This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and\nVT_RESIZEX ioctl\u0027s. One particular utility, SVGATextMode, expects that\ncon_resize() of the VGA console will always return success even if the\nresulting screen is not compatible with the hardware. However, this\nparticular behavior of the VGA console, as reported in Kernel Bugzilla Bug\n7513, can cause undefined behavior if the user starts with a console size\nlarger than 80x25.\n\nTo work around this problem, add an extra parameter to con_resize(). This\nparameter is ignored by drivers except for vgacon. If this parameter is\nnon-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl\nand vgacon will always return success. If this parameter is zero, vgacon will\nreturn -EINVAL if the requested size is not compatible with the hardware. The\nlatter is the more correct behavior.\n\nWith this change, SVGATextMode should still work correctly while in-kernel and\nstty resize calls can expect correct behavior from vgacon.\n\nSigned-off-by: Antonino Daplas \u003cadaplas@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "394d3af7ba9e67d630c1c6d2ac1d9c11b318b73e", "tree": "7057c8c671e7bc33753830928c82c9c5378cd496", "parents": [ "28ebe4f66beda8f142569d24fe3b168f8a08a6a6" ], "author": { "name": "Krzysztof Halasa", "email": "khc@pm.waw.pl", "time": "Tue Oct 16 01:29:34 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:43:20 2007 -0700" }, "message": "Intel FB: more interlaced mode support\n\nIntel FB: allow odd- and even-field-first in interlaced modes, and\nproper sync to vertical retrace\n\nSigned-off-by: Krzysztof Halasa \u003ckhc@pm.waw.pl\u003e\nCc: \"Antonino A.

It uses a userspace helper (v86d)\nto execute calls to the x86 Video BIOS functions. The driver is not limited\nto any specific arch and whether it works on a given arch or not depends on\nthat arch being supported by the userspace daemon. It has been tested on\nx86_32 and x86_64.\n\nA single BIOS call is represented by an instance of the uvesafb_ktask\nstructure. This structure contains a buffer, a completion struct and a\nuvesafb_task substructure, containing the values of the x86 registers, a flags\nfield and a field indicating the length of the buffer. Whenever a BIOS call\nis made in the driver, uvesafb_exec() builds a message using the uvesafb_task\nsubstructure and the contents of the buffer. This message is then assigned a\nrandom ack number and sent to the userspace daemon using the connector\ninterface.\n\nThe message\u0027s sequence number is used as an index for the uvfb_tasks array,\nwhich provides a mapping from the messages coming from userspace to the\nin-kernel uvesafb_ktask structs.\n\nThe userspace daemon performs the requested operation and sends a reply in the\nform of a uvesafb_task struct and, optionally, a buffer.

One real time group did use it to\naffectively isolate CPUs from any load balancing efforts. They are willing\nto adapt to alternative mechanisms for this, such as someway to manipulate\nthe list of isolated CPUs on a running system. They can do without this\npresent cpu_exclusive based mechanism while we develop an alternative.\n\nThere is a real risk, to the best of my understanding, of users\naccidentally setting up a partitioned scheduler domains, inhibiting desired\nload balancing across all their CPUs, due to the nonobvious (from the\ncpuset perspective) side affects of the cpu_exclusive flag.\n\nFurthermore, since there was no way on a running system to see what one was\ndoing with sched domains, this change will be invisible to any using code.\nUnless they have real insight to the scheduler load balancing choices, they\nwill be unable to detect that this change has been made in the kernel\u0027s\nbehaviour.\n\nInitial discussion on lkml of this patch has generated much comment. My\n(probably controversial) take on that discussion is that it has reached a\nrough concensus that the current cpuset cpu_exclusive mechanism for\ndefining sched domains is borked. There is no concensus on the\nreplacement. But since we can remove this mechanism, and since its\ncontinued presence risks causing unwanted partitioning of the schedulers\nload balancing, we should remove it while we can, as we proceed to work the\nreplacement scheduler domain mechanisms.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Christoph Lameter \u003cclameter@engr.sgi.com\u003e\nCc: Dinakar Guniguntala \u003cdino@in.ibm.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2ed6dc34f9ed39bb8e4c81ea1056f0ba56315841", "tree": "e3f6ca7961f9c4e34453d06e584c0bc98ec630d7", "parents": [ "7589670f37736bcc119ebfbd69aafea6d585d1d4" ], "author": { "name": "Shannon Nelson", "email": "shannon.nelson@intel.com", "time": "Tue Oct 16 01:27:42 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:43:09 2007 -0700" }, "message": "I/OAT: Add DCA services\n\nAdd code to connect to the DCA driver and provide cpu tags for use by\ndrivers that would like to use Direct Cache Access hints.\n\n [Adrian Bunk] Several Kconfig cleanup items\n [Andrew Morten, Chris Leech] Fix for using cpu_physical_id() even when\n\t\t\t built for uni-processor\n\nSigned-off-by: Shannon Nelson \u003cshannon.nelson@intel.com\u003e\nAcked-by: David S.

