* Re-submitting jobs was a concept AMD came up as cheap way to implement

* recovery after a job timeout.
|
||||
*
|
||||
* This turned out to be not working very well. First of all there are many
|
||||
* problem with the dma_fence implementation and requirements. Either the
|
||||
* implementation is risking deadlocks with core memory management or violating
|
||||
* documented implementation details of the dma_fence object.
|
||||
*
|
||||
* Drivers can still save and restore their state for recovery operations, but
|
||||
* we shouldn't make this a general scheduler feature around the dma_fence
|
||||
* interface.
