+    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.
+

+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 memOffset,
+                                       boolean commit);
+
+        void NamedBufferPageCommitmentMemNV(uint buffer,
+                                            intptr offset,
+                                            sizeiptr size,
+                                            uint memory, uint64 memOffset,
+                                            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 <memOffset>.
+
+    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,

+    behaves similarly to TexPageCommitmentMemARB and

+
+    <layer> indicates the layer of a texture array or cube texture,

+    <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.

+    OpenGL ES Extension #330
+
+Dependencies
+
+    Written against the OpenGL 4.6 and OpenGL ES 3.2 specifications.
+
+    GL_NV_timeline_semaphore requires GL_EXT_semaphore or a version of
+    OpenGL or OpenGL ES that incorporates it.
+
+Overview
+
+    The Vulkan API introduces the concept of timeline semaphores.
+    This extension brings those concepts to the OpenGL API by adding
+    a semaphore type to the semaphore object. In OpenGL, timeline semaphore
+    signal and wait operations are similar to the corresponding operations on
+    imported Direct3D 12 fences defined in EXT_external_objects_win32.
+
+New Procedures and Functions
+
+    void CreateSemaphoresNV(sizei n, uint *semaphores);
+
+    void SemaphoreParameterivNV(uint semaphore,
+                                enum pname,
+                                const GLint *params);
+
+    void GetSemaphoreParameterivNV(uint semaphore,
+                                   enum pname,
+                                   int *params);
+
+New Tokens
+
+    Accepted by the <pname> parameter of SemaphoreParameterivNV
+    and GetSemaphoreParameterivNV:
+
+        SEMAPHORE_TYPE_NV                           0x95B3
+
+    Accepted by the <param> parameter of SemaphoreParameterivNV and
+    GetSemaphoreParameterivNV when <pname> parameter is SEMAPHORE_TYPE_NV:
+
+        SEMAPHORE_TYPE_BINARY_NV                    0x95B4
+        SEMAPHORE_TYPE_TIMELINE_NV                  0x95B5
+
+    Accepted by the <pname> parameter of SemaphoreParameterui64vNV
+    and GetSemaphoreParameterui64vNV:
+
+        TIMELINE_SEMAPHORE_VALUE_NV                 0x9595
+
+    Accepted by the <pname> parameter to GetIntegerv, GetFloatv, GetDoublev,
+    GetInteger64v, and GetBooleanv:
+
+        MAX_TIMELINE_SEMAPHORE_VALUE_DIFFERENCE_NV  0x95B6
+
+
+Additions to Chapter 4 of the OpenGL 4.6 Specification (Event Model)
+
+    Add the following to section 4.2 Semaphore Objects after paragraph
+    which describes command GenSemaphoresEXT:
+
+        The command
+
+            void CreateSemaphoresNV(sizei n,
+                                    uint *semaphores);
+
+        returns <n> previously unused semaphore names in <semaphores>.
+        The semaphores named contain default state, but initially have no
+        external semaphores associated with them.
+
+    Replace section 4.2.2 Semaphore Parameters with the following:
+
+        Semaphore parameters control the type of the semaphore and how
+        semaphore wait and signal operations behave.
+        Table 4.3 defines which parameters are available for a semaphore
+        based on the external handle type from which it was imported.
+        Semaphore parameters are set using the commands
+
+            void SemaphoreParameterivNV(uint semaphore,
+                                        enum pname,
+                                        const int *params);
+
+        and
+
+            void SemaphoreParameterui64vEXT(uint semaphore,
+                                            enum pname,
+                                            const uint64 *params);
+
+        <semaphore> is the name of the semaphore object on which the
+        parameter <pname> will be set to the value(s) in <pname>.
+
+        Table 4.3: Semaphore parameters
+
+        | Name                        | Handle Types                | Legal Values                         |
+        +-----------------------------+-----------------------------+--------------------------------------+
