   5 # GLPipeChecksum----------------------------------------------------------------
   6 # For every GL call that transfers between host and guest, GLPipeChecksum = on
   7 # will compute a checksum consisting of some function of the actual bit vector
   8 # corresponding to the GL command, verifying that the same checksum shows up
   9 # on both the host and guest. Violations of the checksum (mismatches) result
  10 # in an abort() and crash report being sent.
  11 #
  12 # Currently, the checksum is mainly making sure that the command itself and all
  13 # arrays passed through the pipe are of proper length.
  14 GLPipeChecksum = on

  17 # GrallocSync-------------------------------------------------------------------
  18 # Most apps that display images do so through OpenGL, but there are some apps
  19 # that write directly to gralloc color buffers. In our goldfish-driver gralloc
  20 # implementation, which represents gralloc color buffers as host OpenGL color
  21 # buffers.
  22 #
  23 # For example, in the camera app, the emulated webcam driver will pull frames
  24 # to a gralloc color buffer directly, and then in another thread or process,
  25 # the color buffer representing the camera frame preview could be posted
  26 # onscreen.
  27 #
  28 # These operations aren't guaranteed to have their order preserved when arriving
  29 # from the guest, and if executed on the host in the wrong order, we could
  30 # end up with out of order webcam frames, for instance.
  31 #
  32 # GrallocSync = on adds synchronization to the host for this use case where apps
  33 # directly write to gralloc color buffers and then post them.
  34 GrallocSync = on
