💅 drm_core_check_feature(9) 💅

hiii bestie!! welcome to the Kernel API Manual ✨ we're doing a little feature-flag vibe check today, and honestly it's giving very "quick yes/no but make it kernel" energy. no cap.

🎀 NAME 🎀

drm_core_check_feature — check driver feature flags

✨ SYNOPSIS ✨

       bool drm_core_check_feature (const struct drm_device *dev , enum
       drm_driver_feature feature );

🫶 ARGUMENTS 🫶

• dev — the DRM device to check, aka which device we're looking at 💖
• feature — the feature flag, aka the thing we're checking for ✨

💖 DESCRIPTION 💖

okay so this checks dev for driver features. for the full lore, see drm_driver.driver_features, drm_device.driver_features, and the various enum drm_driver_feature flags. iykyk 💅

it returns true if the feature is supported, and false otherwise. literally that's the whole vibe check, and it ate — slay 💀✨
