Re: What is DirectFB?

"95% of the users don't need and/or don't use that feature, why should the other 5% dictate those users what they should use and make them use software that's suffering from bitrot?"
1) 95% of users don't need and/or don't use KDE, but some version of Windows instead. Maybe we should just kill off the KDE project and all use Windows.
2) 95% of the time I drive, there are only one or two occupants in the automobile, which is a complete waste of the back seat. 95% of the time I drive, the trunk is empty, which is a complete waste of space. I would be much more efficient if I drove a motorcycle instead. Of course, it would then be damned inconvenient when I have more than one extra passenger, damned inconvenient when I need to go shopping for something that won't strap on the back, and damned invconvenient when I get a flat tire and realize that all my emergency tools were in the trunk of the car I sold because it was such a waste.
3) Perhaps 95% of Linux users don't need network transparency, but I will safely assert that 25% to 50% of UNIX users indeed use it on a regular basis. Maybe your vision of vision of a workstation is to be some sort of Xbox clone, used in the home by a single user to play games. But most of us use workstations in a multiuser networked environment to get our work done. A workstation without network transparency would make that work a heck of a lot harder to get done.
4) XFree86 is not suffering from bitrot. More people use network transparency than use Xinerama. But I don't see any hue and cry to get rid of Xinerama (or other multihead support).
5) A million people have already said this, but you haven't been listening. It seems you're attention has been wavering. So get this through your head, NETWORK TRANSPARENCY DOESN'T COST YOU ANYTHING IF YOU DON'T USE IT! |

Actually, network transparency DOES cost because it still has to pass through X's network layer. If you're running on a local machine, it doesn't cost *as much* as X over IP over ethernet, but calls to the X libraries still have to be converted to the X protocol, and passed though the network layer, transmitted over a Unix socket, recieved by the X server, and decoded.
There must be a simpler way of doing this.

You always need some protocol between the applications and the process/drivers that is responsible for drawing, unless you want to give the applications direct access to the graphics hardware. And even if they had direct access you would need some protocol for locking (because affordable hardware doesn't allow more than one driver to use it at a time).
There are, of course, different ways to implement this protocol. You can pass messages over unix domain sockets, which is the fastest IPC mechanism for messages on Linux, and what X11 does. Or you can put the driver into the kernel and define a few dozens ioctls. They are just another form of protocol. But whatever you do, you need some protocol.
