💖 t7xx_pcie_set_mac_msix_cfg — Kernel API Manual, section 9 💖

okay bestie, so this is a little function from the Kernel API Manual (section 9, yes the fun one) and it's genuinely so simple you're gonna slay it. Let's go 🫶

✨ NAME ✨

t7xx_pcie_set_mac_msix_cfg — the girlie that writes the MSIX control configuration. literally that's her whole job 💅

✨ SYNOPSIS ✨

void t7xx_pcie_set_mac_msix_cfg (struct t7xx_pci_dev *t7xx_dev ,
       unsigned int irq_count );

✨ ARGUMENTS ✨

• t7xx_dev — the MTK device. your main character struct 🌸
• irq_count — the number of MSIX IRQ vectors. like, how many of them there are 🔥

✨ DESCRIPTION ✨

Write IRQ count to device. That's it, that's the whole vibe — no cap, it just takes the count and writes it on over to the device. iconic behaviour honestly ✨

heads up bestie: it returns void, so there's nothing to check afterwards. no exit status, no errno, nothing. it just does the thing 💀
