变量

CUDBGResult ( *CUDBGAPI_st::writeCCRegister )( uint32_t dev, uint32_t sm, uint32_t wp, uint32_t ln, uint32_t val ): Writes the hardware CC register.
CUDBGResult ( *CUDBGAPI_st::writeGenericMemory )( uint32_t dev, uint32_t sm, uint32_t wp, uint32_t ln, uint64_t addr, const void* buf, uint32_t sz ): Writes content to an address in the generic address space. This function determines if the given address falls into the local, shared, or global memory window. It then accesses memory taking into account the hardware co-ordinates provided as inputs.
CUDBGResult ( *CUDBGAPI_st::writeGlobalMemory )( uint64_t addr, const void* buf, uint32_t sz ): Writes content to an address in the global address space. If the address is valid on more than one device and one of those devices does not support UVA, an error is returned.
CUDBGResult ( *CUDBGAPI_st::writeGlobalMemory31 )( uint32_t dev, uint64_t addr, const void* buf, uint32_t sz ): Writes content to address in the global memory segment.
CUDBGResult ( *CUDBGAPI_st::writeGlobalMemory55 )( uint32_t dev, uint32_t sm, uint32_t wp, uint32_t ln, uint64_t addr, const void* buf, uint32_t sz ): Writes content to address in the global memory segment (entire 40-bit VA on Fermi+).
CUDBGResult ( *CUDBGAPI_st::writeLocalMemory )( uint32_t dev, uint32_t sm, uint32_t wp, uint32_t ln, uint64_t addr, const void* buf, uint32_t sz ): Writes content to address in the local memory segment.
CUDBGResult ( *CUDBGAPI_st::writeParamMemory )( uint32_t dev, uint32_t sm, uint32_t wp, uint64_t addr, const void* buf, uint32_t sz ): Writes content to address in the param memory segment.
CUDBGResult ( *CUDBGAPI_st::writeRegister )( uint32_t dev, uint32_t sm, uint32_t wp, uint32_t ln, uint32_t regno, uint32_t val ): Writes content to a hardware register.
CUDBGResult ( *CUDBGAPI_st::writeSharedMemory )( uint32_t dev, uint32_t sm, uint32_t wp, uint64_t addr, const void* buf, uint32_t sz ): Writes content to address in the shared memory segment.
CUDBGResult ( *CUDBGAPI_st::writeUniformRegister )( uint32_t dev, uint32_t sm, uint32_t wp, uint32_t regno, uint32_t val ): Writes content to a uniform register.
