ice_read_64b_phy_reg_e82x(9)
π ice_read_64b_phy_reg_e82x(9) β from the Kernel API Manual, bestie π
okay so picture this: it's a kernel API manual page, the star of the show is ice_read_64b_phy_reg_e82x, and I'm here to translate it into human. sit down, hydrate, let's go β¨
πΈ NAME πΈ
ice_read_64b_phy_reg_e82x β read a 64bit value from PHY registers π yeah that's literally the whole gig. one job. reads the big number. slays.
β¨ SYNOPSIS β¨
int ice_read_64b_phy_reg_e82x (struct ice_hw *hw , u8 port , u16
low_addr , u64 *val );
look at her. returns an int, takes four things, no notes. π
π¦ ARGUMENTS π¦
hwβ pointer to the HW struct. this is the main character, the hardware context, everything flows through her π«Άportβ the PHY port you're reading from. which port bestie. pick one.low_addrβ offset of the lower register you're reading from. note the word lower, we come back to that πvalβ on return, the contents of the 64bit value from the PHY registers. she's an output param, she comes back full of data, that's the whole point π
π DESCRIPTION π
so what does she actually do. she reads the two registers associated with a 64bit value and returns it in the val pointer. two registers, one number, classic two-halves-of-one-brain situation π§ β¨
the offset always specifies the lower register offset to use β that's the one you hand her. the high offset is looked up for you, like a good friend who already knows where the other half lives, no cap.
π¨ important vibe check: this function only operates on registers known to be two parts of a 64bit value. she is not out here guessing, she is not out here exploring. if it's not a known 64bit pair, that's not her problem, don't @ her π
π§ SEE ALSO π§
the friend group. the whole group chat. genuinely iconic how many names are in here, I'm not skipping a single one, we ride for all of them π
