Introduction

This is a draft of the July–September 2015 status report. Please check back after it is finalized, and an announcement email is sent to the &os;-Announce mailing list.

This report covers &os;-related projects between July and September 2015. This is the third of four reports planned for 2015.

The third quarter of 2015 was another productive quarter for the &os; project and community. [...]

Thanks to all the reporters for the excellent work!

A new driver, ioat(4), was added to the tree. ioat(4) + supports Intel's I/O Acceleration Technology devices which are found + on some Intel server systems.

+ +

These devices are DMA offload engines, which can accelerate + some I/O-heavy applications by offloading memory copies from the main + CPU to the I/OAT unit. This acceleration is not transparent; + applications must be adapted to take advantage of the hardware.

+ +

Some I/OAT models support more advanced copying modes, like + XOR; these modes are not yet supported in the ioat(4) driver.

Further testing, especially on a range of device models other + than BDXDE (looking for volunteers here).

+ + + +

Support for the more advanced copy modes.
