genirq: Move non-irqdomain handle_domain_irq() handling into ARM's handle_IRQ()

2021-06-10T12:09:19+00:00

Despite the name, handle_domain_irq() deals with non-irqdomain handling for the sake of a handful of legacy ARM platforms. Move such handling into ARM's handle_IRQ(), allowing for better code generation for everyone else. This allows us get rid of some complexity, and to rearrange the guards on the various helpers in a more logical way. Signed-off-by: Marc Zyngier

genirq: Add generic_handle_domain_irq() helper

2021-06-10T12:09:19+00:00

Provide generic_handle_domain_irq() as a pendent to handle_domain_irq() for non-root interrupt controllers Signed-off-by: Marc Zyngier

irqdesc: Fix __handle_domain_irq() comment

2021-06-10T12:09:18+00:00

It appears that the comment about a NULL domain meaning anything has always been wrong. Fix it. Signed-off-by: Marc Zyngier

genirq: Use irq_resolve_mapping() to implement __handle_domain_irq() and co

2021-06-10T12:09:18+00:00

In order to start reaping the benefits of irq_resolve_mapping(), start using it in __handle_domain_irq() and handle_domain_nmi(). This involves splitting generic_handle_irq() to be able to directly provide the irq_desc. Signed-off-by: Marc Zyngier

irq: Fix typos in comments

genirq: Provide kstat_irqdesc_cpu()

2020-12-15T15:19:31+00:00

Most users of kstat_irqs_cpu() have the irq descriptor already. No point in calling into the core code and looking it up once more. Use it in per_cpu_count_show() to start with. Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/r/20201210194043.362094758@linutronix.de

genirq: Move irq_set_lockdep_class() to core

2020-12-15T15:19:30+00:00

irq_set_lockdep_class() is used from modules and requires irq_to_desc() to be exported. Move it into the core code which lifts another requirement for the export. Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/r/20201210194042.860029489@linutronix.de

genirq: Move status flag checks to core

2020-12-15T15:19:30+00:00

These checks are used by modules and prevent the removal of the export of irq_to_desc(). Move the accessor into the core. Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/r/20201210194042.703779349@linutronix.de

genirq: Move irq_has_action() into core code

2020-12-15T15:19:30+00:00

This function uses irq_to_desc() and is going to be used by modules to replace the open coded irq_to_desc() (ab)usage. The final goal is to remove the export of irq_to_desc() so driver cannot fiddle with it anymore. Move it into the core code and fixup the usage sites to include the proper header.

genirq: Remove preflow handler support

2020-07-04T08:02:06+00:00

That was put in place for sparc64, and blackfin also used it for some time; sparc64 no longer uses those, and blackfin is dead. As there are no more users, remove preflow handlers.
