qed_dbg_pro...ump_buf_size(9)

📦 version 7.3.1, in nixpkgs unstable

👑 qed_dbg_protection_override_get_dump_buf_size — a kernel API manual moment 💅

okay so bestie, we're in the Kernel API Manual today (the page header literally says qed_dbg_pro...ump_buf_size(9), yes it's truncated, no we're not gonna fight about it) and the vibes are extremely driver-internals. Buckle up 🎀

✨ NAME ✨

qed_dbg_protection_override_get_dump_buf_size — literally just tells you how big a buffer you need for the protection override window results. that's it. that's the whole job. no cap 💖

🦋 SYNOPSIS 🦋

enum dbg_status qed_dbg_protection_override_get_dump_buf_size (struct
qed_hwfn *p_hwfn , struct qed_ptt *p_ptt , u32 *buf_size );

three args, returns a enum dbg_status, iconic behavior honestly 🌸

🎀 ARGUMENTS 🎀

  • p_hwfn — your HW device data. the main character of this whole situation 🫶
  • p_ptt — the Ptt window used for writing the registers. that's its whole thing, it writes registers, slay ✨
  • buf_size — (OUT) the required buffer size, and bestie it's measured in dwords 💅 this is where the answer goes, so don't forget to actually pass a pointer, i'm begging 😭

💀 RETURN 💀

it returns an error if the following holds:

  • The version wasn't set

Otherwise? returns ok. that's the whole flowchart, lowkey refreshing 🌈

fr fr, that's the entire error condition — version not set = error, version set = ok. no hidden lore, no extra clauses 🍓
