Abstract
Systems, apparatuses, and methods for implementing a virtualized translation lookaside buffer (TLB) are disclosed herein. In one embodiment, a system includes at least an execution unit and a first TLB. The system supports the execution of a plurality of virtual machines in a virtualization environment. The system detects a translation request generated by a first virtual machine with a first virtual memory identifier (VMID). The translation request is conveyed from the execution unit to the first TLB. The first TLB performs a lookup of its cache using at least a portion of a first virtual address and the first VMID. If the lookup misses in the cache, the first TLB allocates an entry which is addressable by the first virtual address and the first VMID, and the first TLB sends the translation request with the first VMID to a second TLB.
