pvr_fw_object_fw_unmap(9)

📦 version 7.3.1, in nixpkgs unstable

✨ pvr_fw_object_fw_unmap ✨

okay bestie, so like — this is a kernel API manual page, specifically from the pvr_fw_object_fw_unmap(9) family of things 💖 yes, the (9) means it's a kernel-space function, we love a section-9 moment 🎀

🌸 NAME 🌸

pvr_fw_object_fw_unmap — unmap a FW object that was, like, previously mapped 👋 no cap, that's the whole vibe check

🦋 SYNOPSIS 🦋

int pvr_fw_object_fw_unmap (struct pvr_fw_object *fw_obj );

literally just one argument. she's lowkey low-maintenance 💅

💜 ARGUMENTS 💜

  • fw_obj — the FW object you're trying to unmap. that's it. that's the whole parameter. give her the pointer and she'll handle the rest 🫶

⭐ RETURN ⭐

here's what you might get back, bestie — pay attention:

  • 0 on success 🎉 (the slay outcome, we're obsessed)
  • -EINVAL if the object is not currently mapped 💀 like, there's nothing to unmap, so she's gonna be like "girl, what?"

🔥 SEE ALSO 🔥

okay this is the part where I tell you where to go next, and honestly the cross-reference list is long — she's connected, iykyk 👑

Kernel file ./drivers/gpu/drm/imagination/pvr_fw.c plus all these iconique friends:

fr fr, pvr_fw_object_fw_map(9) is the natural counterpart here — you map, you unmap, the circle of life 🌈

so yeah — that's the whole page, bestie. short, sweet, and to the point. unmap responsibly, check your return code, and remember: -EINVAL means the object wasn't mapped in the first place, so maybe go touch some grass instead of debugging that 💅✨

huge shoutout to the source/version line at the bottom: ./drivers/gpu/drm/imagination, dated October 2026, and the manual is pvr_fw_object_fw_unmap(9) — ily, mwah 🫶💖
