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 51 */ 52 53 #include "qemu/osdep.h" 54 #include <glib/gstdio.h> 55 #include "qemu-common.h" 56 #include "hw/firmware/smbios.h" 57 #include "qemu/bitmap.h" 58 #include "acpi-utils.h" 59 #include "boot-sector.h" 60 #include "tpm-emu.h" 61 #include "hw/acpi/tpm.h" 62 63 64 #define MACHINE_PC "pc" 65 #define MACHINE_Q35 "q35" 66 67 #define ACPI_REBUILD_EXPECTED_AML "TEST_ACPI_REBUILD_AML" 68 69 typedef struct { 70 bool tcg_only;
