What's needed is a dual memory layout settup for the next minor version. This would payve the way to release the next major version, if minor >= x will be forward compatible to the new major. I would say to have dual memory layout support for the DRM would be a gross wast of kernel resorces. So it will be up to X server and clients to carry the burdon of having the new configuration. I know there is allready a dispatch table for clients, could we have 2 radeon drivers? For the ONE(currently active) Xserver it seams as thought just a select for dispatching would be a temporary solution. How long would we need to maintain the proposed hack? Would all the developers be willing to switch to the new major version once it's working front and back? Is gatos's DRM up to the challenge or dose it need work so it can replace the current?
By dual memory layout I'm saying that the client/X would have 2 drivers one for the old kernel and one for the new. My time is limited, I should be working or even trying to find a real job. Though it's hard to sleep when I know my compurter has problems that could be fixed. __________________________________ Do you Yahoo!? Yahoo!
