CHANGES
=======
991208:
- installation bug: /dev/graphic needs to have minor 17 in order for
the demos to work with the setup described below!
- added TODO section in README.install
- PERMEDIA-meta driver handles IRQs now
- first version of a fully featured accelerator implementation
for the PERMEDIA chipset family. However, this needs some minor
fixes and improvements before it can be tested but should give
an idea how the driver side of acceleration may look like.
- the two points above made changes of the mode_set() functions
neccessary. In order to have understandable function names,
mode_setup() in the driver API has been renamed to mode_enter()
and the newly introduced function is mode_leave(). Better we
change a handful drivers now.
- debugged accelerator mapping code. Ping-pong buffers work with
a primitive debugging accelerator now.
- fixed bug 13) (pci arguments required, otherwise pagefault of
insmod)
- null displays (CONFIG_KGI_DPY_NULL) added. If you enable this
feature, KGI will register dummy display drivers at boot so that
open() on /dev/tty will not fail. This is only useful if you
want to use KGI's multihead capabilities with XFree86:
Plug in two keyboards and enable null displays. Then
start the first server on the first display using VT /dev/tty7
(e.g. you can do this via XDM) and the second server on the second
display using VT /dev/tty17 (via XDM).
TODO:
=====
I will address the problems below in the order they are mentioned.
However, if you spot an area where you think you may help, please
don't hesitate to contribute (the /dev/vcs emulator might be a
project to start)
- merge patches sent by Jon M. Taylor
- enable Permedia2 accelerator
- solve issue of drivers using wait-queues
- test virtualization of Permedia2 accelerator
like the test-{master/slave} demos
- accelerator performance tests
- make Permedia driver load as boot display substitute
- libGGI/XGGI port
- /dev/vcs emulator implementation
