xe_tlb_inval_fence_init(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… xe_tlb_inval_fence_init(9) β€” from the Kernel API Manual, bestie!

okay so picture this: it's a whole kernel API manual page, the title is xe_tlb_inval_fence_init(9), and it's literally about getting a TLB invalidation fence ready to go. no cap, we're doing this together 🫢


✨ NAME ✨

xe_tlb_inval_fence_init β€” the one where we initialize a TLB invalidation fence πŸ’–


🌸 SYNOPSIS 🌸

void xe_tlb_inval_fence_init (struct xe_tlb_inval *tlb_inval , struct
       xe_tlb_inval_fence *fence , bool stack );

like, that's the whole call. three args, one void, zero drama ✨


πŸŽ€ ARGUMENTS πŸŽ€

  • tlb_inval β€” the TLB invalidation client, aka the main character of this operation πŸ‘‘
  • fence β€” the TLB invalidation fence we're initializing. this is the one getting set up, she's the moment πŸ’…
  • stack β€” a bool that says whether the fence is a stack variable. yep, that's it, that's the whole vibe check πŸ¦‹

πŸ’œ DESCRIPTION πŸ’œ

so here's the tea: you call this to initialize a TLB invalidation fence so it's actually usable. that's the whole point, that's the assignment, and she ate πŸ”₯

and listen, this part matters β€” xe_tlb_inval_fence_fini will be automatically called when the fence is signalled. automatically. you don't have to do it, it just happens, no cap πŸ™ˆ

and bestie, all fences must signal β€” like, every single one, that's not optional. and the fini still gets called automatically even on error 😭 so don't stress about cleanup on the error path, the kernel's got you fr fr.

the way that this whole thing is just init + guaranteed auto-fini… it's giving "trust the process" energy 🌈
