drm/i915: add minimal i915_gem_object_frontbuffer.h Split out frontbuffer related declarations and static inlines from gem/i915_gem_object.h into new gem/i915_gem_object_frontbuffer.h. The main goal is to reduce header interdependencies. With gem/i915_gem_object.h including display/intel_frontbuffer.h, modification of the latter causes a whopping 300+ objects to be rebuilt, while many of the source files actually needing it aren't explicitly including it at all. After the change, only 21 objects depend on display/intel_frontbuffer.h, directly or indirectly.

drm/i915/display: rename display version macros While converting the rest of the driver to use GRAPHICS_VER() and MEDIA_VER(), following what was done for display, some discussions went back on what we did for display: 1) Why is the == comparison special that deserves a separate macro instead of just getting the version and comparing directly like is done for >, >=, <=? 2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for brevity. If we remove the current users of IS_DISPLAY_VER(), we could actually repurpose it for a range check With (1) there could be an advantage if we used gen_mask since multiple conditionals be combined by the compiler in a single and instruction and check the result. However a) INTEL_GEN() doesn't use the mask since it would make the code bigger everywhere else and b) in the cases it made sense, it also made sense to convert to the _RANGE() variant. So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER() users to use == and != operators. Aside from the definition changes, this was done by the following semantic patch: @@ expression dev_priv, E1; @@ - !IS_DISPLAY_VER(dev_priv, E1) + DISPLAY_VER(dev_priv) != E1 @@ expression dev_priv, E1; @@ - IS_DISPLAY_VER(dev_priv, E1) + DISPLAY_VER(dev_priv) == E1 @@ expression dev_priv, from, until; @@ - IS_DISPLAY_RANGE(dev_priv, from, until) + IS_DISPLAY_VER(dev_priv, from, until) Cc: Jani Nikula <jani.nikula@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> [Jani: Minor conflict resolve while applying.] Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20210413051002.92589-4-lucas.demarchi@intel.com

drm/i915: Fix overlay frontbuffer tracking We don't have a persistent fb holding a reference to the frontbuffer object, so every time we do the get+put we throw the frontbuffer object immediately away. And so the next time around we get a pristine frontbuffer object with bits==0 even for the old vma. This confuses the frontbuffer tracking code which understandably expects the old frontbuffer to have the overlay's bit set. Fix this by hanging on to the frontbuffer reference until the next flip. And just to make this a bit more clear let's track the frontbuffer explicitly instead of just grabbing it via the old vma.

drm/i915/gem: Drop lru bumping on display unpinning Simplify the frontbuffer unpin by removing the lock requirement. The LRU bumping was primarily to protect the GTT from being evicted and from frontbuffers being eagerly shrunk. Now we protect frontbuffers from the shrinker, and we avoid accidentally evicting from the GTT, so the benefit from bumping LRU is no more, and we can save more time by not.

drm/i915: Fix overlay frontbuffer tracking We don't have a persistent fb holding a reference to the frontbuffer object, so every time we do the get+put we throw the frontbuffer object immediately away. And so the next time around we get a pristine frontbuffer object with bits==0 even for the old vma. This confuses the frontbuffer tracking code which understandably expects the old frontbuffer to have the overlay's bit set. Fix this by hanging on to the frontbuffer reference until the next flip. And just to make this a bit more clear let's track the frontbuffer explicitly instead of just grabbing it via the old vma.

