+ * Pixels are arranged in Groups of Bytes (GOBs). GOB size and layout varies

+ *
+ * 4:4 - Must be 1, to indicate block-linear layout. Necessary for
+ * compatibility with the existing
+ * DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK()-based modifiers.
+ *
+ * 8:5 - Reserved (To support 3D-surfaces with variable log2(depth) block
+ * size). Must be zero.
+ *
+ * Note there is no log2(width) parameter. Some portions of the
+ * hardware support a block width of two gobs, but it is impractical
+ * to use due to lack of support elsewhere, and has no known
+ * benefits.
+ *
+ * 11:9 - Reserved (To support 2D-array textures with variable array stride
+ * in blocks, specified via log2(tile width in blocks)). Must be
+ * zero.
+ *
+ * 19:12 k Page Kind. This value directly maps to a field in the page
+ * tables of all GPUs >= NV50. It affects the exact layout of bits
+ * in memory and can be derived from the tuple
+ *
+ * (format, GPU model, compression type, samples per pixel)
+ *
+ * Where compression type is defined below. If GPU model were
+ * implied by the format modifier, format, or memory buffer, page
+ * kind would not need to be included in the modifier itself, but
+ * since the modifier should define the layout of the associated
+ * memory buffer independent from any device or other context, it
+ * must be included here.
+ *
+ * 21:20 g GOB Height and Page Kind Generation. The height of a GOB changed
+ * starting with Fermi GPUs. Additionally, the mapping between page
+ * kind and bit layout has changed at various points.
+ *
+ * 0 = Gob Height 8, Fermi - Volta, Tegra K1+ Page Kind mapping
+ * 1 = Gob Height 4, G80 - GT2XX Page Kind mapping
+ * 2 = Gob Height 8, Turing+ Page Kind mapping
+ * 3 = Reserved for future use.
+ *
+ * 22:22 s Sector layout. On Tegra GPUs prior to Xavier, there is a further
+ * bit remapping step that occurs at an even lower level than the
+ * page kind and block linear swizzles. This causes the layout of
+ * surfaces mapped in those SOC's GPUs to be incompatible with the
+ * equivalent mapping on other GPUs in the same system.
+ *
+ * 0 = Tegra K1 - Tegra Parker/TX2 Layout.
+ * 1 = Desktop GPU and Tegra Xavier+ Layout
+ *
+ * 25:23 c Lossless Framebuffer Compression type.
