This is your hint that you need to do the below: 23 * 4. Run 24 * make check V=1 25 * this will produce a bunch of warnings about differences 26 * beween actual and expected ACPI tables. If you have IASL installed, 27 * they will also be disassembled so you can look at the disassembled 28 * output. If not - disassemble them yourself in any way you like. 29 * Look at the differences - make sure they make sense and match what the 30 * changes you are merging are supposed to do. 31 * 32 * 5. From build directory, run: 33 * $(SRC_PATH)/tests/data/acpi/rebuild-expected-aml.sh 34 * 6. Now commit any changes. 35 * 7. Before doing a pull request, make sure tests/bios-tables-test-allowed-diff.h 36 * is empty - this will ensure following changes to ACPI tables will 37 * be noticed. 38 */ 39 40 #include "qemu/osdep.h" 41 #include <glib/gstdio.h> 42 #include "qemu-common.h" 43 #include "hw/firmware/smbios.h" 44 #include "qemu/bitmap.h" 45 #include "acpi-utils.h" 46 #include "boot-sector.h" 47 48 #define MACHINE_PC "pc" 49 #define MACHINE_Q35 "q35" 50 51 #define ACPI_REBUILD_EXPECTED_AML "TEST_ACPI_REBUILD_AML" 52 53 typedef struct { 54 bool tcg_only;
