Inspired from the Linux Kernel\nMarkers. Allows complete typing verification by declaring both tracing\nstatement inline functions and probe registration/unregistration static\ninline functions within the same macro \"DEFINE_TRACE\". No format string\nis required. See the tracepoint Documentation and Samples patches for\nusage examples.\n\nTaken from the documentation patch :\n\n\"A tracepoint placed in code provides a hook to call a function (probe)\nthat you can provide at runtime. A tracepoint can be \"on\" (a probe is\nconnected to it) or \"off\" (no probe is attached). When a tracepoint is\n\"off\" it has no effect, except for adding a tiny time penalty (checking\na condition for a branch) and space penalty (adding a few bytes for the\nfunction call at the end of the instrumented function and adds a data\nstructure in a separate section). When a tracepoint is \"on\", the\nfunction you provide is called each time the tracepoint is executed, in\nthe execution context of the caller. When the function provided ends its\nexecution, it returns to the caller (continuing from the tracepoint\nsite).\n\nYou can put tracepoints at important locations in the code. They are\nlightweight hooks that can pass an arbitrary number of parameters, which\nprototypes are described in a tracepoint declaration placed in a header\nfile.\"\n\nAddition and removal of tracepoints is synchronized by RCU using the\nscheduler (and preempt_disable) as guarantees to find a quiescent state\n(this is really RCU \"classic\"). The update side uses rcu_barrier_sched()\nwith call_rcu_sched() and the read/execute side uses\n\"preempt_disable()/preempt_enable()\".\n\nWe make sure the previous array containing probes, which has been\nscheduled for deletion by the rcu callback, is indeed freed before we\nproceed to the next update. It therefore limits the rate of modification\nof a single tracepoint to one update per RCU period. The objective here\nis to permit fast batch add/removal of probes on _different_\ntracepoints.\n\nChangelog :\n- Use #name \":\" #proto as string to identify the tracepoint in the\n tracepoint table. This will make sure not type mismatch happens due to\n connexion of a probe with the wrong type to a tracepoint declared with\n the same name in a different header.\n- Add tracepoint_entry_free_old.\n- Change __TO_TRACE to get rid of the \u0027i\u0027 iterator.\n\nMasami Hiramatsu \u003cmhiramat@redhat.com\u003e :\nTested on x86-64.\n\nPerformance impact of a tracepoint : same as markers, except that it\nadds about 70 bytes of instructions in an unlikely branch of each\ninstrumented function (the for loop, the stack setup and the function\ncall). It currently adds a memory read, a test and a conditional branch\nat the instrumentation site (in the hot path). Immediate values will\neventually change this into a load immediate, test and branch, which\nremoves the memory read which will make the i-cache impact smaller\n(changing the memory read for a load immediate removes 3-4 bytes per\nsite on x86_32 (depending on mov prefixes), or 7-8 bytes on x86_64, it\nalso saves the d-cache hit).\n\nAbout the performance impact of tracepoints (which is comparable to\nmarkers), even without immediate values optimizations, tests done by\nHideo Aoki on ia64 show no regression. His test case was using hackbench\non a kernel where scheduler instrumentation (about 5 events in code\nscheduler code) was added.\n\nQuoting Hideo Aoki about Markers :\n\nI evaluated overhead of kernel marker using linux-2.6-sched-fixes git\ntree, which includes several markers for LTTng, using an ia64 server.\n\nWhile the immediate trace mark feature isn\u0027t implemented on ia64, there\nis no major performance regression. So, I think that we don\u0027t have any\nissues to propose merging marker point patches into Linus\u0027s tree from\nthe viewpoint of performance impact.\n\nI prepared two kernels to evaluate. The first one was compiled without\nCONFIG_MARKERS. The second one was enabled CONFIG_MARKERS.\n\nI downloaded the original hackbench from the following URL:\nhttp://devresources.linux-foundation.org/craiger/hackbench/src/hackbench.c\n\nI ran hackbench 5 times in each condition and calculated the average and\ndifference between the kernels.