Re: /lib/lsb/init-functions vs. /etc/init.d/functions in init scripts?

Some of this is covered here: http://fedoraproject.org/wiki/FCNewInit/Initscripts One aspect of that is to switch from sourcing /etc/init.d/functions to sourcing /lib/lsb/init-functions. On the OLPC, we were concerned that the old initscript infrastructure had a considerable overhead. Would this change have a beneficial impact on speed? I used this benchmark to measure how slow a dummy initscript is: http://www.codewiz.org/pub/true.init Run it like this: time for i in `seq 1 10`; do ./true.init start; done On a B3/B4 laptop, executing 10 loops takes over 2 seconds.

My idea was to start by moving only the parts of code that LSB advertises from /etc/init.d/functions to /lib/lsb/init-functions. Would that make sense? Not unless lsb/init-functions moves to someplace that doesn't require the whole mess of the lsb stack; we don't want init scripts bringing in the entirety of openssl, X, cron, pax, shadow-utils, etc. Bill ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Duh! Reading the feature-list of the package would be a good thing I suppose. Thanks for the heads up on that. I already have scripts in pilgrim to do a sdk build which outputs a vmware image with vmware and VB meta files. Let's build on that and I can do sdk builds along with regular builds. Yay! J5 rocks. I just need to know what people think should be in a development image. BTW the build servers run as root and have qemu on them. Let's start with just the raw official images for now. I expect to have a few groups needing input into the SDK, including software and content developers (Mel can likely help with collecting input there). For right now we probably need to start with make something available and let people tell us what they are missing and/or tell us what they are doing to make the environment more useful for themselves. Over time we can flesh out what the developer/content-developer SDK overlay is composed of. Continuous-builds-are-good-for-iterative-development-ly yr's, Mike -- Mike C.

EXA performance
Aleph has recently been doing some performance measurements on the latest Xorg codebase, mostly concentrating on bench.py and other micro benchmarks. Performance of 16bpp VS 24bpp has been a hot topic recently. We know 24bpp to be much faster for some operations (my bench.py notably) and much slower for others (image puts), but it's not clear which one is the overall winner for our typical workload. Jim would like to see some numbers in order to make a decision. Aleph, could you publish the results of x11perf at least? The Cairo perfomance suite would be even more interesting to see. Chris also wanted to see timing of a real-world Sugar rendering... like switching between the 4 zoom levels. That may require some (perhaps trivial) Sugar surgery, so I'd leave it to one of the Python developers. Oprofile and/or sysprof output while executing all the above benchmarks would also provide invaluable information to find out *why* things are being slow. Aleph already has an environment in place with all the components rebuilt with debug symbols, so we can see the actual function calls in the output. Lastly, this thread may be generally interesting to whoever is seeking to improve EXA performance on the XO: http://thread.gmane.org/gmane.comp.freedesktop.xorg/20111/focus=20116 -- // Bernardo Innocenti \X/ http://www.codewiz.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
