Support for NUMA in x86_32 architecture
I am trying to enable NUMA support in x86_32 architecture since few days. I enabled options for NUMA while doing menuconfig. But what I get from my boot messages (dmesg) is '>could not find any ACPI SRAT memory areas'. I searched kernel code a little and found that the SRAT is needed for NUMA node geometry. Further, SRAT is loaded from Root System Description Table (RSDT), which is obtained from BIOS.
Since SRAT is loaded at boot time, it seems that no hardware support for SRAT is available for my X86_32 machine.
Can anybody suggest a way out of this problem and give me a hack by which i can enable SRAT on my machine?
