By adjusting dimensions, such as the length and width of the saw bow legs and an area defined by the saw bow legs, as well as a shape of the etch region through techniques such as chamfering, plasma etch speed in the region can be controlled with an intent to match the speed of etching in non-over-etched regions.

Abstract: A method is provided in a data processing system having second level address translation (SLAT) controlled by a hypervisor. In the method, hashes of all memory pages accessible by a guest OS are stored (set S). Also, hashes of all memory pages previously accessed by the guest OS are stored (set T). When the guest OS attempts an access to a memory page having executable code for which it does not have permission, an exception is generated. A hash of the memory page is compared with the hashes of set T and set S. If there is not a match within set T, then the guest OS has never attempted the requested operation before and suspicious behavior is reported. If there is not a match within set S, the requested operation is reported as illegal. In another embodiment, the memory page may be encrypted to prevent the guest OS from reading the memory page.
