current maintainer trees (testing/semihosting/plugins) Hi All, I've wrapped up all my maintainer trees into a single branch to minimise the disruption of multiple pull requests. Most stuff has already been reviewed but in short we have: - some cleanups and tweaks for gitlab - a new playbook to install gitlab runners - a proposed re-org of the front about section - a few semihosting fixes (with docs ;-) - a bunch of tsan fixes touching tcg and plugins - fixing some plugin races - expunging the last vestiges of perl from the build system The following patches need review: tests/tcg: add memory-sve test for aarch64 semihosting: add semihosting section to the docs docs: add a proper feature overview in "About QEMU" tests/unit: drop hacky race avoidance in test-io-channel-command gitlab: just use plain --cc=clang for custom runner build gitlab: add FF_SCRIPT_SECTIONS for timings scripts/ci: update gitlab-runner playbook to use latest runner
