classes/kernel: move module postinst commands to kernel-base

2014-03-22T12:12:20+00:00

Since kernel-base is the package that contains the files that depmod needs to run, we should be running depmod from the kernel-base postinstall rather than kernel-image. Fixes [YOCTO #5392].

kernel.bbclass, base.bbclass: Fix support for old kernel configuration

2014-02-13T11:41:22+00:00

This solves a regression introduced by OE-Core:9b75f6a (kernel: use oldnoconfig before yes '' | make oldconfig). The original oe_runmake explicitly calls 'die' command in case of failure so the fallback code never runs. The fallback code needs to handle the oe_runmake return code to call the backward compatible callback so we introduced a new command called oe_runmake_call which is used by oe_runmake. This does not change the functional behaviour of oe_runmake so it avoids any change except for the code which does need to handle the oe_runmake exit code.

kernel: use oldnoconfig before yes '' | make oldconfig

2014-02-11T11:56:56+00:00

When using a defconfig, using yes '' | make oldconfig may not result in the correct configuration being set. For example: $ ARCH=mips make qi_lb60_defconfig # # configuration written to .config # $ grep USB_ETH .config CONFIG_USB_ETH=y # CONFIG_USB_ETH_RNDIS is not set # CONFIG_USB_ETH_EEM is not set $ cp arch/mips/configs/qi_lb60_defconfig .config $ yes '' | make ARCH=mips oldconfig [...] $ grep USB_ETH .config CONFIG_USB_ETH=m # CONFIG_USB_ETH_RNDIS is not set # CONFIG_USB_ETH_EEM is not set Using make olddefconfig solves that but we'll use the oldnoconfig alias for backward compatibility with older kernels. $ cp arch/mips/configs/qi_lb60_defconfig .config $ make ARCH=mips oldnoconfig scripts/kconfig/conf --olddefconfig Kconfig # # configuration written to .config # $ grep USB_ETH .config CONFIG_USB_ETH=y # CONFIG_USB_ETH_RNDIS is not set # CONFIG_USB_ETH_EEM is not set (From OE-Core rev: 9b75f6a5786ff7b2e6219d78b38f0032f100c660) Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

kernel: stop using -exec rm for deleting files

2014-02-11T11:56:56+00:00

Removing files from the source tree via find, exec and rm is not the most efficient operation, due to (among other things) the many forked processes. If we use -delete, it saves a significant amount of time. But -delete does not work with -prune (since it forces -depth). To maintain the lib, tools and scripts source files, we can hide them temporarily, skip their hidden directories and then finally restore them. Time for install before this change: real 2m48.563s user 0m35.220s sys 0m33.036s Time for install after this change: real 1m21.301s user 0m33.160s sys 0m28.388s We could further speed this up by using inline perl to delete the files, but that complexity is avoided for now.

kernel.bbclass: Fix empty modules directory QA issue

2014-02-02T11:22:08+00:00

If a kernel is built without any external modules (aka no CONFIG_*=m), then during a modules_install of the kernel an empty directory is created at /lib/modules/${KERNEL_VERIONS}/kernel. This is behaviour of the kernel infrastructure, the directory would normally be populated with the modules that were built. However because of the expectations of kernel-modules-split, no packages are created when there are no modules and an empty directory lingers. This raises QA issues as warning or errors (depending on the distro). The following patch changes the kernel_do_install task to check if the directory is empty and if so removes it.

classes/module_strip: remove

2013-12-12T23:09:15+00:00

This class has been empty since 2010, so we shouldn't need it anymore. A check of common layers suggests there shouldn't be any references to it outside of OE-Core. (From OE-Core rev: 3c4557df95e3c60ef938c53f00bb1d7f765fe0ef) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

Revert "kernel: restore scripts in the sysroot"

2013-11-29T09:52:58+00:00

This reverts commit 6a6735cb98d529c8c5376aedb5c951339f54fe96. The module class already ensures the scripts are rebuilt correctly. Running this at sstate installation time is problematic since it can require the cross compiler. Adding such a dependency would cause issues of its own.

kernel.bbclass: Stop bundle_initramfs thwarting sstate cache and fix race

2013-11-24T12:25:35+00:00

The new do_bundle_initramfs task introduced in 609d5a9ab9e58bb1c2bcc2145399fbc8b701b85a defeats using the sstate cache. The kernel is resurrected from the sstate cache but ends up being built again since do_bundle_initramfs depends on do_compile. The task is no longer nostamp to avoid causing unnecessary rebuilds. The sstate checksum stamps should know when to rebuild. The task now runs before do_deploy and part of the work has been moved to do_deploy where it now writes to ${DEPLOYDIR} rather than ${DEPLOY_DIR_IMAGE} so that the files end up in sstate. The task can also race against do_install since both call into the kernel build system. This is fixed by making do_bundle_initramfs run after do_install (which therefore also fixes the problem that 3baa63b4d588c3262254528b406ede265dd117bf was addressing.)
