When I proposed this a couple of months back both you and Linus called me insane. I need to go find those posts. This logical conclusion at the end of this is a user space console. It makes the problem of multi-user Linux simple to implement. Via OpenGL you also get full acceleration. If it is coordinated with xserver you can make your VT's appear as windows. There is still a master kernel based console that handles boot, printk, oops and kdbg. Each head will use the kernel based console to implement SAK. Ctrl-Alt-Del gets you SAK, SysReq get you the kernel console. No logins on the kernel console it is write only, SAK will start the user space console. The kernel console and SAK display are implemented in the driver. The trick to understanding this is that you have to understand the concept of how direct rendering works. With direct rendering there is no requirement to send everything to another process or the kernel. You can if you want, but you don't have to. --- Alan Cox <[EMAIL PROTECTED]> wrote: > On Maw, 2004-05-11 at 19:48, Egbert Eich wrote: > > For the text console to be usable you possibly want to be able to > > 1. move the fb start address for scrolling > > 2. to do some basik 2D accel for fast text drawing > > I thought about this a bit more.
