One team reverse engineers the hardware and creates a specifications document, the second team implements (from scratch or from unencumbered FOSS sources) the firmware that conforms to that specification. The two teams cannot talk about anything that deals with the hardware/firmware other than creating the specification document.

It is a weapon that can attack our nation's infrastructure much more effectively than a gun would. First, the name of the computer is the XO.

Hi, I received my OLPC through g1g1 a few days ago. I 'd like to contribute to gcc/library testing and workload characterization / profiling. I have a couple of questions regarding the gcc / glibc optimization effort: 1) I haven't found a default gcc in my xo system - if there is one, where is it installed ? I have built my own gcc from gcc4.3 svn with a similar configuration as the gnashdev project (http://wiki.gnashdev.org/wiki/index.php/Building_OLPC_Tools) Is the geode-patched gcc4.2.1 preferrable for integration with the XO? 2) My XO uses glibc2.6-4. I have reproduced the performance improvement from John Zulauf's optimizations (memcpy, memcmp, memset, strcmp, strcpy, strlen) against the local 2.6-4 implementation. The 2.6.5 glibc built on the gnashdev project includes these optimizations except from strcpy. Does anyone know why that is? Is the gnashdev build pushed for inclusion in upcoming stable systems? 3) Are there any important libraries or tools that still need to be analyzed/profiled or optimized for geode? FFTW, BLAS are mentioned on the optimization effort wiki/thread - are they being benchmarked by someone?

I thought I had a link to the working copy of strcpy() in assembler to anyone that wishes to improve the current optimization patch. There may be other routines worth optimizing. I limited my patch to what AMD had provided in their performance tests, as it was very convenient to start with known testing results. Most of what I did was just make the best perf-test code build as part of glibc. 3) Are there any important libraries or tools that still need to be analyzed/profiled or optimized for geode? FFTW, BLAS are mentioned on the optimization effort wiki/thread - are they being benchmarked by someone? Similarly, any important XO applications/system components that need to be benchmarked/ profiled with the default toolchains or with a newer toolchain? Any wiki links are appreciated. On my system I build most everything with the optimized toolchain. For a system like the XO, every cycle helps. I'd love to see more performance testing and improvement through the use of this geode-optimized toolchain, plus see the patches get migrated upstream. I can continue to keep the gnashdev wiki page updated with this info, or maybe it should live on the laptop.org wiki. - rob - ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

At http://wiki.gnashdev.org/wiki/index.php/Building_OLPC_Tools, you can get a binary tarball of gcc 4.3, plus rpms for the XO of glibc. Sorry it's not packaged as easily as being able to use yum, but at least this is an fully geode optimized toolchain. - rob - ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Musings on failing to update to joyride, and a few format questions
As I was watching my new B4 fail to update to the latest JR, I noticed a couple issues I'd like to take up. One: I noticed a few .wav files somewhere in the Comic builder activity? Are we planning on using .wav for anything? Or should this eventually be upgraded. Who *should* I bother about this? Two: there were some images somewhere in */share/activities/wdl/* that were named badly. They lined up like this: 10image 1image 2image ... So they don't sort properly. Can/should we change this, and should this rule be in the Sugar programing guidelines? Seth Woodworth ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Musings on failing to update to joyride, and a few format questions
I meant to say that we should instead name these: 01image 02image ... 10image Or for however many significant digits are required.
