2015-12-16perf list: Add support for PERF_COUNT_SW_BPF_OUTArnaldo Carvalho de Melo1-0/+4
When PERF_COUNT_SW_BPF_OUTPUT was added to the kernel we should've added it to tools/perf, where it is used just to list events. This ended up causing a segfault in commands like "perf list stall". Fix it by adding that new software counter. A patch to robustify perf to not segfault when the next counter gets added in the kernel will follow this one.

2015-12-15tools/power/acpi: Add userspace AML interface supportLv Zheng3-8/+473
This patch adds a userspace tool to access Linux kernel AML debugger interface. Tow modes are supported by this tool: 1. Interactive: Users are able to launch a debugging shell to talk with in-kernel AML debugger. Note that it's user duty to ensure kernel runtime integrity by using this debugging tool: A. Some control methods evaluated by the users may result in kernel panics if those control methods shouldn't be evaluated by the OSPMs according to the current BIOS/OS configurations. B. Currently if a single stepping evaluation couldn't run to an end, then the synchronization primitives acquired by the evaluation may block normal OSPM control method evaluations. 2. Batch: Users are able to execute debugger commands in a script. Note that in addition to the above duties, it's user duty to ensure script runtime integrity by using this debugging tool in this mode: C. Currently only those commands that are not used for single stepping are suitable to be used in this mode. D. If the execution of the command may cause a failure that could result in an endless kernel execution, the execution of the script may also get blocked. To exit the utility, currently "exit/quit" commands are recommended, but ctrl-C" can also be used. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

2015-12-07perf hists browser: Fix segfault if use symbol filter in cmdlineWang Nan1-0/+3
If feed perf a symbol filter in cmdline and the result is empty, pressing 'Enter' in the hist browser causes crash: # ./perf report perf.data <-- Common mistake for beginners Then press 'Enter': perf: Segmentation fault -------- backtrace -------- /home/wangnan/perf[0x53e578] /lib64/libc.so.6(+0x3545f)[0x7f76bafe045f] /home/wangnan/perf[0x539dd4] /home/wangnan/perf(perf_evlist__tui_browse_hists+0x96)[0x53d216] /home/wangnan/perf(cmd_report+0x1b9f)[0x442c7f] /home/wangnan/perf[0x47efa2] /home/wangnan/perf(main+0x5f5)[0x432fa5] /lib64/libc.so.6(__libc_start_main+0xf4)[0x7f76bafccbd4] /home/wangnan/perf[0x4330d4] This is because 'perf.data' is interpreted as a symbol filter, and the result is empty, so selection is empty. However, hist_browser__toggle_fold() forgets to check it. This patch simply return false when selection is NULL.

2015-12-07perf hists browser: Reset selection when refreshWang Nan1-0/+2
With the following steps: Step 1: perf report Step 2: Use UP/DOWN to select an entry, don't press 'ENTER' Step 3: Use '/' to filter symbols, use a filter which returns empty result Step 4: Press 'ENTER' We see that, even if we have filtered all the symbols (and the main interface is empty), pressing 'ENTER' still selects one symbol. This behavior surprises the user. This patch resets browser->{he_,}selection in hist_browser__refresh() and lets it choose default selection. In this case browser->{he_,}selection keeps NULL so user won't see annotation item in menu.

2015-12-07perf hists browser: Add NULL pointer check to prevent crashWang Nan1-0/+3
Before this patch we can trigger a segfault by following steps: Step 0: Use 'perf record' to generate a perf.data without callchain Step 1: perf report Step 2: Use UP/DOWN to select an entry, don't press 'ENTER' Step 3: Use '/' to filter symbols, use a filter which returns empty result Step 4: Press 'ENTER' (notice here that the old selection is still there. This is another problem) Step 5: Press 'ENTER' to annotate that symbol Step 6: Press 'LEFT' to go out. Result: segfault: perf: Segmentation fault -------- backtrace -------- /home/wangnan/perf[0x53e568] /lib64/libc.so.6(+0x3545f)[0x7fba75d3245f] /home/wangnan/perf[0x537516] /home/wangnan/perf[0x533fef] /home/wangnan/perf[0x53b347] /home/wangnan/perf(perf_evlist__tui_browse_hists+0x96)[0x53d206] /home/wangnan/perf(cmd_report+0x1b9f)[0x442c7f] /home/wangnan/perf[0x47efa2] /home/wangnan/perf(main+0x5f5)[0x432fa5] /lib64/libc.so.6(__libc_start_main+0xf4)[0x7fba75d1ebd4] /home/wangnan/perf[0x4330d4] This is because in this case 'nd' could be NULL in ui_browser__hists_seek(), but that function never checks it. This patch adds checker for potential NULL pointer in that function. After this patch the above steps won't segfault.