These are\nperformance critical structures since the per node information has\nto be touched for every alloc and free in a slab.\n\nIn order to place the kmem_cache_cpu structure optimally we put an array\nof pointers to kmem_cache_cpu structs in kmem_cache (similar to SLAB).\n\nHowever, the kmem_cache_cpu structures can now be allocated in a more\nintelligent way.\n\nWe would like to put per cpu structures for the same cpu but different\nslab caches in cachelines together to save space and decrease the cache\nfootprint. However, the slab allocators itself control only allocations\nper node. We set up a simple per cpu array for every processor with\n100 per cpu structures which is usually enough to get them all set up right.\nIf we run out then we fall back to kmalloc_node. This also solves the\nbootstrap problem since we do not have to use slab allocator functions\nearly in boot to get memory for the small per cpu structures.\n\nPro:\n\t- NUMA aware placement improves memory performance\n\t- All global structures in struct kmem_cache become readonly\n\t- Dense packing of per cpu structures reduces cacheline\n\t footprint in SMP and NUMA.\n\t- Potential avoidance of exclusive cacheline fetches\n\t on the free and alloc hotpath since multiple kmem_cache_cpu\n\t structures are in one cacheline.

If objects have a short lifetime and are freed by\na different processor then remote frees back to the slab from which we are\ncurrently allocating are frequent. The cacheline with the page struct needs\nto be repeately acquired in exclusive mode by both the allocating thread and\nthe freeing thread. If this is frequent enough then performance will suffer\nbecause of cacheline bouncing.\n\nThis patchset puts the lockless_freelist pointer in its own cacheline. In\norder to make that happen we introduce a per cpu structure called\nkmem_cache_cpu.\n\nInstead of keeping an array of pointers to page structs we now keep an array\nto a per cpu structure that--among other things--contains the pointer to the\nlockless freelist. The freeing thread can then keep possession of exclusive\naccess to the page struct cacheline while the allocating thread keeps its\nexclusive access to the cacheline containing the per cpu structure.\n\nThis works as long as the allocating cpu is able to service its request\nfrom the lockless freelist. If the lockless freelist runs empty then the\nallocating thread needs to acquire exclusive access to the cacheline with\nthe page struct lock the slab.\n\nThe allocating thread will then check if new objects were freed to the per\ncpu slab. If so it will keep the slab as the cpu slab and continue with the\nrecently remote freed objects. So the allocating thread can take a series\nof just freed remote pages and dish them out again. Ideally allocations\ncould be just recycling objects in the same slab this way which will lead\nto an ideal allocation / remote free pattern.\n\nThe number of objects that can be handled in this way is limited by the\ncapacity of one slab. Increasing slab size via slub_min_objects/\nslub_max_order may increase the number of objects and therefore performance.\n\nIf the allocating thread runs out of objects and finds that no objects were\nput back by the remote processor then it will retrieve a new slab (from the\npartial lists or from the page allocator) and start with a whole\nnew set of objects while the remote thread may still be freeing objects to\nthe old cpu slab. This may then repeat until the new slab is also exhausted.\nIf remote freeing has freed objects in the earlier slab then that earlier\nslab will now be on the partial freelist and the allocating thread will\npick that slab next for allocation. So the loop is extended. However,\nboth threads need to take the list_lock to make the swizzling via\nthe partial list happen.\n\nIt is likely that this kind of scheme will keep the objects being passed\naround to a small set that can be kept in the cpu caches leading to increased\nperformance.\n\nMore code cleanups become possible:\n\n- Instead of passing a cpu we can now pass a kmem_cache_cpu structure around.\n Allows reducing the number of parameters to various functions.\n- Can define a new node_match() function for NUMA to encapsulate locality\n checks.\n\nEffect on allocations:\n\nCachelines touched before this patch:\n\n\tWrite:\tpage cache struct and first cacheline of object\n\nCachelines touched after this patch:\n\n\tWrite:\tkmem_cache_cpu cacheline and first cacheline of object\n\tRead: page cache struct (but see later patch that avoids touching\n\t\tthat cacheline)\n\nThe handling when the lockless alloc list runs empty gets to be a bit more\ncomplicated since another cacheline has now to be written to. But that is\nhalfway out of the hot path.\n\nEffect on freeing:\n\nCachelines touched before this patch:\n\n\tWrite: page_struct and first cacheline of object\n\nCachelines touched after this patch depending on how we free:\n\n Write(to cpu_slab):\tkmem_cache_cpu struct and first cacheline of object\n Write(to other):\tpage struct and first cacheline of object\n\n Read(to cpu_slab):\tpage struct to id slab etc. (but see later patch that\n \t\t\tavoids touching the page struct on free)\n Read(to other):\tcpu local kmem_cache_cpu struct to verify its not\n \t\t\tthe cpu slab.