[PATCH] hw/riscv/virt-acpi-build.c: Add SRAT and SLIT ACPI tables
Posted by Haibo Xu 10 months ago
Enable ACPI NUMA support by adding the following 2 ACPI tables:
SRAT: provides the association for memory/Harts and Proximity Domains
SLIT: provides the relative distance between Proximity Domains

The SRAT RINTC Affinity Structure definition[1] was based on the recently
approved ACPI CodeFirst ECR[2].
