@ -694,3 +694,61 @@ Internal Issues:
* Update the <<sparsememory-sparse-memory-aliasing,Sparse Resource
Implementation Guidelines>> to refer to the correct feature names
(internal issue 305).
-----------------------------------------------------
Change log for June 10, 2016 Vulkan 1.0.16 spec update:
* Bump API patch number and header version number to 16 for this
update.
Github Issues:
* Clarify that integer border values are meant to be 0/1, and that
integer texture lookups are sign-extended in the
<<textures-format-conversion,Format Conversion>> and
<<textures-texel-replacement,Texel Replacement>> sections (public
issue 52).
* Add logic to generate spec boilerplate without using the 'git'
command-line client, needed when building from a tarball or another
source of the Vulkan tree rather than a cloned git repo. Remove
boilerplate as part of 'clean' target (public issue 195).
* Document that color writes and clears to unused attachments have no
effect for slink:VkClearAttachment and
elink:VkColorComponentFlagBits (public issue 198).
* Fixed flink:vkCmdExecuteCommands validity statement for
sname:VkCommandBufferInheritanceInfo::pname:framebuffer. If used, it
must match the framebuffer in the current renderpass instance
(public issue 226).
* Added valid usage language to require for all functions that set
dynamic state that the currently bound graphics pipeline has the
corresponding dynamic state enabled (public issue 235).
Internal Issues:
* Clarify for flink:vkEnumerateInstanceExtensionProperties, in the
<<extended-functionality-instance-extensions-and-devices, Instance
Extensions and Device Extensions>> section, and in the
<<glossary,Glossary>> section when functionality should be exposed
as an instance extension, as a device extension, or as both
(internal issue 109).
* Place WorkgroupSize in alphabetical order in the
<<interfaces-builtin-variables,Built-in Variables>> section
(internal issue 323).
* Corrects valid usage in vkEndRenderPass to only affect primary
render passes, as secondaries may be entirely within a render pass,
and should be able to be ended (previous language disallowed that)
(internal issue 338).
* Fix relational operator from <= to >= in the
<<features-extentperimagetype,Allowed Extent Values>> section
(internal issue 343).
* Disallow recursion under SPIR-V entry points in the
<<spirvenv-module-validation,Validation Rules within a Module>>
section (internal SPIR-V issue 37).
Other Commits:
* Use standard Python ElementTree package instead of lxml.etree in
header / validation layer / include autogeneration from XML,
reducing platform dependencies.

[[extended-functionality-instance-extensions-and-devices]]
=== Instance Extensions and Device Extensions
Because an instance extension can affect the operation of an instance and
any of its child objects, the decision to expose functionality as an instance
extension or as a device extension is not always clear.
This section provides some guidelines and rules for when to expose new
functionality as an instance extension, device extension, or both.
The decision is influenced by whether extension functionality affects
instance-level objects (e.g. instances and physical devices) and commands,
or device-level objects (e.g. logical devices, queues, and command buffers)
and commands, or both.
In some cases, the decision is clear:
* Functionality that is restricted to the instance-level must: be
implemented as an instance extension.
* Functionality that is restricted to the device-level must: be
implemented as an device extension.
In other cases, the decision is not so clear:
* Global functionality that affects the entire Vulkan API, including
instance and device-level objects and commands, should: be an instance
extension.
* Device-level functionality that contains physical-device queries, can: be
implemented as an instance extension.
If some part of an instance extension's functionality might not be available
on all physical devices, the extension should: provide a query to determine
which physical devices provide the functionality.
* For a set of global functionality that provides new instance-level and
device-level commands, and can: be enabled for a subset of devices, it is
recommended that the functionality be partitioned across two extensions--one
for the instance-level functionality, and one for the device-specific
functionality.
In this latter case, it is generally recommended that the two extensions have
unique names.
Examples of instance extensions include:
* Logging of debug messages by any enabled layers for all Vulkan commands.
* Functionality creating new objects which are direct children of an instance.
* Functionality creating new objects which are direct children of a
physical device and intended to work with any logical device created
from the physical device.
* Functionality adding new instance-level Vulkan commands that do not affect
any device-level commands.
[NOTE]
.Note
====
Instance extensions generally require support in the Vulkan loader.
This is especially true for commands that are dispatched from
instances and physical devices.
Additional information about supporting instance-level commands may be found
in the "Vulkan Loader Specification and Architecture Overview" document,
which may be found at the following web page:
* https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/blob/sdk-1.0.13/loader/LoaderAndLayerInterface.md
Please see the "Architectural overview of layers and loader" section for
information about how both instance-level and device-level commands are
supported and dispatched.
