[Mesa-dev] [PATCH 02/10] mesa: Add dd_function_table::GetGraphicsResetStatus

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

This allows drivers to determine whether a GPU reset has occured.  It
should return non-zero status if a reset was observed by the specified
context.  Another mechanism will be used to observe resets occuring in
other contexts in the share group.
