Hi! Some vnc clients has '-via ssh_gateway' option to simplify the setup of ssh port forwarding. Basically the option implements the following 3 steps: 1. Find local port available for listening. 2. Fork/exec ssh -L found_port:vnc_host:vnc_port ssh_gateway sleep some_delay 3. Connect to the found_port Although convenient the setup has its problems. First, it exposes the remote vnc port for everybody on the localhost for the duration of some_delay. Second it can cause connection at step 3 to fail if it would take a lon...

This is the series I've been working on for a while now to get all of the atomic DRM drivers in the tree to use the atomic MST helpers, and to make the atomic MST helpers actually idempotent. Turns out it's a lot more difficult to do that without also fixing how port and branch device refcounting works so that it actually makes sense, since the current upstream implementation requires a

Hello, I have my work on the nv vpe video decoder in a functional state. In case you didn't know this decoder accelerates mpeg2 video at the idct/mc level. I have verified that it works on nv40 hardware. I believe it works on nv30 hardware (and maybe some earlier hardware), but I cannot verify since I have none. I will reply with patches against the kernel, drm, ddx and mesa for
