xe_tlb_inval_fence_init(9)
π 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 π«Ά
β¨ NAME β¨
xe_tlb_inval_fence_init β the one where we initialize a TLB invalidation fence π
πΈ SYNOPSIS πΈ
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 β¨
π ARGUMENTS π
tlb_invalβ the TLB invalidation client, aka the main character of this operation πfenceβ the TLB invalidation fence we're initializing. this is the one getting set up, she's the moment πstackβ aboolthat says whether the fence is a stack variable. yep, that's it, that's the whole vibe check π¦
π DESCRIPTION π
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 π₯
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 π
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 π 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-finiβ¦ it's giving "trust the process" energy π
