This caused the output\nof the trace to look confusing when the parent seemed to be this\n\"kprobe_trampoline\" function.\n\nTo fix this, Abhishek Sagar added a test of the instruction pointer\nof the parent to see if it matched the kprobe_trampoline. If it\ndid, the output would print a \"[unknown/kretprobe\u0027d]\" instead.\n\nUnfortunately, not all archs do this the same way, and the trampoline\nfunction may not be exported, which causes failures in builds.\n\nThis patch will compare the name instead of the pointer to see\nif it matches. This prevents us from depending on a function from\nbeing exported, and should work on all archs. The worst that can\nhappen is that an arch might use a different name and then we\ngo back to the confusing output. At least the arch will still build.\n\nReported-by: Abhishek Sagar \u003csagar.abhishek@gmail.com\u003e\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nTested-by: Abhishek Sagar \u003csagar.abhishek@gmail.com\u003e\nAcked-by: Abhishek Sagar \u003csagar.abhishek@gmail.com\u003e\n" }, { "commit": "c2c80529460095035752bf0ecc1af82c1e0f6e0f", "tree": "e1fe0fdccb2d467666bfc8ed81f8a38016764f1c", "parents": [ "45beca08dd8b6d6a65c5ffd730af2eac7a2c7a03" ], "author": { "name": "Al Viro", "email": "viro@ZenIV.linux.org.uk", "time": "Fri Oct 31 19:50:41 2008 +0000" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Nov 03 10:12:13 2008 +0100" }, "message": "tracing, alpha: undefined reference to `save_stack_trace\u0027\n\nImpact: build fix on !stacktrace architectures\n\nonly select STACKTRACE on architectures that have STACKTRACE_SUPPORT\n\n... since we also need to ifdef out the guts of ftrace_trace_stack().\nWe also want to disallow setting TRACE_ITER_STACKTRACE in trace_flags\non such configs, but that can wait.\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nAcked-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "9244489a7b69fe0746dc7cb3957f02e05bd1ceb0", "tree": "f0fb4a422667f67e7e3ac587bbbc6b03fa83756a", "parents": [ "f3384b28a05624783b53836ccfed95ecde66a7ad" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Fri Oct 24 09:42:59 2008 -0400" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Oct 31 00:03:26 2008 +0100" }, "message": "ftrace: handle archs that do not support irqs_disabled_flags\n\nImpact: build fix on non-lockdep architectures\n\nSome architectures do not support a way to read the irq flags that\nis set from \"local_irq_save(flags)\" to determine if interrupts were\ndisabled or enabled.

The lock is\nnow only taken when a read needs to go to a new page.\n\nThis is far from lockless, and interrupts still need to be disabled,\nbut it is a step towards a more lockless solution, and it also\nsolves a lot of the issues that were noticed by the first conversion\nof ftrace to the ring buffers.\n\nNote: the ring_buffer_{un}lock API has been removed.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "9ff4b9744c187cae58c3774361ea090addbc4130", "tree": "f001a85312b374fbd91d332eb341d02522512da1", "parents": [ "2c4f035f6c3e8fda661eb6105aa51ef07aa71607" ], "author": { "name": "Pekka Paalanen", "email": "pq@iki.fi", "time": "Mon Sep 29 20:23:48 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 14 10:39:01 2008 +0200" }, "message": "tracing/ftrace: fix pipe breaking\n\nThis patch fixes a bug which break the pipe when the seq is empty.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "2c4f035f6c3e8fda661eb6105aa51ef07aa71607", "tree": "9bac9e431789f2f551b6b6b2f86463b0b568bf19", "parents": [ "777e208d40d0953efc6fb4ab58590da3f7d8f02d" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Mon Sep 29 20:18:34 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 14 10:39:00 2008 +0200" }, "message": "tracing/ftrace: change the type of the print_line callback\n\nWe need a kind of disambiguation when a print_line callback\nreturns 0.\n\n_There is not enough space to print all the entry.\n Please flush the seq and retry.\n_I can\u0027t handle this type of entry\n\nThis patch changes the type of this callback for better information.\n\nAlso some changes have been made in this V2.\n\n_ Only relay to default functions after the print_line callback fails.\n_ This patch doesn\u0027t fix the issue with the broken pipe (see patch 2/4 for that)\n\nSome things are still in discussion:\n\n_ Find better names for the enum print_line_t values\n_ Change the type of print_trace_line into boolean.\n\nPatches to change that can be sent later.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nAcked-by: Pekka Paalanen \u003cpq@iki.fi\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "777e208d40d0953efc6fb4ab58590da3f7d8f02d", "tree": "1e5940ccafd26c958b358f7ce85926659f12c37d", "parents": [ "3928a8a2d98081d1bc3c0a84a2d70e29b90ecf1c" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Mon Sep 29 23:02:42 2008 -0400" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 14 10:38:59 2008 +0200" }, "message": "ftrace: take advantage of variable length entries\n\nNow that the underlining ring buffer for ftrace now hold variable length\nentries, we can take advantage of this by only storing the size of the\nactual event into the buffer.