\n\n The parameter of hackbench: every 50 from 50 to 800\n The number of CPUs of the server: 2, 4, and 8\n\nBelow is the results. As you can see, major performance regression\nwasn\u0027t found in any case. Even if number of processes increases,\ndifferences between marker-enabled kernel and marker- disabled kernel\ndoesn\u0027t increase. Moreover, if number of CPUs increases, the differences\ndoesn\u0027t increase either.\n\nCuriously, marker-enabled kernel is better than marker-disabled kernel\nin more than half cases, although I guess it comes from the difference\nof memory access pattern.\n\n* 2 CPUs\n\nNumber of | without | with | diff | diff |\nprocesses | Marker [Sec] | Marker [Sec] | [Sec] | [%]

support multiple probes\n\nRCU style multiple probes support for the Linux Kernel Markers. Common case\n(one probe) is still fast and does not require dynamic allocation or a\nsupplementary pointer dereference on the fast path.\n\n- Move preempt disable from the marker site to the callback.\n\nSince we now have an internal callback, move the preempt disable/enable to the\ncallback instead of the marker site.\n\nSince the callback change is done asynchronously (passing from a handler that\nsupports arguments to a handler that does not setup the arguments is no\narguments are passed), we can safely update it even if it is outside the\npreempt disable section.\n\n- Move probe arm to probe connection. Now, a connected probe is automatically\n armed.\n\nRemove MARK_MAX_FORMAT_LEN, unused.\n\nThis patch modifies the Linux Kernel Markers API : it removes the probe\n\"arm/disarm\" and changes the probe function prototype : it now expects a\nva_list * instead of a \"...\".\n\nIf we want to have more than one probe connected to a marker at a given\ntime (LTTng, or blktrace, ssytemtap) then we need this patch. Without it,\nconnecting a second probe handler to a marker will fail.\n\nIt allow us, for instance, to do interesting combinations :\n\nDo standard tracing with LTTng and, eventually, to compute statistics\nwith SystemTAP, or to have a special trigger on an event that would call\na systemtap script which would stop flight recorder tracing.\n\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@polymtl.ca\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Mike Mason \u003cmmlnx@us.ibm.com\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nCc: David Smith \u003cdsmith@redhat.com\u003e\nCc: \"Paul E.

The code is derived from arch/powerpc.\n\nThe advantages of having common BUG handling are:\n - consistent BUG reporting across architectures\n - shared implementation of out-of-line file/line data\n - implement CONFIG_DEBUG_BUGVERBOSE consistently\n\nThis means that in inline impact of BUG is just the illegal instruction\nitself, which is an improvement for i386 and x86-64.\n\nA BUG is represented in the instruction stream as an illegal instruction,\nwhich has file/line information associated with it. This extra information is\nstored in the __bug_table section in the ELF file.\n\nWhen the kernel gets an illegal instruction, it first confirms it might\npossibly be from a BUG (ie, in kernel mode, the right illegal instruction).\nIt then calls report_bug(). This searches __bug_table for a matching\ninstruction pointer, and if found, prints the corresponding file/line\ninformation. If report_bug() determines that it wasn\u0027t a BUG which caused the\ntrap, it returns BUG_TRAP_TYPE_NONE.\n\nSome architectures (powerpc) implement WARN using the same mechanism; if the\nillegal instruction was the result of a WARN, then report_bug(Q) returns\nCONFIG_DEBUG_BUGVERBOSE; otherwise it returns BUG_TRAP_TYPE_BUG.\n\nlib/bug.c keeps a list of loaded modules which can be searched for __bug_table\nentries. The architecture must call\nmodule_bug_finalize()/module_bug_cleanup() from its corresponding\nmodule_finalize/cleanup functions.\n\nUnsetting CONFIG_DEBUG_BUGVERBOSE will reduce the kernel size by some amount.\nAt the very least, filename and line information will not be recorded for each\nbut, but architectures may decide to store no extra information per BUG at\nall.