Just a small bikeshed to consider. Having switched to
I915_PRIORITY_NORMAL, do we have a better name for default_priolist? I
still prefer default_priolist over normal_priolist. Go back to
I915_PRIORITY_DEFAULT?
default_priolist is fine I think since it is dual purpose. Primary
purpose to avoid allocations as you said.
Although I am still a bit dejected how some userspace could decide one
day to send everything at I915_PRIORITY_NORMAL - n, in order to use
I915_PRIORITY_NORMAL as the high prio not requiring cap_sys_admin, and
in doing so completely defeat the atomic kmalloc avoidance. :(
