pt_table_pa(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… pt_table_pa β€” the manual page, but make it make sense

okay so bestie, welcome to pt_table_pa(9) from the Kernel API Manual ✨ this one's short and sweet and honestly kinda iconic in its simplicity β€” it's the little function that hands you back a physical address and refuses to elaborate πŸ’–


🌸 NAME 🌸

pt_table_pa β€” return the CPU physical address of the table entry</p> πŸŽ€


✨ SYNOPSIS ✨

pt_oaddr_t pt_table_pa (const struct pt_state *pts );

that's it. one arg. no drama. we love a low-maintenance signature 🫢


πŸ¦‹ ARGUMENTS πŸ¦‹

  • pts β€” the entry you're querying, bestie. that's the whole vibe check 🌈

πŸ’… DESCRIPTION πŸ’…

okay so here's the tea β˜• β€” this function is only ever called on PT_ENTRY_TABLE entries. like, that's its whole lane. don't be sending it anything else, it's not that girl πŸ™ˆ

and the rule? must return the same value passed to pt_install_table. no cap. no cap at ALL. it's literally giving "what goes in comes back out" energy πŸ‘‘

bestie please note the must β€” this isn't a suggestion, it's a contract, and the table entry is holding you to it πŸ’€

πŸ”₯ SEE ALSO πŸ”₯

the whole friend group showed up for this one, so let's give them all their flowers πŸ’ (kernel file: ./drivers/iommu/generic_pt/pt_common.h β€” that's the group chat, iykyk)

like, all of them. the entire roster. squad goals fr fr 🌟


and that's the page, bestie!! πŸŽ€ this lil section of the manual lives at ./drivers/iommu/generic_pt and it's dated October 2026 β€” so if you're reading this from the future, hiii, hope the kernel's slaying πŸ’œπŸ¦‹βœ¨
