In most modern processors there are (at least) two primary modes of operation: user and kernel mode. In this model, applications operate in the user mode, while the operating system and hardware drivers operate in the kernel (or protected) mode. While user-mode drivers and APIs have the advantage of being a cross platform standard, they pay a performance penalty.
A non-reserved symbol that represents a category of usage or level of access to the current KB's knowledge. Declare a user mode simply by naming it in at least one configuration statement in at least one item in your KB. A G2 authorization file associates each authorized user name with a user mode.
Used in the gta exploit, prevents us from using certain functions e.g. UMD emulation and irda. No Flash Access within this mode.
A processor privilege level where the processor can't directly use resources, and must instead ask the kernel for access to a resource.
a mode that applies to you, the user
The processor execution mode in which privileged instructions (such as altering a control register) cannot be executed.
The processing mode in which applications run.
A nonprivileged processor mode in which application code runs.
A mode in which a process is carried out in the user's program rather than in the kernel. Contrast with kernel mode.
Non-privileged mode of the operating system where applications are run.
