* DOC: GuC Firmware Layout
|
|
*
|
|
* The GuC firmware layout looks like this:
|
|
*
|
|
* +-------------------------------+
|
|
* | guc_css_header |
|
|
* | contains major/minor version |
|
|
* +-------------------------------+
|
|
* | uCode |
|
|
* +-------------------------------+
|
|
* | RSA signature |
|
|
* +-------------------------------+
|
|
* | modulus key |
|
|
* +-------------------------------+
|
|
* | exponent val |
|
|
* +-------------------------------+
|
|
*
|
|
* The firmware may or may not have modulus key and exponent data. The header,
|
|
* uCode and RSA signature are must-have components that will be used by driver.
|
|
* Length of each components, which is all in dwords, can be found in header.
|
|
* In the case that modulus and exponent are not present in fw, a.k.a truncated
|
|
* image, the length value still appears in header.
|
|
*
|
|
* Driver will do some basic fw size validation based on the following rules:
|
|
*
|
|
* 1. Header, uCode and RSA are must-have components.
|
|
* 2. All firmware components, if they present, are in the sequence illustrated
|
|
* in the layout table above.
|
|
* 3. Length info of each component can be found in header, in dwords.
|
|
* 4. Modulus and exponent key are not required by driver. They may not appear
|
|
* in fw. So driver will load a truncated firmware in this case.
