191 * For color images that have an auxiliary surface, request allocation for an
192 * additional buffer that mainly stores fast-clear values. Use of this buffer
193 * allows us to access the image's subresources while being aware of their
194 * fast-clear values in non-trivial cases (e.g., outside of a render pass in
195 * which a fast clear has occurred).
197 * In order to avoid having multiple clear colors for a single plane of an
198 * image (hence a single RENDER_SURFACE_STATE), we only allow fast-clears on
199 * the first slice (level 0, layer 0). At the time of our testing (Jan 17,
200 * 2018), there were no known applications which would benefit from fast-
201 * clearing more than just the first slice.
203 * The fast clear portion of the image is laid out in the following order:
205 * * 1 or 4 dwords (depending on hardware generation) for the clear color
206 * * 1 dword for the anv_fast_clear_type of the clear color
207 * * On gen9+, 1 dword per level and layer of the image (3D levels count
208 * multiple layers) in level-major order for compression state.
210 * For the purpose of discoverability, the algorithm used to manage
211 * compression and fast-clears is described here:
213 * * On a transition from UNDEFINED or PREINITIALIZED to a defined layout,
214 * all of the values in the fast clear portion of the image are initialized
217 * * On fast-clear, the clear value is written into surface state and also
218 * into the buffer and the fast clear type is set appropriately. Both
219 * setting the fast-clear value in the buffer and setting the fast-clear
220 * type happen from the GPU using MI commands.
222 * * Whenever a render or blorp operation is performed with CCS_E, we call
223 * genX(cmd_buffer_mark_image_written) to set the compression state to
224 * true (which is represented by UINT32_MAX).
226 * * On pipeline barrier transitions, the worst-case transition is computed
227 * from the image layouts. The command streamer inspects the fast clear
228 * type and compression state dwords and constructs a predicate. The
229 * worst-case resolve is performed with the given predicate and the fast
230 * clear and compression state is set accordingly.
232 * See anv_layout_to_aux_usage and anv_layout_to_fast_clear_type functions for
233 * details on exactly what is allowed in what layouts.
235 * On gen7-9, we do not have a concept of indirect clear colors in hardware.
236 * In order to deal with this, we have to do some clear color management.
238 * * For LOAD_OP_LOAD at the top of a renderpass, we have to copy the clear
239 * value from the buffer into the surface state with MI commands.
241 * * For any blorp operations, we pass the address to the clear value into
242 * blorp and it knows to copy the clear color.
