Hi All, I would like to pass hints in my binary to tell the memory system it needs to do work at a specific address. Currently I am doing this by writing the specified address to a global variable used only for this purpose. From the memory system, I am then intercepting the packets that are writing to the global variable. The address I need to work with is pointed to by the data pointer of the packet. The problem I am running into is the address is a virtual address, and a physical address is needed in the memory system. Can anyone explain the translation process and give any hints as to how I could translate a virtual address either from the packet, or before the data is added to the packet on the cpu side of the memory request? Also, if I have overlooked any more straightforward approach to passing similar hints to the memory system any help there would be appreciated also. Thanks for your time.
