Member Function Documentation

regStats()

void gem5::memory::DRAMInterface::DRAMStats::regStats ( )

overridevirtual

Callback to set stat parameters.

This callback is typically used for complex stats (e.g., distributions) that need parameters in addition to a name and a description. Stat names and descriptions should typically be set from the constructor usingo from the constructor using the ADD_STAT macro.

Reimplemented from gem5::statistics::Group.

Definition at line 1917 of file dram_interface.cc.

resetStats()

void gem5::memory::DRAMInterface::DRAMStats::resetStats ( )

overridevirtual

Callback to reset stats.

Reimplemented from gem5::statistics::Group.

Definition at line 1840 of file dram_interface.cc.
