2019-02-21fanotify: Make waits for fanotify events only killableJan Kara
Making waits for response to fanotify permission events interruptible can result in EINTR returns from open(2) or other syscalls when there's e.g. AV software that's monitoring the file. Orion reports that e.g. bash is complaining like: bash: /etc/bash_completion.d/itweb-settings.bash: Interrupted system call So for now convert the wait from interruptible to only killable one. That is mostly invisible to userspace. Sadly this breaks hibernation with fanotify permission events pending again but we have to put more thought into how to fix this without regressing userspace visible behavior.

2019-02-21irqchip/gicv3-its: Use NUMA aware memory allocation for ITS tablesShanker Donthineni
The NUMA node information is visible to ITS driver but not being used other than handling hardware errata. ITS/GICR hardware accesses to the local NUMA node is usually quicker than the remote NUMA node. How slow the remote NUMA accesses are depends on the implementation details. This patch allocates memory for ITS management tables and command queue from the corresponding NUMA node using the appropriate NUMA aware functions. This change improves the performance of the ITS tables read latency on systems where it has more than one ITS block, and with the slower inter node accesses. Apache Web server benchmarking using ab tool on a HiSilicon D06 board with multiple numa mem nodes shows Time per request and Transfer rate improvements of ~3.6% with this patch.

2019-02-21irqdomain: Allow the default irq domain to be retrievedMarc Zyngier
The default irq domain allows legacy code to create irqdomain mappings without having to track the domain it is allocating from. Setting the default domain is a one shot, fire and forget operation, and no effort was made to be able to retrieve this information at a later point in time. Newer irqdomain APIs (the hierarchical stuff) relies on both the irqchip code to track the irqdomain it is allocating from, as well as some form of firmware abstraction to easily identify which piece of HW maps to which irq domain (DT, ACPI). For systems without such firmware (or legacy platform that are getting dragged into the 21st century), things are a bit harder. For these cases (and these cases only!), let's provide a way to retrieve the default domain, allowing the use of the v2 API without having to resort to platform-specific hacks.

2019-02-21irqchip/sifive-plic: Implement irq_set_affinity() for SMP hostAnup Patel
Currently on SMP host, all CPUs take external interrupts routed via PLIC. All CPUs will try to claim a given external interrupt but only one of them will succeed while other CPUs would simply resume whatever they were doing before. This means if we have N CPUs then for every external interrupt N-1 CPUs will always fail to claim it and waste their CPU time. Instead of above, external interrupts should be taken by only one CPU and we should have provision to explicitly specify IRQ affinity from kernel-space or user-space. This patch provides irq_set_affinity() implementation for PLIC driver. It also updates irq_enable() such that PLIC interrupts are only enabled for one of CPUs specified in IRQ affinity mask. With this patch in-place, we can change IRQ affinity at any-time from user-space using procfs. Example: / # cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 8: 44 0 0 0 SiFive PLIC 8 virtio0 10: 48 0 0 0 SiFive PLIC 10 ttyS0 IPI0: 55 663 58 363 Rescheduling interrupts IPI1: 0 1 3 16 Function call interrupts / # / # / # echo 4 > /proc/irq/10/smp_affinity / # / # cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 8: 45 0 0 0 SiFive PLIC 8 virtio0 10: 160 0 17 0 SiFive PLIC 10 ttyS0 IPI0: 68 693 77 410 Rescheduling interrupts IPI1: 0 2 3 16 Function call interrupts Signed-off-by: Anup Patel <anup@brainfault.org> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2019-02-21irqchip/sifive-plic: Differentiate between PLIC handler and contextAnup Patel
We explicitly differentiate between PLIC handler and context because PLIC context is for given mode of HART whereas PLIC handler is per-CPU software construct meant for handling interrupts from a particular PLIC context. To achieve this differentiation, we rename "nr_handlers" to "nr_contexts" and "nr_mapped" to "nr_handlers" in plic_init().

2019-02-21irqchip/sifive-plic: Add warning in plic_init() if handler already presentAnup Patel
We have two enteries (one for M-mode and another for S-mode) in the interrupts-extended DT property of PLIC DT node for each HART. It is expected that firmware/bootloader will set M-mode HWIRQ line of each HART to 0xffffffff (i.e. -1) in interrupts-extended DT property because Linux runs in S-mode only. If firmware/bootloader is buggy then it will not correctly update interrupts-extended DT property which might result in a plic_handler configured twice. This patch adds a warning in plic_init() if a plic_handler is already marked present. This warning provides us a hint about incorrectly updated interrupts-extended DT property.
