osSetTLBASIDFormat#include <ultra64.h> void osSetTLBASID(s32 asid); What This Function Does The osMapTLB, osUnmapTLB, osUnmapTLBAll, and osSetTLBASID functions manage CPU virtual address mapping. These calls provide low-level access to the CPU Translation Lookaside Buffer (TLB). The remainder of the CPU virtual address space outside of the direct mapped address spaces KSEG0 and KSEG1 are mapped address spaces that use the TLB to specify the mapping to physical memory on a per-page basis. The CPU TLB consists of 32 entries, which provide mapping to 32 odd/even physical page pairs (64 total pages). Each TLB entry is associated with a particular page size that varies from 4096 bytes to as much as 16 megabytes. The osSetTLBASID function sets a system-wide address space identifier register that makes valid only mappings of the given address space identifier (as well as global mappings). This feature can be useful for detecting address errors that may lead to unpredictable results. See Also osMapTLB osUnmapTLB osUnmapTLBAll osVirtualToPhysical
