STRUCT TEE_CMD_LOAD_TA(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– struct tee_cmd_load_ta (9) β€” like, the kernel API manual bestie πŸ’–

okay so real talk, this is the man page for struct tee_cmd_load_ta β€” it's the struct that loads a Trusted Application (TA) binary into the TEE. yes. that. sit with it, it's iconic. ✨


🌸 NAME 🌸

struct tee_cmd_load_ta β€” load Trusted Application (TA) binary into TEE</p> πŸŽ€

like, that's literally its whole job and it ate. no notes. πŸ’…


✨ SYNOPSIS ✨

struct tee_cmd_load_ta {
    u32 low_addr;
    u32 hi_addr;
    u32 size;
    u32 ta_handle;
    u32 return_origin;
 };

yes bestie, five u32s, that's the whole vibe. 🫢


πŸ¦‹ Members πŸ¦‹

okay so let's go through the squad one by one, no skipping, every single one matters:

  • low_addr β€” [in] bits [31:0] of the physical address of the TA binary. the low half, the little spoon, the bottom 32 bits. πŸ’œ
  • hi_addr β€” [in] bits [63:32] of the physical address of the TA binary. the high half! together with low_addr they make the full 64-bit physical address, and honestly that's teamwork. πŸ«‚
  • size β€” [in] size of TA binary in bytes. so like how big the TA actually is. byte count, periodt. πŸ“
  • ta_handle β€” [out] return handle of the loaded TA. this is the kernel handing you back a handle once the TA is loaded, so hold onto it, bestie, you'll need it. πŸ”₯
  • return_origin β€” [out] origin of return code after TEE processing. like, where did the return code come from?? this tells you. 🌈
heads up: three are [in] (you fill them in) and two are [out] (the kernel fills them in for you). don't mix them up or it's giving undefined chaos. 😭

and that's the whole page bestie, go load some TAs responsibly πŸ’– this little love letter lives in ./drivers/tee/amdtee, and it's dated October 2026 β€” so yeah, future vibes only. mwah πŸ’…βœ¨πŸŽ€
