Furthermore this flush is\nhandled completely in hardware and should be 20-30 cycles.\n\nUnaligned loads on the other hand flush much more often - whenever\ncrossing a 128 byte cache line, or a 32 byte sector if either sector\nis an L1 miss.\n\nConsidering this information we really want to get the loads aligned\nand not worry about the alignment of the stores. Microbenchmarks\nconfirm that this approach is much faster than the current unaligned\ncopy loop that uses shifts and rotates to ensure both loads and\nstores are aligned.\n\nWe also want to try and do the stores in cacheline aligned, cacheline\nsized chunks. If the store queue is unable to merge an entire\ncacheline of stores then the L2 cache will have to do a\nread/modify/write. Even worse, we will serialise this with the stores\nin the next iteration of the copy loop since both iterations hit\nthe same cacheline.\n\nBased on this, the new loop does the following things:\n\n1 - 127 bytes\nGet the source 8 byte aligned and use 8 byte loads and stores. Pretty\nboring and similar to how the current loop works.\n\n128 - 4095 bytes\nGet the source 8 byte aligned and use 8 byte loads and stores,\n1 cacheline at a time. We aren\u0027t doing the stores in cacheline\naligned chunks so we will potentially serialise once per cacheline.\nEven so it is much better than the loop we have today.\n\n4096 - bytes\nIf both source and destination have the same alignment get them both\n16 byte aligned, then get the destination cacheline aligned. Do\ncacheline sized loads and stores using VMX.\n\nIf source and destination do not have the same alignment, we get the\ndestination cacheline aligned, and use permute to do aligned loads.\n\nIn both cases the VMX loop should be optimal - we always do aligned\nloads and stores and are always doing stores in cacheline aligned,\ncacheline sized chunks.\n\nTo be able to use VMX we must be careful about interrupts and\nsleeping. We don\u0027t use the VMX loop when in an interrupt (which should\nbe rare anyway) and we wrap the VMX loop in disable/enable_pagefault\nand fall back to the existing copy_tofrom_user loop if we do need to\nsleep.\n\nThe VMX breakpoint of 4096 bytes was chosen using this microbenchmark:\n\nhttp://ozlabs.org/~anton/junkcode/copy_to_user.c\n\nSince we are using VMX and there is a cost to saving and restoring\nthe user VMX state there are two broad cases we need to benchmark:\n\n- Best case - userspace never uses VMX\n\n- Worst case - userspace always uses VMX\n\nIn reality a userspace process will sit somewhere between these two\nextremes. Since we need to test both aligned and unaligned copies we\nend up with 4 combinations. The point at which the VMX loop begins to\nwin is:\n\n0% VMX\naligned\t\t2048 bytes\nunaligned\t2048 bytes\n\n100% VMX\naligned\t\t16384 bytes\nunaligned\t8192 bytes\n\nConsidering this is a microbenchmark, the data is hot in cache and\nthe VMX loop has better store queue merging properties we set the\nbreakpoint to 4096 bytes, a little below the unaligned breakpoints.\n\nSome future optimisations we can look at:\n\n- Looking at the perf data, a significant part of the cost when a\n task is always using VMX is the extra exception we take to restore\n the VMX state. As such we should do something similar to the x86\n optimisation that restores FPU state for heavy users. ie:\n\n /*\n * If the task has used fpu the last 5 timeslices, just do a full\n * restore of the math state immediately to avoid the trap; the\n * chances of needing FPU soon are obviously high now\n */\n preload_fpu \u003d tsk_used_math(next_p) \u0026\u0026 next_p-\u003efpu_counter \u003e 5;\n\n and\n\n /*\n * fpu_counter contains the number of consecutive context switches\n * that the FPU is used. If this is over a threshold, the lazy fpu\n * saving becomes unlazy to save the trap. This is an unsigned char\n * so that after 256 times the counter wraps and the behavior turns\n * lazy again; this to deal with bursty apps that only use FPU for\n * a short time\n */\n\n- We could create a paca bit to mirror the VMX enabled MSR bit and check\n that first, avoiding multiple calls to calling enable_kernel_altivec.