My user space driver need to call a function: clock_get_calendar_microtime(&currentTime_sec,&currentTime_usec); I hope Xcode DriverKit library can include "kern/clock.h"

I am working on SCSIControllerDriverKit IOUserSCSIParallelInterfaceController When the MacOS system restarts or shuts down, Why DriverKit SetPowerState is not called? But when the MacOS system sleeps and wakes up, SetPowerState is called. kern_return_t IMPL (MyUserSpaceDriver, SetPowerState) { ....... }

I am woriking on SCSIControllerDriverKit IOUserSCSIParallelInterfaceController When I hot-plug my PCIe SCSI controller, the controller works normally, but when I hot remove the PCIe SCSI controller, the driverkit crashes.

I am working on SCSIControllerDriverKit UserSpaceDriver-UserCreateTargetForID.ips.txt I UserSpaceDriver-UserCreateTargetForID.rtf.txt OUserSCSIParallelInterfaceController My dext had follow this site description: https://developer.apple.com/documentation/scsicontrollerdriverkit/iouserscsiparallelinterfacecontroller/3567474-usercreatetargetforid But when the program calls: UserCreateTargetForID(scsi_target,targetOSDictionary) got panic.
