![]() This is because the windows thread scheduler loads CR3 from KPROCESS->DirectoryTableBase. trapped registers, notice no CR3.Īs you can see from above, CR3 is not included in this trap frame. If a LP gets interrupted in CPL0 the KTRAP_FRAME is just used. When a LP gets interrupted in usermode, the trap frame KUMS_CONTEXT_HEADER is used, this also contains a KTRAP_FRAME. When a LP gets interrupted and rescheduled, all general purpose registers are moved into a trap frame, which is then located inside of the KTHREAD.

On Windows, each process has its own virtual address space. Control Register Three (CR3) contains the PFN (Page Frame Number) of the current Page Map Level Four (PML4). In this post I will be referring to an address space in reference to a 64bit virtual address space on x86 architecture.
