[GIT PULL 00/27] perf/core improvements and fixes

by Arnaldo Carvalho de Melo

Hi Ingo, Please consider pulling, I'm now investigating why these failed: 38: LLVM search and compile : 38.1: Basic BPF llvm compile : Ok 38.2: kbuild searching : Ok 38.3: Compile source for BPF prologue generation : Ok 38.4: Compile source for BPF relocation : FAILED! 40: BPF filter : 40.1: Basic BPF filtering : Ok 40.2: BPF pinning : Ok 40.3: BPF prologue generation : Ok 40.4: BPF relocation checker : FAILED! I think these failures are not related to changes in this patch kit. Details about the test environment, versions, etc. Regards, - Arnaldo Test results at the end of this message, as usual. The following changes since commit 1d59d16e9b4d5be80c9786a8b129c0f2af0e9522: Merge remote-tracking branch 'tip/perf/urgent' into perf/core (2018-07-24 14:34:32 -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-4.19-20180725 for you to fetch changes up to 9ef0112442bdddef5fb55adf20b3a5464b33de75: perf test: Fix subtest number when showing results (2018-07-24 14:55:51 -0300) ---------------------------------------------------------------- perf/cores fixes and improvements: Tools: top: -

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.

[PATCH 4.17 00/63] 4.17.10-stable review

This is the start of the stable review cycle for the 4.17.10 release. There are 63 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let me know. Responses should be made by Wed Jul 25 12:24:28 UTC 2018. Anything received after that time might be too late. The whole patch series can be found in one patch at: https://www.kernel.org/pub/linux/kernel/v4.x/stable-review/patch-4.17.10-rc… or in the git tree and branch at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-4.17.y and the diffstat can be found below. thanks, greg k-h ------------- Pseudo-Shortlog of commits: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Linux 4.17.10-rc1 Mathias Nyman <mathias.nyman(a)linux.intel.com> xhci: Fix perceived dead host due to runtime suspend race with event handler Al Viro <viro(a)zeniv.linux.org.uk> cxl_getfile(): fix double-iput() on alloc_file() failures Al Viro <viro(a)zeniv.linux.org.uk> drm_mode_create_lease_ioctl(): fix open-coded filp_clone_open() Al Viro <viro(a)ZenIV.linux.org.uk> alpha: fix osf_wait4() breakage Alexander Couzens <lynxis(a)fe80.eu> net: usb: asix: replace mii_nway_restart in resume path Sabrina Dubroca <sd(a)queasysnail.net> ipv6: make DAD fail with enhanced DAD when nonce length differs Florian Fainelli <f.fainelli(a)gmail.com> net: systemport: Fix CRC forwarding check for SYSTEMPORT Lite Saeed Mahameed <saeedm(a)mellanox.com> net/mlx4_en: Don't reuse RX page when XDP is set Igor Russkikh <igor.russkikh(a)aquantia.com> net: aquantia: vlan unicast address list correct handling Haiyang Zhang <haiyangz(a)microsoft.com> hv_netvsc: Fix napi reschedule while receive completion is busy Xin Long <lucien.xin(a)gmail.com> sctp: fix the issue that pathmtu may be set lower than MINSEGMENT Marcelo Ricardo Leitner <marcelo.leitner(a)gmail.com> sctp: introduce sctp_dst_mtu Prashant Bhole <bhole_prashant_q7(a)lab.ntt.co.jp> net: ip6_gre: get ipv6hdr after skb_cow_head() Sanjeev Bansal <sanjeevb.bansal(a)broadcom.com> tg3: Add higher cpu clock for 5762.

[PATCH] drm/vc4: Reset ->{x, y}_scaling[1] when dealing with uniplanar formats

This is needed to ensure ->is_unity is correct when the plane was previously configured to output a multi-planar format with scaling enabled, and is then being reconfigured to output a uniplanar format.

[PATCH v2] drm/atomic: Initialize variables in drm_atomic_helper_async_check() to make gcc happy

by Boris Brezillon

drm_atomic_helper_async_check() declares the plane, old_plane_state and new_plane_state variables to iterate over all planes of the atomic state and make sure only one plane is enabled. Unfortunately gcc is not smart enough to figure out that the check on n_planes is enough to guarantee that plane, new_plane_state and old_plane_state are initialized. Explicitly initialize those variables to NULL to make gcc happy.

[PATCH v2] drm/atomic: Check old_plane_state->crtc in drm_atomic_helper_async_check()

by Boris Brezillon

Async plane update is supposed to work only when updating the FB or FB position of an already enabled plane. That does not apply to requests where the plane was previously disabled or assigned to a different CTRC. Check old_plane_state->crtc value to make sure async plane update is allowed.
