Merge branch 'linux-3.17' of git://anongit.freedesktop.org/git/nouveau/linux-2.6
Pull nouveau drm updates from Ben Skeggs: "Apologies for not getting this done in time for Dave's drm-next merge window. As he mentioned, a pre-existing bug reared its head a lot more obviously after this lot of changes. It took quite a bit of time to track it down. In any case, Dave suggested I try my luck by sending directly to you this time. Overview: - more code for Tegra GK20A from NVIDIA - probing, reclockig - better fix for Kepler GPUs that have the graphics engine powered off on startup, method courtesy of info provided by NVIDIA - unhardcoding of a bunch of graphics engine setup on Fermi/Kepler/Maxwell, will hopefully solve some issues people have noticed on higher-end models - support for "Zero Bandwidth Clear" on Fermi/Kepler/Maxwell, needs userspace support in general, but some lucky apps will benefit automagically - reviewed/exposed the full object APIs to userspace (finally), gives it access to perfctrs, ZBC controls, various events. More to come in the future. - various other fixes" Acked-by: Dave Airlie <airlied@redhat.com> * 'linux-3.17' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (87 commits) drm/nouveau: expose the full object/event interfaces to userspace drm/nouveau: fix headless mode drm/nouveau: hide sysfs pstate file behind an option again drm/nv50/disp: shhh compiler drm/gf100-/gr: implement the proper SetShaderExceptions method drm/gf100-/gr: remove some broken ltc bashing, for now drm/gf100-/gr: unhardcode attribute cb config drm/gf100-/gr: fetch tpcs-per-ppc info on startup drm/gf100-/gr: unhardcode pagepool config drm/gf100-/gr: unhardcode bundle cb config drm/gf100-/gr: improve initial context patch list helpers drm/gf100-/gr: add support for zero bandwidth clear drm/nouveau/ltc: add zbc drivers drm/nouveau/ltc: s/ltcg/ltc/ + cleanup drm/nouveau: use ram info from nvif_device drm/nouveau/disp: implement nvif event sources for vblank/connector notifiers drm/nouveau/disp: allow user direct access to channel control registers drm/nouveau/disp: audit and version display classes drm/nouveau/disp: audit and version SCANOUTPOS method drm/nv50-/disp: audit and version PIOR_PWR method ...
