we are working on putting the emulator into linuxbios as an optional component. Once this is done, I think the prognosis is good. We've gotten distracted by fixing other things needed to support the emulator.
What will be needed to run video on non-x86? The oem videoBIOS plus an 8086 emulator for when videoBIOS calls are made?
For hardware that is not on a plugin card it will likely be an ATI Rage XL
or a simlar low end chip and we can get the docs to initialize it. YhLu
and Stefan have already accomplished that for the ATI Rage XL, and that linuxbios
driver should have no arch dependencies.
For a plugin card we need to run the boot rom just to initialize the card. After that all of the standard Linux code should work.
We design all our own boards and have the access to the graphics processor data as well as the vendors videoBIOS.
For x86 it's easy for us. We get oem drivers and the tools to modify the oem videoBIOS.
For non-x86 such as ARM the GPU developers (who make the silicon) don't have answers since they only work in the x86 world or a very small fraction know PPC for Apple or IBM.
ATI and nVidia don't let source out for the most current parts. There is some xFree86 driver source for the 3-4 year old devices. For ATI there may be source for up the Radeon 9000. That source is what were looking at to get PC GPU's working on ARM with ARMLinux.
