Just now I am adding more accelerator classs to LNVRM then the fun of linking them into X I say my LNVRM is already up and running allocating classs and free them and controlling the chip and DMA mappings and interrupts my X client is already using NV04_REANDER_SOLID_RECTANGLE thou DMA channel I also have made my own software class NV04_NVXF_DISPLAY in steed of NV04_VIDEO_LUT_CURSOR_DAC For controlling the screen > On Tue, 25 Mar 2003, dave wrote: > > > Help I am writing a X-4.2.x fully accelerator driver > > For NVIDIA video cards . > > > > It consisted of 2 parts > > 1. kernel LNVRM (LINUX NVIDIA RESOURCE MANAGER) > > 2.
