DetailsI've discovered that, while DRI works from the start with the "via" driver in Xorg 7, I cannot enable AGP DMA. Putting
Option "EnableAGPDMA" "true" in xorg.conf results in this error message: (EE) VIA(0): [drm] drmAgpAcquire failed 1023 (EE) VIA(0): [drm] Failed to initialize DMA ring-buffer: 1005 Xorg still starts, and DRI still works fine, but AGP DMA is not enabled. This is not a major issue; however, using AGP DMA significantly improves OpenGL performance, so failing to use it is not desirable. Also... Can someone confirm this for a driver other than "via"? Does the same error occure with Savage or i810 graphics? |

(**) VIA(0): Option "EnableAGPDMA"
(**) VIA(0): Option: EnableAGPDMA - Enabling AGP DMA
And glxgears gives me 120 more FPS than it did before.
It appears that what solved the problem was removing GLCore from the list of Xorg modules to load. Why this should be, I don't know - I removed it from the list because it apparently doesn't exist as a separate module in Xorg 7, judging from what Xorg's log was saying.
It's back after the latest upgrade:
