The RDP-backend is reporting a non-zero physical size
value, and there are some clients that get the resolution
in pixels directly from the physical size reported. This
leads to a resolution of 25.4 PPI (or 1px/1mm), which is too
small.
But there's no need for that. The physical size is reported
on enabling the output (in the case of RDP-backend we have
no information about it before this), and the resolution is
already set in this moment.
Report a zero physical size to compositor, what makes frontend
and clients use their default values and applications become
readable.

When the aspect-ratio-aware mode support was added to Weston, it was
done before the libdrm support was finalised and merged. Between it
being added to Weston and being merged, it changed to no longer provide
the offset for the bitmask.
Instead of using the mask and a compatible enum, if we update our
libdrm dependency, we can use the flag definitions directly from libdrm.
In 94e4068ba1, the libdrm dependency was bumped to 2.4.83, which
enabled us to remove a bunch of error-prone ifdefs by making atomic and
modifier support mandatory.
We determined in the discussion of !311 that it was safe to push the
dependency as high as 2.4.91, as that was what was available in major
distributions.
Bumping to 2.4.86 allows us to safely remove the ifdef and go with
upstream flags, as that was added in mesa/drm@0d889201d1.

Mode change from mixed-mode to renderer-only means we should no longer

This introduces a new convention of checking through the compositor destroy
listener if the plugin is already initialized. If the plugin is already
initialized, then the plugin entry function succeeds as a no-op. This makes it
safe to load the same plugin multiple times in a running compositor.
Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.
All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
did not fit there.
Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.
Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.

This comment was added in 230f3b1bf8 with the
intent that if we had an information table about pixel formats (which we do
have today), we could implement more sanity checks like ensuring that width
pixels fit into stride.
Daniel Vetter said on #dri-devel IRC recently:
< danvet> since userspace shouldn't look at stride for buffers with
modifiers, only pass it around unchanged
I asked for clarification. It was expected that userspace would not do any kind
of sanity checks as modifiers could change everything.
Let's remove the misleading code comment so that people don't get the idea of
adding more well-intended but ill-advised sanity checks. If more checks are
added, they must take the modifier into account, which the existing checks do
not do.
After 5 years, it is far too late to remove our existing sanity checks, but we
can attempt to not cause any more damage that would restrict what people can do
in the kernel.

Define common_inc which includes both public_inc and the project root directory.
The project root directory will allow access to config.h and all the shared/

Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common
#include directive style, as e.g. including shared/ headers without the
subdirectory name no longer works.
Unfortunately this does not prevent one from using private libweston headers
with the usual include pattern for public headers.
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
When all shared/ headers are included in the same way, we can drop unnecessary
include seach paths from the compiler.
This include style was chosen because it is prevalent in the code base. Doing
anything different would have been a bigger patch.
This also means that we need to keep the project root directory in the include
search path, which means that one could accidentally include private headers
with
#include "libweston/dbus.h"
or even
#include <libweston/dbus.h>
IMO such problem is smaller than the churn caused by any of the alternatives,
and we should be able to catch those in review. We might even be able to catch
those with grep in CI if necessary.
