It appears that the single port Ether controllers having TSU (like SH7734/ R8A7740) need the same kind of treating in sh_eth_tsu_init() as R7S72100 currently has -- they also don't have the TSU registers related e.g. to passing the frames between ports. Add the 'sh_eth_cpu_data::dual_port' flag and use it as a new criterion for taking a "short path" in the TSU init sequence in order to avoid writing to the non-existent registers...

The TSU_QTAG0/1 registers found in the Gigabit Ether controllers actually have the same long name as the TSU_QTAGM0/1 registers in the early Ether controllers: Qtag Addition/Deletion Set Register (Port 0/1 to 1/0); thus there's no need to make a difference in sh_eth_tsu_init() between those controllers. Unfortunately, we can't just remove TSU_QTAG0/1 from the register *enum* because that would break the ethtool register dump...

Andrew Lunn says: ==================== mv88e6xxx: Poll when no interrupt defined Not all boards using the mv88e6xxx switches have the interrupt output connected to a GPIO. On these boards phylib has to poll the PHYs, rather than use interrupts. Have the driver poll the interrupt status register, which is more efficient than having phylib do it. And it enables other switch interrupts to be services. The Armada 370RD is such a board without a interrupt GPIO. Now that interrupts work, wire up the PHYs to make use if them. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Not all boards have the interrupt output from the switch connected to a GPIO line. In such cases, phylib has to poll the internal PHYs, rather than receive an interrupt when there is a change in the link state. phylib polls once per second, and per PHY reads around 4 words. With a switch typically having 4 internal PHYs, this means 16 MDIO transactions per second. Rather than performing this phylib level polling, have the driver poll the interrupt status register. If the status register indicates an interrupt condition processing of interrupts in the same way as if a GPIO was used. Polling 10 times a second places less load on the MDIO bus. But rather than taking on average 0.5s to detect a link change, it takes less than 0.05s. Additionally, other interrupts, such as the watchdog, ATU and VTU violations will be reported.

Up until now we only allowed VLAN devices to be put in a VLAN-unaware bridge, but some users need the ability to enslave physical ports as well. This is achieved by mapping the port and VID 1 to the bridge's vFID, instead of the port and the VID used by the VLAN device. The above is valid because as long as the port is not enslaved to a bridge, VID 1 is guaranteed to be configured as PVID and egress untagged.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-02-26 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Various improvements for BPF kselftests: i) skip unprivileged tests when kernel.unprivileged_bpf_disabled sysctl knob is set, ii) count the number of skipped tests from unprivileged, iii) when a test case had an unexpected error then print the actual but also the unexpected one for better comparison, from Joe. 2) Add a sample program for collecting CPU state statistics with regards to how long the CPU resides in cstate and pstate levels. Based on cpu_idle and cpu_frequency trace points, from Leo. 3) Various x64 BPF JIT optimizations to further shrink the generated image size in order to make it more icache friendly. When tested on the Cilium generated programs, image size reduced by approx 4-5% in best case mainly due to how LLVM emits unsigned 32 bit constants, from Daniel. 4) Improvements and fixes on the BPF sockmap sample programs: i) fix the sockmap's Makefile to include nlattr.o for libbpf, ii) detach the sock ops programs from the cgroup before exit, from Prashant. 5) Avoid including xdp.h in filter.h by just forward declaring the struct xdp_rxq_info in filter.h, from Jesper. 6) Fix the BPF kselftests Makefile for cgroup_helpers.c by only declaring it a dependency for test_dev_cgroup.c but not every other test case where it is not needed, from Jesper. 7) Adjust rlimit RLIMIT_MEMLOCK for test_tcpbpf_user selftest since the default is insufficient for creating the 'global_map' used in the corresponding BPF program, from Yonghong. 8) Likewise, for the xdp_redirect sample, Tushar ran into the same when invoking xdp_redirect and xdp_monitor at the same time, therefore in order to have the sample generically work bump the limit here, too. Fix from Tushar. 9) Avoid an unnecessary NULL check in BPF_CGROUP_RUN_PROG_INET_SOCK() since sk is always guaranteed to be non-NULL, from Yafang. ==================== Signed-off-by: NDavid S.

CPU is active when have running tasks on it and CPUFreq governor can select different operating points (OPP) according to different workload; we use 'pstate' to present CPU state which have running tasks with one specific OPP. On the other hand, CPU is idle which only idle task on it, CPUIdle governor can select one specific idle state to power off hardware logics; we use 'cstate' to present CPU idle state. Based on trace events 'cpu_idle' and 'cpu_frequency' we can accomplish the duration statistics for every state. Every time when CPU enters into or exits from idle states, the trace event 'cpu_idle' is recorded; trace event 'cpu_frequency' records the event for CPU OPP changing, so it's easily to know how long time the CPU stays in the specified OPP, and the CPU must be not in any idle state. This patch is to utilize the mentioned trace events for pstate and cstate statistics. To achieve more accurate profiling data, the program uses below sequence to insure CPU running/idle time aren't missed: - Before profiling the user space program wakes up all CPUs for once, so can avoid to missing account time for CPU staying in idle state for long time; the program forces to set 'scaling_max_freq' to lowest frequency and then restore 'scaling_max_freq' to highest frequency, this can ensure the frequency to be set to lowest frequency and later after start to run workload the frequency can be easily to be changed to higher frequency; - User space program reads map data and update statistics for every 5s, so this is same with other sample bpf programs for avoiding big overload introduced by bpf program self; - When send signal to terminate program, the signal handler wakes up all CPUs, set lowest frequency and restore highest frequency to 'scaling_max_freq'; this is exactly same with the first step so avoid to missing account CPU pstate and cstate time during last stage. Finally it reports the latest statistics. The program has been tested on Hikey board with octa CA53 CPUs, below is one example for statistics result, the format mainly follows up Jesper Dangaard Brouer suggestion. Jesper reminds to 'get printf to pretty print with thousands separators use %' and setlocale(LC_NUMERIC, "en_US")', tried three different arm64 GCC toolchains (5.4.0 20160609, 6.2.1 20161016, 6.3.0 20170516) but all of them cannot support printf flag character %' on arm64 platform, so go back print number without grouping mode.

