XvioSetFocus function

Used for setting to another partition. Likely used for switching between SystemOS and GameOS.
It's weird this function is implemented in xvio.sys rather than xvmctrl.sys as it simply just posts a message to the Xbox VM Manager.

Syntax

C++

NTSTATUS XvioSetFocus(
    uint64_t TargetPartition
);

Parameters

uint64_t TargetPartition
The target partition to focus. See partition identifiers for more info.

Return value

Returns a standard NTSTATUS value.

Important notes

Cannot be called from GameOS, and will just return STATUS_ACCESS_DENIED if this is attempted.
