+ *
+ * The command queue is a queue of RPCs that are sent from the driver to the
+ * GSP. The status queue is a queue of messages/responses from GSP-RM to the
+ * driver. Although the driver allocates memory for both queues, the command
+ * queue is owned by the driver and the status queue is owned by GSP-RM. In
+ * addition, the headers of the two queues must not share the same 4K page.
+ *
+ * Each queue is prefixed with this data structure. The idea is that a queue
+ * and its header are written to only by their owner. That is, only the
+ * driver writes to the command queue and command queue header, and only the
+ * GSP writes to the status (receive) queue and its header.
+ *
+ * This is enforced by the concept of "swapping" the RX pointers. This is
+ * why the 'flags' field must be set to 1. 'rxHdrOff' is how the GSP knows
+ * where the where the tail pointer of its status queue.
+ *
+ * When the driver writes a new RPC to the command queue, it updates writePtr.
+ * When it reads a new message from the status queue, it updates readPtr. In
+ * this way, the GSP knows when a new command is in the queue (it polls
+ * writePtr) and it knows how much free space is in the status queue (it
+ * checks readPtr). The driver never cares about how much free space is in
+ * the status queue.
+ *
+ * As usual, producers write to the head pointer, and consumers read from the
+ * tail pointer. When head == tail, the queue is empty.
+ *
+ * So to summarize:
+ * command.writePtr = head of command queue
+ * command.readPtr = tail of status queue
+ * status.writePtr = head of status queue
+ * status.readPtr = tail of command queue

+ * nvkm_gsp_radix3_sg - build a radix3 table from a S/G list
+ *
+ * The GSP uses a three-level page table, called radix3, to map the firmware.
+ * Each 64-bit "pointer" in the table is either the bus address of an entry in
+ * the next table (for levels 0 and 1) or the bus address of the next page in
+ * the GSP firmware image itself.
+ *
+ * Level 0 contains a single entry in one page that points to the first page
+ * of level 1.
+ *
+ * Level 1, since it's also only one page in size, contains up to 512 entries,
+ * one for each page in Level 2.
+ *
+ * Level 2 can be up to 512 pages in size, and each of those entries points to
+ * the next page of the firmware image. Since there can be up to 512*512
+ * pages, that limits the size of the firmware to 512*512*GSP_PAGE_SIZE = 1GB.
+ *
+ * Internally, the GSP has its window into system memory, but the base
+ * physical address of the aperture is not 0. In fact, it varies depending on
+ * the GPU architecture. Since the GPU is a PCI device, this window is
+ * accessed via DMA and is therefore bound by IOMMU translation. The end
+ * result is that GSP-RM must translate the bus addresses in the table to GSP
+ * physical addresses. All this should happen transparently.
+ *
+ * Returns 0 on success, or negative error code
+ *
+ * See kgspCreateRadix3_IMPL
