WebDec 23, 2024 · Intel architectures divide virtual memory into 4KB pages(with support for other sizes) and physical memory into 4KB frames. An MMU will typically contain a translation lookaside buffer(TLB) and will perform operations on the page table such as hardware table walks. Some MMU architectures will not perform those operations. WebGenerate fast-path TLB refill exception handler which loads host TLB entries from GVA page table, avoiding repeated guest memory translation and guest TLB lookups commit. Use uaccess macros when T&E needs to access guest memory, which with GVA page tables and the Linux TLB refill handler improves robustness against TLB faults and fixes EVA ...

WebJul 22, 2024 · Since a host might allocate DMA buffers on physical addresses that are beyond the 32-bit range (regardless of its virtual address), a solution was necessary to ensure that these PCI devices would still work. The IOMMU solves this problem by creating a separate virtual memory map for each PCI device, based upon its bus ID.

WebIn addition to translating a guest’s physical address to a host’s physical address, EPT specifies the privileges that software is allowed when accessing the address. Attempts at disallowed accesses are called EPT violations and cause VM-exits.
