Not something reliable enough to use in a shipping product, apparently.

- o11c 2y agoI imagine that a GPU-only "select this buffer when the next frame happens" would be better supported, even if the CPU doesn't get told when. Or even if you can't get an interrupt, you could poll periodically, etc.
- rep_lodsb 2y agoThat's already how it works on the VGA, you write the start address into a CRTC register and it will be used once the next frame starts, without affecting the current one.