While it's rather cumbersome to reduce prologue for cBPF->eBPF migrations wrt spill/fill for r15 which is callee saved register due to bpf_error path in bpf_jit.S that is both used by migrations as well as native eBPF, we can still trivially save 5 bytes in prologue for the former since tail calls can never be used there. cBPF->eBPF migrations also have their own custom prologue in BPF asm that xors A and X reg anyway, so it's fine we skip this here.

While analyzing some of the more complex BPF programs from Cilium, I found that LLVM generally prefers to emit LD_IMM64 instead of MOV32 BPF instructions for loading unsigned 32-bit immediates into a register. Given we cannot change the current/stable LLVM versions that are already out there, lets optimize this case such that the JIT prefers to emit 'mov %eax, imm32' over 'movabsq %rax, imm64' whenever suitable in order to reduce the image size by 4-5 bytes per such load in the typical case, reducing image size on some of the bigger programs by up to 4%. emit_mov_imm32() and emit_mov_imm64() have been added as helpers.

For ages iproute2 has used `struct rtmsg` as the ancillary header for FIB rules and in the process set the protocol value to RTPROT_BOOT. Until ca56209a66 ("net: Allow a rule to track originating protocol") the kernel rules code ignored the protocol value sent from userspace and always returned 0 in notifications. To avoid incompatibility with existing iproute2, send the protocol as a new attribute.

Pull drm fixes from Dave Airlie: "A bunch of fixes for rc3: Exynos: - fixes for using monotonic timestamps - register definitions - removal of unused file ipu-v3L - minor changes - make some register arrays const+static - fix some leaks meson: - fix for vsync atomic: - fix for memory leak EDID parser: - add quirks for some more non-desktop devices - 6-bit panel fix. drm_mm: - fix a bug in the core drm mm hole handling cirrus: - fix lut loading regression Lastly there is a deadlock fix around runtime suspend for secondary GPUs. There was a deadlock between one thread trying to wait for a workqueue job to finish in the runtime suspend path, and the workqueue job it was waiting for in turn waiting for a runtime_get_sync to return. The fixes avoids it by not doing the runtime sync in the workqueue as then we always wait for all those tasks to complete before we runtime suspend" * tag 'drm-fixes-for-v4.16-rc3' of git://people.freedesktop.org/~airlied/linux: (25 commits) drm/tve200: fix kernel-doc documentation comment include drm/edid: quirk Sony PlayStation VR headset as non-desktop drm/edid: quirk Windows Mixed Reality headsets as non-desktop drm/edid: quirk Oculus Rift headsets as non-desktop drm/meson: fix vsync buffer update drm: Handle unexpected holes in color-eviction drm: exynos: Use proper macro definition for HDMI_I2S_PIN_SEL_1 drm/exynos: remove exynos_drm_rotator.h drm/exynos: g2d: Delete an error message for a failed memory allocation in two functions drm/exynos: fix comparison to bitshift when dealing with a mask drm/exynos: g2d: use monotonic timestamps drm/edid: Add 6 bpc quirk for CPT panel in Asus UX303LA gpu: ipu-csi: add 10/12-bit grayscale support to mbus_code_to_bus_cfg gpu: ipu-cpmem: add 16-bit grayscale support to ipu_cpmem_set_image gpu: ipu-v3: prg: fix device node leak in ipu_prg_lookup_by_phandle gpu: ipu-v3: pre: fix device node leak in ipu_pre_lookup_by_phandle drm/amdgpu: Fix deadlock on runtime suspend drm/radeon: Fix deadlock on runtime suspend drm/nouveau: Fix deadlock on runtime suspend drm: Allow determining if current task is output poll worker ...

The packet fanout test generates UDP traffic and reads this with a pair of packet sockets, testing the various fanout algorithms. Avoid non-determinism from reading unrelated background traffic. Fanout decisions are made before unrelated packets can be dropped with a filter, so that is an insufficient strategy [*]. Run the packet socket tests in a network namespace, similar to msg_zerocopy. It it still good practice to install a filter on a packet socket before accepting traffic. Because this is example code, demonstrate that pattern. Open the socket initially bound to no protocol, install a filter, and only then bind to ETH_P_IP. Another source of non-determinism is hash collisions in FANOUT_HASH. The hash function used to select a socket in the fanout group includes the pseudorandom number hashrnd, which is not visible from userspace. To work around this, the test tries to find a pair of UDP source ports that do not collide. It gives up too soon (5 times, every 32 runs) and output is confusing. Increase tries to 20 and revise the error msg. [*] another approach would be to add a third socket to the fanout group and direct all unexpected traffic here. This is possible only when reimplementing methods like RR or HASH alongside this extra catch-all bucket, using the BPF fanout method.
