Simon Ser c6b009ef85 render: introduce shared memory allocator
It allocates in local main memory via shm_open, and provides a FD
to allow sharing with other processes.

This is suitable for software rendering under the Wayland and X11
backends.

Simon Ser 004cf887b7 render/gles2: prevent imported DMA-BUF textures from being mutated
The compositor shouldn't write to client buffers if the client
attaches a DMA-BUF to a wl_surface, then attaches a shm buffer.
Make gles2_texture_write_pixels return an error to prevent this
from happening.

Roman Gilg b36af22c94 backend: move get_drm_fd to public interface
The get_drm_fd was made available in an internal header with a53ab146f. Move it
now to the public header so consumers opting in to the unstable interfaces can
make use of it.

Stephan Hilb 9f012cac2f drm: check for PRIME support
PRIME support for buffer sharing has become mandatory since the renderer
rewrite. Make sure we check for the appropriate capabilities in backend,
allocator and renderer.

See also #2819.

Simon Ser 9ecfa4343a render: remove wlr_texture_to_dmabuf
This is unused in wlroots, and the use-cases for compositors are
pretty niche since they can access the original DMA-BUF via the
wlr_buffer.

Simon Ser 1cdef8da57 render: drop wlr_renderer_blit_dmabuf
It can be replaced with wlr_renderer_bind_buffer. blit_dmabuf is
broken as-is (dies on an assertion).

example code. On EGL_PLATFORM_GBM_KHR platform, we should be check the

Simon Ser b514d4afe2 render/egl: stop relying on platform for high priority
All backends use the GBM platform. We can't use it to figure out
whether the DRM backend is used anymore.

Let's just try to always request a high-priority EGL context. Failing
to do so is not fatal.

Simon Ser b89bcffea4 render/egl, backend/wayland: add workaround for split render/display setups
Split render/display setups have two separate devices: one display-only
with a primary node, and one render-only with a render node. However
in these cases the EGL implementation and the Wayland compositor will
advertise the display device instead of the render device [1]. The EGL
implementation will magically open the render device when the display
device is passed in.

So just pass the display device as if it were a render device. Maybe in
the future Mesa will advertise the render device instead and we'll be
able to remove this workaround.

Compute only the transform matrix in the output. The projection matrix

render/gles2: remove YUV blocklist
Mesa provides YUV shaders, and can import multi-planar YUV DMA-BUFs
as a single EGLImage. Remove the arbitrary limitation.

If the driver doesn't support importing YUV as a single EGLImage,
the import will fail and the result will be the same anyways.

Quantum 975d14b799 render/wlr_texture: clamp texture coordinates to edge by default
Clamping texture coordinates prevents OpenGL from blending the left and
right edge (or top and bottom edge) when scaling textures with GL_LINEAR
filtering. This prevents visual artifacts like swaywm/sway#5809.

Per discussion on IRC, this behaviour is made default. Compositors that want
the wrapping behaviour (e.g. for tiled patterns) can override this by doing:

    struct wlr_gles2_texture_attribs attribs;
    wlr_gles2_texture_get_attribs(texture, &attribs);

    glBindTexture(attribs.target, attribs.tex);
    glTexParameteri(attribs.target, GL_TEXTURE_WRAP_S, GL_REPEAT);
    glTexParameteri(attribs.target, GL_TEXTURE_WRAP_T, GL_REPEAT);
    glBindTexture(attribs.target, 0);

Simon Zeni 6becc69ec9 render/egl: fail to create wlr_egl on software renderer
The creation of `wlr_egl` will fail is the device extension
EGL_MESA_device_software is defined. The creation process is allowed to
continue only if the environment variable `WLR_RENDERER_ALLOW_SOFTWARE`
is defined to the value 1.

Simon Ser 4f06ce2550 render/gbm_allocator: avoid drmPrimeHandleToFD
Some drivers (e.g. nouveau) need to do some book-keeping when exporting
a BO handle to a DMA-BUF [1]. Using drmPrimeHandleToFD directly hides
the export from the user-space drivers and causes some ref'counting
issues.

So we can't properly handle BOs with a different handle for each plane
until [2] lands.

Simon Ser bf86110fc5 render/gbm_allocator: set modifier to INVALID if implicit
When gbm_bo_create is used and the GBM implementation does support
modifiers, gbm_bo_get_modifier may return something other than
DRM_FORMAT_MOD_INVALID. This can cause issues with the rest of the
stack (e.g. EGL or KMS) in case these don't support modifiers.

Instead, force the modifier to INVALID, to make sure no one uses
modifiers.

Simon Ser b5cefada92 render/gbm_allocator: export to DMA-BUF on init
Instead of lazily exporting BOs to DMA-BUFs, do it on init. This is

that work.

This is preparatory work for the next commit.

Simon Ser afdf4dc890 render/gles2: make EGL context current in bind_buffer
Instead of requiring callers to manually make the EGL context current
before binding a buffer and unsetting it after unbinding a buffer, do
it inside wlr_renderer_bind_buffer.

This hides renderer-specific implementation details inside the
wlr_renderer interface. Non-GLES2 renderers may not use EGL.
This removes all EGL dependencies from the backends.
