/*
|
||
|
|
* We need to know as early as possible if we're going to use GuC or not to
|
||
|
|
* take the correct setup paths. Additionally, once we've started loading the
|
||
|
|
* GuC, it is unsafe to keep executing without it because some parts of the HW,
|
||
|
|
* a subset of which is not cleaned on GT reset, will start expecting the GuC FW
|
||
|
|
* to be running.
|
||
|
|
* To solve both these requirements, we commit to using the microcontrollers if
|
||
|
|
* the relevant modparam is set and the blobs are found on the system. At this
|
||
|
|
* stage, the only thing that can stop us from attempting to load the blobs on
|
||
|
|
* the HW and use them is a fundamental issue (e.g. no memory for our
|
||
|
|
* structures); if we hit such a problem during driver load we're broken even
|
||
|
|
* without GuC, so there is no point in trying to fall back.
|
||
|
|
*
|
||
|
|
* Given the above, we can be in one of 4 states, with the last one implying
|
||
|
|
* we're committed to using the microcontroller:
|
||
|
|
* - Not supported: not available in HW and/or firmware not defined.
|
||
|
|
* - Supported: available in HW and firmware defined.
|
||
|
|
* - Wanted: supported + enabled in modparam.
|
||
|
|
* - In use: wanted + firmware found on the system and successfully fetched.
