qcom_mdt_load(9)

📦 version 7.3.1, in nixpkgs unstable

💅 qcom_mdt_load(9) — like, the Kernel API Manual, bestie 🎀

okay so real quick, the manual name is qcom_mdt_load — that's the whole vibe of this page, it's the kernel API manual for it, and we're about to get into it 💖

✨ NAME ✨

qcom_mdt_load — loads the firmware whose header is loaded as fw. That's the whole job. She's a loader. Iconic behavior honestly 🫶

🌸 SYNOPSIS 🌸

int qcom_mdt_load (struct device *dev , const struct firmware *fw ,
const char *fw_name , int pas_id , void *mem_region , phys_addr_t
mem_phys , size_t mem_size , phys_addr_t *reloc_base );

eight arguments. EIGHT. not me counting them twice 😭 but like, she ate, we move.

🦋 ARGUMENTS 🦋

  • dev — the device handle, aka where you associate your resources. think of it as the friend you bring to the party so you're not standing alone 💀
  • fw — the firmware object for the mdt file. the actual goods.
  • fw_name — name of the firmware. it's used to construct the segment file names, so like... it does the naming math for you, no cap ✨
  • pas_id — the PAS identifier. that's it. that's the whole description. she's mysterious, she's lowkey giving main character energy 👑
  • mem_region — the allocated memory region you're loading the firmware into. that's the bucket 🪣
  • mem_phys — the physical address of that allocated memory region. phys_addr_t, so like, respect her type.
  • mem_size — the size of the allocated memory region, size_t flavored 🌈
  • reloc_base — the adjusted physical address after relocation. she gets updated, she's a phys_addr_t *, she's out here living her best pointer life 💅

🧚 DESCRIPTION 🧚

Returns 0 on success, negative errno otherwise.

that's it. that's the section. short king behavior fr fr — success is 0, failure is a negative errno, periodt 💜
