amdgpu_proc_options_ioctl(9)

💅 NAME 💅

amdgpu_proc_options_ioctl — set per-fd user options. Bestie, that's literally the whole vibe: this is the ioctl that sets per-fd user options, and it came from the Kernel API Manual ✨

🦋 SYNOPSIS 🦋

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

🎀 ARGUMENTS 🎀

• dev — drm dev pointer, the main-character drm_device in question 🫶
• data — pointer to struct drm_amdgpu_proc_options — that's where the options info lives ✨
• filp — drm file, aka the drm_file bestie in this story 💖

🌸 DESCRIPTION 🌸

Okay so this function sets options stored on the per-file amdgpu_fpriv. That's the assignment, and it ate 💅

Currently the only supported option is AMDGPU_PROC_OPTIONS_OP_KFD_SIGBUS_DELAY, and no cap, it controls how KFD delivers SIGBUS for poison/RAS events to the calling process — immediate, suppressed, or delayed by N milliseconds. Periodt. 🔥
