Some extensions (such as EGL_KHR_partial_update) add functions to EGL.
When the extension is present, GetProcAddress must return usable
function pointers for those entrypoints.
Assert that GetProcAddress returns a non-NULL function pointer in these
cases.

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.
Replace one more open-coded pixel format translation map with a call to our
central pixel format database, reducing duplication of format information.

No caller ever used anything but NULL here, so just use NULL to simplify code.
In fact, no EGL platform defined today even defines any platform attributes
except the X11 platform for choosing a non-default SCREEN.

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.

All these have the printf format string wrong. "%*s" sets the field width but
does not limit the string to len bytes. You need to set precision instead to
limit to len bytes: "%.*s".

In case of enforced protection mode, the renderer takes care of
censoring the protected content when the output recording is going on.
But in case of relaxed protection mode, the client must be notified to
avoid showing the protected content, if the output recording is on.
This patch handles the case, where the content-protection is enabled
with relaxed protection mode, and notifies the client, whenever the
recording is started or stopped.

Contents on an ouput are captured when screenshooter/recorder/screen

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.

The function pixman_blt may return false in case there is no
accelerated blit function available. In this case the remote shared
screen stays black.
This has been observed on Weston compiled for aarch64. In currrent
pixman 0.38.4 there is no accelerated pixman_blt function for
aarch64 available.
Use pixman_image_composite32 instead which is guaranteed to have a

and the recent update in weston to require 1.18, we can now safely

Commit 4fc5dd0099 ("compositor: add capability CAPTURE_YFLIP")
introduced a capability flag which indicates whether y-flipping is
necessary. As already indicated in that commit message, it seems
that pixman flipps the y-axis only due to historic reasons.
Drop y-flipping and use the WESTON_CAP_CAPTURE_YFLIP flag to
indicate that y-flipping is not necessary. This simplifies code
and improves screen share performance (on my test by about 3% down
to 18% CPU load on the sharing instance of Weston).
