132 * \brief A fast path for glTexImage and glTexSubImage.
134 * This fast path is taken when the texture format is BGRA, RGBA,
135 * A or L and when the texture memory is X- or Y-tiled. It uploads
136 * the texture data by mapping the texture memory without a GTT fence, thus
137 * acquiring a tiled view of the memory, and then copying sucessive
138 * spans within each tile.
140 * This is a performance win over the conventional texture upload path because
141 * it avoids the performance penalty of writing through the write-combine
142 * buffer. In the conventional texture upload path,
143 * texstore.c:store_texsubimage(), the texture memory is mapped through a GTT
144 * fence, thus acquiring a linear view of the memory, then each row in the
145 * image is memcpy'd. In this fast path, we replace each row's copy with
146 * a sequence of copies over each linear span in tile.
148 * One use case is Google Chrome's paint rectangles. Chrome (as
149 * of version 21) renders each page as a tiling of 256x256 GL_BGRA textures.
150 * Each page's content is initially uploaded with glTexImage2D and damaged
151 * regions are updated with glTexSubImage2D. On some workloads, the
152 * performance gain of this fastpath on Sandybridge is over 5x.
