+ * 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.

+ * Memory allocator
+ * ----------------
+ *
+ * Area [0; AreaSize) contains only the data, control structures are separate.
+ * Block sizes are power of 2: 32B, ..., 1MB
+ * Area size can be anything and will be divided initially to largest possible free blocks.
+ *
+ * The entire area is described by a list of 32 bit block descriptors:
+ * * bits 0..3 - order, which is log2 size of the block - 5: 2^(0+5) ... 2^(15+5) == 32B .. 1MB
+ * * bit 4 - 1 for free blocks.
+ * * bits 5..31 - block offset.
+ *
+ * 31 ... 5 | 4 | 3 ... 0
+ * offset F order
+ *
+ * There is a sorted collection of all block descriptors
+ * (key is the block offset, bits 0...4 do not interfere with sorting).
+ * Also there are lists of free blocks for each size for fast allocation.
+ *
+ *
+ * Implementation
+ * --------------
+ *
+ * The blocks collection is a sorted linear list.
+ *
+ * Initially the entire area consists of one or more largest blocks followed by smaller blocks:
+ * * 100B area - 64B block with descriptor: 0x00000011
+ * 32B block with descriptor: 0x00000030
+ * 4B unused
+ * * 64K area - one 64K block with descriptor: 0x0000001C
+ * * 512K area - one 512K block with descriptor: 0x0000001F
+ *
+ * When allocating a new block:
+ * * larger free blocks are splitted when there are no smaller free blocks;
+ * * smaller free blocks are merged if they can build a requested larger block.
