Virtual CRTCs Are Brought Up Again

The discussion surrounding Virtual CRTCs has been renewed.

At the beginning of the month there was experimental code published for what was called Virtual CRTCs. The Linux kernel DRM code allows for fake/virtual CRTCs to be added to the DRM drivers for imaginary screens and comes from some research developers at Bell Labs.

Virtual CRTCs allow for some interesting possibilities for streaming contents between GPUs (e.g. this would help the NVIDIA Optimus situation) and very other interesting possibilities, as noted in the earlier article.

On Wednesday the discussion surrounding virtual CRTCs for Linux was brought up again. If you're interested in this topic, see this email thread on the mailing list. David Airlie had asked another question about the proposed code's design, and since then the discussion has been active once again. There's also some comments from the lead developer in our forums from earlier this month along with other possibilities for this un-merged Linux kernel code.

(Pardon for this message being terse as I have a train to catch to Vienna. For any Phoronix readers or Linux enthusiasts in Austria that would like to meet-up, I'll be at Mariahilferbräu near the Wien Westbahnhof. I'll be there beginning around 17.00 on Friday. Stefan Dösinger of CodeWeavers/Wine will also be there. After that [and tomorrow evening as well] there will be a meet-up at the Steigenberger Hotel Herrenhof bar. Contact me on Twitter for more details.)
