Merge tag 'drm-intel-next-2019-10-07' of git://anongit.freedesktop.org/drm/drm-intel into drm-next
UAPI Changes:
- Never allow userptr into the mappable GGTT (Chris)
No existing users. Avoid anyone from even trying to
spare a deadlock scenario.
Cross-subsystem Changes:
Core Changes:
Driver Changes:
- Eliminate struct_mutex use as BKL! (Chris)
Only used for execbuf serialisation.
- Initialize DDI TC and TBT ports (D-I) on Tigerlake (Lucas)
- Fix DKL link training for 2.7GHz and 1.62GHz (Jose)
- Add Tigerlake DKL PHY programming sequences (Clinton)
- Add Tigerlake Thunderbolt PLL divider values (Imre)
- drm/i915: Use helpers for drm_mm_node booleans (Chris)
- Restrict L3 remapping sysfs interface to dwords (Chris)
- Fix audio power up sequence for gen10+ display (Kai)
- Skip redundant execlist resubmission (Chris)
- Only unwedge if we can reset GPU first (Chris)
- Initialise breadcrumb lists on the virtual engine (Chris)
- Don't rely on kernel context existing during early errors (Matt A)
- Update Icelake+ MG_DP_MODE programming table (Clinton)
- Update DMC firmware for Icelake (Anusha)
- Downgrade DP MST error after unplugging TypeC cable (Srinivasan)
- Limit MST modes based on plane size too (Ville)
- Polish intel_tv_mode_valid() (Ville)
- Fix g4x sprite scaling stride check with GTT remapping (Ville)
- Don't advertize non-exisiting crtcs (Ville)
- Clean up encoder->crtc_mask setup (Ville)
- Use tc_port instead of port parameter to MG registers (Jose)
- Remove static variable for aux last status (Jani)
- Implement a better i945gm vblank irq vs. C-states workaround (Ville)
- Make the object creation interface consistent (CQ)
- Rename intel_vga_msr_write() to intel_vga_reset_io_mem() (Jani, Ville)
- Eliminate previous drm_dbg/drm_err usage (Jani)
- Move gmbus setup down to intel_modeset_init() (Jani)
- Abstract all vgaarb access to intel_vga.[ch] (Jani)
- Split out i915_switcheroo.[ch] from i915_drv.c (Jani)
- Use intel_gt in has_reset* (Chris)
