[Test Case] Tested with ACPI tables from Dell's Precision 3530. The outputs are almost the same as ones from "acpidump". The difference is the order of ACPI tables in the output but the order is not important. 1. run dump_acpi_tables.py 2. run acpidump 3. compare the outputs Note: acpidump is from acpica-tools [Regression Potential] Formats were changed to be the same as outputs from "acpidump", but known tools, such as acpiexec and fwts, by default reads outputs from acpidump and they do not reply on spaces and upper/lower cases. [Other Info] See original bug reports as below: dump_acpi_tables.py generates log files that is similar as the output from "acpidump" in acpica-tools. The output can be passed to other utilities in acpica-tools and fwts. It, however, has some subtle differences and some errors. Summary: 1. ACPI tables have 4-char signatures - meaning SSDT's are SSDT, not SSDT1, SSDT2 and so on. Each table is unique by its table ID. Original: SSDT1, SSDT2, SSDT3 ... Changed: SSDT, SSDT, SSDT ... 2. (Minor) acpidump outputs are all in upper cases 3. (Minor) acpidump offset are aligned by data, not address Original: FFF0: 53 41 56 43 52 44 43 41 4E 43 52 4E 72 4E 50 4D SAVCRDCANCRNrNPM 10000: 56 0A 04 00 0C FC FF FF FF 0A 03 0A 03 52 44 43 V............RDC Changed: FFF0: 53 41 56 43 52 44 43 41 4E 43 52 4E 72 4E 50 4D SAVCRDCANCRNrNPM 10000: 56 0A 04 00 0C FC FF FF FF 0A 03 0A 03 52 44 43 V............RDC 4.
