Syscon Thermal Configs
Description
The thermal config is an area inside syscon where are stored the settings related with fan speed control
In Mullion syscon series is located at offset 0x3300, length 0x200, and is "protected" by a checksum located at 0x34FE (the last 2 bytes of the 0x200 bytes chunk)
In Sherwood syscon series is located at 0x250, we consider it have a length of 0x200 too, and is "protected" by a checksum located at 0x7FE (the last 2 bytes of a 0x800 bytes chunk including the thermal config and other eeprom areas)
The thermal configs are specific for a motherboard model, usually all motherboards of the same model shares the same thermal config, but not always, it has been found different thermal configs used in the same motherboard
Official thermal configs
This configs are orientative, the purpose of this list is to collect all the officials for a better understanding of them, if you find other official config not in the list please add it, but dont publish here any custom config, the scope of this list is limited only to the original settings used by sony
This wiki page is inspired by this thread, the coordinate graph images from that thread are made by me (sandungas) and eventually i will upload new versions of them to wiki, but not yet because at the time of writing this (may 2021) are not the final version
When talking about thermal configs is very convenient to use an unique identifyers for them, and the checksum "protection" used by syscon is perfect for that purpose, in Mullion series this is specially accurate because that cheksum is the checksum of the exact thermal config (except the last 2 bytes). In Sherwood is not so easy because the cheksum includes other areas of the eeprom so is not exactly an unique identifyer of the thermal config, for that reason in the Mullion thermal configs is indicated the CRC32 (of the 0x200 bytes area only, calculated in PC)
