pcmcia_disable_device(9)

✨ NAME ✨

okay so we're in the Kernel API Manual, and this page is pcmcia_disable_device(9) — the whole vibe is disable and clean up a PCMCIA device. periodt 💅

🌸 SYNOPSIS 🌸

void pcmcia_disable_device (struct pcmcia_device *p_dev );

🎀 ARGUMENTS 🎀

• p_dev — the associated PCMCIA device, bestie. that's the one we're talking about 🫶

🦋 DESCRIPTION 🦋

Here's the tea: pcmcia_disable_device is the driver-callable counterpart to pcmcia_enable_device. if a PCMCIA device is no longer used, drivers are expected to clean up and disable the device by calling this function. like, that's literally the assignment ✨

When this runs, any I/O ranges (iomem and ioports) will be released, the Vpp voltage will be set to 0, and IRQs will no longer be generated — at least if there is no other card function (of multifunction devices) being used. no cap, that's the whole cleanup situation 💖

bestie note: that IRQ part comes with the multifunction-device caveat, so don't forget it 😭
