X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e13af9a8340685cfe25d0c9f708da7121e0f51dd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git Merge tag 'drm-intel-next-2013-07-12' of git://people.freedesktop.org/~danvet/drm-intel into drm-next Highlights: - follow-up refactoring after the shared dpll rework that landed in 3.11 - oddball prep cleanups from Ben for ppgtt - encoder->get_config state tracking infrastructure from Jesse - used by the experimental fastboot support from Jesse (disabled by default) - make the error state file official and add it to our sysfs interface (Mika) - drm_mm prep changes from Ben, prepares to embedd the drm_mm_node (which will be used by the vma rework later on) - interrupt handling rework, follow up cleanups to the VECS enabling, hpd storm handling and fifo underrun reporting. - Big pile of smaller cleanups, code improvements and related stuff. * tag 'drm-intel-next-2013-07-12' of git://people.freedesktop.org/~danvet/drm-intel: (72 commits) drm/i915: clear DPLL reg when disabling i9xx dplls drm/i915: Fix up cpt pixel multiplier enable sequence drm/i915: clean up vlv ->pre_pll_enable and pll enable sequence drm/i915: move error state to own compilation unit drm/i915: Don't attempt to read an unitialized stack value drm/i915: Use for_each_pipe() when possible drm/i915: don't enable PM_VEBOX_CS_ERROR_INTERRUPT drm/i915: unify ring irq refcounts (again) drm/i915: kill dev_priv->rps.lock drm/i915: queue work outside spinlock in hsw_pm_irq_handler drm/i915: streamline hsw_pm_irq_handler drm/i915: irq handlers don't need interrupt-safe spinlocks drm/i915: kill lpt pch transcoder->crtc mapping code for fifo underruns drm/i915: improve GEN7_ERR_INT clearing for fifo underrun reporting drm/i915: improve SERR_INT clearing for fifo underrun reporting drm/i915: extract ibx_display_interrupt_update drm/i915: remove unused members from drm_i915_private drm/i915: don't frob mm.suspended when not using ums drm/i915: Fix VLV DP RBR/HDMI/DAC PLL LPF coefficients drm/i915: WARN if the bios reserved range is bigger than stolen size ...
