Hi Ingo, Please consider pulling,
- Arnaldo Test results at the end of this message, as usual. The following changes since commit 02e184476eff848273826c1d6617bb37e5bcc7ad: perf/core: Force USER_DS when recording user stack data (2018-09-10 14:01:46 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-urgent-for-mingo-4.19-20180912 for you to fetch changes up to 03db8b583d1c3c84963e08e2abf6c79081da5c31: perf tools: Fix maps__find_symbol_by_name() (2018-09-11 14:12:51 -0300) ---------------------------------------------------------------- perf/urgent fixes: - Fix finding a symbol by name when multiple maps use the same backing DSO, so we must first see if that symbol name is in the DSO, then see if it is inside the range of addresses for that specific map (Adrian Hunter) - Update the tools copies of UAPI headers, which silences the warnings emitted when building the tools and in some cases, like for the new KVM ioctls, results in 'perf trace' being able to translate that ioctl number to a string (Arnaldo Carvalho de Melo) Signed-off-by: Arnaldo Carvalho de Melo <a...@redhat.com> ---------------------------------------------------------------- Adrian Hunter (1): perf tools: Fix maps__find_symbol_by_name() Arnaldo Carvalho de Melo (6): tools headers uapi: Update tools's copy of linux/perf_event.h tools headers uapi: Update tools's copy of asm-generic/unistd.h tools headers uapi: Update tools's copy of drm/drm.h tools headers uapi: Update tools's copies of kvm headers tools headers uapi: Update tools's copy of linux/vhost.h tools headers uapi: Update tools's copy of linux/if_link.h tools/arch/arm/include/uapi/asm/kvm.h | 13 ++++++++++++ tools/arch/arm64/include/uapi/asm/kvm.h | 13 ++++++++++++ tools/arch/s390/include/uapi/asm/kvm.h | 5 ++++- tools/arch/x86/include/uapi/asm/kvm.h | 37 +++++++++++++++++++++++++++++++++ tools/include/uapi/asm-generic/unistd.h | 4 +++- tools/include/uapi/drm/drm.h | 9 ++++++++ tools/include/uapi/linux/if_link.h | 17 +++++++++++++++ tools/include/uapi/linux/kvm.h | 6 ++++++ tools/include/uapi/linux/perf_event.h | 2 +- tools/include/uapi/linux/vhost.h | 18 ++++++++++++++++ tools/perf/util/map.c | 11 ++++++++++ 11 files changed, 132 insertions(+), 3 deletions(-) Test results: The first ones are container (docker) based builds of tools/perf with and without libelf support. 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. Get in contact if interested in helping having this in place. The alpine ones are failing due to a XSI/POSIX/GNU disagreement on how strerror_r() should be implemented, a fix is in the works to make libbpf to use the str_error_r() that tools/perf/ has been using to work on libraries such as MUSL, that Alpine Linux uses. This problem was not introduced by any patch in this series. # dm 1 alpine:3.4 : FAIL gcc (Alpine 5.3.0) 5.3.0 2 alpine:3.5 : FAIL gcc (Alpine 6.2.1) 6.2.1 20160822 3 alpine:3.6 : FAIL gcc (Alpine 6.3.0) 6.3.0 4 alpine:3.7 : FAIL gcc (Alpine 6.4.0) 6.4.0 5 alpine:3.8 : FAIL gcc (Alpine 6.4.0) 6.4.0 6 alpine:edge : FAIL gcc (Alpine 6.4.0) 6.4.0 libbpf.c: In function 'bpf_object__elf_init': libbpf.c:472:15: error: initialization makes pointer from integer without a cast [-Werror=int-conversion] char *cp = strerror_r(errno, errmsg, sizeof(errmsg)); 7 amazonlinux:1 : Ok gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28) 8 amazonlinux:2 : Ok gcc (GCC) 7.3.1 20180303 (Red Hat 7.3.1-5) 9 android-ndk:r12b-arm : Ok arm-linux-androideabi-gcc (GCC) 4.9.x 20150123 (prerelease) 10 android-ndk:r15c-arm : Ok arm-linux-androideabi-gcc (GCC) 4.9.x 20150123 (prerelease) 11 centos:5 : Ok gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-55) 12 centos:6 : Ok gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23) 13 centos:7 : Ok gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28) 14 debian:7 : Ok gcc (Debian 4.7.2-5) 4.7.2 15 debian:8 : Ok gcc (Debian 4.9.2-10+deb8u1) 4.9.2 16 debian:9 : Ok gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516 17 