2019-12-14drm/gma500: Pass GPIO for Intel MID using descriptorsLinus Walleij
The GMA500 driver is using the legacy GPIO API to fetch three optional display control GPIO lines from the SFI description used by the Medfield platform. Switch this over to use GPIO descriptors and delete the custom platform data. We create three new static locals in the tc35876x bridge code but it is hardly any worse than the I2C client static local already there: I tried first to move it to the DRM driver state container but there are workarounds for probe order in the code so I just stayed off it, as the result is unpredictable. People wanting to do a more throrugh and proper cleanup of the GMA500 driver can work on top of this, I can't solve much more since I don't have access to the hardware, I can only attempt to tidy up my GPIO corner.

2019-12-11s390: remove last diag 0x44 callerHeiko Carstens
diag 0x44 is a voluntary undirected yield of a virtual CPU. This has caused a lot of performance issues in the past. There is only one caller left, and that one is only executed if diag 0x9c (directed yield) is not present. Given that all hypervisors implement diag 0x9c anyway, remove the last diag 0x44 to avoid that more callers will be added. Worst case that could happen now, if diag 0x9c is not present, is that a virtual CPU would loop a bit instead of giving its time slice up. diag 0x44 statistics in debugfs are kept and will always be zero, so that user space can tell that there are no calls.

2019-12-11s390/cpum_sf: Avoid SBD overflow condition in irq handlerThomas Richter
The s390 CPU Measurement sampling facility has an overflow condition which fires when all entries in a SBD are used. The measurement alert interrupt is triggered and reads out all samples in this SDB. It then tests the successor SDB, if this SBD is not full, the interrupt handler does not read any samples at all from this SDB The design waits for the hardware to fill this SBD and then trigger another meassurement alert interrupt. This scheme works nicely until an perf_event_overflow() function call discards the sample due to a too high sampling rate. The interrupt handler has logic to read out a partially filled SDB when the perf event overflow condition in linux common code is met. This causes the CPUM sampling measurement hardware and the PMU device driver to operate on the same SBD's trailer entry. This should not happen. This can be seen here using this trace: cpumsf_pmu_add: tear:0xb5286000 hw_perf_event_update: sdbt 0xb5286000 full 1 over 0 flush_all:0 hw_perf_event_update: sdbt 0xb5286008 full 0 over 0 flush_all:0 above shows 1. interrupt hw_perf_event_update: sdbt 0xb5286008 full 1 over 0 flush_all:0 hw_perf_event_update: sdbt 0xb5286008 full 0 over 0 flush_all:0 above shows 2. interrupt ... this goes on fine until... hw_perf_event_update: sdbt 0xb5286068 full 1 over 0 flush_all:0 perf_push_sample1: overflow one or more samples read from the IRQ handler are rejected by perf_event_overflow() and the IRQ handler advances to the next SDB and modifies the trailer entry of a partially filled SDB. hw_perf_event_update: sdbt 0xb5286070 full 0 over 0 flush_all:1 timestamp: 14:32:52.519953 Next time the IRQ handler is called for this SDB the trailer entry shows an overflow count of 19 missed entries. hw_perf_event_update: sdbt 0xb5286070 full 1 over 19 flush_all:1 timestamp: 14:32:52.970058 Remove access to a follow on SDB when event overflow happened.

2019-12-11s390/cpum_sf: Adjust sampling interval to avoid hitting sample limitsThomas Richter
Function perf_event_ever_overflow() and perf_event_account_interrupt() are called every time samples are processed by the interrupt handler. However function perf_event_account_interrupt() has checks to avoid being flooded with interrupts (more then 1000 samples are received per task_tick). Samples are then dropped and a PERF_RECORD_THROTTLED is added to the perf data. The perf subsystem limit calculation is: maximum sample frequency := 100000 --> 1 samples per 10 us task_tick = 10ms = 10000us --> 1000 samples per task_tick The work flow is measurement_alert() uses SDBT head and each SBDT points to 511 SDB pages, each with 126 sample entries. After processing 8 SBDs and for each valid sample calling: perf_event_overflow() perf_event_account_interrupts() there is a considerable amount of samples being dropped, especially when the sample frequency is very high and near the 100000 limit. To avoid the high amount of samples being dropped near the end of a task_tick time frame, increment the sampling interval in case of dropped events. The CPU Measurement sampling facility on the s390 supports only intervals, specifiing how many CPU cycles have to be executed before a sample is generated. Increase the interval when the samples being generated hit the task_tick limit. Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>

Commit fd7d58f0dbc3 ("ARM: multi_v7_defconfig: renormalize based on recent additions") removed explicit enable line for CONFIG_DEBUG_FS, because that feature has been selected by other enabled options: CONFIG_TRACING, which were enabled by CONFIG_PERF_EVENTS. In meantime, commit 0e4a459f56c3 ("tracing: Remove unnecessary DEBUG_FS dependency") removed the dependency between CONFIG_DEBUG_FS and CONFIG_TRACING, so CONFIG_DEBUG_FS is no longer enabled in default builds. Enable it again explicitly, as debugfs support is essential for various automated testing tools.

