -p1
+ cd linux-2.6*; gunzip < ocf-linux-26-XXXXXXXX.patch.gz | patch -p1
+
+ if you do one of the above, then you can proceed to the next step,
+ or you can do the above process by hand with using the patches against
+ linux-2.4.35 and 2.6.33 to include the ocf code under crypto/ocf.
+ Here's how to add it:
+
+ for 2.4.35 (and later)
+
+ cd linux-2.4.35/crypto
+ tar xvzf ocf-linux.tar.gz
+ cd ..
+ patch -p1 < crypto/ocf/patches/linux-2.4.35-ocf.patch
+
+ for 2.6.23 (and later), find the kernel patch specific (or nearest)
+ to your kernel versions and then:
+
+ cd linux-2.6.NN/crypto
+ tar xvzf ocf-linux.tar.gz
+ cd ..
+ patch -p1 < crypto/ocf/patches/linux-2.6.NN-ocf.patch
+
+ It should be easy to take this patch and apply it to other more
+ recent versions of the kernels. The same patches should also work
+ relatively easily on kernels as old as 2.6.11 and 2.4.18.
+
+ * under 2.4 if you are on a non-x86 platform, you may need to:
+
+ cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
+
+ so that you can build the kernel crypto support needed for the cryptosoft
+ driver.
+
+ * For simplicity you should enable all the crypto support in your kernel
+ except for the test driver. Likewise for the OCF options. Do not
+ enable OCF crypto drivers for HW that you do not have (for example
+ ixp4xx will not compile on non-Xscale systems).
+
+ * make sure that cryptodev.h (from ocf-linux.tar.gz) is installed as
+ crypto/cryptodev.h in an include directory that is used for building
+ applications for your platform. For example on a host system that
+ might be:
+
+ /usr/include/crypto/cryptodev.h
+
+ * patch your openssl-0.9.8n code with the openssl-0.9.8n.patch.
+ (NOTE: there is no longer a need to patch ssh). The patch is against:
+ openssl-0_9_8e
+
+ If you need a patch for an older version of openssl, you should look
+ to older OCF releases. This patch is unlikely to work on older
+ openssl versions.
+
+ openssl-0.9.8n.patch
+ - 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 crypto-tools-XXXXXXXX.tar.gz if you want to try some of the BSD
+ tools for testing OCF (ie., cryptotest).
+
+How to load the OCF drivers
+---------------------------
+
+ First insert the base modules:
+
+ insmod ocf
+ insmod cryptodev
+
+ You can then install the software OCF driver with:
+
+ insmod cryptosoft
+
+ and one or more of the OCF HW drivers with:
+
+ insmod safe
+ insmod hifn7751
+ insmod ixp4xx
+ ...
+
+ all the drivers take a debug option to enable verbose debug so that
+ you can see what is going on. For debug you load them as:
+
+ insmod ocf crypto_debug=1
+ insmod cryptodev cryptodev_debug=1
+ insmod cryptosoft swcr_debug=1
+
+ You may load more than one OCF crypto driver but then there is no guarantee
+ as to which will be used.
+
+ You can also enable debug at run time on 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
+ ...
+
+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

+ * This is the control structure used to pass commands to hifn_encrypt().
+ *
+ * flags
+ * -----
+ * Flags is the bitwise "or" values for command configuration. A single
+ * encrypt direction needs to be set:
+ *
+ * HIFN_ENCODE or HIFN_DECODE
+ *
+ * To use cryptography, a single crypto algorithm must be included:
+ *
+ * HIFN_CRYPT_3DES or HIFN_CRYPT_DES
+ *
+ * To use authentication is used, a single MAC algorithm must be included:
+ *
+ * HIFN_MAC_MD5 or HIFN_MAC_SHA1
+ *
+ * By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
+ * If the value below is set, hash values are truncated or assumed
+ * truncated to 12 bytes:
+ *
+ * HIFN_MAC_TRUNC
+ *
+ * Keys for encryption and authentication can be sent as part of a command,
+ * or the last key value used with a particular session can be retrieved
+ * and used again if either of these flags are not specified.
+ *
+ * HIFN_CRYPT_NEW_KEY, HIFN_MAC_NEW_KEY
+ *
+ * session_num
+ * -----------
+ * A number between 0 and 2048 (for DRAM models) or a number between
+ * 0 and 768 (for SRAM models). Those who don't want to use session
+ * numbers should leave value at zero and send a new crypt key and/or
+ * new MAC key on every command. If you use session numbers and
+ * don't send a key with a command, the last key sent for that same
+ * session number will be used.
+ *
+ * Warning: Using session numbers and multiboard at the same time
+ * is currently broken.
+ *
+ * mbuf
+ * ----
+ * Either fill in the mbuf pointer and npa=0 or
+ * fill packp[] and packl[] and set npa to > 0
+ *
+ * mac_header_skip
+ * ---------------
+ * The number of bytes of the source_buf that are skipped over before
+ * authentication begins. This must be a number between 0 and 2^16-1
+ * and can be used by IPsec implementers to skip over IP headers.
+ * *** Value ignored if authentication not used ***
+ *
+ * crypt_header_skip
+ * -----------------
+ * The number of bytes of the source_buf that are skipped over before
+ * the cryptographic operation begins. This must be a number between 0
+ * and 2^16-1. For IPsec, this number will always be 8 bytes larger
+ * than the auth_header_skip (to skip over the ESP header).
+ * *** Value ignored if cryptography not used ***

