Ok so i reread stuff and the : drm/radeon: add general purpose fence signaled callback is a big NAK actually. It change the paradigm. Moving most of the handling into the irq process which is something i am intimatly convinced we should avoid.
Here is the patchset up to ib pool cleanup. I have yet rebase the other patches as i am tracking done some issue in the sa allocation.

Before i forget, the big issue with doing work from irq handler is that we never know in middle of what other part can be. I believe it's lot better to have irq process only update fence (signaled/not signaled). and have the actual work happening on behalf of the process wether through sa alloc path or ttm path.
