(This patch is developed by Dave Airlie <airlied@redhat.com> originally) This patch adds support for DP MST audio in i915. Enable audio codec when DP MST is enabled if has_audio flag is set. Disable audio codec when DP MST is disabled if has_audio flag is set. Another separated patches to support DP MST audio will be implemented in audio driver. v2: Rebased.

With DP MST, a digital_port can carry more than one audio stream. Hence, more than one audio_connector needs to be attached to intel_digital_port in such cases. However, each stream is associated with an unique encoder. So, instead of creating an array of audio_connectors per port, move audio_connector from struct intel_digital_port to struct intel_encoder. This also simplifies access to the right audio_connector from codec functions in intel_audio.c that receive intel_encoder. v2: Removed locals that are not needed anymore. v3: No code change except for minor change in context.

Storing the port enum in intel_encoder makes it convenient to know the port attached to an encoder. Moving the port information up from intel_digital_port to intel_encoder avoids unecessary intel_digital_port access and handles MST encoders cleanly without requiring conditional checks for them (thanks danvet). v2: Renamed the port enum member from 'attached_port' to 'port' (danvet) Fixed missing initialization of port in intel_sdvo.c (danvet) v3: Fixed missing initialization of port in intel_crt.c (Ville) v4: Storing port for DVO encoders too.

There is a disparity in the context image saved to disk and our own bookkeeping - that is we presume the RING_HEAD and RING_TAIL match our stored ce->ring->tail value. However, as we emit WA_TAIL_DWORDS into the ring but may not tell the GPU about them, the GPU may be lagging behind our bookkeeping. Upon hibernation we do not save stolen pages, presuming that their contents are volatile. This means that although we start writing into the ring at tail, the GPU starts executing from its HEAD and there may be some garbage in between and so the GPU promptly hangs upon resume.

由 Imre Deak 提交于
While user space has control over the scheduling priority of its page flipping thread, the corresponding work the driver schedules for MMIO flips always runs from the generic system workqueue which has some scheduling overhead due it being CPU bound. This would hinder an application that wants more stringent guarantees over flip timing (to avoid missing a flip at the next frame count). Fix this by scheduling the work from the unbound system workqueue which provides for minimal scheduling latency. v2: - Use an unbound workqueue instead of a high-prio one. (Tvrtko, Chris) v3: - Use the system unbound wq instead of a dedicated one.

Filter out a mode that exceeds the max pixel rate setting for DP to VGA dongle. This is defined in DPCD register 0x81 if detailed cap info i.e. info field is 4 bytes long and it is available for DP downstream port. The register defines the pixel rate divided by 8 in MP/s. v2: DPCD read outs and computation moved to drm (Ville, Daniel) v3: Sink pixel rate computation moved to drm_dp_max_sink_dotclock() function (Daniel) v4: Use of drm_dp_helper.c routines to compute max pixel clock (Ville) v5: Use of intel_dp->downstream_ports to read out port capabilities. Code restructuring (Ville) v6: Move DP branch device check to drm_dp_helper.c (Daniel) v7: Cleanup as suggested by Ville Reviewed-by: NJim Bride <jim.bride@linux.intel.com> Signed-off-by: NMika Kahola <mika.kahola@intel.com> Signed-off-by: NJani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1473419458-17080-10-git-send-email-mika.kahola@intel.com
