The Vulkan intel driver depends on the i965 dri driver: https://cgit.freedesktop.org/mesa/mesa/tree/configure.ac?h=12.0#n1653 and a sha1 implementation: https://cgit.freedesktop.org/mesa/mesa/tree/configure.ac?h=12.0#n1656 The Vulkan driver needs linux/memfd.h https://cgit.freedesktop.org/mesa/mesa/tree/src/intel/vulkan/anv_allocator.c?h=12.0#n30 which is not available in kernel headers older than 3.18: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/log/include/uapi/linux/memfd.h?id=refs/tags/v3.18.36 The Vulkan driver makes use of ifunc https://cgit.freedesktop.org/mesa/mesa/tree/src/intel/vulkan/anv_entrypoints_gen.py?h=12.0#n287 which is not available on uClibc: https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config.gcc;h=82cc9a9959b5ab57c0b8779e054b80cdb95f169b;hb=gcc-6-branch#l1485 https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=e6cdd6b1755033e8f416efaa4334d1294c0a43c6 The Vulkan driver makes use of static_assert https://cgit.freedesktop.org/mesa/mesa/tree/src/intel/vulkan/anv_private.h?h=12.0#n153 Compiling the Vulkan driver with uClibc and musl fails, therefore this driver is glibc-only. Although the configure script does not check for dri3 support if the Intel Vulkan driver is enabled it needs it nonetheless: https://cgit.freedesktop.org/mesa/mesa/tree/src/intel/vulkan/anv_wsi_x11.c?h=12.0#n682 Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> |

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 Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
