Member Function Documentation

◆ ioctl()

int gem5::GPURenderDriver::ioctl ( ThreadContext tc,
unsigned  req,
Addr  buf 
)
inlineoverridevirtual

Abstract method, invoked when the user program calls ioctl() on the file descriptor returned by a previous open().

The parameters are the same as those passed in to ioctlFunc() (q.v.).

Returns
The return code for the ioctl, or the negation of the errno (see the SyscallReturn class).

Implements gem5::EmulatedDriver.

Definition at line 49 of file gpu_render_driver.hh.

◆ mmap()

Addr gem5::GPURenderDriver::mmap ( ThreadContext tc,
Addr  start,
uint64_t  length,
int  prot,
int  tgtFlags,
int  tgtFd,
off_t  offset 
)
overridevirtual

Virtual method, invoked when the user program calls mmap() on the file descriptor returned by a previous open().

The parameters are the same as those passed in to mmapFunc() (q.v.).

Returns
The return ptr for the mmap, or the negation of the errno (see the SyscallReturn class).

Reimplemented from gem5::EmulatedDriver.

◆ open()

int gem5::GPURenderDriver::open ( ThreadContext tc,
int  mode,
int  flags 
)
overridevirtual

Abstract method, invoked when the user program calls open() on the device driver.

The parameters are the same as those passed to openFunc() (q.v.).

Returns
A newly allocated target fd, or -1 on error.

Implements gem5::EmulatedDriver.
