I mean interrupts managed by the same irq_handler() Gabriele
Da: Jadav, Brijesh R [mailto:[EMAIL PROTECTED] Inviato: mercoledì 15 ottobre 2008 16.05 A: Gabriele Filosofi; [email protected] Oggetto: RE: How to prevent other interrupts to occour during interrupt handling Hi, I think you can use enable_irq/disable_irq to enable/disable a particular interrupt or local_irq_save and local_irq_restore to prevent all interrupt to occur. Can you tell me what you mean by other interrupts of the same type? Thanks, Brijesh Jadav ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gabriele Filosofi Sent: Wednesday, October 15, 2008 6:30 PM To: [email protected] Subject: How to prevent other interrupts to occour during interrupt handling Hi, after having enabled an interrupt source with request_irq(gpio_to_irq(37), &irq_handler, IRQF_TRIGGER_FALLING, "myirq", NULL); how to prevent other interrupts (of the same type) to occour during irq_handler() processing? I would like to disable the interrupt only for the irq_handler() execution time. Thanks and regards (sorry for this questioni if too simple!) Gabriele
