i40e_led_is_mine(9)
π‘ i40e_led_is_mine β the "is this LED mine??" helper
okay so bestie, welcome to i40e_led_is_mine(9) from the Kernel API Manual (section 9, obviously π
). this is a tiny little helper in the i40e driver and honestly it's giving "small but essential" energy. let's get into it β¨
πΈ NAME
i40e_led_is_mine β a helper to find the matching led π
π¦ SYNOPSIS
u32 i40e_led_is_mine (struct i40e_hw *hw , int idx );
that's it. that's the whole signature. no cap, it's lowkey adorable π«Ά
π ARGUMENTS
hwβ a pointer to thehwstruct π like, the whole hardware situation lives in here, and you're handing it over.idxβ an index into the GPIO registers β this is the little number that tells it which slot to peek at.
π₯ RETURN
0if there's no match π- otherwise, the value of the
GPIO_CTLregister π
so basically: zero means "nope, not yours", anything else means "yep, here's the goods" β¨
ngl the whole "0 means no match" thing is literally the classic C move β remember it, bestie, or you're gonna have a bad time π
π SEE ALSO
