Simon Ser 3f7e0cf5f0 render/egl: remove surface and buffer age args from make_current
These aren't used anymore.

Simon Ser d9bbc416a6 backend/drm: re-use FBs
Instead of importing buffers to GBM and KMS at each frame, cache them
and re-use them while the wlr_buffer is alive.

This is the same as [1] and [2] but for the DRM backend.

Simon Ser 91cb0fc443 backend/drm: only keep track of local buffer
Stop keeping track of buffers on the parent GPU when multi-GPU is used.

This removes support for export_dmabuf on secondary GPUs, but renderer
v6 will bring this back by managing the swapchains in wlr_output instead
of the backends.

Simon Ser 07d75c99db render: remove EGL config and visual from wlr_renderer_autocreate
This isn't used anymore by any backend.

Some examples still provide an EGL config to wlr_egl_init, so we can't
drop it yet there.

Simon Ser 4b03bdc3ab Remove wlr_create_renderer_func_t
This callback allowed compositors to customize the EGL config used by
the renderer. However with renderer v6 EGL configs aren't used anymore.
Instead, buffers are allocated via GBM and GL FBOs are rendered to. So
customizing the EGL config is a no-op.

Simon Ser bec1e6b149 backend/drm: remove special linear case for cursor plane
We now properly mark the cursor plane's formats as linear-only, and we
now have a version of wlr_drm_format_intersect that handles the case of
linear-only formats and implicit modifiers.

We can remove the special drm_plane_init_surface flag we had for cursor
planes. This also allows us to use a non-linear layout for cursor planes
on drivers that support it.

Tested on amdgpu GFX9.

backend/drm: dup FD before wlr_gbm_allocator_create
The GBM allocator takes ownership of the DRM FD.
2020-12-15 20:50:04 +01:00
Simon Ser 93cd3a79b2 backend/drm: stop using GBM flags
gbm_bo_create_with_modifiers doesn't take GBM flags, so our
wlr_gbm_allocator interface doesn't either. We were still internally
using GBM flags in the DRM backend, leading to awkward back-and-forth
conversions.

The only flag passed to drm_plane_init_surface was GBM_BO_USE_LINEAR, so
turn that into a bool to make sure other flags can't be passed in.

Move the "force linear" logic out of init_drm_surface, because the
supplied wlr_drm_format should already contain that information.

Simon Ser e69bbfd0d6 backend/drm: unset current surface before importing
drm_fb_import_wlr may need to change the current EGL context. For
instance by calling drm_fb_clear, which calls wlr_buffer_unlock, which
may destroy a buffer if the cursor swapchain size has changed, which
calls gles2's destroy_buffer, which calls glDeleteFramebuffers.

backend/drm: use EGL_PLATFORM_GBM_KHR
This is just the vendor-agnostic define for the GBM platform. It has the
same value as EGL_PLATFORM_GBM_MESA, so should work with old drivers

Simon Ser af2f69e6c1 render/egl: unset current context after swapping buffers
After swapping buffers, it doesn't make sense to perform more rendering
operations. Unset the context to reflect this.

This commit makes it so the context is always only current between
wlr_egl_make_current and wlr_egl_swap_buffers.

This is an alternative to [1].

Simon Ser 98d949718c backend/drm: strip alpha channel if necessary
Some primary planes don't support ARGB8888, they only support XRGB8888
(for instance on older Intel hardware). The DRM backend would fail to
initialize.

When that's the case, try to allocate buffers without an alpha channel.

Scott Anderson 8da9d9679e backend/drm: introduce wlr_drm_fb
This is a type which manages gbm_surfaces and imported dmabufs in the
same place, and makes the lifetime management between the two shared. It
should lead to easier to understand code, and fewer special cases.

This also contains a fair bit of refactoring to start using this new
type.

Simon Ser 515679e4fe Refactor EGL/GL API loading
Remove glapi.sh code generation, replace it with hand-written loading
code that checks extension strings before calling eglGetProcAddress.

The GLES2 renderer still uses global state because of:

- {PUSH,POP}_GLES2_DEBUG macros
- wlr_gles2_texture_from_* taking a wlr_egl instead of the renderer

Simon Ser 6ca82087b1 backend/drm: fix segfault in init_drm_surface
When surf->gbm was previously set, we destroy it without setting it to
NULL. Later on, we only create the GBM surface if surf->gbm is NULL.
This result in a use-after-free when we start using surf->gbm.

Alyssa Ross 95b22619e0 Fix missing headers when building without X11
The deleted includes are redundant, because other headers will include
the necessary files. Additionally, they cause build failures, because
including EGL/egl.h or EGL/eglext.h directly, instead of through
wlr/render/egl.h or wlr/render/interface.h, will mean that
MESA_EGL_NO_X11_HEADERS will not have been defined, and so the EGL
headers will attempt to pull in unnecessary X11 headers that may not
exist on the system.

For the headers produced by glgen.sh, the includes couldn't simply be
deleted, because no other header would include the EGL headers. Neither
wlr/render/egl.h or wlr/render/interface.h felt appropriate to include,
so I opted instead to copy the MESA_EGL_NO_X11_HEADERS definition before
the EGL includes.

backend/drm: fix GBM format mismatch
We create the EGL config with GBM_FORMAT_ARGB8888, but then initialize GBM BOs
with GBM_FORMAT_XRGB8888. This mismatch confuses Mesa.

Instead, we can always use GBM_FORMAT_ARGB8888, and use DRM_FORMAT_XRGB8888
when calling drmModeAddFB2.
