 <p>While <code>CL_DEVICE_<wbr>UUID_<wbr>KHR</code> is specified to remain consistent across driver
 versions and system reboots, it is not intended to be usable as a
 serializable persistent identifier for a device.
 It may change when a device is physically added to, removed from, or moved
 to a different connector in a system while that system is powered down.
 Further, there is no reasonable way to verify with conformance testing that
 a given device retains the same UUID in a given system across all driver
 versions supported in that system.
 While implementations should make every effort to report consistent device
 UUIDs across driver versions, applications should avoid relying on the
 persistence of this value for uses other than identifying compatible devices
 for external object sharing purposes.</p>

 <a href="#_footnoteref_1">1</a>. OpenCL adopters must report a valid vendor ID for their implementation. If there is no valid PCI vendor ID defined for the physical device, implementations must obtain a Khronos vendor ID. This is a unique identifier greater than the largest PCI vendor ID (<code>0x10000</code>) and is representable by a <code>cl_uint</code>. Khronos vendor IDs are synchronized across APIs by utilizing Vulkan&#8217;s vk.xml as the central Khronos vendor ID registry. An ID must be reserved here prior to use in OpenCL, regardless of whether a vendor implements Vulkan. Only once the ID has been allotted may it be exposed to OpenCL by proposing a merge request against cl.xml, in the <code>main</code> branch of the OpenCL-Docs project. The merge must define a new enumerant by adding an <code>&lt;enum&gt;</code> tag to the <code>cl_khronos_<wbr>vendor_<wbr>id</code> <code>&lt;enums&gt;</code> tag, with the <code>&lt;value&gt;</code> attribute set as the acquired Khronos vendor ID. The <code>&lt;name&gt;</code> attribute must identify the vendor/adopter, and be of the form <code>CL_KHRONOS_VENDOR_ID_&lt;vendor&gt;</code>.

 <a href="#_footnoteref_2">2</a>. A kernel that uses an image argument with the write_only or read_write image qualifier may result in additional read_only images resources being created internally by an implementation. The internally created read_only image resources will count against the max supported read image arguments given by <code>CL_DEVICE_<wbr>MAX_<wbr>READ_<wbr>IMAGE_<wbr>ARGS</code>. Enqueuing a kernel that requires more images than the implementation can support will result in a <code>CL_OUT_<wbr>OF_<wbr>RESOURCES</code> error being returned.
