+ * GK20A does not have dedicated video memory, and to accurately represent this
+ * fact Nouveau will not create a RAM device for it. Therefore its instmem
+ * implementation must be done directly on top of system memory, while
+ * preserving coherency for read and write operations.
+ *
+ * Instmem can be allocated through two means:
+ * 1) If an IOMMU unit has been probed, the IOMMU API is used to make memory
+ *    pages contiguous to the GPU. This is the preferred way.
+ * 2) If no IOMMU unit is probed, the DMA API is used to allocate physically
+ *    contiguous memory.
+ *
+ * In both cases CPU read and writes are performed by creating a write-combined
+ * mapping. The GPU L2 cache must thus be flushed/invalidated when required. To
+ * be conservative we do this every time we acquire or release an instobj, but
+ * ideally L2 management should be handled at a higher level.
+ *
