All SDTs share the same header, and are length bytes long. The signature tells us which SDT this is.

The ACPI Spec (Version 6.2) defines the following SDT signatures: “APIC” - Multiple APIC Descriptor Table (MADT) “BGRT” - Boot Graphics Resource Table “BERT” - Boot Error Record Table “CPEP” - Corrected Platform Error Polling Table “DSDT” - Differentiated System Descriptor Table “ECDT” - Embedded Controller Boot Resources Table “EINJ” - Error Injection Table “ERST” - Error Record Serialization Table “FACP” - Fixed ACPI Description Table (FADT) “FACS” - Firmware ACPI Control Structure “FPDT” - Firmware Performance Data Table “GTDT” - Generic Timer Description Table “HEST” - Hardware Error Source Table “HMAT” - Heterogeneous Memory Attributes Table “MSCT” - Maximum System Characteristics Table “MPST” - Memory Power State Table “NFIT” - NVDIMM Firmware Interface Table “OEMx” - Various OEM-specific tables “PDTT” - Platform Debug Trigger Table “PMTT” - Platform Memory Topology Table “PPTT” - Processor Properties Topology Table “PSDT” - Persistent System Description Table “RASF” - ACPI RAS Feature Table “RSDT” - Root System Descriptor Table “SBST” - Smart Battery Specification Table “SLIT” - System Locality Information Table “SRAT” - System Resource Affinity Table “SSDT” - Secondary System Description Table “XSDT” - eXtended System Descriptor Table

We’ve come across some more ACPI tables in the wild: “WAET” - Windows ACPI Emulated device Table

Implementations

impl SdtHeader[src]

pub fn validate(&self, signature: Signature) -> Result<(), AcpiError>[src]

Check that: a) The signature matches the one given b) The checksum of the SDT

This assumes that the whole SDT is mapped.
