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/
headers.
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.

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.
The "bad" include style was found with:
$ for h in shared/*.h; do git grep -F $(basename $h); done | grep -vF '"shared/'

If configless_context is not supported, we pick one EGLConfig as the "base
config" because we have just one GL context and different configs between the
context and EGLSurfaces might not work. Until now, we did not actually make
sure to pick the base config.
If the base config matches the requirements, prefer it. Only if it doesn't
match, go looking for another config.
This should give better chances of success on systems where configless_context
is not supported by relying less on eglChooseConfig().

If we don't have the surfaceless_context extension, we create a pbuffer as a
dummy surface to work with. If we also don't have configless_context, then it
is possible the config used for creating the context does not support pbuffers.
Therefore, if both conditions apply, we need to pick a config that supports
both window and pbuffer surfaces.
This makes the "base" config compatible, but it does not yet guarantee that we
actually pick it again when creating the pbuffer surface. Fixing that is
another patch.

Now that all backends pass in a list of acceptable DRM formats, that is used to
determine if the EGLConfig has an alpha channel or not. Therefore the
opaque_attribs and alpha_attribs are now useless, and we can remove the whole
config_attribs argument from the API.
gl_renderer_get_egl_config() uses an internal attrib list that matches at least
the union of the opaque_attribs and alpha_attribs matches.
Overall, behaviour should remain unchanged.
The new attribute array becomes variable in the future, so it is left
non-const.

Define a specific DRM format for the GL-renderer to render in. It goes through
fuzzy matching in egl-glue.c which ensures we get exactly the number of bits
for each channel, but does not require an exact format match.
This ensures we get the bit depth we expect instead of the first arbitrary
EGLConfig.
This should not change the current behaviour, because Mesa EGL takes care to
order the configs as apps expect.

Implement fuzzy EGLConfig pixel format matching, where we ensure that R, G, B
and A channels have the expected number of bits exactly. This is used on EGL
platforms where the EGLConfig native visual ID is not a DRM format code. On EGL
GBM platform, the old exact matching of native visual ID is kept.
As only the DRM backend uses a DRM format list for picking a config, this patch
should not change any behaviour.

Using arrays of pixel_format_info instead of just DRM format codes is useful
for fuzzy matching of formats with EGLConfigs in the future. The immediate
benefit is that we can easily print format names in log messages.
We should never deal with formats we don't have in our database, so discarding
unknown formats should be ok. Using unknown formats would become hard later,
too.

These fields are necessary when looking for an EGLConfig matching a pixel
format, but the configs do not expose a native visual id. Such happens on the
EGL surfaceless platform where one does not actually care about the exact pixel
format, one just cares it has the right number of bits for each channel and the
right component type.
FP16 formats are coming, so this paves way for them too, allowing them to be
described.
The FIXED/FLOAT terminology comes from EGL_EXT_pixel_format_float.

In an attempt to pull more of EGLConfig choosing into one place, refactor code
into the new gl_renderer_get_egl_config(). The purpose of this function is to
find an EGL config that not only satisfies the requested attributes and the
pixel formats if given but also makes sure the config is generally compatible
with the single GL context we have.
All this was already checked in gl_renderer_create_window_surface(), but
gl_renderer_create_pbuffer_surface() is still missing it. This patch is
preparation for fixing the pbuffer path.

Some drivers support EGL_EXT_image_dma_buf_import_modifiers for format
enumeration, but don't have any modifiers. In this case, on platforms where
malloc(0) returns non-NULL, we would leak that allocation to the caller.
Handle this by noticing when the number of supported modifiers is 0 and
returning early.
Some drivers expose the extension so they can expose
eglQueryDmaBufFormatsEXT, but don't support any modifiers. Treat this the
same as if the extension wasn't present.

compositor-fbdev: drop EGL support
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
When hotunplugging a display, the compositor will tear the top-level
wet_output object down, freeing its memory.
However, destruction of the backend output might be delayed in certain
situations (e.g. destroying DRM output while in the middle of a page
flip).
When the backend output is finally destroyed, it will trigger a
destruction callback previously added by the compositor, which point to
data belonging to the top-level wet_output object.
In order to avoid access to invalid data when the backend output is
destroyed after the top-level wet_output object, remove the destruction
callback from the corresponding list before freeing the object.

Currently drm-layer supports HDCP1.4 using connector property:
Content Protection. This property if available for a platform, can be
read and set for requesting content-protection.
Also, the patch series [1] adds HDCP2.2 support in drm, and patch [2]
adds support to send udev events for change in connector properties,
made by the kernel.
This patch adds these HDCP connector properties in weston, and exposes
the content-protection support to the client for drm-backend.
It adds the enums to represent 'Content Protection' and 'Content Type'
connector properties exposed by drm layer. It adds a member
'protection' in drm_output_state, to store the desired protection
from the weston_output in the drm-backend output-repaint cycle. This
is then used to write the HDCP connector properties for the drm_heads
attached to the drm_output.
The kernel sends uevents to the user-space for any change made by it
in the "Content Protection" connector property. No event is sent in
case of change in the property made by the user-space.
It means, when there is a change of the property value from "DESIRED"
to "ENABLE" i.e. successful authentication by the kernel, a uevent
will be generated, but in case of userspace requesting for disabling
the protection by writing "UNDESIRED" into the property, no uevent
will be generated.
This patch also adds support for handling new udev events for HDCP
connector property changes. Any such change, triggers change in the
weston_head's current_protection.

62626cbfec ensures that the GL render will not render a view's content
to the screen when the surface has requested a higher content-protection
level than the output currently offers.
When the HDCP MR was split into the core content-protection support in !83
and specific DRM support for HDCP in !48 (not yet landed), this opened a
hole where the DRM backend could promote a view to a hardware plane,
even if the output offered a lower protection level than the surface
wanted to enforce.
In the DRM backend, check the desired protection level, and refuse to
promote the view to a hardware plane if the output does not offer
sufficient protection. This will lead to presentation falling back to
the renderer, which may censor the content, reduce quality, etc.
