✨ quickspi_alloc_report_buf(9) ✨

okay so bestie, welcome to the Kernel API Manual — this is the quickspi_alloc_report_buf page and it's lowkey iconic. it's giving "tiny function, very important job" energy, and we're gonna go through it together, k? 🫶

🌸 NAME 🌸

quickspi_alloc_report_buf — alloc report buffers 💅 (yes, plural, she does three of them, main character behavior fr fr)

---

🎀 SYNOPSIS 🎀

int quickspi_alloc_report_buf (struct quickspi_device *qsdev );

like, one argument, one int back. clean. minimal. obsessed. ✨

---

🦋 ARGUMENTS 🦋

• qsdev — pointer to the quickspi device structure. that's it, that's the whole input. she just needs to know which device she's setting up for 🧚

---

💖 DESCRIPTION 💖

okay so the way this works is, she allocates three separate buffers and each one has its own little job. no cap, all three matter:

• the report descriptor buffer — this one gets allocated and it'll be used for restore TIC HID report descriptor. that's her whole purpose in life 🎀
• the input report buffer — allocated, and it'll be used for receive HID input report data from TIC. data comes in, bestie 💅
• the output report buffer — allocated, and it'll be used for store HID output report, such as set feature. data goes out, and yeah, set feature is literally the example given 🌸

so yeah, three allocations, three vibes, all handled in one call. slay. 👑

---

⭐ RETURN ⭐

• 0 — if successful 🥳
• error code — on failed 😭 (yes, she returns the error code, she's not gonna leave you guessing)

💀 friendly reminder that this is undocumented dark-magic-adjacent kernel territory — the page says what it says and nothing more, so don't come for me with "but what if—" 🫶

okay that's the whole page, you ate that 💜 — this came to you from ./drivers/hid/intel-thc-hid/in..., dated October 2026, and yes the real title is still quickspi_alloc_report_buf(9) in case you forgot already 😭 bye bestie! 🍓