\n\nSummary:\n\nPro:\n\t- Distinct cachelines so that concurrent remote frees and local\n\t allocs on a cpuslab can occur without cacheline bouncing.\n\t- Avoids potential bouncing cachelines because of neighboring\n\t per cpu pointer updates in kmem_cache\u0027s cpu_slab structure since\n\t it now grows to a cacheline (Therefore remove the comment\n\t that talks about that concern).\n\nCons:\n\t- Freeing objects now requires the reading of one additional\n\t cacheline. That can be mitigated for some cases by the following\n\t patches but its not possible to completely eliminate these\n\t references.\n\n\t- Memory usage grows slightly.\n\n\tThe size of each per cpu object is blown up from one word\n\t(pointing to the page_struct) to one cacheline with various data.\n\tSo this is NR_CPUS*NR_SLABS*L1_BYTES more memory use.

When an administrator sets the\nreserve at 16384 at boot time, it tends to be the same MAX_ORDER blocks\nthat remain free. This allows the occasional high atomic allocation to\nsucceed up until the point the blocks are split. In practice, it is\ndifficult to split these blocks but when they do split, the benefit of\nhaving min_free_kbytes for contiguous blocks disappears. Additionally,\nincreasing min_free_kbytes once the system has been running for some time\nhas no guarantee of creating contiguous blocks.\n\nOn the other hand, CONFIG_PAGE_GROUP_BY_MOBILITY favours splitting large\nblocks when there are no free pages of the appropriate type available. A\nside-effect of this is that all blocks in memory tends to be used up and\nthe contiguous free blocks from boot time are not preserved like in the\nvanilla allocator. This can cause a problem if a new caller is unwilling\nto reclaim or does not reclaim for long enough.\n\nA failure scenario was found for a wireless network device allocating\norder-1 atomic allocations but the allocations were not intense or frequent\nenough for a whole block of pages to be preserved for MIGRATE_HIGHALLOC.\nThis was reproduced on a desktop by booting with mem\u003d256mb, forcing the\ndriver to allocate at order-1, running a bittorrent client (downloading a\ndebian ISO) and building a kernel with -j2.\n\nThis patch addresses the problem on the desktop machine booted with\nmem\u003d256mb. It works by setting aside a reserve of MAX_ORDER_NR_PAGES\nblocks, the number of which depends on the value of min_free_kbytes. These\nblocks are only fallen back to when there is no other free pages. Then the\nsmallest possible page is used just like the normal buddy allocator instead\nof the largest possible page to preserve contiguous pages The pages in free\nlists in the reserve blocks are never taken for another migrate type. The\nresults is that even if min_free_kbytes is set to a low value, contiguous\nblocks will be preserved in the MIGRATE_RESERVE blocks.\n\nThis works better than the vanilla allocator because if min_free_kbytes is\nincreased, a new reserve block will be chosen based on the location of\nreclaimable pages and the block will free up as contiguous pages. In the\nvanilla allocator, no effort is made to target a block of pages to free as\ncontiguous pages and min_free_kbytes pages are scattered randomly.\n\nThis effect has been observed on the test machine. min_free_kbytes was set\ninitially low but it was kept as a contiguous free block within\nMIGRATE_RESERVE. min_free_kbytes was then set to a higher value and over a\nperiod of time, the free blocks were within the reserve and coalescing.\nHow long it takes to free up depends on how quickly LRU is rotating.\nAmusingly, this means that more activity will free the blocks faster.\n\nThis mechanism potentially replaces MIGRATE_HIGHALLOC as it may be more\neffective than grouping contiguous free pages together. It all depends on\nwhether the number of active atomic high allocations exceeds\nmin_free_kbytes or not. If the number of active allocations exceeds\nmin_free_kbytes, it\u0027s worth it but maybe in that situation, min_free_kbytes\nshould be set higher. Once there are no more reports of allocation\nfailures, a patch will be submitted that backs out MIGRATE_HIGHALLOC and\nsee if the reports stay missing.\n\nCredit to Mariusz Kozlowski for discovering the problem, describing the\nfailure scenario and testing patches and scenarios.\n\n[akpm@linux-foundation.org: cleanups]\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5c0e3066474b57c56ff0d88ca31d95bd14232fee", "tree": "90c963c62891db4a9039e84e615c01408b09c845", "parents": [ "46dafbca2bba811665b01d8cedf911204820623c" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Tue Oct 16 01:25:56 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:43:00 2007 -0700" }, "message": "Fix corruption of memmap on IA64 SPARSEMEM when mem_section is not a power of 2\n\nThere are problems in the use of SPARSEMEM and pageblock flags that causes\nproblems on ia64.\n\nThe first part of the problem is that units are incorrect in\nSECTION_BLOCKFLAGS_BITS computation.

