Hello.
I am watching the KMS in DRM development. And now i want to try kernel
modesetting with framebuffer console.
I am only using console framebuffer. How it works with DRM KMS.
Suppose I compile DRM i1915 with KMS. How can I swich video mode on start
and than from user space.
Normally with framebuffer it is IOCTL on /dev/fb. Will it work or not?
Some explantion should ne enough, thanks

Just works. The kms code supports the fb interface.

Loading the driver switches to the native resolution of the lcd monitor
connected and runs a fbcon on it. Didn't try to switching modes later.
HTH,
