Constructor & Destructor Documentation

◆ Process()

gem5::Process::Process ( const ProcessParams &  params,
EmulationPageTable pTable,
loader::ObjectFile obj_file 
)

Linux bundles together processes into this concept called a thread group. The thread group is responsible for recording which processes behave as threads within a process context. The thread group leader is the process who's tgid is equal to its pid. Other processes which belong to the thread group, but do not lead the thread group, are treated as child threads. These threads are created by the clone system call with options specified to create threads (differing from the options used to implement a fork). By default, set up the tgid/pid with a new, equivalent value. If CLONE_THREAD is specified, patch the tgid value with the old process' value.

Member Function Documentation

◆ absolutePath()

std::string gem5::Process::absolutePath ( const std::string &  path,
bool  host_fs 
)

Return an absolute path given a relative path paired with the current working directory of the process running under simulation.

Parameters
pathThe relative path (generally a filename) that needs the current working directory prepended.
host_fsA flag which determines whether to return a path for the host filesystem or the filesystem of the process running under simulation. Only matters if filesysem redirection is used to replace files (or directories) that would normally appear via the host filesystem.
Returns
String containing an absolute path.

◆ checkPathRedirect()

std::string gem5::Process::checkPathRedirect ( const std::string &  filename)

Redirect file path if it matches any keys initialized by system object.

Parameters
filenameAn input parameter containing either a relative path or an absolute path. If given a relative path, the path will be prepended to the current working directory of the simulation with respect to the host filesystem.
Returns
String containing an absolute path.

◆ clone()

void gem5::Process::clone ( ThreadContext old_tc,
ThreadContext new_tc,
Process new_p,
RegVal  flags 
)
virtual

Share the process memory address space between the new process and the old process. Changes in one will be visible in the other due to the pointer use.

Duplicate the process memory address space. The state needs to be copied over (rather than using pointers to share everything).

The parent and child file descriptors are shared because the two FDArray pointers are pointing to the same FDArray. Opening and closing file descriptors will be visible to both processes.

Copy the file descriptors from the old process into the new child process. The file descriptors entry can be opened and closed independently of the other process being considered. The host file descriptors are also dup'd so that the flags for the host file descriptor is independent of the other process.

◆ drain()

DrainState gem5::Process::drain ( )
overridevirtual

Draining is the process of clearing out the states of SimObjects.These are the SimObjects that are partially executed or are partially in flight.

Draining is mostly used before forking and creating a check point.

This function notifies an object that it needs to drain its state.

If the object does not need further simulation to drain internal buffers, it returns DrainState::Drained and automatically switches to the Drained state. If the object needs more simulation, it returns DrainState::Draining and automatically enters the Draining state. Other return values are invalid.

Note
An object that has entered the Drained state can be disturbed by other objects in the system and consequently stop being drained. These perturbations are not visible in the drain state. The simulator therefore repeats the draining process until all objects return DrainState::Drained on the first call to drain().
Returns
DrainState::Drained if the object is drained at this point in time, DrainState::Draining if it needs further simulation.

Implements gem5::Drainable.

◆ map()

bool gem5::Process::map ( Addr  vaddr,
Addr  paddr,
int  size,
bool  cacheable = true 
)

Maps a contiguous range of virtual addresses in this process's address space to a contiguous range of physical addresses.

This function exists primarily to expose the map operation to python, so that configuration scripts can set up mappings in SE mode.

Parameters
vaddrThe starting virtual address of the range.
paddrThe starting physical address of the range.
sizeThe length of the range in bytes.
cacheableSpecifies whether accesses are cacheable.
Returns
True if the map operation was successful. (At this point in time, the map operation always succeeds.)
