This driver has no way to handle damage, the reason the drm_gem_fb_create_with_dirty() was used was because I had the ambition that the driver would only send out updates to DSI command displays whenever something changed, so as to minimize traffic. It turns out this ambition with command mode isn't working in practice because all the MCDE does is to create a continuous stream of DSI commands and while it is possible to send single frame updates with it, it's not been worthwhile. So we are just setting up continuous updates. Reported-by:

Implement fbdev emulation that is optimized for drivers that use DMA helpers. The buffers may no tbe moveable, may not require damage handling and have to be located in system memory. This allows fbdev emulation to operate directly on the buffer and mmap it to userspace. Besides those constraints, the emulation works like in the generic code. As an internal DRM client provides, it receives hotplug, restore and unregister events. The DRM client is independent from the fbdev probing, which runs on the first successful hotplug event. The emulation is part of the DMA helper module and not build unless DMA helpers and fbdev emulation has been configured. Tested with vc4. Signed-off-by:

Some of these dependencies used to be sensible when only a small part of the platforms supported by ARCH=arm could be compiled together in a single kernel image. Nowadays ARCH_MULTIPLATFORM is only used as a guard for kernel options incompatible with a multiplatform image. See commit 84fc8636 ("ARM: make ARCH_MULTIPLATFORM user-visible") for some more details. Signed-off-by:

Christian Hergert reports that the driver doesn't enable the property and that leads to always doing a full plane update, even when the driver does support damage clipping for the primary plane. Don't enable it for the cursor plane, because its .atomic_update callback doesn't handle damage clips. Reported-by:

The hardware settings for color format and pitch are state of the primary plane. Store the values in the primary plane's state structure struct cirrus_primary_plane_state. Adapt all callers. All fields in struct cirrus_device are now considered immutable after initialization. Plane updates consider the difference between the old and the new plane state before updating format or pitch.
