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.

2018-09-04backend/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.

I failed to see this issue with Valgrind because of the +1.
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).
2018-09-01backend/drm: allow disabling outputs in NEEDS_MODESET stateemersion
This correctly frees CRTCs when disabling outputs without setting a mode.
2018-08-29Use legacy modesetting for gamma controlDrew DeVault
It doesn't look like there's any motion on a fix from the AMDGPU side, and using the legacy interface for this isn't so bad.

These aren't used anymore and crashes when the gbm_bo tries to get destroyed (e.g. on hotplug).
2018-08-04Fix hardware cursor on secondary GPUScott Anderson
Create rendering resources on parent GPU, so that we can sample the passed in texture properly. The cursor buffer needs to remain on the same GPU.
2018-08-03multi-gpu: do not flip screens on secondary GPUMariusz Bialonczyk
All screens on secondary GPU in multiple GPU configurations was flipped 180. The flipped screens was always on secondary card (the primary card was always correct). Tested on nouveau with: WLR_DRM_DEVICES=/dev/dri/card1:/dev/dri/card2 WLR_DRM_DEVICES=/dev/dri/card2:/dev/dri/card1 The commit is fixing this problem. Now all screens are "normal".
2018-08-03multi-backend: do not expose internal renderersMariusz Bialonczyk
backend_get_renderer() is now returning the renderer of the primary GPU, instead of its own renderer, since that's the thing which actually does all of the "real" rendering wlr_multi_backend_add() is now adding all subbackends (otherwise only one GPU is handled). credits: @ascent12

2018-05-25backends: implement custom EGL and renderer initializationIlia Bozhinov
Compositors now have more control over how the backend creates its renderer. Currently all backends create an EGL/GLES2 renderer, so the necessary attributes for creating the context are passed to a user-provided callback function. It is responsible for initializing provided wlr_egl and to return a renderer. On fail, return 0. Fixes #987

2018-05-01output: always use hardware cursors if availableemersion
This changes the `wlr_output_impl.set_cursor` function to take a `wlr_texture` instead of a byte buffer. This simplifies the DRM and Wayland backends since they were creating textures from the byte buffer anyway. With this commit, performance should be improved when moving the cursor since outputs don't need to be re-rendered anymore.
