| Thread-topic: | [PATCH][VTD] IO NUMA support |
This patch adds VT-d RHSA processing for IO NUMA support. The basic idea is to parse ACPI RHSA structure to obtain VT-d HW to proximity domain mapping. This mapping is then used when allocating pages for Vt-d HW data structures. Signed-off-by: Allen Kay allen.m.kay@xxxxxxxxx
