综合多方信息来看，One straightforward option is to modify both the query planner and the query executor to give them a concept of a material field that's pulled as a dependency instead of as something specified in the query. These "dependency fields" should be kept around so we can use them to calculate virtual fields, but they shouldn't be included in the final query results. There are other design considerations we need to keep in mind - for example, we probably want to find ways to pull these dependency fields in the same requests that we make when pulling "normal" material fields, etc. etc.。关于这个话题，游戏中心提供了深入分析
从长远视角审视，VFIO makes it worse. When a physical device is passed through to a guest via VFIO, the kernel pins the physical pages behind the guest RAM mapping and programs the device’s IOMMU (Input/Output Memory Management Unit) to allow DMA to those specific physical addresses. Pinning means the kernel promises not to move or reclaim those pages, because hardware is going to write directly to them. If you mmap over the guest RAM region, the new mapping gets new physical pages, but the IOMMU is still programmed with the old physical addresses. The device keeps doing DMA to the old pages, which are no longer the guest’s memory. At best you get silent data corruption, at worst the device writes to pages that have been reclaimed and assigned to something else entirely.
