This allows compositors to integrate with the wlroots GLES2
renderer, if they need to perform custom GL rendering.
|
|
These formats require EXT_texture_norm16, which in turn needs OpenGL
ES 3.1. The EXT_texture_norm16 extension does not support passing
gl_internalformat = GL_RGBA to glTexImage2D, as can be done for
formats available in OpenGL ES 2.0, so this commit adds a field to
wlr_gles2_pixel_format to provide a more specific internalformat
parameter to glTexImage2D.
|
|
Added the implement of wlr_texture_is_vk.
Fixes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3419

Ensures there is no field left to its previous undefined value after
calling an init function.

This removes an artificial limitation in form of an assert that disallowed the
creation of textures while the renderer is rendering.
A consumer might run its own rendering pipeline and after start of the renderer
still want to create textures for internal usage.
|
|
This can be useful to figure out why a required feature is missing,
e.g. as in [1].
We check VK_EXT_physical_device_drm availability after printing
the driver name.

commit 44e8451cd93e ("render/gles2: hide shm formats without GL
support") added the is_gles2_pixel_format_supported() function to
render/gles2/pixel_format.c, whose stated purpose is to "check whether
the renderer has the needed GL extensions to read a given pixel format."
It then used that function to filter the pixel formats returned by
get_gles2_shm_formats().
The result of this change is that RGB formats are no longer reported for
GL drivers that don't implement EXT_read_format_bgra, even when those
formats are supported for rendering (which they have to be for
wlr_gles2_renderer_create() to succeed). This is a pretty clear
regression, since wlr_renderer_init_wl_shm() fails when either of
WL_SHM_FORMAT_ARGB8888 or WL_SHM_FORMAT_XRGB8888 are missing.
To fix the regression, change is_gles2_pixel_format_supported() to
accept all pixel formats that support rendering, regardless of whether
we can read them or not, and move the check for EXT_read_format_bgra
back into gles2_read_pixels(). (There's already a check for this
extension in gles2_preferred_read_format(), so we're not breaking any
abstraction that wasn't already broken.)
Tested on the NVIDIA 495.46 proprietary driver, which doesn't support
EXT_read_format_bgra.

This allows compositors to initialize wl_shm without initializing
other globals like linux-dmabuf.
|
|
This intersects two DRM format sets. This is useful for implementing
DMA-BUF feedback in compositors, see e.g. the Sway PR [1].

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.

The backends and allocators use INVALID, but the renderer uses
LINEAR. Running a compositor with WLR_RENDERER=pixman results in:
00:00:00.744 [types/output/render.c:59] Failed to pick primary buffer format for output 'WL-1'
|
|
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.
|
|
The next commit will split extension lookup and context
initialization.
|
|
This was used to make the intersection of INVALID and LINEAR result
in LINEAR. We can now just require LINEAR to be in both lists.

This env var allows to override the DRM node used by the GLES2 and
Vulkan renderers. It's especially useful to select a DRM node when
running with the headless backend.
References: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/2656
|
|
If the backend doesn't have a DRM FD, fallback to the renderer's.
This accomodates for the situation where the headless backend hasn't
picked a DRM FD in particular, but the renderer has picked one.
|
|
If the backend hasn't picked a DRM FD but supports DMA-BUF, pick
an arbitrary render node. This will allow removing the DRM device
selection logic from the headless backend.

This ends up being a horrible global load:

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)

This suppresses the output filename printed to stdout. Errors and
warnings should still be printed to stderr as usual.

A wlroots user can easily get confused and think that `cap` refers to
wlroots buffer capabilities, not array capacity.
|
|
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.

For `required` to disable search the value needs to be of `feature` type.
Checking `gles2` via `in` keyword returns a `bool` but `required: false`
makes the dependency optional instead of disabled.

calloc is moved to right before egl is called to avoid requiring to free()

There's no pkg-config file we can check for sadly, so check
vulkan/vulkan.h as a fallback.

This new renderer is implemented with the existing wlr_renderer API
(which is known to be sub-optimal for some operations). It's not
used by default, but users can opt-in by setting WLR_RENDERER=vulkan.
The renderer depends on VK_EXT_image_drm_format_modifier and
VK_EXT_physical_device_drm.

This allows us to obtain a new DRM file description without relying
on filesystem permissions.
|
|
If we aren't trying to create a dumb buffer allocator, and if the
DRM device has a render node (ie, not a split render/display SoC),
then we can use the render node instead of the primary node. This
should allow wlroots to run under seatd when the current user
doesn't have the permission to open primary nodes (logind has a
quirk to allow physically logged in users to open primary nodes).

This allows callers to specify the operations they'll perform on
the returned data pointer. The motivations for this are:
- The upcoming Linux MAP_NOSIGBUS flag may only be usable on
read-only mappings.
- gbm_bo_map with GBM_BO_TRANSFER_READ hurts performance.
