Remove the struct_mutex requirement around dev_priv->mm.bound_list and dev_priv->mm.unbound_list by giving it its own spinlock. This reduces one more requirement for struct_mutex and in the process gives us slightly more accurate unbound_list tracking, which should improve the shrinker - but the drawback is that we drop the retirement before counting so i915_gem_object_is_active() may be stale and lead us to underestimate the number of objects that may be shrunk (see commit bed50aea ("drm/i915/shrinker: Flush active on objects before counting")). v2: Crosslink the spinlock to the lists it protects, and btw this changes s/obj->global_link/obj->mm.link/ v3: Fix decoupling of old links in i915_gem_object_attach_phys() v3.1: Fix the fix, only unlink if it was linked v3.2: Use a local for to_i915(obj->base.dev)->mm.obj_lock Signed-off-by:

In the next patch, we want to reduce the lock coverage within the shrinker, and one of the dangerous walks we have is over obj->vma_list. We are only walking the obj->vma_list in order to check whether it has been permanently pinned by HW access, typically via use on the scanout. But we have a couple of other long term pins, the context objects for which we currently have to check the individual vma pin_count. If we instead mark these using obj->pin_display, we can forgo the dangerous and sometimes slow list iteration. v2: Rearrange code to try and avoid confusion from false associations due to arrangement of whitespace along with rebasing on obj->pin_global.

It has now lost its meaning (it shows more than just pin_display), I do not believe that we are using in preference to the complete listing from i915_gem_gtt, or the listing from i915_gem_framebuffer, or the listing of active display objects in i915_display_info. Signed-off-by:

In the next patch, we want to extend use of the global pin counter for semi-permanent pinning of context/ring objects. Given that we plan to extend the usage to encompass a disparate set of objects, we want a name that reflects both and should entail less confusion. Signed-off-by:

Chris Wilson authored
Since we occasionally stuff an error pointer into obj->mm.pages for a semi-permanent or even permanent failure, we have to be more careful and not just test against NULL when deciding if the object has a complete set of its concurrent pages. Signed-off-by:

Apparently RC6 residency is lower than expected with EI mode for most of the cases on CNL A0, B0 and C0. This Wa doesn't solve our lower residency, but I believe it is better to have it since EI is not expected to work by HW engineers anyways.

Always try to stop the rings, even if the GPU reset itself has been disabled (via modparam i915.reset). This should at least stop the hw from spinning in the background consuming resources (e.g. power and memory bandwidth) letting the system rest-in-peace.

Before modifying the ring register (RING_START, HEAD, TAIL, CTL) we first make sure it is stopped (or else the hw may not resample the registers). However, we do not need to let the hw restart until after we have reprogrammed all the rings. This should help prevent situations where pending operations on the ring may resume (because we are trying to re-initialize following an unsuccessful GPU hang, i.e. from i915_gem_unset_wedged).

Since the removal of the stop_machine(), it is allowed and expected for the nop_submit_request() and nop_complete_submit_request() to run in parallel to the i915_gem_set_wedged() processing. As such we can no longer assert that i915_gem_set_wedged() has completed inside the stop_machine prior to the individual nop_submit_request execution.

Rather that plumb the link parameters separately to intel_ddi_pre_enable_dp() let's just pass the entire crtc state. intel_ddi_pre_enable_hdmi() already took the crtc state, but for some reason intel_ddi_pre_enable() still wanted to extract has_infoframe from therein and pass it in separately.

We read the dp dual mode Adapter identifier to detect the LSPCON device. It's been observed from the CI testing that in few cases, this read can get delayed or fail.

Our current logic to read LSPCON's current mode, stops retries and breaks wait-loop, if it gets LSPCON_MODE_INVALID as return from the core function. This doesn't allow us to try reading the mode again. This patch removes this condition and allows retries reading the currnt mode until timeout. This also fixes/prevents some of the noise in form of debug messages while running IGT CI test cases.

From the CI builds, its been observed that during a driver reload/insert, dp dual mode read function sometimes fails to read from LSPCON device over i2c-over-aux channel.
