-/* 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.
