2020-04-21drm/i915/audio: fix compressed_bpp checkJani Nikula
The early check for compressed_bpp being zero is too early, as it is hit also when DSC is not enabled. Move the checks down to where the values are actually needed. This is a paranoid check for a situation that should not happen, so we don't really care about handling it gracefully apart from not oopsing.

2020-04-20drm/i915: Use single set of AUX powerwell ops for gen11+Matt Roper
AUX power wells sometimes need additional handling besides just programming the specific power well registers: * Type-C PHY's also require additional Type-C register programming * ICL combo PHY's require additional workarounds * TGL & EHL combo PHY's can be treated like any other power well Today we have dedicated aux ops for the ICL combo PHY and Type-C cases. This works fine, but means that when a new platform shows up with identical general power well handling, but different types of PHYs on its outputs, we have to define an entire new power well table for that platform and can't just re-use the table from the earlier platform -- as an example, see ehl_power_wells[], which is a subset of icl_power_wells[], *except* that we need to specify different AUX ops for the third display. If we instead create a single set of top-level aux ops that will check the PHY type and then dispatch to the appropriate handlers, we can get more reuse out of our power well definitions. This allows us to immediately eliminate ehl_power_wells[] and simply reuse the ICL table; if future platforms follow the same general power well assignments as either ICL or TGL, we'll be able to re-use those tables in the same way. Note that I've only changed ICL+ platforms over to using the new icl_aux ops; at this point it's unlikely that we'll have any new platforms that re-use gen9 or earlier power well configurations. v2: - ICL_AUX_PW_TO_PHY() won't return the proper PHY for TBT AUX power wells. But we know those wells will only used on Type-C outputs anyway, so we can just check is is_tc_tbt flag in the condition. (Jose).

2020-04-20drm/i915: Push MST link retraining to the hotplug workVille Syrjälä
We shouldn't try to do link retraining from the short hpd handler. We can't take any modeset locks there so this is racy as hell. Push the whole thing into the hotplug work like we do with SST. We'll just have to adjust the SST retraining code to deal with the MST encoders and multiple pipes. TODO: I have a feeling we should just rip this all out and do a full modeset instead. Stuff like port sync and the tgl+ MST master transcoder stuff maybe doesn't work well if we try to retrain without following the proper modeset sequence. So far haven't done any actual tests to confirm that though.

2020-04-17drm/i915/display: Load DP_TP_CTL/STATUS offset before use itJosé Roberto de Souza
Right now dp.regs.dp_tp_ctl/status are only set during the encoder pre_enable() hook, what is causing all reads and writes to those registers to go to offset 0x0 before pre_enable() is executed. So if i915 takes the BIOS state and don't do a modeset any following link retraing will fail. In the case that i915 needs to do a modeset, the DDI disable sequence will write to a wrong register not disabling DP 'Transport Enable' in DP_TP_CTL, making a HDMI modeset in the same port/transcoder to not light up the monitor. So here for GENs older than 12, that have those registers fixed at port offset range it is loading at encoder/port init while for GEN12 it will keep setting it at encoder pre_enable() and during HW state readout.

