2019-04-13drm/i915: Teach intel_workarounds to use uncore mmio accessChris Wilson
Start weaning ourselves off the implicit I915_WRITE macro madness and start using the explicit intel_uncore mmio access.

2019-04-12drm/panfrost: Add support for 2MB page entriesRob Herring
Add support for 2MB sized pages. This will improve our map and unmap times and save a bit of memory by avoiding 3rd level page tables for contiguous allocations. As we use shmem for buffers and huge page allocations for shmem are off by default, there isn't an improvement out of the box and userspace must enable THP for shmem. It's not clear if the h/w can support 1GB page sizes which standard ARM long format descriptors support. In any case, it is unlikely we'll see any contiguous 1GB allocations on current h/w.

2019-04-12drm/i915: Restore correct bxt_ddi_phy_calc_lane_lat_optim_mask() calculationVille Syrjälä
We are no longer calling bxt_ddi_phy_calc_lane_lat_optim_mask() when intel{hdmi,dp}_compute_config() succeeds, and instead only call it when those fail. This is fallout from the bool->int .compute_config() conversion which failed to invert the return value check before calling bxt_ddi_phy_calc_lane_lat_optim_mask(). Let's just replace it with an early bailout so that it's harder to miss. This restores the correct latency optim setting calculation (which could fix some real failures), and avoids the MISSING_CASE() from bxt_ddi_phy_calc_lane_lat_optim_mask() after intel{hdmi,dp}_compute_config() has failed.

Currently we enable FEC even when DSC is no used. While that is theoretically valid supposedly there isn't much of a benefit from this. But more importantly we do not account for the FEC link bandwidth overhead (2.4%) in the non-DSC link bandwidth computations. So the code may think we have enough bandwidth when we in fact do not.

