by Arnaldo Carvalho de Melo

From: Arnaldo Carvalho de Melo <acme(a)redhat.com> Hi Ingo, Please consider pulling, - Arnaldo Test results at the end of this message, as usual. The following changes since commit 7869e5889477e4e32e4024d665431b35e8b7b693: Merge remote-tracking branch 'tip/perf/urgent' into perf/core (2018-06-04 10:28:20 -0300) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-4.18-20180605 for you to fetch changes up to 03ac4e71cd120d2c3411d106d00d266114575f74: perf intel-pt: Fix "Unexpected indirect branch" error (2018-06-05 12:28:52 -0300) ---------------------------------------------------------------- perf/core improvements and fixes: perf stat: . Display user and system time for workload targets (Jiri Olsa) perf record: . Enable arbitrary event names thru name= modifier (Alexey Budankov) PowerPC: . Add a python script for hypervisor call statistics (Ravi Bangoria) Intel PT: (Adrian Hunter) . Fix sync_switch INTEL_PT_SS_NOT_TRACING . Fix decoding to accept CBR between FUP and corresponding TIP . Fix MTC timing after overflow . Fix "Unexpected indirect branch" error perf test: . record+probe_libc_inet_pton: . To get the symbol table for dynamic shared objects on ubuntu we need to pass the -D/--dynamic command line option, unlike with the fedora distros (Arnaldo Carvalho de Melo) . code-reading: . Fix perf_env setup for PTI entry trampolines (Adrian Hunter) . kmod-path: . Add tests for vdso32 and vdsox32 (Adrian Hunter) . Use header file util/debug.h (Thomas Richter) perf annotate: . Make the various UI backends (stdio, TUI, gtk) use more consistently structs with annotation options as specified by the user (Arnaldo Carvalho de Melo) . Move annotation specific knobs from the symbol_conf global kitchen sink to the annotation option structs (Arnaldo Carvalho de Melo) Core: . Fix misleading error for some unparsable events mentioning PMUs when those are not involved in the problem (Jiri Olsa) - Fix symbol and object code resolution for vdso32 and vdsox32 (Adrian Hunter) . No need to check for null when passing pointers to foo__get() style refcount grabbing helpers, just like in the kernel and with free(), its safe to pass a NULL pointer to avoid having to check it before each and every foo__get() call (Arnaldo Carvalho de Melo) . Remove some dead code (quote.[ch]) (Arnaldo Carvalho de Melo) . Remove some needless globals, making them local (Arnaldo Carvalho de Melo) . Reduce usage of symbol_conf.use_callchain, using other means of finding out if callchains are in use or available for specific events, as we evolved this codebase to allow requesting callchains for just a subset of the monitored events. In time it will help polish recording and showing mixed sets accross the various tools: perf record -e cycles/call-graph=fp/,cache-misses/call-graph=dwarf/,instructions (Arnaldo Carvalho de Melo) . Consider PTI entry trampolines in map__rip_2objdump() (Adrian Hunter) Signed-off-by: Arnaldo Carvalho de Melo <acme(a)redhat.com> ---------------------------------------------------------------- Adrian Hunter (8): perf tests kmod-path: Add tests for vdso32 and vdsox32 perf tools: Fix symbol and object code resolution for vdso32 and vdsox32 perf test code-reading: Fix perf_env setup for PTI entry trampolines perf map: Consider PTI entry trampolines in rip_2objdump() perf intel-pt: Fix sync_switch INTEL_PT_SS_NOT_TRACING perf intel-pt: Fix decoding to accept CBR between FUP and corresponding TIP perf intel-pt: Fix MTC timing after overflow perf intel-pt: Fix "Unexpected indirect branch" error Alexey Budankov (1): perf record: Enable arbitrary event names thru name= modifier Arnaldo Carvalho de Melo (33): perf tools: Remove dead quote.[ch] code perf probe: Use return of map__get() to make code more compact perf cgroup: Make evlist__find_cgroup() more compact perf tools: No need to check if the argument to __get() function is NULL perf annotate: Pass perf_evsel instead of just evsel->idx perf annotate: __symbol__acount_cycles doesn't need notes perf annotate: Split allocation of annotated_source struct perf annotate: Introduce constructor/destructor for annotated_source perf annotate: Introduce annotated_source__alloc_histograms perf annotate: __symbol__inc_addr_samples() needs just annotated_source perf annotate: Introduce symbol__hists() perf annotate: Introduce symbol__cycle_hists() perf annotate: Stop using symbol_conf.nr_events global in symbol__hists() perf annotate: Replace symbol__alloc_hists() with symbol__hists() perf tools: Ditch the symbol_conf.nr_events global perf annotate: Add comment about annotated_src->nr_histograms perf annotate stdio: Use annotation_options consistently perf srcline: Introduce map__srcline() to make code more compact perf sort: Introduce addr_map_symbol__srcline() to make code more compact perf srcline: Make hist_entry srcline helper consistent with map's perf annotate: Pass annotation_options to symbol__annotate() perf annotate: Adopt anotation options from symbol_conf perf annotate: Move disassembler_style global to annotation_options perf hists browser: Pass annotation_options from tool to browser perf annotate: Move objdump_path to struct annotation_options perf report: No need to have report_callchain_help as a global perf evsel: Add has_callchain() helper to make code more compact/clear perf script: Check if evsel has callchains before trying to use it perf sched: Use sched->show_callchain where appropriate perf hists: Do not allocate space for callchains for evsels without them perf hists: Introduce hist_entry__has_callchain() method perf hists: Check if a hist_entry has callchains before using them perf test record+probe_libc_inet_pton: Ask 'nm' for dynamic symbols Jiri Olsa (2): perf stat: Display user and system time perf tools: Fix pmu events parsing rule Ravi Bangoria (1): perf script powerpc: Python script for hypervisor call statistics Thomas Richter (1): perf test: Use header file util/debug.h tools/perf/Documentation/perf-list.txt | 6 +- tools/perf/Documentation/perf-record.txt | 3 + tools/perf/Documentation/perf-stat.txt | 40 +++-- tools/perf/arch/common.c | 4 +- tools/perf/arch/common.h | 4 +- tools/perf/builtin-annotate.c | 36 ++-- tools/perf/builtin-c2c.c | 2 +- tools/perf/builtin-kvm.c | 2 -

