The only updated macro in this patch is the\nsched_switch trace point.\n\nThe old method looked like this:\n\n TRACE_EVENT_FORMAT(sched_switch,\n TP_PROTO(struct rq *rq, struct task_struct *prev,\n struct task_struct *next),\n TP_ARGS(rq, prev, next),\n TP_FMT(\"task %s:%d \u003d\u003d\u003e %s:%d\",\n prev-\u003ecomm, prev-\u003epid, next-\u003ecomm, next-\u003epid),\n TRACE_STRUCT(\n TRACE_FIELD(pid_t, prev_pid, prev-\u003epid)\n TRACE_FIELD(int, prev_prio, prev-\u003eprio)\n TRACE_FIELD_SPECIAL(char next_comm[TASK_COMM_LEN],\n next_comm,\n TP_CMD(memcpy(TRACE_ENTRY-\u003enext_comm,\n next-\u003ecomm,\n TASK_COMM_LEN)))\n TRACE_FIELD(pid_t, next_pid, next-\u003epid)\n TRACE_FIELD(int, next_prio, next-\u003eprio)\n ),\n TP_RAW_FMT(\"prev %d:%d \u003d\u003d\u003e next %s:%d:%d\")\n );\n\nThe above method is hard to read and requires two format fields.\n\nThe new method:\n\n /*\n * Tracepoint for task switches, performed by the scheduler:\n *\n * (NOTE: the \u0027rq\u0027 argument is not used by generic trace events,\n * but used by the latency tracer plugin. )\n */\n TRACE_EVENT(sched_switch,\n\n\tTP_PROTO(struct rq *rq, struct task_struct *prev,\n\t\t struct task_struct *next),\n\n\tTP_ARGS(rq, prev, next),\n\n\tTP_STRUCT__entry(\n\t\t__array(\tchar,\tprev_comm,\tTASK_COMM_LEN\t)\n\t\t__field(\tpid_t,\tprev_pid\t\t\t)\n\t\t__field(\tint,\tprev_prio\t\t\t)\n\t\t__array(\tchar,\tnext_comm,\tTASK_COMM_LEN\t)\n\t\t__field(\tpid_t,\tnext_pid\t\t\t)\n\t\t__field(\tint,\tnext_prio\t\t\t)\n\t),\n\n\tTP_printk(\"task %s:%d [%d] \u003d\u003d\u003e %s:%d [%d]\",\n\t\t__entry-\u003eprev_comm, __entry-\u003eprev_pid, __entry-\u003eprev_prio,\n\t\t__entry-\u003enext_comm, __entry-\u003enext_pid, __entry-\u003enext_prio),\n\n\tTP_fast_assign(\n\t\tmemcpy(__entry-\u003enext_comm, next-\u003ecomm, TASK_COMM_LEN);\n\t\t__entry-\u003eprev_pid\t\u003d prev-\u003epid;\n\t\t__entry-\u003eprev_prio\t\u003d prev-\u003eprio;\n\t\tmemcpy(__entry-\u003eprev_comm, prev-\u003ecomm, TASK_COMM_LEN);\n\t\t__entry-\u003enext_pid\t\u003d next-\u003epid;\n\t\t__entry-\u003enext_prio\t\u003d next-\u003eprio;\n\t)\n );\n\nThis macro is called TRACE_EVENT, it is broken up into 5 parts:\n\n TP_PROTO: the proto type of the trace point\n TP_ARGS: the arguments of the trace point\n TP_STRUCT_entry: the structure layout of the entry in the ring buffer\n TP_printk: the printk format\n TP_fast_assign: the method used to write the entry into the ring buffer\n\nThe structure is the definition of how the event will be saved in the\nring buffer. The printk is used by the internal tracing in case of\nan oops, and the kernel needs to print out the format of the record\nto the console. This the TP_printk gives a means to show the records\nin a human readable format. It is also used to print out the data\nfrom the trace file.\n\nThe TP_fast_assign is executed directly. It is basically like a C function,\nwhere the __entry is the handle to the record.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n" }, { "commit": "2939b0469d04ba9ac791aca9a81625d7eb50662b", "tree": "573f10c39f34c670fdc6832415642738c5afb3f9", "parents": [ "156b5f172a64103bcb13b6d26288388b9019caa3" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Mon Mar 09 15:47:18 2009 -0400" }, "committer": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Tue Mar 10 00:35:04 2009 -0400" }, "message": "tracing: replace TP\u003cvar\u003e with TP_\u003cvar\u003e\n\nImpact: clean up\n\nThe macros TPPROTO, TPARGS, TPFMT, TPRAWFMT, and TPCMD all look a bit\nugly.

