hinic_hwdev_msix_set(9)

💅 hinic_hwdev_msix_set(9) — from the Kernel API Manual, bestie

okay so real talk, this is a kernel API page for hinic_hwdev_msix_set, straight out of the Kernel API Manual (section 9, the fun one), and it's basically the function that ✨dresses up✨ an MSI-X entry with all its message attributes. tiny function, seven args, zero chill. let's get into it 🌸

---

✨ NAME ✨

hinic_hwdev_msix_set — set message attribute for msix entry 💅

no cap, that's the whole gig: you're setting the message attributes for one msix entry. iconic behavior.

---

🎀 SYNOPSIS 🎀

int hinic_hwdev_msix_set (struct hinic_hwdev *hwdev , u16 msix_index ,
u8 pending_limit , u8 coalesc_timer , u8 lli_timer_cfg , u8
lli_credit_limit , u8 resend_timer );

like, look at all those u8s. it's giving "someone was very committed to not wasting bytes" and honestly? respect 🫶

🦋 ARGUMENTS 🦋

• hwdev — the NIC HW device 🖥️ like, the actual hardware baddie you're configuring. main character energy.
• msix_index — msix_index 💀 yes bestie, the description is literally just the name again. some docs are like that. it's the index. we move on.
• pending_limit — the maximum pending interrupt events, and the unit is 8 ⚡ so think in chunks of 8, not ones.
• coalesc_timer — coalesc period for the interrupt, unit is 8 us ⏱️ i.e. 8 microseconds per unit, don't @ me.
• lli_timer_cfg — replenishing period for low latency credit, unit is 8 us 🌈 (the "lli" is the low latency situation, iykyk)
• lli_credit_limit — maximum credits for low latency msix messages, unit is 8 💜 credits! for the low latency msix messages! in units of 8!
• resend_timer — maximum wait for resending msix, and its unit is the coalesc period 👑 so it's measured in coalesc_timers, not seconds. cute little relative timer.

fr fr, watch the units on these — most of them are "unit 8", a couple are "unit 8 us", and the last one is measured in coalesc periods. mixing those up is a whole vibe check you do not want to fail 🙈

💖 DESCRIPTION 💖

Return 0 - Success, negative - Failure 🎯

that's it. that's the description. zero and below, king. if it comes back negative, something went sideways and you should look at it with concern 😭

okay that's the whole page!! source/version tag is ./drivers/net/ethernet/huawei/... and it's dated October 2026 🗓️ so like, future-coded manual, and the whole thing signs off as hinic_hwdev_msix_set(9). go set some msix attributes, bestie, you got this 💅✨🫶
