The function RtcplEditRTXDeviceInfo edits an RTX device’s properties.
Syntax
BOOL RtcplEditRTXDeviceInfo(
PDEVICEINFO_DATA DevData
);
Parameters
DevData
Pointer to a DEVICEINFO_DATA data structure that contains information about the device pointed to in the DevData member.
Return Values
A non-zero value if the function succeeds
Remarks
These values can only be edited on an ACPI system that supports IRQ steering.
RtcplEditRTXDeviceInfo depends on both the DEVICEINFO and DEVICEINFO_DATA structures. At a minimum, the HardwareId parameter in the DEVICEINFO structure must be filled in. Also, the only editable fields in the DEVICEINFO_DATA structure are IRQ, Disposition, and KeepLineBasedAvailable. All three editable fields must be set to the correct value, because all fields are written when the edit function is called. KeepLineBaseAvailable is only modified if MSICapable is TRUE.
Finally, if you set the IRQ value to 0, the RTX PNP driver will try for any IRQ it can get.
