addr

- instruction address

instSize

- instruction size (32 or 64 bits)

buf

- disassembled instruction buffer

sz

- disassembled instruction buffer size

Returns

Since CUDA 6.0.

Parameters

devId

- device index

handle

- elf image handle

type

- type of the requested ELF image

elfImage

- pointer to the ELF image

size

Returns

CUDBG_SUCCESS, CUDBG_ERROR_INVALID_ARGS, CUDBG_ERROR_INVALID_DEVICE, CUDBG_ERROR_UNINITIALIZED

CUDBGResult ( *CUDBGAPI_st::getHostAddrFromDeviceAddr )( uint32_t dev, uint64_t device_addr, uint64_t* host_addr )

Parameters

dev

- device index

device_addr

- device memory address

host_addr

- returned system memory address

Returns

CUDBGResult ( *CUDBGAPI_st::getPhysicalRegister30 )( uint64_t pc, char* reg, uint32_t* buf, uint32_t sz, uint32_t* numPhysRegs, CUDBGRegClass* regClass )

Get the physical register number(s) assigned to a virtual register name 'reg' at a given PC, if 'reg' is live at that PC. Since CUDA 3.0.

Parameters

pc

- Program counter

reg

- virtual register index

buf

- physical register name(s)

sz

- the physical register name buffer size

numPhysRegs

- number of physical register names returned

regClass

- the class of the physical registers

CUDBGResult ( *CUDBGAPI_st::getPhysicalRegister40 )( uint32_t dev, uint32_t sm, uint32_t wp, uint64_t pc, char* reg, uint32_t* buf, uint32_t sz, uint32_t* numPhysRegs, CUDBGRegClass* regClass )

Get the physical register number(s) assigned to a virtual register name 'reg' at a given PC, if 'reg' is live at that PC. Get the physical register number(s) assigned to a virtual register name 'reg' at a given PC, if 'reg' is live at that PC. If a virtual register name is mapped to more than one physical register, the physical register with the lowest physical register index will contain the highest bits of the virtual register, and the physical register with the highest physical register index will contain the lowest bits.

Since CUDA 3.1.

wp

- warp indx

pc

- Program counter

reg

- virtual register index

buf

- physical register name(s)

sz

- the physical register name buffer size

numPhysRegs

- number of physical register names returned

regClass

- the class of the physical registers
