We would like to have some interface to enumerate the GPU devices on the system, and select some specific device for different purposes (i.e, rendering, computing, displaying, etc). Current libdrm interfaces are just for single device, and there is no good consideration for multiple GPUs yet. > I believe I've read the same quote earlier, although still explains the goal, rather than the requirements :'-( Can you elaborate on what exactly the interface should provide - I can think of the following: - Number of devices. - ^^ + masked by vendor id/module name. This one seem like an overkill imho.. - Flags indicating if the device has primary/control/render node. - Location (bus info) for the device(s) - PCI/platform device information. Does the above cover all the things that you have planned for the interface to provide ?