+*
+* DESCRIPTION:
+* This function implements the full DRAM detection and timing
+* configuration for best system performance.
+* Since this routine runs from a ROM device (Boot Flash), its stack
+* resides on RAM, that might be the system DRAM. Changing DRAM
+* configuration values while keeping vital data in DRAM is risky. That
+* is why the function does not preform the configuration setting but
+* prepare those in predefined 32bit registers (in this case IDMA
+* registers are used) for other routine to perform the settings.
+* The function will call for board DRAM SPD information for each DRAM
+* chip select. The function will then analyze those SPD parameters of
+* all DRAM banks in order to decide on DRAM configuration compatible
+* for all DRAM banks.
+* The function will set the CPU DRAM address decode registers.
+* Note: This routine prepares values that will overide configuration of
+* mvDramBasicAsmInit().
+*
+* INPUT:
+* forcedCl - Forced CAL Latency. If equal to zero, do not force.
+*
+* OUTPUT:
+* None.

+* mvDramIfDetect - Prepare DRAM interface configuration values.
+*
+* DESCRIPTION:
+* This function implements the full DRAM detection and timing
+* configuration for best system performance.
+* Since this routine runs from a ROM device (Boot Flash), its stack
+* resides on RAM, that might be the system DRAM. Changing DRAM
+* configuration values while keeping vital data in DRAM is risky. That
+* is why the function does not preform the configuration setting but
+* prepare those in predefined 32bit registers (in this case IDMA
+* registers are used) for other routine to perform the settings.
+* The function will call for board DRAM SPD information for each DRAM
+* chip select. The function will then analyze those SPD parameters of
+* all DRAM banks in order to decide on DRAM configuration compatible
+* for all DRAM banks.
+* The function will set the CPU DRAM address decode registers.
+* Note: This routine prepares values that will overide configuration of
+* mvDramBasicAsmInit().
+*
+* INPUT:
+* forcedCl - Forced CAL Latency. If equal to zero, do not force.
+* eccDisable - Force down the ECC.
+*
+* OUTPUT:
+* None.
+*
+* RETURN:
+* None.

+* mvEth.c - Marvell's Gigabit Ethernet controller low level driver
+*
+* DESCRIPTION:
+* This file introduce OS independent APIs to Marvell's Gigabit Ethernet
+* controller. This Gigabit Ethernet Controller driver API controls
+* 1) Operations (i.e. port Init, Finish, Up, Down, PhyReset etc').
+* 2) Data flow (i.e. port Send, Receive etc').
+* 3) MAC Filtering functions (ethSetMcastAddr, ethSetRxFilterMode, etc.)
+* 4) MIB counters support (ethReadMibCounter)
+* 5) Debug functions (ethPortRegs, ethPortCounters, ethPortQueues, etc.)
+* Each Gigabit Ethernet port is controlled via ETH_PORT_CTRL struct.
+* This struct includes configuration information as well as driver
+* internal data needed for its operations.
+*
+* Supported Features:
+* - OS independent. All required OS services are implemented via external
+* OS dependent components (like osLayer or ethOsg)
+* - The user is free from Rx/Tx queue managing.
+* - Simple Gigabit Ethernet port operation API.
+* - Simple Gigabit Ethernet port data flow API.
+* - Data flow and operation API support per queue functionality.
+* - Support cached descriptors for better performance.
+* - PHY access and control API.
+* - Port Configuration API.
+* - Full control over Special and Other Multicast MAC tables.

