amdgpu_info_ioctl(9)

💖 NAME 💖

okay bestie, welcome to the amdgpu_info_ioctl(9) page from the Kernel API Manual. the name is literally the assignment: amdgpu_info_ioctl - answer a device specific request.

✨ SYNOPSIS ✨

the signature is serving:

int amdgpu_info_ioctl (struct drm_device *dev , void *data , struct
       drm_file *filp );

🫶 ARGUMENTS 🫶

• dev — drm device pointer. the DRM device pointer bestie in question.
• data — request object. the request object carrying the ask.
• filp — drm filp. the DRM file pointer, periodt.

💅 DESCRIPTION 💅

so this function is used to pass device specific parameters to the userspace drivers. it's the kernel-to-userspace info drop, no cap. examples include: pci device id, pipeline parms, tiling params, etc. (all asics). yes, all asics — every single one.

returns 0 on success, -EINVAL on failure. that's the whole vibe check: 0 slays, -EINVAL is the flop era.
