How to add memory management routines in driver RRS feed

  • Question

  • I am trying to include memory management routine(mmgetphysicalmemoryranges) into my driver.
    I don't know how to create driver object for physical memory and call these routines from my driver.

    I am aiming for displaying memory ranges in DbgView.
    Please help me.
    Thank you.

  • That is an undocumented routine reserved for system use, see

    Why do you believe your driver needs to get this information, there may be a better way to address the problem?

  • the PDRIVER_OBJECT is created for you and passed to you in DriverEntry. You can create PDEVICE_OBJECTs with IoCreateDevice calls, any sample will show this (or most likely the KMDF equivalents). But as don states, that is not the point. messing around with undocumented API calls leads to system instability,hangs and crashes (in all sorts of weird ways that don't directly point at your driver)
