      drm/i915/icl: Add fallback detection method for TypeC legacy ports · 2a041c97
      Imre Deak authored
      Add a fallback detection method for TypeC legacy ports in case the
      VBT port information used to detect normally such ports is
      incorrect.
      
      For the fallback method we use the TypeC legacy mode specific HPD
      interrupt flag which should only be raised for a legacy port.
      
      WARN if the VBT port info is incorrect.
      
      In a case where we'd detect the port in a contradicting way both as a
      legacy and also as a USB DP and/or TBT alternate port treat the port
      as legacy (by also emitting a WARN from icl_update_tc_port_type).
      
      v2:
      - Repurpose the detection as a fallback method instead of using
        it only for the DP legacy case. By now we should normally use VBT to
        detect DP legacy ports as well.

      drm/i915/icl: Fix HPD handling for TypeC legacy ports · f6bff60e
      Imre Deak authored
      Atm HPD disconnect events on TypeC ports will break things, since we'll
      switch the TypeC mode (between legacy and disconnected modes as well as
      among USB DP alternate, Thunderbolt alternate and disconnected modes) on
      the fly from the HPD disconnect interrupt work while the port may be
      still active.
      
      Even if the port happens to be not active during the disconnect we'd
      still have a problem during a subsequent modeset or AUX transfer that
      could happen regardless of the port's connected state. For instance the
      system resume display mode restore code and userspace could perform a
      modeset on the port or userspace could start an AUX transfer even if the
      port is in disconnected state.
      
      To fix this keep TypeC legacy ports in legacy mode whenever we're not
      suspended. This mode is a static configuration as opposed to the
      Thunderbolt and USB DP alternate modes between which we can switch
      dynamically.
      
      We determine if a TypeC port is legacy (wired to a legacy HDMI or a
      legacy DP connector) via the VBT DDI port specific USB-TypeC and
      Thunderbolt flags. If both these flags are cleared then the port is
      configured for legacy mode.
      
      On such legacy ports we'll run the TypeC PHY connect sequence explicitly
      during driver loading and system resume (vs. running the sequence during
      HPD processing). The connect will succeed even if the display is not
      connected to begin with (or disappears during the suspended state) since
      for legacy ports the PORT_TX_DFLEXDPPMS / DP_PHY_MODE_STATUS_COMPLETED
      flag is always set (as opposed to the USB DP alternate mode where it
      gets set only when a display is connected).
      
      Correspondingly run the TypeC PHY disconnect sequence during system
      suspend and driver unloading. For the unloading case I had to split
      up intel_dp_encoder_destroy() to be able to have the 1. flush any
      pending encoder work, 2. disconnect TC PHY, 3. call DRM core cleanup and
      kfree on the encoder object.
      
      For now run the PHY disconnect during suspend only for TypeC legacy
      ports. We will need to disconnect even in USB DP alternate mode in the
      future, but atm we don't have a way to reconnect the port in this mode
      during resume if the display disappears while being suspended. So for
      now punt on this case.
      
      Note that we do not disconnect the port during runtime suspend; in
      legacy mode there are no shared HW resources (PHY lanes) with other HW
      blocks (USB), so no need to release / reacquire these resources as with
      USB DP alternate mode. The only reason to disconnect legacy ports during
      system suspend is that the PORT_TX_DFLEXDPPMS /
      DP_PHY_MODE_STATUS_COMPLETED flag must be rechecked and the port must be
      connected again during system resume. We'll also have to turn the check
      for this flag into a poll, after figuring out what's the proper timeout
      value for it.
      
      v2:
      - Remove the redundant special casing of legacy mode when doing a
        disconnect in icl_tc_port_connected(). It's guaranteed already that we
        won't disconnect legacy ports in that function.
      - Add a note about the new intel_ddi_encoder_destroy() hook.
      - Reword the commit message after switching to the VBT based detection.

      drm/i915: Apply missed interrupt after reset w/a to all ringbuffer gen · 060f2322
      Chris Wilson authored
      Having completed a test run of gem_eio across all machines in CI we also
      observe the phenomenon (of lost interrupts after resetting the GPU) on
      gen3 machines as well as the previously sighted gen6/gen7. Let's apply
      the same HWSTAM workaround that was effective for gen6+ for all, as
      although we haven't seen the same failure on gen4/5 it seems prudent to
      keep the code the same.
      
