πŸ’– kvm_pgtable_...ree_unlinked(9) πŸ’–

okay bestie, welcome to the Kernel API Manual ✨ this one's about kvm_pgtable_stage2_free_unlinked, and honestly? it's giving "quiet cleanup crew, main character energy" πŸ§ΉπŸ’… no cap.


🌸 NAME 🌸

kvm_pgtable_stage2_free_unlinked β€” frees an unlinked stage-2 paging structure. literally just yeets it into the void 🫢


✨ SYNOPSIS ✨

void kvm_pgtable_stage2_free_unlinked (struct kvm_pgtable_mm_ops *mm_ops
, void *pgtable , s8 level );

that's the whole vibe check, bestie β€” void return, three args, no drama πŸ’œ


πŸŽ€ ARGUMENTS πŸŽ€

  • mm_ops β€” the memory management callbacks πŸ’« like, the little instruction manual for how memory gets handled around here
  • pgtable β€” the unlinked stage-2 paging structure that's getting freed πŸ¦‹ she's the one being sent off
  • level β€” the level of the stage-2 paging structure being freed πŸ“ an s8, so keep that in mind, k? iykyk

🌈 DESCRIPTION 🌈

so here's the tea β˜• the page-table is assumed to be unreachable by any hardware walkers prior to freeing β€” like, nobody's looking at her, she's off the grid, no hardware walker is gonna stroll up πŸ™ˆ and because of that assumption, no TLB invalidation is performed. none. zero. not a single flush πŸ”₯

⚠️ bestie, clock that word "assumed" β€” that's a precondition, not a vibe suggestion. if a hardware walker can still reach this page-table, that's on you, not on the function πŸ’€
