There are several similar irq handlers with confusing function names and it's not friendly to call update_irq_handler() to update a proper handler after request_irq(). With this commit, a single generic irq handler is being used, in which, no lock need to be acquired because our design could guarantee there is no concurrent irq handling and irq handler request/free. A flags field is added to irq_desc struct to select the proper processing flow for an irq. Irqflags is defined as follows: IRQF_NONE (0U) IRQF_LEVEL (1U << 1U) /* 1: level trigger; 0: edge trigger */ IRQF_PT (1U << 2U) /* 1: for passthrough dev */ Because we have only one irq handler, update_irq_handler() should be replace by set_irq_trigger_mode(), whichs set trigger mode flag of a certian irq. Accordingly, the code where called update_irq_handler() need to be updated. Signed-off-by: Yan, Like <like.yan@intel.com> Acked-by: Anthony Xu <anthony.xu@intel.com> |
