Hi all, I'm a student accepted with proposal "Generic DMA engine framework for FreeBSD". I'm on second year computer science studies at Jagiellonian University in Poland. This summer I'll add generic mechanism for using general purpose DMA engines found in embedded system-on-chip devices. This will make possible to schedule transfers from kernel and userspace and will allow to use DMA in other devices using systemwide DMA engine. My earlier experience with kernel development was writing FreeBSD/arm port to TI DaVinci Digital-media system-on-chip - more details here: [1]. Development of this project will be done also on DaVinci - I'll provide implementation of its DMA engine as well as example DMA-enabled device driver - DaVinci's SD/MMC controller (current implementation uses only PIO transfers). You can read more details here: http://wiki.freebsd.org/SOC2010JakubKlama I will appreciate your comments and suggestions about this project.
