Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"One of the smaller drm -next pulls in ages!
Ben (nouveau) has a rewrite in progress but we decided to leave it
stew for another cycle, so just some fixes from him.
- radeon: lots of documentation work, fixes, more ring and locking
changes, pcie gen2, more dp fixes.
- i915: haswell features, gpu reset fixes, /dev/agpgart removal on
machines that we never used it on, more VGA/HDP fix., more DP fixes
- drm core: cleanups from Daniel, sis 64-bit fixes, range allocator
colouring.
but yeah fairly quiet merge this time, probably because I missed half
of it!"
Trivial add-add conflict in include/linux/pci_regs.h

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.
