This patch addresses this issue\nby adding a TRACE_FIELD_SPECIAL. The format is similar to TRACE_FIELD\nbut looks like so:\n\n TRACE_FIELD_SPECIAL(type_item, item, cmd)\n\nWhat TRACE_FIELD gave was:\n\n TRACE_FIELD(type, item, assign)\n\nThe TRACE_FIELD would be used in declaring a structure:\n\n struct {\n\ttype\titem;\n };\n\nAnd later assign it via:\n\n entry-\u003eitem \u003d assign;\n\nWhat TRACE_FIELD_SPECIAL gives us is:\n\nIn the declaration of the structure:\n\n struct {\n\ttype_item;\n };\n\nAnd the assignment:\n\n cmd;\n\nThis change log will explain the one example used in the patch:\n\n TRACE_EVENT_FORMAT(sched_switch,\n\tTPPROTO(struct rq *rq, struct task_struct *prev,\n\t\tstruct task_struct *next),\n\tTPARGS(rq, prev, next),\n\tTPFMT(\"task %s:%d \u003d\u003d\u003e %s:%d\",\n\t prev-\u003ecomm, prev-\u003epid, next-\u003ecomm, next-\u003epid),\n\tTRACE_STRUCT(\n\t\tTRACE_FIELD(pid_t, prev_pid, prev-\u003epid)\n\t\tTRACE_FIELD(int, prev_prio, prev-\u003eprio)\n\t\tTRACE_FIELD_SPECIAL(char next_comm[TASK_COMM_LEN],\n\t\t\t\t next_comm,\n\t\t\t\t TPCMD(memcpy(TRACE_ENTRY-\u003enext_comm,\n\t\t\t\t\t\t next-\u003ecomm,\n\t\t\t\t\t\t TASK_COMM_LEN)))\n\t\tTRACE_FIELD(pid_t, next_pid, next-\u003epid)\n\t\tTRACE_FIELD(int, next_prio, next-\u003eprio)\n\t),\n\tTPRAWFMT(\"prev %d:%d \u003d\u003d\u003e next %s:%d:%d\")\n\t);\n\n The struct will be create as:\n\n struct {\n\tpid_t\t\tprev_pid;\n\tint\t\tprev_prio;\n\tchar next_comm[TASK_COMM_LEN];\n\tpid_t\t\tnext_pid;\n\tint\t\tnext_prio;\n };\n\nNote the TRACE_ENTRY in the cmd part of TRACE_SPECIAL. 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": "340430c572f7b2b275d39965e88bafa71693cb23", "tree": "4be609589171a4bd8c5744178625454c6e5efa3a", "parents": [ "3e39aa156a24ce386da378784edd0f748c770087" ], "author": { "name": "Pekka Paalanen", "email": "pq@iki.fi", "time": "Tue Feb 24 21:44:15 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 02 10:20:37 2009 +0100" }, "message": "x86 mmiotrace: fix race with release_kmmio_fault_page()\n\nThere was a theoretical possibility to a race between arming a page in\npost_kmmio_handler() and disarming the page in\nrelease_kmmio_fault_page():\n\ncpu0 cpu1\n------------------------------------------------------------------\nmmiotrace shutdown\nenter release_kmmio_fault_page\n fault on the page\n disarm the page\ndisarm the page\n handle the MMIO access\n re-arm the page\nput the page on release list\nremove_kmmio_fault_pages()\n fault on the page\n page not known to mmiotrace\n fall back to do_page_fault()\n *KABOOM*\n\n(This scenario also shows the double disarm case which is allowed.)\n\nFixed by acquiring kmmio_lock in post_kmmio_handler() and checking\nif the page is being released from mmiotrace.\n\nSigned-off-by: Pekka Paalanen \u003cpq@iki.fi\u003e\nCc: Stuart Bennett \u003cstuart@freedesktop.org\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "3e39aa156a24ce386da378784edd0f748c770087", "tree": "2a36186a980cf7217ad6363887d4dabbbba4dcae", "parents": [ "0b700a6a253b6a3b3059bb9a9247a73490ee33fb" ], "author": { "name": "Stuart Bennett", "email": "stuart@freedesktop.org", "time": "Thu Feb 05 11:02:02 2009 +0000" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 02 10:20:37 2009 +0100" }, "message": "x86 mmiotrace: improve handling of secondary faults\n\nUpgrade some kmmio.c debug messages to warnings.\nAllow secondary faults on probed pages to fall through, and only log\nsecondary faults that are not due to non-present pages.\n\nPatch edited by Pekka Paalanen.\n\nSigned-off-by: Stuart Bennett \u003cstuart@freedesktop.org\u003e\nSigned-off-by: Pekka Paalanen \u003cpq@iki.fi\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "0b700a6a253b6a3b3059bb9a9247a73490ee33fb", "tree": "33841a4cb69fc3899cfa04113093440c91529f85", "parents": [ "5359b585fb5edb3db34d6cd491e1475b098c61d3" ], "author": { "name": "Pekka Paalanen", "email": "pq@iki.fi", "time": "Sun Mar 01 16:12:48 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 02 10:20:36 2009 +0100" }, "message": "x86 mmiotrace: split set_page_presence()\n\nFrom 36772dcb6ffbbb68254cbfc379a103acd2fbfefc Mon Sep 17 00:00:00 2001\nFrom: Pekka Paalanen \u003cpq@iki.fi\u003e\nDate: Sat, 28 Feb 2009 21:34:59 +0200\n\nSplit set_page_presence() in kmmio.c into two more functions set_pmd_presence()\nand set_pte_presence().
