vmw_resource_validate(9)

📦 version 7.3.1, in nixpkgs unstable

💅 vmw_resource_validate(9) — like, the whole kernel API manual vibe ✨

okay so bestie, welcome to the Kernel API Manual entry for vmw_resource_validate(9) — yes that "(9)" is the section, it's giving kernel-internals realness 🎀

🌸 NAME 🌸

vmw_resource_validate — makes a resource up-to-date and, like, actually visible to the device 💫

✨ SYNOPSIS ✨

int vmw_resource_validate (struct vmw_resource *res , bool intr , bool
dirtying );

that's the whole signature, no cap — copy it exactly, spacing and all, okurrr 🫶

🧚 ARGUMENTS 🧚

  • res — the resource we're making visible to the device. main character of the whole function ngl 👑
  • intr — do the waits interruptible if possible. like, let a signal cut in if it can 🙈
  • dirtying — a pending GPU operation is gonna dirty the resource. it's about to make a mess (affectionate) 💅

🔥 DESCRIPTION 🔥

so when this returns successfully, any backup DMA buffer that res->backup points to will be reserved and validated — both, periodt ✅

and if the hardware is running short on resources? she does not panic. she just repeatedly evicts resources of the same type until the validation succeeds. lowkey ruthless, highkey iconic 💀✨

🦋 RETURN 🦋

  • 0 (zero) — success, slay 🎉
  • -ERESTARTSYS — you got interrupted 😭
  • a negative error code — something failed, unfortunate fr fr 💔
