Maximum System Characteristics Table (MSCT)

This section describes the format of the Maximum System Characteristic Table (MSCT), which provides OSPM with information characteristics of a system’s maximum topology capabilities. If the system maximum topology is not known up front at boot time, then this table is not present. OSPM will use information provided by the MSCT only when the System Resource Affinity Table (SRAT) exists. The MSCT must contain all proximity and clock domains defined in the SRAT.

Fields

header: SDTHeader

• Signature - “MSCT”

offset_prox_dom_info: u32

Offset in bytes to the Proximity Domain Information Structure table entry.

max_number_of_proximity_domains: u32

Indicates the maximum number of Proximity Domains ever possible in the system.

The number reported in this field is (maximum domains - 1). For example if there are 0x10000 possible domains in the system, this field would report 0xFFFF.

max_number_of_clock_domains: u32

Indicates the maximum number of Clock Domains ever possible in the system.

The number reported in this field is (maximum domains - 1).

max_physical_address: u64

Indicates the maximum Physical Address ever possible in the system.

Note: this is the top of the reachable physical address.

Implementations

impl MaximumSystemCharacteristicsTable

pub const fn proximity_domain_information( &self, ) -> &[MaximumProximityDomainInformation]

JJ’s Note: The specs say that this field is located somewhere depending on the offset field in the structure (not aligned with the structure at all), which is why I provided this.
