Subject: question about disable_irq() and free_irq()
Date: Wed, 13 Aug 2025 21:31:41 +0200 [thread overview]
Message-ID: <a943a7ed-7a17-4c22-a617-b327f7f302e9@broadcom.com> (raw)
I have gone through the "Linux generic IRQ handling" page [1] but I
could not find a definitive answer to my question. So hopefully you can
clarify it for me.
I was wondering whether a disable_irq() must be followed by
enable_irq(), leaving the nested disable out of this, or could one call
free_irq() for a disabled irq.
Regards,
Arend
