The algorithm for entering the kernel debug core and\nresuming kernel execution was racy and had several known edge case\nproblems with attempting to debug something on a heavily loaded system\nusing breakpoints that are hit repeatedly and quickly.\n\nThe prior \"locking\" design entry worked as follows:\n\n * The atomic counter kgdb_active was used with atomic exchange in\n order to elect a master cpu out of all the cpus that may have\n taken a debug exception.\n * The master cpu increments all elements of passive_cpu_wait[].\n * The master cpu issues the round up cpus message.\n * Each \"slave cpu\" that enters the debug core increments its own\n element in cpu_in_kgdb[].\n * Each \"slave cpu\" spins on passive_cpu_wait[] until it becomes 0.\n * The master cpu debugs the system.\n\nThe new scheme removes the two arrays of atomic counters and replaces\nthem with 2 single counters. One counter is used to count the number\nof cpus waiting to become a master cpu (because one or more hit an\nexception). The second counter is use to indicate how many cpus have\nentered as slave cpus.\n\nThe new entry logic works as follows:\n\n * One or more cpus enters via kgdb_handle_exception() and increments\n the masters_in_kgdb. Each cpu attempts to get the spin lock called\n dbg_master_lock.\n * The master cpu sets kgdb_active to the current cpu.\n * The master cpu takes the spinlock dbg_slave_lock.\n * The master cpu asks to round up all the other cpus.\n * Each slave cpu that is not already in kgdb_handle_exception()\n will enter and increment slaves_in_kgdb. Each slave will now spin\n try_locking on dbg_slave_lock.\n * The master cpu waits for the sum of masters_in_kgdb and slaves_in_kgdb\n to be equal to the sum of the online cpus.\n * The master cpu debugs the system.\n\nIn the new design the kgdb_active can only be changed while holding\ndbg_master_lock. Stress testing has not turned up any further\nentry/exit races that existed in the prior locking design. The prior\nlocking design suffered from atomic variables not being truly atomic\n(in the capacity as used by kgdb) along with memory barrier races.\n\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nAcked-by: Dongdong Deng \u003cdongdong.deng@windriver.com\u003e\n" }, { "commit": "c1bb9a9c1911036549c5cdfb23f32d7d20ffdc5a", "tree": "8d86976df36697e54ae3582d6c30b7355a942647", "parents": [ "91b152aa85bbcf076e269565394c31964f940371" ], "author": { "name": "Dongdong Deng", "email": "dongdong.deng@windriver.com", "time": "Mon Sep 13 06:58:00 2010 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Fri Oct 22 15:34:12 2010 -0500" }, "message": "debug_core: disable hw_breakpoints on all cores in kgdb_cpu_enter()\n\nThe slave cpus do not have the hw breakpoints disabled upon entry to\nthe debug_core and as a result could cause unrecoverable recursive\nfaults on badly placed breakpoints, or get out of sync with the arch\nspecific hw breakpoint operations.\n\nThis patch addresses the problem by invoking kgdb_disable_hw_debug()\nearlier in kgdb_enter_cpu for each cpu that enters the debug core.\n\nThe hw breakpoint dis/enable flow should be:\n\nmaster_debug_cpu slave_debug_cpu\n \\ /\n kgdb_cpu_enter\n |\n kgdb_disable_hw_debug --\u003e uninstall pre-enabled hw_breakpoint\n |\n do add/rm dis/enable operates to hw_breakpoints on master_debug_cpu..\n |\n correct_hw_break --\u003e correct/install the enabled hw_breakpoint\n |\n leave_kgdb\n\nSigned-off-by: Dongdong Deng \u003cdongdong.deng@windriver.com\u003e\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\n" }, { "commit": "91b152aa85bbcf076e269565394c31964f940371", "tree": "32b2a8684877a15b050ef21c8ddcd583b695538d", "parents": [ "75d14edee5689716b55afe467acfc13206a31f95" ], "author": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Mon Aug 23 09:20:14 2010 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Fri Oct 22 15:34:12 2010 -0500" }, "message": "kdb,kgdb: fix sparse fixups\n\nFix the following sparse warnings:\n\nkdb_main.c:328:5: warning: symbol \u0027kdbgetu64arg\u0027 was not declared.

