all: Where can I find the patches and instructions for hot-remove for memory hotplug? For the test cases I need to be able to determine how much physical memory the system has without the memory being onlined, is there a way to do this? In the case that I am using acpi for the entry point, I need to be able to tell how many memory sections have been set up in the dsdt file, is there a way to do this(other than capturing, decompiling and then parsing the /proc/acpi/dsdt file)? I will also need a way to migrate pages in memory and then be able to verify that they have been successfully migrated, how would I go about that? Thanks Jake