When pages are migrated (or reclaimed under\nmemory pressure), large contiguous pages will be freed.\n\nThis patch works by categorising allocations by their ability to migrate;\n\nMovable - The pages may be moved with the page migration mechanism. These are\n\tgenerally userspace pages.\n\nReclaimable - These are allocations for some kernel caches that are\n\treclaimable or allocations that are known to be very short-lived.\n\nUnmovable - These are pages that are allocated by the kernel that\n\tare not trivially reclaimed. For example, the memory allocated for a\n\tloaded module would be in this category. By default, allocations are\n\tconsidered to be of this type\n\nHighAtomic - These are high-order allocations belonging to callers that\n\tcannot sleep or perform any IO. In practice, this is restricted to\n\tjumbo frame allocation for network receive. It is assumed that the\n\tallocations are short-lived\n\nInstead of having one MAX_ORDER-sized array of free lists in struct free_area,\nthere is one for each type of reclaimability. Once a 2^MAX_ORDER block of\npages is split for a type of allocation, it is added to the free-lists for\nthat type, in effect reserving it. Hence, over time, pages of the different\ntypes can be clustered together.\n\nWhen the preferred freelists are expired, the largest possible block is taken\nfrom an alternative list. Buddies that are split from that large block are\nplaced on the preferred allocation-type freelists to mitigate fragmentation.\n\nThis implementation gives best-effort for low fragmentation in all zones.\nIdeally, min_free_kbytes needs to be set to a value equal to 4 * (1 \u003c\u003c\n(MAX_ORDER-1)) pages in most cases. This would be 16384 on x86 and x86_64 for\nexample.\n\nOur tests show that about 60-70% of physical memory can be allocated on a\ndesktop after a few days uptime. In benchmarks and stress tests, we are\nfinding that 80% of memory is available as contiguous blocks at the end of the\ntest. To compare, a standard kernel was getting \u003c 1% of memory as large pages\non a desktop and about 8-12% of memory as large pages at the end of stress\ntests.\n\nFollowing this email are 12 patches that implement thie page grouping feature.\n The first patch introduces a mechanism for storing flags related to a whole\nblock of pages. Then allocations are split between movable and all other\nallocations. Following that are patches to deal with per-cpu pages and make\nthe mechanism configurable. The next patch moves free pages between lists\nwhen partially allocated blocks are used for pages of another migrate type.\nThe second last patch groups reclaimable kernel allocations such as inode\ncaches together. The final patch related to groupings keeps high-order atomic\nallocations.\n\nThe last two patches are more concerned with control of fragmentation. The\nsecond last patch biases placement of non-movable allocations towards the\nstart of memory. This is with a view of supporting memory hot-remove of DIMMs\nwith higher PFNs in the future. The biasing could be enforced a lot heavier\nbut it would cost. The last patch agressively clusters reclaimable pages like\ninode caches together.\n\nThe fragmentation reduction strategy needs to track if pages within a block\ncan be moved or reclaimed so that pages are freed to the appropriate list.\nThis patch adds a bitmap for flags affecting a whole a MAX_ORDER block of\npages.\n\nIn non-SPARSEMEM configurations, the bitmap is stored in the struct zone and\nallocated during initialisation. SPARSEMEM statically allocates the bitmap in\na struct mem_section so that bitmaps do not have to be resized during memory\nhotadd. This wastes a small amount of memory per unused section (usually\nsizeof(unsigned long)) but the complexity of dynamically allocating the memory\nis quite high.\n\nAdditional credit to Andy Whitcroft who reviewed up an earlier implementation\nof the mechanism an suggested how to make it a *lot* cleaner.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "954ffcb35f5aca428661d29b96c4eee82b3c19cd" }