\n That should help with iovec based system calls like readv.\n\n- We could have two VMX breakpoints, one for when we know the user VMX\n state is loaded into the registers and one when it isn\u0027t. This could\n be a second bit in the paca so we can calculate the break points quickly.\n\n- One suggestion from Ben was to save and restore the VSX registers\n we use inline instead of using enable_kernel_altivec.\n\n[BenH: Fixed a problem with preempt and fixed build without CONFIG_ALTIVEC]\n\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "0766387bcf162ecd875b4eb5f44e3ef057a3329b", "tree": "72a17c2c4221096001d42c4aa3e88a0e72d02425", "parents": [ "1e7342e7789fa2ca9202701467428726cbcfd649" ], "author": { "name": "Richard Kuo", "email": "rkuo@qualcomm.com", "time": "Tue Nov 29 08:28:20 2011 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Dec 16 14:39:48 2011 +1100" }, "message": "powerpc: Use rwsem.h from generic location\n\nAs of commit dd472da38, rwsem.h was moved into asm-generic.\nThis patch removes the arch file and points the build at\nits new location.\n\nSigned-off-by: Richard Kuo \u003crkuo@codeaurora.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "1e7342e7789fa2ca9202701467428726cbcfd649", "tree": "e0ad000924e9875bd2ea17bd0e04382491765a09", "parents": [ "78c5c68a4cf4329d17abfa469345ddf323d4fd62", "228d55053397e6d5325ca179c7ffe331de2846d3" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Dec 16 11:24:25 2011 +1100" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Dec 16 11:24:25 2011 +1100" }, "message": "Merge remote-tracking branch \u0027jwb/next\u0027 into next\n\nConflicts:\n\tarch/powerpc/platforms/40x/ppc40x_simple.c\n" }, { "commit": "78c5c68a4cf4329d17abfa469345ddf323d4fd62", "tree": "b83bf1b2fd8eea15e6c7d0cfc8d485445b7c6558", "parents": [ "8e609d5e7bc032ab220d47c841c992bd8544d0e1" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Dec 09 15:06:18 2011 +1100" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Dec 16 11:10:25 2011 +1100" }, "message": "powerpc/pmac: Fix SMP kernels on pre-core99 UP machines\n\nThe code for \"powersurge\" SMP would kick in and cause a crash\nat boot due to the lack of a NULL test.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "8e609d5e7bc032ab220d47c841c992bd8544d0e1", "tree": "24c90442699e1ed47605e58a019c43db52bde9fd", "parents": [ "a79dd5ae5a8f49688d65b89a859f2b98a7ee5538" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Mon Dec 12 10:27:41 2011 +1100" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Dec 16 11:10:11 2011 +1100" }, "message": "powerpc/pmac: Simplify old pmac PIC interrupt handling\n\nIn the old days, we treated all interrupts from the legacy Apple home made\ninterrupt controllers as level, with a trick reading the \"level\" register\nalong with the \"event\" register to work arounds bugs where it would\noccasionally fail to latch some events.\n\nDoing so appeared to work fine for both level and edge interrupts.\n\nLater on, we discovered in Darwin source the magic masks that define which\ninterrupts are actually level and which are edge, and implemented a\ndifferent algorithm, more similar to what Apple does, that treats those\ndifferently.\n\nI recently discovered however that this caused problems (including loss\nof interrupts) with an old Wallstreet PowerBook when trying to use the\ninternal modem (connected to a cascaded controller).\n\nIt looks like some interrupts are treated as edge while they are really\nlevel and I\u0027m starting to seriously doubt the correctness of the Darwin\ncode (which has other obvious bugs when you read it, so ...)\n\nThis patch reverts to our original behaviour of treating everything as\na level interrupt.
