2018-09-28backend/drm: don't free connector immediatelyemersion
When a pageflip is pending, we'll get a DRM event for the connector in the future. We don't want to free the connector immediately otherwise we'll use-after-free in the pageflip handler. This commit adds a new state, "DISAPPEARED". This asks the pageflip handler to destroy the output after it's done pageflipping.

2018-09-15backend/drm: steal CRTCs from disabled outputsemersion
This commit allows outputs that need a CRTC to steal it from user-disabled outputs. Note that in the case there are enough CRTCs, disabled outputs don't loose it (so there's no modeset and plane initialization needed after DPMS). CRTC allocation still prefers to keep the old configuration, even if that means allocating an extra CRTC to a disabled output. CRTC reallocation now happen when enabling/disabling an output as well as when trying to modeset. When enabling an output without a CRTC, we realloc to try to steal a CRTC from a disabled output (that doesn't really need the CRTC). When disabling an output, we try to give our CRTC to an output that needs one. Modesetting is similar to enabling. A new DRM connector field has been added: `desired_enabled`. Outputs without CRTCs get automatically disabled. This field keeps track of the state desired by the user, allowing to automatically re-enable outputs when a CRTC becomes free. This required some changes to the allocation algorithm. Previously, the algorithm tried to keep the previous configuration even if a new configuration with a better score was possible (it only changed configuration when the old one didn't work anymore). This is now changed and the old configuration (still preferred) is only retained without considering new possibilities when it's perfect (all outputs have CRTCs). User-disabled outputs now have `possible_crtcs` set to 0, meaning they can only retain a previous CRTC (not acquire a new one). The allocation algorithm has been updated to do not bump the score when assigning a CRTC to a disabled output.

2018-09-07Implement device type discovery using ioctl callssghctoma
This commit implements device type discovery by calling two ioctls (DRM_IOCTL_VERSION and EVIOCGVERSION) on the device. These iocts are specific to drm and input devices respectively, therefore we can determine the device type based on which one returns an error.

2018-09-04backend/drm: better hotplug handlingemersion
This commit handles better situations in which the number of connected outputs is greater than the number of available CRTCs. It'll enable as many outputs as possible, and transfer CRTCs to outputs that need one on unplug. This changes CRTC and plane reallocation to happen after scanning DRM connectors instead of on modeset. This cleanups CRTCs and planes on unplug to allow them to be re-used for other outputs. On modeset, if an output doesn't have a CRTC, the desired mode is saved and used later when the output gains a CRTC. Future work includes giving priority to enabled outputs over disabled ones for CRTC allocation. This requires the compositor to know about all outputs (even outputs without CRTCs) to properly modeset outputs enabled in the compositor config file and disable outputs disabled in the config file.
2018-09-02Activate last active VT after compositor exitsghctoma
The VT the compositor was started from was not activated after exiting the compositor, which resulted in arriving on a blank VT. This commit fixes that by introducing a new field in direct_session struct that stores the last active VT so that it can be activated in direct_session_destroy.

2018-09-02backend/drm: emit new_output after scanning connectorsemersion
This prevents receiving modesetting requests from the compositor while we don't have the whole picture (ie. while we haven't yet scanned all connectors). This also makes connectors without CRTCs disabled (they can't be enabled yet even if some CRTCs are free'd -- this is future work).

A few pedantic changes and unused variables (1-4), and genuine bugs (5, 6).

2018-08-30Fix that major(st_rdev) have no meaning on FreeBSDsghctoma
The major device number does not indicate the device type on FreeBSD, and AFAIK the only way to differentiate between DRM, input, and other devices is checking the fd path. This commit implements that. The drmDropmaster and drmSetmaster calls are necessary, because the implicit drop (that should occur when the DRM fd is closed) seems not to be working in some scenarios (e.g. if you have a tmux session running - maybe the fd is retained somehow by tmux?). This is a problem, because once you exit the compositor, you can't start it (or any other program that wants to be DRM master) again until you close all your tmux sessions.

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.
