Not quite right, Terry is going to jump in here I am sure, is what needs to happen is the keyboard code needs to be ripped out of both syscons and pcvt and put in a separate driver. This new driver needs to handle the PS/2 mouse, and the keyboard, but nothing else. Understand that the way the hardware is built the PS/2 mouse really looks like it is part of the keyboard controller chip (and in fact on many machines it is inside the same chip). There is no such physical tie between the keyboard hardware and the video hardware so there should be no ties at the isa/ driver layer, but instead at a layer above that. This change would reduce a large chunk of duplicate code between pcvt, syscons and psm. There was tons of architectural discussion on what was once the console driver mailing list. I am sure Terry has this all rat holed some place on his system. That group of folks did come up with a very good layered architecture that should be used to fix this whole mess. > > Jordan > > > > > > Why there is no PS/2 mouse driver in the default kernel of > > 950412-SNAP ?
