1a11abc821 [platforms/x11/standalone] Port to AbstractOutput
Summary:
Represent outputs in the X11 session via AbstractOutput. For that we
move all Wayland specific parts of AbstractOutput into a new subclass
AbstractWaylandOutput and let the outputs of our Wayland backends inherit
from there.

This should allow us to get rid of the Screens class later on.

Test Plan: Manually in X session.

2e20cac5e2 [platforms/fbdev] Port to AbstractOutput
Summary:
To homogenize our backends and as another step to remove the Screens class
use the AbstractOutput class in the framebuffer backend.

Test Plan: Manually on VT enforcing the framebuffer backend.

304528e80b [platforms/fbdev] Attempt to set the framebuffer color layout on the framebuffer device
Summary:
Weston does something similar
https://cgit.freedesktop.org/wayland/weston/tree/libweston/compositor-fbdev.c#n315
 ...and it seems that the non-primary framebuffer devices start completely off. (the screen is off on my Displayport device, and the window for the second vga card in qemu is much smaller than the primary one, and all black for my qemu vm) .

In my testing, sending the ioctl FBIOPUT_VSCREENINFO with a *changed* &varinfo allows it to wake up, and turns on the screen.
doing FBIOGET_VSCREENINFO and then FBIOPUT_VSCREENINFO in my testing does not work.

I think really the values that end up getting changed are varinfo.transp.offset and varinfo.transp.length. at least on the qemu system, but in this patch I am aligning all of them for completeness, because the drivers might do it differently for qemu

Test Plan: This causes the window for /dev/fb1 (remote-viewer, and a qemu vm with two "VGA" (bochsdrm) cards) to resize from the smaller size when specifying it as the --fb-device on seat0, and kwin draws on the device.

09489a4c2b Add a pure virtual method to Platform to describe the supported compositors
Summary:
So far KWin does not know which Compositors the platform actually
supports. This results in KWin happily trying to use the OpenGL
compositor on fbdev or the QPainter compositor on hwcomposer although
that is obviously going to fail as the platform doesn't support this.

By adding a pure virtual method all Platforms can define what they
support. In a later step the Compositor can use this to create an
appropriate scene and also perform proper fallback handling in case the
scene creation fails.

Test Plan: Compiles

aaf8ce16df [platforms/fbdev] Properly detect a BGR image format
Summary:
If the format of the framebuffer is BGR we cannot create an RGB image
format from it - the rendering is incorrect. Unfortunately QImage does
not support a BGR image format.

To solve this problem we still use an RGB image format but on rendering
the front buffer is rgbSwapped to convert the RGB image to a BGR image.

BUG: 365243
FIXED-IN: 5.7.2

Test Plan: Tested on a neon kvm

2bff90976e Move backends/ to plugins/platforms/
Summary:
Source code reorganization:
The base class AbstractBackend got renamed to Platform, thus the
"backends" are "platforms" now. As they are plugins they should go
together with other KWin plugins which are nowadays in the folder
plugins.

So new location is plugins/platforms/
