If the only change we have is a different config and this could be integrated into the Letux kernel tree, then that would be best in my opinion.
The Pyra kernel also has aufs patched in, which is needed for dbp to work. So it's slightly more than just a different defconfig.
Ok, looks good. It is no problem to merge these patches into the letux kernel and extend the defconfig. Where can I find them?
I also don't know if the sgx kernel module should be included, or that those should stay in their own package. It did need some extra kernel modifications to get it to compile last time( in the .12 kernel).
Well, we have an sgx kernel driver tree included but not configured or working:
http://git.goldelico.com/?p=gta04-kernel.git;a=shortlog;h=refs/heads/work/le...
(there is a similar branch for OMAP3 SGX which is working - but incompatible to above).
@aTc: I guess our Debian image creator can grab the source from the Letux Kernel and use the Pyra config for compilation, right?
The image creator builds everything from .deb packages, it doesn't do any compiling itself.
Could you please provide the config file so Nikolaus can include it? And let us know if there are any other patches that might be needed?
The only difference in the config file is that aufs has been enabled. Although in the recent version I compiled in a lot of modules to get the screen going as quickly as possible for a bootsplash and the hardware testing scripts.
I'm not sure which one aTc tried. If it was stable that rendered audio unusable, then it's fine. If it was testing / stable, then such critical things shouldn't happen :)
The audio problems I have are probably more to do with the hardware than the kernel. I'm not even sure audio ever worked at all on this prototype.
Maybe there a re no speakers installed.
Or did you hit the same issue as Michael recently?
aplayer expects a 4-channel audio file. The first two go to the headset and the other two to the handsfree speakers. If you supply a 2-channel audio file, it is not easy to get sound from speakers. The trick (for testing but not for daily use) is to use "play" (sox) to remix the channels.
