    opengl es 2.0 at 3000 polys too slow?

    If you don't mind your code being open, I'd advise to learn git and use github, you'll share your code easily and you'll gain many many benefits for yourself.

    GCC runtime profiling optimization

    Wow, if you got 10-20% gain, I must say it is definitely worth it! It wasn't my experience on my tests, so it definitely depends on the code base

    GCC runtime profiling optimization

    Profile-guided optimization (PGO) is quite often a pain in the ass (PITA :D ). You have to create a profile that covers all important code paths, the instrumented exe is sloooooooooow, and it makes your build process more complicated with an iteration. Gains are not interesting when the...

    cachegrind

    Salut le belge, Cachegrind will only simulate a cache in its VM and it is quite slow. Maybe you can try using my perf build to monitor cache misses for real : It's accurate and unintrusive. Do something like: "LD_LIBRARY_PATH=. ./perf record -e L1-dcache-misses your_program" then...

    .next development

    What sub-repositories should be updated and on what branches to help .next? Edit: I found oebb.sh update to fast forward all repositories in one shot Bonus question, what is the policy if we want recipes that exist only in git://git.openembedded.org/openembedded (ie fluidsynth)? Migrate...

    Profiling

    Ok, I have a perf binary from .next openembedded that works with Zaxxon too. If someone is interested, I could publish it but how? This command-line tool makes no sense as a PND, does it?

    My mistake, I was confused by gitweb. I'm trying pandora-3.2, thanks.

    Profiling

    Yep, but does it make any sense? And will it work? :)

    Profiling

    Dang I can't find the /tools directory where perf source are supposed to live in any branch of git://git.openpandora.org/pandora-kernel.git Can somebody enlighten me?

    Profiling

    Ok,thanks. I tried "opkg install oprofile" and "opkg install perf" as root without success, so I'll try to build these from source. (Yep CodeAnalyst and vTune are respectively AMD and Intel sampling profilers)

    Profiling

    Hello guys, what good profilers are available for the pandora? Something like Linux perf, CodeAnalyst, vTune. I'd like to avoid intrusive stuff like gprof if possible. Cheers, Bertrand

    Pandora Can you program the Pandora hardware directly?

    Basically, the answer implied is "If you're asking, you probably shouldn't try" :)

    Patch for making the toolchain compilable on Fedora 13 x64

    Applies on openembedded.git 82c72465958e11e4e97a55ba22f90afd01aa785e Basically it just updates GNU m4 to work around a compile bug. (It is tgz'ed because the forum doesn't want me to attach a .patch) By the way, what is the official method to submit patches? Cheers, hope I will have time...

    Angstrom packages and using opkg?

    By the way, what is the official stance about opkg upgrading regularly? Recommended? Not recommended?

    Help! Wi Fi dead

    Ok, I tried lots of stuff to make it work without touching my router. Then, out of despair, I changed from channel 5 to 7. It now works like a charm :) (Black Magic Inside, both channels were unused by other wireless equipment) Edit: It's gone again... sigh... Edit 2: The Beta...

    Help! Wi Fi dead

    Hey guys, I just received my device, and I can't get Wifi working at home (and I could with two PCs and a PSP), DHCP or static, HF4 reinstalled or not... I even tried to ditch NetworkManager and go through wpa_supplicant. No suspect stuff in dmesg output. I even had a ping on my router and...
