/*
 * 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=2
 * 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
