14  * How to add or update the tests:
15  * Contributor:
16  * 1. add empty files for new tables, if any, under tests/data/acpi
17  * 2. list any changed files in tests/qtest/bios-tables-test-allowed-diff.h
18  * 3. commit the above *before* making changes that affect the tables
19  *
20  * Contributor or ACPI Maintainer (steps 4-7 need to be redone to resolve conflicts
21  * in binary commit created in step 6):
22  *
23  * After 1-3 above tests will pass but ignore differences with the expected files.
24  * You will also notice that tests/qtest/bios-tables-test-allowed-diff.h lists
25  * a bunch of files. This is your hint that you need to do the below:
26  * 4. Run
27  *      make check V=1
28  * this will produce a bunch of warnings about differences
29  * beween actual and expected ACPI tables. If you have IASL installed,
30  * they will also be disassembled so you can look at the disassembled
31  * output. If not - disassemble them yourself in any way you like.
32  * Look at the differences - make sure they make sense and match what the
33  * changes you are merging are supposed to do.
34  * Save the changes, preferably in form of ASL diff for the commit log in
35  * step 6.
36  *
37  * 5. From build directory, run:
38  *      $(SRC_PATH)/tests/data/acpi/rebuild-expected-aml.sh
39  * 6. Now commit any changes to the expected binary, include diff from step 4
40  *    in commit log.
41  * 7. Before sending patches to the list (Contributor)
42  *    or before doing a pull request (Maintainer), make sure
43  *    tests/qtest/bios-tables-test-allowed-diff.h is empty - this will ensure
44  *    following changes to ACPI tables will be noticed.
45  *
46  * The resulting patchset/pull request then looks like this:
47  * - patch 1: list changed files in tests/qtest/bios-tables-test-allowed-diff.h.
48  * - patches 2 - n: real changes, may contain multiple patches.
49  * - patch n + 1: update golden master binaries and empty
50  *   tests/qtest/bios-tables-test-allowed-diff.h
