The VDSO\ngettimeofday() algorithm computes the time in \"xsecs\", which are\nunits of 2^-20 seconds, or approximately 0.954 microseconds,\nusing the algorithm\n\n\tnow \u003d (timebase - tb_orig_stamp) * tb_to_xs + stamp_xsec\n\nand then converts the time in xsecs to seconds and microseconds.\n\nThe kernel updates the tb_orig_stamp and stamp_xsec values every\ntick in update_vsyscall(). If the length of the tick is not an\ninteger number of xsecs, then some precision is lost in converting\nthe current time to xsecs. For example, with CONFIG_HZ\u003d1000, the\ntick is 1ms long, which is 1048.576 xsecs. That means that\nstamp_xsec will advance by either 1048 or 1049 on each tick.\nWith the right conditions, it is possible for userspace to get\n(timebase - tb_orig_stamp) * tb_to_xs being 1049 if the kernel is\nslightly late in updating the vdso_datapage, and then for stamp_xsec\nto advance by 1048 when the kernel does update it, and for userspace\nto then see (timebase - tb_orig_stamp) * tb_to_xs being zero due to\ninteger truncation. The result is that time appears to go backwards\nby 1 microsecond.\n\nTo fix this we change the VDSO gettimeofday to use a new field in the\nVDSO datapage which stores the nanoseconds part of the time as a\nfractional number of seconds in a 0.32 binary fraction format.\n(Or put another way, as a 32-bit number in units of 0.23283 ns.)\nThis is convenient because we can use the mulhwu instruction to\nconvert it to either microseconds or nanoseconds.\n\nSince it turns out that computing the time of day using this new field\nis simpler than either using stamp_xsec (as gettimeofday does) or\nstamp_xtime.tv_nsec (as clock_gettime does), this converts both\ngettimeofday and clock_gettime to use the new field. The existing\n__do_get_tspec function is converted to use the new field and take\na parameter in r7 that indicates the desired resolution, 1,000,000\nfor microseconds or 1,000,000,000 for nanoseconds. The __do_get_xsec\nfunction is then unused and is deleted.\n\nThe new algorithm is\n\n\tnow \u003d ((timebase - tb_orig_stamp) \u003c\u003c 12) * tb_to_xs\n\t\t+ (stamp_xtime_seconds \u003c\u003c 32) + stamp_sec_fraction\n\nwith \u0027now\u0027 in units of 2^-32 seconds. That is then converted to\nseconds and either microseconds or nanoseconds with\n\n\tseconds \u003d now \u003e\u003e 32\n\tpartseconds \u003d ((now \u0026 0xffffffff) * resolution) \u003e\u003e 32\n\nThe 32-bit VDSO code also makes a further simplification: it ignores\nthe bottom 32 bits of the tb_to_xs value, which is a 0.64 format binary\nfraction. Doing so gets rid of 4 multiply instructions. Assuming\na timebase frequency of 1GHz or less and an update interval of no\nmore than 10ms, the upper 32 bits of tb_to_xs will be at least\n4503599, so the error from ignoring the low 32 bits will be at most\n2.2ns, which is more than an order of magnitude less than the time\ntaken to do gettimeofday or clock_gettime on our fastest processors,\nso there is no possibility of seeing inconsistent values due to this.\n\nThis also moves update_gtod() down next to its only caller, and makes\nupdate_vsyscall use the time passed in via the wall_time argument rather\nthan accessing xtime directly. At present, wall_time always points to\nxtime, but that could change in future.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "6b95ed345b9faa4ab3598a82991968f2e9f851bb", "tree": "71dea1106bbe0b4cd0a7f8ba18b9a3d47e80c9bf", "parents": [ "1a041a23da7c77b53c71fe11b4f940388bee37b1" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Fri Jul 09 10:21:21 2010 +0200" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Tue Jul 27 22:20:09 2010 +1000" }, "message": "perf, powerpc: Use perf_sample_data_init() for the FSL code\n\nWe should use perf_sample_data_init() to initialize struct\nperf_sample_data.

