git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/urgent fixes from Arnaldo Carvalho de Melo: - Fix buildid processing done at the end of a 'perf record' session, a problem that happened in workloads involving lots of small short-lived processes. That code was not asking the perf_session layer to order the events. Make the code more robust to handle some of the problems with such out-of-order events and fix 'perf record' to ask for ordered events on systems where we have perf_event_attr.sample_id_all.

2015-08-19perf tools: Make fork event processing more resilientAdrian Hunter
When processing a fork event, the tools lookup the parent thread by its tid. In a couple of cases, it is possible for that thread to have the wrong pid. That can happen if the data is being processed out of order, or if the (fork) event that would have removed the erroneous thread was lost. Assume the latter case, print a dump message, remove the erroneous thread, create a new one with the correct pid, and keep going.

When building with a prefix ending with a slash, for example: $ make prefix=/usr/local/ one of the perf tests fail to compile due to BUILD_STR macro mishandling bindir_SQ string containing with two slashes: -DBINDIR="BUILD_STR(/usr/local//bin)" with the following error: CC tests/attr.o tests/attr.c: In function ‘test__attr’: tests/attr.c:168:50: error: expected ‘)’ before ‘;’ token snprintf(path_perf, PATH_MAX, "%s/perf", BINDIR); ^ tests/attr.c:176:1: error: expected ‘;’ before ‘}’ token } ^ tests/attr.c:176:1: error: control reaches end of non-void function [-Werror=return-type] } ^ cc1: all warnings being treated as errors This patch works around the problem by "cleaning" the bindir string using make's abspath function.

The transaction length metrics in perf stat -T broke recently. It would not match the metric correctly and always print K/sec. This was caused by a incorrect update of the cycles_in_tx statistics. Update the correct variable. Also the check for zero division was reversed, which resulted in K/sec being printed for no transactions. Fix this also up.

2015-07-15perf tools: Really allow to specify custom CC, AR or LDAlexey Brodkin
Commit 5ef7bbb09f7b ("perf tools: Allow to specify custom linker command") was meant to enable usage non $(CROSS_COMPILE)ld linker during perf building. But implementation didn't take into account the fact that LD is a pre-defined variable in GNU Make. I.e. it is always defined. Which means there's no point to check "LD ?= ..." because it will never succeed. And so LD will be either that explicitly passed to make like this: ------->8------- make LD=path_to_my_ld ... ------->8------- or default value, which is host's "ld". Latter leads to failure of cross-linkage because instead of cross linker "$(CROSS_COMPILE)ld" host's "ld" is used. Fortunately there's a way to do correct substitution of $(CROSS_COMPILE)ld with user defined LD on command-line. As a reference was used implementation in "tools/lib/traceevent/Makefile". Build tested for x86_64 and ARC. Thanks Jiri for this hint.

2015-07-13perf hists browser: Take the --comm, --dsos, etc filters into accountArnaldo Carvalho de Melo
At some point: commit 2c86c7ca7606 Author: Namhyung Kim <namhyung@kernel.org> Date: Mon Mar 17 18:18:54 2014 -0300 perf report: Merge al->filtered with hist_entry->filtered We stopped dropping samples for things filtered via the --comms, --dsos, --symbols, etc, i.e. things marked as filtered in the symbol resolution routines (thread__find_addr_map(), perf_event__preprocess_sample(), etc). But then, in: commit 268397cb2a47 Author: Namhyung Kim <namhyung@kernel.org> Date: Tue Apr 22 14:49:31 2014 +0900 perf top/tui: Update nr_entries properly after a filter is applied We don't take into account entries that were filtered in perf_event__preprocess_sample() and friends, which leads to inconsistency in the browser seek routines, that expects the number of hist_entry->filtered entries to match what it thinks is the number of unfiltered, browsable entries. So, for instance, when we do: perf top --symbols ___non_existent_symbol___ the hist_browser__nr_entries() routine thinks there are no filters in place, uses the hists->nr_entries but all entries are filtered, leading to a segfault. Tested with: perf top --symbols malloc,free --percentage=relative Freezing, by pressing 'f', at any time and doing the math on the percentages ends up with 100%, ditto for: perf top --dsos libpthread-2.20.so,libxul.so --percentage=relative Both were segfaulting, all fixed now. More work needed to do away with checking if filters are in place, we should just use the nr_non_filtered_samples counter, no need to conditionally use it or hists.nr_filter, as what the browser does is just show unfiltered stuff. An audit of how it is being accounted is needed, this is the minimal fix.

