369 | * We enable the driver to be backward compatible wrt API version. The | |
370 | * driver specifies which APIs it supports (with @ucode_api_max being the | |
371 | * highest and @ucode_api_min the lowest). Firmware will only be loaded if | |
372 | * it has a supported API version. The firmware's API version will be | |
373 | * stored in @iwl_priv, enabling the driver to make runtime changes based | |
374 | * on firmware version used. | |
375 | * | |
376 | * For example, | |
377 | * if (IWL_UCODE_API(priv->ucode_ver) >= 2) { | |
7cb1b088 | 378 | * Driver interacts with Firmware API version >= 2. |
a0987a8d | 379 | * } else { |
7cb1b088 | 380 | * Driver interacts with Firmware API version 1. |
a0987a8d RC |
381 | * } |
382 | * | |
383 | * The ideal usage of this infrastructure is to treat a new ucode API | |
384 | * release as a new hardware revision. That is, through utilizing the | |
385 | * iwl_hcmd_utils_ops etc. we accommodate different command structures | |
386 | * and flows between hardware versions (4965/5000) as well as their API | |
387 | * versions. | |
