📦 version 7.3.1, in nixpkgs unstable

💅 vmw_dx_shader_cotable_list_scrub — the kernely manual page, bestie edition

okay so this is section 9 of the Kernel API Manual, and the header got its little name squished to vmw_dx_shade...e_list_scrub(9) but we all know who she is 💖 the full name is right there in a sec, don't worry.

✨ NAME ✨

vmw_dx_shader_cotable_list_scrub — the unbind_func callback for DX shaders, no cap 🎀

Like, that's literally her job title. She's the callback. She scrubs. She's booked and busy.

🌸 SYNOPSIS 🌸

void vmw_dx_shader_cotable_list_scrub (struct vmw_private *dev_priv ,
struct list_head *list , bool readback );

That's the whole signature, take it in 🫶 note she returns void — she does the work and she does not report back, main character energy honestly.

🦋 ARGUMENTS 🦋

  • dev_priv — pointer to the device private structure. your classic dev_priv situation, iykyk 💜
  • list — the list of cotable resources. yes THE list. the one with the cotable resources on it. 🌈
  • readback — a bool that tells you whether the call was part of a readback unbind. like, was this a readback unbind or not, that's the vibe check ✨

🧚 DESCRIPTION 🧚

So what does she actually do? She scrubs all the shader MOBs 🔥

And why, you ask? Because after she's done, any subsequent shader unbind or shader destroy operation won't need to swap in the context 😭 that's the whole point, that's the flex, she's saving you a context swap.

literally just scrubbing MOBs so future shader unbinds and destroys don't have to swap in the context. that's the tea. ☕

like, the entire shader cinematic universe 🌟 go read them, I'll wait 💅

okay and that's the page!! this little icon came out of ./drivers/gpu/drm/vmwgfx, dated October 2026, and she's filed under the Kernel API Manual 🎀 slay, go scrub some MOBs, ily, bye 💖✨
