Two "updated" patches, according to Michel Daenzers review. See separate e-mail for details. 01/10: Replaces original 01/09 -- Same code, updated commit message. 10/10: Just for demonstration, not for application to ddx.

Hi, here a set of patches against the nouveau-ddx. This is an extended and revised set, based on Francisco Jerez feedback from autumn last year. [1/9] Makes pageflipping work again on X-Server 1.12rc. It apparently stopped working somewhere around Xorg 1.11+. [2/9] Implements handling of pageflip completion events from the kernel. Francisco Jerez argument against including it was that the

Hi all, the following patch fixes a race-condition in the nouveau ddx which caused frequent x-server crashes for at least 1 user under some loads when OpenGL triple-buffering is enabled, which it is by default on XOrg 1.12 and later. As a side effect, it provides a small optimization for the common case of bufferswap at next vblank. The other way to avoid the race + possible crash is to set
