2015-12-16drm/i915/bios: move debug logging about VBT source to intel_parse_bios()Jani Nikula
The decision about which source will be used for VBT is done in intel_parse_bios(), not in the VBT validation function. Make the VBT validation function strictly about validation, and move the debug logging to where it logically belongs. Also split the logging about where the valid VBT was found and what the signature is. This will make even more sense in the future when the validation for ACPI OpRegion based VBT takes place at OpRegion setup time. v2: Split logging about VBT signature and BDB version.

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When creating a new (pageable) GEM object and filling it with data, we must mark it as 'dirty', i.e. backing store is out-of-date w.r.t. the newly-written content.

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.

2015-12-10drm/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: eliminate 'temp' in gen8_for_each_{pdd, pdpe, pml4e} macrosDave Gordon
All of these iterator macros require a 'temp' argument, used merely to hold internal partial results. We can instead declare the temporary variable inside the macro, so the caller need not provide it. Some of the old code contained nested iterators that actually reused the same 'temp' variable for both inner and outer instances. It's quite surprising that this didn't introduce bugs! But it does show that the value of 'temp' isn't required to persist during the iterated body.

2015-12-09drm/i915: Add soft-pinning API for execbufferChris Wilson
Userspace can pass in an offset that it presumes the object is located at. The kernel will then do its utmost to fit the object into that location. The assumption is that userspace is handling its own object locations (for example along with full-ppgtt) and that the kernel will rarely have to make space for the user's requests. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> v2: Fixed incorrect eviction found by Michal Winiarski - fix suggested by Chris Wilson. Fixed incorrect error paths causing crash found by Michal Winiarski. (Not published externally) v3: Rebased because of trivial conflict in object_bind_to_vm. Fixed eviction to allow eviction of soft-pinned objects when another soft-pinned object used by a subsequent execbuffer overlaps reported by Michal Winiarski. (Not published externally) v4: Moved soft-pinned objects to the front of ordered_vmas so that they are pinned first after an address conflict happens to avoid repeated conflicts in rare cases (Suggested by Chris Wilson). Expanded comment on drm_i915_gem_exec_object2.offset to cover this new API. v5: Added I915_PARAM_HAS_EXEC_SOFTPIN parameter for detecting this capability (Kristian). Added check for multiple pinnings on eviction (Akash). Made sure buffers are not considered misplaced without the user specifying EXEC_OBJECT_SUPPORTS_48B_ADDRESS. User must assume responsibility for any addressing workarounds. Updated object2.offset field comment again to clarify NO_RELOC case (Chris). checkpatch cleanup. v6: Trivial rebase on latest drm-intel-nightly v7: Catch attempts to pin above the max virtual address size and return EINVAL (Tvrtko). Decouple EXEC_OBJECT_SUPPORTS_48B_ADDRESS and EXEC_OBJECT_PINNED flags, user must pass both flags in any attempt to pin something at an offset above 4GB (Chris, Daniel Vetter).

As described in the code comment, I couldn't set the minimum RPS frequency on my BYT-M B0 to the minimum allowed as reported by Punit. Fix this by clamping the minimum value to the first one that was accepted on my machine. Atm this issue doesn't cause any test failures, since in igt/pm_rps we only check the cached version of the current frequency which is the same what has been set. In the future we'll add checks for the actual frequency too, and for that to pass this fix is necessary.

2015-12-08drm/i915: Leave FDI running after failed link training on LPT-HVille Syrjälä
Currently we disable some parts of FDI setup after a failed link training. But despite that we continue with the modeset as if everything is fine. This results in tons of noise from the state checker, and it means we're not following the proper modeset sequence for the rest of crtc enabling, nor for crtc disabling. Ideally we should abort the modeset and follow the proper disable sequence to shut off everything we enabled so far, but that would require a big rework of the modeset code. So instead just leave FDI up and running in its untrained state, and log an error. This is what we do on older platforms too. v2: Fix a typo in the commit message Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1449260570-14670-1-git-send-email-ville.syrjala@linux.intel.com

Bspec modeset sequence tells us to disable the PCH transcoder and FDI after the CRT port on LPT-H, so let's do that. And the CRT port should be disabled after the pipe, as we do on other PCH platforms too since commit 1ea56e269e13 ("drm/i915: Disable CRT port after pipe on PCH platforms") commit 00490c22b1b5 ("drm/i915: Consider SPLL as another shared pll, v2.") moved the SPLL disable from the .post_disable() hook to some upper level code, so we can just move the CRT port disabling into the .post_disable() hook.

2015-12-08drm/i915: Disable CLKOUT_DP bending on LPT/WPT as neededVille Syrjälä
When we want to use SPLL for FDI we want SSC, which means we have to disable clock bending for the PCH SSC reference (bend and spread are mutually exclusive). So let's turn off bending when we want spread. In case the BIOS enabled clock bending for some reason we'll just turn it off and enable the spread mode instead. Not sure what happens if the BIOS is actually using the bend source for HDMI at this time, but I suppose it should be no worse than what already happens when we simply turn on the spread. We don't currently use the bend source for anything, and only use the PCH SSC reference for the SPLL to drive FDI (always with spread). v2: Fix the %5 vs %10 fumble for SSCDITHPHASE (Paulo) Add 'WARN_ON(steps % 5 != 0)' sanity check (Paulo) Fix typos in commit message (Paulo) Cc: Paulo Zanoni <przanoni@gmail.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1449260379-14093-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com>

2015-12-07drm/i915: Fix idle_frames counter.Rodrigo Vivi
'commit 97173eaf5 ("drm/i915: PSR: Increase idle_frames")' was a mistake. The special case it tried to cover was already being covered by the DP_PSR_NO_TRAIN_ON_EXIT. So this ended up duplicated. So, instead of reverting that let's take this opportunity and unify the idle_frame definition in a single place so we standardize the access and avoid room for that same mistake again. Few changes with this patch: 1. Instead of just respecting the VBT we set a global minumum with max(). So we are sure that we will avoid corner cases in case VBT is doing something we don't understand. 2. Instead of minimum 5 we use 6. When introducing the idle_frames += 4 case we considered that minimum was 2. All because the off-by-one issue. v2: Unified idle_frame definition.
