Irq_type_level_low
WebWhenever an interrupt triggers, the low-level architecture code calls into the generic interrupt code by calling desc->handle_irq (). This 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: WebThis leads to a mix of flow logic and low-level hardware logic, and it also leads to unnecessary code duplication: for example in i386, there is an ioapic_level_irq and an …

In the Windows Driver Model, a thread running at a low IRQL can be interrupted to run code at a higher IRQL. The number of IRQL's and their specific values are processor-dependent. Processes running at a higher IRQL will pre-empt a ...
