This moves the creation of the blob to be earlier, to when the damage is

with the blob id itself.
This should stop creating new blob ids for TEST_ONLY commits, and them

In the test suite we may want to run a DRM-backend test on a
non-default seat, which may not have a input device associated.
Weston's default behavior is to not open if input devices are
not found, as it may cause troubles. For instance, Weston can
open but if no input device is set than the user can not
interact or leave it.
Add flag --continue-without-input to DRM-backend so we can run
these types of tests with no input. Notice that this won't force
the compositor to skip opening a input device if it finds it on
the non-default seat.

All timeline event timestamps are in CLOCK_MONOTONIC already. DRM KMS
timestamps are practically guaranteed to be CLOCK_MONOTONIC too, even though
presentation clock could theoretically be something else. For other backends,
the presentation clock is likely CLOCK_MONOTONIC_RAW due to
weston_compositor_set_presentation_clock_software().
This patch ensures that the recorded vblank timestamp is in CLOCK_MONOTONIC.
Otherwise interpreting the timeline traces might be difficult to do accurately,
since it would be hard to recover the relationship between the presentation
clock and timeline event timestamps.
The time conversion routine is the simplest possible, I don't think we need any
more accurate conversion for timeline purposes. Besides, DRM-backend is the
only backend where the timings actually matter, the other backends are
software-timed anyway.
Since the clock domain of the "vblank" attribute potentially changes, the
attribute is renamed. Wesgr never used this attribute.

If a surface has subsurfaces then the surface itself is in the subsurface
list. To avoid printing it again there is a check to skip the child view,
if it is the same as the current view.
However, this fails when a surface with subsurfaces has two (or more) views:
The check to skip the parent fails for the other view and the two views are
printed again and again until a stack overflow occurs.
So instead check if the parent view of the subsurface view is the current
view. This way, any view that does not belong to a real subsurface is
skipped.
As a side effect, this ensures that each view of the subsurfaces is only
printed once at the correct place in the hierarchy.

The renderer buffer size is usually the same size as the current mode,
so we were taking the dimensions from the currently-set mode. However,
using current_mode is quite confusing in places when it comes to scale,
and it also hampers our ability to do mode switches, as well as to
introduce a future option which will let the renderer use a smaller
buffer than the output and display scaled.
Simply take the dimensions of the renderer's output buffer from the

This condition inside drm_output_render() checks if we can reuse the
existing renderer buffer for the primary plane; this occurs in
mixed-mode composition where a client buffer promoted to a plane has
changed, but the primary plane is unchanged.
We accomplish this by checking if there is no damage on the
primary/renderer plane, and then if there is already a renderer buffer
active on the primary plane: in that case, we can reuse the buffer we
already have.
There was a further condition checking if the width and height were
identical. This was designed to prevent against issues on mode changes.
However, runtime mode changes are already quite broken, and a mode
change will also cause damage on the full plane. We can simply remove
this condition.

When weston-desktop-shell uses a solid color for the wallpaper, it creates a
1x1 buffer and uses wp_viewport to scale that up to fullscreen. It's a very
nice memory saving optimization.
If you also have output scale != buffer scale, it means pixman-renderer chooses
bilinear filter. Arguably pixman-renderer should choose bilinear filter also
when wp_viewport implies scaling, but it does not. As w-d-s always sets buffer
scale from output scale, triggering the bilinear filter needs some effort.
What happens when you sample with bilinear filter from a 1x1 buffer, stretching
it to cover a big area? Depends on the repeat mode. The default repeat mode is
NONE, which means that samples outside of the buffer come out as (0,0,0,0).
Bilinear filter makes it so that every sampling point on the 1x1 buffer except
the very center is actually a mixture of the pixel value and (0,0,0,0). The
resulting color is no longer opaque, but the renderer and damage tracking
assume it is. This leads to the issue 373.
Fix half of the issue by using repeat mode PAD which corresponds to OpenGL
CLAMP_TO_EDGE. GL-renderer already uses CLAMP_TO_EDGE always.
This is only a half-fix, because composite_clipped() cannot actually be fixed.
It relies on repeat mode NONE to work. It would need a whole different approach
to rendering potentially non-axis-aligned regions exactly like GL-renderer.

