All, My name is Larry Schiefer and I am a software engineer for Intelligraphics, Inc. We specialize in device driver and embedded system development.
Currently, I am working for a client brining up MontaVista Linux on their custom MIPS based platform. MV Linux runs a bit behind the latest kernels available, so it is running an older 2.4 version. My customer needs to have the large throughput capabilities of the USB 2.0 drivers available for the 2.6 kernel. In particular, they need to be able to write to USB hard disks at very high data rates (> 10MB/sec). Unfortunately, these higher data rates are not being achieved, which caused me to look around a little. The Linux USB website had a short description about a change made to the USB 2.0 core and usb-storage drivers to support large I/O scatter lists at once. According to the description, this was introduced in 2.5.45 and is available in the 2.6 kernels. Looking through the latest 2.4 stable release (2.4.28) as well as the MV Linux kernel shows none of the scatter-gather changes, so I have the following questions: 1. Are there plans to back-port the scatter-gather change to the 2.4 kernel tree? 2. Is there something in the scatter-gather change that restricts it from being back-ported to the 2.4 kernel? Thanks in advance for any assistance you can lend. Best Regards, Larry -- ___________________________________ Larry Schiefer Senior Software Engineer Intelligraphics, Inc.
