IOCTL_GNSS_EXECUTE_SELFTEST IOCTL (gnssdriver.h)
The IOCTL_GNSS_EXECUTE_SELFTEST control code is used by the GNSS manufacturing test application to initiate a self test in the GNSS lower stack.
Major code
Input buffer
A pointer to a GNSS_SELFTESTCONFIG structure.
Input buffer length
Set to sizeof(GNSS_SELFTESTCONFIG).
Output buffer
A pointer to a GNSS_SELFTESTRESULT structure.
Output buffer length
Set to sizeof(GNSS_SELFTESTRESULT).
Status block
Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful. Otherwise, Status to the appropriate error condition as a NTSTATUS code.
Remarks
GNSS test application notes
The GNSS test application must wait for a status response from the test, and be resilient to the GNSS driver not responding.GNSS driver notes
The GNSS driver must fail a new self test session request if there is already a test in progress.Once the GNSS driver accepts the self test session parameters, validates them and starts the test in the GNSS engine. The GNSS driver completes the I/O request after completing the tests and returning the status to the GNSS test application.
