- * DOC: GSP message queue element
- *
- * https://github.com/NVIDIA/open-gpu-kernel-modules/blob/535/src/nvidia/inc/kernel/gpu/gsp/message_queue_priv.h
- *
- * The GSP command queue and status queue are message queues for the
- * communication between software and GSP. The software submits the GSP
- * RPC via the GSP command queue, GSP writes the status of the submitted
- * RPC in the status queue.
- *
- * A GSP message queue element consists of three parts:
- *
- * - message element header (struct r535_gsp_msg), which mostly maintains
- * the metadata for queuing the element.
- *
- * - RPC message header (struct nvfw_gsp_rpc), which maintains the info
- * of the RPC. E.g., the RPC function number.
- *
- * - The payload, where the RPC message stays. E.g. the params of a
- * specific RPC function. Some RPC functions also have their headers
- * in the payload. E.g. rm_alloc, rm_control.
- *
- * The memory layout of a GSP message element can be illustrated below::
- *
- * +------------------------+
- * | Message Element Header |
- * | (r535_gsp_msg) |
- * | |
- * | (r535_gsp_msg.data) |
- * | | |
- * |----------V-------------|
- * | GSP RPC Header |
- * | (nvfw_gsp_rpc) |
- * | |
- * | (nvfw_gsp_rpc.data) |
- * | | |
- * |----------V-------------|
- * | Payload |
- * | |
- * | header(optional) |
- * | params |
- * +------------------------+
- *
- * The max size of a message queue element is 16 pages (including the
- * headers). When a GSP message to be sent is larger than 16 pages, the
- * message should be split into multiple elements and sent accordingly.
- *
- * In the bunch of the split elements, the first element has the expected
- * function number, while the rest of the elements are sent with the
- * function number NV_VGPU_MSG_FUNCTION_CONTINUATION_RECORD.
- *
- * GSP consumes the elements from the cmdq and always writes the result
- * back to the msgq. The result is also formed as split elements.
- *
- * Terminology:
- *
- * - gsp_msg(msg): GSP message element (element header + GSP RPC header +
- * payload)
- * - gsp_rpc(rpc): GSP RPC (RPC header + payload)
- * - gsp_rpc_buf: buffer for (GSP RPC header + payload)
- * - gsp_rpc_len: size of (GSP RPC header + payload)
- * - params_size: size of params in the payload
- * - payload_size: size of (header if exists + params) in the payload

-/**
- * DOC: Receive a GSP message queue element
- *
- * Receiving a GSP message queue element from the message queue consists of
- * the following steps:
- *
- * - Peek the element from the queue: r535_gsp_msgq_peek().
- * Peek the first page of the element to determine the total size of the
- * message before allocating the proper memory.
- *
- * - Allocate memory for the message.
- * Once the total size of the message is determined from the GSP message
- * queue element, the caller of r535_gsp_msgq_recv() allocates the
- * required memory.
- *
- * - Receive the message: r535_gsp_msgq_recv().
- * Copy the message into the allocated memory. Advance the read pointer.
- * If the message is a large GSP message, r535_gsp_msgq_recv() calls
- * r535_gsp_msgq_recv_one_elem() repeatedly to receive continuation parts
- * until the complete message is received.
- * r535_gsp_msgq_recv() assembles the payloads of cotinuation parts into
- * the return of the large GSP message.
- *
- * - Free the allocated memory: r535_gsp_msg_done().
- * The user is responsible for freeing the memory allocated for the GSP
- * message pages after they have been processed.

+ * DOC: GSP message queue element
+ *
+ * https://github.com/NVIDIA/open-gpu-kernel-modules/blob/535/src/nvidia/inc/kernel/gpu/gsp/message_queue_priv.h
+ *
+ * The GSP command queue and status queue are message queues for the
+ * communication between software and GSP. The software submits the GSP
+ * RPC via the GSP command queue, GSP writes the status of the submitted
+ * RPC in the status queue.
+ *
+ * A GSP message queue element consists of three parts:
+ *
+ * - message element header (struct r535_gsp_msg), which mostly maintains
+ * the metadata for queuing the element.
+ *
+ * - RPC message header (struct nvfw_gsp_rpc), which maintains the info
+ * of the RPC. E.g., the RPC function number.
+ *
+ * - The payload, where the RPC message stays. E.g. the params of a
+ * specific RPC function. Some RPC functions also have their headers
+ * in the payload. E.g. rm_alloc, rm_control.
+ *
+ * The memory layout of a GSP message element can be illustrated below::
+ *
+ * +------------------------+
+ * | Message Element Header |
+ * | (r535_gsp_msg) |
+ * | |
+ * | (r535_gsp_msg.data) |
+ * | | |
+ * |----------V-------------|
+ * | GSP RPC Header |
+ * | (nvfw_gsp_rpc) |
+ * | |
+ * | (nvfw_gsp_rpc.data) |
+ * | | |
+ * |----------V-------------|
+ * | Payload |
+ * | |
+ * | header(optional) |
+ * | params |
+ * +------------------------+
+ *
+ * The max size of a message queue element is 16 pages (including the
+ * headers). When a GSP message to be sent is larger than 16 pages, the
+ * message should be split into multiple elements and sent accordingly.
+ *
+ * In the bunch of the split elements, the first element has the expected
+ * function number, while the rest of the elements are sent with the
+ * function number NV_VGPU_MSG_FUNCTION_CONTINUATION_RECORD.
+ *
+ * GSP consumes the elements from the cmdq and always writes the result
+ * back to the msgq. The result is also formed as split elements.
+ *
+ * Terminology:
+ *
+ * - gsp_msg(msg): GSP message element (element header + GSP RPC header +
+ * payload)
+ * - gsp_rpc(rpc): GSP RPC (RPC header + payload)
+ * - gsp_rpc_buf: buffer for (GSP RPC header + payload)
+ * - gsp_rpc_len: size of (GSP RPC header + payload)
+ * - params_size: size of params in the payload
+ * - payload_size: size of (header if exists + params) in the payload

+ * DOC: Receive a GSP message queue element
+ *
+ * Receiving a GSP message queue element from the message queue consists of
+ * the following steps:
+ *
+ * - Peek the element from the queue: r535_gsp_msgq_peek().
+ * Peek the first page of the element to determine the total size of the
+ * message before allocating the proper memory.
+ *
+ * - Allocate memory for the message.
+ * Once the total size of the message is determined from the GSP message
+ * queue element, the caller of r535_gsp_msgq_recv() allocates the
+ * required memory.
+ *
+ * - Receive the message: r535_gsp_msgq_recv().
+ * Copy the message into the allocated memory. Advance the read pointer.
+ * If the message is a large GSP message, r535_gsp_msgq_recv() calls
+ * r535_gsp_msgq_recv_one_elem() repeatedly to receive continuation parts
+ * until the complete message is received.
+ * r535_gsp_msgq_recv() assembles the payloads of cotinuation parts into
+ * the return of the large GSP message.
+ *
+ * - Free the allocated memory: r535_gsp_msg_done().
+ * The user is responsible for freeing the memory allocated for the GSP
+ * message pages after they have been processed.
