WebThe legacy swiotlb cannot efficiently support larger swiotlb buffers. In the worst case, the current implementation requires a full scan of the entire swiotlb buffer, which can cause severe performance hits. Instead of keeping "infecting" the legacy swiotlb code with CoCo logic, this patch tries to introduce a new cc-swiotlb for Confidential VMs. WebI meant swiotlb_map_single() should either panic or simply fail. If I have read lib/swiotlb.c correctly the only place we allocate a bounce buffer is in swiotlb_map_single. If there are more places we can allocate bounce buffers those need to be handled as well.
