hv: Add hyperv.h to uapi headers
This patch adds the hyperv.h header to the uapi folder, and adds it to the Kbuild file. Doing this enables compiling userspace Hyper-V tools using the installed headers. Version 2: Split UAPI parts into new header, instead of duplicating. Signed-off-by: Bjarke Istrup Pedersen <gurligebis@gentoo.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

137 * In Linux, we implement the KVP functionality in two components:
138 * 1) The kernel component which is packaged as part of the hv_utils driver
139 * is responsible for communicating with the host and responsible for
140 * implementing the host/guest protocol. 2) A user level daemon that is
141 * responsible for data gathering.
142 *
143 * Host/Guest Protocol: The host iterates over an index and expects the guest
144 * to assign a key name to the index and also return the value corresponding to
145 * the key. The host will have atmost one KVP transaction outstanding at any
146 * given point in time. The host side iteration stops when the guest returns
147 * an error. Microsoft has specified the following mapping of key names to
148 * host specified index:
149 *
150 * Index Key Name
151 * 0 FullyQualifiedDomainName
152 * 1 IntegrationServicesVersion
153 * 2 NetworkAddressIPv4
154 * 3 NetworkAddressIPv6
155 * 4 OSBuildNumber
156 * 5 OSName
157 * 6 OSMajorVersion
158 * 7 OSMinorVersion
159 * 8 OSVersion
160 * 9 ProcessorArchitecture
161 *
162 * The Windows host expects the Key Name and Key Value to be encoded in utf16.
163 *
164 * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
165 * data gathering functionality in a user mode daemon. The user level daemon
166 * is also responsible for binding the key name to the index as well. The
167 * kernel and user-level daemon communicate using a connector channel.
168 *
169 * The user mode component first registers with the
170 * the kernel component. Subsequently, the kernel component requests, data
171 * for the specified keys. In response to this message the user mode component
172 * fills in the value corresponding to the specified key. We overload the
173 * sequence field in the cn_msg header to define our KVP message types.
174 *
175 *
176 * The kernel component simply acts as a conduit for communication between the
177 * Windows host and the user-level daemon. The kernel component passes up the
178 * index received from the Host to the user-level daemon. If the index is
179 * valid (supported), the corresponding key as well as its
180 * value (both are strings) is returned. If the index is invalid
181 * (not supported), a NULL key string is returned.

205 * An older daemon will always be supported on a newer driver.
206 * A given user level daemon will require a minimal version of the

209 * (this can happen when we have a user level daemon that is more

199 * Here is the level of compatibility
200 * (between the user level daemon and the kernel KVP driver) that we
201 * will implement:
202 *
203 * An older daemon will always be supported on a newer driver.
204 * A given user level daemon will require a minimal version of the
205 * kernel driver.
206 * If we cannot handle the version differences, we will fail gracefully
207 * (this can happen when we have a user level daemon that is more
208 * advanced than the KVP driver.
209 *
210 * We will use values used in this handshake for determining if we have
211 * workable user level daemon and the kernel driver. We begin by taking the
212 * registration opcode out of the KVP opcode namespace. We will however,
213 * maintain compatibility with the existing user-level daemon code.
