okay so literally welcome to the Kernel API Manual bestie, this page is about one tiny little helper that snitches when an interrupt ghosts you π«Ά
β¨ NAME β¨
dpu_encoder_helper_report_irq_timeout β the utility that reports the error when an irq has timed out, and likeβ¦ it also reports the frame error event to the crtc and does a debug dump. she does it all, no cap. π
π¦ SYNOPSIS π¦
void dpu_encoder_helper_report_irq_timeout (struct dpu_encoder_phys
*phys_enc , enum dpu_intr_idx intr_idx );
that's it. that's the whole vibe check. π
πΈ ARGUMENTS πΈ
phys_encβ pointer to the physical encoder structure. yes bestie, physical encoder. that's the one. β¨intr_idxβ the failing interrupt index. like, which interrupt flopped. this is how we know who to blame π
π SEE ALSO π
the kernel file lives at ./drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c β go read her, she's iconic. and then there's the whole friend group:

like, that's the whole group chat. every single one. periodt. π
and that's the page!! shoutout to the source over in ./drivers/gpu/drm/msm/disp/dpu1 π and it's dated October 2026 β so like, future vibes only. mwah, bye bestie π§π
