Hello, This set of 2 patches make Iwamoto-san's memory hotplug prototype correspond to an IPF NUMA machines. The patch is against linux 2.6.5 and works with Iwamoto-san's memory hotplug patch. I don't have an IPF NUMA machine. So, I tested on Tiger4 (intel's IPF machine) with NUMA node in emulation. Changes from Iwamoto-san's patches are: - Using SRAT for NUMA node. - Structures of all nodes are initialized at boot. In Iwamoto-san's patch, node0 is initialized at boot, and after boot, all nodes except node0 are initialized by hot-add operation. Patch Details: - Patch(1/2) memory hotplug prototype for ia64 The main patch. - Patch(2/2) NUMA node emulation To emulate NUMA node on non-NUMA machines. Remainder items: The following items are being made. - Support of HotAdd function. - Correspond to ACPI's SLIT. So, it does not use find_next_best_node() function (mm/page_alloc.c) which added to linux 2.6.5. - Support of hugetlbpage. How to apply: 1) First of all, apply Iwamoto-san's patches. 2) Apply this set of patches. Thank you, Fumihiro Terasawa. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
