2018-12-28mm/mmu_notifier: use structure for invalidate_range_start/end callbackJérôme Glisse
Patch series "mmu notifier contextual informations", v2. This patchset adds contextual information, why an invalidation is happening, to mmu notifier callback. This is necessary for user of mmu notifier that wish to maintains their own data structure without having to add new fields to struct vm_area_struct (vma). For instance device can have they own page table that mirror the process address space. When a vma is unmap (munmap() syscall) the device driver can free the device page table for the range. Today we do not have any information on why a mmu notifier call back is happening and thus device driver have to assume that it is always an munmap(). This is inefficient at it means that it needs to re-allocate device page table on next page fault and rebuild the whole device driver data structure for the range. Other use case beside munmap() also exist, for instance it is pointless for device driver to invalidate the device page table when the invalidation is for the soft dirtyness tracking. Or device driver can optimize away mprotect() that change the page table permission access for the range. This patchset enables all this optimizations for device drivers. I do not include any of those in this series but another patchset I am posting will leverage this. The patchset is pretty simple from a code point of view. The first two patches consolidate all mmu notifier arguments into a struct so that it is easier to add/change arguments. The last patch adds the contextual information (munmap, protection, soft dirty, clear, ...). This patch (of 3): To avoid having to change many callback definition everytime we want to add a parameter use a structure to group all parameters for the mmu_notifier invalidate_range_start/end callback. No functional changes with this patch.

2018-12-28drm/i915/ringbuffer: Pull the render flush into breadcrumb emissionChris Wilson
In preparation for removing the manual EMIT_FLUSH prior to emitting the breadcrumb implement the flush inline with writing the breadcrumb for ringbuffer emission. With a combined flush+breadcrumb, we can use a single operation to both flush and after the flush is complete (post-sync) write the breadcrumb. This gives us a strongly ordered operation that should be sufficient to serialise the write before we emit the interrupt; and therefore we may take the opportunity to remove the irq_seqno_barrier w/a for gen6+. Although using the PIPECONTROL to write the breadcrumb is slower than MI_STORE_DWORD_IMM, by combining the operations into one and removing the extra flush (next patch) it is faster For gen2-5, we simply combine the MI_FLUSH into the breadcrumb emission, though maybe we could find a solution here to the seqno-vs-interrupt issue on Ironlake by mixing up the flush? The answer is no, adding an MI_FLUSH before the interrupt is insufficient.

2018-12-28drm/i915: Remove HW semaphores for gen7 inter-engine synchronisationChris Wilson
The writing is on the wall for the existence of a single execution queue along each engine, and as a consequence we will not be able to track dependencies along the HW queue itself, i.e. we will not be able to use HW semaphores on gen7 as they use a global set of registers (and unlike gen8+ we can not effectively target memory to keep per-context seqno and dependencies). On the positive side, when we implement request reordering for gen7 we also can not presume a simple execution queue and would also require removing the current semaphore generation code. So this bring us another step closer to request reordering for ringbuffer submission! The negative side is that using interrupts to drive inter-engine synchronisation is much slower (4us -> 15us to do a nop on each of the 3 engines on ivb). This is much better than it was at the time of introducing the HW semaphores and equally important userspace weaned itself off intermixing dependent BLT/RENDER operations (the prime culprit was glyph rendering in UXA). So while we regress the microbenchmarks, it should not impact the user.

2018-12-28drm/i915: Restrict PSMI context load w/a to Haswell GT1Chris Wilson
After we found a workaround for a hang on context load, Ben Widawsky found confirmation that it was for an issue with waking from rc6 and loading a context image. The workaround from on high suggests that we should I915_WRITE(RING_WAIT_FOR_RC6_EXIT(engine->mmio_base), _MASKED_FIELD(RING_RC6_SEL_WRITE_ADDR_MASK, RING_RC6_SEL_WRITE_ADDR_UPPER_LEFT)); in our rc6 setup for Haswell GT1, but on applying that we find instead that the machine encounters a GT forcewake error and locks up. As we are removing HW semaphore usage in the next patch, and the suggested workaround is no improvement, we need to decouple the PSMI workaround from HAS_SEMAPHORES to IS_HSW_GT1.

2018-12-25drm/i915: DDI: call intel_psr_ and _edp_drrs_enable() on pipe updates (v2)Hans de Goede
Call intel_psr_enable() and intel_edp_drrs_enable() on pipe updates to make sure that we enable PSR / DRRS (when applicable) on fastsets. Note calling these functions when PSR / DRRS has already been enabled is a no-op, so it is safe to do this on every encoder->update_pipe callback.

This is a preparation patch for ensuring that DRRS is enabled on fastsets.

fastsets (v2) When we are doing a fastset (needs_modeset=false, update_pipe=true) we may need to update some encoder-level things such as checking that PSR is enabled. This commit adds an update_pipe callback to intel_encoder and a new intel_encoders_update_pipe helper which calls this for all encoders connected to a crtc. The new intel_encoders_update_pipe helper is called from intel_update_crtc when doing a fastset.

In the case where state cannot be allocated, the current exit path via label 'out' will dereference the null state pointer when calling drm_atomic_state_put. Fix this by adding a new error exit label and jumping to this to avoid the drm_atomic_state_put.

2018-12-22drm/i915: Unwind failure on pinning the gen7 ppgttChris Wilson
If we fail to pin the ggtt vma slot for the ppgtt page tables, we need to unwind the locals before reporting the error. Or else on subsequent attempts to bind the page tables into the ggtt, we will already believe that the vma has been pinned and continue on blithely. If something else should happen to be at that location, choas ensues.

2018-12-22treewide: surround Kconfig file paths with double quotesMasahiro Yamada
The Kconfig lexer supports special characters such as '.' and '/' in the parameter context. In my understanding, the reason is just to support bare file paths in the source statement. I do not see a good reason to complicate Kconfig for the room of ambiguity. The majority of code already surrounds file paths with double quotes, and it makes sense since file paths are constant string literals. Make it treewide consistent now.
