Subject: [PATCH v4 4/5] ACPI 2.0 / AML: Enable correct ACPI subsystem initialization order for new table loading mode
Date: Tue, 21 Jun 2016 12:34:45 +0800	[thread overview]
Message-ID: <7f8480f1767105a02d28de24a7a3aea265bbdc14.1466479787.git.lv.zheng@intel.com> (raw)
In-Reply-To: <cover.1466479787.git.lv.zheng@intel.com>

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.
