The KVM structure contains the global information of the corresponding VM, such as physical memory region, vcpus information, page table, memory management unit (MMU), I/O bus information, and the dirty translation lookaside buffer.
HYPER mode also allows the processor to read and write all virtual memory, 0x0000 0000 to 0xFFFF_FFFF, and to read and write the actual physical memory. These levels of privilege are typically visualized as rings (Figure 2).
Notice the focus of this API call is on sharing between the application memory (i.e., CPU memory) and the GPU, not the case of sharing between two APIs both executing their command streams on the same device with the same physical memory as shown in Figure 1.
Memory failure is also linked to the Reversion Effect since most memorization is tactile-dependent; therefore, physical memory deteriorates and the performer experiences memory-slips.
