Now that the infoframe hooks are part of the intel_dig_port, we can use the normal .write_infoframe() hook to update the VSC SDP. We do need to deal with the size difference between the VSC DIP and the others though. Another minor snag is that the compiler will complain to use if we keep using enum hdmi_infoframe_type type and passing in the DP define instead, so et's just change to unsigned int all over for the inforframe type. v2: Rebase due to other PSR changes Reviewed-by:

HDMI Mode selection on CNL is on CFGCR0 for that PLL, not on in a global CTRL1 as it was on SKL. The original patch addressed this difference, but leaving behind this single entry here. So we were checking the wrong bits during the PLL initialization and consequently avoiding the CFGCR1 setup during HDMI initialization. Luckly when only HDMI was in use BIOS had already setup this for us. But the dual display with hot plug were messed up.

On PLL Enable sequence we need to "Configure DPCLKA_CFGCR0 to turn on the clock for the DDI and map the DPLL to the DDI" So we first do the map and then we unset DDI_CLK_OFF to turn the clock on. We do this in 2 separated steps. However, on this second step where we should only unset the off bit we are also unmapping the ddi from the pll. So we end up using the pll 0 for almost everything. Consequently breaking cases with more than one display.

If we fail to recover the HW state upon resume (i.e. our attempt to clear the wedged bit and reset during i915_gem_sanitize() fails), then skip the HW restart inside i915_gem_init_hw(). We will ultimately do the HW restart when successfully unwedging and resetting the HW later, but attempting to restore a wedged device upon resume is risky as the HW is in an unknown state. v2: Suppress the error message when detecting the already wedged HW.

We free objects in bulk after they wait for their RCU grace period. Currently, we take struct_mutex and unbind all the objects. This can lead to a long lock duration during which time those objects have their pages unfreeable (i.e. the shrinker is prevented from reaping those pages). If we only process a single object under the struct_mutex and then free the pages, the number of objects locked away from the shrinker is minimal and we allow regular clients better access to struct_mutex if they need it.

Inspired by Tvrtko's critique of the reaping of the stale contexts before allocating a new one, also limit the freed object reaping to the oldest stale object before allocating a fresh object. Unlike contexts, objects may have radically different sizes of backing storage, but similar to contexts, while we want to prevent starvation due to excessive freed lists, we also do not want to delay fresh allocations for too long. Only freeing the oldest on the freed object list before each allocation is a reasonable compromise. v2: Only a single consumer of llist_del_first() is allowed (although multiple llist_add are still allowed in parallel). Unlike i915_gem_context, i915_gem_flush_free_objects() is itself not serialized and so we need to add our own spinlock. Otherwise KASAN eventually spots a use-after-free for the race on *first->next.

Prefer to defer activating our GEM shrinker until we have a few megabytes to free; or we have accumulated sufficient mempressure by deferring the reclaim to force a shrink. The intent is that because our objects may typically be large, we are too effective at shrinking and are not rewarded for freeing more pages than the batch. It will also defer the initial shrinking to hopefully put it at a lower priority than say the buffer cache (although it will balance out over a number of reclaims, with GEM being more bursty). v2: Give it a feedback system to try and tune the batch size towards an effective size for the available objects. v3: Start keeping track of shrinker stats in debugfs v4: Protect against finding no shrinkable objects (div-by-zero) Signed-off-by:

shrink_slab() allows us to report back the number of objects we successfully scanned (out of the target shrinkctl->nr_to_scan). As report the number of pages owned by each GEM object as a separate item to the shrinker, we cannot precisely control the number of shrinker objects we scan on each pass; and indeed may free more than requested. If we fail to tell the shrinker about the number of objects we process, it will continue to hold a grudge against us as any objects left unscanned are added to the next reclaim -- and so we will keep on "unfairly" shrinking our own slab in comparison to other slabs. v2: fixup the misplaced addition, we want to count everything we scan (to match the number we reported earlier) not just the objects we successfully validated and freed.

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:
