  • drm-msm-fixes-2023-03-09
    msm-fixes for v6.3-rc2
    
    - Fix for possible invalid ptr free in submit ioctl syncobj cleanup path.
    - Synchronize GMU removal in driver teardown path
    - a5xx preemption fixes
    - Fix runpm imbalance at unbind
    - DPU hw catalog fixes:
     - set DPU_MDP_PERIPH_0_REMOVED for sc8280xp as this is another chipset
       where the PERIPH_0 block of registers is not there
     - fix the DPU features supported in QCM2290 by comparing it with the
       downstream device tree
     - fix the length of registers in the sc7180_ctl from 0xe4 to 0x1dc
     - fix the max mixer line width for sm6115 and qcm2290 chipsets in the
       DPU catalog
     - fix the scaler version on sm8550, sc8280xp, sm8450, sm8250, sm8350
       and sm6115. This was incorrectly populated on the SW version of the
       scaler library and  not the scaler HW version
     - Drop dim layer support for msm8998 as its not indicated to be
       supported in the downstream DTSI
     - fix the DPU_CLK_CTRL bits for msm 8998 sspp blocks
     - Use DPU_CLK_CTRL_DMA* prefix instead of DPU_CLK_CTRL_CURSOR*
       for all chipsets for the DMA sspp blocks
     - fix the ping-pong block base address for sc7280 in the DPU HW catalog
    - Fix stack corruption issue in the dpu_hw_ctl_setup_blendstage() function
      as it was causing a negative left shift by protecting against an invalid
      index
    - Clear the DSPP reservations in dpu_rm_release(). This was missed out and
      as as result the DSPP was not released from the resource manager global
      state.
  • drm-msm-next-2023-01-30
    msm-next for v6.3
    
    There is one devfreq patch, maintainer acked to land via msm-next to

    - a2xx: Support to load legacy firmware
    - a6xx: GPU devcore dump updates for a650/a660
    - GPU devfreq tuning and fixes
    
    DPU, DSI, MDSS:
    - Support for SM8350, SM8450 SM8550 and SC8280XP platform
    
    Core:
    - Added bindings for SM8150 (driver support already present)
    
    DPU:
    - Partial support for DSC on SM8150 and SM8250
    - Fixed color transformation matrix being lost on suspend/resume
    - Include DSC blocks into register snapshot
    - Misc HW catalog fixes

    - Support for DP on SDM845 and SC8280XP platforms
    - HPD fixes
    - Support for limiting DP link rate via DT property, this enables
    - Support for HBR3 rates.
    
    DSI:

  • drm-msm-fixes-2023-01-16
    msm-fixes for v6.3-rc5
    
    Two GPU fixes which were meant to be part of the previous pull request,
    but I'd forgotten to fetch from gitlab after the MR was merged so that
    git tag was applied to the wrong commit.
    
    - kexec shutdown fix
    - fix potential double free
  • drm-msm-fixes-2023-01-12
    msm-fixes for v6.3-rc4
    
    Display Fixes:
    
    - Fix the documentation for dpu_encoder_phys_wb_init() and
      dpu_encoder_phys_wb_setup_fb() APIs to address doc warnings
    - Remove vcca-supply and vdds-supply as mandatory for 14nm PHY and
      10nm PHY DT schemas respectively as they are not present on some
      SOCs using these PHYs
    - Add the dsi-phy-regulator-ldo-mode to dsi-phy-28nm.yaml as it was
      missed out during txt to yaml migration
    - Remove operating-points-v2 and power-domain as a required property
      for the DSI controller as thats not the case for every SOC
    - Fix the description from display escape clock to display core
      clock in the dsi controller yaml
    - Fix the memory leak for mdp1-mem path for the cases when we return
      early after failing to get mdp0-mem ICC paths for msm
    - Fix error handling path in msm_hdmi_dev_probe() to release the phy
      ref count when devm_pm_runtime_enable() fails
    - Fix the dp_aux_isr() routine to make sure it doesnt incorrectly
      signal the aux transaction as complete if the ISR was not an AUX
      isr. This fixes a big hitter stability bug on chromebooks.
    - Add protection against null pointer dereference when there is no
      kms object as in the case of headless adreno GPU in the shutdown
      path.
    
    GPU Fixes:
    
    - a5xx: fix quirks to actually be a bitmask and not overwrite each
      other
    - a6xx: fix gx halt sequence to avoid 1000ms hang on some devices
    - kexec shutdown fix
    - fix potential double free

    msm-next for v6.1
    
    DPU:
    - simplified VBIF configuration
    - cleaned up CTL interfaces to accept indices rather than flush masks
    
    DSI:
    - removed unused msm_display_dsc_config struct
    - switch regulator calls to new bulk API

    - support getting interconnects from either the mdss or the mdp5/dpu
      device nodes
    
    gpu+gem:
    - Shrinker + LRU re-work:
      - adds a shared GEM LRU+shrinker helper and moves msm over to that
      - reduces lock contention between retire and submit by avoiding the
        need to acquire obj lock in retire path (and instead using resv
        seeing obj's busyness in the shrinker
      - fix reclaim vs submit issues
    - GEM fault injection for triggering userspace error paths
    - Map/unmap optimization
    - Improved robustness for a6xx GPU recovery
  • drm-msm-fixes-2022-08-27
    Fixes for v6.0
    
    - Fix for inconsistent indenting in function msm_dsi_dphy_timing_calc_v3.
      This fixes a smatch warning reported by kbot
    - Fix to make eDP the first connector in the connected list. This was
      mainly done to address a screen corruption issue we were seeing on
      sc7280 boards which have eDP as the primary display. The corruption
      itself is from usermode but we decided to fix it this way because
      things work correct with the primary display as the first one for
      usermode
    - Fix to populate intf_cfg correctly before calling reset_intf_cfg().
      Without this, the display pipeline is not torn down correctly for
      writeback
    - Specify the correct number of DSI regulators for SDM660. It should
      have been 1 but 2 was mentioned
    - Specify the correct number of DSI regulators for MSM8996. It should
      have been 3 but 2 was mentioned
    - Fix for removing DP_RECOVERED_CLOCK_OUT_EN bit for tps4 link training
      for DP. This was causing link training failures and hence no display
      for a specific DP to HDMI cable on chromebooks
    - Fix probe-deferral crash in gpu devfreq
    - Fix gpu debugfs deadlock

  • drm-msm-fixes-2022-06-28
    Fixes for v5.19-rc5
    
    - Fix to increment vsync_cnt before calling drm_crtc_handle_vblank so that
      userspace sees the value *after* it is incremented if waiting for vblank
      events
    - Fix to reset drm_dev to NULL in dp_display_unbind to avoid a crash in
      probe/bind error paths
    - Fix to resolve the smatch error of de-referencing before NULL check in
      dpu_encoder_phys_wb.c
    - Fix error return to userspace if fence-id allocation fails in submit
      ioctl