2019-12-06arm64: ftrace: fix ifdefferyMark Rutland
When I tweaked the ftrace entry assembly in commit: 3b23e4991fb66f6d ("arm64: implement ftrace with regs") ... my ifdeffery tweaks left ftrace_graph_caller undefined for CONFIG_DYNAMIC_FTRACE && CONFIG_FUNCTION_GRAPH_TRACER when ftrace is based on mcount. The kbuild test robot reported that this issue is detected at link time: | arch/arm64/kernel/entry-ftrace.o: In function `skip_ftrace_call': | arch/arm64/kernel/entry-ftrace.S:238: undefined reference to `ftrace_graph_caller' | arch/arm64/kernel/entry-ftrace.S:238:(.text+0x3c): relocation truncated to fit: R_AARCH64_CONDBR19 against undefined symbol | `ftrace_graph_caller' | arch/arm64/kernel/entry-ftrace.S:243: undefined reference to `ftrace_graph_caller' | arch/arm64/kernel/entry-ftrace.S:243:(.text+0x54): relocation truncated to fit: R_AARCH64_CONDBR19 against undefined symbol | `ftrace_graph_caller' This patch fixes the ifdeffery so that the mcount version of ftrace_graph_caller doesn't depend on CONFIG_DYNAMIC_FTRACE. At the same time, a redundant #else is removed from the ifdeffery for the patchable-function-entry version of ftrace_graph_caller.

2019-12-06arm64: KVM: Invoke compute_layout() before alternatives are appliedSebastian Andrzej Siewior
compute_layout() is invoked as part of an alternative fixup under stop_machine(). This function invokes get_random_long() which acquires a sleeping lock on -RT which can not be acquired in this context. Rename compute_layout() to kvm_compute_layout() and invoke it before stop_machine() applies the alternatives. Add a __init prefix to kvm_compute_layout() because the caller has it, too (and so the code can be discarded after boot).

2019-12-06arm64: Validate tagged addresses in access_ok() called from kernel threadsCatalin Marinas
__range_ok(), invoked from access_ok(), clears the tag of the user address only if CONFIG_ARM64_TAGGED_ADDR_ABI is enabled and the thread opted in to the relaxed ABI. The latter sets the TIF_TAGGED_ADDR thread flag. In the case of asynchronous I/O (e.g. io_submit()), the access_ok() may be called from a kernel thread. Since kernel threads don't have TIF_TAGGED_ADDR set, access_ok() will fail for valid tagged user addresses. Example from the ffs_user_copy_worker() thread: use_mm(io_data->mm); ret = ffs_copy_to_iter(io_data->buf, ret, &io_data->data); unuse_mm(io_data->mm); Relax the __range_ok() check to always untag the user address if called in the context of a kernel thread. The user pointers would have already been checked via aio_setup_rw() -> import_{single_range,iovec}() at the time of the asynchronous I/O request.

2019-12-06ARM: 8943/1: Fix topology setup in case of CPU hotplug for CONFIG_SCHED_MCDietmar Eggemann
Commit ca74b316df96 ("arm: Use common cpu_topology structure and functions.") changed cpu_coregroup_mask() from the ARM32 specific implementation in arch/arm/include/asm/topology.h to the one shared with ARM64 and RISCV in drivers/base/arch_topology.c. Currently on ARM32 (TC2 w/ CONFIG_SCHED_MC) the task scheduler setup code (w/ CONFIG_SCHED_DEBUG) shows this during CPU hotplug: ERROR: groups don't span domain->span It happens to CPUs of the cluster of the CPU which gets hot-plugged out on scheduler domain MC. Turns out that the shared cpu_coregroup_mask() requires that the hot-plugged CPU is removed from the core_sibling mask via remove_cpu_topology(). Otherwise the 'is core_sibling subset of cpumask_of_node()' doesn't work. In this case the task scheduler has to deal with cpumask_of_node instead of core_sibling which is wrong on scheduler domain MC. e.g. CPU3 hot-plugged out on TC2 [cluster0: 0,3-4 cluster1: 1-2]: cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,3-4 ^ should be: cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,4 Add remove_cpu_topology() to __cpu_disable() to remove the CPU from the topology masks in case of a CPU hotplug out operation. At the same time tweak store_cpu_topology() slightly so it will call update_siblings_masks() in case of CPU hotplug in operation via secondary_start_kernel()->smp_store_cpu_info(). This aligns the ARM32 implementation with the ARM64 one. Guarding remove_cpu_topology() with CONFIG_GENERIC_ARCH_TOPOLOGY is necessary since some Arm32 defconfigs (aspeed_g5_defconfig, milbeaut_m10v_defconfig, spear13xx_defconfig) specify an explicit # CONFIG_ARM_CPU_TOPOLOGY is not set w/ ./arch/arm/Kconfig: select GENERIC_ARCH_TOPOLOGY if ARM_CPU_TOPOLOGY Fixes: ca74b316df96 ("arm: Use common cpu_topology structure and functions") Reviewed-by: Sudeep Holla <sudeep.holla@arm.com> Reviewed-by: Lukasz Luba <lukasz.luba@arm.com> Tested-by: Lukasz Luba <lukasz.luba@arm.com> Tested-by: Ondrej Jirman <megous@megous.com> Signed-off-by: Dietmar Eggemann <dietmar.eggemann@arm.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