Then the developer can examine the trace, and restart\ntracing if they want to try again (echo 1 \u003e tracing_on).\n\nThis patch moves the prototypes for tracing_on/tracing_off to kernel.h\nand comments their use, so that a kernel developer will know how\nto use them.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n" }, { "commit": "ebcad5aaea26da3cb2ca90b7f31a67a027eb60db", "tree": "cff7c96fa8573c241074689cf8c399e71bc97fb5", "parents": [ "e565f206082a725108a75bcf00bbe3db21a56474" ], "author": { "name": "Bartlomiej Zolnierkiewicz", "email": "bzolnier@gmail.com", "time": "Thu Mar 05 16:10:59 2009 +0100" }, "committer": { "name": "Bartlomiej Zolnierkiewicz", "email": "bzolnier@gmail.com", "time": "Thu Mar 05 16:10:59 2009 +0100" }, "message": "remove stale comment from \u003clinux/hdreg.h\u003e\n\nHDIO_GET_IDENTITY returns 256 words currently.\n\nNoticed by Norman Diamond.\n\nSigned-off-by: Bartlomiej Zolnierkiewicz \u003cbzolnier@gmail.com\u003e\n" }, { "commit": "849d7130001ab740a5a4778a561049841fdd77c9", "tree": "c7031ed3d3aa24270d0f001d3616698aeb3fe39a", "parents": [ "a509538d4fb4f99cdf0a095213d57cc3b2347615" ], "author": { "name": "Stanislaw Gruszka", "email": "stf_xl@wp.pl", "time": "Thu Mar 05 16:10:57 2009 +0100" }, "committer": { "name": "Bartlomiej Zolnierkiewicz", "email": "bzolnier@gmail.com", "time": "Thu Mar 05 16:10:57 2009 +0100" }, "message": "ide: allow to wrap interrupt handler\n\nSigned-off-by: Stanislaw Gruszka \u003cstf_xl@wp.pl\u003e\nCc: Andrew Victor \u003clinux@maxim.org.za\u003e\n[bart: minor checkpatch.pl / CodingStyle fixups]\nSigned-off-by: Bartlomiej Zolnierkiewicz \u003cbzolnier@gmail.com\u003e\n" }, { "commit": "84bda12af31f930e4200c5244aa111de2485d7b0", "tree": "08d214bf7a1ce56e8c994e7970513bfb4b215e3d", "parents": [ "5825627c9463581fd9e70f8285685889ae5bb9bb" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Mon Mar 02 18:53:26 2009 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Thu Mar 05 07:25:02 2009 -0500" }, "message": "libata: align ap-\u003esector_buf\n\nap-\u003esector_buf is used as DMA target and should at least be aligned on\ncacheline.

