pmcraid_init_instance(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

🌸 pmcraid_init_instance(9) β€” from the Kernel API Manual 🌸

okay so bestie, welcome to the glow-up era of pmcraid_init_instance(9) πŸ’… this is the page where we set up the per-instance data structure, and honestly it's giving "quiet but essential" main character energy. let's get into it πŸ’–


✨ NAME ✨

pmcraid_init_instance β€” literally the function that sets up the per-instance data structure 🫢 like it initializes the per instance data structure, that's the whole vibe, no cap


πŸ¦‹ SYNOPSIS πŸ¦‹

int pmcraid_init_instance (struct pci_dev *pdev , struct Scsi_Host *host
, void __iomem *mapped_pci_addr );

yes the formatting is a little chaotic, we don't gatekeep, we copy it exactly πŸ’€


πŸŽ€ ARGUMENTS πŸŽ€

  • pdev β€” a pointer to the pci_dev structure, i.e. the pci device structure itself. she's holding the device info, iconic πŸ‘‘
  • host β€” a pointer to the Scsi_Host structure. this is your Scsi_Host structure pointer, she's important ✨
  • mapped_pci_addr β€” the memory mapped IOA configuration registers πŸ”₯ that's literally what it is: memory mapped IOA config registers

πŸ’œ DESCRIPTION πŸ’œ

so what actually happens? the return value is 0 on success, and non-zero in case of any failure 😭 that's the whole deal β€” 0 means slay, anything else means something went sideways. periodt.

bestie pls note: non-zero = failure, do not skim past that one πŸ™ˆ

🌈 SEE ALSO 🌈

first up, the kernel file itself, no skips: ./drivers/scsi/pmcraid.c β€” that's literally the kernel file, iykyk πŸ“

and now, the full friend group, in order, every single one of them (yes all of them, we don't leave anyone on read) 🫢


and that's the page bestie, go forth and initialize responsibly πŸ§šπŸ’«

sign-off time: this whole thing lives under ./drivers/scsi, dated October 2026 β€” mwah, take care of her, she's iconic πŸ’‹πŸŒΈ
