💾 zl3073x_flash_sectors — Kernel API Manual, section 9

okay bestie, so this one's a kernel function from the zl3073x driver (it lives in ./drivers/dpll/zl3073x, section 9 of the manual, if you're keeping track 🎀). It's the one that actually pushes your data into flash. Let's get into it ✨

✨ SYNOPSIS ✨

int zl3073x_flash_sectors (struct zl3073x_dev *zldev , const char
*component , u32 page , u32 addr , const void *data , size_t size ,
struct netlink_ext_ack *extack );

no cap, that's the whole signature — copy it exactly, don't go "fixing" the spacing, the kernel does not want your help 💅

🫶 ARGUMENTS 🫶

  • zldev — the zl3073x device structure. like, the device you're talking to. main character energy 🎀
  • component — the component name. just a name, she's labels 💜
  • page — the destination flash page. where the data is headed 🦋
  • addr — the device memory address to load data at. the exact spot, no vibes-based guessing 🌸
  • data — pointer to the data to be flashed. the payload, the moment, the whole point 💅
  • size — size of data. yes it's bytes, and yes you need it right 😭
  • extack — netlink extack pointer to report errors. so when things go sideways, this is the one that tells everyone 📣

🔥 DESCRIPTION 🔥

So what does this icon actually do? She flashes the given data — size bytes of it, from data — into the internal flash memory block, and that block starts at page page. ⭐

The important ~vibe~ here: this function uses the sector flash method. Which means it has to take into account the flash sector size reported by the flashing utility. Not optional, not a suggestion, it literally has to. 🙈

And the way it handles that is honestly kind of slay? Your input data gets spliced into blocks according to that sector size, and then each of those blocks is flashed separately. one block at a time, no chaotic all-at-once nonsense 💅✨

🌈 RETURN 🌈

  • 0 on success — we love a win 👑
  • <0 on error — and it will be a negative number, so like, check it, bestie 😭

okay bye ily, this page came from ./drivers/dpll/zl3073x, dated October 2026 — like she's from the future, iconic behavior honestly 💜🌸
