* Not all clients may want to attempt automatic recover of a context after
* a hang (for example, some clients may only submit very small incremental
* batches relying on known logical state of previous batches which will never
* recover correctly and each attempt will hang), and so would prefer that
* the context is forever banned instead.
*
* If set to false (0), after a reset, subsequent (and in flight) rendering
* from this context is discarded, and the client will need to create a new
* context to use instead.
*
* If set to true (1), the kernel will automatically attempt to recover the
* context by skipping the hanging batch and executing the next batch starting
* from the default context state (discarding the incomplete logical context
* state lost due to the reset).
*
* On creation, all new contexts are marked as recoverable.
