2015-12-11drm/i915: mark a newly-created GEM object dirty when filled with dataDave Gordon
When creating a new (pageable) GEM object and filling it with data, we must mark it as 'dirty', i.e. backing store is out-of-date w.r.t. the newly-written content.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.

2015-12-11drm/i915: mark GEM object pages dirty when mapped & written by the CPUDave Gordon
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.

2015-12-11drm: Only merge mode type bits between new probed modesVille Syrjälä
Currently most drivers request that any mode appearing on both the old mode list and the new probed_modes list get their type bits ORed together if the modes are deemed to otherwise match each other. I don't know why anyone would want to merge in the mode type bits from any mode left over from a previous probe. For instance, you could never get rid of ther preferred bit if a matching non-preferred mode is returned by the new probe. So let's not merge anything from the stale old modes, and just replace them outright with matching new modes. If multiple matching modes are produced by the same probe, merging the type bits between them would seem like a sensible thing to do. For a bit of extra finesse if two modes are considered equal we can pick the actual timings from the one marked as preferrred. And if multiple preferred modes are produced by the same probe somehow, we can just favor the first one added to the probed_modes list. You may be asking yourself why we bother with the merging at all if nothing from the old list survives in practice. The only answer I have is "debug output". That is we want to print out a list of pruned modes, which is why we still want to look for duplicates with the old modes. There was a previous attempt to get rid of the mode type merging entirely, but it caused some kind of regression on Daniels's G33 machine. Apparently the sdvo transcoder on said machine started to die at around the same time and has since rotted away totally, so it may have been a red herring. So we don't have to worry about it anymore. The relevant commits are: commit 3fbd6439e463 ("drm: copy mode type in drm_mode_connector_list_update()") commit abce1ec9b08a ("Revert "drm: copy mode type in drm_mode_connector_list_update()"") It was then decided in commit b87577b7c768 ("drm: try harder to avoid regression when merging mode bits") that just qxl virtio are excluded from the merging, while everyone else does it. That is not changed, although now even qxl and virtio will be subject to the previously mentioned logic to choose which actual timings are picked for the new mode. v2: Fix typos in commit message, and clarify the details on the G33 regression from the previous attempt (Daniel) Cc: Marc-André Lureau <marcandre.lureau@redhat.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Adam Jackson <ajax@redhat.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1449234781-22332-1-git-send-email-ville.syrjala@linux.intel.com

2015-12-11drm: Rename MODE_UNVERIFIED to MODE_STALEVille Syrjälä

2015-12-11drm: Don't overwrite UNVERFIED mode status to OKVille Syrjälä
The way the mode probing works is this: 1. All modes currently on the mode list are marked as UNVERIFIED 2. New modes are on the probed_modes list (they start with status OK) 3. Modes are moved from the probed_modes list to the actual mode list. If a mode already on the mode list is deemed to match one of the probed modes, the duplicate is dropped and the mode status updated to OK. After this the probed_modes list will be empty. 4. All modes on the mode list are verified to not violate any constraints. Any that do are marked as such. 5. Any mode left with a non-OK status is pruned from the list, with an appropriate debug message. What all this means is that any mode on the original list that didn't have a duplicate on the probed_modes list, should be left with status UNVERFIED (or previously could have been left with some other status, but never OK). I broke that in commit 05acaec334fc ("drm: Reorganize probed mode validation") by always assigning something to the mode->status during the validation step. So any mode from the old list that still passed the validation would be left on the list with status OK in the end. Fix this by not doing the basic mode validation unless the mode already has status OK (meaning it came from the probed_modes list, or at least a duplicate of it was on that list). This way we will correctly prune away any mode from the old mode list that didn't appear on the probed_modes list.

I didn't convert drm_crtc_init() since passing the varargs through would mean either cpp macros or va_list, and I figured we don't care about these legacy functions enough to warrant the extra pain. @@ identifier dev, crtc, primary, cursor, funcs; @@ int drm_crtc_init_with_planes(struct drm_device *dev, struct drm_crtc *crtc, struct drm_plane *primary, struct drm_plane *cursor, const struct drm_crtc_funcs *funcs + ,const char *name, int DOTDOTDOT ) { ... } @@ identifier dev, crtc, primary, cursor, funcs; @@ int drm_crtc_init_with_planes(struct drm_device *dev, struct drm_crtc *crtc, struct drm_plane *primary, struct drm_plane *cursor, const struct drm_crtc_funcs *funcs + ,const char *name, int DOTDOTDOT ); @@ expression E1, E2, E3, E4, E5; @@ drm_crtc_init_with_planes(E1, E2, E3, E4, E5 + ,NULL ) v2: Split crtc and plane changes apart Pass NULL for no-name instead of "" Leave drm_crtc_init() alone v3: Add ', or NULL...' to @name kernel doc (Jani) Annotate the function with __printf() attribute (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1449670771-2751-1-git-send-email-ville.syrjala@linux.intel.com

There are few defects in vga_get() related to signal hadning: - we shouldn't check for pending signals for TASK_UNINTERRUPTIBLE case; - if we found pending signal we must remove ourself from wait queue and change task state back to running; - -ERESTARTSYS is more appropriate, I guess.

2015-12-10drm/i915: Fix random aux transactions failures.Rodrigo Vivi
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).

2015-12-10drm/i915: intel_ring_initialized() must be simple and inlineDave Gordon
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.

2015-12-10drm/i915: Add reverse mapping between port and intel_encoderTakashi Iwai
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.

2015-12-10drm/i915: Add get_eld audio componentTakashi Iwai
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: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-12-10drm/i915: Do a better job at disabling primary plane in the noatomic case.Maarten Lankhorst
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?

2015-12-10drm/i915: Separate cherryview from valleyviewWayne Boyer
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. Then where appropriate, instances of IS_VALLEYVIEW are replaced with IS_VALLEYVIEW || IS_CHERRYVIEW or equivalent. v2: Use IS_VALLEYVIEW || IS_CHERRYVIEW instead of defining a new macro. Also add followup patches to fix issues discovered during the first review. (Ville) v3: Fix some style issues and one gen check. Remove CRT related changes as CRT is not supported on CHV. (Imre, Ville) v4: Make a few more optimizations.
