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 0d32118a80 output: fix modifier stripping
DRM formats with an empty modifier list are invalid. Instead of
emptying the list, reduce it to { INVALID }.

Add a check to make sure the renderer and backend support implicit
modifiers, so that we don't fallback on e.g. Vulkan.

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 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.

Rouven Czerwinski d37eb5c2ea linux-dmabuf-v1: filter out LINEAR if implicit
If only INVALID and LINEAR are valid modifiers, we need to filter out
LINEAR since Xwayland won't be able to allocate a BO with the explicit
linear modifier on hardware that does not support explicit modifiers.
The addition of LINEAR is an internal implementation detail which
simplifies the wlroots architecture for now.

Evntually Xwayland should be fixed to filter out modifiers that are not
supported by the GBM implementation, see [1]. This could be done by
querying EGL for the supported modifiers.

Simon Ser 585a908a01 scene: add wlr_scene_xdg_surface_create
This allows compositors to easily add an xdg_surface to the

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 e4f748c6e9 render/allocator: fallback to renderer DRM FD in autocreate
If the backend doesn't have a DRM FD, fallback to the renderer's.

The above output was based on just shoving it in ShaderPlayground -- I was not able to use pipeline feedback as I was unable to get RenderDoc working due to the EXT_physical_device_drm requirement.

I additionally considered using >> 1 instead of * 0.5, but AMD has dedicated modifiers to merge a * 0.5, * 2.0, etc in a single instruction. (Albeit, not taken advantage of in the code above, but might with ACO)

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.
