Various embodiments can control access to a computing resource (e.g., a memory resource) by detecting that a high priority activity is accessing the resource and preventing a lower priority activity from accessing the resource. The lower priority activity can be allowed access to the resource after the high priority activity is finished accessing the resource. Various embodiments enable memory operations to be mapped to account for changes in data ordering that can occur when a lower priority activity is suppressed. For example, when an activity requests that data be written to a logical memory region, a mapping is created that maps the logical memory region to a physical memory region. The data can then be written to the physical memory region.
