| |
Hi.
This patch set is to unify mapping from pxm to node id ver.4. I posted patches for config of NODES_SHIFT. So, MAX_PXM_DOMAIN is just defined by MAX_NUMNODES. (But, old pxm's spec was 8 bit. So, if MAX_NUMNODES is 256 or smaller, then I use 256 for it.)
This patches are for 2.6.16-git16. I tested them on ia64(Tiger4) with node emulation.
Please apply.
------------------------ Change log from ver.3 - The patch for configuration of NODES_SHIFT is divided to other post. MAX_PXM_DOMAIN is defined by MAX_NUMNODES.
Change log from ver.2 - update for 2.6.16-git14. - definition of pxm was changed from u8 to int. Pxm can be over 256. - CONFIG_NR_NODES is defined to configure MAX_PXM_DOMAINS. - redundant call of pxm_bit_set() is removed at acpi_numa_arch_fixup() of ia64 like followings. if (pxm_bit_test(i)) { : pxm_bit_set(i); <---------------------- !!! : }
Change log from ver.1 - Fix old map from HP and SGI's code by Bob Picco-san. - Remove MAX_PXM_DOMAINS from asm-ia64/acpi.h. It is already defined at include/acpi/acpi_numa.h. - Fix return code of setup_node() at arch/x86_64/mm/srat.c - Fix ACPI_NUMA config for i386 by Andy Witcroft-san. - Define dummy functions for i386's compile error. - Remove garbage nid_to_pxm_map from acpi20_parse_srat() at arch/i386/kernel/srat.c
---------------------------------- Description.
This patch is to unify mapping from pxm to node id. In current code, i386, x86-64, and ia64 have its mapping by each own code. But PXM is defined by ACPI and node id is used generically. So, I think there is no reason to define it on each arch's code. This mapping should be written at drivers/acpi/numa.c as a common code.
