Hi, gonzo@ committed a fix (r278615) to the videocore driver for the raspberry pi. The fix involved doing an explicit wire of pages that were about to be passed down to the hardware to send to the videobuffer hardware.
It turns out that doing vm_fault_quick_hold_pages() wasn't enough - the pages weren't being wired, and they may disappear before the hardware gets to them. I looked at vmapbuf() and how it uses vm_fault_quick_hold_pages(), but I can't find anything that wires the pages down before it hands the addresses to the hardware. So, am I missing something about how/where that's done?
