vmw_execbuf...se_pinned_bo(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the vmw_execbuf...se_pinned_bo(9) page in the Kernel API Manual — yes, the title is giving truncated main-character energy, but the actual function is vmw_execbuf_release_pinned_bo, and she's here to flush queries and unpin the pinned query bo. pull up a chair 🎀✨

🌸 NAME 🌸

vmw_execbuf_release_pinned_bo — flush queries and unpin the pinned query bo. literally the whole point, no cap 💅

✨ SYNOPSIS ✨

void vmw_execbuf_release_pinned_bo (struct vmw_private *dev_priv );

🫶 ARGUMENTS 🫶

  • dev_priv — the device private structure. that's the one, bestie 🦋

💖 DESCRIPTION 💖

okay so here's the vibe: this function should be used to unpin the pinned query bo, or as a query barrier when we need to make sure that all queries have finished before the next fifo command. (for example, on hardware context destructions, where the hardware may otherwise leak unfinished queries — yes, that kind of mess 😭💀).

it does not return any failure codes, but it makes attempts to do safe unpinning in case of errors. so no return-value drama, just bestie-effort safe unpinning when stuff goes sideways 🫶.

also, the function will synchronize on the previous query barrier, and will thus not finish until that barrier has executed. so if you're waiting on it, you're lowkey waiting on that barrier too — periodt ⭐.
