-Subject: [PATCH] wireguard: selftests: import harness makefile for test suite
-
-commit 65d88d04114bca7d85faebd5fed61069cb2b632c upstream.
-
-WireGuard has been using this on build.wireguard.com for the last
-several years with considerable success. It allows for very quick and
-iterative development cycles, and supports several platforms.
-
-To run the test suite on your current platform in QEMU:
-
- $ make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
-
-To run it with KASAN and such turned on:
-
- $ DEBUG_KERNEL=yes make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
-
-To run it emulated for another platform in QEMU:
-
- $ ARCH=arm make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
-
-At the moment, we support aarch64_be, aarch64, arm, armeb, i686, m68k,
-mips64, mips64el, mips, mipsel, powerpc64le, powerpc, and x86_64.
-
-The system supports incremental rebuilding, so it should be very fast to
-change a single file and then test it out and have immediate feedback.
-
-This requires for the right toolchain and qemu to be installed prior.
-I've had success with those from musl.cc.
-
-This is tailored for WireGuard at the moment, though later projects
-might generalize it for other network testing.
