dc_dmub_srv_release_hw(9)

✨ dc_dmub_srv_release_hw(9) ✨

okay bestie so this is a Kernel API Manual page, section 9 — yes we're in the big-kid kernel-functions section, main character energy only 💅

---

🌸 NAME 🌸

dc_dmub_srv_release_hw — she literally just tells the DMUB service that HW access is no longer required. that's it. that's the whole job. queen of closure 🎀

---

🦋 SYNOPSIS 🦋

void dc_dmub_srv_release_hw (const struct dc *dc );

note the void — she gives nothing back, no return value, zero notes. iconic behavior tbh. and dc is const, so nobody's out here mutating it. we love boundaries ✨

---

💖 ARGUMENTS 💖

• dc — so the manpage literally says -- undescribed -- 😭 which, okay, mysterious. but the DESCRIPTION has your back and tells you it's a pointer to the DC object. so like, yeah. a pointer. to the DC object. we got there together 🫶

---

🔥 DESCRIPTION 🔥

okay so real talk: dc is a pointer to the DC object. that's the whole description. she's a one-liner, she's efficient, she doesn't over-explain herself.

and the vibe of the function itself, per the NAME section: it notifies the DMUB service that HW access is no longer required. so like, you had the hardware, you did your thing, and now you're releasing it. closure. boundaries. slay 🙈

like look at that whole friend group 💀 cursor offload girlies, CRC girlies, HDCP interrupt girlies — everyone's here. iykyk 🌈

💀 tiny heads up: the argument and the description are both in here, and they kind of say the same thing. that's not me being redundant, that's the original page being its authentic self. no cap.

and that's the whole page, bestie!! 🍓 comes to you straight from ./drivers/gpu/drm/amd/display/dc and dated October 2026 — yes, the future, we're ahead of schedule ✨ go release that hardware access, you absolute legend 👑💜
