+ * Note that this all changes on discrete platforms, starting from DG1, the
+ * set/get caching is no longer supported, and is now rejected. Instead the CPU
+ * caching attributes(WB vs WC) will become an immutable creation time property
+ * for the object, along with the GTT caching level. For now we don't expose any
+ * new uAPI for this, instead on DG1 this is all implicit, although this largely
+ * shouldn't matter since DG1 is coherent by default(without any way of
+ * controlling it).
+ *
+ * Implicit caching rules, starting from DG1:
+ *
+ * - If any of the object placements (see &drm_i915_gem_create_ext_memory_regions)
+ * contain I915_MEMORY_CLASS_DEVICE then the object will be allocated and
+ * mapped as write-combined only.
+ *
+ * - Everything else is always allocated and mapped as write-back, with the
+ * guarantee that everything is also coherent with the GPU.
+ *
+ * Note that this is likely to change in the future again, where we might need
+ * more flexibility on future devices, so making this all explicit as part of a
+ * new &drm_i915_gem_create_ext extension is probable.
+ *
+ * Side note: Part of the reason for this is that changing the at-allocation-time CPU
+ * caching attributes for the pages might be required(and is expensive) if we
+ * need to then CPU map the pages later with different caching attributes. This
+ * inconsistent caching behaviour, while supported on x86, is not universally
+ * supported on other architectures. So for simplicity we opt for setting
+ * everything at creation time, whilst also making it immutable, on discrete
+ * platforms.

+ * not be an empty string.
+ * @version: Driver version string; may be an empty string
+ * @fw_version: Firmware version string; may be an empty string
+ * @erom_version: Expansion ROM version string; may be an empty string
+ * @bus_info: Device bus address. This should match the dev_name()
+ * string for the underlying bus device, if there is one. May be
+ * an empty string.
+ * @reserved2: Reserved for future use; see the note on reserved space.
+ * @n_priv_flags: Number of flags valid for %ETHTOOL_GPFLAGS and
+ * %ETHTOOL_SPFLAGS commands; also the number of strings in the
+ * %ETH_SS_PRIV_FLAGS set
+ * @n_stats: Number of u64 statistics returned by the %ETHTOOL_GSTATS
+ * command; also the number of strings in the %ETH_SS_STATS set
+ * @testinfo_len: Number of results returned by the %ETHTOOL_TEST
+ * command; also the number of strings in the %ETH_SS_TEST set
+ * @eedump_len: Size of EEPROM accessible through the %ETHTOOL_GEEPROM
+ * and %ETHTOOL_SEEPROM commands, in bytes
+ * @regdump_len: Size of register dump returned by the %ETHTOOL_GREGS
+ * command, in bytes
+ *
+ * Users can use the %ETHTOOL_GSSET_INFO command to get the number of
+ * strings in any string set (from Linux 2.6.34).
+ *
+ * Drivers should set at most @driver, @version, @fw_version and
+ * @bus_info in their get_drvinfo() implementation. The ethtool
+ * core fills in the other fields using other driver operations.
