linux-tools opportunistically set linux as only a patch dependency. This unfortunately introduces a race condition in the shared linux scripts when using PER_PACKAGE_DIRECTORIES and using top level parallelism. The race manifests as the error "/bin/sh: 1: scripts/basic/fixdep: Permission denied". This happens when the linux package and the linux-tools package are being compiled in parallel. The linux-tools currently using fixdep are perf and rtla. When the timing is correct, perf, rtla, or the kernel Makefile will try to use fixdep while one of the others is compiling fixed, resulting in fixdep being briefly not available. To fix this, set linux as a build dependency instead of a patch dependency. Signed-off-by: Charlie Jenkins <charlie@rivosinc.com> Reviewed-by: Yann E.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
