2012-10-17perf hists browser: Add back callchain folding symbolArnaldo Carvalho de Melo1-1/+1
The commit 5395a04841fc ("perf hists: Separate overhead and baseline columns") makes the "Overhead" column no more the first one, this caused the test that checks if it is time to show if a histogram entry has callchains never hits. Fix it by checking if the 'i' variable is equal to PERF_HPP__OVERHEAD instead of 0.

2012-10-17perf python: Initialize 'page_size' variableArnaldo Carvalho de Melo1-0/+2
The commit 0c1fe6b: 'perf tools: Have the page size value available for all tools' Broke the python binding because the global variable 'page_size' is initialized on the main() routine, that is not called when using just the python binding, causing evlist.mmap() to fail because it expects that variable to be initialized to the system's page size. Fix it by initializing it on the binding init routine.

2012-10-16lib tools traceevent: Add back pevent assignment in __pevent_parse_format()Steven Rostedt1-3/+6
Even though with the change of commit commit 2b29175 "tools lib traceevent: Carve out events format parsing routine", allowed __pevent_parse_format() to parse an event without the need of a pevent handler, the event still needs to assign the pevent handed to it. There's no problem with assigning it if the pevent is NULL, as the event->pevent would be NULL without the assignment. But function parsing handlers may be assigned to the pevent handler to help in parsing the event. If there's no pevent then there would not be any function handlers, but if the pevent isn't assigned first before parsing the event, it wont honor the function handlers that were assigned. Worse yet, the current code crashes if an event has a function that it tries to parse. For example: # perf record -e scsi:scsi_dispatch_cmd_timeout Segmentation fault (core dumped) This happens because the scsi_dispatch_cmd_timeout event format has the following: scsi_trace_parse_cdb(p, __get_dynamic_array(cmnd), REC->cmd_len) which hasn't been defined by the pevent code.

2012-10-16perf tool: Precise mode requires exclude_guestDavid Ahern1-0/+3
Summary of events per Peter: "Intel PEBS in VT-x context uses the DS address as a guest linear address, even though its programmed by the host as a host linear address. This either results in guest memory corruption and or the hardware faulting and 'crashing' the virtual machine. Therefore we have to disable PEBS on VT-x enter and re-enable on VT-x exit, enforcing a strict exclude_guest. AMB IBS does work but doesn't currently support exclude_* at all, setting an exclude_* bit will make it fail." This patch handles userspace perf command, setting the exclude_guest attribute if precise mode is requested, but only if a user has not specified a request for guest or host only profiling (G or H attribute). Kernel side AMD currently ignores all exclude_* bits, so there is no impact to existing IBS code paths. Robert Richter has a patch where IBS code will return EINVAL if an exclude_* bit is set. When this goes in it means use of :p on AMD with IBS will first fail with EINVAL (because exclude_guest will be set). Then the existing fallback code within perf will unset exclude_guest and try again. The second attempt will succeed if the CPU supports IBS profiling.

2012-10-04perf hists: Separate overhead and baseline columnsJiri Olsa3-28/+58
Currently the overhead and baseline columns are handled within single function and the distinction is made by 'baseline hists' pointer passed by 'struct perf_hpp::ptr'. Since hists pointer is now part of each hist_entry, it's possible to locate paired hists pointer directly from the passed struct hist_entry pointer. Also separating those 2 columns makes the code more obvious.

2012-10-03perf inject: Remove static variablesArnaldo Carvalho de Melo1-34/+38
We want to reduce the impact that each of the builtins has on perf as a whole, so use the superclassing of perf_tool mechanizm to move its config knobs to the stack, so that only if we use that tool, its impact will be felt. In this case is more about consistency, as the impact of this tool is minimal.

If we ever want to allow inject to work with something other than stdin, we can put it back, but so far it is completely unused, so ditch it.

I.e. we don't need to resolve the evsel via the id and then check if it is this or that event, just stash the right handler at evsel creation time, then use evsel->handler.func() straight away.

2012-10-03perf tools: Convert to GTK2_SUPPORTNamhyung Kim6-36/+36
For building perf without gtk+2, we can set NO_GTK2=1 as a argument of make. It then defines NO_GTK2_SUPPORT macro for C code to do the proper handling. However it usually used in a negative semantics - e.g. #ifndef - so we saw double negations which can be misleading. Convert it to a positive form to make it more readable.
