[PATCH v4 4/5] ACPI 2.0 / AML: Enable correct ACPI subsystem initialization order for new table loading mode

Show all headers | View raw

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.
