gallium/st: add pipe_context::generate_mipmap()
This patch adds a new interface to support hardware mipmap generation. PIPE_CAP_GENERATE_MIPMAP is added to allow a driver to specify if this new interface is supported; if not supported, the state tracker will fallback to mipmap generation by rendering/texturing. v2: add PIPE_CAP_GENERATE_MIPMAP to the disabled section for all drivers v3: add format to the generate_mipmap interface to allow mipmap generation using a format other than the resource format v4: fix return type of trace_context_generate_mipmap() Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>