      As a consequence we can remove the extra setting of HWSTAM and apply the
      register from a single site.
      
      v2: Delazy and move the HWSTAM into its own function
      v3: Mask off all HWSP writes on driver unload and engine cleanup.
      v4: And what about the physical hwsp?
      v5: No, engine->init_hw() is not called from driver_init_hw(), don't be
      daft. Really scrub HWSTAM as early as we can in driver_init_mmio()
      v6: Rename set_hwsp as it was setting the mask not the hwsp register.
      v7: Ville pointed out that although vcs(bsd) was introduced for g4x/ilk,
      per-engine HWSTAM was not introduced until gen6!

      drm/i915: Update crtc scaler settings when update_pipe is set · 2c5c415c
      Hans de Goede authored
      When the pipe_config's update_pipe flag is set we may need to update the
      panel fitting settings. On GEN9+ this means we need to update the crtc's
      scaler settings.
      
      This fixes the following WARN_ON, during i915 loading on an Asrock
      B150M Pro4S/D3 board with an i5-6500 CPU / graphics:
      
      [drm:pipe_config_err [i915]] *ERROR* mismatch in pch_pfit.enabled
       (expected no, found yes)
      pipe state doesn't match!
      WARNING: CPU: 3 PID: 305 at drivers/gpu/drm/i915/intel_display.c:12084
      
      With line 12084 being the I915_STATE_WARN call inside the
      "if (!intel_pipe_config_compare())" block in verify_crtc_state().
      
      On this board with 2 1920x1080 monitors connected over HDMI the GOP
      initializes both monitors at 1920x1080 and despite no scaling being
      necessary configures a scaler for one of them.
      
      When booting with fastboot=1 on the initial modeset needs_modeset will
      be false while update_pipe is true. Since we were not calling
      skl_update_scaler_crtc() in this case we would leave the scaler enabled
      causing this error.

      drm/i915/icl: Mind the SFC units when resetting VD or VEBox engines · f513ac76
      Oscar Mateo authored
      SFC (Scaler & Format Converter) units are shared between VD and VEBoxes.
      They also happen to have separate reset bits. So, whenever we want to reset
      one or more of the media engines, we have to make sure the SFCs do not
      change owner in the process and, if this owner happens to be one of the
      engines being reset, we need to reset the SFC as well.
      
      This happens in 4 steps:
      
      1) Tell the engine that a software reset is going to happen. The engine
      will then try to force lock the SFC (if currently locked, it will
      remain so; if currently unlocked, it will ignore this and all new lock
      requests).
      
      2) Poll the ack bit to make sure the hardware has received the forced
      lock from the driver. Once this bit is set, it indicates SFC status
      (lock or unlock) will not change anymore (until we tell the engine it
      is safe to unlock again).
      
      3) Check the usage bit to see if the SFC has ended up being locked to
      the engine we want to reset. If this is the case, we have to reset
      the SFC as well.
      
      4) Unlock all the SFCs once the reset sequence is completed.
      
      Obviously, if we are resetting the whole GPU, we don't have to worry
      about all of this.

      drm/i915/icl: Record the valid VDBoxes with SFC capability · 57b19d55
      Oscar Mateo authored
      In Gen11, only even numbered "logical" VDBoxes are hooked up to an SFC
      (Scaler & Format Converter) unit. We will use this information to decide
      when the SFC units need to be reset.

      drm/i915/selftests: Verify we can perform resets from atomic context · 921f3a60
      Chris Wilson authored
      We currently require that our per-engine reset can be called from any
      context, even hardirq, and in the future wish to perform the device
      reset without holding struct_mutex (which requires some lockless
      shenanigans that demand the lowlevel intel_reset_gpu() be able to be
      used in atomic context). Test that we meet the current requirements by
      calling i915_reset_engine() from under various atomic contexts.

      After declaring a terminally wedged device, we allow ourselves to
      recover on the next GPU reset (manually triggered), or resume. Check
      that resetting a wedged device does work.

      wakeref) and early warning to i915_reset() for missed wakerefs

      drm/i915: merge gen checks to use range · f3ce44a0
      Lucas De Marchi authored
      Instead of using IS_GEN() for consecutive gen checks, let's pass the
      range to IS_GEN_RANGE(). By code inspection these were the ranges deemed
      necessary for spatch:
      
      @@
      expression e;
      @@
      (
      - IS_GEN(e, 3) || IS_GEN(e, 2)
      + IS_GEN_RANGE(e, 2, 3)
      |
      - IS_GEN(e, 3) || IS_GEN(e, 4)
      + IS_GEN_RANGE(e, 3, 4)
      |
      - IS_GEN(e, 5) || IS_GEN(e, 6)

      - IS_GEN(e, 6) || IS_GEN(e, 7)

      )
      
      After conversion, checking we don't have any missing IS_GEN_RANGE() ||
      IS_GEN() was also done.
