In the various aspects, virtualization techniques may be used to improve performance and reduce the amount of power consumed by translating virtual memory addresses into physical addresses on a computing system having hybrid memory. In a first stage of memory translation, an operating system translates virtual addresses to intermediate physical addresses. In a second stage of memory translation, a chip or virtualization software translates the intermediate physical address to physical addresses based on the characteristics of the physical memory and the characteristics of the processes associated with the physical memory.

The disclosure is directed to managing registration of a wireless communication device (WCD) operating in a wireless network. The WCD may support registration according to a signaling protocol, such as session initiation protocol (SIP). The WCD adjusts a registration timer based on network quality experienced by the WCD. When network quality is poor, for example, the WCD reduces the length of the registration timer. Reduced network quality may indicate that the WCD is at risk of losing network coverage. By reducing the length of the registration timer when network quality is degraded, stale registrations for out-of-coverage WCDs can be reduced. In particular, the shortened registration timer will expire more quickly, permitting the registration to be cleared more quickly. Consequently, the amount of call forwarding and other resources devoted to stale registrations can be reduced. If the WCD retains network coverage, it can maintain a registration by sending another registration request.