Where clang is available, it is also used to build perf with/without libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang when clang and its devel libraries are installed. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure.

[char-misc 2/2] mei: discard messages from not connected client during power down.

by Tomas Winkler

From: Alexander Usyskin <alexander.usyskin(a)intel.com> This fixes regression introduced by commit 8d52af6795c0 ("mei: speed up the power down flow") In power down or suspend flow a message can still be received from the FW because the clients fake disconnection. In normal case we interpret messages w/o destination as corrupted and link reset is performed in order to clean the channel, but during power down link reset is already in progress resulting in endless loop. To resolve the issue under power down flow we discard messages silently.

[PATCH] ARC: Remove CONFIG_INITRAMFS_SOURCE from defconfigs

by Alexey Brodkin

We used to have pre-set CONFIG_INITRAMFS_SOURCE with local path to intramfs in ARC defconfigs. This was quite convenient for in-house development but not that convenient for newcomers who obviusly don't have folders like "arc_initramfs" next to the Linux source tree. Which leads to quite surprising failure of defconfig building: ------------------------------->8----------------------------- ../scripts/gen_initramfs_list.sh: Cannot open '../../arc_initramfs_hs/' ../usr/Makefile:57: recipe for target 'usr/initramfs_data.cpio.gz' failed make[2]: *** [usr/initramfs_data.cpio.gz] Error 1 ------------------------------->8----------------------------- So now when more and more people start to deal with our defconfigs let's make their life easier with removal of CONFIG_INITRAMFS_SOURCE.

[PATCH v13 1/3] ioremap: Update pgtable free interfaces with addr

by Chintan Pandya

From: Chintan Pandya <cpandya(a)codeaurora.org> The following kernel panic was observed on ARM64 platform due to a stale TLB entry. 1. ioremap with 4K size, a valid pte page table is set. 2. iounmap it, its pte entry is set to 0. 3. ioremap the same address with 2M size, update its pmd entry with a new value. 4. CPU may hit an exception because the old pmd entry is still in TLB, which leads to a kernel panic. Commit b6bdb7517c3d ("mm/vmalloc: add interfaces to free unmapped page table") has addressed this panic by falling to pte mappings in the above case on ARM64. To support pmd mappings in all cases, TLB purge needs to be performed in this case on ARM64. Add a new arg, 'addr', to pud_free_pmd_page() and pmd_free_pte_page() so that TLB purge can be added later in seprate patches.

[PATCH 1/9] dm-integrity: change the variable suspending from bool to int

by Mikulas Patocka

The early alpha processors can't write a byte or short atomically - they read 8 bytes, modify the byte or two bytes in registers and write back 8 bytes. The modification of the variable "suspending" may race with modification of the variable "failed". This patch changes suspending to an int.

netfilter: nf_flow_table: attach dst to skbs

by Jason A. Donenfeld

Some drivers, such as vxlan and wireguard, use the skb's dst in order to determine things like PMTU. They therefore loose functionality when flow offloading is enabled. So, we ensure the skb has it before xmit'ing it in the offloading path. Signed-off-by: Jason A.
