The original rationale for commit cd456f8d ("drm: Restrict stackdepot usage to builtin drm.ko") was that depot_save_stack() (which is what we used back then) wasn't exported. stack_depot_save() (which is what we use now) is exported however, so relax the dependency allow CONFIG_DRM_MM_DEBUG with DRM=m.

The name of the structure drm_atomic_state is confusing. Let's add an entry to our todo list to rename it. Reviewed-by:

The current documentation of drm_atomic_state says that it's the "global state object". This is confusing since, while it does contain all the objects affected by an update and their respective states, if an object isn't affected by this update it won't be part of it. Thus, it's not truly a "global state", unlike object state structures that do contain the entire state of a given object. Reviewed-by:

Commits 63e83c1d ("drm: Consolidate connector arrays in drm_atomic_state"), b8b5342b ("drm: Consolidate plane arrays in drm_atomic_state") and 5d943aa6 ("drm: Consolidate crtc arrays in drm_atomic_state") moved the object pointer and their state pointer to an intermediate structure storing both. The CRTC commit didn't update the doc of the crtcs field to reflect that, and the doc for the planes and connectors fields mention that they are pointers to an array of structures with per-$OBJECT data. The private_objs field was added later on by commit b430c27a ("drm: Add driver-private objects to atomic state") reusing the same sentence than the crtcs field, probably due to copy and paste. While these fields are indeed pointers to an array, each item of that array contain a pointer to the object structure affected by the update, and its old and new state. There's no per-object data there, and there's more than just a pointer to the objects. Let's rephrase those fields a bit to better match the current situation. Acked-by:

Commit 63e83c1d ("drm: Consolidate connector arrays in drm_atomic_state") removed the connector_states field but didn't remove its mention in the num_connectors documentation. Acked-by:

Some fields of drm_atomic_state have been documented in-line, but some were documented in the main kerneldoc block before the structure. Since the former is the preferred option in DRM, let's move all the fields to an inline documentation. Acked-by:

Every time QAIC_MMAP_BO ioctl is called for a BO, drm_gem_create_mmap_offset() is called. Calling drm_gem_create_mmap_offset() more then once for a BO seems redundant. Signed-off-by:

The pm_runtime_enable function increases the power disable depth, which means that we must perform a matching decrement on the error handling path to maintain balance within the given context. Additionally, we need to address the same issue for pm_runtime_get_sync. We fix this by invoking pm_runtime_disable and pm_runtime_put_sync when error returns.
