It is made of two levels: a template that consists of\nthe core copy code and separate files that define macros to be used with\nthe core code depending on the type of copy needed. This allows for best\nperformances while sharing the same core for implementing memcpy(),\ncopy_from_user() and copy_to_user() for instance.\n\nTwo reasons for this work:\n\n1) the current copy_to_user/copy_from_user implementation assumes no\n task switch will ever occur in the middle of each copied page making\n it completely unsafe with CONFIG_PREEMPT\u003dy.\n\n2) current copy implementations are measurably suboptimal and optimizing\n different implementations separately is a pain and more opportunities\n for bugs.\n\nThe reason for (1) is the fact that copy inside user pages are performed\nwith the ldm instruction which has no mean for testing user protections\nand could possibly race with process preemption bypassing the COW mechanism\nfor example. This is a longstanding issue that we said ought to be fixed\nfor about two years now. The solution is to substitute those ldm insns\nwith a series of ldrt or strt insns to enforce user memory protection.\nAt least on StrongARM and XScale cores the ldm is not faster than the\nequivalent ldr/str insns with a warm i-cache so there is no measurable\nperformance degradation with that change. The fact that the copy code is\na template makes it pretty easy to reuse the same core code as for memcpy\nand benefit from the same performance optimizations.\n\nNow (2) is best demonstrated with actual throughput measurements.\nFirst, here is a summary of memcopy tests performed on a StrongARM core:\n\n\tPTR alignment\tbuffer size\tkernel version\tthis version\n\t------------------------------------------------------------\n\t aligned\t 32\t\t 59.73\t\t107.43\n\tunaligned\t 32\t\t 61.31\t\t 74.72\n\t aligned\t 100\t\t132.47\t\t136.15\n\tunaligned\t 100\t \t103.84\t\t123.76\n\t aligned\t 4096\t\t130.67\t\t130.80\n\tunaligned\t 4096\t \t130.68\t\t130.64\n\t aligned\t1048576\t\t 68.03\t\t68.18\n\tunaligned\t1048576\t\t 68.03\t\t68.18\n\nThe buffer size is in bytes and the measured speed in MB/s. The copy\nwas performed repeatedly with given buffer and throughput averaged over\n3 seconds.\n\nHere we can see that the current kernel version has a higher entry cost\nthat shows up with small buffers. As buffer size grows both implementation\nconverge to the same throughput.\n\nNow here\u0027s the exact same test performed on an XScale core (PXA255):\n\n\tPTR alignment\tbuffer size\tkernel version\tthis version\n\t------------------------------------------------------------\n\t aligned\t 32\t\t 46.99\t\t 77.58\n\tunaligned\t 32\t\t 53.61\t\t 59.59\n\t aligned\t 100\t\t107.19\t\t136.59\n\tunaligned\t 100\t\t 83.61\t\t 97.58\n\t aligned\t 4096\t\t129.13\t\t129.98\n\tunaligned\t 4096\t\t128.36\t\t128.53\n\t aligned\t1048576\t\t 53.76\t\t 59.41\n\tunaligned\t1048576\t\t 33.67\t\t 56.96\n\nAgain we can see the entry setup cost being higher for the current kernel\nbefore getting to the main copy loop. Then throughput results converge\nas long as the buffer remains in the cache. Then the 1MB case shows more\ndifferences probably due to better pld placement and/or less instruction\ninterlocks in this proposed implementation.\n\nDisclaimer: The PXA system was running with slower clocks than the\nStrongARM system so trying to infer any conclusion by comparing those\nseparate sets of results side by side would be completely inappropriate.\n\nSo... What this patch does is to replace both memcpy and memmove with\nan implementation based on the provided copy code template. The memmove\ncode is kept separate since it is used only if the memory areas involved\ndo overlap in which case the code is a transposition of the template but\nwith the copy occurring in the opposite direction (trying to fit that\nmode into the template turned it into a mess not worth it for memmove\nalone). And obviously both memcpy and memmove were tested with all kinds\nof pointer alignments and buffer sizes to exercise all code paths for\ncorrectness.