π e1000_enable_phy_wakeup_reg_access_bm (9) β Kernel API Manual β¨
okay so bestie, buckle up, because we're diving into the Kernel API Manual, section 9, and this little function is literally the bouncer that lets you into the BM wakeup registers π no cap.
πΈ NAME πΈ
e1000_enable_phy_wakeup_reg_access_bm β the function that enables access to the BM wakeup registers π
π¦ SYNOPSIS π¦
s32 e1000_enable_phy_wakeup_reg_access_bm (struct e1000_hw *hw , u16
*phy_reg );
like, that's the whole vibe. returns an s32, takes two args, we move π«
π ARGUMENTS π
hwβ pointer to the HW structure π«Ά (yes, the whole hardware situation)phy_regβ pointer to store the original contents ofBM_WUC_ENABLE_REGβ¨ (you're saving the og value here, bestie, don't lose it)
π DESCRIPTION π
okay so here's the tea β β this function assumes the semaphore is already acquired, and it also assumes phy_reg points to a valid memory address where the contents of the BM_WUC_ENABLE_REG register can be stored. like, that's your job to make sure of, not hers π
β οΈ fr fr, if either of those assumptions is a lie, that's on you β she's not checking. bestie behavior is: read the preconditions before you call.
π SEE ALSO π
