kernel: fix race condition between compile_kernelmodules and shared_workdir

2015-11-24T15:50:27+00:00

Fixes https://bugzilla.yoctoproject.org/show_bug.cgi?id=8127 which causes [ 1225.089323] 8189es: Unknown symbol cfg80211_scan_done (err -22) [ 1225.095916] 8189es: no symbol version for cfg80211_remain_on_channel_expired when loading external compiled 8189es module.

kernel.bbclass: fix the bug of checking the existing sections in do_strip()

2015-10-01T06:43:37+00:00

Ross reported the following waring when building edgerouter BSP: WARNING: Section not found: .comment The reason is that the testing of the existing sections in do_strip() returned the wrong value. Please see the following code in do_strip(): for str in ${KERNEL_IMAGE_STRIP_EXTRA_SECTIONS}; do { if [ "$headers" != *"$str"* ]; then bbwarn "Section not found: $str"; fi "$CROSS_COMPILE"strip -s -R $str ${KERNEL_OUTPUT} }; done The "*" doesn't have special meaning in the if string test, so it will return true even the $str is a substring of $headers. Fix this issue by replacing it with "! (echo "$headers" | grep -q "^$str$")".

kernel.bbclass: do not mv/link sources when externalsrc enabled

2015-09-09T13:27:49+00:00

If externalsrc is enabled the 'do_unpack' task is run if the recipe has some local source files. In the case of kernel recipe this caused the (externalsrc) source tree to be moved/symlinked. This patch prevents the behaviour, making sure the source tree is not moved around when externalsrc is enabled. Instead of moving the source tree, STAGING_KERNEL_DIR will be a symlink to it.

kernel.bbclass: add the runtime dependency on kernel-vmlinux for kernel-image

2015-09-03T11:43:23+00:00

When a BSP uses vmlinux for boot, the kernel-image package is just empty. But by default the kernel-vmlinux is not installed. Then the pkg_postinst_kernel-image() would create a symlink to a non-existent file. Fix this by adding the runtime dependency on kernel-vmlinux for kernel-image if the KERNEL_IMAGETYPE is "vmlinux".

kernel.bbclass: dont assume ${B}/include/generated exists

2015-08-11T16:28:50+00:00

Older kernels (e.g. 2.6.32) don't create an include/generated directory, so check that the directory exists before trying to copy files from it in do_shared_workdir().

kernel: fix path assumptions in tasks

2015-07-16T14:09:21+00:00

Several of the kernel class tasks were making assumptions about what directory they were executed in. Clarify the code by making paths absolute or passing -C to oe_runmake. (From OE-Core rev: d596286bc4cf19774447b136a27acf3c61aad2ff) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

kernel: Pull uImage generation into separate class

2015-05-26T09:57:51+00:00

Pull the uImage image format generation from kernel.bbclass into a separate kernel-uimage.bbclass. Introduce new KERNEL_CLASSES variable, which allows registration of additional classes which implement new kernel image types. The default value of is to register kernel-uimage to preserve the original behavior.

kernel: Pull out the linux.bin generation

2015-05-26T09:57:51+00:00

Pull the generation of linux.bin image, which is then packed into uImage, into a separate function. No functional change.

kernel: Rework do_uboot_mkimage

2015-05-26T09:57:51+00:00

Rework the function so part it's internals can be re-used by fitImage image type. The name of the temporary file , linux.bin , is recycled a little more as it's now used for both the case where it is gzip compressed and where it is not. This should be fine, since the file is temporary and removed after the uImage was created anyway. There is no functional change here.

kernel: Clean up KERNEL_IMAGETYPE_FOR_MAKE

2015-05-26T09:57:51+00:00

Remove the lambda function setting KERNEL_IMAGETYPE_FOR_MAKE and instead set it in the anonymous python function. This also allows us to handle image types which are not supported directly by kernel, but require some other kernel target to be built. This is the case for example with the fitImage, which is the uImage successor. There is no functional change.