"perf_events: Fix for transaction recovery in group_sched_in()\n\nThis new version (see commit 8e5fc1a) is much simpler and ensures that\nin case of error in group_sched_in() during event_sched_in(), the\nevents up to the failed event go through regular event_sched_out().\nBut the failed event and the remaining events in the group have their\ntimings adjusted as if they had also gone through event_sched_in() and\nevent_sched_out(). This ensures timing uniformity across all events in\na group. This also takes care of the tstamp_stopped problem in case\nthe group could never be scheduled. The tstamp_stopped is updated as\nif the event had actually run.\n\nWith this patch, the following now reports correct time_enabled,\nin case the NMI watchdog is active:\n\n$ task -e unhalted_core_cycles,instructions_retired,baclears,baclears\nnoploop 1\nnoploop for 1 seconds\n\n0 unhalted_core_cycles (100.00% scaling, ena\u003d997,552,872, run\u003d0)\n0 instructions_retired (100.00% scaling, ena\u003d997,552,872, run\u003d0)\n0 baclears (100.00% scaling, ena\u003d997,552,872, run\u003d0)\n0 baclears (100.00% scaling, ena\u003d997,552,872, run\u003d0)\n\nAnd the older test case also works:\n\n$ task -einstructions_retired,baclears,baclears -e\nunhalted_core_cycles,baclears,baclears sleep 5\n\n1680885 instructions_retired (69.39% scaling, ena\u003d950756, run\u003d291006)\n 10735 baclears (69.39% scaling, ena\u003d950756, run\u003d291006)\n 10735 baclears (69.39% scaling, ena\u003d950756, run\u003d291006)\n\n 0 unhalted_core_cycles (100.00% scaling, ena\u003d817932, run\u003d0)\n 0 baclears (100.00% scaling, ena\u003d817932, run\u003d0)\n 0 baclears (100.00% scaling, ena\u003d817932, run\u003d0)\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c4cbeeebc.8ee7d80a.5a28.0d5f@mx.google.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "9ffcfa6f1f63eeac15555b745c292eb9f59130f6", "tree": "803cc11f312da98713fdfc366b7ec79351dffa55", "parents": [ "96681fc3c9e7d1f89ab64e5eec40b6467c97680f" ], "author": { "name": "Stephane Eranian", "email": "eranian@google.com", "time": "Wed Oct 20 15:25:01 2010 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Oct 22 14:18:27 2010 +0200" }, "message": "perf_events: Revert: Fix transaction recovery in group_sched_in()\n\nThis patch reverts commit 8e5fc1a (perf_events: Fix transaction\nrecovery in group_sched_in()) because it had one flaw in case the\ngroup could never be scheduled.

This is due to\nevents only having a 27 bit field to store time.\n\nCurrently this time extend is a separate event. We add it just before\nthe event data that is being written to the buffer. But before\nthe event data is committed, the event data can also be discarded (as\nwith the case of filters). But because the time extend has already been\ncommitted, it will stay in the buffer.\n\nIf lots of events are being filtered and no event is being\nwritten, then every 134ms a time extend can be added to the buffer\nwithout any data attached. To keep from filling the entire buffer\nwith time extends, a time extend will never be the first event\nin a page because the page timestamp can be used. Time extends can\nonly fill the rest of a page with some data at the beginning.\n\nThis patch binds the time extend with the data. The difference here\nis that the time extend is not committed before the data is added.\nInstead, when a time extend is needed, the space reserved on\nthe ring buffer is the time extend + the data event size. The\ntime extend is added to the first part of the reserved block and\nthe data is added to the second. The time extend event is passed\nback to the reserver, but since the reserver also uses a function\nto find the data portion of the reserved block, no changes to the\nring buffer interface need to be made.\n\nWhen a commit is discarded, we now remove both the time extend and\nthe event. With this approach no more than one time extend can\nbe in the buffer in a row. Data must always follow a time extend.\n\nThanks to Mathieu Desnoyers for suggesting this idea.\n\nSuggested-by: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "f25106aeab7408394b9dd707e5ecf557e269c723", "tree": "58013e1e5eb776a921cbc8f3ef86267472fea8be", "parents": [ "e8bc43e84fada397af1b677b07dbf26e6ac78fcc" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Wed Oct 20 12:40:12 2010 -0400" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Wed Oct 20 12:40:12 2010 -0400" }, "message": "ring-buffer: Pass delta by value and not by reference\n\nThe delta between events is passed to the timestamp code by reference\nand the timestamp code will reset the value.