2015-07-13perf symbols: Store if there is a filter in placeArnaldo Carvalho de Melo
When setting yup the symbols library we setup several filter lists, for dsos, comms, symbols, etc, and there is code that, if there are filters, do certain operations, like recalculate the number of non filtered histogram entries in the top/report TUI. But they were considering just the "Zoom" filters, when they need to take into account as well the above mentioned filters (perf top --comms, --dsos, etc). So store in symbol_conf.has_filter true if any of those filters is in place.

2015-07-09perf thread_map: Fix the sizeof() calculation for map entriesArnaldo Carvalho de Melo
When we started adding extra stuff per array entry, growing the size of those entries to more than sizeof(pid_t), we had to convert those sizeof operations to the more robust sizeof(map->map[0]) idiom, that is future proof, i.e. if/when we add more stuff to those entries, that expression will produce the new per-entry size. And besides that, we need to zero out those extra fields, that sometimes may not get filled, like when we couldn't care less about the comms, since we don't need those, but since we will try freeing it at thread_map__delete(), we better fix it. That is why a thread_map__realloc() was provided. But that method wasn't used in thread_map__new_by_uid(), fix it.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPICA updates from Rafael Wysocki: "Additional ACPICA material for v4.2-rc1 This will update the ACPICA code in the kernel to upstream revision 20150619 (a bug-fix release mostly including stable-candidate fixes) and restore an earlier ACPICA commit that had to be reverted due to a regression introduced by it (the regression is addressed by blacklisting the only known system affected by it to date). The only new feature added by this update is the support for overriding objects in the ACPI namespace and a new ACPI table that can be used for that called the Override System Definition Table (OSDT). That should allow us to "patch" the ACPI namespace built from incomplete or incorrect ACPI System Definition tables (DSDT, SSDT) during system startup without the need to provide replacements for all of those tables in the future.

git://git.kernel.org/pub/scm/linux/kernel/git/djbw/nvdimm Pull libnvdimm subsystem from Dan Williams: "The libnvdimm sub-system introduces, in addition to the libnvdimm-core, 4 drivers / enabling modules: NFIT: Instantiates an "nvdimm bus" with the core and registers memory devices (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware Interface table). After registering NVDIMMs the NFIT driver then registers "region" devices. A libnvdimm-region defines an access mode and the boundaries of persistent memory media. A region may span multiple NVDIMMs that are interleaved by the hardware memory controller. In turn, a libnvdimm-region can be carved into a "namespace" device and bound to the PMEM or BLK driver which will attach a Linux block device (disk) interface to the memory. PMEM: Initially merged in v4.1 this driver for contiguous spans of persistent memory address ranges is re-worked to drive PMEM-namespaces emitted by the libnvdimm-core. In this update the PMEM driver, on x86, gains the ability to assert that writes to persistent memory have been flushed all the way through the caches and buffers in the platform to persistent media. See memcpy_to_pmem() and wmb_pmem(). BLK: This new driver enables access to persistent memory media through "Block Data Windows" as defined by the NFIT. The primary difference of this driver to PMEM is that only a small window of persistent memory is mapped into system address space at any given point in time. Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access different portions of the media. BLK-mode, by definition, does not support DAX. BTT: This is a library, optionally consumed by either PMEM or BLK, that converts a byte-accessible namespace into a disk with atomic sector update semantics (prevents sector tearing on crash or power loss). The sinister aspect of sector tearing is that most applications do not know they have a atomic sector dependency. At least today's disk's rarely ever tear sectors and if they do one almost certainly gets a CRC error on access. NVDIMMs will always tear and always silently. Until an application is audited to be robust in the presence of sector-tearing the usage of BTT is recommended.