The VDSO\ngettimeofday() algorithm computes the time in \"xsecs\", which are\nunits of 2^-20 seconds, or approximately 0.954 microseconds,\nusing the algorithm\n\n\tnow \u003d (timebase - tb_orig_stamp) * tb_to_xs + stamp_xsec\n\nand then converts the time in xsecs to seconds and microseconds.\n\nThe kernel updates the tb_orig_stamp and stamp_xsec values every\ntick in update_vsyscall(). If the length of the tick is not an\ninteger number of xsecs, then some precision is lost in converting\nthe current time to xsecs. For example, with CONFIG_HZ\u003d1000, the\ntick is 1ms long, which is 1048.576 xsecs. That means that\nstamp_xsec will advance by either 1048 or 1049 on each tick.\nWith the right conditions, it is possible for userspace to get\n(timebase - tb_orig_stamp) * tb_to_xs being 1049 if the kernel is\nslightly late in updating the vdso_datapage, and then for stamp_xsec\nto advance by 1048 when the kernel does update it, and for userspace\nto then see (timebase - tb_orig_stamp) * tb_to_xs being zero due to\ninteger truncation. The result is that time appears to go backwards\nby 1 microsecond.\n\nTo fix this we change the VDSO gettimeofday to use a new field in the\nVDSO datapage which stores the nanoseconds part of the time as a\nfractional number of seconds in a 0.32 binary fraction format.\n(Or put another way, as a 32-bit number in units of 0.23283 ns.)\nThis is convenient because we can use the mulhwu instruction to\nconvert it to either microseconds or nanoseconds.\n\nSince it turns out that computing the time of day using this new field\nis simpler than either using stamp_xsec (as gettimeofday does) or\nstamp_xtime.tv_nsec (as clock_gettime does), this converts both\ngettimeofday and clock_gettime to use the new field. The existing\n__do_get_tspec function is converted to use the new field and take\na parameter in r7 that indicates the desired resolution, 1,000,000\nfor microseconds or 1,000,000,000 for nanoseconds. The __do_get_xsec\nfunction is then unused and is deleted.\n\nThe new algorithm is\n\n\tnow \u003d ((timebase - tb_orig_stamp) \u003c\u003c 12) * tb_to_xs\n\t\t+ (stamp_xtime_seconds \u003c\u003c 32) + stamp_sec_fraction\n\nwith \u0027now\u0027 in units of 2^-32 seconds. That is then converted to\nseconds and either microseconds or nanoseconds with\n\n\tseconds \u003d now \u003e\u003e 32\n\tpartseconds \u003d ((now \u0026 0xffffffff) * resolution) \u003e\u003e 32\n\nThe 32-bit VDSO code also makes a further simplification: it ignores\nthe bottom 32 bits of the tb_to_xs value, which is a 0.64 format binary\nfraction. Doing so gets rid of 4 multiply instructions. Assuming\na timebase frequency of 1GHz or less and an update interval of no\nmore than 10ms, the upper 32 bits of tb_to_xs will be at least\n4503599, so the error from ignoring the low 32 bits will be at most\n2.2ns, which is more than an order of magnitude less than the time\ntaken to do gettimeofday or clock_gettime on our fastest processors,\nso there is no possibility of seeing inconsistent values due to this.\n\nThis also moves update_gtod() down next to its only caller, and makes\nupdate_vsyscall use the time passed in via the wall_time argument rather\nthan accessing xtime directly. At present, wall_time always points to\nxtime, but that could change in future.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "5f07aa7524e98d6f68f2bec54f155ef6012e2c9a", "tree": "393b2db3213e6618ad1338f9b66019b0c05c6f75", "parents": [ "e467e104bb7482170b79f516d2025e7cfcaaa733", "d09ec7387184eba9e3030496f0451204090ff610" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Jul 09 11:25:48 2010 +1000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Jul 09 11:25:48 2010 +1000" }, "message": "Merge commit \u0027paulus-perf/master\u0027 into next\n" }, { "commit": "c2be05481f6125254c45b78f334d4dd09c701c82", "tree": "d5dc16f4d373bc88384b5716a9f72d0725e289ae", "parents": [ "3cd8519248e9e17d982c6fab0f1a89bca6feb49a" ], "author": { "name": "Paul E.
