2016-10-25drm/i915: New structure to contain GuC logging related fieldsAkash Goel
So far there were 2 fields related to GuC logs in 'intel_guc' structure. For the support of capturing GuC logs & storing them in a local buffer, multiple new fields would have to be added. This warrants a separate structure to contain the fields related to GuC logging state. Added a new structure 'intel_guc_log' and instance of it inside 'intel_guc' structure. v2: Rebase.

2016-10-25drm/i915: Add GuC ukernel logging related fields to fw interface fileSagar Arun Kamble
The first page of the GuC log buffer contains state info or meta data which is required to parse the logs contained in the subsequent pages. The structure representing the state info is added to interface file as Driver would need to handle log buffer flush interrupts from GuC. Added an enum for the different message/event types that can be send by the GuC ukernel to Host. Also added 2 new Host to GuC action types to inform GuC when Host has flushed the log buffer and forcefuly cause the GuC to send a new log buffer flush interrupt. v2: - Make documentation of log buffer state structure more elaborate & rename LOGBUFFERFLUSH action to LOG_BUFFER_FLUSH for consistency.(Tvrtko) v3: Add GuC log buffer layout diagram for more clarity.

2016-10-25drm/i915: Decouple GuC log setup from verbosity parameterSagar Arun Kamble
GuC Log buffer allocation was tied up with verbosity level module param i915.guc_log_level. User would be given a provision to enable firmware logging at runtime, through a host2guc action, and not necessarily during Driver load time. But the address of log buffer can be passed only in init params, at firmware load time, so GuC has to be reset and firmware needs to be reloaded to pass the log buffer address at runtime. To avoid reset of GuC & reload of firmware, allocation of log buffer will be done always but logging would be enabled initially on GuC side based on the value of module parameter guc_log_level. v2: Update commit message to describe the constraint with allocation of log buffer at runtime. (Tvrtko) v3: Rebase.

2016-10-24drm/i915/fbc: fix CFB size calculation for gen8+Paulo Zanoni
Broadwell and newer actually compress up to 2560 lines instead of 2048 (as documented in the FBC_CTL page). If we don't take this into consideration we end up reserving too little stolen memory for the CFB, so we may allocate something else (such as a ring) right after what we reserved, and the hardware will overwrite it with the contents of the CFB when FBC is active, causing GPU hangs. Another possibility is that the CFB may be allocated at the very end of the available space, so the CFB will overlap the reserved stolen area, leading to FIFO underruns. This bug has always been a problem on BDW (the only affected platform where FBC is enabled by default), but it's much easier to reproduce since the following commit: commit c58b735fc762e891481e92af7124b85cb0a51fce Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Aug 18 17:16:57 2016 +0100 drm/i915: Allocate rings from stolen Of course, you can only reproduce the bug if your screen is taller than 2048 lines.

2016-10-24drm/i915: Move fence cancellation to runtime suspendChris Wilson
At the moment, we have dependency on the RPM as a barrier itself in both i915_gem_release_all_mmaps() and i915_gem_restore_fences(). i915_gem_restore_fences() is also called along !runtime pm paths, but we can move the markup of lost fences alongside releasing the mmaps into a common i915_gem_runtime_suspend(). This has the advantage of locating all the tricky barrier dependencies into one location. v2: Just mark the fence as invalid (fence->dirty) so that upon waking we will be sure to clear the fence after use, or restore it to the correct value before use. This makes sure that if the fence is left intact across the sleep, we do not leave it pointing to a region of GTT for the next unsuspecting user.

2016-10-24drm/i915: Use RPM as the barrier for controlling user mmap accessChris Wilson
We can remove the false coupling between RPM and struct mutex by the observation that we can use the RPM wakeref as the barrier around user mmap access. That is as we tear down the user's PTE atomically from within rpm suspend and then to fault in new PTE requires the rpm wakeref, means that no user access is possible through those PTE without RPM being awake. Having made that observation, we can then remove the presumption of having to take rpm outside of struct_mutex and so allow fine grained acquisition of a wakeref around hw access rather than having to remember to acquire the wakeref early on. v2: Rejig placement of the new intel_runtime_pm_get() to be as tight as possible around the GTT pread/pwrite.

