* perf tools: Makefile: Use gcc to determine ARCHLin Ming2011-05-071-6/+10
| | | | | | | | | | | | | | | | | | | The original Makefile uses "uname -m" to determine ARCH. This causes problem on x86 when compile perf tool on 32 bit userspace with a 64 bit kernel. bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages: bench/../../../arch/x86/lib/memcpy_64.S:28: Error: bad register name `%rdi' This is because "uname -m" returns x86_64 and memcpy_64.S is included in 32 bit build.

* perf evsel: Fix use of inheritArnaldo Carvalho de Melo2011-04-158-42/+41
| | | | | | | | | | | | | | | | | | | | | | | perf stat doesn't mmap and its perfectly fine for it to use task-bound counters with inheritance. So set the attr.inherit on the caller and leave the syscall itself to validate it. When the mmap fails perf_evlist__mmap will just emit a warning if this is the failure reason.

* perf hists browser: Fix seg fault when annotate null symbolLin Ming2011-04-152-3/+5
| | | | | | | | | | | | | | | | | | In hists browser, press hotkey 'a' to annotate current symbol. Now it causes segment fault if 'a' is pressed on a null symbol. Here are 2 small bugs: - In perf_evsel__hists_browse, the condition check after 'a' is pressed is not correct, we should check ->sym instead of ->map. - In symbol__tui_annotate we must check whether sym is NULL or not before getting annotation structure. This patch fixes above 2 small bugs.

This patch updates find_perf_probe_point() and introduces new rules to get correct line number. - If debuginfo doesn't have a correct file name, we shouldn't return line number too, because, without file name, line number is meaningless. - If the address is in a function, it stores the function name and the offset from the function entry. - If the address is on a line, it tries to get the relative line number from the function entry line, except for the address is same as the entry address of the function (in this case, the relative line number should be 0). - If the address is in an inline function entry (call-site), it uses the inline function call line number as the line on which the address is. - If the address is in an inline function body, it stores the inline function name and offset from the inline function call site instead of the (non-inlined) function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default setting of perf record is to mmap 128 pages if the user did not override with -m. However the page size may vary accross different architecture settings, giving different default size between each. Moreover the kernel side still has a default max number of mlocked pages of 512 kiB + 1 page for unprivileged users. 128 + 1 pages with page size > 4096 overlaps this threshold. Thus, better adapt to this limitation and set the default number of pages to fit those 512 kiB + 1 page.

We cannot isolate the fix to symbol__new and symbol__delete since the private area is computed by subtracting the priv_size value from a "struct symbol" pointer, so then the private area can still be potentially unaligned.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Perf can't currently trace into the vsyscall page. It looks like it was meant to work. Tested on 2.6.38 and today's -git. The bug is easy to reproduce. Compile this: int main() { int i; struct timespec t; for(i = 0; i < 10000000; i++) clock_gettime(CLOCK_MONOTONIC, &t); return 0; } and run it through perf record; perf report. The top entry shows "[unknown]" and you can't zoom in. It looks like there are two issues. The first is a that a test for user mode executing in kernel space is backwards. (That's the first hunk below). The second (I think) is that something's wrong with the code that generates lots of little struct dso objects for different sections -- when it runs on vmlinux it results in bogus long_name values which cause objdump to fail.

| * | ktest: Fix bug where the test would not end after failureSteven Rostedt2011-03-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The config STOP_AFTER_FAILURE is the number of seconds to continue the test when a failure is detected. This lets the monitor record more data to the logs and console that may be helpful in solving the bug that was found. But the test had a bug. If the failure caused multiple "Call Trace" stack dumps, the start time to compare the STOP_AFTER_FAILURE would constantly be reset. Only update the start time at the first "Call Trace" instance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a during a git bisect, ktest fails on something other than what it is testing (if BISECT_TYPE is test but it fails on build), if BISECT_SKIP is set, then it will do a "git bisect skip" instead of just failing the bisect and letting the user find a good commit to test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For both git bisect and config bisect, if BISECT_MANUAL is set to 1, then bisect will stop between iterations and ask the user for the result. The actual result is ignored. This makes it possible to use ktest.pl for bisecting configs and git and let the user examine the results themselves and enter their own results.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When bisecting, one may come across a kernel that does not have make oldnoconfig. In this case, we need to run the command "yes" into a make oldconfig. This will select defaults instead of 'n' into each command, but it works as a work around. Note, "yes n" will not work because a config may have a value that "n" is not acceptable for. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we just look for a Call Trace to start the time out when to reboot the box. But if the kernel panics and does not show a Call Trace, the test will not reboot the box after the specified timeout. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
