We don't relocate resources unless we need to. So that ball's as > much in your court as it is in ours. Any X reassignment of PCI resources is unsafe in Linux 2.4, and going to get more so. The DGA comemnt applies here the other way around - you don't currently have a way to get the kernel to do the work for you. We need to address that. X doesn't know enough hw issues or locking > As to hot-plugging video adapters, very few of them, if any, can handle it > anyway. And I don't see hot-plug as a high priority for the likes of ATI > and nVidia. My extreme hotplug test set for 2.5.66 + rmk patches is a ten head hot plugged video setup including 2 quad head S3 cards and a pair of C&T cards. Total ebay cost < $400. (Kudos to the X guys - XFree86 4.3 can't hotplug this lot but it can run it) My off the shelf example is the mobility cardbus docking station which has a hotplug ATI rage. Our framebuffer drivers can handle some of these hot docks. A voodoo2 in a thinkpad docking station works correctly kernel side. The kernel also has the framework to report new PCI devies to XFree86 as well as device removal. Alan
