pcmcia_fixup_iowidth(9)

🦋 NAME 🦋

okay so this is the pcmcia_fixup_iowidth(9) page from the Kernel API Manual, bestie — and it's literally about one thing: reduce io width to 8bit. no cap. ✨

✨ SYNOPSIS ✨

here's the exact signature, don't come for me:

int pcmcia_fixup_iowidth (struct pcmcia_device *p_dev );

🎀 ARGUMENTS 🎀

• p_dev — pcmcia device. that's the whole cast, and honestly? iconic. 🫶

💅 DESCRIPTION 💅

pcmcia_fixup_iowidth is the function that allows a PCMCIA device driver to reduce the IO width to 8bit after having called pcmcia_enable_device previously. so yeah, it's giving post-enable width adjustment, and it's lowkey exactly the vibe it says on the tin. 💅✨

🌈 SEE ALSO 🌈

the kernel file to check is ./drivers/pcmcia/pcmcia_resource.c — and these are all the besties you should also see:

• release_io_space(9)
• alloc_io_space(9)
• pcmcia_map_mem_page(9)
