For DRI to work correctly there are several independent pieces that all have to be "in sync".
* XFree86 server which loads drm modules (via xfree86 driver module) * The drm kernel module * The agpgart kernel module Does anybody know for the proprietary drivers (supplied by ATI and Nvidia) which pieces they replace and which pieces they expect to be there? The reason I'm asking is to understand the consequences of changing an API. I'm curious to the answer in general, but in this specific instance the api I'm worried about is between the agpgart kernel module and drm kernel module. If the agpgart kernel module modifies it's API will that break things for someone who installs a proprietary 3D driver? Do the proprietary drivers limit themselves to mesa driver and retain the existing kernel services assuming the IOCTL's are the same? Or do they replace the kernel drm drivers as well? If so do they manage AGP themselves, or do they use the systems agpgart driver? Do they replace the systems agpgart driver? -- John Dennis <[EMAIL PROTECTED]> _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
