* ARM: gic: Allow gic arch extensions to provide irqchip flagsColin Cross2011-09-231-0/+1

* ARM: gic: Use cpu pm notifiers to save gic stateColin Cross2011-09-231-0/+187
| | | | | | | | | | | | | | | | | When the cpu is powered down in a low power mode, the gic cpu interface may be reset, and when the cpu cluster is powered down, the gic distributor may also be reset. This patch uses CPU_PM_ENTER and CPU_PM_EXIT notifiers to save and restore the gic cpu interface registers, and the CPU_CLUSTER_PM_ENTER and CPU_CLUSTER_PM_EXIT notifiers to save and restore the gic distributor registers.

| | * | ARM: GIC: avoid routing interrupts to offline CPUsRussell King2011-07-211-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The irq_set_affinity() method can be called with masks which include offline CPUs. This allows offline CPUs to have interrupts routed to them by writing to /proc/irq/*/smp_affinity after hotplug has taken a CPU offline. Fix this by ensuring that we select a target CPU present in both the required affinity and the online CPU mask. Ensure that we return IRQ_SET_MASK_OK (which happens to be 0) on success to ensure generic code copies the new mask into the irq_data structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GIC register accesses today make use of readl()/writel() which prove to be very expensive when used along with mandatory barriers. This mandatory barriers also introduces an un-necessary and expensive l2x0_sync() operation. On Cortex-A9 MP cores, GIC IO accesses from CPU are direct and doesn't go through L2X0 write buffer. A DSB before writel_relaxed() in gic_raise_softirq() is added to be compliant with the Barrier Litmus document - the mailbox scenario.

| * | ARM: gic: use handle_fasteoi_irq for SPIsWill Deacon2011-05-111-16/+16
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the gic uses handle_level_irq for handling SPIs (Shared Peripheral Interrupts), requiring active interrupts to be masked at the distributor level during IRQ handling. On a virtualised system, only the CPU interfaces are virtualised in hardware. Accesses to the distributor must be trapped by the hypervisor, adding latency to the critical interrupt path in Linux. This patch modifies the GIC code to use handle_fasteoi_irq for handling interrupts, which only requires us to signal EOI to the CPU interface when handling is complete. Cascaded IRQ handling is also updated to use the chained IRQ enter/exit functions to honour the flow control of the parent chip. Note that commit 846afbd1 ("GIC: Dont disable INT in ack callback") broke cascading interrupts by forgetting to add IRQ masking. This is no longer an issue because the unmask call is now unnecessary. Tested on Versatile Express and Realview EB (1176 w/ cascaded GICs).

| * ARM: 6777/1: gic: Add hooks for architecture specific extensionsSantosh Shilimkar2011-03-091-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Few architectures combine the GIC with an external interrupt controller. On such systems it may be necessary to update both the GIC registers and the external controller's registers to control IRQ behavior. This can be addressed in couple of possible methods. 1. Export common GIC routines along with 'struct irq_chip gic_chip' and allow architectures to have custom function by override. 2. Provide architecture specific function pointer hooks within GIC library and leave platforms to add the necessary code as part of these hooks. First one might be non-intrusive but have few shortcomings like arch needs to have there own custom gic library. Locks used should be common since it caters to same IRQs etc. Maintenance point of view also it leads to multiple file fixes. The second probably is cleaner and portable. It ensures that all the common GIC infrastructure is not touched and also provides archs to address their specific issue.

| * ARM: irq migration: update GIC migration codeRussell King2011-02-231-13/+12
| | | | | | | | | | | | | | | | | | This cleans up after the conversion to irq_data. Rename the function to match the method, and remove the now useless lookup of the irq descriptor which is never used. Move the bitmask calculation out of the irq_controller_lock region.

| | | | | | | | | | | | | | | | | | The S5P6442 and S5PC100 SoCs have 4 VICs. However, default VIC number is defined 2 in arch/arm/common. So can be happened some problem on it. Basically, it requires for suspend and resume. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
