Since the last report &os; support for ThunderX has been + significantly improved and stabilized. Semihalf contributions + include the following items:

+ +

Support for the newest ThunderX chip revisions (Pass 2.0) + and current Cavium firmware. Backward compatibility is + maintained.
Moved to using pci_host_generic.c as a main driver for the + internal PCIe bridge. Significant rework of PCIe code to + support both generic and ThunderX based platforms.
Serious networking performance boost and bug fixes:

Fixed race condition on Rx path causing very rare + ‘use after free’ issue
Hardware L3 and L4 checksums support
Hardware assisted TCP Segmentation Offloading + (TSO)
Support for software Large Receive Offload (LRO)
Various improvements to Tx and Rx paths and + configuration

+ +

The driver supports all available Ethernet connections (1, + 10, 30 Gbps) and system can can saturate 10 Gbps link (on Tx) + using 4 CPU cores.

+ +

Significantly improved overall I/O performance:

Complete rework of copyin/copyout and bzero + functionalities

Other improvements:

Support for interrupt to CPU binding (including + GICv3/ITS backends)

+ +

This work is integrated to the FreeBSD HEAD on on-going + basis.

Support for multi Queue Set operation in VNIC
