STRUCT FCOE_PERCPU_S(9)
π struct fcoe_percpu_s(9)
okay bestie, welcome to the Kernel API Manual β¨ β yes, we're literally reading kernel docs together, this is our Hot Girl Systems Programming era π. Today's main character is struct fcoe_percpu_s, and it's giving "the context for FCoE receive thread(s)" π¦. That's the whole vibe β it's the little per-CPU hangout spot where FCoE receive threads keep their stuff. Periodt.
πΈ SYNOPSIS πΈ
struct fcoe_percpu_s {
struct task_struct *kthread;
struct work_struct work;
struct sk_buff_head fcoe_rx_list;
struct page *crc_eof_page;
int crc_eof_offset;
local_lock_t lock;
};
no cap, that's the whole struct π. Copy it exactly, don't get cute with it, bestie β the compiler does not think typos are iconic π.
β¨ Members β¨
okay so let's meet the squad, one member at a time π«Ά:
kthreadβ the thread context. it's lowkey only used bybnx2fcπ (yes, it's a whole thing, iykyk).workβ the work item, and this one's used byfcoeπ .fcoe_rx_listβ the queue of pending packets to process. the little inbox where packets wait their turn, main character energy fr fr π.crc_eof_pageβ the memory page for calculating frame trailer CRCs β¨. it's the scratch page, it's doing the math.crc_eof_offsetβ the offset into the CRC page pointing to available memory for a new trailer πΈ. like, where's the next free slot? this int knows.lockβ local lock for members of this struct π. keeps the whole squad from stepping on each other, we love a boundaries moment.
π SEE ALSO π
go read these next, bestie, they're all in Kernel file ./include/scsi/libfcoe.h π:
enum fip_state(9)struct fcoe_ctlr(9)fcoe_ctlr_priv(9)struct fcoe_fcf(9)struct fcoe_rport(9)is_fip_mode(9)struct fcoe_port(9)fcoe_get_netdev(9)struct fcoe_netdev_mapping(9)
that's the whole reading list, no skipping ππ.
and that's a wrap on our girl π this page lives in ./include/scsi, dated October 2026, and it's filed under struct fcoe_percpu_s(9) β slay, ate, no notes ππ¦β¨
