I realize that the Windows model assumes your going to either complete I/O quickly or mark the requests as pending, but is there simple way to issue a sleep()?
When my device is installed I read the configuration of the device. However, part of the process is for me to first enable it, then hardware takes x amount of time to populate the configuration data, then I read that configuration data.
Is there a simple way for me to stall execution to allow hardware to fetch the configuration data?
Look at KeDelayExecutionThread or KeStallExecutionProcessor (if it is a
small wait).
