I think in 11fb99e6f48..e542b71805d we missed an extra patch
for qtests. Probably (untested):
Shouldn't we have seen test compilation errors already?

I didn't go down this route for the build system (as you show below)
because in this series we are testing ACPI tables and I introduce the
reference to enum TPMVersion here, which wasn't needed before. The
alternative may be to go into 8/9 and eliminate all TPM code if
CONFIG_TPM is not set. The introduction of the enum now passes the tests
with --enable-tpm and --disable-tpm.

Otherwise the BIOS test are skipped due to this here:


static void test_acpi_tcg_tpm(const char *machine, const char *tpm_if,
                               uint64_t base, enum TPMVersion tpm_version)
{
#ifdef CONFIG_TPM
[...]

#else
     g_test_skip("TPM disabled");
#endif
}

So I didn't want to clutter this code with more #ifdef CONFIG_TPM but
maybe that would be the right solution.
IMO the "right" solution is to check via QMP if TMP is supported
or not. This is now doable since commit caff255a546 ("tpm: Return
QMP error when TPM is disabled in build").

That above g_test_skip() could be moved to the top of the function and be preceded by a QMP check for whether TPM is supported.
