We don't need this anymore. Since we only support one output,

If an output exists, it should be cleaned up automatically when we release

By the time we get to this failure we may (or may not) have implanted a
listener.
freerdp_listener_free() safely handles passed NULL pointers, so we don't
have to add any additional checks on our end.

The RDP backend wants to be able to change scale for existing outputs,
so try to hook this up mostly in the same way a mode switch works.

When changing to/from the native mode, or when changing the native
mode we need to damage the changed output to ensure it's redrawn.

Some backends have special head specific state that doesn't fit into the
existing generic head setter functions, and is too specific to make more
functions for.
RDP's primary output flag is an example.

We are assuming that CRTC_CTM is pass-through, so better ensure it

We are assuming that CRTC_DEGAMMA_LUT is pass-through, so better ensure
it really is pass-through rather than whatever the previous KMS client

This too falls under deprecated_gamma_is_set check, because the legacy

We are assuming that gamma LUT is pass-through, so better ensure it
really is pass-through rather than whatever the previous KMS client left
there.
Unfortunately the legacy ioctl does not offer any way to reset the LUT
without actually crafting an identity LUT.
If the legacy gamma libdrm function indicates the feature is not
supported, do not try to use it again. This avoids hammering the legacy
gamma every frame when deprecated drm_output_set_gamma() is not used.
drm_output_set_gamma() is not updated to check/set this flag in order to
maintain its old behavior.

We are assuming that CRTC_GAMMA_LUT is pass-through, so better ensure it
really is pass-through rather than whatever the previous KMS client left
there.
Unfortunately, we have old drm_output_set_gamma() API that cms-static
and cms-colord plugins are using. To avoid trampling over them, do not
touch gamma after they did. Those plugins are deprecated, so there is no
reason to make set_gamma work through atomic.
drm_output_set_gamma() is called from weston_compositor_add_output()
through the output_created_signal. This is after drm_output_enable() and
before any KMS modeset or atomic commit on the CRTC. Therefore it is not
possible that there would be any KMS action in flight when
drm_output_set_gamma() is called, and so setting deprecated_gamma_is_set
should be non-racy - like setting CRTC_GAMMA_LUT itself.

Move the debug printing before the bail-out if the property does not
exist. This means that trying to set a missing property will be logged,
and it can be identified by the property id being 0.
We are starting to program more KMS properties, and if KMS state
building fails, this gives better chances to figure out what happened.
For example, if we accidentally assume that some property always exists
when it doesn't.

Rather than reinventing --use-pixman and --use-gl throughout each
backend, just have a common --renderer=foo argument which can be used to
explicitly specify the renderer.
The old arguments are still handled for backwards compatibility.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Add an explicit request to the backend config to choose the renderer.
Currently, only Pixman remains supported, with auto defaulting to that.

When we're selecting our renderer, use the enum rather than two
mutually-exclusive booleans to not use the no-op renderer.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Add an 'auto' or unspecified renderer type, so we can use enum
weston_renderer_type during the configuration stage, where the target
renderer may be unspecified or unknown.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Similar to the backend type, also expose the renderer type enum as ABI.
This makes it possible to implement a more consistent config API, as
opposed to every backend hand-rolling its own use-the-other-one bool.
The enums are explicitly numbered to avoid 0, so 0 can be used as a
'not-specified' sentinel value to allow backwards compatibility with the
old config interfaces.

This fixes a problem that can be seen with Firefox running under xwayland.
- Start it (or another client that remembers its size and maximized state),
- resize it
- maximize it
- exit it
- restart it
- unmaximize it
The size will be changed to a default size and not the previous unmaximized
size.
To fix this, save the unmaximized height and width like we do for the
fullscreen case.
