From: Charmaine Lee Date: Thu, 14 Jan 2016 17:22:17 +0000 (-0700) Subject: gallium/st: add pipe_context::generate_mipmap() X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3038e8984df2be35a7164043ec6d385e32e26238;p=mesa.git 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 Reviewed-by: Roland Scheidegger Reviewed-by: Jose Fonseca --- diff --git a/src/gallium/docs/source/context.rst b/src/gallium/docs/source/context.rst index 9a32716f921..4c03e00008c 100644 --- a/src/gallium/docs/source/context.rst +++ b/src/gallium/docs/source/context.rst @@ -648,3 +648,14 @@ In addition, normal texture sampling is allowed from the compute program: ``bind_sampler_states`` may be used to set up texture samplers for the compute stage and ``set_sampler_views`` may be used to bind a number of sampler views to it. + +Mipmap generation +^^^^^^^^^^^^^^^^^ + +If PIPE_CAP_GENERATE_MIPMAP is true, ``generate_mipmap`` can be used +to generate mipmaps for the specified texture resource. +It replaces texel image levels base_level+1 through +last_level for layers range from first_layer through last_layer. +It returns TRUE if mipmap generation succeeds, otherwise it +returns FALSE.
