How long does it take from a call to rtl_hard_enable_irq() before the system
is ready for the next interrupt?
The reason I ask: I have an interrupt acquisition system that has external
hardware that vetoes further interrupts until I clear it from the rtl code.
It looks something like this:
rtl_hard_enable_irq(theirq);
clear_irq_veto();
At high instantaneous interrupt rates, hundreds of kHz, the acquisition
system dies. I was able to keep it alive in the face of such rates but
adding an hardware delay of 2-3 microsecs after clear_irq_veto() removes the
hardware veto.
Thanks! Ken
