      "message": "ftrace: preempt disable over interrupt disable\n\nWith the new ring buffer infrastructure in ftrace, I\u0027m trying to make\nftrace a little more light weight.\n\nThis patch converts a lot of the local_irq_save/restore into\npreempt_disable/enable.  The original preempt count in a lot of cases\nhas to be sent in as a parameter so that it can be recorded correctly.\nSome places were recording it incorrectly before anyway.\n\nThis is also laying the ground work to make ftrace a little bit\nmore reentrant, and remove all locking. The function tracers must\nstill protect from reentrancy.\n\nNote: All the function tracers must be careful when using preempt_disable.\n  It must do the following:\n\n  resched \u003d need_resched();\n  preempt_disable_notrace();\n  [...]\n  if (resched)\n\tpreempt_enable_no_resched_notrace();\n  else\n\tpreempt_enable_notrace();\n\nThe reason is that if this function traces schedule() itself, the\npreempt_enable_notrace() will cause a schedule, which will lead\nus into a recursive failure.\n\nIf we needed to reschedule before calling preempt_disable, we\nshould have already scheduled. Since we did not, this is most\nlikely that we should not and are probably inside a schedule\nfunction.\n\nIf resched was not set, we still need to catch the need resched\nflag being set when preemption was off and the if case at the\nend will catch that for us.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

That is a known danger of C typecasts,\nthere\u0027s absolutely zero checking done on them.\n\nHelp that problem a bit by using a GCC extension to implement a\ntype filter that restricts the types that a trace record can be\ncast into, and by adding a dynamic check (in debug mode) to verify\nthe type of the entry.\n\nThis patch adds a macro to assign all entries of ftrace using the type\nof the variable and checking the entry id. The typecasts are now done\nin the macro for only those types that it knows about, which should\nbe all the types that are allowed to be read from the tracer.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "ftrace: printk formatting infrastructure\n\nThis patch adds a feature that can help kernel developers debug their\ncode using ftrace.\n\n  int ftrace_printk(const char *fmt, ...);\n\nThis records into the ftrace buffer using printf formatting. The entry\nsize in the buffers are still a fixed length. A new type has been added\nthat allows for more entries to be used for a single recording.\n\nThe start of the print is still the same as the other entries.\n\nIt returns the number of characters written to the ftrace buffer.\n\nFor example:\n\nHaving a module with the following code:\n\nstatic int __init ftrace_print_test(void)\n{\n        ftrace_printk(\"jiffies are %ld\\n\", jiffies);\n        return 0;\n}\n\nGives me:\n\n  insmod-5441  3...1 7569us : ftrace_print_test: jiffies are 4296626666\n\nfor the latency_trace file and:\n\n          insmod-5441  [03]  1959.370498: ftrace_print_test jiffies are 4296626666\n\nfor the trace file.\n\nNote: Only the infrastructure should go into the kernel. It is to help\nfacilitate debugging for other kernel developers. Calls to ftrace_printk\nis not intended to be left in the kernel, and should be frowned upon just\nlike scattering printks around in the code.\n\nBut having this easily at your fingertips helps the debugging go faster\nand bugs be solved quicker.\n\nMaybe later on, we can hook this with markers and have their printf format\nbe sucked into ftrace output.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

I have my own\noutput formatting in place now.\n\nSummary of changes:\n- fix the NULL dereference that was due to not calling tracing_reset()\n- add print_line() callback into struct tracer\n- implement print_line() for mmiotrace, producing up-to-spec text\n- add my output header, but that is not really called in the right place\n- rewrote the main structs in mmiotrace\n- added two new trace entry types: TRACE_MMIO_RW and TRACE_MMIO_MAP\n- made some functions in trace.c non-static\n- check current\u003d\u003dNULL in tracing_generic_entry_update()\n- fix(?) comparison in trace_seq_printf()\n\nThings seem to work fine except a few issues. Markers (text lines injected\ninto mmiotrace log) are missing, I did not feel hacking them in before we\nhave variable length entries. My output header is printed only for \u0027trace\u0027\nfile, but not \u0027trace_pipe\u0027. For some reason, despite my quick fix,\niter-\u003etrace is NULL in print_trace_line() when called from \u0027trace_pipe\u0027\nfile, which means I don\u0027t get proper output formatting.\n\nI only tried by loading nouveau.ko, which just detects the card, and that\nis traced fine. I didn\u0027t try further. Map, two reads and unmap. Works\nperfectly.\n\nI am missing the information about overflows, I\u0027d prefer to have a\ncounter for lost events. I didn\u0027t try, but I guess currently there is no\nway of knowning when it overflows?\n\nSo, not too far from being fully operational, it seems :-)\nAnd looking at the diffstat, there also is some 700-900 lines of user space\ncode that just became obsolete.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n"

This file is a consumer of the trace buffers.\nThis means that reads of this file consumes the entries from\nthe trace buffers so that they will not be read a second time,\nas contrast to the static buffers latency_trace and trace.\n\nReading from the trace_pipe will remove the entries from trace\nand latency_trace too.\n\nThe advantage that trace_pipe has is that it can record live\ntraces. It will block when there is nothing in the buffer,\nand read the entries as they are entered.
