NVIDIA Publishes A New Open-Source Nouveau Driver Patch

A short time ago NVIDIA made the bold move of working on open-source Tegra K1 graphics support for Nouveau, the reverse-engineered open-source NVIDIA driver they previously took a neutral approach to handling. The Tegra K1 Nouveau support is still being worked on but there's a fresh patch out of NVIDIA for the open-source developers.

Tegra K1 is NVIDIA's forthcoming Tegra ARM SoC update and it's very exciting since it should be extremely fast, there will be a 64-bit ARM version, and the graphics are Kepler-derived. The new patch out of NVIDIA for Nouveau isn't about the K1 specifically but it's groundwork that must be laid within Nouveau for supporting the K1.

The patch sent in on Sunday night by NVIDIA's Alexandre Courbot is continued work on support for platform devices. Up to now the Nouveau driver is centered around PCI devices but platform device support needs to be added for supporting the mobile Kepler GPUs.

Alexandre is hoping this patch will be merged soon since there were no objections to its original posting when announcing the Nouveau GK20A work and since it touches many subsystems it will be easier on maintenace to merge it sooner rather than later.

This NVIDIA patch for Nouveau can be found on the dri-devel list and will likely appear then in the Linux 3.15 kernel assuming no objections are raised.
