  10 #     win, xp, vista, win7, mac, leopard, snowleopard, lion, mountainlion,
  11 #     mavericks, yosemite, linux, chromeos, android
  12 #
  13 # GPU vendors:
  14 #     amd, arm, broadcom, hisilicon, intel, imagination, nvidia, qualcomm,
  15 #     vivante
  16 #
  17 # Direct3D status:
  18 #     d3d9, d3d11

  21 # Examples: ('nvidia', 0x1234), ('arm', 'Mali-T604')
  22 # Device IDs must be paired with a GPU vendor.

  25 #   self.Fail('gl-enable-vertex-attrib.html',
  26 #       ['mac', 'amd', ('nvidia', 0x1234)], bug=123)
