2019-06-26drm/i915: Only recover active enginesChris Wilson2-17/+26
If we issue a reset to a currently idle engine, leave it idle afterwards. This is useful to excise a linkage between reset and the shrinker. When waking the engine, we need to pin the default context image which we use for overwriting a guilty context -- if the engine is idle we do not need this pinned image! However, this pinning means that waking the engine acquires the FS_RECLAIM, and so may trigger the shrinker. The shrinker itself may need to wait upon the GPU to unbind and object and so may require services of reset; ergo we should avoid the engine wake up path. The danger in skipping the recovery for idle engines is that we leave the engine with no context defined, which may interfere with the operation of the power context on some older platforms. In practice, we should only be resetting an active GPU but it something to look out for on Ironlake (if memory serves).

2019-06-26drm/i915: Fix various tracepoints for gen2Ville Syrjälä2-45/+35
Gen2 doesn't have a frame counter and apparently we no longer provide a fake .get_vblank_counter() hook for it. That means all tracepoints calling that hook will oops. Update the tracepoints to use intel_crtc_get_vblank_counter() which will gracefully fall back to using the software counter. This is actually a better approach since we now get (hopefully accurate) frame numbers in the traces. This also gets rid of the raw driver->get_vblank_counter() calls, which we need to do in order to switch to the per-crtc vblank vfuncs. v2: Deal with new tracepoints v3: Use a distinct variable name for the internal crtc iterator (Chris) Cc: Shawn Guo <shawn.guo@linaro.org> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Fixes: 967dd4841787 ("drm: remove drm_vblank_no_hw_counter assignment from driver code") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190619170842.20579-2-ville.syrjala@linux.intel.com

2019-06-26drm/i915/gt: Drop stale commentary for timeline densityChris Wilson1-10/+0
We no longer allocate a contiguous set of timeline ids for all engines upon creation, so we no longer should assume that the timelines are densely allocated within a context. Hopefully, the set of fences used within a workload are still dense enough for us to take advantage of the compressed radix tree used for the syncmap.

2019-06-25drm/i915/execlists: Convert recursive defer_request() into iterativeChris Wilson1-25/+27
As this engine owns the lock around rq->sched.link (for those waiters submitted to this engine), we can use that link as an element in a local list. We can thus replace the recursive algorithm with an iterative walk over the ordered list of waiters.
