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

calls gles2's destroy_buffer, which calls glDeleteFramebuffers.

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].

Patrick Steinhardt fa05d3cde6 session: Don't refuse unprivileged creation of "direct" backend
When starting a compositor that's using the "direct" session backend,
wlroots needs to handle calls to `drmSetMaster()` and `drmDropMaster()`.
As both calls used to require `CAP_SYS_ADMIN`, wlroots thus simply
refused starting in case the process doesn't enjoy evelated privileges.

Permission rules have changed since linux.git commit 45bc3d26c95a (drm:
rework SET_MASTER and DROP_MASTER perm handling, 2020-03-19). As a
result, starting with Linux v5.8, both ioctls will now also succeed if
the process is currently or has been the DRM master. And as the first
process to open render nodes will become the DRM master automatically,
this effectively means that process elevation is not strictly required
in all setups anymore.

So let's drop the `geteuid() != 0` permission check to allow those new
rules to do their magic.

Simon Ser bf93d2e67c output: rename impl->rollback to rollback_render
The output backend API is now mostly state-less thanks to the atomic
hooks (commit and test). There is one exception though: attach_render.
This function makes the rendering context current. However sometimes the
compositor might decide not to render after attach_render (e.g. when
there's nothing new to render to the back buffer). Thus
wlr_output_rollback has been introduced to revert the pending state.

Because the output backend API is mostly state-less, the only thing
wlr_output_impl.rollback needs to do is revert the current rendering
context. Rename the function to rollback_render to make this clear. Add
a check in the common wlr_output code to only call rollback_render when
attach_buffer has been previously called.

On the long term, we'll be able to remove attach_render and
rollback_render together.

Simon Ser e77c046cf9 backend/drm: fix stack overflow in dealloc_crtc
Call drm_crtc_commit directly instead of calling drm_connector_set_mode.
This restores the previous behaviour where conn_enable was called [1].

Tudor Brindus dc13bb827d util: fix and move `get_current_time_msec` into a util file
This commit makes `get_current_time_msec` correctly return milliseconds
as opposed to microseconds. It also considers the value of `tv_sec`, so
we don't lose occasionally go back in time by one second. Finally, the
function is moved into `util/time.cc` so that it can be reused elsewhere
without having to consider these pitfalls.

Simon Ser 019fe8bb7e backend/wayland: fix spurious eglSwapBuffers failures
This was introduced in [1]. However after reverting that PR I still
can't reproduce the bug the PR aimed to fix [2].

Since there's no good explanation why we would need to swap buffers
before resizing, let's just revert the PR.
