148 * below. The lower 56 bits are assigned as vendor sees fit.

174 * Intel X-tiling layout
176 * This is a tiled layout using 4Kb tiles (except on gen2 where the tiles 2Kb)
177 * in row-major layout. Within the tile bytes are laid out row-major, with
178 * a platform-dependent stride. On top of that the memory can apply
179 * platform-depending swizzling of some higher address bits into bit6.
181 * This format is highly platforms specific and not useful for cross-driver
182 * sharing. It exists since on a given platform it does uniquely identify the
183 * layout in a simple way for i915-specific userspace.
185 #define I915_FORMAT_MOD_X_TILED fourcc_mod_code(INTEL, 1)
188 * Intel Y-tiling layout
190 * This is a tiled layout using 4Kb tiles (except on gen2 where the tiles 2Kb)
191 * in row-major layout. Within the tile bytes are laid out in OWORD (16 bytes)
192 * chunks column-major, with a platform-dependent height. On top of that the
193 * memory can apply platform-depending swizzling of some higher address bits
194 * into bit6.
196 * This format is highly platforms specific and not useful for cross-driver
197 * sharing. It exists since on a given platform it does uniquely identify the
198 * layout in a simple way for i915-specific userspace.
200 #define I915_FORMAT_MOD_Y_TILED fourcc_mod_code(INTEL, 2)
203 * Intel Yf-tiling layout
205 * This is a tiled layout using 4Kb tiles in row-major layout.
206 * Within the tile pixels are laid out in 16 256 byte units / sub-tiles which
207 * are arranged in four groups (two wide, two high) with column-major layout.
208 * Each group therefore consits out of four 256 byte units, which are also laid
209 * out as 2x2 column-major.
210 * 256 byte units are made out of four 64 byte blocks of pixels, producing
211 * either a square block or a 2:1 unit.
212 * 64 byte blocks of pixels contain four pixel rows of 16 bytes, where the width
213 * in pixel depends on the pixel depth.
215 #define I915_FORMAT_MOD_Yf_TILED fourcc_mod_code(INTEL, 3)
218 * Tiled, NV12MT, grouped in 64 (pixels) x 32 (lines) -sized macroblocks
220 * Macroblocks are laid in a Z-shape, and each pixel data is following the
221 * standard NV12 style.
222 * As for NV12, an image is the result of two frame buffers: one for Y,
223 * one for the interleaved Cb/Cr components (1/2 the height of the Y buffer).
224 * Alignment requirements are (for each buffer):
225 * - multiple of 128 pixels for the width
226 * - multiple of 32 pixels for the height
228 * For more information: see https://linuxtv.org/downloads/v4l-dvb-apis/re32.html
