2016-12-14build: add support for x86_64 hostSeung-Woo Kim
For x86_64 host local build, this patch adds prebuilt mkimage from u-boot and local build script files uses the prebuilt mkimage as host architecture. The mkimage requires dtc also, but it is already in scripts/dtc and built as host tool during kernel build,so dtc is not required prebuilt files.

2016-12-14kmsg: selftestsPaul Osmialowski
This patch adds selftests framework and four test scenarios for kmsg. The framework shape and code was inspired by similar selftests framework for kdbus. Change-Id: I4453105186c90430dcdb59d592392fbac05b42f5 Signed-off-by: Paul Osmialowski <p.osmialowsk@samsung.com>
2016-12-14kdbus: Ability to run kdbus test by executable binary namePaul Osmialowski
With this applied, you can do following: $ cp kdbus-test daemon $ cp kdbus-test send Then run 'daemon' in one shell session: $ ./daemon --bus test ...and 'send' in another: $ ./send --bus test Useful for testing features introduced by previous patches. Signed-off-by: Paul Osmialowski <p.osmialowsk@samsung.com>
2016-12-14kdbus: selftests extendedPaul Osmialowski
The 'test-send' test case should connect to an already running test-daemon which creates a bus with known name. The main goal of this test case is to verify that messages as well as file descriptors (opened with different open modes) can be transferred properly. In order to achieve its goals, this test case opens three files (/tmp/kdbus-test-send.rd, /tmp/kdbus-test-send.wr, /tmp/kdbus-test-send.rdwr) with three different open modes (O_RDONLY, O_WRONLY, O_RDWR). If any of these files exists it is used 'as is', otherwise it is created with some default content. Then this test tries to send simple message followed by three messages each one of them containing an array of opened file descriptors (single element array in the first message, two element array in the second, three element array in the third). The ability to send array of file descriptors required changes in almost all of the test case files.

2016-12-14kdbus: TEST_CREATE_CONN now does no depend on TEST_CREATE_BUSPaul Osmialowski
Without this patch, it is impossible to specify test case able to connect to a bus already created (e.g. by 'test-daemon' test case), you can only specify: 1) TEST_CREATE_BUS which creates new bus, or 2) TEST_CREATE_CONN OR'ed with TEST_CREATE_BUS which creates new bus and creates connection to it. This patch adds the missing ability to specify TEST_CREATE_CONN alone. It will be used by a new test case (will be added by separate commit) which is supposed to connect to already started test-daemon case. Signed-off-by: Paul Osmialowski <p.osmialowsk@samsung.com>

This patch adds an extensive test suite for kdbus that checks the most important code paths in the driver. The idea is to extend the test suite over time.

2016-05-17tools lib traceevent: Do not reassign parg after collapse_tree()Steven Rostedt
[ Upstream commit 106b816cb46ebd87408b4ed99a2e16203114daa6 ] At the end of process_filter(), collapse_tree() was changed to update the parg parameter, but the reassignment after the call wasn't removed. What happens is that the "current_op" gets modified and freed and parg is assigned to the new allocated argument. But after the call to collapse_tree(), parg is assigned again to the just freed "current_op", and this causes the tool to crash. The current_op variable must also be assigned to NULL in case of error, otherwise it will cause it to be free()ed twice.

2016-04-11efi: Make efivarfs entries immutable by defaultPeter Jones
[ Upstream commit ed8b0de5a33d2a2557dce7f9429dca8cb5bc5879 ] "rm -rf" is bricking some peoples' laptops because of variables being used to store non-reinitializable firmware driver data that's required to POST the hardware. These are 100% bugs, and they need to be fixed, but in the mean time it shouldn't be easy to *accidentally* brick machines. We have to have delete working, and picking which variables do and don't work for deletion is quite intractable, so instead make everything immutable by default (except for a whitelist), and make tools that aren't quite so broad-spectrum unset the immutable flag.

2016-02-03perf kvm record/report: 'unprocessable sample' error while ↵Ravi Bangoria
recording/reporting guest data [ Upstream commit 3caeaa562733c4836e61086ec07666635006a787 ] While recording guest samples in host using perf kvm record, it will populate unprocessable sample error, though samples will be recorded properly. While generating report using perf kvm report, no samples will be processed and same error will populate. We have seen this behaviour with upstream perf(4.4-rc3) on x86 and ppc64 hardware. Reason behind this failure is, when it tries to fetch machine from rb_tree of machines, it fails. As a part of tracing a bug, we figured out that this code was incorrectly refactored in commit 54245fdc3576 ("perf session: Remove wrappers to machines__find"). This patch will change the functionality such that if it can't fetch machine in first trial, it will create one node of machine and add that to rb_tree. So next time when it tries to fetch same machine from rb_tree, it won't fail. Actually it was the case before refactoring of code in aforementioned commit. This patch is generated from acme perf/core branch. Below I've mention an example that demonstrate the behaviour before and after applying patch. Before applying patch: [Note: One needs to run guest before recording data in host] ravi@ravi-bangoria:~$ ./perf kvm record -a Warning: 5903 unprocessable samples recorded.

We can't update it when obtaining a line value for a column (for instance, in sort__srcline_cmp()), because we reset it all when doing a resort (see hists__output_recalc_col_len()), so we need to, from what is in the hist_entry fields, set each of the column widths.

2015-10-22perf tools: Fix copying of /proc/kcoreAdrian Hunter
commit b5cabbcbd157a4bf5a92dfc85134999a3b55342d upstream. A copy of /proc/kcore containing the kernel text can be made to the buildid cache. e.g. perf buildid-cache -v -k /proc/kcore To workaround objdump limitations, a copy is also made when annotating against /proc/kcore. The copying process stops working from libelf about v1.62 onwards (the problem was found with v1.63). The cause is that a call to gelf_getphdr() in kcore__add_phdr() fails because additional validation has been added to gelf_getphdr(). The use of gelf_getphdr() is a misguided attempt to get default initialization of the Gelf_Phdr structure. That should not be necessary because every member of the Gelf_Phdr structure is subsequently assigned. So just remove the call to gelf_getphdr(). Similarly, a call to gelf_getehdr() in gelf_kcore__init() can be removed also. Committer notes: Note to stable@kernel.org, from Adrian in the cover letter for this patchkit: The "Fix copying of /proc/kcore" problem goes back to v3.13 if you think it is important enough for stable.

2015-08-10perf symbols: Store if there is a filter in placeArnaldo Carvalho de Melo
commit 0bc2f2f7d080561cc484d2d0a162a9396bed3383 upstream. 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.

2015-08-10perf hists browser: Take the --comm, --dsos, etc filters into accountArnaldo Carvalho de Melo
commit 9c0fa8dd3d58de8b688fda758eea1719949c7f0a upstream. 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.

Linux-3.7 added CONFIG_BOOTPARAM_HOTPLUG_CPU0, allowing systems to offline cpu0. But when cpu0 is offline, turbostat will not run: # turbostat ls turbostat: no /dev/cpu/0/msr This patch replaces the hard-coded use of cpu0 in turbostat with the current cpu, allowing it to run without a cpu0. Fewer cross-calls may also be needed due to use of current cpu, though this hard-coding was used only for the --debug preamble.

With recent debugging, I noticed that bpf_jit_disasm segfaults when there's no debugging output from the JIT compiler to the kernel log. Reason is that when regexec(3) doesn't match on anything, start/end offsets are not being filled out and contain some uninitialized garbage from stack. Thus, we need zero out offsets first.
