drm_atomic_...t_writebacks(9)
okay so bestie, youβre on the drm_atomic_...t_writebacks(9) page from the Kernel API Manual, and itβs literally about issuing writebacks π no cap, letβs get into it.
β¨ NAME β¨
drm_atomic_helper_commit_writebacks - issue writebacks
π SYNOPSIS π
void drm_atomic_helper_commit_writebacks (struct drm_device *dev ,
struct drm_atomic_commit *state );
π«Ά ARGUMENTS π«Ά
devβ the DRM device, like the whole graphics vibes container π«Άstateβ the atomic state object being committed, periodt π
π DESCRIPTION π
Okay so hereβs the tea: this function loops over the connectors, checks if the new state requires a writeback job to be issued, and in that case it issues an atomic commit on each connector. Thatβs the whole vibe β connector by connector, doing the writeback thing when the new state says itβs needed β¨
