From 77988c32f1c9b3eb9248ac6eb296fb8f4c833752 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Wed, 22 Feb 2012 22:15:59 +0000 Subject: sstatesig.py: Add handling for machine specific module dependencies Adding dependencies on machine specific recipes from generic packages causes a rebuild of the generic package per machine if using signatures for the stamp files which is unacceptable. We need to declare that RRECOMMENDS on kernel-module-* are safe and that we shouldn't care about these machine specific dependencies from a stamp perspective. This change adds code which does this. It depends on a change in bitbake to expose the dataCache object which can be used to make the calculations we need to allow this to work correctly.
