/*
* How to add or update the tests or commit changes that affect ACPI tables:
* Contributor:
* 1. add empty files for new tables, if any, under tests/data/acpi
* 2. list any changed files in tests/qtest/bios-tables-test-allowed-diff.h
* 3. commit the above *before* making changes that affect the tables
*
* Contributor or ACPI Maintainer (steps 4-7 need to be redone to resolve conflicts
* in binary commit created in step 6):
*
* After 1-3 above tests will pass but ignore differences with the expected files.
* You will also notice that tests/qtest/bios-tables-test-allowed-diff.h lists
* a bunch of files. This is your hint that you need to do the below:
* 4. Run
* make check V=1
* this will produce a bunch of warnings about differences
* beween actual and expected ACPI tables. If you have IASL installed,
* they will also be disassembled so you can look at the disassembled
* output. If not - disassemble them yourself in any way you like.
* Look at the differences - make sure they make sense and match what the
* changes you are merging are supposed to do.
* Save the changes, preferably in form of ASL diff for the commit log in
* step 6.
*
* 5. From build directory, run:
* $(SRC_PATH)/tests/data/acpi/rebuild-expected-aml.sh
* 6. Now commit any changes to the expected binary, include diff from step 4
* in commit log.
* Expected binary updates needs to be a separate patch from the code that
* introduces changes to ACPI tables. It lets the maintainer drop
* and regenerate binary updates in case of merge conflicts. Further, a code
* change is easily reviewable but a binary blob is not (without doing a
* disassembly).
* 7. Before sending patches to the list (Contributor)
* or before doing a pull request (Maintainer), make sure
* tests/qtest/bios-tables-test-allowed-diff.h is empty - this will ensure
* following changes to ACPI tables will be noticed.
*
* The resulting patchset/pull request then looks like this:
* - patch 1: list changed files in tests/qtest/bios-tables-test-allowed-diff.h.
* - patches 2 - n: real changes, may contain multiple patches.
* - patch n + 1: update golden master binaries and empty
* tests/qtest/bios-tables-test-allowed-diff.h
