Non-Transparent Bridges allow creation of memory windows between + different systems, using the regular PCIe links of CPUs as a + transport. During the last quarter, the NTB subsystem gained a + significant set of improvements and fixes:

+ +
    +
  • The code was modularized, utilizing &os;'s NewBus interfaces + to allow support for different hardware types with different + drivers, support for multiple NTB instances in a system, + using the ntb_transport module for consumers other + than if_ntb, etc.
    • + +
  • Support for splitting NTB resources between different + applications was added, such as doing direct access to some range + of remote memory and to a virtual network interface between nodes + at the same time, etc.
    • + +
  • The virtual network interface driver gained support for many + modern features, such as multiple queues, new locking, etc.
    • + +
  • NTB performance and SMP scalability was improved.
    • + +
  • Multiple workarounds for hardware issues were added.
    • +
+ +

The code is committed to the &os; head, stable/11 and stable/10 + branches.

+ + + + The project is sponsored by iXsystems, Inc. + + + + Support for the next generation of Intel hardware. + + Support for non-Intel hardware (AMD, PLX, etc.). + + Support for I/OAT and other DMA offloads. + + Creating a more efficient packet transport protocol. + + Creating a greater variety of NTB applications. + +
