    - 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
    - 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

  • 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
    GPU Fixes:
    - a5xx: fix quirks to actually be a bitmask and not overwrite each
    - a6xx: fix gx halt sequence to avoid 1000ms hang on some devices
    - kexec shutdown fix
    - fix potential double free

  • 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
    - Fix to populate intf_cfg correctly before calling reset_intf_cfg().
      Without this, the display pipeline is not torn down correctly for
    - 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

      probe/bind error paths
