dpu_encoder...get_cwb_mask(9)
β¨ dpu_encoder_helper_get_cwb_mask β¨
okay bestie so you found yourself in the Kernel API Manual (section 9, the kernel-api girlies) and the page is literally called dpu_encoder...get_cwb_mask(9) β say that five times fast, i can't π«Ά. It's giving "one tiny helper function that does exactly one thing and we love her for it." Let's get into it π
πΈ NAME πΈ
dpu_encoder_helper_get_cwb_mask β the girl who gets the CWB blocks mask for the DPU encoder. that's it, that's the whole job, and she does it immaculately π
π¦ SYNOPSIS π¦
unsigned int dpu_encoder_helper_get_cwb_mask (struct dpu_encoder_phys
*phys_enc );
not me writing unsigned int in 2026... anyway she returns an unsigned int, no cap π
π ARGUMENTS π
phys_encβ pointer to the physical encoder structure β¨ that's literally it, one (1) argument, main character energy only
π SEE ALSO π
okay so this is the part where the manpage introduces you to the entire friend group. the whole squad lives in the kernel file ./drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c and honestly? iconic lineup. scroll at your own pace π§

β¨ source vibes come straight from ./drivers/gpu/drm/msm/disp/dpu1 and the date stamp says October 2026 β yes it's from the future, no we're not explaining that, bye bestie π¦ππ
