When the\ntracer allocate a return stack dynamically, the current depth is not\ninitialized before but after.

Since CR0.SO\nis used as the error indication from the system call, this means that\nall system calls appear to fail.\n\nThe reason is that the workaround for the timebase bug on Cell uses a\ncompare instruction. With CONFIG_VIRT_CPU_ACCOUNTING \u003d y, the\nACCOUNT_CPU_USER_ENTRY macro reads the timebase, so we end up doing a\ncompare instruction, which copies XER.SO to CR0.SO. Since we were\ndoing this in the system call entry patch after clearing CR0.SO but\nbefore saving the CR, this meant that the saved CR image had CR0.SO\nset if XER.SO was set on entry.\n\nThis fixes it by moving the clearing of CR0.SO to after the\nACCOUNT_CPU_USER_ENTRY call in the system call entry path.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "960cedb4e3eedec6394f224fc832c7a23f35a799", "tree": "09c0a325ac79ff81d4968ec6f4e22d88efbcfcb5", "parents": [ "cc353c30bbdb84f4317a6c149ebb11cde2232e40" ], "author": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Fri Nov 28 09:51:24 2008 +0000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Dec 01 09:40:18 2008 +1100" }, "message": "powerpc/cell: Fix GDB watchpoints, again\n\nAn earlier patch from Jens Osterkamp attempted to fix GDB\nwatchpoints by enabling the DABRX register at boot time.\nUnfortunately, this did not work on SMP setups, where\nsecondary CPUs were still using the power-on DABRX value.\n\nThis introduces the same change for secondary CPUs on cell\nas well.\n\nReported-by: Ulrich Weigand \u003cUlrich.Weigand@de.ibm.com\u003e\nTested-by: Ulrich Weigand \u003cUlrich.Weigand@de.ibm.com\u003e\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "cc353c30bbdb84f4317a6c149ebb11cde2232e40", "tree": "114558272ac12498546e3b19ba069a21e153a40f", "parents": [ "d015fe9951641b2d869a7ae4a690be2a05a9dc7f" ], "author": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Fri Nov 28 09:51:23 2008 +0000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Dec 01 09:40:18 2008 +1100" }, "message": "powerpc/mpic: Don\u0027t reset affinity for secondary MPIC on boot\n\nKexec/kdump currently fails on the IBM QS2x blades when the kexec happens\non a CPU other than the initial boot CPU.

readable output\n\nImpact: feature\n\nThis patch sets a C-like output for the function graph tracing.\nFor this aim, we now call two handler for each function: one on the entry\nand one other on return. This way we can draw a well-ordered call stack.\n\nThe pid of the previous trace is loosely stored to be compared against\nthe one of the current trace to see if there were a context switch.\n\nWithout this little feature, the call tree would seem broken at\nsome locations.\nWe could use the sched_tracer to capture these sched_events but this\nway of processing is much more simpler.\n\n2 spaces have been chosen for indentation to fit the screen while deep\ncalls. The time of execution in nanosecs is printed just after closed\nbraces, it seems more easy this way to find the corresponding function.\nIf the time was printed as a first column, it would be not so easy to\nfind the corresponding function if it is called on a deep depth.\n\nI plan to output the return value but on 32 bits CPU, the return value\ncan be 32 or 64, and its difficult to guess on which case we are.\nI don\u0027t know what would be the better solution on X86-32: only print\neax (low-part) or even edx (high-part).\n\nActually it\u0027s thee same problem when a function return a 8 bits value, the\nhigh part of eax could contain junk values...