STRUCT TGT_DEV_PCIE(9)

💖 struct tgt_dev_pcie(9) 💖

okay so bestie, welcome to the struct tgt_dev_pcie(9) page from the Kernel API Manual — and before you ask, yes, this is the whole thing, and yes, it's absolutely iconic that a struct this small has a whole manual page about it. Periodt. ✨

This one's all about a PCIe device's very own little info stash — the device-specific information cached from firmware given data. It's giving "firmware told me stuff, I wrote it down so I wouldn't forget." 🎀

🌸 SYNOPSIS 🌸

like, here's the whole shape of her, exactly as she is, no edits:

struct tgt_dev_pcie {
    u32 mdts;
    u16 capb;
    u8 pgsz;
    u8 abort_to;
    u8 reset_to;
    u16 dev_info;
 };

look at that indentation on the closing brace — I didn't touch it, that's just her vibe. 💅

✨ Members ✨

okay so this is the fun part, let's meet the squad one by one 🫶

• mdts — Maximum data transfer size. huge u32 energy, literally the biggest field in here, main character energy for sure 👑
• capb — Device capabilities. a u16 of pure "here's what I can do" ✨
• pgsz — Device page size. u8, tiny but she knows her page size, iykyk 🦋
• abort_to — Timeout for abort TM. ⏰ don't sleep on this one, it's the abort TM timeout, lowkey important
• reset_to — Timeout for Target/LUN reset TM. 🔥 also a timeout, but for Target/LUN reset TM, different thing, keep 'em straight bestie
• dev_info — Device information bits. u16 of bits! bits! which bits? device information bits, that's the whole tea 🍓

heads up: every single one of these descriptions is exactly as much as the manpage gives you. no cap, I'm not gonna invent extra meaning for you, because that would be a vibe crime. 💀

💜 SEE ALSO 💜

okay so this is the part where the manpage name-drops literally everyone in the friend group. brace yourself, they're all in the kernel file ./drivers/scsi/mpi3mr/mpi3mr.h, and here's the full roll call, no one left behind:

• struct mpi3mr_nvme_pt_sge(9)
• struct mpi3mr_buf_map(9)
• struct mpi3mr_compimg_ver(9)
• struct segments(9)
• struct op_req_qinfo(9)
• struct op_reply_qinfo(9)
• struct mpi3mr_intr_info(9)
• struct mpi3mr_throttle_group_info(9)
• struct mpi3mr_hba_port(9)
• struct mpi3mr_sas_port(9)

• union _form_spec_inf(9)
• struct mpi3mr_tgt_dev(9)
• mpi3mr_tgtdev_get(9)
• mpi3mr_free_tgtdev(9)

like… that's a whole group chat right there, and every one of them is in ./drivers/scsi/mpi3mr. slay 💅

🧚 cute sign-off 🧚

and that's the page bestie!! this little angel lives in the kernel source tree at ./drivers/scsi/mpi3mr, the doc's dated October 2026, and the footer credits it right back to struct tgt_dev_pcie(9). go forth and cache your firmware data responsibly, ily, bye 💖🌈⭐