+*
+* Assumptions :
+* Bar0 is always internal registers bar
+* Bar1 is always the DRAM bar
+* Bar2 is always the Device bar
+*
+* 1) Sets the Internal registers bar base by obtaining the base from
+* the CPU Interface
+* 2) Sets the DRAM bar base and size by getting the base and size from
+* the CPU Interface when the size is the sum of all enabled DRAM
+* chip selects and the base is the base of CS0 .
+* 3) Sets the Device bar base and size by getting these values from the
+* CPU Interface when the base is the base of the lowest base of the
+* Device chip selects, and the
+*
+*
+* INPUT:
+*
+* pexIf - PEX interface number.
+*
+*
+* OUTPUT:
+* None.

+ * ---------------------------------------------------------------------------
+ *
+ * NOTES:
+ *
+ * The Freescale SEC (also known as 'talitos') resides on the
+ * internal bus, and runs asynchronous to the processor core. It has
+ * a wide gamut of cryptographic acceleration features, including single-
+ * pass IPsec (also known as algorithm chaining). To properly utilize
+ * all of the SEC's performance enhancing features, further reworking
+ * of higher level code (framework, applications) will be necessary.
+ *
+ * The following table shows which SEC version is present in which devices:
+ *
+ * Devices SEC version
+ *
+ * 8272, 8248 SEC 1.0
+ * 885, 875 SEC 1.2
+ * 8555E, 8541E SEC 2.0
+ * 8349E SEC 2.01
+ * 8548E SEC 2.1
+ *
+ * The following table shows the features offered by each SEC version:
+ *
+ * Max. chan-
+ * version Bus I/F Clock nels DEU AESU AFEU MDEU PKEU RNG KEU
+ *
+ * SEC 1.0 internal 64b 100MHz 4 1 1 1 1 1 1 0
+ * SEC 1.2 internal 32b 66MHz 1 1 1 0 1 0 0 0
+ * SEC 2.0 internal 64b 166MHz 4 1 1 1 1 1 1 0
+ * SEC 2.01 internal 64b 166MHz 4 1 1 1 1 1 1 0
+ * SEC 2.1 internal 64b 333MHz 4 1 1 1 1 1 1 1
+ *
+ * Each execution unit in the SEC has two modes of execution; channel and
+ * slave/debug. This driver employs the channel infrastructure in the
+ * device for convenience. Only the RNG is directly accessed due to the
+ * convenience of its random fifo pool. The relationship between the
+ * channels and execution units is depicted in the following diagram:
+ *
+ * ------- ------------
+ * ---| ch0 |---| |
+ * ------- | |
+ * | |------+-------+-------+-------+------------
+ * ------- | | | | | | |
+ * ---| ch1 |---| | | | | | |
+ * ------- | | ------ ------ ------ ------ ------
+ * |controller| |DEU | |AESU| |MDEU| |PKEU| ... |RNG |
+ * ------- | | ------ ------ ------ ------ ------
+ * ---| ch2 |---| | | | | | |
+ * ------- | | | | | | |
+ * | |------+-------+-------+-------+------------
+ * ------- | |
+ * ---| ch3 |---| |
+ * ------- ------------
+ *
+ * Channel ch0 may drive an aes operation to the aes unit (AESU),
+ * and, at the same time, ch1 may drive a message digest operation
+ * to the mdeu. Each channel has an input descriptor FIFO, and the
+ * FIFO can contain, e.g. on the 8541E, up to 24 entries, before a
+ * a buffer overrun error is triggered. The controller is responsible
+ * for fetching the data from descriptor pointers, and passing the
+ * data to the appropriate EUs. The controller also writes the
+ * cryptographic operation's result to memory. The SEC notifies
+ * completion by triggering an interrupt and/or setting the 1st byte
+ * of the hdr field to 0xff.
+ *
+ * TODO:
+ * o support more algorithms
+ * o support more versions of the SEC
+ * o add support for linux 2.4
+ * o scatter-gather (sg) support
+ * o add support for public key ops (PKEU)
+ * o add statistics