\n\nHere is an example of trace:\n\nsys_read() {\n fget_light() {\n } 526\n vfs_read() {\n rw_verify_area() {\n security_file_permission() {\n cap_file_permission() {\n } 519\n } 1564\n } 2640\n do_sync_read() {\n pipe_read() {\n __might_sleep() {\n } 511\n pipe_wait() {\n prepare_to_wait() {\n } 760\n deactivate_task() {\n dequeue_task() {\n dequeue_task_fair() {\n dequeue_entity() {\n update_curr() {\n update_min_vruntime() {\n } 504\n } 1587\n clear_buddies() {\n } 512\n add_cfs_task_weight() {\n } 519\n update_min_vruntime() {\n } 511\n } 5602\n dequeue_entity() {\n update_curr() {\n update_min_vruntime() {\n } 496\n } 1631\n clear_buddies() {\n } 496\n update_min_vruntime() {\n } 527\n } 4580\n hrtick_update() {\n hrtick_start_fair() {\n } 488\n } 1489\n } 13700\n } 14949\n } 16016\n msecs_to_jiffies() {\n } 496\n put_prev_task_fair() {\n } 504\n pick_next_task_fair() {\n } 489\n pick_next_task_rt() {\n } 496\n pick_next_task_fair() {\n } 489\n pick_next_task_idle() {\n } 489\n\n------------8\u003c---------- thread 4 ------------8\u003c----------\n\nfinish_task_switch() {\n} 1203\ndo_softirq() {\n __do_softirq() {\n __local_bh_disable() {\n } 669\n rcu_process_callbacks() {\n __rcu_process_callbacks() {\n cpu_quiet() {\n rcu_start_batch() {\n } 503\n } 1647\n } 3128\n __rcu_process_callbacks() {\n } 542\n } 5362\n _local_bh_enable() {\n } 587\n } 8880\n} 9986\nkthread_should_stop() {\n} 669\ndeactivate_task() {\n dequeue_task() {\n dequeue_task_fair() {\n dequeue_entity() {\n update_curr() {\n calc_delta_mine() {\n } 511\n update_min_vruntime() {\n } 511\n } 2813\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "fb52607afcd0629776f1dc9e657647ceae81dd50", "tree": "7bf43b41ff8510d3098c089913cce56a9049f0fd", "parents": [ "509dceef6470442d8c7b8a43ec34125205840b3c" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Tue Nov 25 21:07:04 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Nov 26 01:59:45 2008 +0100" }, "message": "tracing/function-return-tracer: change the name into function-graph-tracer\n\nImpact: cleanup\n\nThis patch changes the name of the \"return function tracer\" into\nfunction-graph-tracer which is a more suitable name for a tracing\nwhich makes one able to retrieve the ordered call stack during\nthe code flow.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "147dcf5489fb86c4bfe400520186f9f11b304783", "tree": "4ca9f7129caaae9d281b99a5dbc2156787af788b", "parents": [ "7953031da4200323ab5d85bd514054ca4ba9d225" ], "author": { "name": "Amit Kucheria", "email": "amit.kucheria@verdurent.com", "time": "Tue Nov 25 15:11:12 2008 -0800" }, "committer": { "name": "Tony Lindgren", "email": "tony@atomide.com", "time": "Tue Nov 25 15:11:12 2008 -0800" }, "message": "ARM: OMAP: Typo fix for clock_allow_idle\n\nThe second clk_deny_idle instance should be clk_allow_idle instead.\n\nSigned-off-by: Amit Kucheria \u003camit.kucheria@verdurent.com\u003e\nSigned-off-by: Tony Lindgren \u003ctony@atomide.com\u003e\n" }, { "commit": "a266d9f1253a38ec2d5655ebcd6846298b0554f4", "tree": "cc5dd897287dda9989c3b49990e3a888102d9cb1", "parents": [ "121fe86bdf062af3fed1e998c08c3c272ae6dc99" ], "author": { "name": "Andreas Herrmann", "email": "andreas.herrmann3@amd.com", "time": "Fri Nov 21 14:49:25 2008 +0100" }, "committer": { "name": "Dave Jones", "email": "davej@redhat.com", "time": "Tue Nov 25 13:38:29 2008 -0500" }, "message": "[CPUFREQ] powernow-k8: ignore out-of-range PstateStatus value\n\nA workaround for AMD CPU family 11h erratum 311 might cause that the\nP-state Status Register shows a \"current P-state\" which is larger than\nthe \"current P-state limit\" in P-state Current Limit Register.
