The culprit was the generic deferred_io code (qxl driver switched to it since 4.7). There is a race between the dirty clip update and the call of callback. In drm_fb_helper_dirty(), the dirty clip is updated in the spinlock, while it kicks off the update worker outside the spinlock. Meanwhile the update worker clears the dirty clip in the spinlock, too. Thus, when drm_fb_helper_dirty() is called concurrently, schedule_work() is called after the clip is cleared in the first worker call. This patch addresses it by validating the clip before calling the dirty fb callback.

Same holds for drivers that don't support zpos at all (i915 actually falls into this category right now since we've not yet added zpos support). Allow drivers more freedom by letting them deal with zpos themselves instead of doing it in drm_atomic_helper_check_planes() unconditionally.

One is the list of all connectors it could use, and that list already holds references for all the connectors. However the other list, or rather lists, is the one actively being used. That list is tracked per-crtc and currently doesn't hold any extra references. Let's grab those extra references to avoid oopsing when the connector vanishes. The list of all possible connectors should get updated when the hpd happens, but the list of actively used connectors would not get updated until the next time the fb-helper picks through the set of possible connectors. And so we need to hang on to the connectors until that time. Since we need to clean up in drm_fb_helper_crtc_free() as well, let's pull the code to a common place. And while at it let's pull in up the modeset->mode cleanup in there as well. The case of modeset->fb is a bit less clear. I'm thinking we should probably hold a reference to it, but for now I just slapped on a FIXME. v2: Cleanup things drm_fb_helper_crtc_free() too (Chris) v3: Don't leak modeset->connectors (Chris) Cc: Chris Wilson Cc: stable@vger.kernel.org Cc: Carlos Santa Cc: Kirill A.