+        | SEMAPHORE_TYPE_NV           | any handle type             | SEMAPHORE_TYPE_BINARY_NV (default)   |
+        |                             |                             | SEMAPHORE_TYPE_TIMELINE_NV           |
+        +-----------------------------+-----------------------------+--------------------------------------+
+        | TIMELINE_SEMAPHORE_VALUE_NV | any handle type             | any value                            |
+        +-----------------------------+-----------------------------+--------------------------------------+
+
+        The default type of a semaphore is SEMAPHORE_TYPE_BINARY_NV. Only when the semaphore is imported
+        from a D3D fence, the semaphore type defaults to SEMAPHORE_TYPE_TIMELINE_NV.
+
+        Parameters of a semaphore object may be queried with the commands
+
+            void GetSemaphoreParameteriEXT(uint semaphore,
+                                           enum pname,
+                                           uint64 *params);
+
+        and
+
+            void GetSemaphoreParameterui64EXT(uint semaphore,
+                                              enum pname,
+                                              uint64 *params);
+
+        <semaphore> is the semaphore object from with the parameter <pname>
+        is queried.  The value(s) of the parameter are returned in <params>.
+        <pname> may be any value in table 4.3.
+
+    Add the following after the first paragraph of section 4.2.3 "Waiting
+    for Semaphores"
+
+        If <semaphore> is of the type SEMAPHORE_TYPE_TIMELINE_NV, it will
+        reach the signaled state when its value is greater than or equal
+        to the value specified by its TIMELINE_SEMAPHORE_VALUE_NV parameter.
+
+    Add the following at the end of section 4.2.3 "Waiting for Semaphores":
+
+        When using binary semaphores, for every wait on a semaphore there must
+        be a prior signal of that semaphore that will not be consumed by a
+        different wait on the semaphore.
+        When using timeline semaphores, wait-before-signal behavior is
+        well-defined and applications can wait for semaphore before the
+        corresponding semaphore signal operation is flushed.
+
+        MAX_TIMELINE_SEMAPHORE_VALUE_DIFFERENCE_NV indicates the maximum
+        difference allowed by the implementation between the current value
+        of a timeline semaphore and any pending wait operations
+
+    Add the following after the first paragraph of section 4.2.4 "Signaling
+    Semaphores"
+
+        If <semaphore> is of the type SEMAPHORE_TYPE_TIMELINE_NV, its value
+        will be set to the value specified by its TIMELINE_SEMAPHORE_VALUE_NV
+        parameter when the signal operation completes.
+
+    Add the following at the end of section 4.2.4 "Signaling for Semaphores":
+
+        MAX_TIMELINE_SEMAPHORE_VALUE_DIFFERENCE_NV indicates the maximum
+        difference allowed by the implementation between the current value
+        of a timeline semaphore and any pending signal operations.
+
+
+Example
+
+    GLuint semapohre;
+    glCreateSemaphoresNV(1, &semaphore);
+    GLenum semaphoreType = GL_SEMAPHORE_TYPE_TIMELINE_NV;
+    glSemaphoreParameterivNV(semaphore, GL_SEMAPHORE_TYPE_NV, (GLint*)&semaphoreType);
+    glImportSemaphoreFdEXT(semaphore, GL_HANDLE_TYPE_OPAQUE_FD_EXT, fd); // or win32 equivalent
+
+    GLuint64 semaphoreValue = 0;
+
+    while (...) {
+        glSemaphoreParameterui64vEXT(semaphore, GL_TIMELINE_SEMAPHORE_VALUE_NV, &semaphoreValue);
+        glWaitSemaphoreEXT(semaphore, ...);
+
+        ...
+
+        semaphoreValue ++;
+        glSemaphoreParameterui64vEXT(semaphore, GL_TIMELINE_SEMAPHORE_VALUE_NV, &semaphoreValue);
+        glSignalSemaphoreEXT(semaphore, ...);
+    }
+
+    glDeleteSemaphoresEXT(1, &semaphore);
+
+
+Issues
+
+    (1) Should we add client functions to signal and wait for the semaphore on
+        the CPU?
+
+        RESOLVED: No. We already declined to add external Vulkan fence interop
+                  with GL on the basis that you can just do that with Vulkan
+                  if you need it.
+
+    (2) Should GetIntegerv and GetBooleanv be allowed to query
+        MAX_TIMELINE_SEMAPHORE_VALUE_DIFFERENCE_NV?
+
+        RESOLVED: Yes. Although it's dangerous to use them they don't throw an
+                  error but you are advised to use GetInteger64v.
