Subject: MIssed interrupts
Date: Thu, 7 Feb 2008 10:42:18 +0530 [thread overview]
Message-ID: <7783925d0802062112r4637c674qf2d1dd356cc0923e@mail.gmail.com> (raw)
Hi,
If a particual IRQ line has been disabled (disable_irq()), what
happens if the device on that IRQ line generates interrupt? Does it
result in missed interrupt?
And in case of Uniprocessor machine, what happens if interrupts are
generated while spinlock_irq_save() etc?
TIA,
Rick
