OML extensions

Finally sat down with Mario to review his patches and ideas for making our OML sync implementation more accurate. He needs very accurate time stamping for his applications, and needs it in every configuration. He’s implemented patches to the DRM core, radeon and intel drivers to dramatically increase the accuracy and precision of our vblank timestamps. And we discussed a way to get accurate timestamps and necessary information for buffer swaps implemented with a blit. In short, we plan to have the kernel generate an event when a swap blit completes, and include info on the current scanline and all the usual timestamp fields. Hopefully Mario will find some time to post his series to dri-devel in the next few weeks so we can get it some wider exposure.


Had a nice night out yesterday (and this morning!) with various XDS attendees. Details omitted to shield the guilty, suffice it to say we met some real characters and had a lot of fun. Hope to go out to a nice restaurant tonight before flying back home tomorrow morning (will be nice to get some sleep finally on the plane, this has been a busy and mostly sleepless conference!).