\n\nUnfortunately, gcc doesn\u0027t have a general way to mark an asm() as noreturn, so\narchitectures will generally have to include an infinite loop (or similar) in\nthe BUG code, so that gcc knows execution won\u0027t continue beyond that point.\ngcc does have a __builtin_trap() operator which may be useful to achieve the\nsame effect, unfortunately it cannot be used to actually implement the BUG\nitself, because there\u0027s no way to get the instruction\u0027s address for use in\ngenerating the __bug_table entry.\n\n[randy.dunlap@oracle.com: Handle BUG\u003dn, GENERIC_BUG\u003dn to prevent build errors]\n[bunk@stusta.de: include/linux/bug.h must always #include \u003clinux/module.h]\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nCc: Andi Kleen \u003cak@muc.de\u003e\nCc: Hugh Dickens \u003chugh@veritas.com\u003e\nCc: Michael Ellerman \u003cmichael@ellerman.id.au\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f6a570333e554b48ad589e7137c77c57809eee81", "tree": "68dd6d5c8fe537a19a84a4189202f5cf70925c17", "parents": [ "2b5f6dcce5bf94b9b119e9ed8d537098ec61c3d2" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Oct 18 01:47:25 2006 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Dec 04 02:00:22 2006 -0500" }, "message": "[PATCH] severing module.h-\u003esched.h\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "e17e0f51aeea4e59c7e450a1c0f26605b91c1260", "tree": "eb177cbfe18d433ab115222bfe53f1098de844c2", "parents": [ "c957b32406b73ed66d0f20ebab0cab25c848105d" ], "author": { "name": "Kay Sievers", "email": "kay.sievers@vrfy.org", "time": "Fri Nov 24 12:15:25 2006 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri Dec 01 14:52:02 2006 -0800" }, "message": "Driver core: show drivers in /sys/module/\n\nShow the drivers, which belong to the module:\n $ ls -l /sys/module/usbcore/drivers/\n hub -\u003e ../../../bus/usb/drivers/hub\n usb -\u003e ../../../bus/usb/drivers/usb\n usbfs -\u003e ../../../bus/usb/drivers/usbfs\n\nSigned-off-by: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "fa3ba2e81ea23416272a22009bba95954c81969c", "tree": "cd1ab15dcf1130a4920ca9396cb91aaff4b0dcf6", "parents": [ "3719bc5c22c9025bf1c909fe8b527ebf1de9a153" ], "author": { "name": "Florin Malita", "email": "fmalita@gmail.com", "time": "Wed Oct 11 01:21:48 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 11 11:14:21 2006 -0700" }, "message": "[PATCH] fix Module taint flags listing in Oops/panic\n\nModule taint flags listing in Oops/panic has a couple of issues:\n\n* taint_flags() doesn\u0027t null-terminate the buffer after printing the flags\n\n* per-module taints are only set if the kernel is not already tainted\n (with that particular flag) \u003d\u003e only the first offending module gets its\n taint info correctly updated\n\nSome additional changes:\n\n* \u0027license_gplok\u0027 is no longer needed -

The autoinstaller feature, for\n example, which determines if your system has a \"good\" version of a\n driver (i.e. if the one provided by DKMS has a newer verson than that\n provided by the kernel package installed), and to automatically compile\n and install a newer version if DKMS has it but your kernel doesn\u0027t yet\n have that version.\n\nb) Because sysadmins manually, or with tools like DKMS, can switch out\n modules on the file system, you can\u0027t count on \u0027modinfo foo.ko\u0027, which\n looks at /lib/modules/${kernelver}/... actually matching what is loaded\n into the kernel already. Hence asking sysfs for this.\n\nc) as the unbind-driver-from-device work takes shape, it will be\n possible to rebind a driver that\u0027s built-in (no .ko to modinfo for the\n version) to a newly loaded module. sysfs will have the\n currently-built-in version info, for comparison.\n\nd) tech support scripts can then easily grab the version info for what\u0027s\n running presently - a question I get often.\n\nThere has been renewed interest in this patch on linux-scsi by driver\nauthors.\n\nAs the idea originated from GregKH, I leave his Signed-off-by: intact,\nthough the implementation is nearly completely new.
