From 70a101f8639a712576c3ca1d910564c7e2ec91d8 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Wed, 8 Apr 2015 18:56:53 -0700 Subject: [PATCH] drm/i915: Switch to full atomic helpers for plane updates/disable, take two Switch from our plane update/disable entrypoints to use the full atomic helpers (which generate a top-level atomic transaction) rather than the transitional helpers (which only create/manipulate orphaned plane states independent of a top-level transaction). Various upcoming work (SKL scalers, atomic watermarks, etc.) requires a full atomic transaction to behave properly/cleanly. Last time we tried this, we had to back out the change because we still call the drm_plane vfuncs directly from within our legacy modesetting code. This potentially results in nested atomic transactions, locking collisions, and other failures. To avoid that problem again, we sidestep the issue by calling the transitional helpers directly (rather than through a vfunc) when we're nested inside of other legacy modesetting code. However this does allow legacy SetPlane() ioctl's to process an entire drm_atomic_state transaction, which is important for upcoming patches.
