Hi,
I'm working on a research project for dynamic voltage/frequency scaling for DRAM.
I am aware that coreboot initializes DRAM and sets its frequency (cache-as-ram) during boot. I would like to know if it is possible to change the DRAM frequency by following the same initialization sequence without rebooting the system (along with preserving the application's memory context).
Thanks, Tapasya Patki
I think it depends on the memory controller and how much system control you have at the point you wish to make the change.
