We can make the RPM dependency on RC6 explcit in the code by taking an actual RPM reference, instead of avoiding to drop the initial one. This will also enable us to remove the HAS_RUNTIME_PM special casing from more places in the next patch. v2: - fixed typo in commit message (Joonas) Signed-off-by:

I broke AVI/HDMI/SPD infoframes on HSW+ with the register type safety changes. We were supposed to check that the infoframe data register is valid before writing the infoframe data, but the check ended up inverted, and so in practice we never wrote or enabled these infoframes. We were still sending out the GCP infoframe when the sink was deep-color capable. That and the fact that we use a single bool to track our infoframe state meant that the state checker only caught this when a HDMI sink that doesn't do deep-color was used. We really need to fix our infoframe state checking to be much more anal. But in the meantime let's just fix the regression. In fact let's just throw out the register validity check and convert some of the "unknown info frame type" debug messages into MISSING_CASE(). So far we support the same set of infoframe types on all platforms, so the silent debug messages make no sense.

When creating a new (pageable) GEM object and filling it with data, we must mark it as 'dirty', i.e. backing store is out-of-date w.r.t. the newly-written content. This ensures that if the object is evicted under memory pressure, its pages in the pagecache will be written to backing store rather than discarded. Based on an original version by Alex Dai.

In various places, a single page of a (regular) GEM object is mapped into CPU address space and updated. In each such case, either the page or the the object should be marked dirty, to ensure that the modifications are not discarded if the object is evicted under memory pressure. The typical sequence is: va = kmap_atomic(i915_gem_object_get_page(obj, pageno)); *(va+offset) = ... kunmap_atomic(va); Here we introduce i915_gem_object_get_dirty_page(), which performs the same operation as i915_gem_object_get_page() but with the side-effect of marking the returned page dirty in the pagecache. This will ensure that if the object is subsequently evicted (due to memory pressure), the changes are written to backing store rather than discarded. Note that it works only for regular (shmfs-backed) GEM objects, but (at least for now) those are the only ones that are updated in this way -- the objects in question are contexts and batchbuffers, which are always shmfs-backed. Separate patches deal with the cases where whole objects are (or may be) dirtied. v3: Mark two more pages dirty in the page-boundary-crossing cases of the execbuffer relocation code [Chris Wilson] Signed-off-by: -

Mainly aux communications on sink_crc were failing a lot randomly on recent platforms. The first solution was to try to use intel_dp_dpcd_read_wake, but then it was suggested to move retries to drm level. Since drm level was already taking care of retries and didn't want to through random retries on that level the second solution was to put the retries at aux_transfer layer what was nacked. So I realized we had so many retries in different places and started to organize that a bit. During this organization I noticed that we weren't handing at all the case were the message size was zeroed. And this was exactly the case that was affecting sink_crc. Also we weren't respect BSPec who says this size message = 0 or > 20 are forbidden. It is a fact that we still have no clue why we are getting this forbidden value there. But anyway we need to handle that for now so we return -EBUSY and drm level takes care of the retries that are already in place. v2: Print debug messsage when this case is reached as suggested by Jani. v3: This patch is crucial to make PSR test cases reliably working on SKL. So split this patch from the aux re-org series and add a FIXME as a promisse to continue that effort besides reminding to remove the sleep when that is merged. v4: Use a bigger usleep range so kernel doesn't need to be interrupted on a exact time, as suggested by Paulo. But anyway we should discuss the better time ranges on the EBUSY handle re-org at drm level since this one here is temporary. v5: s/1000,1500/1000, 1500/ (by Paulo).

Based on Chris Wilson's patch from 6 months ago, rebased and adapted. The current implementation of intel_ring_initialized() is too heavyweight; it's a non-inlined function that chases several levels of pointers. This wouldn't matter too much if it were rarely called, but it's used inside the iterator test of for_each_ring() and is therefore called quite frequently. So let's make it simple and inline ... The idea here is to use ring->dev as an indicator showing which engines have been initialised and are therefore to be included in iterations that use for_each_ring(). This allows us to avoid multiple memory references and a (non-inlined) function call on each iteration of each such loop.

This patch adds a reverse mapping from a digital port number to intel_encoder object containing the corresponding intel_digital_port. It simplifies the query of the encoder a lot. Note that, even if it's a valid digital port, the dig_port_map[] might point still to NULL -- usually it implies a DP MST port. Due to this fact, the NULL check in each place has no WARN_ON() and just skips the port. Once when the situation changes in future, we might introduce WARN_ON() for a more strict check.

Implement a new i915_audio_component_ops, get_eld(). It's called by the audio driver to fetch the current audio status and ELD of the given HDMI/DP port. It returns the size of expected ELD bytes if it's valid, zero if no valid ELD is found, or a negative error code. The current state of audio on/off is stored in the given pointer, too. Note that the returned size isn't limited to the given max bytes. If the size is greater than the max bytes, it means that only a part of ELD has been copied back. For achieving this implementation, a new field audio_connector is added to struct intel_digital_port. It points to the connector assigned to the given digital port. It's set/reset at each audio enable/disable call in intel_audio.c, and protected with av_mutex. Reviewed-by:

When disable_noatomic is called plane_mask is not correct yet, and plane_state->visible = true is left as true after disabling the primary plane. Other planes are already disabled as part of crtc sanitization, only the primary is left active. But the plane_mask is not updated here. It gets updated during fb takeover in modeset_gem_init, or set to the new value on resume. This means that to disable the primary plane 1 << drm_plane_index(primary) needs to be used. Afterwards because the crtc is no longer active it's forbidden to keep plane_state->visible set, or a WARN_ON in intel_plane_atomic_calc_changes triggers. There are other code points that rely on accurate plane_state->visible too, so make sure the bool is cleared. The other planes are already disabled in intel_sanitize_crtc, so they don't have to be handled here. Cc: stable@vger.kernel.org #v4.3, v4.2?

The cherryview device shares many characteristics with the valleyview device. When support was added to the driver for cherryview, the corresponding device info structure included .is_valleyview = 1. This is not correct and leads to some confusion. This patch changes .is_valleyview to .is_cherryview in the cherryview device info structure and simplifies the IS_CHERRYVIEW macro.
