The legacy path implements setcmap in terms of crtc .gamma_set. The atomic path implements setcmap by directly updating the crtc gamma_lut property. This has a couple of benefits: - it makes the redundant fb helpers .load_lut, .gamma_set and .gamma_get completely obsolete. They are now unused and subject for removal. - atomic drivers that support clut modes get fbdev support for those from the drm core. This includes atmel-hlcdc, but perhaps others as well?

The function has little to do with atomic, it's just where it has so far been needed. So, rename it to drm_property_replace_blob, move it to drm_property.c and export it. Change the semantics to return whether the blob was replaced instead of using an extra argument for that. Signed-off-by:

Make the atomic private object stuff less special by introducing proper base classes for the object and its state. Drivers can embed these in their own appropriate objects, after which these things will work exactly like the plane/crtc/connector states during atomic operations. v2: Reorder to not depend on drm_dynarray (Daniel) Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> #v1 Signed-off-by:

You can enable the CRTC and without adding the plane to the state and it will succeed. This should be prevented in the crtc check instead of the plane check, because the plane check may never run for atomic enable, but the crtc check always will. This is based on a similar check in vmwgfx. Signed-off-by:

If the DRM core fails to init for whatever reason, ensure that no driver ever calls drm_dev_register(). This is best done at drm_dev_init() as it covers drivers that call drm_dev_alloc() as well as drivers that prefer to embed struct drm_device into their own device struct and call drm_dev_init() themselves. In my case I had so many dynamic device majors used that the major number for DRM (226) was stolen, causing DRM core init to fail after failing to register a chrdev, and ultimately calling debugfs_remove() on drm_debugfs_root in drm_core_exit(). After drm core failed to init, VGEM was still calling drm_dev_register(), ultimately leading to drm_debugfs_init(), with drm_debugfs_root passed as the root for the new debugfs dir at debugfs_create_dir(). This led to a kernel panic once we were either derefencing root->d_inode while it was NULL or calling root->d_inode->i_op->lookup() while it was NULL in debugfs at inode_lock() or lookup_*().

Like with panning and modesetting, and like with those, stick with simple drm_modeset_locking_all for the legacy path, and the full atomic dance for atomic drivers. This means a bit more boilerplate since setting up the atomic state machinery is rather verbose, but then this is shared code for 30+ drivers or so, so meh. After this patch there's only the LUT/cmap path which is still using drm_modeset_lock_all for an atomic driver. But Peter is already locking into reworking that, so I'll leave that code as-is for now. v2: Squash in patches from Maarten to unify all the various atomic paths into just one atomic update function for fbdev overall. On top do one s/restore_fbdev_mode/restore_fbdev_mode_atomic/ so that we have all-atomic callchains after the first check.

Those are now all protected using fb_helper->lock. v2: We still need to hold mode_config.mutex right around calling connector->fill_modes. v3: I forgot to hold mode_config.mutex while looking at connector->status and the mode list. Also, we need to patch up the i915 ->initial_config callback to grab the locks it needs to inspect the modeset state recovered from the fw. v4: Don't reorder the probe too much (Ville).

Like with the drm-native vblank wait ioctl we can entirely rely on the spinlocks in drm_vblank.c, no need at all to take expensive mutexes. The only reason we had to take mode_config.mutex was to protect the fbdev helper's data-structures, but that's now done by fb_helper->lock.
