This patch provides generic discontiguous memory support for the i386 numa architecture. The patch also provides supports for the ia32 IBM NUMA-Q hardware platform. John Stultz also has added support for the x440 hardware, but now it's mine. This will be posted separately at a later date. A version of this patch has been accepted into the v2.5 tree starting with 2.5.34.
This patch depends on the paddr->pfn patch that I just sent out.
Assumptions made:
- that the first node has at least 900Mb of memory
Testing done:
- single proc desktop pc (CONFIG_X86_NUMAQ is not set) - 4 proc SMP system (CONFIG_X86_NUMAQ is not set) - 4 proc SMP system (CONFIG_X86_NUMAQ is not set, CONFIG_HIGHMEM=64GB) - 16 proc NUMA box with 4GB memory (CONFIG_X86_NUMAQ=y, CONFIG_NUMA is not set) - 16 proc NUMA box with 4GB memory (CONFIG_X86_NUMAQ=y, CONFIG_NUMA is not set, CONFIG_HIGHMEM=64GB) - 16 proc NUMA box with 4GB memory (CONFIG_X86_NUMAQ=y, CONFIG_NUMA=y) - 16 proc NUMA box with 4GB memory (CONFIG_X86_NUMAQ=y, CONFIG_NUMA=y, CONFIG_HIGHMEM=64GB) - 8 proc NUMA box with 8GB memeory (CONFIG_X86_NUMAQ=y, CONFIG_NUMA=y, CONFIG_HIGHMEM=64GB) - 16 proc NUMA box with 16GB memory (CONFIG_X86_NUMAQ=y, CONFIG_NUMA=y, CONFIG_HIGHMEM=64GB)
Any and all feedback regarding this patch is greatly appreciated.
Thanks, Pat
