Hello Holger,
makes no sense because the isr register is cleared by the IRQ handler
before the tasklets get running. sorry,
Right.
What about this:
in irq handler:
saved_isr |= readreg(isr) & IRQ_BIT;
in tasklet handler:
do {
... do it ...
} while ((saved_isr) || (readreg(isr) & IRQ_BIT));
:) (good things always show up multiple times;)
It maybe needs some locking.
Yes, it does. A spinlock should be used to protect the saved_isr variable.
maybe.
