I am working on a SandyBridge Processor.
I want to change the row-buffer management policy of IMC.
Currently It uses a closed page policy. I know that IMC uses
an adaptive paging policy.
But I want to make it open page. The only option I could think of
is writing to the PCI Device Register which has a configurable
Bit set for choosing Paging Policy. But doing it online will be stupid.
My Bios does not have any option for such a change. The only
option it has is to change memory interleaving policy.
Any suggestions is deeply appreciated.
