-Subject: drm/fsl-dcu: Convert to Linux IRQ interfaces
-
-From: Thomas Zimmermann <tzimmermann@suse.de>
-
-[ Upstream commit 03ac16e584e496230903ba20f2b4bbfd942a16b4 ]
-
-Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's
-IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers
-don't benefit from using it. DRM IRQ callbacks are now being called
-directly or inlined.

-Subject: drm/fsl-dcu: Use drm_fbdev_generic_setup()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Noralf Trønnes <noralf@tronnes.org>
-
-[ Upstream commit f4d26fa9136427d3cb2959cee13e0900b8004850 ]
-
-The CMA helper is already using the drm_fb_helper_generic_probe part of
-the generic fbdev emulation. This patch makes full use of the generic
-fbdev emulation by using its drm_client callbacks. This means that
-drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are
-now handled by the emulation code. Additionally fbdev unregister happens
-automatically on drm_dev_unregister().
-
-The drm_fbdev_generic_setup() call is put after drm_dev_register() in the
-driver. This is done to highlight the fact that fbdev emulation is an
-internal client that makes use of the driver, it is not part of the
-driver as such. If fbdev setup fails, an error is printed, but the driver
-succeeds probing.

-Create GEM objects with drm_gem_cma_create_object_default_funcs(), which
-allocates the object and sets CMA's default object functions. Corresponding
-callbacks in struct drm_driver are cleared. No functional changes are made.
-
-Driver and object-function instances use the same callback functions, with
-the exception of vunmap. The implementation of vunmap is empty and left out
-in CMA's default object functions.

-v3:
- * convert to DRIVER_OPS macro in a separate patch

-Subject: drm/i915/gtt: Enable full-ppgtt by default everywhere
-
-From: Chris Wilson <chris@chris-wilson.co.uk>
-
-[ Upstream commit 79556df293b2efbb3ccebb6db02120d62e348b44 ]
-
-We should we have all the kinks worked out and full-ppgtt now works
-reliably on gen7 (Ivybridge, Valleyview/Baytrail and Haswell). If we can
-let userspace have full control over their own ppgtt, it makes softpinning
-far more effective, in turn making GPU dispatch far more efficient by
-virtue of better mm segregation. On the other hand, switching over to a
-different GTT for every client does incur noticeable overhead, but only
-for very lightweight tasks.
