Hi,
I've managed to implement double buffering with new, unofficial radeon drivers(kindly provided by Didier) under XBIOS(not VDI). Here's some details with full source code:
http://nokturnal.pl/2011/03/ati_radeon_xbios_doublebufferin
CMD_TEXTUREMEM should be reimplemented I think. I mean texture should be loaded by one function to video memory only once, and tiled in destination buffer by another function (like this is made with OpenGL - once loaded in VRAM, texture is referenced via integer handle and can be tiled on destination surface in different ways).
I would also like to see more hardware accelerated functions for basic primitives and batch loading them(arrays of primitives) in one go to Radeon memory. I've tried to draw one line in 640x480@32 bit from 0,0 to 639,479 with CMD_FILLMEM(width and height 1x1 to produce pixel) and it ended in slide show. And at this moment there is no other way set individual pixel ;). Maybe besides accessing VRAM through local bus which is slow atm.
But block operations(copying/filling VRAM->VRAM) are really fast. It's plain to see in block filling and horizontal line drawing.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
