[Qemu-devel] [PATCH v2 01/31] pc: ACPI BIOS: use enum for defining memory affinity flags |
Date: |
Tue, 20 May 2014 17:15:04 +0200 |
replace magic numbers with enum describing Flags field of
memory affinity in SRAT table.
MemoryAffinityFlags enum will define flags decribed by:
ACPI spec 5.0, "5.2.16.2 Memory Affinity Structure",
"Table 5-69 Flags - Memory Affinity Structure"
