Hi,
I would like to make a block of kernel code atomic, so that no one (both
xenomai and Linux) can interrupt it.
I use the following :
#define my_local_irq_save(x) ((x) =
ipipe_test_and_stall_pipeline_head() & 1)
#define my_local_irq_restore(x) ipipe_restore_pipeline_head(x)
my_local_irq_save(flags);
< critical section >
my_local_irq_restore(flags);
It works well enough, but rarely an rtdm irq enter into my critical
section.
The rtdm irq is registered in this way : rtdm_irq_request(&priv->irqHnd,
ETH_PORT_IRQ_NUM(priv->port), irqHandler, RTDM_IRQTYPE_EDGE, "rtdm_eth",
priv);
Is it normal ? Are you sure that it cannot happen ?
Thanks,
Paolo
