+== Status
+
+Working Draft
+
+This is a preview extension specification, intended to provide early access to
+a feature for review and community feedback. When the feature matures, this
+specification may be released as a formal extension.
+
+Because the interfaces defined by this specification are not final and are
+subject to change they are not intended to be used by shipping software
+products.

+
+== Dependencies
+
+This extension is written against the SYCL 1.2.1 specification, Revision 6.
+
+== Overview
+
+OpenCL provides two functions for querying properties of a kernel:
+`clGetKernelInfo` is used for kernel properties that are device agnostic,
+whereas `clGetKernelWorkGroupInfo` is used for kernel and work-group properties
+that depend on a specific device. The name `clGetKernelWorkGroupInfo` doesn't
+convey the API's intended use explicitly, that is, queries for
+*device-specific* properties. In this sense, `clGetKernelWorkGroupInfo` is a
+misnomer for some uses of the API.
+
+SYCL inherited these names in the form of the queries `kernel::get_info` and
+`kernel::get_work_group_info`. This extension renames the latter (and its
+template arguments as appropriate) in order to align the query name with its
+functionality.
+
+== Modifications of SYCL 1.2.1 Specification
+
+=== Change Section 4.8.7 Kernel class
+
+==== Change `kernel` class interface
+
+Remove lines 29-31 (inclusive) from the `kernel` class interface:
+
+[source,c++,`sycl::kernel`,linenums]
+----
+template <info::kernel_work_group param>
+typename info::param_traits<info::kernel_work_group, param>::return_type
+get_work_group_info(const device &dev) const;
+----
+
+Add function overload `get_info` to the `kernel` class interface:
+
+[source,c++,`sycl::kernel`,linenums]
+----
+template <info::kernel_device_specific param>
+typename info::param_traits<info::kernel_device_specific, param>::return_type
+get_info(const device &dev) const;
+----
+
+==== Change table 4.83 Member functions of the Kernel class
+
+Remove row `get_work_group_info(const device &dev)`:
+
+[width="40%",frame="topbot",options="header,footer"]
+|======================
+|Member functions |Description
+|`template <info::kernel_work_group param>typename info::param_traits<info::kernel_work_group, param>::return_type get_work_group_info(const device &dev)const` |
+Query information from the work-group from a kernel using the info::kernel_work_group descriptor for a specific device
+|======================
+
+Add row `get_info(const device &dev)`:
+
+[width="40%",frame="topbot",options="header,footer"]
+|======================
+|Member functions |Description
+|`template <info::kernel_device_specific param>typename info::param_traits<info::kernel_device_specific, param>::return_type get_info(const device &dev)const` |
+Query information from a kernel using the info::kernel_device_specific descriptor for a specific device.
+|======================
+
+==== Change table 4.85 Kernel work-group information descriptors
+
+Rename table to: +Kernel device-specific information descriptors+.
+
+Replace all references to `info::kernel_work_group` with
+`info::kernel_device_specific`.
+
+==== Change A.5 Kernel Information Descriptors
+
+Rename `enum class kernel_work_group: int` to `enum class
+kernel_device_specific: int`.
+
+== Issues
+
+None.
