This includes averge, saturating additiong, saturating subtraction, absolute difference, count leading zeros, and count trailing zeros. * ``PIPE_CAP_INTEGER_MULTIPLY_32X16``: Driver supports integer multiplication between a 32-bit integer and a 16-bit integer. If the second operand is 32-bits, the upper 16-bits are ignored, and the low 16-bits are possibly sign extended as necessary. * ``PIPE_CAP_NIR_IMAGES_AS_DEREF``: Whether NIR image load/store intrinsics should be nir_intrinsic_image_deref_* instead of nir_intrinsic_image_*. Defaults to true. +* ``PIPE_CAP_PACKED_STREAM_OUTPUT``: Driver supports packing optimization for stream output (e.g. GL transform feedback captured variables). Defaults to true. +* ``PIPE_CAP_VIEWPORT_TRANSFORM_LOWERED``: Driver needs the nir_lower_viewport_transform pass to be enabled. This also means that the gl_Position value is modified and should be lowered for transform feedback, if needed. Defaults to false. +* ``PIPE_CAP_PSIZ_CLAMPED``: Driver needs for the point size to be clamped. Additionally, the gl_PointSize has been modified and its value should be lowered for transform feedback, if needed. Defaults to false. .. _pipe_capf: |
