Forward-port the following commit from seabios: commit 995bbeef78b338370f426bf8d0399038c3fa259c Author: Paul Menzel <paulepanter@users.sourceforge.net> Date: Thu Oct 3 11:30:52 2013 +0200 The ASL Optimizing Compiler version 20130823-32 [Sep 11 2013] issues the following warning. $ make […] Compiling IASL out/src/fw/acpi-dsdt.hex out/src/fw/acpi-dsdt.dsl.i 360: Method(IQCR, 1, NotSerialized) { Remark 2120 - ^ Control Method should be made Serialized (due to creation of named objects within) […] ASL Input: out/src/fw/acpi-dsdt.dsl.i - 475 lines, 19181 bytes, 316 keywords AML Output: out/src/fw/acpi-dsdt.aml - 4407 bytes, 159 named objects, 157 executable opcodes Listing File: out/src/fw/acpi-dsdt.lst - 143715 bytes Hex Dump: out/src/fw/acpi-dsdt.hex - 41661 bytes Compilation complete. 0 Errors, 0 Warnings, 1 Remarks, 246 Optimizations […] After changing the parameter from `NotSerialized` to `Serialized`, the remark is indeed gone and there is no size change. The remark was added in ACPICA version 20130517 [1] and gives the following explanation. If a thread blocks within the method for any reason, and another thread enters the method, the method will fail because an attempt will be made to create the same (named) object twice. In this case, issue a remark that the method should be marked serialized. ACPICA BZ 909.
