Re: [maemo-developers] automatic byte order check
Hello, The (linux) kernel has endianess-aware integer types (__be_u16 or something similar) which allow the access to be checked for endianess problems (basically reading an endianess-annotated type into a non-endianess-specified (ie native endianess) type must go through a byte order macro). You have to annotate by hand all shared structures with these types. In your case, this would be all network-shared structures. I'm not sure the compiler does the check though, it may be an external tool. It could be however very interesting to generalize this outside of the kernel.

The Clock application has the ability to set alarms that wake the device, so it must be possible. From the reverse-engineering department, have you straced this Clock application to have a look at what it does (I don't have a N770, so this is a very wild guess) ? Either it's doing the alarm setting directly (possibly through the kernel), and then you'll precisely see what needs be done, or it does it via some IPC to another app (which you'll need to identify and strace accordingly). This may be faster than waiting for a response :) JB -- Jean-Baptiste Note +33 (0)6 83 03 42 38 [EMAIL PROTECTED] signature.asc Description: PGP signature ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
Re: [maemo-developers] custom gstreamer plugins
Hello, To be a bit more precise, a plugin won't load if it has unresolved symbols/libraries at load time. This is something that bites badly when developping custom plugins. You may know which libraries are needed (and the missing ones should be clearly outlined) by running ldd on the .so file of your plugin. For instance on an (x86) debian system: ldd /usr/lib/gstreamer-0.10/libgstmpeg2dec.so linux-gate.so.1 = (0xe000) libgstreamer-0.10.so.0 = /usr/lib/libgstreamer-0.10.so.0 (0xb7e9b000) libgobject-2.0.so.0 = /usr/lib/libgobject-2.0.so.0 (0xb7e6) libgmodule-2.0.so.0 = /usr/lib/libgmodule-2.0.so.0 (0xb7e5c000) libdl.so.2 = /lib/tls/libdl.so.2 (0xb7e3d000) libgthread-2.0.so.0 = /usr/lib/libgthread-2.0.so.0 (0xb7e39000) libxml2.so.2 = /usr/lib/libxml2.so.2 (0xb7d2) libz.so.1 = /usr/lib/libz.so.1 (0xb7d0b000) libm.so.6 = /lib/tls/libm.so.6 (0xb7ce5000) libglib-2.0.so.0 = /usr/lib/libglib-2.0.so.0 (0xb7c5d000) libmpeg2.so.0 = /usr/lib/libmpeg2.so.0 (0xb7c3f000) libpthread.so.0 = /lib/tls/libpthread.so.0 (0xb7c2d000) libc.so.6 = /lib/tls/libc.so.6 (0xb7af5000) /lib/ld-linux.so.2 (0x8000) Now, ldd must be available on the N770, of course :) JB signature.asc Description: PGP signature ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
Re: [maemo-developers] Nokia 770 CPU clock frequency question
Hi, You definitely want to have a look in the maemo kernel sources in: kernel-source-2.6.12.3-2.6.12.3/arch/arm/mach-omap/clock.h and more importantly for starters: kernel-source-2.6.12.3-2.6.12.3/arch/arm/mach-omap/clock.h I think that a proper reading of the frequency would poke the appropriate registers.

Re: [maemo-developers] WLAN GPL driver announcement
Hi Greg, Now that the softmac layer is in the mainline kernel tree, is there a simple patch that provides this driver? Why is it not also in the mainline kernel tree now? Until now I used the madwifi net80211 stack. This what I offer for download, and what I get feedback on from people using the driver. Pete was alone porting the driver to the in-kernel softmac, much to my shame. The port does not seem complete at the moment - it doesn't seem to work right with Pete's devices at least, and I have not tested it on mine. My plan to help Pete for the in-tree softmac port (there are protocol subtleties which are not documented and cause problems), and then propose for mainline inclusion under Pete's guidance. But i'm not fast. Jean-Baptiste ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
