4 Subject: [PATCH] wireguard: selftests: import harness makefile for test suite
5
6 commit 65d88d04114bca7d85faebd5fed61069cb2b632c upstream.
7
8 WireGuard has been using this on build.wireguard.com for the last
9 several years with considerable success. It allows for very quick and
10 iterative development cycles, and supports several platforms.
11
12 To run the test suite on your current platform in QEMU:
13
14 $ make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
15
16 To run it with KASAN and such turned on:
17
18 $ DEBUG_KERNEL=yes make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
19
20 To run it emulated for another platform in QEMU:
21
22 $ ARCH=arm make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
23
24 At the moment, we support aarch64_be, aarch64, arm, armeb, i686, m68k,
25 mips64, mips64el, mips, mipsel, powerpc64le, powerpc, and x86_64.
26
27 The system supports incremental rebuilding, so it should be very fast to
28 change a single file and then test it out and have immediate feedback.
29
30 This requires for the right toolchain and qemu to be installed prior.
31 I've had success with those from musl.cc.
32
33 This is tailored for WireGuard at the moment, though later projects
34 might generalize it for other network testing.
