2015-08-20irqchip/crossbar: Restore set_wake functionalityGrygorii Strashko1-2/+2
The TI crossbar irqchip doesn't provides any facility to configure the wakeup sources, but the conversion to hierarchical irqdomains set the irq_set_wake callback to irq_chip_set_wake_parent. The parent chip (OMAP wakeupgen) has no irq_set_wake function either so the call will fail with -ENOSYS. As a result the irq_set_wake() call in the resume path will trigger an 'Unbalanced wake disable' warning. Before the conversion the GIC irqchip was the top level irqchip and correctly flagged with IRQCHIP_SKIP_SET_WAKE. Restore the correct behaviour by removing the irq_set_type callback from the crossbar irqchip and set the IRQCHIP_SKIP_SET_WAKE flag which lets the irq_set_irq_wake() call from the driver succeed.

2015-08-20irqchip/crossbar: Restore the mask on suspend behaviourGrygorii Strashko1-0/+1
The ARM GIC requires that all interrupts which are not used as a wakeup source have to be masked during suspend. The conversion of the crossbar irqchip to hierarchical irq domains failed to mark the crossbar irqchip with the IRQCHIP_MASK_ON_SUSPEND flag and therefor broke the suspend requirement of the GIC. Before the conversion the flags were visible because the GIC was the top level irqchip. After the conversion the crossbar irqchip is the top level irq chip whose flags are evaluated in suspend_device_irq(). As the flag is not set the masking of the non-wakeup irqs is not invoked which breaks suspend. Add the IRQCHIP_MASK_ON_SUSPEND flag to the crossbar irqchip, so the GIC interrupts get masked properly.

2015-08-20irqchip/crossbar: Restore the irq_set_type() mechanismGrygorii Strashko1-0/+1
The conversion of the crossbar irqchip to hierarchical irq domains failed to provide a mechanism to properly set the trigger type of an interrupt. The crossbar irq chip itself has no mechanism and therefor no irq_set_type() callback. The code before the conversion relayed the trigger configuration directly to the underlying GIC. Restore the correct behaviour by setting the crossbar irq_set_type callback to irq_chip_set_type_parent(). This propagates the set_trigger() call to the underlying GIC irqchip.

2015-08-03MIPS: SMP: Don't increment irq_count multiple times for call function IPIsAlex Smith1-1/+1
The majority of SMP platforms handle their IPIs through do_IRQ() which calls irq_{enter/exit}(). When a call function IPI is received, smp_call_function_interrupt() is called which also calls irq_{enter,exit}(), meaning irq_count is raised twice. When tick broadcasting is used (which is implemented via a call function IPI), this incorrectly causes all CPU idle time on the core receiving broadcast ticks to be accounted as time spent servicing IRQs, as account_process_tick() will account as such if irq_count is greater than 1. This results in 100% CPU usage being reported on a core which receives its ticks via broadcast. This patch removes the SMP smp_call_function_interrupt() wrapper which calls irq_{enter,exit}(). Platforms which handle their IPIs through do_IRQ() now call generic_smp_call_function_interrupt() directly to avoid incrementing irq_count a second time. Platforms which don't (loongson, sgi-ip27, sibyte) call generic_smp_call_function_interrupt() wrapped in irq_{enter,exit}().

2015-07-17irqchip/gicv3-its: Fix mapping of LPIs to collectionsMarc Zyngier1-36/+75
The GICv3 ITS architecture allows a given [DevID, EventID] pair to be translated to a [LPI, Collection] pair, where DevID is the device writing the MSI, EventID is the payload being written, LPI is the actual interrupt number, and Collection is roughly equivalent to a target CPU. Each LPI can be mapped to a separate collection, but the ITS driver insists on maintaining the collection on a device basis, instead of doing it on a per interrupt basis. This is obviously flawed, and this patch fixes it by adding a per interrupt index that indicates which collection number is in use.

2015-07-10MIPS: Malta: Make GIC FDC IRQ workaround Malta specificJames Hogan1-10/+0
Wider testing reveals that the Fast Debug Channel (FDC) interrupt is routed through the GIC just fine on Pistachio SoC, even though it contains interAptiv cores. Clearly the FDC interrupt routing problems previously observed on interAptiv and proAptiv cores are specific to the Malta FPGA bitstreams. Move the workaround for interAptiv and proAptiv out of gic_get_c0_fdc_int() in the GIC irqchip driver into Malta's get_c0_fdc_int() platform callback, to allow the Pistachio SoC to use the FDC interrupt.

