* [PATCH] pgdat allocation and update for ia64 of memory hotplug: allocate ↵Yasunori Goto2006-06-27
| | | | | | | | | | | | pgdat and per node data This is a patch to allocate pgdat and per node data area for ia64. The size for them can be calculated by compute_pernodesize().

* [PATCH] pgdat allocation and update for ia64 of memory hotplug: update pgdat ↵Yasunori Goto2006-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | address array This is to refresh node_data[] array for ia64. As I mentioned previous patches, ia64 has copies of information of pgdat address array on each node as per node data. At v2 of node_add, this function used stop_machine_run() to update them. (I wished that they were copied safety as much as possible.) But, in this patch, this arrays are just copied simply, and set node_online_map bit after completion of pgdat initialization. So, kernel must touch NODE_DATA() macro after checking node_online_map(). (Current code has already done it.) This is more simple way for just hot-add..... Note : It will be problem when hot-remove will occur, because, even if online_map bit is set, kernel may touch NODE_DATA() due to race condition. :-( Signed-off-by: Yasunori Goto <y-goto@jp.fujitsu.com> Cc: "Luck, Tony" <tony.luck@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] pgdat allocation and update for ia64 of memory hotplug: hold pgdat ↵Yasunori Goto2006-06-27
| | | | | | | | | | | | | | | | address at system running This is a preparatory patch to make common code for updating of NODE_DATA() of ia64 between boottime and hotplug. Current code remembers pgdat address in mem_data which is used at just boot time. But its information can be used at hotplug time by moving to global value. The next patch uses this array.

* [PATCH] Register sysfs file for hotplugged new nodeYasunori Goto2006-06-27
| | | | | | | | | | | | | | | When new node becomes enable by hot-add, new sysfs file must be created for new node. So, if new node is enabled by add_memory(), register_one_node() is called to create it. In addition, I386's arch_register_node() and a part of register_nodes() of powerpc are consolidated to register_one_node() as a generic_code(). This is tested by Tiger4(IPF) with node hot-plug emulation.

* [PATCH] catch valid mem range at onlining memoryKAMEZAWA Hiroyuki2006-06-27
| | | | | | | | | | | | | | | | | | This patch allows hot-add memory which is not aligned to section. Now, hot-added memory has to be aligned to section size. Considering big section sized archs, this is not useful. When hot-added memory is registerd as iomem resoruce by iomem resource patch, we can make use of that information to detect valid memory range. Note: With this, not-aligned memory can be registerd. To allow hot-add memory with holes, we have to do more work around add_memory(). (It doesn't allows add memory to already existing mem section.)

* [PATCH] pgdat allocation for new node add (call pgdat allocation)Yasunori Goto2006-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add node-hot-add support to add_memory(). node hotadd uses this sequence. 1. allocate pgdat. 2. refresh NODE_DATA() 3. call free_area_init_node() to initialize 4. create sysfs entry 5. add memory (old add_memory()) 6. set node online 7. run kswapd for new node. (8). update zonelist after pages are onlined. (This is already merged in -mm due to update phase is difference.) Note: To make common function as much as possible, there is 2 changes from v2. - The old add_memory(), which is defiend by each archs, is renamed to arch_add_memory(). New add_memory becomes caller of arch dependent function as a common code. - This patch changes add_memory()'s interface From: add_memory(start, end) TO : add_memory(nid, start, end). It was cause of similar code that finding node id from physical address is inside of old add_memory() on each arch. In addition, acpi memory hotplug driver can find node id easier. In v2, it must walk DSDT'S _CRS by matching physical address to get the handle of its memory device, then get _PXM and node id. Because input is just physical address. However, in v3, the acpi driver can use handle to get _PXM and node id for the new memory device. It can pass just node id to add_memory(). Fix interface of arch_add_memory() is in next patche.

