irq: remove handle_domain_{irq,nmi}()

2021-10-26T09:13:31+00:00

Now that entry code handles IRQ entry (including setting the IRQ regs) before calling irqchip code, irqchip code can safely call generic_handle_domain_irq(), and there's no functional reason for it to call handle_domain_irq(). Let's cement this split of responsibility and remove handle_domain_irq() entirely, updating irqchip drivers to call generic_handle_domain_irq(). For consistency, handle_domain_nmi() is similarly removed and replaced with a generic_handle_domain_nmi() function which also does not perform any entry logic. Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire when they were called in an inappropriate context. So that we can identify similar issues going forward, similar WARN_ON_ONCE() logic is added to the generic_handle_*() functions, and comments are updated for clarity and consistency.

Correctly escape the * not to be used as emphasis. Also take this opportunity to clarify the fate of the rest of the legacy APIs. Reported-by: Stephen Rothwell Signed-off-by: Marc Zyngier Link: https://lore.kernel.org/r/20210903085343.923036-1-maz@kernel.org

irqdomain: Introduce irq_domain_create_simple() API

2021-03-26T13:56:18+00:00

Linus Walleij pointed out that ird_domain_add_simple() gained additional functionality and can't be anymore replaced with a simple conditional. In preparation to upgrade GPIO library to use fwnode, introduce irq_domain_create_simple() API which is functional equivalent to the existing irq_domain_add_simple(), but takes a pointer to the struct fwnode_handle as a parameter. While at it, amend documentation to mention irq_domain_create_*() functions where it makes sense. Signed-off-by: Andy Shevchenko Acked-by: Marc Zyngier Signed-off-by: Bartosz Golaszewski

irqdomain: Introduce irq_domain_create_legacy() API

Introduce irq_domain_create_legacy() API which is functional equivalent to the existing irq_domain_add_legacy(), but takes a pointer to the struct fwnode_handle as a parameter.

docs: add IRQ documentation at the core-api book

2020-05-15T18:00:56+00:00

There are 4 IRQ documentation files under Documentation/*.txt. Move them into a new directory (core-api/irq) and add a new index file for it. While here, use a title markup for the Debugging section of the irq-domain.rst file.
