  • issue 18 (Linux CESA support doesn't use DMA) commented on by dgehn...@gmail.com
    I have looked into this issue and have started implementing patches to the standard mv_cesa driver that will enable the TDMA engines to work with the CESA engines to off-load the processor. The problem I have run into is the documentation for the CESA/TDMA engines is missing details on how the engines hand-off between the TDMA engine DMA'ing into and out of the SRAM and running the CESA (authentication/encryption/cryptography) engine.

    I have the Marvell 88F180/88F619x/88F6281 Function Specification document and in Section 10.4.3.1 Attaching TDMA to Security Accelerator for Enhanced Software Flow, Figure 47, it shows the packet processing I am attempting to implement. However, it is missing information on how the TDMA engine hands off processing to the CESA engine, and then how the CESA tells the TDMA engine to continue.

    Does anyone have any extra documentation or application notes on the TDMA/CESA interaction?
  • issue 17 (Ethernet interface broken for Linux-2.6.35.5) commented on by gsiddy
    I have noticed that if i use the sheevaplug's code for openRD (ie) /arch/arm/mach-kirkwood/sheevaplug-setup.c by setting the archNumber to 2097 then one ethernet port(eth0) works. Then i copied the pci init function call from the openrd file into the above mentioned file and PCI-Express also seem to be working fine. But i defenitely require the other ethernet port as well. Tested until 2.6.37-RC1 with the same results.
  • issue 18 (Linux CESA support doesn't use DMA) reported by sascha-w...@silbe.org
    The mv_cesa driver doesn't use DMA, so performance is limited to 8MB/s (even less if the CPU is busy with other tasks). This makes quite a difference when (parts of) the hard disk is encrypted and/or when using IPSec.

    Much higher throughputs should be possible when using TDMA: reading input (<800MB/s), 20 cycles (16.6ns) per 16Byte block for encryption, writing output (<800MB/s) give a theoretical limit of 282MB/s. Even assuming 100% overhead this is more than one order of magnitude faster than what's currently achievable. It would also leave the CPU free for other tasks for longer periods of time.

    I have twice of OpenRD, one show the problem above with one of the two Ethernet interface working. The other, with the same code adaption didn't work. None of the two Ethernet interfaces start work. The log follows:

Marvell Technology Group Ltd. ("Marvell") is committed to respecting the privacy of the users of the www.Open-RD.org Internet site and its associated services (the "Open-RD Service") (collectively or individually "Users"). This statement governs information you provide to us or that we learn from your use of the Open-RD Service and tells you how we may collect, use, and in some instances share this information. Any information collected via other Marvel sites is handled in accordance with the privacy policy posted on such sites.

AWARENESS

What we collect

User Provided Information: You may provide to Marvell what is generally called "personally identifiable" information when you register or at other times (for example, in connection with correspondence between you and Marvell), such as name and e-mail address.

"Cookies" Information: When you visit the Open-RD Service, we may send one or more cookies - a small text file containing a string of alphanumeric characters - to your computer. Marvell uses both session cookies and persistent cookies. A persistent cookie remains after you close your browser and may be used by your browser on subsequent visits to the Open-RD Service. By using these cookies, we can "remember" what you have done on the Open-RD Service before and personalize our site for you. These persistent types of cookies can be removed, but each web browser is a little different, so please look through your browser "Help" file to learn the correct way to modify your cookies set-up. Please note that disabling cookies may prevent you from accessing some of the functionality and site offerings available via the Open-RD Service.

"Automatically Collected" Information: When you visit the Open-RD Service or open one of our HTML emails, we may record certain information from your web browser by using different types of technology. This "automatically collected" information may include your Internet Protocol address ("IP Address"), web browser type, the web pages or sites that you visit just before or just after the Open-RD Service, the pages you view on our site, and the dates and times that you visit.

How we use it

Marvell uses your information to better understand your needs and provide you with better service. We may use your email address, without further consent, for non-marketing or administrative purposes such as notifying you of major updates.

Marvell may use automatically collected information and cookies information to: (a) remember your information so that you will not have to re-enter it during your visit or the next time you visit the Open-RD Service; (b) provide custom, personalized content, and information; (c) monitor the effectiveness of our and the Open-RD community's efforts; and (d) monitor aggregate usage metrics such as total number of visitors and pages viewed.