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" }, { "commit": "2e2ca155cd2213b4f398031180fb3d399d5b7db9", "tree": "027295832950e23ac4edc84e43550d02e9a1acc6", "parents": [ "fed1939c64d2288938fdc1c367d49082da65e195" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Fri Aug 01 12:26:40 2008 -0400" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 14 10:35:15 2008 +0200" }, "message": "ftrace: new continue entry - separate out from trace_entry\n\nSome tracers will need to work with more than one entry.

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, 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" }, { "commit": "d618b3e6e50970a6248ac857653fdd49bcd3c045", "tree": "1bf01a4c4092b9db9b3690a980b5260170ec6567", "parents": [ "9f6b4e3f4a24f2590f1c96f117fc45fbea9b0fa4" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon May 12 21:20:49 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri May 23 23:40:22 2008 +0200" }, "message": "ftrace: sysprof updates\n\nmake the sample period configurable.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "74f4e369fc5b52433ad824cef32d3bf1304549be", "tree": "c70d073a2740821f52d8b2b09f01626a06201e74", "parents": [ "5b82a1b08a00b2adca3d9dd9777efff40b7aaaa1" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon May 12 21:21:15 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri May 23 22:34:56 2008 +0200" }, "message": "ftrace: stacktrace fix\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "3eefae994d9224fb7771a3ddb683868363c23510", "tree": "0c7fe35765b485ff2a155c4ae1189199476a34b3", "parents": [ "6c6c27969a4c6024e6c8838829546c02aaddca18" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Mon May 12 21:21:04 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri May 23 22:05:14 2008 +0200" }, "message": "ftrace: limit trace entries\n\nCurrently there is no protection from the root user to use up all of\nmemory for trace buffers.

The new disable check makes\nthese calls into a nop.\n\nThis patch changes the __ftrace that is called without the check into a\nnew api for the other tracers to use, called \"trace_function\". The other\ntracers use this interface instead when the trace CPU buffer is already\ndisabled.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "2a2cc8f7c4d0dfd75720867f7dc58d24f075edfc", "tree": "58bccce0675debd5619757a45b5aba770bf32d0e", "parents": [ "aeaee8a2c9cb4489f166ca0e39c568e8254faaa6" ], "author": { "name": "Soeren Sandmann Pedersen", "email": "sandmann@redhat.com", "time": "Mon May 12 21:20:49 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri May 23 20:55:43 2008 +0200" }, "message": "ftrace: allow the event pipe to be polled\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "2577046740fe6d77864128c6187c11125c2449ea", "tree": "1d1c691dabce954915551cd06b2b138c287256dd", "parents": [ "5e3ca0ec76fce92daa4eed0d02de9c79b1fe3920" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon May 12 21:20:49 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri May 23 20:55:22 2008 +0200" }, "message": "ftrace: build fix\n\nno need to backmerge, only affects ftrace-enabled kernels.
