Amirali Abdolrashidi 89e11878 2021-12-06T09:42:46 Vulkan: Fix the UAF issue with BufferData * Fixed the use-after-free issue with stale buffer handles after calling BeginTransformFeedback. * Added an observer for TransformFeedbackVk to update the buffer handles when buffer's storage is changed and the buffer update type is StorageRedefined. * Added a function to TransformFeedbackVk::onDestroy() to release the counter buffers in order to avoid crash due to TransformFeedbackVk::end() not being called, e.g., as a result of no glEndTransformFeedback() calls.

Tim Van Patten 68c0da83 2021-09-15T12:00:08 Vulkan: Inform frontend when new buffer is allocated When a buffer is mapped with GL_MAP_INVALIDATE_BUFFER_BIT while it's currently in use, the Vulkan backend will allocate a new buffer, map it, and return the pointer to the new buffer. This was missing a call to inform the frontend that a new buffer was allocated, causing the old buffer data to be accessed in subsequent draw calls. The fix is to add a onStateChange(angle::SubjectMessage::SubjectGhosted) call when the new buffer is allocated, to inform the frontend.

Tim Van Patten 220642a9 2020-12-16T21:10:37 Allow Drawing with Immutable Persistent Mapped Buffers From the EXT_buffer_storage overview: The GL_EXT_texture_storage extension added immutable storage for texture objects (and was subsequently incorporated into OpenGL ES 3.0). This extension further applies the concept of immutable storage to buffer objects. [T]his extension introduces the concept of persistent client mappings of buffer objects, which allow clients to retain pointers to a buffer's data store returned as the result of a mapping, and to issue drawing commands while those mappings are in place. The initial implementation of EXT_buffer_storage didn't enable this portion of the extension, so ANGLE is generating errors while attempting to draw with an immutable buffer mapped with the GL_MAP_PERSISTENT_BIT flag. This CL enables that functionality, since apps (e.g., FIFA Soccer) rely on it.

Note that Vulkan doesn't support NULL buffer bindings. Thus we create an emulated NULL buffer to work around the problem of having gaps in the bound vertex buffers. This allows us to use a single bind call for ranges of vertex buffers even when there are gaps. Also changes how vertex array dirty bits are reset. Instead of calling memset to clear the affected buffers we pass a mutable pointer to the Vertex Array sync state. This allows us to only reset the dirty bits that we sync.

The next level has separate dirty bits for attribs and bindings.

Improves the score of a simple state change microbenchmark by 15% on the D3D11 and GL back-ends with a no-op driver. Real-world impact will be smaller.

Jiawei-Shao 2597fb64 2016-12-09T16:38:02 ES31: Refactor VertexArray for Vertex Attrib Binding OpenGL ES3.1 feature Vertex Attrib Binding requires vertex arrays should be split into two arrays: 1. an array of vertex buffer binding points, each of which specifies: - a bound buffer object, - a starting offset for vertex attribute data in that buffer object, - a stride used by all attributes using that binding point, - a frequency divisor used by all attributes using that binding point. 2. an array of generic vertex attribute format information records, each of which specifies: - a reference to one of the new buffer binding points above, - a component count and format, and a normalization flag for the attribute data, - the offset of the attribute data relative to the base offset of each vertex found at the associated binding point. Current ANGLE implementation simply uses a struct to represent a vertex attribute object, which does not meet the requirements above. This patch aims to be the the basis of the implementation of all ES3.1 Vertex Attrib Binding APIs by refactoring the struct VertexAttribute and the class VertexArray to fit the new data layout and ensuring all current functionality is retained.

Currently dynamic attributes must be re-translated every call, so these are stored in a list and processed repeatedly.

Current value attributes, which correspond to disabled attributes that the program will pulls vertex data from, are owned by the Context, so these need to be handled outside of the VertexArray11. Further changes will be necessary to reduce the redundant work we do in the InputLayoutCache. We shouldn't need to re-check the cache if nothing relevant changed.
