But I've moved all the feature-y stuff to -next, so this really is all -fixes. Most of it is handling fallout from the hw context stuff, discovered now that mesa git has started using them for real. Otherwise all just small fixes: - unbreak modeset=0 on gen6+ (regressed in next) - const mismatch fix for ->mode_fixup - simplify overly clever lvds modeset code (current code can totally confuse backlights, resulting in broken panels until a full power draw restores them). - fix some fallout from the flushing_list disabling (regression only introduced in -next) - DP link train improvements (this also kills the last 3.2 dp regression afaik) - bugfix for the new ddc VGA detection on newer platforms - minor backlight fixes (one of them a -next regression) - only enable the required PM interrupts (to avoid waking up the cpu unnecessarily) - some really minor bits (workaround clarification, make coverty happy, hsw init fix) * 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel: (23 commits) drm/i915: unbreak lastclose for failed driver init drm/i915: Set the context before setting up regs for the context. drm/i915: constify mode in crtc_mode_fixup drm/i915/lvds: ditch ->prepare special case drm/i915: dereferencing an error pointer drm/i915: fix invalid reference handling of the default ctx obj drm/i915: Add -EIO to the list of known errors for __wait_seqno drm/i915: Flush the context object from the CPU caches upon switching drm/i915: Make the lock for pageflips interruptible drm/i915: don't forget the PCH backlight registers drm/i915: Insert a flush between batches if the breadcrumb was dropped drm/i915: missing error case in init status page drm/i915: mask tiled bit when updating ILK sprites drm/i915: try to train DP even harder drm/i915: kill intel_ddc_probe drm/i915: check whether we actually received an edid in detect_ddc drm/i915: fix up PCH backlight #define mixup drm/i915: Add comments to explain the BSD tail write workaround drm/i915: Disable the BLT on pre-production SNB hardware drm/i915: initialize power wells in modeset_init_hw ... --- 98c7b42375011ec37251e6fc85a0471cfe499eea diff --cc drivers/gpu/drm/i915/intel_display.c index bc25a24a08c,e9e476eca89..f6159765f1e --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@@ -7172,8 -7175,26 +7175,13 @@@ static void i915_disable_vga(struct drm POSTING_READ(vga_reg); } -static void ivb_pch_pwm_override(struct drm_device *dev) -{ - struct drm_i915_private *dev_priv = dev->dev_private; - - /* - * IVB has CPU eDP backlight regs too, set things up to let the - * PCH regs control the backlight - */ - I915_WRITE(BLC_PWM_CPU_CTL2, BLM_PWM_ENABLE); - I915_WRITE(BLC_PWM_CPU_CTL, 0); - I915_WRITE(BLC_PWM_PCH_CTL1, BLM_PCH_PWM_ENABLE | BLM_PCH_OVERRIDE_ENABLE); -} - void intel_modeset_init_hw(struct drm_device *dev) { + /* We attempt to init the necessary power wells early in the initialization + * time, so the subsystems that expect power to be enabled can work. + */ + intel_init_power_wells(dev); + intel_prepare_ddi(dev); intel_init_clock_gating(dev);
