[PATCH v5 00/80] drm: Provide client setup helper and convert drivers

Provide drm_client_setup() to initialize in-kernel DRM clients. Then
convert all drivers to the new interface. Remove old interfaces for
the fbdev client.

So far, the only supported DRM client in the kernel is for fbdev
emulation with its fbcon support. Long term, we want to move away
from fbcon. Possible replacements are DRM-based loggers, boot-up
logos or maybe even a console. The exact kind of client should be
configurable by the user. You can find examples of such clients at
[1] and [2].

To do this, we need one single interface for drivers to initialize
the configured in-kernel clients, replacing the current call to
initialize fbdev emulation. The fbdev emulation also depends on the
DRM driver's management, so drivers differ in what fbdev code they
run. We need to abstract this as well.

This patchset addresses these topics. While there are many patches,
most of them are small, straight-forward changes to drivers or
rearrange existing code.

Patches 1 to 3 add a driver-neutral setup function for the fbdev
client. The new callback fbdev_probe in struct drm_driver creates
the GEM buffer for fbdev output. It replaces the existing callback
fb_probe from struct drm_fb_helper_funcs, which currently does the
same. The client code is equal to code in exisisting fbdev emulation,
except for its use of fbdev_probe.

Patch 4 adds drm_client_setup(), a client-agnostic interface to
initialize the in-kernel DRM clients. It only supports the new fbdev
emulation setup, but additional clients will be added here. Hopefully
this will hide future changes to DRM client initialization from
drivers. DRM drivers with support for DRM's default clients now have
to select DRM_CLIENT_SELECTION. This Kconfig option will later control
the details of selecting client code and modules.

Patches 5 to 48 rework all drivers with GEM memory management based
on DMA helpers. This is fairly straigh-forward. The fbdev-dma helpers
provide an implementation of the fbdev_probe helpers. Each driver
sets the new callback in its instance of struct drm_driver and calls
drm_client_setup(). Then the old fbdev-dma client goes away.

Patches 49 to 62 do the same for drivers with SHMEM-based GEM memory
management. The fbdev client code is again the same as before, except
for the fbdev_probe callback.

Patches 63 to 72 do the same for drivers with TTM-based GEM memory
management.

Patches 73 to 80 do the same for most of the remaining drivers with
custom fbdev emulation. As before, the new fbdev client code is mostly
the same the old one; except for the fbdev_probe function.

Changes for i915 and xe are a bit more involved, so they are left out
for now and will be send in a separate series.

This patchset has been tested on various hardware with the various
memory managers involved.

v5:
- add DRM_CLIENT_SELECTION and DRM_CLIENT_SETUP to Kconfig and update
  drivers accordingly
v4:
- drop unneeded changes to panel/ili9341
- fix docs
v3:
- add missing macros for driver ops (Sam)
- split off i915/xe changes
v2:
- add drm_client_setup_with_fourcc()
- xe: set fbdev_probe in xe_display_driver_set_hooks()
- do cleanups

[PATCH v5 01/80] drm/fbdev-helper: Move color-mode lookup into 4CC format helper

The color mode as specified on the kernel command line gives the user's
preferred color depth and number of bits per pixel. Move the
color-mode-to-format conversion from fbdev helpers into a 4CC helper,
so that it can be shared among DRM clients.

v2:
- fix grammar in commit message (Laurent)

[PATCH v5 02/80] drm/fbdev-helper: Set and clear VGA switcheroo client from fb_info

Call vga_switcheroo_client_fb_set() with the PCI device from the
instance of struct fb_info. All fbdev clients now run these calls.
For non-PCI devices or drivers without vga-switcheroo, this does
nothing. For i915 and radeon, it allows these drivers to use a
common fbdev client.

The device is the same as the one stored in struct drm_client and
struct drm_fb_helper, so there is no difference in behavior. Some
NULL-pointer checks are being removed, where those pointers cannot
be NULL.

v4:
- clarify call semantics for drm_fb_helper_unregister_info() (Javier)

[PATCH v5 03/80] drm/fbdev: Add memory-agnostic fbdev client

Add an fbdev client that can work with any memory manager. The
client implementation is the same as existing code in fbdev-dma or
fbdev-shmem.

Provide struct drm_driver.fbdev_probe for the new client to allocate
the surface GEM buffer. The new callback replaces fb_probe of struct
drm_fb_helper_funcs, which does the same.

To use the new client, DRM drivers set fbdev_probe in their struct
drm_driver instance and call drm_fbdev_client_setup(). Probing and
creating the fbdev surface buffer is now independent from the other
operations in struct drm_fb_helper. For the pixel format, the fbdev
client either uses a specified format, the value in preferred_depth
or 32-bit RGB.

v2:
- test for struct drm_fb_helper.funcs for NULL (Sui)
- respect struct drm_mode_config.preferred_depth for default format

[PATCH v5 04/80] drm: Add client-agnostic setup helper

DRM may support multiple in-kernel clients that run as soon as a DRM
driver has been registered. To select the client(s) in a single place,
introduce drm_client_setup().

Drivers that call the new helper automatically instantiate the kernel's
configured default clients. Only fbdev emulation is currently supported.
Later versions can add support for DRM-based logging, a boot logo or even
a console.

