A device driver is usually G configured automatically by OpenVMS, when the system autoconfiguration  N processing runs through its configuration sequence -- probing the contents of N the attached buses.   If the device CSRs are set correctly (and correctly for J the whole flock of controllers present on a Q-bus or Unibus, and that's a I requirement based on the way the configuration processing works with the  M floating CSR model implemented on these older buses), you'll either have the  F DN11 device driver connected, or you'll not have the device connected.  N    Device drivers can and do use probe, but usually for accessing user memory K and rather less commonly in CSR space, which is where the device announces  J itself.  (Most drivers usually know the layout of the associated device's O control and status register(s) (CSR(s)), and use  addressing details retrieved  M out of the DDB and UCB.  When messing in bus memory  space, it's usually via  J allocation routines written into bitfields within the  CSR, so the driver ) (still) knows where the memory space is.)   P    If within a VAX device driver, you'll want to use a machine check protection Q   block, see the $PRTCTINI/$PRTCTINI mechanism in the OpenVMS VAX device driver.  O   (Can't say I've ever tried this sequence looking for an emulated Unibus DN11  & on  an emulated VAX; only with VAXBI.)  &    At DCL, there's f$getdvi("EXISTS").  O    With typical system services and user-mode code, just aim a sys$getdvi (for  Q whatever) and catch the error that would get returned for a non-existent device.  ; I'd tend to expect to see the SS$_NOSUCHDEV condition here.   M    User-mode code can also occasionally get rather more directly involved in  J this area and in kernel-mode memory access, but it's usually via directly K mapping the device.  (I'm guessing you are not mapping the device from the  M user-mode code via the OpenVMS VAX CONINTERR connect-to-interrupt mechanism.  P This particular interface mechanism never really made it across to OpenVMS AlphaP or OpenVMS I64, but we are discussing OpenVMS VAX here so it's a possibility...)  L    I might guess that this situation is a case where whatever host software P accesses the (missing) DN11 "control" device, and gets itself into some sort of H a loop. Accordingly, I'd be looking at the error path(s) in whatever is L accessing the DN11 "control" device.  (And I'm inferring rather much here.) M This situation and this approach doesn't involve any sort of physical memory  M probe, if it's user-mode code attempting to access a device.  I've certainly  P encountered cases where a missed or mishandled test has caused the code to head O into the weeds, and has generated I/O spikes.  There's a list of common coding  S errors over in (1661) of the Ask The Wizard area, if that might help with a review.    ------------------------------   End of INFO-VAX 2006.552 ************************
