Basically, we have two sources of income, corporate sponsorship and individual donations.

[oe] [PATCH] initscripts: don't background volatile creation
From: Chris Larson chris_lar...@mentor.com
This fix is courtesy Chris Hallinan. There is/can be assumptions made in
the volatiles file that they're processed in order (e.g. directory
created, then files within that directory), yet the script processes
them in parallel, backgrounding the operations. This is racy, and means
it's possible to end up with dependent files/dirs not created before the
bits that need them.
It's likely that this will have a performance impact, but I haven't
benchmarked it. Better that we behave correctly than quickly. We can
look back into improving the speed of this, without breaking
dependencies, in the future.

[oe] Packaging from devshell
Hi,
I use devshell for compiling by running a bitbake generated do_compile shell
script in work/ for my package, this helps me develop faster as I can skip
over parsing and other repetitive stages.
However I'm not able to do the same with do_package_write, as the shell
script for the same appears to have an empty function:
do_package_write() {
:
}
Could anyone suggest which script should I execute to package from
devshell?
Thanks,
Joel.

[oe] Bitbake master vs. openembedded classic
Hi, I'm still working with oe-dev on the KKK (klibc, kexec, kexecboot) which will be hopefully soon ready for oe-core. Trying a build from scratch after fresh pull breaks on gettext-native. Fresh oe.dev doesn't cope with bitbake master. I sent bitbake back to HEAD is now at ea0ca90 cooker.py: Drop duplicate parseCommandLine call and things works as before. Maybe next time I'll try to bisect pulling bitbake 1.13.1 Just FYI Andrea ___ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel

+Subject: [PATCH 2/4] DMAI: Auto-detect V4L2 display device node to open.
+
+Changes in display device node names in the kernel break DMAI.
+This autodetects the device node name to avoid such breakages in the future.
