It is a new implementation replacing the\nold-fashioned driver currently present in the linux-mips.org tree. It\nsupports all the usual features one would expect from a(n asynchronous)\nserial driver, including modem line control (as far as hardware supports it\n-- there is edge detection logic missing from the DCD and RI lines and the\ndriver does not implement polling of these lines at the moment), the serial\nconsole, BREAK transmission and reception, including the magic SysRq. The\nreceive FIFO threshold is not maintained though.\n\nThe driver was tested with a SWARM board which uses a BCM1250 SOC (which is\ndual MIPS64 CMP) and has both ports of the single DUART implemented wired\nexternally. Both were tested. Testing included using the ports as\nterminal lines at 1200bps (which is the ports minimum), 115200bps and a\ncouple of random speeds inbetween. The modem lines were verified to\noperate correctly. No testing was performed with a use as a network\ninterface, like with SLIP or PPP.\n\nSigned-off-by: Maciej W.

There are no zeroing allocator functions for NUMA node\nplacement (kmalloc_node, kmem_cache_alloc_node). The zeroing allocations are\nonly provided for default allocs (kzalloc, kmem_cache_zalloc_node).\n__GFP_ZERO will make zeroing universally available and does not require any\naddititional functions.\n\nSo add the necessary logic to all slab allocators to support __GFP_ZERO.\n\nThe code is added to the hot path. The gfp flags are on the stack and so the\ncacheline is readily available for checking if we want a zeroed object.\n\nZeroing while allocating is now a frequent operation and we seem to be\ngradually approaching a 1-1 parity between zeroing and not zeroing allocs.\nThe current tree has 3476 uses of kmalloc vs 2731 uses of kzalloc.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nAcked-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6cb8f91320d3e720351c21741da795fed580b21b", "tree": "c9f73c8b82cd0f6c534939b8b9f36e8615b0ab2d", "parents": [ "ef2ad80c7d255ed0449eda947c2d700635b7e0f5" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Tue Jul 17 04:03:22 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Jul 17 10:23:01 2007 -0700" }, "message": "Slab allocators: consistent ZERO_SIZE_PTR support and NULL result semantics\n\nDefine ZERO_OR_NULL_PTR macro to be able to remove the checks from the\nallocators.

The current\nreclaim algorithm targets pages in LRU order, which is great for fairness at\norder-0 but highly unsuitable if you desire pages at higher orders. To get\npages of higher order we must shoot down a very high proportion of memory;\n\u003e95% in a lot of cases.\n\nThis patch set adds a lumpy reclaim algorithm to the allocator. It targets\ngroups of pages at the specified order anchored at the end of the active and\ninactive lists. This encourages groups of pages at the requested orders to\nmove from active to inactive, and active to free lists. This behaviour is\nonly triggered out of direct reclaim when higher order pages have been\nrequested.\n\nThis patch set is particularly effective when utilised with an\nanti-fragmentation scheme which groups pages of similar reclaimability\ntogether.\n\nThis patch set is based on Peter Zijlstra\u0027s lumpy reclaim V2 patch which forms\nthe foundation.

Testing on a desktop machine with 2GB\n of RAM showed that growing the hugepage pool with ZONE_MOVABLE on it\u0027s own\n was very slow as the success rate was quite low. Without lumpy-reclaim,\n each attempt to grow the pool by 100 pages would yield 1 or 2 hugepages.\n With lumpy-reclaim, getting 40 to 70 hugepages on each attempt was typical.\n\n[akpm@osdl.org: ia64 pfn_to_nid fixes and loop cleanup]\n[bunk@stusta.de: static declarations for internal functions]\n[a.p.zijlstra@chello.nl: initial lumpy V2 implementation]\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Bob Picco \u003cbob.picco@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "7e63efef857575320fb413fbc3d0ee704b72845f" }
