linux: drop the option to use the same version as that of the headers

2016-02-06T09:58:24+00:00

It is no longer meaningful, now that we have the option to use the kernel version for the linux headers, as it is more logical and more versatile. Add it to legacy. Signed-off-by: "Yann E. MORIN" Cc: Thomas Petazzoni Cc: Peter Korsgaard Cc: Arnout Vandecappelle Signed-off-by: Thomas Petazzoni

package/linux-headers: add option to use same sources as the kernel

2016-02-02T08:55:58+00:00

Some heavily (and most often improperly) modified Linux kernels may export new APIs to userland, so as to speak to custom hardware or custom kernel facilities. However, we currently have no easy way to use such kernels as a source for the linux-headers package, which precludes having those userland headers intalled for userland applications to use them. We do have a way for the kernel to use the same version as for the headers, but that is definitely not enough, as the linux-headers package has a version choice that is far less versatile and capable than that of the linux package. Add a new option for the linux-headers package, for the user to specify that the version (really, the sources) of the kernel be used to install the headers from. We do that by making linux-headers patch-depend on the linux package. We can't have linux-header simply depend on linux, because the simple dependency means the the dependee will be configured, built and installed before the dependent is configured. And since linux is a target package, it depends on the toolchain, which internally dependes on linux-headers, which would depend on linux, and we'd get a circular dependency. Using patch-depend will ensure that linux is extracted and patched before linux-headers is extracted, which is really all we need. Then, we install the headers from the linux source tree, rather than from linux-headers' source tree (as there's nothing in there!). Since we need to install a private set for uClibc (see cde947f, uclibc: prevent rebuilding after installation to staging), we explicitly set INSTALL_HDR_PATH when calling the kernel' install-headers rule in LINUX_HEADERS_CONFIGURE_CMDS, so that the headers are installed in linux-headers' $(@D) instead of linux' $(@D). Finally, as there is no way to know the kernel version in this case, we must still prompt the user for the kernel series the headers are from (like we do for a custom version) and check for consistency at build time. Note however that this still leaves users that want to built their such-kernel outside of Buildroot out in the cold. [Peter: drop comment as suggested by Thomas] Signed-off-by: "Yann E.

linux: add blind kconfig option to require kernel modules

2015-12-29T22:50:11+00:00

Currently, packages that need the kernel to have support for laodable modules have two ways to require it: - either the use the kernel-module infra, which does it automatically, - or they do not use it, and they need to require it manually by setting the corresponding Makefile variable; however, they must only set it when they are actually enabled, which makes for a slightly cumbersome and ugly code, like: ifeq ($(BR2_PACKAGE_FOO),y) LINUX_NEEDS_MODULES = y endif Introduce a new blind Kconfig option that packages can select to signify they need kernel modules. That Kconfig option is then used to set the Makefile variable. It makes it cleaner: - code is simpler (one Kconfig line instead of a Makefile if-block, - this is handled at the Kconfig level, which is where we usually handle such dependencies. Packages will be updated in follow-up commits. Reported-by: Thomas Petazzoni Signed-off-by: "Yann E. MORIN" Cc: Thomas Petazzoni Signed-off-by: Peter Korsgaard
