search for: srctree

Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I w...

The following patchset implements 3 seperate series of changes. External Building ================= Patches 1 through 8 enable to use of klibc's build system while leaving the src tree pristine (and potentially read only). Specifically: - srctree=<Sources for klibc> - objtree=<Ouput directory for klibc> - KLIBCKERNELSRC=<Kernel sources> - KLIBCKERNELOBJ=<Kernel output directory> As an example, with these patches, one can call 'make' as follows (assuming /usr/local/src/linux-2.6 are kernel sources and o...

Hi Peter & others. Here are three patches that does the following: #1 - Update kbuild part of klibc so make clean works Adds gzip including a sample kbuild file #2 - Factor out definition of usr/ to two variables #3 - Move kbuild files to reflect location in the kernel As requested in earlier mail I need a bit of guidiance of what you expect from the kernel integrated parts of klibc.

This patchset applies to klibc mainline. This patchset introduces the ability to kinit to execute scripts or executable files present in in the initramfs before switching over to the root filesystem. This functionality is implemented in a newly introduced run_parts() call, which calls scandir() to iterate through files which in then executes in sequence. run_parts() is also available as a

Hi Peter, I'm looking at using klibc for a small initramfs for our production servers as a way for us to change a bunch of sysctls at boot as well as handle root= logic. To make my life easier in our build environment, I'd like to build klibc outside of the linux tree and in an always clean source tree (potentially a read-only nfs share), so I'd like to extend the build to support
