Having taken the first step in encapsulating the functionality by moving the related files under gt/, the next step is to start encapsulating by passing around the relevant structs rather than the global drm_i915_private. In this step, we pass intel_gt to intel_reset.c Signed-off-by:

Some platforms may have Modular FIA. If Modular FIA is used in the SOC, then Display Driver will access the additional instances of FIA based on pre-assigned offset in GTTMADDR space. Each Modular FIA instance has its own IOSF Sideband Port ID and it houses only 2 Type-C Port. In SOC that has more than two Type-C Ports, there are multiple instances of Modular FIA. Gunit will need to use different destination ID when it access different pair of Type-C Port. The DFLEXDPSP register has Modular FIA bit starting on Tiger Lake. If Modular FIA is used in the SOC, this register bit exists in all the instances of Modular FIA. IOM FW is required to program only the MF bit in first FIA instance that houses the Type-C Port 0 and Port 1, for Display Driver to read from. v2 (Lucas): - Move all accesses to FIA to be contained in intel_tc.c, along with display_fia that is now called tc_phy_fia - Save the fia instance number on intel_digital_port, so we don't have to query if modular FIA is used on every access v3 (Lucas): Make function static v4 (Lucas): Move enum phy_fia to the header and use it in intel_digital_port (suggested by Ville) v5 (Lucas): Add comment about the mapping between FIA and TC port (suggested by Stuart) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by:Anusha Srivatsa <anusha.srivatsa@intel.com> Signed-off-by:

With an explicit level, we can refactor the separate clear functions as a simple recursive function. The additional knowledge of the level allows us to spot when we can free an entire subtree at once. Signed-off-by:

intel_atomic_commit() is not for use internally, but only as an entry point from the core drm atomic helper (drm_atomic_commit).

CH7511 doesn't update SINK_COUNT properly so in order to detect the device as connected we have to ignore SINK_COUNT. In order to have access to the quirk list early enough we must move the drm_dp_read_desc() call to happen earlier. We can also skip re-reading this on eDP since we know it won't change.

Using "enable_guc" modparam auto mode (-1) will let driver decide on which platforms and in which configuration we want to use GuC/HuC firmwares. Today driver will enable HuC firmware authentication by GuC only on Gen11+ platforms as HuC firmware is required to unlock advanced video codecs in media driver. Legacy platforms with GuC/HuC are not affected by this change as for them driver still defaults to disabled(0) in auto mode. Signed-off-by:

We are about to change default setting of "enable_guc" modparam from 0(disabled) to -1(auto). As we only want to turn on GuC/HuC on Gen11+, keep it off for older gens. Note that it would be still possible to enable GuC/HuC on these old platforms using explicit "enable_guc=2" modparam. Signed-off-by:

Replace mixed "_fini"/"_cleanup"/"_cleanup_hw" suffixes found in names of functions called from i915_driver_release() with "_release" suffix consistently. This provides better code readability, especially helpful when trying to work out which phase the code is in. Functions names starting with "i915_driver_", i.e., those defined in drivers/gpu/dri/i915/i915_drv.c, just have their "cleanup" or "fini" parts of their names replaced with the "_release" suffix, while names of functions coming from other source files have been suffixed with "_driver_release" to avoid ambiguity with other possible .release entry points. v2: early_probe pairs better with late_release (Chris) v3: fix typo in commit message (Joonas) Suggested-by:

There is a debug message in the workaround initialisation path that reports how many entries were added of each type. However, whitelist workarounds exist for multiple engines but the type name is just 'whitelist'.

Make the icl function generic so it is based on phy type and can be applied to tgl as well. I checked if this could not apply to EHL as well, but unfortunately there the HPD and DDC/GMBUS pins for DDI C are mapped to TypeC Port 1 even though it doesn't have TC phy. v2: don't add a separate function for TGL, but rather reuse the ICL one (suggested by Rodrigo) v3: rebase after the introduction of enum phy and use it for the conversions Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190711173115.28296-19-lucas.demarchi@intel.com

The patch adds the new power wells introduced by TGL (GEN 12) and maps these to existing/new power domains. The changes for GEN 12 wrt to GEN 11 are the following: - Transcoder#EDP removed from power well#1 (Transcoder#A used in low-power mode instead) - Transcoder#A is now backed by power well#1 instead of power well#3 - The DDI#B/C combo PHY ports are now backed by power well#1 instead of power well#3 - New power well#5 added for pipe#D functionality (TODO) - 2 additional TC ports (TC#5-6) backed by power well#3, 2 port specific IO power wells (only for the non-TBT modes) and 4 port specific AUX power wells (2-2 for TBT vs. non-TBT modes) - Power well#2 backs now VDSC/joining for pipe#A instead of VDSC for eDP and MIPI DSI (TODO) On TGL Port DDI#C changed to be a combo PHY (native DP/HDMI) and BSpec has renamed ports DDI#D-F to TC#4-6 respectively. Thus on ICL we have the following naming for ports: - Combo PHYs (native DP/HDMI): DDI#A-B - TBT/non-TBT (TC altmode, native DP/HDMI) PHYs: DDI#C-F Starting from GEN 12 we have the following naming for ports: - Combo PHYs (native DP/HDMI): DDI#A-C - TBT/non-TBT (TC altmode, native DP/HDMI) PHYs: DDI TC#1-6 To save some space in the power domain enum the power domain naming in the driver reflects the above change, that is power domains TC#1-3 are added as aliases for DDI#D-F and new power domains are reserved for TC#4-6. v2 (Lucas): - Separate out the bits and definitions for TGL from the ICL ones. Fix use of TRANSCODER_EDP_VDSC, that is now the correct define since we don't define TRANSCODER_A_VDSC power domain to spare a one bit in the bitmask (suggested by Ville) v3 (Lucas): - Fix missing squashes on v2 - Rebase on renamed TRANSCODER_EDP_VDSC Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:Imre Deak <imre.deak@intel.com> Signed-off-by:
