Member Function Documentation

physical_uintptr_t MemFile::getPhysicalPage ( size_t offset )

virtual

Get the physical address for the given offset into the file. Returns (physical_uintptr_t) ~0 if the offset isn't in the cache.

Reimplemented from File.

Definition at line 464 of file DevFs.cc.

References Hex, and NOTICE.

void MemFile::returnPhysicalPage ( size_t offset )

virtual

Specifies that the system is done with the physical page retrieved from getPhysicalPage now. Allows the physical page to be evicted from the file cache again.

Reimplemented from File.

Definition at line 474 of file DevFs.cc.

References InputManager::instance(), and InputManager::removeCallback().
