2017-02-15drm/i915: Micro-optimise gen8_ppgtt_insert_entries()Chris Wilson
Improve the sg iteration and in hte process eliminate a bug in miscomputing the pml4 length as orig_nents<<PAGE_SHIFT is no longer the full length of the sg table. v2: Check for the end of the fourth level page table (the final pdpe) and move onto the next. v3: Assert that 3lvl insert_pte_entries doesn't overflow its smaller set of PDP.

2017-02-15drm/i915: Micro-optimise gen6_ppgtt_insert_entries()Chris Wilson
Inline the address computation to avoid the vfunc call for every page. We still have to pay the high overhead of sg_page_iter_next(), but now at least GCC can optimise the inner most loop, giving a significant boost to some thrashing Unreal Engine workloads.

2017-02-15drm/i915: Fix not finding the VBT when it overlaps with OPREGION_ASLE_EXTHans de Goede
If there is no OPREGION_ASLE_EXT then a VBT stored in mailbox #4 may use the ASLE_EXT parts of the opregion. Adjust the vbt_size calculation for a vbt in mailbox #4 for this. This fixes the driver not finding the VBT on a jumper ezpad mini3 cherrytrail tablet and on a ACER SW5_017 machine.

2017-02-15drm/rockchip: Use common IOMMU API to attach devicesShunqian Zheng
Rockchip DRM used the arm special API, arm_iommu_*(), to attach iommu for ARM32 SoCs. This patch convert to common iommu API so it would support ARM64 like RK3399. Since previous patch added support for direct IOMMU address space management, there is no need to use DMA API anymore and this patch wires things to use the new method.

2017-02-15drm/rockchip: Do not use DMA mapping API if attached to IOMMU domainTomasz Figa
The API is not suitable for subsystems consisting of multiple devices and requires severe hacks to use it. To mitigate this, this patch implements allocation and address space management locally by using helpers provided by DRM framework, like other DRM drivers do, e.g. Tegra. This patch should not introduce any functional changes until the driver is made to attach subdevices into an IOMMU domain with the generic IOMMU API, which will happen in following patch. Based heavily on GEM implementation of Tegra DRM driver.

2017-02-14drm/i915: Only apply the jump to the "efficient RPS" frequency on startupChris Wilson
Currently we apply the jump to rpe if we are below it and the GPU needs more power. For some GPUs, the rpe is 75% of the maximum range causing us to dramatically overshoot low power applications *and* unable to reach the low frequency that can most efficiently deliver their workload.

2017-02-14drm/i915: Enable fine-tuned RPS for cherryviewChris Wilson
When the RPS tuning was applied to Baytrail, in commit 8fb55197e64d ("drm/i915: Agressive downclocking on Baytrail"), concern was given that it might cause Cherryview excess wakeups of the common power well. However, the static thresholds perform poorly for Kodi, and the GPU is unable to deliver the video frames on time. Enabling the dynamic, finer thresholds used on all other platforms (including Skylake and Broxton that also have the same multiple powerwell concerns) allows the GPU to pick a more appropriate frequency and not drop frames.

2017-02-14drm/i915: The return of i915_gpu_info to debugfsChris Wilson
Once upon a time before we had automated GPU state capture upon hangs, we had intel_gpu_dump. Now we come almost full circle and reinstate that view of the current GPU queues and registers by using the error capture facility to snapshot the GPU state when debugfs/.../i915_gpu_info is opened - which should provided useful debugging to both the error capture routines (without having to cause a hang and avoid the error state being eaten by igt) and generally. v2: Rename drm_i915_error_state to i915_gpu_state to alleviate some name collisions between the error state dump and inspecting the gpu state.

2017-02-14drm/i915: Emit to ringbuffer directlyTvrtko Ursulin
This removes the usage of intel_ring_emit in favour of directly writing to the ring buffer. intel_ring_emit was preventing the compiler for optimising fetch and increment of the current ring buffer pointer and therefore generating very verbose code for every write. It had no useful purpose since all ringbuffer operations are started and ended with intel_ring_begin and intel_ring_advance respectively, with no bail out in the middle possible, so it is fine to increment the tail in intel_ring_begin and let the code manage the pointer itself. Useless instruction removal amounts to approximately two and half kilobytes of saved text on my build. Not sure if this has any measurable performance implications but executing a ton of useless instructions on fast paths cannot be good. v2: * Change return from intel_ring_begin to error pointer by popular demand. * Move tail increment to intel_ring_advance to enable some error checking. v3: * Move tail advance back into intel_ring_begin. * Rebase and tidy. v4: * Complete rebase after a few months since v3. v5: * Remove unecessary cast and fix !debug compile. (Chris Wilson) v6: * Make intel_ring_offset take request as well. * Fix recording of request postfix plus a sprinkle of asserts. (Chris Wilson) v7: * Use intel_ring_offset to get the postfix.

2017-02-13drm/i915: Use fault-injection to force the shrinker to run in live GTT testsChris Wilson
It is possible whilst allocating the page-directory tree for a ppgtt bind that the shrinker may run and reap unused parts of the tree. If the shrinker happens to remove a chunk of the tree that the allocate_va_range has already processed, we may then try to insert into the dangling tree. This test uses the fault-injection framework to force the shrinker to be invoked before we allocate new pages, i.e. new chunks of the PD tree.