2015-12-07perf buildid-list: Show running kernel build id fixMichael Petlan1-1/+1
The --kernel option of perf buildid-list tool should show the running kernel buildid. The functionality has been lost during other changes of the related code. The build_id__sprintf() function should return length of the build-id string, but it was the length of the build-id raw data instead. Due to that, some return value checking caused that the final string was not printed out. With this patch the build_id__sprintf() returns the correct value, so the --kernel option works again.

2015-11-30nfit: Adjust for different _FIT and NFIT headersLinda Knippers1-34/+15
When support for _FIT was added, the code presumed that the data returned by the _FIT method is identical to the NFIT table, which starts with an acpi_table_header. However, the _FIT is defined to return a data in the format of a series of NFIT type structure entries and as a method, has an acpi_object header rather tahn an acpi_table_header. To address the differences, explicitly save the acpi_table_header from the NFIT, since it is accessible through /sys, and change the nfit pointer in the acpi_desc structure to point to the table entries rather than the headers.

2015-11-13perf probe: Clear probe_trace_event when add_probe_trace_event() failsWang Nan1-6/+14
When probing with a glob, errors in add_probe_trace_event() won't be passed to debuginfo__find_trace_events() because it would be modified by probe_point_search_cb(). It causes a segfault if perf fails to find an argument for a probe point matched by the glob.

2015-11-13perf symbols: Fix dso lookup by long name and missing buildidsAdrian Hunter3-0/+19
Commit 4598a0a6d22f ("perf symbols: Improve DSO long names lookup speed with rbtree") Added a tree to lookup dsos by long name. That tree gets corrupted whenever a dso long name is changed because the tree is not updated. One effect of that is buildid-list does not work with the 'with-hits' option because dso lookup fails and results in two structs for the same dso. The first has the buildid but no hits, the second has hits but no buildid. e.g. Before: $ tools/perf/perf record ls arch certs CREDITS Documentation firmware include ipc Kconfig lib Makefile net REPORTING-BUGS scripts sound usr block COPYING crypto drivers fs init Kbuild kernel MAINTAINERS mm README samples security tools virt [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.012 MB perf.data (11 samples) ] $ tools/perf/perf buildid-list 574da826c66538a8d9060d393a8866289bd06005 [kernel.kallsyms] 30c94dc66a1fe95180c3d68d2b89e576d5ae213c /lib/x86_64-linux-gnu/libc-2.19.so $ tools/perf/perf buildid-list -H 574da826c66538a8d9060d393a8866289bd06005 [kernel.kallsyms] 0000000000000000000000000000000000000000 /lib/x86_64-linux-gnu/libc-2.19.so After: $ tools/perf/perf buildid-list -H 574da826c66538a8d9060d393a8866289bd06005 [kernel.kallsyms] 30c94dc66a1fe95180c3d68d2b89e576d5ae213c /lib/x86_64-linux-gnu/libc-2.19.so The fix is to record the root of the tree on the dso so that dso__set_long_name() can update the tree when the long name changes.

2015-11-12perf symbols: Rebuild rbtree when adjusting symbols for kcoreAdrian Hunter1-16/+14
Normally symbols are read from the DSO and adjusted, if need be, so that the symbol start matches the file offset in the DSO file (we want the file offset because that is what we know from MMAP events). That is done by dso__load_sym() which inserts the symbols *after* adjusting them. In the case of kcore, the symbols have been read from kallsyms and the symbol start is the memory address. The symbols have to be adjusted to match the kcore file offsets. dso__split_kallsyms_for_kcore() does that, but now the adjustment is being done *after* the symbols have been inserted. It appears dso__split_kallsyms_for_kcore() was assuming that changing the symbol start would not change the order in the rbtree - which is, of course, not guaranteed.

2015-11-11perf probe: Verify parameters in two functionsWang Nan1-0/+6
On kernel with only one out of CONFIG_KPROBE_EVENTS and CONFIG_UPROBE_EVENTS enabled, 'perf probe -d' causes a segfault because perf_del_probe_events() calls probe_file__get_events() with a negative fd. This patch fixes it by adding parameter validation at the entry of probe_file__get_events() and probe_file__get_rawlist(). Since they are both non-static public functions (in .h file), parameter verifying is required. v1 -> v2: Verify fd at the head of probe_file__get_rawlist() instead of checking at call site (suggested by Masami and Arnaldo at [1,2]).
