This little series adds a PBO texture upload path based on meta. We do so by adding a little driver hook for creating a 2D or 2D array texture from a gl_buffer_object and then using this together with BlitFramebuffers to do the upload. Since Intel hardware can take basically any buffer and treat it as a linear texture, this works fairly well.
This series requires the texture upload modifications posted by Samuel and Iago Git branch for review or merging: http://cgit.freedesktop.org/~jekstrand/mesa/log/?h=review/meta-pbo-upload Jason Ekstrand (5): i965/mipmap_tree: Add a depth parameter to create_for_bo mesa/dd: Add a function for creating a texture from a buffer object i965: Implement SetTextureStorageForBufferObject meta: Add a BlitFramebuffers-based implementation of TexSubImage i965: Use _mesa_meta_TexSubImage for PBO's and cases where the texture is busy src/mesa/Makefile.sources | 1 + src/mesa/drivers/common/meta.h | 9 ++ src/mesa/drivers/common/meta_tex_subimage.c | 211 +++++++++++++++++++++++++ src/mesa/drivers/dri/i965/intel_fbo.c | 1 + src/mesa/drivers/dri/i965/intel_mipmap_tree.c | 9 +- src/mesa/drivers/dri/i965/intel_mipmap_tree.h | 1 + src/mesa/drivers/dri/i965/intel_pixel_draw.c | 2 +- src/mesa/drivers/dri/i965/intel_pixel_read.c | 2 +- src/mesa/drivers/dri/i965/intel_tex.c | 44 ++++++ src/mesa/drivers/dri/i965/intel_tex_image.c | 18 ++- src/mesa/drivers/dri/i965/intel_tex_subimage.c | 10 ++ src/mesa/main/dd.h | 14 ++ 12 files changed, 313 insertions(+), 9 deletions(-) create mode 100644 src/mesa/drivers/common/meta_tex_subimage.c -- 2.2.0 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
