/* Idling in the depth/stencil span functions:
* For writes, the kernel reads from the given user-space buffer at dispatch
* time, and then writes to the depth buffer asynchronously.
* For reads, the kernel reads from the depth buffer and writes to the span
* temporary asynchronously.
* So, if we're going to read from the span temporary, we need to idle before
* doing so. But we don't need to idle after write, because the CPU won't
* be accessing the destination, only the accelerator (through 3d rendering or
* depth span reads)
* However, due to interactions from pixel cache between 2d (what we do with
* depth) and 3d (all other parts of the system), we idle at the begin and end
* of a set of span operations, which should cover the pix cache issue.
* Except, we still have major issues, as shown by no_rast=true glxgears, or
* stencilwrap.
