Bump Xen from 4.19.5 to 4.21.1. Resolved in version bump: - 0002-Arm-platforms-fix-build-with-gcc15.patch Upstream: https://xenbits.xen.org/gitweb/?p=xen.git;a=commitdiff;h=39f95089e2ba15c5438ce904c0cbbd8d79d3e6e7 The git-checkout.sh fix for non-master branch checkout is now included: https://xenbits.xenproject.org/gitweb/?p=xen.git;a=commitdiff;h=01fb23dd71006d87e874f310e9c50f31582f274e Remaining patches refreshed for updated context: - 0001-No-trace-backend.patch (Buildroot specific, cross-compile workaround) - 0002-Update-linker-flags.patch (Buildroot specific, cross-compile workaround) Starting with Xen 4.20, qemu-xen is no longer bundled in the release tarball. Add a new qemu-xen package that provides the qemu-xen source tree with required meson subprojects pre-populated. This avoids any network access during the build. New dependencies: - qemu-xen (provides qemu-xen source for tools build) - host-python-distlib (needed by QEMU's mkvenv) The qemu-xen package: - Fetches qemu-xen via git (without recursive submodules to avoid massive ROM downloads) - Pre-populates required meson subprojects (keycodemapdb, berkeley-softfloat-3, berkeley-testfloat-3) from gitlab archives - Applies packagefiles overlays (meson.build) for subprojects that need them - Removes .wrap files for unused subprojects to prevent any network access attempts during the build - Patches xen_native.h #error to #warning for cross-compile Tested with: support/testing/run-tests \ -d dl -o output_folder \ tests.package.test_xen.TestXenAarch64 support/testing/run-tests \ -d dl -o output_folder \ tests.package.test_xen.TestXenArmv7 Both aarch64 and arm32 runtime tests pass.

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 https://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.
