In which case the > ctx.machine_name will be NULL? Here I thought about the PPC64 tests inheriting the PPC32 ones, and maybe someone update the tests/Makefile.include and this test will run on unexpected architectures. So if the machine is NULL (another arch) we don't crash and return successfully, so the testsuite continue. I might add a comment such: if (ctx.machine_name) { /* Only run whitelisted architecture. */ ret = g_test_run(); } But maybe it is simpler to do at the beginning of main(): if (g_str_equal(arch, "i386") || g_str_equal(arch, "x86_64")) { ... ctx.fw_cfg = mm_fw_cfg_init(0xf0000510); } else { return 0; } What do you think?

In that case, the original initializer will remain in effect, from: QTestCtx ctx = {}; (Admittedly, this is an ugly GNU-ism; for standard C, it should be QTestCtx ctx = { 0 }; but the GNU-ism is used quite frequently in QEMU elsewhere, so meh :) ) Thanks Laszlo

(Cf commit message for commit 039d4e3df0049bdd.) thanks -- PMM

Then in this case, I prefer 'just return'. There is no need do other things for non-support arch. This is just like some other case, such as usb-hcd-ehci-test.c and ahci-test.c. Also, I don't find any conditional 'g_test_run' calling.

We have been restricting our fw_cfg tests to the PC machine, which is a little-endian architecture. The fw_cfg device is also used on the SPARC and PowerPC architectures, which can run in big-endian configuration. Since we want to be sure our device does not regress regardless the endianess used, enable this test one these targets. The NUMA selector is X86 specific, restrict it to this arch.
