Isaac Freund fb1f613510 scene: add primary output to wlr_scene_surface
This allows compositors to avoid sending multiple frame done events
to a surface that is rendered on multiple outputs at once. This may
also be used in the same way for presentation feedback.

Simon Ser 36a2b19485 output: introduce wlr_output_set_name
wlroots picks names for all outputs, but it might be desirable for
compositor to override it.

For instance, Sway will use a headless output as a fallback in
case no outputs are connected. Sway wants to clearly label the
fallback output as such and label "real" headless outputs starting
from HEADLESS-1.

Simon Ser c50c4fc5cc linux-dmabuf-v1: add per-surface feedback 2021-12-07 15:18:19 +01:00
Simon Ser 1d8340754b linux-dmabuf-v1: implement v4
Implement a basic version of linux-dmabuf-unstable-v1 version 4.
Only default hints are implemented.

The new wlr_linux_dmabuf_feedback_v1 data structure will allow
compositors to define their own custom hints in the future. This
data structure makes it easy to describe feedback metadata.

It's converted to a "compiled" form suitable for marshalling over
the Wayland socket via feedback_compile.

Simon Ser f016eca97c output: add wlr_output_event_commit.buffer
This allows output commit listeners to access the newly committed

Simon Ser 7201aae3d6 render/drm-format-set: add wlr_drm_format_set_intersect
This intersects two DRM format sets. This is useful for implementing
DMA-BUF feedback in compositors, see e.g. the Sway PR [1].

Simon Ser 1bf9676e87 render/egl: improve modifier support detection
Support for EXT_image_dma_buf_import_modifiers doesn't necessarily
indicate support for modifiers. For instance, Mesa will advertise
EXT_image_dma_buf_import_modifiers for all drivers. This is a trick
to allow EGL clients to enumerate supported formats (something
EXT_image_dma_buf_import is missing). For more information, see [1].

Add a new wlr_egl.has_modifiers flag which indicates whether
modifiers are supported. It's set to true if any
eglQueryDmaBufModifiersEXT query returned a non-empty list.

Use that flag to figure out whether the buffer modifier should be
passed to the EGL implementation on import.

Simon Ser 051d1ce90e render/egl: add wlr_egl_create_with_context
This allows creating a wlr_egl from an already-existing EGL display
and context. This is useful to allow compositors to choose the exact
EGL initialization parameters.

Simon Ser ba974a4e9f scene: add wlr_scene_get_scene_output
This allows getting a wlr_scene_output from a wlr_output. Since an
output can only be added once to a scene-graph there's no ambiguity.

This is useful for compositors using wlr_scene_attach_output_layout:
the output layout integration automatically creates a scene-graph
output for each wlr_output added to the layout.

Simon Ser 697a1cd0f5 output: add wlr_output_get_primary_formats
This allows compositors to get primary formats without manually
calling wlr_output_impl.get_primary_formats.

For example, the Sway patch for linux-dmabuf feedback [1] needs
this.

Simon Ser 585a908a01 scene: add wlr_scene_xdg_surface_create
This allows compositors to easily add an xdg_surface to the
scene-graph while retaining the ability to unconstraint popups
and decide their final position.

Compositors can handle new popups with the wlr_xdg_shell.new_surface
event, get the parent scene-graph node via wlr_xdg_popup.parent.data,
create a new scene-graph node via wlr_scene_xdg_surface_tree_create,
and unconstraint the popup if they want to.

Simon Ser b234edcf58 backend/headless: drop wlr_headless_backend_create_with_renderer
The headless backend no longer needs a parent renderer: it no longer
needs to return it in wlr_backend_impl.get_renderer, nor does it
need to return its DRM FD in wlr_backend_impl.get_drm_fd. Drop this
function altogether since it now behaves exactly like
wlr_headless_backend_create.

Simon Ser f29abe4c77 backend/headless: stop picking a DRM FD
Sometimes the headless backend is used standalone with the Pixman
renderer, sometimes it's used together with another backend which
has already picked a DRM FD. In both of these cases it doesn't make
sense to pick a DRM FD.

Broadly speaking the headless backend doesn't really care which DRM
device is used for the buffers it receives. So it doesn't really
make sense to tie it to a particular DRM device.

Let the backend users (e.g. wlr_renderer_autocreate) open an arbitrary
DRM FD as needed instead.

Simon Ser 1d9c1bcea6 input-device: remove wlr_input_device.link
This field's ownership is unclear: it's in wlr_input_device, but
it's not managed by the common code, it's up to each individual
backend to use it and clean it up.

Since this is a backend implementation detail, move it to the
backend-specific structs.

Simon Ser 3b93da70a0 backend/wayland: report parent presentation clock
There's no guarantee that the parent Wayland compositor uses
CLOCK_MONOTONIC for reporting presentation timestamps, they could
be using e.g. CLOCK_MONOTONIC_RAW or another system-specific clock.

Forward the value via wlr_backend_impl.get_presentation_clock.

Simon Ser 3d73b899ff linux-dmabuf-v1: hide wlr_linux_buffer_params_v1
The parameters are used when the client is in the process of
building a buffer. There's no reason why this internal
implementation detail should be exposed in our public header.

Manuel Stoeckl e879d566bb output: Add function to set preferred render format
This change introduces new double buffered state to the wlr_output,
corresponding to the buffer format to render to.

The format being rendered to does not control the bit depth of colors
being sent to the display; it does generally determine the format with
which screenshot data is provided. The DRM backend _may_ sent higher
bit depths if the render format depth is increased, but hardware and
other limitations may apply.

Manuel Stoeckl 7508f87fcb output: lift up output format fallback logic

Simon Ser a04cfca4da Remove support for DMA-BUF flags
They are never used in practice, which makes all of our flag
handling effectively dead code. Also, APIs such as KMS don't
provide a good way to deal with the flags. Let's just fail the
DMA-BUF import when clients provide flags.

Isaac Freund ab16861e86 text-input: fix type of send_preedit_string() args
The protocol uses a signed integer here, which is also what the
wlr_input_method_v2_preedit_string struct provides to compositors from
the input method protocol. Sway currently just passes those int32_t
values directly to this function leading to an implicit conversion.

Ronan Pigott e2aff8a9b0 xdg-activation-v1: add data field and emit token destroy events
The data field is useful to track metadata about a token. The destroy

Ronan Pigott 6ad0f819e2 xdg-activation-v1: enable compositors to request their own tokens

without participating in the xdg-activation procedure as a wayland

This enables the compositor itself to behave as a launcher
application.

Simon Ser 0817c52a21 backend/drm: get rid of BO handle table
The BO handle table exists to avoid double-closing a BO handle,
which aren't reference-counted by the kernel. But if we can
guarantee that there is only ever a single ref for each BO handle,
then we don't need the BO handle table anymore.

This is possible if we create the handle right before the ADDFB2
IOCTL, and close the handle right after. The handles are very
short-lived and we don't need to track their lifetime.

Because of multi-planar FBs, we need to be a bit careful: some
FB planes might share the same handle. But with a small check, it's
easy to avoid double-closing the same handle (which wouldn't be a
big deal anyways).

There's one gotcha though: drmModeSetCursor2 takes a BO handle as
input. Saving the handles until drmModeSetCursor2 time would require
us to track BO handle lifetimes, so we wouldn't be able to get rid
of the BO handle table. As a workaround, use drmModeGetFB to turn the
FB ID back to a BO handle, call drmModeSetCursor2 and then immediately
close the BO handle. The overhead should be minimal since these IOCTLs
are pretty cheap.
