Doing any kind modeset stuff from the short hpd handler is verboten. The ad-hoc PHY test modeset code violates this. And by calling various link training related functions it's now blocking further work to plumb the crtc state down into the link training code. Let's hack around that by pushing the PHY test stuff into the hotplug work where it's less of a problem. Still not great but at least acceptable. We take a few pages from the link retraining handbook to handle the locking and whatnot. v2: Fix the intel_dp_hotplug() return value Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200930100412.9313-1-ville.syrjala@linux.intel.comReviewed-by: Imre Deak <imre.deak@intel.com>

The HDMI vs. not-HDMI check got inverted whem the bogus encoder->type checks were eliminated. So now we're using 0 as the link rate on DP and potentially non-zero on HDMI, which is exactly the opposite of what we want. The original bogus check actually worked more correctly by accident since if would always evaluate to true. Due to this we now always use the RBR/HBR1 vswing table and never ever the HBR2+ vswing table. That is probably not a good way to get a high quality signal at HBR2+ rates. Fix the check so we pick the right table.

In case of DSI cmd mode, we get hw vblank counter updated after the TE comes in, if we try to read the hw vblank counter in te handler we wouldnt have the udpated vblank counter yet. This will lead to a state where we would send the vblank event to the user space in the next te, though the frame update would have completed in the first TE duration itself. Hence switch to using software timestamp based vblank counter. v2: Use mode_flags from crtc_state (Ville) Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Vandita Kulkarni <vandita.kulkarni@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200924124209.17916-6-vandita.kulkarni@intel.com

In TE Gate mode or TE NO_GATE mode on every flip we need to set the frame update request bit.

In case of dual link, we get the TE on slave. So clear the TE on slave DSI IIR. If we are operating in TE_GATE mode, after we do a frame update, the transcoder will send the frame data to the panel, after it receives a TE. Whereas if we are operating in NO_GATE mode then the transcoder will immediately send the frame data to the panel.

Previously intel_dump_pipe_config() used to dump the full crtc state whether or not the crtc was logically enabled or not. As that meant occasionally dumping confusing stale garbage I changed it to check whether the crtc is logically enabled or not. However I did not realize that the state checker readout code does not populate crtc_state.hw.{active,enabled}. Hence the state checker dump would only give us a full dump of the sw state but not the hw state. Fix that by populating those bits of the hw state as well.

When validating a "YCbCr 4:2:0 only" mode we must take into account the fact that we're going to be outputting YCbCr 4:2:0 or 4:4:4 (when a DP->HDMI protocol converter is doing the 4:2:0 downsampling). For YCbCr 4:4:4 the minimum output bpc is 8, for YCbCr 4:2:0 it'll be half that. The currently hardcoded 6bpc is only correct for RGB 4:4:4, which we will never use with these kinds of modes. Figure out what we're going to output and use the correct min bpp value to validate whether the link has sufficient bandwidth.

When roll over detected for seq_num_m, we shouldn't continue with stream management with rolled over value. So we are terminating the stream management retry, on roll over of the seq_num_m. v2: using drm_dbg_kms instead of DRM_DEBUG_KMS [Anshuman] v3: dev_priv is used as i915 [JaniN] v4: roll over is detected at the start of the stream management.

As per the HDCP2.2 compliance test 1B-10 expectation, when stream management for a repeater fails, we retry thrice and when it fails in all retries, HDCP2.2 reauthentication aborted at kernel. v2: seq_num_m++ is extended for steam management failures too.[Anshuman] v3: use drm_dbg_kms instead of DRM_DEBUG_KMS [Anshuman] v4: dev_priv is used as i915 [JaniN] v5: Few improvisements are done [Sean] Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Tested-by: Anshuman Gupta <anshuman.gupta@intel.com> Reviewed-by: Anshuman Gupta <anshuman.gupta@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200923132435.17039-2-anshuman.gupta@intel.com
