Ani, what previously worked is the is there weren't _any_ expected blobs (exact match/fallback) found a new table would be dumped. So then later 'git status' would show a list of new files. With this commit it's however not dumping new files files, and explodes at #5 0x000055555556808e in load_expected_aml (data=0x7fffffffd7b0) at tests/qtest/bios-tables-test.c:414 #6 0x00005555555676b0 in dump_aml_files (data=0x7fffffffd7b0, rebuild=true) at tests/qtest/bios-tables-test.c:256 sure it can be worked around by manually creating empty files for expected files but if it's a new machine type, one has to create a bunch of them basically running multiple iterations of rebuild in V=2 mode to see what's missing. (IMHO cure turned out to be worse than illness) for reproducing create a test for other than default machine type, ex: test_data data = { .machine = "pc-i440fx-2.0", .variant = ".pc_legacy", }; is it possible to fix it so that one doesn't have to create empty files manually? > > This would make analyzing changes to tables less confusing and there would > be no need to clean useless untracked files when there are no table changes. > > CC: peter.maydell@linaro.org > Signed-off-by: Ani Sinha <anisinha@redhat.com> > Message-Id: <20231107044952.5461-1-anisinha@redhat.com> > Reviewed-by: Michael S.

Yes this was the original complaint from Peter.
