6668 2014-08-29 08:41:39 +0000 Kernel recipes imeta-intel override contents of KERNEL_MODULE_AUTOLAD 2014-09-29 15:03:40 +0000 1 1 7 Build System, Metadata & Runtime BSPs bsps-meta-intel unspecified x86 Multiple VERIFIED FIXED Medium+ normal 1.7 M4 1 josep.puigdemont nitin.a.kamble alexandru.c.georgescu tom.zanussi andrax.g.necula --- --- No (bug/feature does not impact docs) oldest_to_newest 45327 0 josep.puigdemont 2014-08-29 08:41:39 +0000 The current kernel recipes in the meta-intel layer use the following convention for kernel modules that need to be autoloaded: KERNEL_MODULE_AUTOLOAD_core2-32-intel-common += "uio" When using the override with the += operator we're only appending to the override variable (KERNEL_MODULE_AUTOLOAD_core2-32-intel-common). Bitbake will thus eventually substitue KERNEL_MODULE_AUTOLOAD by whatever KERNEL_MODULE_AUTOLOAD_core2-32-intel-common contains, if core2-32-intel-common is found in the OVERRIDES variable, effectively overriding all previous content of the variable KERNEL_MODULE_AUTOLOAD that other layers may have modified. Unless this is intended, the preferred way to add a kernel module to the autoload list would probably be the following: KERNEL_MODULE_AUTOLOAD_append_core2-32-intel-common = " uio" This will append to the KERNEL_MODULE_AUTOLOAD variable in case core2-32-intel-common is found in the OVERRIDES variable (i.e. it will not override the variable as it happened in the previous case). Steps to reproduce the issue: clone poky, meta-intel and meta-virtualization from git.yoctoproject.org clone meta-openembedded from git.openembedded.org Make sure the following layers are added in conf/bblayers.conf: meta-intel meta-openembedded/meta-networking meta-virtualization In conf/local.conf make sure MACHINE is set properly, and add some kernel modules to the image: MACHINE = "intel-corei7-64" IMAGE_INSTALL_append = " kernel-module-kvm kernel-module-kvm-intel kernel-module-uio" Now build core-image-minimal: bitbake core-image-minimal In the final image, check the contents of /etc/modules-load.d/. Although meta-virtualization adds kvm and kvm-intel to KERNEL_MODULE_AUTOLOAD, the directory only contains the "uio" module. This is because all other modules have been overriden by the kernel recipes in meta-intel. 45328 1 2099 josep.puigdemont 2014-08-29 08:44:04 +0000 Created attachment 2099 Patch to fix this issue After applying this patch, and with the same setup provided in the description, build again core-image-minimal. Check once more the contents of the /etc/modules-load.d/ directory. This time you should be able to see all modules: kvm.conf kvm-intel.conf uio.conf 45392 2 tom.zanussi 2014-09-04 14:39:48 +0000 http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel/commit/?id=b89a7c533df4fa17d8c239e674b0af83253a65b6 45945 3 andrax.g.necula 2014-09-29 14:52:20 +0000 I followed the steps for reproducing the issue, but I get this error ERROR:No recipes available for: /home/andra/WEEKLY/pokynou/poky/meta-virtualization/recipes-kernel/linux/linux-yocto_3.4.bbappend host Ubuntu 14.04 poky:8ac8eca2e3bd8c78e2b31ea974930ed0243258a3 I thinking that the virtualization layer is not updated for the linux-yocto 3.4 kernel.

You're right, the .bbappend for the 3.4 linux version should be removed in the meta-virtualization layer, and a new one for 3.17 be added to line up with the current available kernel versions in the upstream yocto project. For the moment you can build with BB_DANGLINGAPPENDS_WARNONLY="1" in your local.conf, so you will only get a warning instead of an error. > Thank in advance 2099 2014-08-29 08:44:04 +0000 2014-08-29
