backend/drm: print DRM device name when scanning connectors 2020-12-17 20:50:19 +01:00

backend/drm: add wlr_drm_backend.name
Save the DRM device name in a wlr_drm_backend field, so that we can
easily use it for logging purposes.

backend/drm: remove nouveau workaround
The workaround is broken because drm_fb_acquire doesn't leave the EGL
context current anymore. We'll need to re-introduce it.

Simon Ser 0dcdb5e7a1 backend/x11: fix DRI3 formats not used
We queried DRI3 formats, but we weren't using them. Because of a typo,
only render formats were used.

Simon Ser 0aa2ba0c03 backend/headless: select the rendering device ourselves
Backends will eventually stop creating their renderer. To prepare for
this, stop using EGL_PLATFORM_SURFACELESS_MESA in the headless renderer.
Pick a render node using libdrm.

The new allocator/renderer creation logic looks very much like what will
end up in common code.

backend/drm: add wlr_drm_connector.backend
This allows the DRM code to have direct access to the wlr_drm_backend
without having to go through an upcast via get_drm_backend_from_backend.

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 038285d496 backend/wayland: stop rendering black frame on init
Instead of rendering a black frame, schedule a frame event to ask the
compositor to render a proper frame.
2020-12-13 12:16:28 +01:00
Simon Ser 768131e488 output: stop assuming a frame is pending in init
- The DRM backend initially doesn't have a frame scheduled initially.
  However the compositor is expected to set a mode to start the
  rendering loop (frame_pending is set to true in drm_crtc_pageflip).
- The headless and X11 backends have a timer to schedule frames, so they
  ignore this hint completely.
- The Wayland backend renders a fake frame to start the rendering loop.
  It's the only case where a frame is pending on init, move the
  assumption there.

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 8bc5a92a98 Revert "backend/drm: stop force-probing connectors"
This reverts commit 713c1661b7.

It turns out we do need to force-probe on startup and on hotplug [1].
This is unfortunate, but that's just how the uAPI works. Fixing this
would require patching the kernel.

Simon Ser 713c1661b7 backend/drm: stop force-probing connectors
After discussing with Pekka and Daniel on #dri-devel, we concluded [1]
that user-space shouldn't need to force-probe connectors. Force-probing
can take some time, so using drmModeGetConnectorCurrent can result in
faster start-up.

Users can manually trigger a force-probe if necessary:

    echo detect | sudo tee /sys/class/drm/card0-DP-1/status

Or just by running a tool like drm_info.

A similar change has been submitted to Weston [2].

Simon Ser fbf11a41e1 backend/session: wait for DRM device if none found
Wait for a DRM device if none is found in wlr_session_find_gpus. This
can happen if the compositor is loaded before the display kernel driver.

This supersedes the logind CanGraphical property.

To test, e.g. with i915 and sway:

    rmmod -f i915
    sway &
    modprobe i915

Simon Ser 44a4792fd8 backend/session: operate on wlr_device
Instead of operating on FDs in {open,close}_device, operate on
wlr_devices. This avoids the device lookup in wlr_session and allows
callers to have access to wlr_device fields.

For now, we use it to remove wlr_session_signal_add and replace it with
a more idiomatic wlr_session.events.change field. In the future, other
events will be added.
