That's great, good to know that you're still interested in TCI! ... but
I think one of the main problems is still that we completely lack test
coverage for TCI - the code always is in danger to bit-rot if it is not
tested by default.

I could maybe have a try to add some test to our .gitlab-ci.yml file ...
if you or somebody else could add one to .travis.yml, that would be
great. Something like:

 - ./configure --enable-tcg-interpreter 
--target-list=alpha-softmmu,ppc64-softmmu,i386-softmmu,sparc-softmmu,microblaze-softmmu,moxie-softmmu,arm-softmmu,hppa-softmmu
 - make
 - make tests/boot-serial-test
 - QTEST_QEMU_BINARY="alpha-softmmu/qemu-system-alpha"  ./tests/boot-serial-test
 - QTEST_QEMU_BINARY="ppc64-softmmu/qemu-system-ppc64"  ./tests/boot-serial-test
 - ...
