Currently the idle_repaint_source is removed when the output is destroyed.
This covers the most common case: When a monitor is unplugged then the
corresponding DRM output is destroyed and not just disabled.
However, outputs can be explicitly disabled by the shell. In this case the
output is not removed and idle_repaint() may be called for a removed
output.
Remove the idle_repaint_source in weston_compositor_remove_output() to fix
this. And reset the variable to ensure that the source can be created
again.
Removing the source in weston_output_release() is now no longer necessary
since it calls weston_compositor_remove_output().

weston_compositor_reflow_outputs() assumes that all output are positioned from
left to right with no gaps in the same order in which they where created.
If the shell moves an output with weston_output_move() then this assumption is
no longer true. So stop reflowing the outputs in the case. The shell is now
responsible for positioning all outputs as needed.

By moving the application of view_alpha after pre-multiplication we can
simplify main() considerably.
The cost is that for straight-alpha input or color_pipeline() we might
be doing three multiplications more than before. However,
a) the cost of running color_pipeline() probably dominates anyway, and
b) to get straight-alpha input you have to use a future Wayland
extension that probably won't be advertised without color management.
So we keep the optimization for the simple case (no color management)
while potentially incurring a small cost on the heavy case (with color
management).

There is missing dependency on linux-dmabuf-unstable-v1-server-protocol.h
header file in backend-headless, backend-drm and backend-x11. That files
do not depend on that header, in fact. But by this moment they've had
that implicit dependency due to linux-dmabuf.h header.
With specific set of meson configure options the protocol header is not
generated at the right time, what causes build error in 100% cases using

"max bpc" property is meant for working around faulty sink hardware.
Normally it should be set to the maximum possible value so that the
kernel driver has full freedom to choose the link bpc without being
artificially forced to lower color precision.
The default value is 16 because that is a nice round number and more
than any link technology I've heard is using today which would be 12.
Also offer an API set the value, so that weston.ini could be used in the
next patch for sink workaround purposes.

This reverts commit 6914064066.
This is a follow-up change of b623fd2a ("drm-backend: stop parsing IN_FORMATS
blobs, use libdrm instead"). Weston now has a hard-requirement on libdrm
2.4.108, clean up remaining and unnecessary conditional code. Change 69140640

and stop including libdrm-updates.h from kms-color.c.

Before this change the drm-backend in Weston did the work of parsing DRM
blobs in order to query IN_FORMATS data, if available. This is also the
case for other DRM/KMS clients that use IN_FORMATS (i.e. X).
libdrm 2.4.108 with e641e2a6 ("xf86drm: add iterator API for DRM/KMS
IN_FORMATS blobs") introduced a dedicated API for querying IN_FORMATS data.
Bump the minimum required version to 2.4.108, stop parsing IN_FORMATS in
Weston and start using DRM iterators. In addition, remove fallback code for
libdrm <2.4.107.

This patch makes sure we have a gl_buffer_state present when using
direct-display protocol extensions (which forbids any GL imports, and
assumes a direct path with the display unit to perform a KMS import).
Without this patch we would basically have no gl_buffer_state at repaint
time because we never manged to create one, as direct-display code path
will return much early.

When color management is disabled, the fragment shader was still first
ensuring straight alpha and then immediately just going back to
pre-multiplied. This is near-impossible for a shader compiler to
optimize out, I guess because of the if-statement to handle division by
zero. Having view alpha applied in between certainly didn't make it
easier.
That causes extra fragment computations that are unnecessary. In the
issue report this was found to cause a notable performance regression.
Fix the performance regression by introducing special-case paths for
when straight alpha is not needed. This skips the unnecessary
computations.

Currently, the opaque is discarded for all transformations other than a simple
translation, because correctly transforming the opaque area is not possible in
general.
However, there is one simple case that is probably the most common one: A fully
opaque surface that is translated and scaled. In this case the opaque area is
simply the new bounding box. So set the transformed opaque area accordingly.
Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
If surface->is_opaque is set then we can assume that the whole surface is
opaque. In the trivial case (no transformation or translation only) this means
that transform.boundingbox is exactly the view area and is fully opaque. So it
can be used for transform.opaque.
This is important because damage calculation uses transform.opaque. Without
this, anything underneath a surface without an explicit opaque region but a
pixel format without alpha channel is drawn unnecessarily.