2019-04-11drm/i915/execlists: Always reset the context's RING registersChris Wilson
During reset, we try and stop the active ring. This has the consequence that we often clobber the RING registers within the context image. When we find an active request, we update the context image to rerun that request (if it was guilty, we replace the hanging user payload with NOPs). However, we were ignoring an active context if the request had completed, with the consequence that the next submission on that request would start with RING_HEAD==0 and not the tail of the previous request, causing all requests still in the ring to be rerun. Rare, but occasionally seen within CI where we would spot that the context seqno would reverse and complain that we were retiring an incomplete request. <0> [412.390350] <idle>-0 3d.s2 408373352us : __i915_request_submit: rcs0 fence 1e95b:3640 -> current 3638 <0> [412.390350] <idle>-0 3d.s2 408373353us : __i915_request_submit: rcs0 fence 1e95b:3642 -> current 3638 <0> [412.390350] <idle>-0 3d.s2 408373354us : __i915_request_submit: rcs0 fence 1e95b:3644 -> current 3638 <0> [412.390350] <idle>-0 3d.s2 408373354us : __i915_request_submit: rcs0 fence 1e95b:3646 -> current 3638 <0> [412.390350] <idle>-0 3d.s2 408373356us : __execlists_submission_tasklet: rcs0 in[0]: ctx=2.1, fence 1e95b:3646 (current 3638), prio=4 <0> [412.390350] i915_sel-4613 0.... 408373374us : __i915_request_commit: rcs0 fence 1e95b:3648 <0> [412.390350] i915_sel-4613 0d..1 408373377us : process_csb: rcs0 cs-irq head=2, tail=3 <0> [412.390350] i915_sel-4613 0d..1 408373377us : process_csb: rcs0 csb[3]: status=0x00000001:0x00000000, active=0x1 <0> [412.390350] i915_sel-4613 0d..1 408373378us : __i915_request_submit: rcs0 fence 1e95b:3648 -> current 3638 <0> [412.390350] <idle>-0 3..s1 408373378us : execlists_submission_tasklet: rcs0 awake?=1, active=5 <0> [412.390350] i915_sel-4613 0d..1 408373379us : __execlists_submission_tasklet: rcs0 in[0]: ctx=2.2, fence 1e95b:3648 (current 3638), prio=4 <0> [412.390350] i915_sel-4613 0.... 408373381us : i915_reset_engine: rcs0 flags=4 <0> [412.390350] i915_sel-4613 0.... 408373382us : execlists_reset_prepare: rcs0: depth<-0 <0> [412.390350] <idle>-0 3d.s2 408373390us : process_csb: rcs0 cs-irq head=3, tail=4 <0> [412.390350] <idle>-0 3d.s2 408373390us : process_csb: rcs0 csb[4]: status=0x00008002:0x00000002, active=0x1 <0> [412.390350] <idle>-0 3d.s2 408373390us : process_csb: rcs0 out[0]: ctx=2.2, fence 1e95b:3648 (current 3640), prio=4 <0> [412.390350] i915_sel-4613 0.... 408373401us : intel_engine_stop_cs: rcs0 <0> [412.390350] i915_sel-4613 0d..1 408373402us : process_csb: rcs0 cs-irq head=4, tail=4 <0> [412.390350] i915_sel-4613 0.... 408373403us : intel_gpu_reset: engine_mask=1 <0> [412.390350] i915_sel-4613 0d..1 408373408us : execlists_cancel_port_requests: rcs0:port0 fence 1e95b:3648, (current 3648) <0> [412.390350] i915_sel-4613 0.... 408373442us : intel_engine_cancel_stop_cs: rcs0 <0> [412.390350] i915_sel-4613 0.... 408373442us : execlists_reset_finish: rcs0: depth->0 <0> [412.390350] ksoftirq-26 3..s. 408373442us : execlists_submission_tasklet: rcs0 awake?=1, active=0 <0> [412.390350] ksoftirq-26 3d.s1 408373443us : process_csb: rcs0 cs-irq head=5, tail=5 <0> [412.390350] i915_sel-4613 0.... 408373475us : i915_request_retire: rcs0 fence 1e95b:3640, current 3648 <0> [412.390350] i915_sel-4613 0.... 408373476us : i915_request_retire: __retire_engine_request(rcs0) fence 1e95b:3640, current 3648 <0> [412.390350] i915_sel-4613 0.... 408373494us : __i915_request_commit: rcs0 fence 1e95b:3650 <0> [412.390350] i915_sel-4613 0d..1 408373496us : process_csb: rcs0 cs-irq head=5, tail=5 <0> [412.390350] i915_sel-4613 0d..1 408373496us : __i915_request_submit: rcs0 fence 1e95b:3650 -> current 3648 <0> [412.390350] i915_sel-4613 0d..1 408373498us : __execlists_submission_tasklet: rcs0 in[0]: ctx=2.1, fence 1e95b:3650 (current 3648), prio=6 <0> [412.390350] i915_sel-4613 0.... 408373500us : i915_request_retire_upto: rcs0 fence 1e95b:3648, current 3648 <0> [412.390350] i915_sel-4613 0.... 408373500us : i915_request_retire: rcs0 fence 1e95b:3642, current 3648 <0> [412.390350] i915_sel-4613 0.... 408373501us : i915_request_retire: __retire_engine_request(rcs0) fence 1e95b:3642, current 3648 <0> [412.390350] i915_sel-4613 0.... 408373514us : i915_request_retire: rcs0 fence 1e95b:3644, current 3648 <0> [412.390350] i915_sel-4613 0.... 408373515us : i915_request_retire: __retire_engine_request(rcs0) fence 1e95b:3644, current 3648 <0> [412.390350] i915_sel-4613 0.... 408373527us : i915_request_retire: rcs0 fence 1e95b:3646, current 3640 <0> [412.390350] <idle>-0 3..s1 408373569us : execlists_submission_tasklet: rcs0 awake?=1, active=1 <0> [412.390350] <idle>-0 3d.s2 408373569us : process_csb: rcs0 cs-irq head=5, tail=1 <0> [412.390350] <idle>-0 3d.s2 408373570us : process_csb: rcs0 csb[0]: status=0x00000001:0x00000000, active=0x1 <0> [412.390350] <idle>-0 3d.s2 408373570us : process_csb: rcs0 csb[1]: status=0x00000018:0x00000002, active=0x5 <0> [412.390350] <idle>-0 3d.s2 408373570us : process_csb: rcs0 out[0]: ctx=2.1, fence 1e95b:3650 (current 3650), prio=6 <0> [412.390350] <idle>-0 3d.s2 408373571us : process_csb: rcs0 completed ctx=2 <0> [412.390350] i915_sel-4613 0.... 408373621us : i915_request_retire: i915_request_retire:253 GEM_BUG_ON(!i915_request_completed(request)) v2: Fixup the cancellation path to drain the CSB and reset the pointers.

2019-04-11drm/i915: Bump ready tasks ahead of busywaitsChris Wilson
Consider two tasks that are running in parallel on a pair of engines (vcs0, vcs1), but then must complete on a shared engine (rcs0). To maximise throughput, we want to run the first ready task on rcs0 (i.e. the first task that completes on either of vcs0 or vcs1). When using semaphores, however, we will instead queue onto rcs in submission order. To resolve this incorrect ordering, we want to re-evaluate the priority queue when each of the request is ready. Normally this happens because we only insert into the priority queue requests that are ready, but with semaphores we are inserting ahead of their readiness and to compensate we penalize those tasks with reduced priority (so that tasks that do not need to busywait should naturally be run first). However, given a series of tasks that each use semaphores, the queue degrades into submission fifo rather than readiness fifo, and so to counter this we give a small boost to semaphore users as their dependent tasks are completed (and so we no longer require any busywait prior to running the user task as they are then ready themselves). v2: Fixup irqsave for schedule_lock (Tvrtko) Testcase: igt/gem_exec_schedule/semaphore-codependency Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Dmitry Rogozhkin <dmitry.v.rogozhkin@intel.com> Cc: Dmitry Ermilov <dmitry.ermilov@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190409152922.23894-1-chris@chris-wilson.co.uk
