Merge tag 'drm-intel-next-2017-08-18' of git://anongit.freedesktop.org/git/drm-intel into drm-next
Final pile of features for 4.14 - New ioctl to change NOA configurations, plus prep (Lionel) - CCS (color compression) scanout support, based on the fancy new modifier additions (Ville&Ben) - Document i915 register macro style (Jani) - Many more gen10/cnl patches (Rodrigo, Pualo, ...) - More gpu reset vs. modeset duct-tape to restore the old way. - prep work for cnl: hpd_pin reorg (Rodrigo), support for more power wells (Imre), i2c pin reorg (Anusha) - drm_syncobj support (Jason Ekstrand) - forcewake vs gpu reset fix (Chris) - execbuf speedup for the no-relocs fastpath, anv/vk low-overhead ftw (Chris) - switch to idr/radixtree instead of the resizing ht for execbuf id->vma lookups (Chris) gvt: - MMIO save/restore optimization (Changbin) - Split workload scan vs. dispatch for more parallel exec (Ping) - vGPU full 48bit ppgtt support (Joonas, Tina) - vGPU hw id expose for perf (Zhenyu) Bunch of work all over to make the igt CI runs more complete/stable. Watch https://intel-gfx-ci.01.org/tree/drm-tip/shards-all.html for progress in getting this ready. Next week we're going into production mode (i.e. will send results to intel-gfx) on hsw, more platforms to come. Also, a new maintainer tram, I'm stepping out. Huge thanks to Jani for being an awesome co-maintainer the past few years, and all the best for Jani, Joonas&Rodrigo as the new maintainers! * tag 'drm-intel-next-2017-08-18' of git://anongit.freedesktop.org/git/drm-intel: (179 commits) drm/i915: Update DRIVER_DATE to 20170818 drm/i915/bxt: use NULL for GPIO connection ID drm/i915: Mark the GT as busy before idling the previous request drm/i915: Trivial grammar fix s/opt of/opt out of/ in comment drm/i915: Replace execbuf vma ht with an idr drm/i915: Simplify eb_lookup_vmas() drm/i915: Convert execbuf to use struct-of-array packing for critical fields drm/i915: Check context status before looking up our obj/vma drm/i915: Don't use MI_STORE_DWORD_IMM on Sandybridge/vcs drm/i915: Stop touching forcewake following a gen6+ engine reset MAINTAINERS: drm/i915 has a new maintainer team drm/i915: Split pin mapping into per platform functions drm/i915/opregion: let user specify override VBT via firmware load drm/i915/cnl: Reuse skl_wm_get_hw_state on Cannonlake. drm/i915/gen10: implement gen 10 watermarks calculations drm/i915/cnl: Fix LSPCON support. drm/i915/vbt: ignore extraneous child devices for a port drm/i915/cnl: Setup PAT Index. drm/i915/edp: Allow alternate fixed mode for eDP if available. drm/i915: Add support for drm syncobjs ...
