| |
Hello.
I'll post newest patches for memory hotadd as V2. In this patch, pgdat is allocated when new node is comming. To initialize pgdat and zones, a set of patches are necessary. - to call memory_hotplug code from acpi container driver. - to allcate and initialize pgdat, zone, zonelist. - to initialize node_data[] array (ia64) - to register sysfs file for new node. This patch set is not only for ia64 but also for x86-64.
Note: - kmalloc is used for pgdat allocation in this version. So, even if pgdat is allocated, it will be allocated on the other node. This is only to simplify patches a bit. :-P
This patches are for 2.6.16-rc3-mm1.
Followings are updates. - update for 2.6.16-rc3-mm1. - not only ia64, This is tested on x86_64 with NUMA emulation too. :-) - wait_table_size() allcation is changed. - Take max size as much as possible. - Change using GFP_ATOMIC. It is inside of zone_init_lock. (Warining message of might_sleep() is very well.) - stop_machine_run(build_zonelists) is move to outside of lock. - pgdat_insert() is moved to generic code to be used by x86_64. - add decision of ZONE_DMA32 or ZONE_NORMAL to x86_64's add_memory(). - Make a separated patch to change from __init to __meminit. - Fix some typo
Please comment.
