| * For color images that have an auxiliary surface, request allocation for an |
| * additional buffer that mainly stores fast-clear values. Use of this buffer |
| * allows us to access the image's subresources while being aware of their |
| * fast-clear values in non-trivial cases (e.g., outside of a render pass in |
| * which a fast clear has occurred). |
| * |
| * For the purpose of discoverability, the algorithm used to manage this buffer |
| * is described here. A clear value in this buffer is updated when a fast clear |
| * is performed on a subresource. One of two synchronization operations is |
| * performed in order for a following memory access to use the fast-clear |
| * value: |
| * a. Copy the value from the buffer to the surface state object used for |
| * reading. This is done implicitly when the value is the clear value |
| * predetermined to be the default in other surface state objects. This |
| * is currently only done explicitly for the operation below. |
| * b. Do (a) and use the surface state object to resolve the subresource. |
| * This is only done during layout transitions for decent performance. |
| * |
| * With the above scheme, we can fast-clear whenever the hardware allows except |
| * for two cases in which synchronization becomes impossible or undesirable: |
| * * The subresource is in the GENERAL layout and is cleared to a value |
| * other than the special default value. |
| * |
| * Performing a synchronization operation in order to read from the |
| * subresource is undesirable in this case. Firstly, b) is not an option |
| * because a layout transition isn't required between a write and read of |
| * an image in the GENERAL layout. Secondly, it's undesirable to do a) |
| * explicitly because it would require large infrastructural changes. The |
| * Vulkan API supports us in deciding not to optimize this layout by |
| * stating that using this layout may cause suboptimal performance. NOTE: |
| * the auxiliary buffer must always be enabled to support a) implicitly. |
| * |
| * |
| * * For the given miplevel, only some of the layers are cleared at once. |
| * |
| * If the user clears each layer to a different value, then tries to |
| * render to multiple layers at once, we have no ability to perform a |
| * synchronization operation in between. a) is not helpful because the |
| * object can only hold one clear value. b) is not an option because a |
| * layout transition isn't required in this case. |
