| Subject | [PATCH v2 3/4] ACPI 2.0 / AML: Enable correct ACPI subsystem initialization order for new table loading mode |
| Date | 2016-05-13 07:40 +0200 |

This patch enables the following initialization order for the new table
loading mode (which is enabled by setting
acpi_gbl_parse_table_as_term_list to TRUE):
1. Install default region handlers (SystemMemory, SystemIo, PciConfig,
EmbeddedControl via ECDT) without evaluating _REG;
2. Load the table and execute the module level AML opcodes instantly.
