@fionescu You can see the hardware that gets subject to regular test suite runs here: https://releng.netbsd.org/test-results.html

In summary, GuruPlug (ARMv5), CUBIETRUCK (ARMv7 big endian), HummingBoard Pulse (AArch64), LANDISK USL-5P (SuperH), Macintosh G4 Quicksilver (PowerPC), Sun v210 (SPARC64).

Of course, the test suite can take a very long time to run on slower hardware.
