| * | | | drm/exynos: consider buffer allocation without iommuInki Dae2013-01-04

Without iommu, dma_alloc_attrs function allocates some memory region and returns cpu address so this patch makes the cpu address to be set to buf->kvaddr correctly. Changelog v2: - fix buffer free .

Based on Chris' fix for SNA, now also for UXA/mesa&old SNA. - Some more fixlets for shrinker-pulls-the-rug issues (Chris&me). - Fix dma-buf flags when exporting (you). - Disable the VGA plane if it's enabled on lid open - similar fix in spirit to the one I've sent you last weeek, BIOS' really like to mess with the display when closing the lid (awesome debug work from Krzysztof Mazur). * 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel: drm/i915: disable shrinker lock stealing for create_mmap_offset drm/i915: optionally disable shrinker lock stealing drm/i915: fix flags in dma buf exporting i915: ensure that VGA plane is disabled drm/i915: Preallocate the drm_mm_node prior to manipulating the GTT drm_mm manager drm: Export routines for inserting preallocated nodes into the mm manager drm/i915: don't disable disconnected outputs drm/i915: Implement workaround for broken CS tlb on i830/845 drm/i915: Implement WaSetupGtModeTdRowDispatch drm/i915: Implement WaDisableHiZPlanesWhenMSAAEnabled drm/i915: Prefer CRTC 'active' rather than 'enabled' during WM computations drm/i915: Clear self-refresh watermarks when disabled drm/i915: Double the cursor self-refresh latency on Valleyview drm/i915: Fixup cursor latency used for IVB lp3 watermarks
| * | drm/i915: disable shrinker lock stealing for create_mmap_offsetDaniel Vetter2012-12-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mmap offset structure is not part of the drm/i915 code, but provided by gem helpers. To avoid leaky abstractions (by either depending upon implementation details of said helper wrt to preallocations, or reimplementing it in our code and so fuzzing around in internal details of that helpr) simply disable the shrinker lock stealing accross calls into the helper functions. This should fix igt/gem_tiled_swapping. v2: Fix cleanup path confusion bemoaned by Chris Wilson.

But this also caused the requirement that every place which allocates memory needs to be careful about the gem state of objects, since the shrinker could have pulled the rug out from under it. We've usually solved this by carefully preallocating things or ensure that buffers are pinned already. But the shrinker also reaps mmap offset, so allocating those needs to be careful, too. Now that code has been factored out into some common helpers, so either we have fragile code depending upon the common helper not doing something we don't want it to do. Or we need to reimplement the mmap offset creation and so also leak implementation details into our code. Since this all results in leaky abstraction, cop out by disabling the lock borrowing trick while calling down into the helpers. That way our craziness is nicely confined to files in drm/i915. v2: Split out the change to create_mmap_offset as request by Chris Wilson.
