Bruce Cran reported the following issue:
With iasl version 20150410-64 building OvmfX64 (using OvmfPkg/build.sh
-a X64 -t GCC49 -b RELEASE) results in a couple of warnings about
methods that should be serialized:
.../OvmfPkg/AcpiTables/AcpiTables/OUTPUT/./Dsdt.iiii
95: Method (_CRS, 0) {
Remark 2120 - Control Method should be made Serialized ^ (due to
creation of named objects within)
.../OvmfPkg/AcpiTables/AcpiTables/OUTPUT/./Dsdt.iiii
235: Method (PCRS, 1, NotSerialized) {
Remark 2120 - Control Method should be made Serialized ^ (due to
creation of named objects within)
The ACPI 6.0 spec justifies the above warnings in "19.6.82 Method (Declare
Control Method)":
[...] The serialize rule can be used to prevent reentering of a method.
This is especially useful if the method creates namespace objects.
Without the serialize rule, the reentering of a method will fail when it
attempts to create the same namespace object. [...]
