π intel_vgpu_pin_mm(9) π
okay bestie, so this page is from the Kernel API Manual and it's literally all about intel_vgpu_pin_mm β one tiny function that makes your vGPU memory object more... pinned. iykyk β¨
π NAME π
intel_vgpu_pin_mm β bumps up the pin count of a vGPU mm object. that's it, that's the whole vibe π
β¨ SYNOPSIS β¨
int intel_vgpu_pin_mm (struct intel_vgpu_mm *mm );
π¦ ARGUMENTS π¦
mmβ the target vgpu mm, aka the main character of this whole operation π
πΈ DESCRIPTION πΈ
so here's the tea: this function gets called when a user wants to actually use a vGPU mm object. simple, right?
but wait β there's a little plot twist π«Ά if this mm object hasn't been shadowed yet, then the shadow gets populated right at that moment. like, the shadow shows up fashionably late and we just deal with it. no cap, that's what happens.
β RETURN β
- Zero on success β slay, we love a win π
- a negative error code if it failed β aka the vibe check did not pass π

lowkey obsessed with how many of these there are. go read them all, bestie, you got this π§ββοΈ
and that's a wrap! π this masterpiece comes to you straight from ./drivers/gpu/drm/i915/gvt, dated October 2026 β so go forth, pin those mm objects, and stan intel_vgpu_pin_mm(9) forever πβ¨πππ