2020-04-17drm/i915/tc/icl: Implement TC cold sequencesJosé Roberto de Souza
This is required for legacy/static TC ports as IOM is not aware of the connection and will not trigger the TC cold exit. Just request PCODE to exit TCCOLD is not enough as it could enter again before driver makes use of the port, to prevent it BSpec states that aux powerwell should be held. So here embedding the TC cold exit sequence into ICL aux enable, it will enable aux and then request TC cold to exit. The TC cold block(exit and aux hold) and unblock was added to some exported TC functions for the others and to access PHY registers, callers should enable and keep aux powerwell enabled during access. Also adding TC cold check and warnig in tc_port_load_fia_params() as at this point of the driver initialization we can't request power wells, if we get this warning we will need to figure out how to handle it. v2: - moved ICL TC cold exit function to intel_display_power - using dig_port->tc_legacy_port to only execute sequences for legacy ports, hopefully VBTs will have this right - fixed check to call _hsw_power_well_continue_enable() - calling _hsw_power_well_continue_enable() unconditionally in icl_tc_phy_aux_power_well_enable(), if needed we will surpress timeout warnings of TC legacy ports - only blocking TC cold around fia access v3: - added timeout of 5msec to not loop forever if sandybridge_pcode_write_timeout() keeps returning -EAGAIN returning -EAGAIN in in icl_tc_cold_exit() - removed leftover tc_cold_wakeref - added one msec sleep when PCODE returns -EAGAIN v4: - removed 5msec timeout, instead giving 1msec to whoever is using PCODE to finish it up to 3 times - added a comment about turn TC cold exit failure as a error in future BSpec: 21750 Closes: https://gitlab.freedesktop.org/drm/intel/issues/1296 Cc: Imre Deak <imre.deak@intel.com> Cc: Cooper Chiou <cooper.chiou@intel.com> Cc: Kai-Heng Feng <kai.heng.feng@canonical.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200414194956.164323-4-jose.souza@intel.com

Current "standard" way of doing this in commit_tail is pre/post plane updates, when everything which has to be forbidden and not supported in new config has to be restricted before update and relaxed after plane update. v2: - Removed unneeded returns(Ville) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200415143911.10244-5-stanislav.lisovskiy@intel.com

Add correspondent helpers to be able to get old/new bandwidth global state object. v2: - Fixed typo in function call v3: - Changed new functions naming to use convention proposed by Jani Nikula, i.e intel_bw_* in intel_bw.c file. v4: - Change function naming back to intel_atomic* pattern, was decided to rename in a separate patch series. v5: - Fix function naming to match existing practices(Ville) v6: - Removed spurious whitespace v7: - Removed bw_state NULL checks(Ville) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200415143911.10244-3-stanislav.lisovskiy@intel.com
2020-04-17drm/i915/display: Enable DP Display Audio WAUma Shankar
For certain DP VDSC bpp settings, hblank asserts before hblank_early, leading to a bad audio state. Driver need to program "hblank early enable" and "samples per line" parameters in AUDIO_CONFIG_BE register. This is Display Audio WA #1406928334 for 4k+VDSC usecase applicable on DP encoders. Implemented the same. v2: Fixed build failures on 32bit machine. v3: Dropped u64, added helpers for sample room calculation, other general comments as per Jani Nikula's feedback. Also fixed connector type check (spotted by Anshuman) v4: Addressed Jani Nikula and Kai's review comments. v5: Addressed Anshuman's review comment and used crtc_* variable to get timings. v6: Dropped a redundant initialization.

2020-04-17drm/i915: Add i915_lpsp_capability debugfsAnshuman Gupta
New i915_pm_lpsp igt solution approach relies on connector specific debugfs attribute i915_lpsp_capability, it exposes whether an output is capable of driving lpsp. v2: - CI fixup. v3: - register i915_lpsp_info only for supported connector. [Jani] - use intel_display_power_well_is_enabled() instead of looking inside power_well count. [Jani] - fixes the lpsp capable conditional logic. [Jani] - combined the lpsp capable and enable info.

2020-04-14drm/i915: do AUD_FREQ_CNTRL state save on all gen9+ platformsKai Vehmanen
Replace the TGL/ICL specific platform checks with a more generic check using INTEL_GEN(). Fixes bug with broken audio after S3 resume on JSL platforms. An initial version of state save and restore of AUD_FREQ_CNTRL register was added for subset of platforms in commit 87c1694533c9 ("drm/i915: save AUD_FREQ_CNTRL state at audio domain suspend"). The state save has proven to work well and it is needed in newer platforms, so needs to be extended. Although the logic is not in practise needed on GEN9/10 systems, follow the hardware specification and apply state and restore on all gen9+ platforms.
