The dynamic function trace\nallows you to pick and choose which of those functions will be\ntraced, but all functions being traced will call all tracers that\nregistered with the function tracer.\n\nThis patch adds a new feature that allows a tracer to hook to specific\nfunctions, even when all functions are being traced. It allows for\ndifferent functions to call different tracer hooks.\n\nThe way this is accomplished is by a special function that will hook\nto the function tracer and will set up a hash table knowing which\ntracer hook to call with which function. This is the most general\nand easiest method to accomplish this. Later, an arch may choose\nto supply their own method in changing the mcount call of a function\nto call a different tracer. But that will be an exercise for the\nfuture.\n\nTo register a function:\n\n struct ftrace_hook_ops {\n\tvoid\t\t\t(*func)(unsigned long ip,\n\t\t\t\t\tunsigned long parent_ip,\n\t\t\t\t\tvoid **data);\n\tint\t\t\t(*callback)(unsigned long ip, void **data);\n\tvoid\t\t\t(*free)(void **data);\n };\n\n int register_ftrace_function_hook(char *glob, struct ftrace_hook_ops *ops,\n\t\t\t\t void *data);\n\nglob is a simple glob to search for the functions to hook.\nops is a pointer to the operations (listed below)\ndata is the default data to be passed to the hook functions when traced\n\nops:\n func is the hook function to call when the functions are traced\n callback is a callback function that is called when setting up the hash.\n That is, if the tracer needs to do something special for each\n function, that is being traced, and wants to give each function\n its own data. The address of the entry data is passed to this\n callback, so that the callback may wish to update the entry to\n whatever it would like.\n free is a callback for when the entry is freed. In case the tracer\n allocated any data, it is give the chance to free it.\n\nTo unregister we have three functions:\n\n void\n unregister_ftrace_function_hook(char *glob, struct ftrace_hook_ops *ops,\n\t\t\t\tvoid *data)\n\nThis will unregister all hooks that match glob, point to ops, and\nhave its data matching data.

}, "message": "ring-buffer: add NMI protection for spinlocks\n\nImpact: prevent deadlock in NMI\n\nThe ring buffers are not yet totally lockless with writing to\nthe buffer. When a writer crosses a page, it grabs a per cpu spinlock\nto protect against a reader. The spinlocks taken by a writer are not\nto protect against other writers, since a writer can only write to\nits own per cpu buffer. The spinlocks protect against readers that\ncan touch any cpu buffer. The writers are made to be reentrant\nwith the spinlocks disabling interrupts.\n\nThe problem arises when an NMI writes to the buffer, and that write\ncrosses a page boundary. If it grabs a spinlock, it can be racing\nwith another writer (since disabling interrupts does not protect\nagainst NMIs) or with a reader on the same CPU. Luckily, most of the\nusers are not reentrant and protects against this issue. But if a\nuser of the ring buffer becomes reentrant (which is what the ring\nbuffers do allow), if the NMI also writes to the ring buffer then\nwe risk the chance of a deadlock.\n\nThis patch moves the ftrace_nmi_enter called by nmi_enter() to the\nring buffer code. It replaces the current ftrace_nmi_enter that is\nused by arch specific code to arch_ftrace_nmi_enter and updates\nthe Kconfig to handle it.\n\nWhen an NMI is called, it will set a per cpu variable in the ring buffer\ncode and will clear it when the NMI exits. If a write to the ring buffer\ncrosses page boundaries inside an NMI, a trylock is used on the spin\nlock instead. If the spinlock fails to be acquired, then the entry\nis discarded.\n\nThis bug appeared in the ftrace work in the RT tree, where event tracing\nis reentrant. This workaround solved the deadlocks that appeared there.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n" }, { "commit": "1830b52d0de8c60c4f5dfbac134aa8f69d815801", "tree": "2aa803853ac145fedd0d65324d77f64d25e7b3a2", "parents": [ "43769f10b4826376cbf4ce17af74a5b4e8dc4fcd" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Sat Feb 07 19:38:43 2009 -0500" }, "committer": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Sat Feb 07 19:38:43 2009 -0500" }, "message": "trace: remove deprecated entry-\u003ecpu\n\nImpact: fix to prevent developers from using entry-\u003ecpu\n\nWith the new ring buffer infrastructure, the cpu for the entry is\nimplicit with which CPU buffer it is on.\n\nThe original code use to record the current cpu into the generic\nentry header, which can be retrieved by entry-\u003ecpu.

requirement of userspace utilities to use the blktrace\nfacility.\n\nConfiguration is done thru sysfs, adding a \"trace\" directory to the\npartition directory where blktrace can be enabled for the associated\nrequest_queue.\n\nThe same filters present in the IOCTL interface are present as sysfs\ndevice attributes.\n\nThe /sys/block/sdX/sdXN/trace/enable file allows tracing without any\nfilters.\n\nThe other files in this directory: pid, act_mask, start_lba and end_lba\ncan be used with the same meaning as with the IOCTL interface.\n\nUsing the sysfs interface will only setup the request_queue-\u003eblk_trace\nfields, tracing will only take place when the \"blk\" tracer is selected\nvia the ftrace interface, as in the following example:\n\nTo see the trace, one can use the /d/tracing/trace file or the\n/d/tracign/trace_pipe file, with semantics defined in the ftrace\ndocumentation in Documentation/ftrace.txt.\n\n[root@f10-1 ~]# cat /t/trace\n kjournald-305 [000]
