In the extreme case, we may wish to wait on an rcu-barrier to reap stale vm to purge the last of the object bindings.

2019-10-04drm/i915: Coordinate i915_active with its own mutexChris Wilson1-2/+1
Forgo the struct_mutex serialisation for i915_active, and interpose its own mutex handling for active/retire. This is a multi-layered sleight-of-hand. First, we had to ensure that no active/retire callbacks accidentally inverted the mutex ordering rules, nor assumed that they were themselves serialised by struct_mutex. More challenging though, is the rule over updating elements of the active rbtree. Instead of the whole i915_active now being serialised by struct_mutex, allocations/rotations of the tree are serialised by the i915_active.mutex and individual nodes are serialised by the caller using the i915_timeline.mutex (we need to use nested spinlocks to interact with the dma_fence callback lists). The pain point here is that instead of a single mutex around execbuf, we now have to take a mutex for active tracker (one for each vma, context, etc) and a couple of spinlocks for each fence update. The improvement in fine grained locking allowing for multiple concurrent clients (eventually!) should be worth it in typical loads. v2: Add some comments that barely elucidate anything :( Signed-off-by: Chris Wilson <[email protected]> Reviewed-by: Tvrtko Ursulin <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2019-10-04drm/i915: Pull i915_vma_pin under the vm->mutexChris Wilson1-9/+2
Replace the struct_mutex requirement for pinning the i915_vma with the local vm->mutex instead. Note that the vm->mutex is tainted by the shrinker (we require unbinding from inside fs-reclaim) and so we cannot allocate while holding that mutex. Instead we have to preallocate workers to do allocate and apply the PTE updates after we have we reserved their slot in the drm_mm (using fences to order the PTE writes with the GPU work and with later unbind). In adding the asynchronous vma binding, one subtle requirement is to avoid coupling the binding fence into the backing object->resv. That is the asynchronous binding only applies to the vma timeline itself and not to the pages as that is a more global timeline (the binding of one vma does not need to be ordered with another vma, nor does the implicit GEM fencing depend on a vma, only on writes to the backing store). Keeping the vma binding distinct from the backing store timelines is verified by a number of async gem_exec_fence and gem_exec_schedule tests. The way we do this is quite simple, we keep the fence for the vma binding separate and only wait on it as required, and never add it to the obj->resv itself. Another consequence in reducing the locking around the vma is the destruction of the vma is no longer globally serialised by struct_mutex. A natural solution would be to add a kref to i915_vma, but that requires decoupling the reference cycles, possibly by introducing a new i915_mm_pages object that is own by both obj->mm and vma->pages. However, we have not taken that route due to the overshadowing lmem/ttm discussions, and instead play a series of complicated games with trylocks to (hopefully) ensure that only one destruction path is called! v2: Add some commentary, and some helpers to reduce patch churn.

2019-09-20drm/i915: Mark i915_request.timeline as a volatile, rcu pointerChris Wilson1-1/+1
The request->timeline is only valid until the request is retired (i.e. before it is completed). Upon retiring the request, the context may be unpinned and freed, and along with it the timeline may be freed. We therefore need to be very careful when chasing rq->timeline that the pointer does not disappear beneath us. The vast majority of users are in a protected context, either during request construction or retirement, where the timeline->mutex is held and the timeline cannot disappear. It is those few off the beaten path (where we access a second timeline) that need extra scrutiny -- to be added in the next patch after first adding the warnings about dangerous access. One complication, where we cannot use the timeline->mutex itself, is during request submission onto hardware (under spinlocks). Here, we want to check on the timeline to finalize the breadcrumb, and so we need to impose a second rule to ensure that the request->timeline is indeed valid. As we are submitting the request, it's context and timeline must be pinned, as it will be used by the hardware. Since it is pinned, we know the request->timeline must still be valid, and we cannot submit the idle barrier until after we release the engine->active.lock, ergo while submitting and holding that spinlock, a second thread cannot release the timeline. v2: Don't be lazy inside selftests; hold the timeline->mutex for as long as we need it, and tidy up acquiring the timeline with a bit of refactoring (i915_active_add_request) Signed-off-by: Chris Wilson <[email protected]> Cc: Tvrtko Ursulin <[email protected]> Reviewed-by: Tvrtko Ursulin <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2019-08-16drm/i915: Markup expected timeline locks for i915_activeChris Wilson1-1/+1
As every i915_active_request should be serialised by a dedicated lock, i915_active consists of a tree of locks; one for each node. Markup up the i915_active_request with what lock is supposed to be guarding it so that we can verify that the serialised updated are indeed serialised.

2019-08-16drm/i915: Extract intel_frontbuffer active trackingChris Wilson1-4/+4
Move the active tracking for the frontbuffer operations out of the i915_gem_object and into its own first class (refcounted) object. In the process of detangling, we switch from low level request tracking to the easier i915_active -- with the plan that this avoids any potential atomic callbacks as the frontbuffer tracking wishes to sleep as it flushes.

2019-08-12drm/i915/overlay: Switch to using i915_active trackingChris Wilson1-65/+64
Remove the raw i915_active_request tracking in favour of the higher level i915_active tracking for the sole purpose of making the lockless transition easier in later patches.

2019-08-07drm/i915: rename intel_drv.h to display/intel_display_types.hJani Nikula1-1/+1
Everything about the file is about display, and mostly about types related to display. Move under display/ as intel_display_types.h to reflect the facts. There's still plenty to clean up, but start off with moving the file where it logically belongs and naming according to contents. v2: fix the include guard name in the renamed file Reviewed-by: Chris Wilson <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2019-07-04drm/i915/overlay: Stash the kernel context on initialisationChris Wilson1-3/+7
Simplify runtime request creation by storing the context we need to use during initialisation. This allows us to remove one more hardcoded engine lookup.
