i.MX28: GPIO interrupt on both rising and falling edges

WebOct 6, 2024 · Each processor, or shared memory device (SMD), is called an “edge”, and has a unique identifier smd-edge, as well as a remote identifier remote-pid used by other processors to refer to it. They also use interrupts and mailbox doorbells to signal events such as opening a SMD channel or receiving a message. WebThis high-level IRQ handling function only uses desc->irq_data.chip primitives referenced by the assigned chip descriptor structure. High-level Driver API The high-level Driver API consists of following functions: request_irq () free_irq () disable_irq () enable_irq () disable_irq_nosync () (SMP only) synchronize_irq () (SMP only) sailboat charter miami

WebI am hooking the interrupt pin from my peripheral directly to the IRQ_F2P port on the Zynq PS. The issue is that even though I have set the sensitivity of my interrupt to be "EDGE_RISING" in my peripheral, the PS seems to want to treat the interrupt sensitivity as though it is LEVEL_HIGH. WebThe approach here is to use PDC interrupt at all times (while keeping the GPIO irq disabled). The PDC interrupt handler invokes the action handler of the GPIO IRQ instead. This allows us to avoid interrupt hand-offs while entering idle states and keeps things very simple. The wake_irq_gpio_handler() is the crux of this new revision. thick menu paper