debian:experimental : Ok gcc (Debian 8.2.0-4) 8.2.0 18 debian:experimental-x-arm64 : Ok aarch64-linux-gnu-gcc (Debian 8.1.0-12) 8.1.0 19 debian:experimental-x-mips : Ok mips-linux-gnu-gcc (Debian 8.1.0-12) 8.1.0 20 debian:experimental-x-mips64 : Ok mips64-linux-gnuabi64-gcc (Debian 8.1.0-12) 8.1.0 21 debian:experimental-x-mipsel : Ok mipsel-linux-gnu-gcc (Debian 8.1.0-12) 8.1.0 22 fedora:20 : Ok gcc (GCC) 4.8.3 20140911 (Red Hat 4.8.3-7) 23 fedora:21 : Ok gcc (GCC) 4.9.2 20150212 (Red Hat 4.9.2-6) 24 fedora:22 : Ok gcc (GCC) 5.3.1 20160406 (Red Hat 5.3.1-6) 25 fedora:23 : Ok gcc (GCC) 5.3.1 20160406 (Red Hat 5.3.1-6) 26 fedora:24 : Ok gcc (GCC) 6.3.1 20161221 (Red Hat 6.3.1-1) 27 fedora:24-x-ARC-uClibc : Ok arc-linux-gcc (ARCompact ISA Linux uClibc toolchain 2017.09-rc2) 7.1.1 20170710 28 fedora:25 : Ok gcc (GCC) 6.4.1 20170727 (Red Hat 6.4.1-1) 29 fedora:26 : Ok gcc (GCC) 7.3.1 20180130 (Red Hat 7.3.1-2) 30 fedora:27 : Ok gcc (GCC) 7.3.1 20180712 (Red Hat 7.3.1-6) 31 fedora:28 : Ok gcc (GCC) 8.1.1 20180712 (Red Hat 8.1.1-5) 32 fedora:rawhide : Ok gcc (GCC) 8.2.1 20180801 (Red Hat 8.2.1-2) 33 gentoo-stage3-amd64:latest : Ok gcc (Gentoo 7.3.0-r3 p1.4) 7.3.0 34 mageia:5 : Ok gcc (GCC) 4.9.2 35 mageia:6 : Ok gcc (Mageia 5.5.0-1.mga6) 5.5.0 36 opensuse:13.2 : Ok gcc (SUSE Linux) 4.8.3 20140627 [gcc-4_8-branch revision 212064] 37 opensuse:42.1 : Ok gcc (SUSE Linux) 4.8.5 38 opensuse:42.2 : Ok gcc (SUSE Linux) 4.8.5 39 opensuse:42.3 : Ok gcc (SUSE Linux) 4.8.5 40 opensuse:tumbleweed : Ok gcc (SUSE Linux) 7.3.1 20180323 [gcc-7-branch revision 258812] 41 oraclelinux:6 : Ok gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23.0.1) 42 oraclelinux:7 : Ok gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28.0.1) 43 ubuntu:12.04.5 : Ok gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 44 ubuntu:14.04.4 : Ok gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4 45 ubuntu:14.04.4-x-linaro-arm64 : Ok aarch64-linux-gnu-gcc (Linaro GCC 5.5-2017.10) 5.5.0 46 ubuntu:16.04 : Ok gcc (Ubuntu 5.4.0-6ubuntu1~16.04.10) 5.4.0 20160609 47 ubuntu:16.04-x-arm : Ok arm-linux-gnueabihf-gcc (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 48 ubuntu:16.04-x-arm64 : Ok aarch64-linux-gnu-gcc (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 49 ubuntu:16.04-x-powerpc : Ok powerpc-linux-gnu-gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 50 ubuntu:16.04-x-powerpc64 : Ok powerpc64-linux-gnu-gcc (Ubuntu/IBM 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 51 ubuntu:16.04-x-powerpc64el : Ok powerpc64le-linux-gnu-gcc (Ubuntu/IBM 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 52 ubuntu:16.04-x-s390 : Ok s390x-linux-gnu-gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 53 ubuntu:16.10 : Ok gcc (Ubuntu 6.2.0-5ubuntu12) 6.2.0 20161005 54 ubuntu:17.10 : Ok gcc (Ubuntu 7.2.0-8ubuntu3.2) 7.2.0 55 ubuntu:18.04 : Ok gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0 56 ubuntu:18.04-x-arm : Ok arm-linux-gnueabihf-gcc (Ubuntu/Linaro 7.3.0-16ubuntu3) 7.3.0 57 ubuntu:18.04-x-arm64 : Ok aarch64-linux-gnu-gcc (Ubuntu/Linaro 7.3.0-16ubuntu3) 7.3.0 58 ubuntu:18.04-x-m68k : Ok m68k-linux-gnu-gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0 59 ubuntu:18.04-x-powerpc : Ok powerpc-linux-gnu-gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0 60 ubuntu:18.04-x-powerpc64 : Ok powerpc64-linux-gnu-gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0 61 ubuntu:18.04-x-powerpc64el : Ok powerpc64le-linux-gnu-gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0 62 ubuntu:18.04-x-riscv64 : Ok riscv64-linux-gnu-gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0 63 ubuntu:18.04-x-s390 : Ok s390x-linux-gnu-gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0 64 ubuntu:18.04-x-sh4 : Ok sh4-linux-gnu-gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0 65 ubuntu:18.04-x-sparc64 : Ok sparc64-linux-gnu-gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0 66 ubuntu:18.10 : Ok gcc (Ubuntu 8.2.0-4ubuntu1) 8.2.0 #
