amdgpu_dm_p...feature_mask(9)

✨ NAME ✨

okay so bestie, this is amdgpu_dm_psr_set_dc_feature_mask — it's literally the function that sets the DC feature mask for KUnit tests 💅 (yes, the manual name has it squished up as amdgpu_dm_p...feature_mask(9) in the header, that's just the page title being shy, we move)

🌸 SYNOPSIS 🌸

void amdgpu_dm_psr_set_dc_feature_mask (unsigned int feature_mask );

that's it. that's the whole vibe. one void return, one argument, zero drama 🎀

💖 ARGUMENTS 💖

• feature_mask — the DC feature mask you're setting while you're testing out amdgpu_dm_psr_fill_caps. it's an unsigned int, and it's giving "test harness main character energy" fr fr 🔥
