Doesn't physical adress extension (PAE) circumvent this problem? Then you are just limited to 4GB per process (or thread, can't remember), but that's a lot better.
- wolfgke 10y agoPhysical adress extension (PAE; https://en.wikipedia.org/wiki/Physical_Address_Extension https://en.wikipedia.org/wiki/Physical_Address_Extension) is a feature of x86 CPUs, not ARM ones.
- monocasa 10y agoARMv7a has the same thing (called LPAE by ARM). http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0438d/CHDCGIBF.html http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.... That being said, the Cortex A9 in the iMX6 doesn't support that, and therefore it only supports 3840MB (4GB minus a hole for ROM and MMIO).
