drm/i915: Stop doing double audio enable/disable on SDVO and g4x+ DP Looks like I misplaced a few hunks when I moved the audio enable/disable out from the encoder enable/disable hooks. So we are now doing a double audio enable/disable on SDVO and g4x+ DP. Probably harmless as doing it twice shouldn't really change anything, but let's do it just once, as intended.

drm/i915: Remove AUX CH sanitation Stop with the VBT AUX CH sanitation, and instead just check that the appropriate AUX CH is still available when initializing a DP/TC port. The reason being that we want to start initializing ports in VBT order to deal with VBTs that declare child devices with seemingly conflicting ports. As the encoder initialization can fail for other reasons (at least for eDP+AUX) we can't know upfront which way the conflicts should be resolved. Note that the old way of sanitizing gave priority to the last port declared in the VBT, but now we sort of do the opposite by favoring the first encoder to successfully initialize. The reason for the old "last port wins" preference was eg. Asrock B250M-HDV where port A (eDP) and port E (DP->VGA) have an AUX CH conflict and we need to prefer port E. However with the new way port A (eDP) will be probed first, but will fail to probe due to HPD and thus port E will still win in the end. v2: Pimp the commit message (Jani) Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230630155846.29931-5-ville.syrjala@linux.intel.com

drm/i915: Get rid of the gm45 HPD live state nonsense The idea that ctg uses different HPD live state bits is total nonsense, at least on my machine (Dell Latitude E5400). The only reason DP-B even works on my ctg is that DP-D live state is stuck high, even though there is no physical DP-D port. So when the detect checks DP-B live state it sees the stuck live state of DP-D instead. If I hack the driver to not register DP-D at all, and thus we never enabe DP-D HPD, DP-B stops working as well. Just to put some conclusive evidence into this mess, here are the actual hotplug register values for each port: Everything disconnected: PORT_HOTPLUG_EN (0x00061110): 0x00000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x08000000 PORT_HOTPLUG_STAT (0x00061114): 0x08000000 PORT_HOTPLUG_EN (0x00061110): 0x10000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x20000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 Only port B connected: PORT_HOTPLUG_EN (0x00061110): 0x00000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x08000000 PORT_HOTPLUG_STAT (0x00061114): 0x08000000 PORT_HOTPLUG_EN (0x00061110): 0x10000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x20000000 PORT_HOTPLUG_STAT (0x00061114): 0x20000000 Only port C connected: PORT_HOTPLUG_EN (0x00061110): 0x00000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x08000000 PORT_HOTPLUG_STAT (0x00061114): 0x08000000 PORT_HOTPLUG_EN (0x00061110): 0x10000000 PORT_HOTPLUG_STAT (0x00061114): 0x10000000 PORT_HOTPLUG_EN (0x00061110): 0x20000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 So the enable bit and live state bit always match 1:1.

drm/i915: stop including i915_irq.h from i915_trace.h Turns out many of the files that need i915_reg.h get it implicitly via {display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h -> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h, makes sense to drop it, but that requires adding quite a few new includes all over the place. Prefer including i915_reg.h where needed instead of adding another implicit include, because eventually we'll want to split up i915_reg.h and only include the specific registers at each place.

drm/i915/trace: split out display trace to a separate file Add display/intel_display_trace.[ch] for defining display tracepoints. The main goal is to reduce cross-includes between gem and display. It would be possible split up tracing even further, but that would lead to more boilerplate. We end up having to include intel_crtc.h in a few places because it was pulled in implicitly via intel_de.h -> i915_trace.h -> intel_crtc.h, and that's no longer the case. There should be no changes to tracepoints. v3: - Rebase v2: - Define TRACE_INCLUDE_PATH relative to define_trace.h (Chris) - Remove useless comments (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/7862ad764fbd0748d903c76bc632d3d277874e5b.1638961423.git.jani.nikula@intel.com

drm/i915: Generalize .set_signal_levels() Currently .set_signal_levels() is only used by encoders in DP mode. For most modern platforms there is no essential difference between DP and HDMI, and both codepaths just end up calling the same function under the hood. Let's get remove the need for that extra indirection by moving .set_signal_levels() into the encoder from intel_dp. Since we already plumb the crtc_state/etc. into .set_signal_levels() the code will do the right thing for both DP and HDMI. HSW/BDW/SKL are the only platforms that need a bit of care on account of having to preload the hardware buf_trans register with the full set of values. So we must still remember to call hsw_prepare_{dp,hdmi}_ddi_buffers() to do said preloading, and .set_signal_levels() will just end up selecting the correct entry for DP, and also setting up the iboost magic for both DP and HDMI. Note that previously on HSW/BDW/SKL we did write to DDI_BUF_CTL to select the correct entry until link training started, now that we call .set_signal_levels() already from hsw_ddi_pre_enable_dp() that is no longer the case. But it's all safe now that the intel_ddi_init_dp_buf_reg() call was hoisted up and it no longer sets up the DDI_BUF_CTL_ENABLE bit (that is still deferred until link training). v2: Rebase due to has_{iboost,buf_trans_select}() Add some notes about the DDI_BUF_CTL situation on HSW/BDW/SKL (Imre) Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211001130107.1746-4-ville.syrjala@linux.intel.com

drm/i915: s/pipe/transcoder/ when dealing with PIPECONF/TRANSCONF PIPECONF becamse TRANSCONF when HSW introduced the EDP transcoder. Bigjoiner is making life even more confusing by introducing a N:1 relationship between pipes and transcoders. In that case we only enable/configure the transcoder corresponding to the master pipe. Let's do some renames to make it clear we're dealing with the transcoder rather than pipe when it comes to PIPECONF/TRANSCONF. I decided to leave the _cpu_ part out from the function/macro names since the PCH transcoder related stuff already has a _pch_ in their name. So shouldn't be possible to confuse them.