TRACE_ENTRY will\nbe set by the tracer to point to the structure inside the trace buffer.\n\n entry-\u003eprev_pid\t\u003d prev-\u003epid;\n entry-\u003eprev_prio\t\u003d prev-\u003eprio;\n memcpy(entry-\u003enext_comm, next-\u003ecomm, TASK_COMM_LEN);\n entry-\u003enext_pid\t\u003d next-\u003epid;\n entry-\u003enext_prio\t\u003d next-\u003eprio\n\nReported-by: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n" }, { "commit": "f180053694b43d5714bf56cb95499a3c32ff155c", "tree": "00286fcc88d2842629b039da4009a1332b3a1719", "parents": [ "34754b69a6f87aa6aa2860525a82f12532f83afd" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 02 11:00:57 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 02 11:06:49 2009 +0100" }, "message": "x86, mm: dont use non-temporal stores in pagecache accesses\n\nImpact: standardize IO on cached ops\n\nOn modern CPUs it is almost always a bad idea to use non-temporal stores,\nas the regression in this commit has shown it:\n\n 30d697f: x86: fix performance regression in write() syscall\n\nThe kernel simply has no good information about whether using non-temporal\nstores is a good idea or not - and trying to add heuristics only increases\ncomplexity and inserts fragility.\n\nThe regression on cached write()s took very long to be found - over two\nyears.

Add\nin a check to see if a user can attach an rt task to its task group.\nOn failure, return EINVAL, which is also returned in\nCONFIG_CGROUP_SCHED.\n\nReported-by: Corey Hickey \u003cbugfood-ml@fatooh.org\u003e\nSigned-off-by: Dhaval Giani \u003cdhaval@linux.vnet.ibm.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "f701d354075914296474d062f18fc8ee681a2318", "tree": "4c39db49f4bc9827a1a0dabc6a83fb30bd2c7ac4", "parents": [ "1b49061d400c9e51e3ac2aac026a099fe599b9bb", "64e71303e44f3697e4568147caa966de74bdb4fb" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 27 09:04:43 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 27 09:04:43 2009 +0100" }, "message": "Merge branches \u0027tracing/ftrace\u0027 and \u0027linus\u0027 into tracing/core\n" }, { "commit": "1b49061d400c9e51e3ac2aac026a099fe599b9bb", "tree": "54c632cd7f0be2573897c1463a247e69fb769940", "parents": [ "14131f2f98ac350ee9e73faed916d2238a8b6a0d", "83ce400928680a6c8123d492684b27857f5a2d95" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 26 21:21:59 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 27 08:35:19 2009 +0100" }, "message": "Merge branch \u0027sched/clock\u0027 into tracing/ftrace\n\nConflicts:\n\tkernel/sched_clock.c\n" }, { "commit": "5d0859cef29167d45dc6cf89d19712145e6005d6", "tree": "1fe3be14cc773f4df5606a9993930cc43889a169", "parents": [ "14131f2f98ac350ee9e73faed916d2238a8b6a0d", "83ce400928680a6c8123d492684b27857f5a2d95" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 26 21:21:59 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 26 21:21:59 2009 +0100" }, "message": "Merge branch \u0027sched/clock\u0027 into tracing/ftrace\n\nConflicts:\n\tkernel/sched_clock.c\n" }, { "commit": "b342501cd31e5546d0c9ca8ceff5ded1832f9e5b", "tree": "3cd5778565a45a74e8ad0640093927a77d4d625e", "parents": [ "694593e3374a67d95ece6a275a1f181644c2c4d8" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 26 20:20:29 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 26 21:20:22 2009 +0100" }, "message": "sched: allow architectures to specify sched_clock_stable\n\nAllow CONFIG_HAVE_UNSTABLE_SCHED_CLOCK architectures to still specify\nthat their sched_clock() implementation is reliable.\n\nThis will be used by x86 to switch on a faster sched_clock_cpu()\nimplementation on certain CPU types.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "14131f2f98ac350ee9e73faed916d2238a8b6a0d", "tree": "bf490d104276142e914f1245bbc9f44cb0d2bc9b", "parents": [ "6409c4da289d6905f7ae2bd0630438368439bda2" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 26 18:47:11 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 26 18:44:06 2009 +0100" }, "message": "tracing: implement trace_clock_*() APIs\n\nImpact: implement new tracing timestamp APIs\n\nAdd three trace clock variants, with differing scalability/precision\ntradeoffs:\n\n -
