The type is not really helpful and caused more confusion than clarity - Get rid of the ktime union. The union has become useless as we use the scalar nanoseconds storage unconditionally now. The 32bit timespec alike storage got removed due to the Y2038 limitations some time ago. That leaves the odd union access around for no reason. Clean it up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mpic is either the main interrupt controller or is cascaded behind a GIC.

|/ | | | | | | | | | | | | | | | | When the state names got added a script was used to add the extra argument to the calls.

| * arm64: Add hypervisor safe helper for checking constant capabilitiesSuzuki K Poulose2016-11-161-12/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hypervisor may not have full access to the kernel data structures and hence cannot safely use cpus_have_cap() helper for checking the system capability. Add a safe helper for hypervisors to check a constant system capability, which *doesn't* fall back to checking the bitmap maintained by the kernel. With this, make the cpus_have_cap() only check the bitmask and force constant cap checks to use the new API for quicker checks.

| * irqchip/gic-v3-its: Fix 64bit GIC{R,ITS}_TYPER accessesMarc Zyngier2016-10-171-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GICv3 architecture specification mentions that a 64bit register can be accessed using two 32bit accesses. What it doesn't mention is that this is only guaranteed on a system that implements AArch32, and a pure AArch64 system is allowed not to support this. This causes issues with the GICR_TYPER and GITS_TYPER registers, which are both RO 64bit registers. In order to solve this, this patch switches the TYPER accesses to the gic_read_typer macro already used in other parts of the driver. This makes sure that we always use a 64bit access on 64bit systems, and two 32bit accesses on 32bit system. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

| * irqchip/jcore: Fix lost per-cpu interruptsRich Felker2016-10-141-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The J-Core AIC does not have separate interrupt numbers reserved for cpu-local vs global interrupts. Instead, the driver requesting the irq is expected to know whether its device uses per-cpu interrupts or not. Previously it was assumed that handle_simple_irq could work for both cases, but it intentionally drops interrupts for an irq number that already has a handler running. This resulted in the timer interrupt for one cpu being lost when multiple cpus' timers were set for approximately the same expiration time, leading to stalls. In theory the same could also happen with IPIs. To solve the problem, instead of registering handle_simple_irq as the handler, register a wrapper function which checks whether the irq to be handled was requested as per-cpu or not, and passes it to handle_simple_irq or handle_percpu_irq accordingly.

| * | irqchip: i8259: Allow platforms to override poll functionPaul Burton2016-10-061-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default i8259 polling function (i8259_irq) is nicely generic but is fairly costly. Platforms often provide an alternative means of polling for an i8259 interrupt, and when using the i8259 without device tree have typically just chained its parent interrupt to their own handler function. In order to allow for platform-specific polling functions to be used in cases where the driver is probed via device tree, provide an i8259_set_poll function that accepts a pointer to an alternative poll function that will override the default.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mapping the parent IRQ will use a virq number which may conflict with the hardcoded I8259A_IRQ_BASE..I8259A_IRQ_BASE+15 range that the i8259 driver expects to be free. If this occurs then we'll hit errors when adding the i8259 IRQ domain, since one of its virq numbers will already be in use. Avoid this by adding the i8259 domain before mapping the parent IRQ, such that the i8259 virq numbers become used before the parent interrupt controller gets a chance to use any of them.

Address this by adding a hook for relevant irqchip drivers to call from their compose_msi_msg() callback, to swizzle the physical address with an appropriatly-mapped IOVA for any device attached to one of our DMA ops domains.

If no regressions are found, another large cleanup for the platform will happen as a follow-up, removing dead code and restructuring the platform based on being DT-only. - In mach-imx, similar work is ongoing, but has not come that far. This time, we remove the obsolete board file for the i.MX1 generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only. The remaining board files are for i.MX2 and i.MX3 machines based on old ARM926 or ARM1136 cores that should work with DT in principle. - realview has just been converted from board files to DT, and a lot of code gets removed in the process. This is the last ARM/Keil/Versatile derived platform that was still using board files, the other ones being integrator, versatile and vexpress.

It is connected to the main GIC via a PPI. Amongst other things, this PIC is used for the ARM PMU. This commit adds a simple irqchip driver for this interrupt controller. Since this interrupt controller is not needed early at boot time, we make the driver a proper platform driver rather than use the IRQCHIP_DECLARE() mechanism.
