+ * The DRM driver stack is designed to work with cache coherent devices
+ * only, but permits an optimization to be enabled in some cases, where
+ * for some buffers, both the CPU and the GPU use uncached mappings,
+ * removing the need for DMA snooping and allocation in the CPU caches.
+ *
+ * The use of uncached GPU mappings relies on the correct implementation
+ * of the PCIe NoSnoop TLP attribute by the platform, otherwise the GPU
+ * will use cached mappings nonetheless. On x86 platforms, this does not
+ * seem to matter, as uncached CPU mappings will snoop the caches in any
+ * case. However, on ARM and arm64, enabling this optimization on a
+ * platform where NoSnoop is ignored results in loss of coherency, which
+ * breaks correct operation of the device. Since we have no way of
+ * detecting whether NoSnoop works or not, just disable this
+ * optimization entirely for ARM and arm64.
