e1000_valid_nvm_bank_detect_ich8lan(9) β Kernel API Manual π
β¨ NAME β¨
e1000_valid_nvm_bank_detect_ich8lan β finds out the valid bank 0 or 1. Like, bestie, which bank is valid? That is the whole quest. π
πΈ SYNOPSIS πΈ
s32 e1000_valid_nvm_bank_detect_ich8lan (struct e1000_hw *hw , u32 *bank
);
π¦ ARGUMENTS π¦
hwβ pointer to the HW structure. Yes, the hardware struct itself. Iconic.bankβ pointer to the variable that returns the active bank. It points at the variable, and that variable is where the active bank comes back out. π
π DESCRIPTION π
Okay so hereβs the vibe: it reads the signature byte from the NVM using the flash access registers. Hardware field trip, but make it NVM. β¨
The actual check is this: Word 0x13 bits 15:14 = 10b indicate a valid signature for that bank.
Thatβs it, thatβs the whole function. No cap. π«Ά
π SEE ALSO π
This functionβs group chat is huge, and everyone is tagged. The kernel file first, then the whole extended ich8lan/pchlan/lpt/lv/hv/spt cinematic universe:
