I've asked the driver author if the calls to vm_page_wire() and
vm_page_unwire() can simply be removed but have not heard back yet.
Is there any news on this? I have updated to the latest current so I'm
running the nv driver now, but I'd like to get the nvidia driver running
again.
Yes, the unnecessary (and now problematic) wiring and unwiring calls will
be
removed in a future release of the driver.
Excellent! Any ETA? Or are there patches against an existing version of
the driver?
I would just remove the calls to vm_page_wire() and vm_page_unwire() along
with the immediately adjacent calls to vm_page_{un,}lock_queues().
Just to confirm, like the attached patch?
Yes.
This is with a GeForce GT 240M, current/amd64 r209035, nvidia-driver
195.36.15
I haven't runtime-tested it yet...
