* struct iwl_cfg
|
|
* @fw_name_pre: Firmware filename prefix. The api version and extension
|
|
* (.ucode) will be added to filename before loading from disk. The
|
|
* filename is constructed as fw_name_pre<api>.ucode.
|
|
* @ucode_api_max: Highest version of uCode API supported by driver.
|
|
* @ucode_api_min: Lowest version of uCode API supported by driver.
|
|
*
|
|
* We enable the driver to be backward compatible wrt API version. The
|
|
* driver specifies which APIs it supports (with @ucode_api_max being the
|
|
* highest and @ucode_api_min the lowest). Firmware will only be loaded if
|
|
* it has a supported API version. The firmware's API version will be
|
|
* stored in @iwl_priv, enabling the driver to make runtime changes based
|
|
* on firmware version used.
|
|
*
|
|
* For example,
|
|
* if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
|
|
* Driver interacts with Firmware API version >= 2.
|
|
* } else {
|
|
* Driver interacts with Firmware API version 1.
|
|
* }
|
|
*
|
|
* The ideal usage of this infrastructure is to treat a new ucode API
|
|
* release as a new hardware revision. That is, through utilizing the
|
|
* iwl_hcmd_utils_ops etc. we accommodate different command structures
|
|
* and flows between hardware versions (4965/5000) as well as their API
|
|
* versions.
