🎀 __pata_platform_probe — attach a platform interface 🎀

okay so this is the manual page for __pata_platform_probe(9) from the Kernel API Manual, and it's literally about attaching a platform interface. bestie, it's giving "low-level glue code but make it iconic" 💅

✨ NAME ✨

__pata_platform_probe — attach a platform interface

---

💖 SYNOPSIS 💖

int __pata_platform_probe (struct device *dev , struct resource *io_res
       , struct resource *ctl_res , struct resource *irq_res , unsigned int
       ioport_shift , int __pio_mask , const struct scsi_host_template *sht ,
       bool use16bit );

🫶 ARGUMENTS 🫶

• dev — the device 🫶
• io_res — Resource representing I/O base ✨
• ctl_res — Resource representing CTL base 🎀
• irq_res — Resource representing IRQ and its flags 🔥
• ioport_shift — I/O port shift 💅
• __pio_mask — PIO mask 🌸
• sht — scsi_host_template to use when registering 🦋
• use16bit — Flag to indicate 16-bit IO instead of 32-bit ⭐

🌈 DESCRIPTION 🌈

So basically: this registers a platform bus IDE interface. Such interfaces are PIO, and we assume they do not support IRQ sharing. no cap, that's the vibe 🔥

Platform devices are expected to contain at least 2 resources per port:

• I/O Base (IORESOURCE_IO or IORESOURCE_MEM) 💖
• CTL Base (IORESOURCE_IO or IORESOURCE_MEM) ✨

and optionally:

• IRQ (IORESOURCE_IRQ) ⚡

If the base resources are both mem types, the ioremap is handled here. For IORESOURCE_IO, it's assumed that there's no remapping necessary. And if no IRQ resource is present, PIO polling mode is used instead. periodt 💅
