In 2.6 1. If you use fbset, you will get screen corruption or hang the GPU 2. stty will do the function of fbset. However, stty will only pass rows and cols (xres and yres respectively). There is no information for bit depth, timings, virtual resolution, etc.So *this* is what's going on with my port of the cirrusfb driver--why fbset wasn't working... for radeonfb fbset still works in 2.6, so i didn't realize there was this problem... What's so wonky with the fbset code path that screws things up? and why does stty work?
The flow of fbset is upstream: fbset->fbdev->fbcon->vc (2.4 code) The flow of stty is downstream: stty->vc->fbcon->fbdev (2.6 code) I don't know how radeonfb does it though.
