+ OpenGL ES Extension #329
+
+Dependencies
+
+ Written against the OpenGL 4.6 and OpenGL ES 3.2 specifications
+ including ARB_sparse_texture and ARB_sparse_buffer.
+
+ GL_NV_memory_object_sparse requires GL_EXT_memory_object,
+ ARB_sparse_texture and/or ARB_sparse_buffer or a version of
+ OpenGL or OpenGL ES that incorporates it.
+
+ NV_memory_object_sparse interacts with ARB_direct_state_access (OpenGL)
+ when OpenGL < 4.6 is used.
+
+ ARB_sparse_texture (OpenGL) interacts with GL_EXT_memory_object_sparse.
+ ARB_sparse_buffer (OpenGL) interacts with GL_EXT_memory_object_sparse.
+ EXT_sparse_texture (OpenGL ES) interacts with GL_EXT_memory_object_sparse.
+
+Overview
+
+ This extension adds sparse support to EXT_memory_object extension.
+
+New Procedures and Functions
+
+ void BufferPageCommitmentMemNV(enum target,
+ intptr offset, sizeiptr size,
+ uint memory, uint64 offset,
+ boolean commit);
+
+ void NamedBufferPageCommitmentMemNV(uint buffer,
+ intptr offset, sizeiptr size,
+ uint memory, uint64 offset,
+ boolean commit);
+
+ void TexPageCommitmentMemNV(enum target,
+ int layer, int level,
+ int xoffset, int yoffset, int zoffset,
+ sizei width, sizei height, sizei depth,
+ uint memory, uint64 offset,
+ boolean commit);
+
+ void TexturePageCommitmentMemNV(uint texture,
+ int layer, int level,
+ int xoffset, int yoffset, int zoffset,
+ sizei width, sizei height, sizei depth,
+ uint memory, uint64 offset,
+ boolean commit);
+
+
+New Tokens
+
+ None
+
+
+Additions to Chapter 6 of the OpenGL 4.4 (core) Specification (Buffer Objects)
+
+ In Section 6.2, "Creating and Modifying Buffer Object Data Stores", add
+ the following add the following to the end of the description of
+ BufferSubData:
+
+ If NV_memory_object_sparse is supported, additionally, the commands
+
+ void BufferPageCommitmentMemNV(enum target,
+ intptr offset, sizeiptr size,
+ uint memory, uint64 offset,
+ boolean commit);
+
+ void NamedBufferPageCommitmentMemNV(uint buffer,
+ intptr offset,
+ sizeiptr size,
+ uint memory, uint64 offset,
+ boolean commit);
+
+ behaves similarly to BufferPageCommitmentARB and
+ NamedBufferPageCommitmentMemARB except that the pages of the sparse buffer
+ are bound to the memory specified by <memory> and <offset>.
+
+ Errors (additionally to non-Mem variants)
+
+ An INVALID_OPERATION error is generated if <memory> is not the name of
+ an existing memory object.
+
+ An INVALID_OPERATION error is generated if <offset> + <size> exceeds the
+ size of the memory object.
+
+ Add the following to end of subsection 8.20.2. "Controlling Sparse Texture
+ Commitment":
+
+ If NV_memory_object_sparse is supported, additionally, the commands
+
+ void TexPageCommitmentMemNV(enum target,
+ int layer, int level,
+ int xoffset, int yoffset, int zoffset,
+ sizei width, sizei height, sizei depth,
+ uint memory, uint64 offset,
+ boolean commit);
+
+ void TexturePageCommitmentMemNV(uint texture,
+ int layer, int level,
+ int xoffset, int yoffset, int zoffset,
+ sizei width, sizei height, sizei depth,
+ uint memory, uint64 offset,
+ boolean commit);
+
+ behaves similarly to TexPageCommitmentMemARB and
+ TexturePageCommitmentEXT except that the tiles of the sparse texture
+ are bound to the memory specified by <memory> and <offset>.
+
+ <layer> indicates the layer of a texture array or cube texture,
+ <zoffset> must be 0 and <depth> must 1 in this case. For other textures
+ <layer> must be 0.
+
+ Errors (additionally to non-Mem variants)
+
+ An INVALID_OPERATION error is generated if <memory> is not the name of
+ an existing memory object.
+
+ An INVALID_OPERATION error is generated if <memory> is dedicated or
+ imported from a non-opaque handle.
+
+ An INVALID_OPERATION error is generated if <offset> plus the number of
+ bytes required for the tiles to commit exceeds the size of the memory
+ object.
+
+ An INVALID_VALUE error is generated if <layer> is not 0 and the texture
+ neither a texture array or a cube texture.
+
+ An INVALID_VALUE error is generated if <zoffset> is not 0 or <depth> is
+ not 1 if the texture is a texture array or a cube texture.
+
+ An INVALID_VALUE error is generated if <layer> is greater or equal than
+ the number of layers of the texture array.
+
+ An INVALID_VALUE error is generated if <layer> is greater or equal than
+ 6 in case of a cube texture.
+
+Dependencies on EXT_direct_state_access
+
+ If EXT_direct_state_access is not supported, remove references to the
+ NamedBufferPageCommitmentMemNV and TexturePageCommitmentMemNV commands
+ added by this extension.
+
+Issues
+
+ (1) Should we a 'aspect' parameter to the new gl.*CommitMemNV() functions?
+
+ RESOLVED: No. This can be deferred to a future EXT extension because there
+ is currently no multi-planar texture support in GL and metadata
+ isn't required for NVIDIA hardware.