It was discovered in issue #99 that the implementations of the 90 and 270
degree rotations were actually the inverse of what the Wayland specification
spelled out. This patch fixes the libweston implementation to follow the
specification.
As a result, the behaviour of the the weston.ini transform key also changes. To
force all users to re-think their configuration, the transform key values are
also changed. Since Weston and libweston change their behaviour, the handling
of clients' buffer transform changes too.
All the functions had their 90/270 cases simply swapped, probably due to
confusion of whether WL_OUTPUT_TRANSFORM_* refers to rotating the monitor or
the content.
Hint: a key to understanding weston_matrix_rotate_xy(m, c, s) is that the
rotation matrix is formed as
c -s
s c
that is, it's column-major. This fooled me at first.
Fixing window.c fixes weston-terminal and weston-transformed.
In simple-damage, window_get_transformed_ball() is fixed to follow the proper
transform definitions, but the fix to the viewport path in redraw() is purely
mechanical. The viewport path looks broken to me in the presence of any
transform, but it is not this patch's job to fix it.
Screen-share fix just repeats the general code fix pattern, I did not even try
to understand that bit.

When using weston-launch launcher deactivating the VT is sometimes
racy and leads to Weston still being displayed. The launcher-direct.c
backend makes sure that the session signal is emitted first, then DRM
master is dropped and finally the VT switch is acknowledged via
VT_RELDISP.
However, in the weston-launch case the session signal is emitted via
a socket message to the weston process, which might get handled a bit
later. This leads to dropping DRM master and acknowledging the VT
switch prematurely.
Add a socket message which allows weston to notify weston-launch that
the signal has been emitted and deactivating can be proceeded.

On weston-launch exit we see errors such as:

failed to set KD_TEXT mode on tty: Invalid argument
This has been resolved by making sure the tty file descriptor

and VT_SETMODE still fail with -EIO:
failed to restore keyboard mode: Input/output error
failed to set KD_TEXT mode on tty: Input/output error
It turns out the reason for this lies in some very particular
behavior of the kernel, the separation of weston-launch/weston
and the fact that we restore the tty only after the weston
process quits: When the controlling process for a TTY exits,
all open file descriptors for that TTY are put in a hung-up
state! For more details see this systemd-logind issue:

When the aspect-ratio-aware mode support was added to Weston, it was

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.

Mode change from mixed-mode to renderer-only means we should no longer
try to place views in HW planes (as we composite everything into the
primary plane) thus we should avoid that whenever that happens.
In the same time we need to be able to place in mixed-mode/renderer-only
mode the cursor view into the cursor plane (if one is available).
This patch adds a further check to skip plane assignment when disabling
overlay support (when we switch to renderer-only mode), when drivers do
not have atomic-modeset or it has been disabled intentionally.

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.

Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common

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"

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.

If configless context is supported, we can skip choosing the "base" config
completely as it will never be used.

Replace a direct call to egl_choose_config() with a higher level function
gl_renderer_get_egl_config(). This will make follow-up work easier when
attribute lists will be generated inside gl_renderer_get_egl_config() instead
of passed in as is.
We explicitly replace visual_id with drm_formats, because that is what they
really are. Only the DRM backend passes in other than NULL/0, and if other
backends start caring about the actual pixel format, drm_format is the lingua
franca.

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 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

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.
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.

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
sharing is enabled. In such cases the protected content must
be censored to ensure that it is not recorded along with unprotected
content. This is a required only when the surface protection is in
enforced mode.

The member disable_planes of weston_output signifies the recording

the counter. These functions can then be used to do processing, before

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.

Fixes: 4b6e73d617 ("libweston: Add support to set content-protection for a weston_surface")
This was caused by weston_wm_handle_xfixes_selection_notify() calling
weston_seat_set_selection() with a NULL source, apparently only
sometimes when closing an Xwayland window.
Although we already supported minor version 2 of the explicit sync
protocol, we couldn't advertise it previously, since it was not in any
released version of wayland-protocols. With the release of
wayland-protocols 1.18, which includes minor version 2 of this protocol,
and the recent update in weston to require 1.18, we can now safely
advertise minor version 2.
