@@ -632,6 +632,10 @@ The integer capabilities:
 * ``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.
 * ``PIPE_CAP_DRAW_VERTEX_STATE``: Driver supports `pipe_screen::create_vertex_state/vertex_state_destroy` and `pipe_context::draw_vertex_state`. Only used by display lists and designed to serve vbo_save.
 * ``PIPE_CAP_PREFER_POT_ALIGNED_VARYINGS``: Driver prefers varyings to be aligned to power of two in a slot. If this cap is enabled, vec4 varying will be placed in .xyzw components of the varying slot, vec3 in .xyz and vec2 in .xy or .zw
+* ``PIPE_CAP_MAX_SPARSE_TEXTURE_SIZE``: Maximum 1D/2D/rectangle texture image dimension for a sparse texture.
+* ``PIPE_CAP_MAX_SPARSE_3D_TEXTURE_SIZE``: Maximum 3D texture image dimension for a sparse texture.
+* ``PIPE_CAP_MAX_SPARSE_ARRAY_TEXTURE_LAYERS``: Maximum number of layers in a sparse array texture.
+* ``PIPE_CAP_SPARSE_TEXTURE_FULL_ARRAY_CUBE_MIPMAPS``: TRUE if there are no restrictions on the allocation of mipmaps in sparse textures and FALSE otherwise. See SPARSE_TEXTURE_FULL_ARRAY_CUBE_MIPMAPS_ARB description in ARB_sparse_texture extension spec.