However, we are not allowed to use rcu_barrier() beneath the dma_resv (i.e. object) lock and do not take lightly the prospect of unlocking a mutex deep in the bowels of the routine. i915_gem_object_unbind() itself does not need the object lock, and it turns out the callers do not need to the unbind as part of a locked sequence around set-cache-level, so rearrange the code to avoid taking the object lock in the callers. <4> [186.816311] ====================================================== <4> [186.816313] WARNING: possible circular locking dependency detected <4> [186.816316] 5.4.0-rc8-CI-CI_DRM_7486+ #1 Tainted: G U <4> [186.816318] ------------------------------------------------------ <4> [186.816320] perf_pmu/1321 is trying to acquire lock: <4> [186.816322] ffff88849487c4d8 (&mm->mmap_sem#2){++++}, at: __might_fault+0x39/0x90 <4> [186.816331] but task is already holding lock: <4> [186.816333] ffffe8ffffa05008 (&cpuctx_mutex){+.+.}, at: perf_event_ctx_lock_nested+0xa9/0x1b0 <4> [186.816339] which lock already depends on the new lock. <4> [186.816341] the existing dependency chain (in reverse order) is: <4> [186.816343] -> #6 (&cpuctx_mutex){+.+.}: <4> [186.816349] __mutex_lock+0x9a/0x9d0 <4> [186.816352] perf_event_init_cpu+0xa4/0x140 <4> [186.816357] perf_event_init+0x19d/0x1cd <4> [186.816362] start_kernel+0x372/0x4f4 <4> [186.816365] secondary_startup_64+0xa4/0xb0 <4> [186.816381] -> #5 (pmus_lock){+.+.}: <4> [186.816385] __mutex_lock+0x9a/0x9d0 <4> [186.816387] perf_event_init_cpu+0x6b/0x140 <4> [186.816404] cpuhp_invoke_callback+0x9b/0x9d0 <4> [186.816406] _cpu_up+0xa2/0x140 <4> [186.816409] do_cpu_up+0x61/0xa0 <4> [186.816411] smp_init+0x57/0x96 <4> [186.816413] kernel_init_freeable+0xac/0x1c7 <4> [186.816416] kernel_init+0x5/0x100 <4> [186.816419] ret_from_fork+0x24/0x50 <4> [186.816421] -> #4 (cpu_hotplug_lock.rw_sem){++++}: <4> [186.816424] cpus_read_lock+0x34/0xd0 <4> [186.816427] rcu_barrier+0xaa/0x190 <4> [186.816429] kernel_init+0x21/0x100 <4> [186.816431] ret_from_fork+0x24/0x50 <4> [186.816433] -> #3 (rcu_state.barrier_mutex){+.+.}: <4> [186.816436] __mutex_lock+0x9a/0x9d0 <4> [186.816438] rcu_barrier+0x23/0x190 <4> [186.816502] i915_gem_object_unbind+0x3a6/0x400 [i915] <4> [186.816537] i915_gem_object_set_cache_level+0x32/0x90 [i915] <4> [186.816571] i915_gem_object_pin_to_display_plane+0x5d/0x160 [i915] <4> [186.816612] intel_pin_and_fence_fb_obj+0x9e/0x200 [i915] <4> [186.816679] intel_plane_pin_fb+0x3f/0xd0 [i915] <4> [186.816717] intel_prepare_plane_fb+0x130/0x520 [i915] <4> [186.816722] drm_atomic_helper_prepare_planes+0x85/0x110 <4> [186.816761] intel_atomic_commit+0xc6/0x350 [i915] <4> [186.816764] drm_atomic_helper_update_plane+0xed/0x110 <4> [186.816768] setplane_internal+0x97/0x190 <4> [186.816770] drm_mode_setplane+0xcd/0x190 <4> [186.816773] drm_ioctl_kernel+0xa7/0xf0 <4> [186.816775] drm_ioctl+0x2e1/0x390 <4> [186.816778] do_vfs_ioctl+0xa0/0x6f0 <4> [186.816780] ksys_ioctl+0x35/0x60 <4> [186.816782] __x64_sys_ioctl+0x11/0x20 <4> [186.816785] do_syscall_64+0x4f/0x210 <4> [186.816787] entry_SYSCALL_64_after_hwframe+0x49/0xbe <4> [186.816789] -> #2 (reservation_ww_class_mutex){+.+.}: <4> [186.816793] __ww_mutex_lock.constprop.15+0xc3/0x1090 <4> [186.816795] ww_mutex_lock+0x39/0x70 <4> [186.816798] dma_resv_lockdep+0x10e/0x1f7 <4> [186.816800] do_one_initcall+0x58/0x2ff <4> [186.816802] kernel_init_freeable+0x137/0x1c7 <4> [186.816804] kernel_init+0x5/0x100 <4> [186.816806] ret_from_fork+0x24/0x50 <4> [186.816808] -> #1 (reservation_ww_class_acquire){+.+.}: <4> [186.816811] dma_resv_lockdep+0xec/0x1f7 <4> [186.816813] do_one_initcall+0x58/0x2ff <4> [186.816815] kernel_init_freeable+0x137/0x1c7 <4> [186.816817] kernel_init+0x5/0x100 <4> [186.816819] ret_from_fork+0x24/0x50 <4> [186.816820] -> #0 (&mm->mmap_sem#2){++++}: <4> [186.816824] __lock_acquire+0x1328/0x15d0 <4> [186.816826] lock_acquire+0xa7/0x1c0 <4> [186.816828] __might_fault+0x63/0x90 <4> [186.816831] _copy_to_user+0x1e/0x80 <4> [186.816834] perf_read+0x200/0x2b0 <4> [186.816836] vfs_read+0x96/0x160 <4> [186.816838] ksys_read+0x9f/0xe0 <4> [186.816839] do_syscall_64+0x4f/0x210 <4> [186.816841] entry_SYSCALL_64_after_hwframe+0x49/0xbe <4> [186.816843] other info that might help us debug this: <4> [186.816846] Chain exists of: &mm->mmap_sem#2 --> pmus_lock --> &cpuctx_mutex <4> [186.816849] Possible unsafe locking scenario: <4> [186.816851] CPU0 CPU1 <4> [186.816853] ---- ---- <4> [186.816854] lock(&cpuctx_mutex); <4> [186.816856] lock(pmus_lock); <4> [186.816858] lock(&cpuctx_mutex); <4> [186.816860] lock(&mm->mmap_sem#2); <4> [186.816861] *** DEADLOCK *** Closes: https://gitlab.freedesktop.org/drm/intel/issues/728 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Andi Shyti <andi.shyti@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191206105527.1130413-5-chris@chris-wilson.co.uk

drm/i915: Coordinate i915_active with its own mutex 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 <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191004134015.13204-6-chris@chris-wilson.co.uk

drm/i915: Pull i915_vma_pin under the vm->mutex 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.

drm/i915: Mark i915_request.timeline as a volatile, rcu pointer 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 <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190919111912.21631-1-chris@chris-wilson.co.uk
