With the subdirectories we lost the ability to build individual files on the command line, for example: $ make drivers/gpu/drm/i915/display/intel_display.o This was due to the top level directory missing from header search path. Add the header search paths to subdir Makefiles. Note that none of the other options in the top level i915 Makefile are taken into account when building individual files. Usually this is not a concern. Reported-by:

Since the reset path wants to recover the engines itself, it only wants to reinitialise the hardware using i915_gem_init_hw(). Pull the call to intel_engines_resume() to the module init/resume path so we can avoid it during reset. Fixes: 79ffac85 ("drm/i915: Invert the GEM wakeref hierarchy") Signed-off-by:

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). Fixes: 79ffac85 ("drm/i915: Invert the GEM wakeref hierarchy") Signed-off-by:

Stop using the irq vfuncs under drm_driver. That's not going to fly in a mixed gen environment since the structure is shared between all the devices. v2: Allow intel_irq_uninstall() to be called twice due to intel_modeset_cleanup() calling it as well.

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: 967dd484 ("drm: remove drm_vblank_no_hw_counter assignment from driver code") Signed-off-by:

In order for the reset count to be accurate across our selftest, we need to prevent the background retire worker from modifying our expected state. To preserve the intent of symmetry, we apply this to both i915_reset and i915_reset_engine, even though it strictly only affects i915_reset_engine currently. Signed-off-by:

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.

The Demand Prefetch workaround (binding table prefetching) only applies to Icelake A0/B0. But the Sampler Prefetch workaround needs to be applied to all Gen11 steppings, according to a programming note in the SARCHKMD documentation.

In the unlikely case (thank you CI!), we may find ourselves wanting to issue a preemption but having no runnable requests left. In this case, we set the semaphore before computing the preemption and so must unset it before forgetting (or else we leave the machine busywaiting until the next request comes along and so likely hang). v2: Replace readback with only a wmb after asserting the semaphore Signed-off-by:

As we have already plugged the w->dma into the reservation_object, and have set ourselves up to automatically signal the request and w->dma on completion, we do not need to export the rq->fence directly and just use the w->dma fence. This avoids having to take the reservation_lock inside the worker which cross-release lockdep would complain about. :) Signed-off-by:
