The absense of IN_RC and IN_GUEST + * indicates that we're in HC. IN_RING0 indicates ring-0 (kernel) and + * IN_RING3 indicates ring-3. + * - Raw-mode Context (RC) - This is the special VMM context where we + * execute the guest code directly on the CPU. Kernel code is patched + * and execute in ring-1 instead of ring-0 (ring compression). Ring-3 + * code execute unmodified. Only VMMs use ring-1, so we don't need to + * worry about that (it's guarded against in the scheduler (EM)). We can + * in theory run ring-2 there, but since practially only only OS/2 uses + * ring-2, it is of little importance. The macro IN_RC indicates that + * we're compiling something for RC. + * Note! This used to be called GC (see below) earlier, so a bunch of RC + * things are using GC markers. + * - Guest Context (GC) - This is where the guest code is executed. When + * compiling, IN_GUEST indicates that it's for GC. IN_RING0 and + * IN_RING3 are also set when applicable, these are accompanied by + * IN_GUEST_R0 and IN_GUEST_R3 respecitively. + * - Intermediate context - This is a special memory context used within + * the world switchers (HC -> RC and back), it features some identity + * mapped code pages so we can switch to real mode if necessary. + * + */ + -- cgit v1.2.3
