I finally tracked down the last remaining major bug in the mach64 Mesa 4.x branch. The secondary texture filter wasn't being set in the correct register (was being set in scale_3d_cntl not tex_cntl), so it ended up enabling fog instead, which disables alpha blending! This was actually in the last branch too, so I'm not sure why this hadn't cropped up before (maybe I changed my quake settings and didn't remeber?). At any rate, the branch should now be at about the same state the previous branch was in. There are still some bugs remaining, and I plan on running glean and maybe some other test suites on the new branch as well. This would be a good time for testers to do a fresh checkout and look for bugs. When the trunk has stabilized, we can merge in any Mesa bugfixes too.
So I think we can try to focus on the DMA work now. Frank, can you check in whatever you've got into the -dma branch? It doesn't matter if it's not done, I think it would be helpful for us to see where we stand now. One thing I want to try is using NOTEX or TINY vertices as well as textured verticies. It seems that mach64 ought to be able to handle those since spec_argb, z, argb, and x_y are sequential registers, and it could pump up our gears numbers a bit. ;) I'll see if I can get it to work with MMIO and if so, we could try those vertex formats with DMA as well. -- Leif Delgass http://www.retinalburn.net _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
