lpfc_aer_support_store(9)
π lpfc_aer_support_store β a Kernel API Manual moment (yes, it's from the Kernel API Manual, bestie, we're fancy now)
okay so picture this: you're deep in the kernel docs, the vibes are immaculate, and you find this little function. Here's literally everything about it. No gatekeeping. π«Ά
β¨ NAME β¨
lpfc_aer_support_store β set the adapter for aer support πΈ
π¦ SYNOPSIS π¦
ssize_t lpfc_aer_support_store (struct device *dev , struct
device_attribute *attr , const char *buf , size_t count );
π ARGUMENTS π
devβ the class device, which gets converted into a Scsi_host. it's giving β¨glow upβ¨attrβ device attribute. not used. she's just there for the vibes πbufβ the string containing the enable or disable aer flag.countβ unused variable. iconic of her honestly π
π DESCRIPTION π
so here's the tea: PCIe error reporting is already enabled by the PCI core, so drivers literally don't need to do anything. like, nothing. zero. zilch.
the interface is kept around purely for backwards compatibility β but it does nothing. no cap. it's a little ghost of a function, still showing up to the group chat, contributing zero messages. π
do not expect this thing to actually toggle anything, bestie. it is a decorative little interface and that's the whole point.
π RETURN π
- on success, it returns the length of
bufπ - it returns
-EINVALifvalis out of range π

okay that's the whole page, you read it all, you're basically a kernel dev now, i'm obsessed with you π§ββοΈ
mwah π β this cutie lives in ./drivers/scsi/lpfc, and the manual is dated October 2026. go forth and do literally nothing with this function, exactly as intended. periodt. π
