STRUCT PANTHOR_FW_SECTION(9)

🎀 struct panthor_fw_section — FW section 💖

okay so welcome to the struct panthor_fw_section(9) page bestie, straight out of the Kernel API Manual ✨ this one's short and sweet — it's literally the lil struct that holds one FW section, and we're gonna go through every single member, no skips, no cap 🫶

✨ SYNOPSIS ✨

struct panthor_fw_section {
    struct list_head node;
    u32 flags;
    struct panthor_kernel_bo *mem;
    const char *name;
    struct {
      const void *buf;
      size_t size;
    } data;
 };

that's the whole thing 💅 she's compact and she knows it.

🌸 Members 🌸

• node — the little bookkeeping hook 🎀 it's what keeps track of the FW sections, so like the list knows who's who.
• flags — section flags, exactly as encoded in the FW binary. no editing, no vibes-based interpretation, just what the binary said 👑
• mem — section memory. that's her home 🏠
• name — the name of the section, as specified in the binary.

heads up bestie: this one can be NULL 😭 so don't go dereferencing it without a vibe check first.

• data — the initial data copied to the FW memory.

and why do we keep it around? because we keep data so we can reload sections after a reset 🔥 iconic behavior honestly, very prepared of her.
