Why do we need patches in the kernel. Just set you config to CONFIG_DUMMY_CONSOLE, CONFIG_FB, CONFIG_INPUT and don't set fbcon or vgacon. Then have a userspace app using /dev/fb and /dev/input create a userland console. There is no need to do special hacks in the kernel./dev/fb is not accelerated, if you want full acceleration use /dev/dri. Using /dev/dri you can write a fully composited console that displays dengavi in realtime. This is also a path to getting multiuser working without a lot of kernel patches.Not every device has a 3D core!!! DRM is not the answer for the entire graphics world. Its only for 3D functionality. If you want eye candy without 3D on small devices use fbdev.
DRM doesn't know a thing about 3D. All it does is DMA, memory management and queue things up for the GPU to work on. You don't even have to have a GPU processor you could use the CPU to execute the commands. It's the code up in mesa that knows about 3D and builds the commands to be sent to DRM. -- Jon Smirl jonsmirl@gmail.com ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
