+/**
+ * Basic mechanism for the HGSMI is to prepare and pass data buffer to the host and the guest.
+ * Data inside these buffers are opaque for the HGSMI and are interpreted by higher levels.
+ *
+ * Every shared memory buffer passed between the guest/host has the following structure:
+ *
+ * HGSMIBUFFERHEADER header;
+ * uint8_t data[header.u32BufferSize];
+ * HGSMIBUFFERTAIL tail;
+ *
+ * Note: Offset of the 'header' in the memory is used for virtual hardware IO.
+ *
+ * Buffers are verifyed using the offset and the content of the header and the tail,
+ * which are constant during a call.
+ *
+ * Invalid buffers are ignored.
+ *
+ * Actual 'data' is not verifyed, as it is expected that the data can be changed by the
+ * called function.
+ *
+ * Since only the offset of the buffer is passed in a IO operation, the header and tail
+ * must contain:
+ * * size of data in this buffer;
+ * * checksum for buffer verification.
+ *
+ * For segmented transfers:
+ * * the sequence identifier;
+ * * offset of the current segment in the sequence;
+ * * total bytes in the transfer.
+ *
+ * Additionally contains:
+ * * the channel ID;
+ * * the channel information.