2016-10-24drm/i915: Move user fault tracking to a separate listChris Wilson
We want to decouple RPM and struct_mutex, but currently RPM has to walk the list of bound objects and remove userspace mmapping before we suspend (otherwise userspace may continue to access the GTT whilst it is powered down). This currently requires the struct_mutex to walk the bound_list, but if we move that to a separate list and lock we can take the first step towards removing the struct_mutex. v2: Split runtime suspend unmapping vs regular unmapping, to make the locking (and barriers) clearer. Add the object to the userfault_list prior to inserting the first PTE, the race between add/revoke depends upon struct_mutex for regular unmappings and rpm for runtime-suspend.

2016-10-21drm/i915: Use the per-plane rotation propertyVille Syrjälä
On certain platforms not all planes support the same set of rotations/reflections, so let's use the per-plane property for this. This is already a problem on SKL when we use the legay cursor plane as it only supports 0|180 whereas the universal planes support 0|90|180|270, and it will be a problem on CHV soon. v2: Use drm_plane_create_rotation_property() helper v3: Drop the BIT(), use INTEL_GEN() Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> (v1) Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1474907460-10717-12-git-send-email-ville.syrjala@linux.intel.com

2016-10-21drm/i915/dp: add lane_count check in intel_dp_check_link_statusMatthew Auld
Currently it's entirely possible to go through the link training step without first determining the lane_count, which is silly since we end up doing a bunch of aux transfers of size = 0, as highlighted by WARN_ON(!msg->buffer != !msg->size), and can only ever result in a 'failed to update link training' message. This can be observed during intel_dp_long_pulse where we can do the link training step, but before we have had a chance to set the link params. To avoid this we add an extra check for the lane_count in intel_dp_check_link_status, which should prevent us from doing the link training step prematurely. v2: add WARN_ON_ONCE and FIXME comment (Ville) References: https://bugs.freedesktop.org/show_bug.cgi?id=97344 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1476912593-10019-1-git-send-email-matthew.auld@intel.com Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com>

2016-10-21drm/i915: Respect alternate_ddc_pin for all DDI portsVille Syrjälä
The VBT provides the platform a way to mix and match the DDI ports vs. GMBUS pins. Currently we only trust the VBT for DDI E, which I suppose has no standard GMBUS pin assignment. However, there are machines out there that use a non-standard mapping for the other ports as well. Let's start trusting the VBT on this one for all ports on DDI platforms. I've structured the code such that other platforms could easily start using this as well, by simply filling in the ddi_port_info.

2016-10-21drm/i915: Respect alternate_aux_channel for all DDI portsVille Syrjälä
The VBT provides the platform a way to mix and match the DDI ports vs. AUX channels. Currently we only trust the VBT for DDI E, which has no corresponding AUX channel of its own. However it is possible that some board might use some non-standard DDI vs. AUX port routing even for the other ports. Perhaps for signal routing reasons or something, So let's generalize this and trust the VBT for all ports. For now we'll limit this to DDI platforms, as we trust the VBT a bit more there anyway when it comes to the DDI ports. I've structured the code in a way that would allow us to easily expand this to other platforms as well, by simply filling in the ddi_port_info. v2: Drop whitespace changes, keep MISSING_CASE() for unknown aux ch assignment, include a commit message, include debug message during init Cc: stable@vger.kernel.org Cc: Maarten Maathuis <madman2003@gmail.com> Tested-by: Maarten Maathuis <madman2003@gmail.com> References: https://bugs.freedesktop.org/show_bug.cgi?id=97877 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1476208368-5710-2-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Jim Bride <jim.bride@linux.intel.com>
