Look in tests/qtest/meson.build for lines like:

  config_all_devices.has_key('CONFIG_TPM_TIS_ISA') ? ['tpm-tis-test'] : [])

It seems we have a bunch of logic for qtests_i386 and qtests_aarch64
which isn't applied to the qtests list. Commenting those out I still get
the full list:

 meson test --list | grep tpm
 qemu:qtest+qtest-aarch64 / qtest-aarch64/tpm-tis-device-test
 qemu:qtest+qtest-aarch64 / qtest-aarch64/tpm-tis-device-swtpm-test
 qemu:qtest+qtest-aarch64 / qtest-aarch64/tpm-tis-i2c-test
 qemu:qtest+qtest-arm / qtest-arm/tpm-tis-i2c-test
 qemu:qtest+qtest-i386 / qtest-i386/tpm-crb-test
 qemu:qtest+qtest-i386 / qtest-i386/tpm-crb-swtpm-test
 qemu:qtest+qtest-i386 / qtest-i386/tpm-tis-test
 qemu:qtest+qtest-i386 / qtest-i386/tpm-tis-swtpm-test
 qemu:qtest+qtest-x86_64 / qtest-x86_64/tpm-crb-test
 qemu:qtest+qtest-x86_64 / qtest-x86_64/tpm-crb-swtpm-test
 qemu:qtest+qtest-x86_64 / qtest-x86_64/tpm-tis-test
 qemu:qtest+qtest-x86_64 / qtest-x86_64/tpm-tis-swtpm-test

But I guess there are there to ensure the dependencies are correct so
I'm sure that's not the right fix.

Paolo,

Where is that meant to be done?
