mpt3sas_conf...e_device_pg2(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… mpt3sas_config_get_pcie_device_pg2 β€” obtain pcie device page 2 ✨

okay bestie, so this is a page from the Kernel API Manual, and the page is literally called mpt3sas_conf...e_device_pg2(9) (yes the title is truncated, no that's not my fault, the man page did that 😭). Anyway. Sit down, grab a strawberry πŸ“, we're getting a PCIe device page 2 out of the firmware and it's gonna slay.


🌸 SYNOPSIS 🌸

int mpt3sas_config_get_pcie_device_pg2 (struct MPT3SAS_ADAPTER *ioc ,
Mpi2ConfigReply_t *mpi_reply , Mpi26PCIeDevicePage2_t *config_page , u32
form , u32 handle );

look at that signature. iconic. five arguments, one int coming back, zero notes. πŸ’…


πŸŽ€ ARGUMENTS πŸŽ€

  • ioc β€” the per adapter object. it's giving "this is the HBA we're talking about" energy πŸ‘‘
  • mpi_reply β€” the reply MF payload that the firmware hands back to you. yes mf. that's what the man page says, we don't ask questions 🫢
  • config_page β€” the contents of the config page. this is where the goods land πŸ“₯
  • form β€” GET_NEXT_HANDLE or HANDLE. like, pick your vibe: iterate to the next handle, or use the handle you already have πŸ’«
  • handle β€” the device handle. the actual thing you're asking about πŸ¦‹

πŸ’€ CONTEXT πŸ’€

sleep.

that's it. that's the whole context section. she sleeps 😴 β€” meaning this call can sleep, so don't you dare call it from somewhere that can't. that's not me being dramatic, that's just true.


⭐ RETURN ⭐

0 for success, non-zero for failure. that's the whole deal, no cap. if you get 0 you ate πŸ”₯, if you get non-zero, well... it's giving "check your handle, bestie" πŸ™ˆ


🌈 SEE ALSO 🌈

okay this is the long one, hydrate first πŸ’§ β€” all of these live in the kernel file ./drivers/scsi/mpt3sas/mpt3sas_config.c:

like I said. a whole friend group πŸ’–


real talk: sleep. in CONTEXT is the one thing here that will actually bite you if you ignore it. process context only, bestie. 🧚

and that's the page!! πŸ’œ it lives under ./drivers/scsi/mpt3sas, dated October 2026, from the Kernel API Manual β€” mwah, go get your page 2, iykyk πŸŽ€βœ¨πŸ¦‹
