Hi, all,
I meet a problem about mpsleep in my driver code.
First I up interrupt priority to mask network device
interrupt.
Second I call mpsleep
Third I do not know when I wake up from mpsleep,
the interrupt priority is the same before I up
interrupt priority or the same before I call mpsleep.
That mean can mpsleep down the interrupt priority
automatically?
I read the advance topics about device driver, it
explain the mpsleep function meaning.
I do not know well the interrupt or uninterrupt exactly
meaning. "interrupt" mean hardware interrupt, or
software interrupt, or software signal?
If someone knows, please help me.
Thanks in advance!
