2021-06-17backend/session: use DRM_PRIMARY_MINOR_NAMESimon Ser
Instead of hardcoding the string "card", use DRM_PRIMARY_MINOR_NAME. Some systems may use another prefix, e.g. OpenBSD uses "drm" instead.
2021-06-17backend/session: use drmIsKMSSimon Ser
This moves the magic incantation into libdrm and is clearer. See [1] for details. While at it, fixup the doc comment and improve logging. [1]: https://gitlab.freedesktop.org/mesa/drm/-/commit/523b3658aa8efa746417e916c987de23740ce313
2021-04-27backend/session: add wlr_device.events.removeSimon Ser
2021-04-18backend/session: Close remaining devices on destroyKenny Levinsen
2021-04-18backend/session: Close fd in wlr_session_close_fileKenny Levinsen
This was lost in the session_impl removal refactor.
2021-04-14backend/session: Remove session_implKenny Levinsen
libseat provides all session functionality, so there is no longer need for a session backend abstraction. The libseat device ID, seat handle and event loop handle are moved to the main wlr_session and wlr_device structs.
2021-04-14backend/session: Remove noop backendKenny Levinsen
This is instead delegated to libseat.
2021-04-14backend/session: Remove direct backendKenny Levinsen
This is instead delegated to libseat.
2021-04-14backend/session: Make libseat mandatoryKenny Levinsen
2021-04-11backend/session: Remove logind backendKenny Levinsen
This is instead delegated to libseat.
2021-02-28backend/session: fix KMS device filteringSimon Ser
As explained in [1], user-space should perform a drmModeGetResources call to figure out whether a device supports KMS. [1]: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/127
2021-02-05Make implementation function lists static constManuel Stoeckl
This requires a change to the type of `struct wlr_tablet` and `wlr_tablet_init` signature, both of which are part of the unstable API.
2021-01-04backend/session: allow wlr_session_find_gpus to return an errorSimon Ser
Sometimes wlr_session_find_gpus will encounter an error. This is different from finding zero GPUs. On error, wlr_session_find_gpus already returns -1. However, this is casted to size_t, so callers uncorrectly assume this is a success. Instead, make wlr_session_find_gpus return a ssize_t and allow callers to handle the error accordingly.
2020-11-19backend/session: add a timeout waiting for GPUsSimon Ser
If a GPU doesn't show up in 10s, bail out and return zero GPUs.
2020-11-19backend/session: replace session_signal with events.activeSimon Ser
This is more idiomatic wlroots API. The new name makes it clear that the signal is emitted when wlr_session.active changes.
2020-11-19backend/session: wait for DRM device if none foundSimon Ser
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 Closes: https://github.com/swaywm/wlroots/issues/2093
2020-11-19backend/session: introduce wlr_session.events.add_drm_cardSimon Ser
This is triggered when a new DRM card is added. An easy way to test this patch is `modprobe vkms`.
2020-11-19backend/session: filter udev events by sysnameSimon Ser
We're only interested in card devices. The loop over wlr_session.devices would take care of ignoring non-card events, but a future patch will listen to udev "add" events as well.
2020-11-19backend/session: operate on wlr_deviceSimon Ser
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.
2020-11-19backend/session: don't return FD on failure in open_fileSimon Ser
When wlr_session_open_file fails, don't return the FD, otherwise the caller will think the call succeeded.
2020-08-24session: Add libseat backendKenny Levinsen
2020-02-17backend/session: allow GPU enumeration on FreeBSDJan Beich

2019-08-12backend/session: non-void function should return a valueAntonin Décimo
With assertions disabled, it should make sense to return NULL.
2019-07-27Remove all wayland-server.h includesSimon Ser
The documentation for wayland-server.h says: > Use of this header file is discouraged. Prefer including > wayland-server-core.h instead, which does not include the server protocol > header and as such only defines the library PI, excluding the deprecated API > below. Replacing wayland-server.h with wayland-server-core.h allows us to drop the WL_HIDE_DEPRECATED declaration.
2019-03-02backend/session: add noop sessionemersion
This is the first step towards being able to run via DRM leasing and on render nodes. Test with: export WLR_BACKENDS=drm export WLR_SESSION=noop export WLR_DRM_DEVICES=/dev/dri/renderD128
2018-11-12Use #if instead of #ifdef for wlroots config dataemersion
This prevents some annoying issues when e.g. not including wlr/config.h or making a typo in the guard name.
2018-09-18Add support for WLR_SESSION env variablerandom human
Valid values are "logind"/"systemd" and "direct". If WLR_SESSION is set, only its value is potentially tried; it will not try any other option.
2018-08-27Init the new destroy signals added by #1200Alexander Bakker
2018-08-26Add destroy signals to types that are destroyed by wl_display_destroyAlexander Bakker
2018-08-08session: load GPU devices even if they have zero crtcs/connectors/encodersIlia Bozhinov
On some systems (most notably laptops with two GPUs) there are GPUs that don't have attached outputs. However, we still want to load those GPUs because they could still be used by the compositor for rendering.