For those parts of the arm64 ACPI code that need to check GICC subtables in the MADT, use the new BAD_MADT_GICC_ENTRY macro instead of the previous BAD_MADT_ENTRY. The new macro takes into account differences in the size of the GICC subtable that the old macro did not; this caused failures even though the subtable entries are valid.

2015-07-02irqchip: Move IRQCHIP_DECLARE macro to include/linux/irqchip.hJoel Porquet1-18/+1
At the moment the IRQCHIP_DECLARE macro is only declared locally in drivers/irqchip/irqchip.h. It prevents from using it directly in arch/* directories whenever irqchip drivers only exist there, which happens in a few cases (e.g. arc, arm, microblaze and mips). This patch makes the macro to be globally defined, i.e. in include/linux/irqchip.h, and thus usable for arch-specific declarations of irqchip drivers. In this way, it is very similar to what clocksource does (ie CLOCKSOURCE_OF_DECLARE is defined in include/linux/clocksource.h). For now, this patch only moves the declaration of the macro IRQCHIP_DECLARE to the global header 'include/linux/irqchip.h' and make 'drivers/irqchip/irqchip.h' include 'include/linux/irqchip.h'. Later, other patches will get rid of 'drivers/irqchip/irqchip.h' and modify all the impacted irqchip drivers.

Details: - fix handling of clock in chipco SSB driver. - fix two MIPS-specific #if conditions to correctly work for GCC 5.1. - fix damage to R6 pgtable bits done by XPA support. - fix possible crash due to unloading modules that contain statically defined platform devices. - fix disabling of the MSA ASE on context switch to also work correctly when a new thread/process has the CPU for the very first time. This is part of linux-next and has been beaten to death on Imagination's test farm. While things are not looking too grim this pull request also means the rate of fixes for 4.1 remains nearly constant so I'd not be unhappy if you'd delay the release" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MPI: MIPS: Fix compilation error with GCC 5.1 IRQCHIP: mips-gic: Don't nest calls to do_IRQ() MIPS: MSA: bugfix - disable MSA correctly for new threads/processes. MIPS: Loongson: Do not register 8250 platform device from module. MIPS: Cobalt: Do not build MTD platform device registration code as module.

2015-06-13IRQCHIP: mips-gic: Don't nest calls to do_IRQ()Rabin Vincent1-7/+14
The GIC chained handlers use do_IRQ() to call the subhandlers. This means that irq_enter() calls get nested, which leads to preempt count looking like we're in nested interrupts, which in turn leads to all system time being accounted as IRQ time in account_system_time(). Fix it by using generic_handle_irq(). Since these same functions are used in some systems (if cpu_has_veic) from a low-level vectored interrupt handler which does not go throught do_IRQ(), we need to do it conditionally.

2015-06-05irqchip: gic: Simplify gic_configure_irq by using IRQCHIP_SET_TYPE_MASKEDSudeep Holla4-17/+3
GIC requires to disable the interrupt before changing the trigger type. irqchip core provides IRQCHIP_SET_TYPE_MASKED flag and ensures that the interrupt is masked before calling chip.irq_set_type() if the irqchip sets the flag. This patch adds IRQCHIP_SET_TYPE_MASKED to GIC irqchip so that the core can manage disabling the interrupt while changing the trigger type.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull initial ACPI support for arm64 from Will Deacon: "This series introduces preliminary ACPI 5.1 support to the arm64 kernel using the "hardware reduced" profile. We don't support any peripherals yet, so it's fairly limited in scope: - MEMORY init (UEFI) - ACPI discovery (RSDP via UEFI) - CPU init (FADT) - GIC init (MADT) - SMP boot (MADT + PSCI) - ACPI Kconfig options (dependent on EXPERT) ACPI for arm64 has been in development for a while now and hardware has been available that can boot with either FDT or ACPI tables. This has been made possible by both changes to the ACPI spec to cater for ARM-based machines (known as "hardware-reduced" in ACPI parlance) but also a Linaro-driven effort to get this supported on top of the Linux kernel. This pull request is the result of that work. These changes allow us to initialise the CPUs, interrupt controller, and timers via ACPI tables, with memory information and cmdline coming from EFI. We don't support a hybrid ACPI/FDT scheme. Of course, there is still plenty of work to do (a serial console would be nice!) but I expect that to happen on a per-driver basis after this core series has been merged. Anyway, the diff stat here is fairly horrible, but splitting this up and merging it via all the different subsystems would have been extremely painful. Instead, we've got all the relevant Acks in place and I've not seen anything other than trivial (Kconfig) conflicts in -next (for completeness, I've included my resolution below). Nearly half of the insertions fall under Documentation/. So, we'll see how this goes.
