amdgpu_dm_c...ndle_crc_irq(9)

💅 amdgpu_dm_crtc_handle_crc_irq(9) — a whole Kernel API Manual moment

okay so bestie, gather round, because we're about to get into amdgpu_dm_crtc_handle_crc_irq 🎀 and yes the actual header up top had to abbreviate her name to amdgpu_dm_c...ndle_crc_irq(9) because apparently even man pages have a character limit and she is not about to be contained by it. iconic behavior honestly. ✨

🌸 NAME 🌸

amdgpu_dm_crtc_handle_crc_irq — the girl whose whole job is reporting the CRC on the given CRTC back to DRM. that's it, that's the mission, and she ate 💅

---

🦋 SYNOPSIS 🦋

void amdgpu_dm_crtc_handle_crc_irq (struct drm_crtc *crtc );

like literally that's it. one function, one argument, returns void because she's not here to give you anything back, she's here to report. periodt 🫶

---

⭐ ARGUMENTS ⭐

• crtc — the DRM CRTC object. that's your girl. she's the whole point of the call, no cap. 🎀

---

✨ DESCRIPTION ✨

okay so here's the vibe check 📋: this function should be called at the end of a vblank — like, exactly at the end, not mid-way, not whenever you feel like it — when the fb has been fully processed through the pipe. fully. processed. through. the. pipe. 🔥

think of it as the little "and that's a wrap!" moment at the end of the vblank, when everything's made it all the way through and it's time to report the CRC to DRM. main character energy for a tiny function ngl 💜

---

🌈 SEE ALSO 🌈

• the kernel file itself, and yes, she lives here: ./drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_crc.c 📁
• dm_need_dp_aux(9)
• dm_crc_source_should_start_dprx(9)
• dm_crc_source_should_stop_dprx(9)

go read them, iykyk 😭💖

real talk bestie: this is kernel-side stuff, so no funny business with when you call her — the description is the description. end of vblank, fb fully processed through the pipe. don't @ me. 🙈

and that's the page, babes 🧚 from ./drivers/gpu/drm/amd/display/..., dated October 2026, in all her amdgpu_dm_c...ndle_crc_irq(9) glory. slay, stay safe, and call your function at the right time 💀🍓
