lpfc_sli_enable_intr(9)

✨ NAME ✨

okay bestie, welcome to lpfc_sli_enable_intr(9) from the Kernel API Manual — the function that enables device interrupt to SLI-3 device. periodt 💅

🦋 SYNOPSIS 🦋

uint32_t lpfc_sli_enable_intr (struct lpfc_hba *phba , uint32_t cfg_mode
);

🎀 ARGUMENTS 🎀

• phba — pointer to lpfc hba data structure.
• cfg_mode — Interrupt configuration mode (INTx, MSI or MSI-X).

🌈 DESCRIPTION 🌈

okay so this routine is invoked to enable device interrupt and associate the driver's interrupt handler(s) to interrupt vector(s) to device with SLI-3 interface spec. it's giving interrupt-enable realness 💖

Depending on the interrupt mode configured to the driver, the driver will try to fallback from the configured interrupt mode to an interrupt mode which is supported by the platform, kernel, and device in the order of: MSI-X -> MSI -> IRQ. the fallback chain ate, no cap ✨

Return codes: 0 - successful other values - error 💀
