💅 _base_check_for_trigger_pages_support — Kernel API Manual, section 9 ✨

okay so bestie, welcome to the Kernel API Manual, section 9, where we are literally checking the HBA firmware vibe. No cap, this page is short but the cross-reference list is a whole friend group 💖

🎀 NAME 🎀

_base_check_for_trigger_pages_support — checks whether HBA FW supports driver trigger pages or not. Slay. 💅

✨ SYNOPSIS ✨

int _base_check_for_trigger_pages_support (struct MPT3SAS_ADAPTER *ioc ,
u32 *trigger_flags );

🦋 ARGUMENTS 🦋

• ioc — per adapter object.
• trigger_flags — address where trigger page0's TriggerFlags value is copied.

🌸 RETURN 🌸

Returns the trigger flags mask if HBA FW supports driver trigger pages. Otherwise it returns -EFAULT if driver trigger pages are not supported by FW, or returns EAGAIN if diag reset occurred due to FW fault and asking the caller to retry the command. That's the whole deal, bestie 🫶

🔥 SEE ALSO 🔥

Kernel file: ./drivers/scsi/mpt3sas/mpt3sas_base.c — yes, that's where the source lives 🌈

okay that's the whole page, bestie — source/version footer says ./drivers/scsi/mpt3sas, date says October 2026, page is _base_check...ages_support(9). byeee, mwah 🫶💖✨
