18.5.1.2 Serialization Instruction Entries
Each Serialization Action consists of a series of one or more Serialization Instructions. A
Serialization Instruction represents a primitive operation on an abstracted hardware register
represented by the register region as defined in a Serialization Instruction Entry.
A Serialization Instruction Entry describes a region in a serialization hardware register and the
serialization instruction to be performed on that region. Table 18-336 details the layout of a
Serialization Instruction Entry.