\n\nThe next patch will provide the now trivial replacement implementation\ncopy_to_user and copy_from_user.\n\nSigned-off-by: Nicolas Pitre \u003cnico@cam.org\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "a0c6fdb987860e6c7f9b8e57439ca2703f462578", "tree": "4709f4675f3e0fb19016c1245c467408dde36206", "parents": [ "85eb226c446a017996859093cbfb5d3ae2c2117a" ], "author": { "name": "Nicolas Pitre", "email": "nico@cam.org", "time": "Tue Nov 01 19:52:22 2005 +0000" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Tue Nov 01 19:52:22 2005 +0000" }, "message": "[ARM] 2946/2: split --arch_clear_user() out of lib/uaccess.S\n\nPatch from Nicolas Pitre\n\nRequired for future enhancement patches.\n\nSigned-off-by: Nicolas Pitre \u003cnico@cam.org\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "85eb226c446a017996859093cbfb5d3ae2c2117a", "tree": "383325e8da1f589ade1236017df896fb06bfab14", "parents": [ "4ebc3364de368c92138e740f6c9050c93a2f0c3c" ], "author": { "name": "David Brownell", "email": "david-b@pacbell.net", "time": "Tue Nov 01 19:44:30 2005 +0000" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Tue Nov 01 19:44:30 2005 +0000" }, "message": "[ARM] 3078/1: lubbock platform updates, mostly mmc detection\n\nPatch from David Brownell\n\nLubbock updates:\n\n * Provide an address for the SMC91x chip that doesn\u0027t generate\n a boot-time warning (matching the EEPROM).\n\n * Update MMC support to (a) detect card insert/remove, and\n (b) report the readonly switch setting for SD cards.\n\nPreviously, MMC/SD cards had to be present at boot time else they\ncouldn\u0027t be detected.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "e838ffc2e5c9afa81451cf21dcd3f3246e2adcd2", "tree": "7b4c3be7ece370d717b31de7356b2820cf2d4706", "parents": [ "fa87cedd4e89ea29bda622d5cd6dbf19a915fc40" ], "author": { "name": "Ben Dooks", "email": "ben-linux@fluff.org", "time": "Tue Nov 01 19:44:28 2005 +0000" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Tue Nov 01 19:44:28 2005 +0000" }, "message": "[ARM] 3071/1: RX3715 -

This can\u0027t\nbe done with a split page_table_lock (and we\u0027ve already taken the lowest lock\nin the hierarchy here): so we\u0027ll have to disable split on arm, unless\nCONFIG_CPU_CACHE_VIPT to ensures adjust_pte never used.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "60ec5585496871345c1a8113d7b60ed9d9474866", "tree": "172df570995ec777ca2a271dda7e3fcbb2dc5acb", "parents": [ "deceb6cd17e6dfafe4c4f81b1b4153bc41b2cb70" ], "author": { "name": "Hugh Dickins", "email": "hugh@veritas.com", "time": "Sat Oct 29 18:16:34 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Oct 29 21:40:41 2005 -0700" }, "message": "[PATCH] mm: i386 sh sh64 ready for split ptlock\n\nUse pte_offset_map_lock, instead of pte_offset_map (or inappropriate\npte_offset_kernel) and mm-wide page_table_lock, in sundry arch places.\n\nThe i386 vm86 mark_screen_rdonly: yes, there was and is an assumption that the\nscreen fits inside the one page table, as indeed it does.\n\nThe sh __do_page_fault: which handles both kernel faults (without lock) and\nuser mm faults (locked - though it set_pte without locking before).\n\nThe sh64 flush_cache_range and helpers: which wrongly thought callers held\npage_table_lock before (only its tlb_start_vma did, and no longer does so);\nmoved the flush loop down, and adjusted the large versus small range decision\nto consider a range which spans page tables as large.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nAcked-by: Paul Mundt \u003clethal@linux-sh.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c34d1b4d165c67b966bca4aba026443d7ff161eb", "tree": "27ffca9daba2a6b16d29bd508faf3e68bda2aad1", "parents": [ "c0718806cf955d5eb51ea77bffb5b21d9bba4972" ], "author": { "name": "Hugh Dickins", "email": "hugh@veritas.com", "time": "Sat Oct 29 18:16:32 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Oct 29 21:40:41 2005 -0700" }, "message": "[PATCH] mm: kill check_user_page_readable\n\ncheck_user_page_readable is a problematic variant of follow_page.