* [PATCH] pgdat allocation for new node add (generic alloc node_data)Yasunori Goto2006-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For node hotplug, basically we have to allocate new pgdat. But, there are several types of implementations of pgdat. 1. Allocate only pgdat. This style allocate only pgdat area. And its address is recorded in node_data[]. It is most popular style. 2. Static array of pgdat In this case, all of pgdats are static array. Some archs use this style. 3. Allocate not only pgdat, but also per node data. To increase performance, each node has copy of some data as a per node data. So, this area must be allocated too. Ia64 is this style. Ia64 has the copies of node_data[] array on each per node data to increase performance. In this series of patches, treat (1) as generic arch. generic archs can use generic function. (2) and (3) should have its own if necessary. This patch defines pgdat allocator. Updating NODE_DATA() macro function is in other patch.

* [PATCH] pgdat allocation for new node add (get node id by acpi)Yasunori Goto2006-06-27
| | | | | | | | | | | | | | | | | This is to find node id from acpi's handle of memory_device in DSDT. _PXM for the new node can be found by acpi_get_pxm() by using new memory's handle. So, node id can be found by pxm_to_nid_map[]. This patch becomes simpler than v2 of node hot-add patch. Because old add_memory() function doesn't have node id parameter. So, kernel must find its handle by physical address via DSDT again. But, v3 just give node id to add_memory() now.

* [PATCH] pgdat allocation for new node add (specify node id)Yasunori Goto2006-06-27
| | | | | | | | | | | | | | | | Change the name of old add_memory() to arch_add_memory. And use node id to get pgdat for the node at NODE_DATA(). Note: Powerpc's old add_memory() is defined as __devinit. However, add_memory() is usually called only after bootup. I suppose it may be redundant. But, I'm not well known about powerpc. So, I keep it. (But, __meminit is better at least.)

* [PATCH] Catch notification of memory add event of ACPI via container driver. ↵Yasunori Goto2006-06-27
| | | | | | | | | | | | | | | | | | | | | (avoid redundant call add_memory) When acpi_memory_device_init() is called at boottime to register struct memory acpi_memory_device, acpi_bus_add() are called via acpi_driver_attach(). But it also calls ops->start() function. It is called even if the memory blocks are initialized at early boottime. In this case add_memory() return -EEXIST, and the memory blocks becomes INVALID state even if it is normal. This is patch to avoid calling add_memory() for already available memory.

* [PATCH] Catch notification of memory add event of ACPI via container driver. ↵Yasunori Goto2006-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (register start func for memory device) This is a patch to call add_memroy() when notify reaches for new node's add event. When new node is added, notify of ACPI reaches container device which means the node. Container device driver calls acpi_bus_scan() to find and add belonging devices (which means cpu, memory and so on). Its function calls add and start function of belonging devices's driver. Howevever, current memory hotplug driver just register add function to create sysfs file for its memory. But, acpi_memory_enable_device() is not called because it is considered just the case that notify reaches memory device directly. So, if notify reaches container device nothing can call add_memory(). This is a patch to create start function which calls add_memory(). add_memory() can be called by this when notify reaches container device.

* [PATCH] acpi memory hotplug cannot manage _CRS with plural resourecesKAMEZAWA Hiroyuki2006-06-27
| | | | | | | | | | | | | | | | | | | | | | | | Current acpi memory hotplug just looks into the first entry of resources in _CRS. But, _CRS can contain plural resources. So, if _CRS contains plural resoureces, acpi memory hot add cannot add all memory. With this patch, acpi memory hotplug can deal with Memory Device, whose _CRS contains plural resources. Tested on ia64 memory hotplug test envrionment (not emulation, uses alpha version firmware which supports dynamic reconfiguration of NUMA.) Note: Microsoft's Windows Server 2003 requires big (>4G)resoureces to be divided into small (<4G) resources. looks crazy, but not invalid. (See http://www.microsoft.com/whdc/system/pnppwr/hotadd/hotaddmem.mspx) For this reason, a firmware vendor who supports Windows writes plural resources in a _CRS even if they are contiguous.
