Hello everyone,<div>   I am wondering whether it is possible to reserve a particular physical page in the kernel.</div><div>The GFP pages can start from _any_ location, and i cannot find a way to specify a starting pfn. </div>

<div>I need a few dozen pages to store a bitmap starting at a particular physical page frame number.</div><div>   Perhaps i am trying to do this wrong? I am trying to establish a (one-way) communication between KVM and a guest VM, by assuming that if KVM knows the physical address in the VM , it can access that bitmap. </div>

<div> </div><div>  Thanks ! </div><div><br></div>
