      broadcom/vc5: Update the UABI for in/out syncobjs · b225cdce
      Eric Anholt authored
      This is the ABI I'm hoping to stabilize for merging the driver.  seqnos
      are eliminated, which allows for the GPU scheduler to task-switch between
      DRM fds even after submission to the kernel.  In/out sync objects are
      introduced, to allow the Android fencing extension (not yet implemented,
      but should be trivial), and to also allow the driver to tell the kernel to
      not start a bin until a previous render is complete.

      broadcom: Add V3D 3.3 gallium driver called "vc5", for BCM7268. · 45bb8f29
      Eric Anholt authored
      V3D 3.3 is a continuation of the 3D implementation in VC4 (v2.1 and v2.6).
      V3D 3.3 introduces an MMU (no more CMA allocations) and support for
      GLES3.1.  This driver is not currently conformant, though that will be a
      target as soon as possible.
      V3D 3.x parts use a new texture tiling layout common across many Broadcom
      graphics parts including and the HVS scanout engine.  It also massively
      changes the QPU instructions, introducing a common physical register file
      (no more A/B split) and half-float instructions, while removing the 4x8
      unorm instructions in favor of half-float for talking to fixed function
      interfaces.  Because so much has changed, vc5 is implemented in a separate
      gallium driver, using only the XML code-generation support from vc4.
      v2: Fix tile layout for 64bpp textures.  Fix texture swizzling for 32-bit
          returns.  Fix up a bit of MRT setup.  Sync the simulator to kernel
          behavior a bit more.  Improve uniform debugging code.  Rebase on
          QIR->VIR rename.  Move texture state mostly to the CSOs.  Improve
          cache flushing on the simulator.  Fix program deletion
