http://xillybus.com/tutorials/iommu-swiotlb-linux WebThis patch series adds a new swiotlb implementation, cc-swiotlb, for Confidential VMs (such as TDX and SEV-SNP). The new cc-swiotlb allocates the DMA TLB buffer dynamically in runtime instead of allocating at boot with a fixed size. Furthermore, future optimization and security enhancement could be applied on cc-swiotlb without … WebAug 20, 2024 · - the "swiotlb=" is configured to allocate extra buffer, and - the SWIOTLB_EXTRA is set in the flag (this is to make sure arch (s) other than x86/sev/xen will not enable it until it is fully tested by each arch, e.g., mips/powerpc). Currently it is enabled for x86 and xen. 3. During swiotlb map, whether zone [0] (32-bit) or zone [1] (64-bit flymo vibration problems
