2020-05-14drm/i915/psr: Use new DP VSC SDP compute routine on PSRGwan-gyeong Mun
In order to use a common VSC SDP Colorimetry calculating code on PSR, it uses a new psr vsc sdp compute routine. Because PSR routine has its own scenario and timings of writing a VSC SDP, the current PSR routine needs to have its own drm_dp_vsc_sdp structure member variable on struct i915_psr. In order to calculate colorimetry information, intel_psr_update() function and intel_psr_enable() function extend a drm_connector_state argument. There are no changes to PSR mechanism. v3: Replace a structure name to drm_dp_vsc_sdp from intel_dp_vsc_sdp v4: Rebased v8: Rebased v10: When a PSR is enabled, it needs to add DP_SDP_VSC to infoframes.enable.

2020-05-14drm/i915: Fix enabled infoframe states of lspconGwan-gyeong Mun
Compared to implementation of DP and HDMI's encoder->infoframes_enabled, the lspcon's implementation returns its active state. (we expect enabled infoframe states of HW.) It leads to pipe state mismatch error when ddi_get_config is called. Because the current implementation of lspcon is not ready to support readout infoframes, we need to return 0 here. In order to support readout to lspcon, we need to implement read_infoframe and infoframes_enabled. And set_infoframes also have to set an appropriate bit on crtc_state->infoframes.enable Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200514060732.3378396-11-gwan-gyeong.mun@intel.com

2020-05-14video/hdmi: Add Unpack only function for DRM infoframeGwan-gyeong Mun
It adds an unpack only function for DRM infoframe for dynamic range and mastering infoframe readout. It unpacks the information data block contained in the binary buffer into a structured frame of the HDMI Dynamic Range and Mastering (DRM) information frame. In contrast to hdmi_drm_infoframe_unpack() function, it does not verify a checksum. It can be used for unpacking a DP HDR Metadata Infoframe SDP case. DP HDR Metadata Infoframe SDP uses the same Dynamic Range and Mastering (DRM) information (CTA-861-G spec.) such as HDMI DRM infoframe. But DP SDP header and payload structure are different from HDMI DRM Infoframe. Therefore unpacking DRM infoframe for DP requires skipping of a verifying checksum. v9: Add clear comments to hdmi_drm_infoframe_unpack_only() and hdmi_drm_infoframe_unpack() (Laurent Pinchart) Signed-off-by: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200514060732.3378396-2-gwan-gyeong.mun@intel.com
2020-05-14drm/i915/gt: Transfer old virtual breadcrumbs to irq_workerChris Wilson
The second try at staging the transfer of the breadcrumb. In part one, we realised we could not simply move to the second engine as we were only holding the breadcrumb lock on the first. So in commit 6c81e21a4742 ("drm/i915/gt: Stage the transfer of the virtual breadcrumb"), we removed it from the first engine and marked up this request to reattach the signaling on the new engine. However, this failed to take into account that we only attach the breadcrumb if the new request is added at the start of the queue, which if we are transferring, it is because we know there to be a request to be signaled (and hence we would not be attached). In this attempt, we try to transfer the completed requests to the irq_worker on its rq->engine->breadcrumbs. This preserves the coupling between the rq and its breadcrumbs, so that i915_request_cancel_breadcrumb() does not attempt to manipulate the list under the wrong lock. v2: Code sharing is fun.

2020-05-13drm/i915/gt: Suspend tasklets before resume sanitizationChris Wilson
It is possible for a residual tasklet to be pending execution as we resume (whether that's some prior test kicking off the tasklet, or if we are in a suspend/resume stress test). As such, we do not want that tasklet to execute in the middle of our sanitization, such that it sees the poisoned state.

2020-05-12drm/i915: Handle idling during i915_gem_evict_something busy loopsChris Wilson
i915_gem_evict_something() is charged with finding a slot within the GTT that we may reuse. Since our goal is not to stall, we first look for a slot that only overlaps idle vma. To this end, on the first pass we move any active vma to the end of the search list. However, we only stopped moving active vma after we see the first active vma twice. If during the search, that first active vma completed, we would not notice and keep on extending the search list.
