- Optimizes the IOVA page table lookup and release algorithms to improve the performance of the IOMMU subsystem.
- Optimizes the implementation of CRC32 and checksum based on ARM64 instructions and pipeline features, greatly improving data verification performance.
- Supports ARM v8.4 Memory System Resource Partitioning and Monitoring \(MPAM\).
- virtualization feature enhancement
- Interruption virtualization optimization: The process for an IRQfd to inject an interrupt is optimized, greatly improving the performance of high-performance passthrough devices (sush as NICs and SSDs).
- Memory virtualization optimization: The Kunpeng hardware feature is used to improve the memory loading speed during VM startup.
- Storage virtualization optimization: NUMA affinity self-binding is optimized for the iSCSI module **kworker** to improve the I/O performance of IP SAN disks.
