On gen5+ a HW context consists of an + * opaque GPU object which is referenced at times of context saves and restores. + * With RC6 enabled, the context is also referenced as the GPU enters and exists + * from RC6 (GPU has it's own internal power context, except on gen5). Though + * something like a context does exist for the media ring, the code only + * supports contexts for the render ring. + * + * In software, there is a distinction between contexts created by the user, + * and the default HW context. The default HW context is used by GPU clients + * that do not request setup of their own hardware context. The default + * context's state is never restored to help prevent programming errors. This + * would happen if a client ran and piggy-backed off another clients GPU state. + * The default context only exists to give the GPU some offset to load as the + * current to invoke a save of the context we actually care about. In fact, the + * code could likely be constructed, albeit in a more complicated fashion, to + * never use the default context, though that limits the driver's ability to + * swap out, and/or destroy other contexts. + * + * All other contexts are created as a request by the GPU client. These contexts + * store GPU state, and thus allow GPU clients to not re-emit state (and + * potentially query certain state) at any time. The kernel driver makes + * certain that the appropriate commands are inserted. + * + * The context life cycle is semi-complicated in that context BOs may live + * longer than the context itself because of the way the hardware, and object + * tracking works.

The GPU has loaded it's state already and has stored away the gtt + * offset of the BO. The GPU is not actively referencing the data at this + * offset, but it will on the next context switch. The only way to avoid this + * is to do a GPU reset. + * + * An "active context' is one which was previously the "current context" and is + * on the active list waiting for the next context switch to occur. Until this + * happens, the object must remain at the same gtt offset.
