The vkms driver does not need to create a platform device, as there is
no real platform resources associated it, it only did so because it was
simple to do that in order to get a device to use for resource
management of drm resources. Change the driver to use the faux device
instead as this is

Hi Louis,

I'm not well versed in YUV color formats, so I did my best reading the kernel
documentation before reviewing this series... But I'll most likely ask some

Add support for pixel format ABGR, which is the default format
on Android devices. This will allow us to use VKMS as the default
display driver in Android Emulator (Cuttlefish) and increase VKMS
adoption.

In preparation for ConfigFS support, a flexible way to configure VKMS device(s)
is required.
This series adds the required APIs to create a configuration, the code changes
required to apply it and KUnit test validating the changes.

controllable when CONFIG_DRM_USE_DYNAMIC_DEBUG=y by telling dyndbg

To allows the userspace to test many hardware configuration, introduce a
new interface to configure CRTCs and encoders.
The CRTCs and encoders are created in their own directory. To link the
CRTC, symlinks are used in the `possible_crtcs` folders.
The current interface is:
/config/vkms
In order to support multiple configuration, add the possibility to change
the encoder type.

To allows the userspace to test many hardware configuration, introduce a

The type of a connector can be changed by editing the file type and by
writing the connector type number.

To allows the userspace to test many hardware configuration, introduce a
new interface to configure the available formats per planes. VKMS
supports many formats, so the userspace can choose any combination of
them.
The supported formats are configured by writing in the file
supported_formats
As a connector can be connected and disconnected once a device is created,
create a file to allow changing this status.

To allows the userspace to test many hardware configuration, introduce a
new interface to configure the available rotation per planes. VKMS
supports any rotation and reflection, so the userspace can choose any
combination.
The supported rotations are configured by writing a rotation bitmask to
VKMS is manly used to test userspace program and its behavior. The current
implementation is not very configurable as you can only have one device,
with few specific planes.
This is the introduction of a basic interface to dynamically create new
devices.
The new interface is:
/config/vkms
In preparation for introduction of ConfigFS support, expose the
vkms_destroy/create helper to remove a vkms device.
