In order to populate the PCI host bridge msi_domain, use the "msi-parent" attribute to lookup a corresponding irq domain. If found, this is our MSI domain. This gets plugged into the core PCI code. Acked-by:

As MSI-type features are creeping into non-PCI devices, it is starting to make sense to give our struct device some form of support for this, by allowing a pointer to an MSI irq domain to be set/retrieved. Reviewed-by:

It is not uncommon (at least with the ARM stuff) to have a piece of hardware that implements different flavours of "interrupts". A typical example of this is the GICv3 ITS, which implements standard PCI/MSI support, but also some form of "generic MSI". So far, the PCI/MSI domain is registered using the ITS device_node, so that irq_find_host can return it. On the contrary, the raw MSI domain is not registered with an device_node, making it impossible to be looked up by another subsystem (obviously, using the same device_node twice would only result in confusion, as it is not defined which one irq_find_host would return). A solution to this is to "type" domains that may be aliasing, and to be able to lookup an device_node that matches a given type. For this, we introduce irq_find_matching_host() as a superset of irq_find_host: struct irq_domain *irq_find_matching_host(struct device_node *node, enum irq_domain_bus_token bus_token); where bus_token is the "type" we want to match the domain against (so far, only DOMAIN_BUS_ANY is defined). This result in some moderately invasive changes on the PPC side (which is the only user of the .match method). This has otherwise no functionnal change. Reviewed-by: -

Our irq-bcm7120-l2 interrupt controller driver utilizes the same handler function for the different parent interrupts it services: UPG_MAIN, UPG_BSC for instance. The problem is that function reads the IRQSTAT register which can combine interrupt causes for different parent interrupts, such that we can end-up in the following situation: - CPU takes an interrupt - bcm7120_l2_intc_irq_handle() reads IRQSTAT - generic_handle_irq() is invoked - there are still pending interrupts flagged in IRQSTAT from a different parent - handle_bad_irq() is invoked for these since they come from a different irq_desc/irq In order to fix this, make sure that we always mask IRQSTAT with the appropriate bits that correspond go the parent interrupt source this is coming from. To simplify things, associate an unique structure per parent interrupt handler to avoid multiplying the number of lookups.

Make use of the new irq_chip_generic suspend/resume callbacks. This is required because if there are no installed child IRQs for this chip, the irq_chip::irq_{suspend,resume} functions will not be called. However, we still need to save/restore the forwarding mask, to enable the top-level GIC interrupt; otherwise, we lose UART output after S3 resume. In addition to refactoring the callbacks, we have to self-initialize the mask cache, since the genirq core also doesn't initialize this until the first child IRQ is installed.

Brian Norris authored
Some (admittedly odd) irqchips perform functions that are not directly related to any of their child IRQ lines, and therefore need to perform some tasks during suspend/resume regardless of whether there are any "installed" interrupts for the irqchip. However, the current generic-chip framework does not call the chip's irq_{suspend,resume} when there are no interrupts installed (this makes sense, because there are no irq_data objects for such a call to be made). More specifically, irq-bcm7120-l2 configures both a forwarding mask (which affects other top-level GIC IRQs) and a second-level interrupt mask (for managing its own child interrupts). The former must be saved/restored on suspend/resume, even when there's nothing to do for the latter. This patch adds a new set of suspend/resume hooks to irq_chip_generic, to help represent *chip* suspend/resume, rather than IRQ suspend/resume. These callbacks will always be called for an IRQ chip (regardless of the installed interrupts) and are based on the per-chip irq_chip_generic struct, rather than the per-IRQ irq_data struct.

The GIC controller doesn't provides any facility to configure the wakeup sources. For the same reason, GIC chip implementation can't provide irq_set_wake functionality, but that results in the irqchip core preventing the systems from entering sleep states like "suspend to RAM". The GICv1/v2 controllers support wakeup events. They signal these wakeup events even when CPU interface is disabled which means the wakeup outputs are always enabled with the required logic in always-on domain. An implementation can powerdown the GIC completely, but then the wake-up must be relayed to some control logic within the power controller that acts as wake-up interrupt controller. Setting the IRQCHIP_SKIP_SET_WAKE flags will ensure that the interrupts from GIC can work as wakeup interrupts and resume from suspend-to-{idle, ram}. The wakeup interrupt sources need to use enable_irq_wake() and the irqchip core will then set the IRQD_WAKEUP_STATE flag. Also it's always safer to mask all the non wakeup interrupts are masked at the chip level when suspending. The irqchip infrastructure can handle masking of those interrupts at the chip level. The chip implementation just have to indicate that with IRQCHIP_MASK_ON_SUSPEND. This patch enables IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND so that the irqchip core allows and handles the power managemant wake up modes. Signed-off-by:

Toshi explains: "No, the default values need to be set to the fallback types, i.e. minimal supported mode. For WC and WT, UC is the fallback type. When PAT is disabled, pat_init() does update the tables below to enable WT per the default BIOS setup. However, when PAT is enabled, but CPU has PAT -errata, WT falls back to UC per the default values." Revert: ca1fec58 'x86/mm/pat: Adjust default caching mode translation tables' Requested-by:
