* ``PIPE_CAP_EMULATE_NONFIXED_PRIMITIVE_RESTART``: Driver requests all draws using a non-fixed restart index to be rewritten to use a fixed restart index.
* ``PIPE_CAP_SUPPORTED_PRIM_MODES``: A bitmask of the ``pipe_prim_type`` enum values that the driver can natively support.
* ``PIPE_CAP_SUPPORTED_PRIM_MODES_WITH_RESTART``: A bitmask of the ``pipe_prim_type`` enum values that the driver can natively support for primitive restart. Only useful if ``PIPE_CAP_PRIMITIVE_RESTART`` is also exported.
* ``PIPE_CAP_PREFER_BACK_BUFFER_REUSE``: Only applies to DRI_PRIME. If 1, the driver prefers that DRI3 tries to use the same back buffer each frame. If 0, this means DRI3 will at least use 2 back buffers and ping-pong between them to allow the tiled->linear copy to run in parallel.