Some drivers handle the color mode for clients internally. Provide the
helper drm_client_setup_with_color_mode() for them.

Using the new interface requires the driver to select
DRM_CLIENT_SELECTION in its Kconfig. For now this only enables the
client-setup helpers if the fbdev client has been configured by the
user. A future patchset will further modularize client support and
rework DRM_CLIENT_SELECTION to select the correct dependencies for
all its clients.

v5:
- add CONFIG_DRM_CLIENT_SELECTION und DRM_CLIENT_SETUP
v4:
- fix docs for drm_client_setup_with_fourcc() (Geert)
v3:
- fix build error
v2:
- add drm_client_setup_with_fourcc() (Laurent)
- push default-format handling into actual clients

[PATCH v5 05/80] drm/fbdev-dma: Support struct drm_driver.fbdev_probe

Rework fbdev probing to support fbdev_probe in struct drm_driver
and reimplement the old fb_probe callback on top of it. Provide an
initializer macro for struct drm_driver that sets the callback
according to the kernel configuration.

This change allows the common fbdev client to run on top of DMA-
based DRM drivers.

[PATCH v5 11/80] drm/atmel-hdlcd: Run DRM default client setup

Call drm_client_setup_with_fourcc() to run the kernel's default client
setup for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

v5:
- select DRM_CLIENT_SELECTION
v3:
- add DRM_FBDEV_DMA_DRIVER_OPS macro (Sam)
v2:
- use drm_client_setup_with_fourcc()

[PATCH v5 13/80] drm/hisilicon/kirin: Run DRM default client setup

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The kirin driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

[PATCH v5 19/80] drm/imx/dcss: Run DRM default client setup

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The dcss driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

[PATCH v5 27/80] drm/meson: Run DRM default client setup

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The meson driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

[PATCH v5 49/80] drm/fbdev-shmem: Support struct drm_driver.fbdev_probe

Rework fbdev probing to support fbdev_probe in struct drm_driver
and reimplement the old fb_probe callback on top of it. Provide an
initializer macro for struct drm_driver that sets the callback
according to the kernel configuration.

This change allows the common fbdev client to run on top of SHMEM-
based DRM drivers.

[PATCH v5 50/80] drm/ast: Run DRM default client setup

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The ast driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

v5:
- select DRM_CLIENT_SELECTION

[PATCH v5 52/80] drm/cirrus: Run DRM default client setup

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The cirrus driver requests the same client pixel format as the value
stored in struct drm_mode_config.preferred_depth. The fbdev client
also looks at this value for the default pixel format. Thus remove
the format selection from cirrus.

[PATCH v5 64/80] drm/fbdev-ttm: Support struct drm_driver.fbdev_probe

Rework fbdev probing to support fbdev_probe in struct drm_driver
and reimplement the old fb_probe callback on top of it. Provide an
initializer macro for struct drm_driver that sets the callback
according to the kernel configuration.

This change allows the common fbdev client to run on top of TTM-
based DRM drivers.

The vboxvideo driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

[PATCH v5 73/80] drm/armada: Run DRM default client setup

Rework fbdev probing to support fbdev_probe in struct drm_driver
and remove the old fb_probe callback. Provide an initializer macro
for struct drm_driver that sets the callback according to the kernel
configuration.

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The armada driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

v5:
- select DRM_CLIENT_SELECTION
v4:
- revert an unrelated cleanup (Javier)

[PATCH v5 74/80] drm/exynos-drm: Run DRM default client setup

Rework fbdev probing to support fbdev_probe in struct drm_driver
and remove the old fb_probe callback. Provide an initializer macro
for struct drm_driver that sets the callback according to the kernel
configuration.

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The exynos-drm driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

v5:
- select DRM_CLIENT_SELECTION
v4:
- revert an unrelated cleanup (Javier)

[PATCH v5 77/80] drm/radeon: Run DRM default client setup

Rework fbdev probing to support fbdev_probe in struct drm_driver
and remove the old fb_probe callback. Provide an initializer macro
for struct drm_driver that sets the callback according to the kernel
configuration.

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The radeon driver specifies a preferred color mode depending on
the available video memory, with a default of 32. Adapt this for
the new client interface.

v5:
- select DRM_CLIENT_SELECTION
v2:
- style changes

[PATCH v5 79/80] drm/omapdrm: Remove struct drm_fb_helper from struct omap_fbdev.

Store instances of drm_fb_helper and struct omap_fbdev separately.
This will allow omapdrm to use the common fbdev client, which allocates
its own instance of struct drm_fb_helper.

There is at most one instance of each per DRM device, so both can be
referenced directly from the omap and DRM device structures. A later
patchset might rework the common fbdev client to allow for storing
both, drm_fb_helper and omap_fbdev, together in the same place.

[PATCH v5 80/80] drm/omapdrm: Run DRM default client setup

Rework fbdev probing to support fbdev_probe in struct drm_driver
and remove the old fb_probe callback. Provide an initializer macro
for struct drm_driver that sets the callback according to the kernel
configuration.

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The omapdrm driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

v5:
- select DRM_CLIENT_SELECTION
