One more question. Why must so much memory be reserved at the X server startup? Can it be allocated at run time instead?

FYI, I checked in this code so the depth buffer at 24-bit depth is now only allocated as 16-bit and the difference is used for textures. Of course renderering is still pretty slow at 24-bit depth compared to 16-bit. -- Leif Delgass http://www.retinalburn.net ___ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
Re: [Dri-devel] mach64: How much video memory is needed?
Actually, Leif is right. DRI really works on 1024x768 but... very slow (thanks to PIO?). My Rage Mobility cannot run Counter-Strike properly (the game is unplayable in this mode). In 800x600 it is quite OK.

I have an 8MB card, and I run the X server at 1024x768 @ 16-bit depth or 800x600 @ 24-bit depth. You need enough memory for 3 times the virtual screen size at the given depth (front, back, and depth buffers), plus textures and pixmap cache. The depth buffer is always 16-bit, so at 24-bit depth (32bpp framebuffer) it's smaller than the front and back buffers, but the current branch allocates enough for a 32bpp depth buffer. I have code to fix that, but I need to clean it up before checking it in. -- Leif Delgass http://www.retinalburn.net ___ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel

Today, Mach64 DRI driver does not use GART so it cannot use system memory and we are restricted by the amount of video memory. The team first is going to enable DMA, then - GART (at least I was told so some time ago). So just wait and see...

I'm now trying mach64-0-0-4-branch with Rage Mobility-M PCI (LR). The compiled X server does not work in a setting more than 800x600 16bpp. How much video memory is needed to use Mach64 DRI in general? -- "Free software is not for free."
