When gathering the pages from our backing storage we expect get_pages() to either give us our sg_table or an err ptr. However when gathering our fake pages for stolen memory we may return NULL in the event of a failure. To prevent any funny business we should therefore return the proper err ptr value.

Since we can retire requests from multiple paths, we cannot assume that i915_gem_retire_requests() is the sole path on which we can transition to gt.active_requests == 0. A consequence of this is that we would skip the function if we had already retired all the requests and not scheduled the idle worker. This is fallout from changing the routine from considering active_engines (for which it was the only consumer) to active_requests. v2: Move kicking the idle working to i915_gem_request_retire() otherwise we could postpone the idle callback everytime we called retire_requests even though we did no work. v3: We only need to move the idle work kicking! v4: Drop the BUG_ON(!awake) as we may be called from the shrinker in the middle of constructing a request before we have marked the device awake. v5: Add a BUG_ON() for active_requests underflow upon retirement (Joonas) Fixes: 28176ef4 ("drm/i915: Reserve space in the global seqno during request allocation") Signed-off-by:

I tried to avoid having to track the write for every VMA by only tracking writes to the ggtt. However, for the purposes of frontbuffer tracking this is insufficient as we need to invalidate around writes not just to the the ggtt but all aliased ppgtt views of the framebuffer. By moving the critical section to the object and only doing so for framebuffer writes we can reduce the tracking even further by only watching framebuffers and not vma. Signed-off-by:

We need to clean up the global_timeline in i915_gem_load_cleanup. v2: don't forget about the struct_mutex, and also WARN_ON if we have any remaining timelines before purging the global_timeline. v3: it might be a good idea to first remove the global_timeline...duh!

We already have an i915_address_space_init, so for symmetry we should also have a _fini, plus we already open code it twice. This then also fixes a bug where we leak the timeline for the ggtt vm. v2: don't forget about the struct_mutex for the ggtt path.

We should never be called via obj->ops->release() on anything other than a fully formed stolen object, so raise that to an assert. In the process tidy up a comment and variable no longer used outside of a conditional BUG. Reported-by:

We don't spam the debug when we create a normal object, nor when we allocate their pages. Yet we do for stolen objects, and since these are quite frequently used (at least once per context), the resulting spam floods the dmesg in CI. Signed-off-by:

We use DRM_DEBUG() when reporting on user actions, to try and keep intentional errors out of the CI dmesg. Demote the debug from i915_gem_open() similarly so that it is only apparent with drm.debug & 1 like its brethren. Signed-off-by:

It looks to me skl_update_scaler will already log interesting debug messages when the state transitions or there is an error. In this case it feels we can remove the two unconditional debug messages which happen immediately before calling skl_update_scaler. This way we get rid of the sole debug message when switching virtual terminals for example. Signed-off-by:

The graphics driver is supposed to define the DIDL, which are used for _DOD, not the BIOS. Restore that behaviour. This is basically a revert of commit 3143751f Author: Zhang Rui <rui.zhang@intel.com> Date: Mon Mar 29 15:12:16 2010 +0800 drm/i915: set DIDL using the ACPI video output device _ADR method return. which went out of its way to cater to a specific BIOS, setting up DIDL based on _ADR method. Perhaps that approach worked on that specific machine, but on the machines I checked the _ADR method invents the device identifiers out of thin air if DIDL has not been set. The source for _ADR is also supposed to be the DIDL set by the driver, not the other way around. With this, we'll also limit the number of outputs to what the driver actually has. A side effect of this change is that the DIDL, and by proxy CADL, will be initialized in the order of the connector list. That, in turn, has internal panels in front, ensuring they're included in the DIDL and CADL lists. Hopefully this ensures the BIOS does not block backlight hotkey events, thinking the internal panel is off. v2: do not set ACPI_DEVICE_ID_SCHEME in the device id (Peter Wu) v3: Rebase Cc: Peter Wu <peter@lekensteyn.nl> Cc: Rainer Koenig <Rainer.Koenig@ts.fujitsu.com> Cc: Jan-Marek Glogowski <glogow@fbihome.de> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Marcos Paulo de Souza <marcos.souza.org@gmail.com> Cc: Paolo Stivanin <paolostivanin@fastmail.fm> Tested-by:
