the blktrace infrastructure\n\nThis drops the 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] 3046.491224: 8,1 A WBS 6367 + 8 \u003c- (8,1) 6304\n kjournald-305 [000] 3046.491227: 8,1 Q R 6367 + 8 [kjournald]\n

the preempt_count to show\nsoftirqs disabled, and before it called the lockdep code to\nhandle this, it causes a state that lockdep can not handle.\n\nThe preempt tracer will reset the ring buffer on

This patch moves the mmiotrace configuration options there.\nSince the Kconfig file, where the tracer menu is, is not architecture\nspecific, HAVE_MMIOTRACE_SUPPORT is introduced and provided only by\nx86/x86_64. CONFIG_MMIOTRACE now depends on it.\n\nSigned-off-by: Pekka Paalanen \u003cpq@iki.fi\u003e\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "034939b65ad5ff64b9709210b3469a95153c51a3", "tree": "14fc36bdcabc9c76ac179e4b39b7af11fcbdfb35", "parents": [ "67d347245f76a149c45bffb1a10145d31d61d1da" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Thu Jan 08 10:03:56 2009 -0800" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Jan 11 04:00:44 2009 +0100" }, "message": "tracing/ftrace: handle more than one stat file per tracer\n\nImpact: new API for tracers\n\nMake the stat tracing API reentrant.
