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) WebThe Simple makefile to compile this driver on Linux laptop is as follows, obj-m += interrupt.o all: make -C /lib/modules/$ (shell uname -r)/build M=$ ( PWD) modules clean: make -C /lib/modules/$ (shell uname -r)/build M=$ (PWD) clean. Compile the driver as, $ make. $ sudo insmod ./interrupt.ko interrupt_name=somename irq=30. Currently we have ...

WebThe irq_domain maintains a radix tree map from hwirq numbers to Linux IRQs. When an hwirq is mapped, an irq_desc is allocated and the hwirq is used as the lookup key for the radix tree. The tree map is a good choice if the hwirq number can be very large since it doesn’t need to allocate a table as large as the largest hwirq number. WebThe struct device_driver structure, which represents one driver capable of handling certain devices on a certain bus. The struct device structure, which represents one device connected to a bus The kernel uses inheritance to create more specialized versions of struct device_driver and struct device for each bus subsystem.
