      drm/etnaviv: initialize iommu domain page size · 13c34fe5
      Lucas Stach authored
      Since d16e0faa (iommu: Allow selecting page sizes per domain) the
      iommu core demands the page size to be set per domain, otherwise any
      mapping attempts will be dropped. Make sure to set a valid page size
      for the etnaviv iommu.

      drm/nouveau/Revert "drm/nouveau/device/pci: set as non-CPU-coherent on ARM64" · 539aae6e
      Robin Murphy authored
      This reverts commit 1733a2ad.
      
      There is apparently something amiss with the way the TTM code handles
      DMA buffers, which the above commit was attempting to work around for
      arm64 systems with non-coherent PCI. Unfortunately, this completely
      breaks systems *with* coherent PCI (which appear to be the majority).
      
      Booting a plain arm64 defconfig + CONFIG_DRM + CONFIG_DRM_NOUVEAU on
      a machine with a PCI GPU having coherent dma_map_ops (in this case a
      7600GT card plugged into an ARM Juno board) results in a fatal crash:

      In a toss-up between the GPU seeing stale data artefacts on some systems
      vs. catastrophic kernel crashes on other systems, the latter would seem
      to take precedence, so revert this change until the real underlying
      problem can be fixed.

      drm/crtc: fix connector reference counting mismatch in drm_crtc_helper_set_config · fffc5f59
      Philipp Zabel authored
      Since commit 0955c125 ("drm/crtc: take references to connectors used
      in a modeset. (v2)"), the reference counts of all connectors in the
      drm_mode_set given to drm_crtc_helper_set_config are incremented, and then
      the reference counts of all connectors are decremented on success, but in a
      temporary copy of the connector structure. This leads to the following
      error after the first modeset on imx-drm:

      Only the reference count of connectors that weren't previously bound to
      an encoder should be incremented after a call to drm_crtc_helper_set_config.
      And only the reference count of connectors that were previously bound to
      an encoder and are unbound afterwards should ever be decremented.
      The reference counts of the temporary copies in the save_connectors
      should not be touched at all.
      
      This patch fixes the above error by only incrementing the reference count
      of those connectors in the set that are initially not bound to any encoder,
      and also by restoring the reference count of only those connectors in the
      set in the failure case.
      
      "Note that this can only be hit when fbdev emulation is disabled, since
      then the refcount drops from 1 to 0 and we call the connector destroy
      functions on the backup copy, which eventually results in tears. With
      fbdev emulation the refcount only goes down from 2 to 1 ever. And since we
      unconditionally increment the refcount on the real object, the refcount of
      that will slowly increase. The backup connector's refcount doesn't matter,
      since we kfree() that either way in the end of
      drm_crtc_helper_set_config()."

      drm/i915/ilk: Don't disable SSC source if it's in use · 476490a9
      Lyude authored
      Thanks to Ville Syrjälä for pointing me towards the cause of this issue.
      
      Unfortunately one of the sideaffects of having the refclk for a DPLL set
      to SSC is that as long as it's set to SSC, the GPU will prevent us from
      powering down any of the pipes or transcoders using it. A couple of
      BIOSes enable SSC in both PCH_DREF_CONTROL and in the DPLL
      configurations. This causes issues on the first modeset, since we don't
      expect SSC to be left on and as a result, can't successfully power down
      the pipes or the transcoders using it. Here's an example from this Dell
      OptiPlex 990:

      Later modesets succeed since they reset the DPLL's configuration anyway,
      but this is enough to get stuck with a big fat warning in dmesg.
      
      A better solution would be to add refcounts for the SSC source, but for
      now leaving the source clock on should suffice.
      
      Changes since v4:
       - Fix calculation of final for systems with LVDS panels (fixes BUG() on
         CI test suite)
      Changes since v3:
       - Move temp variable into loop
       - Move checks for using_ssc_source to after we've figured out has_ck505
       - Add using_ssc_source to debug output
      Changes since v2:
       - Fix debug output for when we disable the CPU source
      Changes since v1:
       - Leave the SSC source clock on instead of just shutting it off on all
         of the DPLL configurations.
