2019-06-16output: remove wlr_output_impl.transformSimon Ser
The backend doesn't need to handle transform changes, since everything is done in software. In fact, all of the implementations were all identical and just set the transform. We could add support for hardware transforms, but: - This would require a different field (something like hardware_transform) - Not all combinations are possible because there often are hardware limitations - The Wayland protocol isn't ready for this (in particular xdg-output, see [1]) This belongs to a different patch series anyway.

This is fixed on amdgpu, so we don't need this anymore.

2019-06-02drm: legacy: issue a NULL modeset on disableRouven Czerwinski
The DRM subsystem needs a NULL modeset for connectors which disappear from the system to disable the hardware pipes, otherwise the pixels get rendered but are sent nowhere. The atomic backend does the equivalent by removing the properties and issuing a commit. Fixes #1706
2019-04-23output: rename needs_commit to needs_frameSimon Ser
This new name makes more sense, since it is a request from the backend to get a new frame. In the future a commit may not convey a new frame.
2019-04-23output: refactor backend APISimon Ser
This updates the backend part of the output API. This is mostly renaming: make_current becomes attach_render and swap_buffers becomes commit. This also fixes the RDP backend to support NULL damage.
2019-04-22Fix missing headers when building without X11Alyssa Ross
The deleted includes are redundant, because other headers will include the necessary files. Additionally, they cause build failures, because including EGL/egl.h or EGL/eglext.h directly, instead of through wlr/render/egl.h or wlr/render/interface.h, will mean that MESA_EGL_NO_X11_HEADERS will not have been defined, and so the EGL headers will attempt to pull in unnecessary X11 headers that may not exist on the system. For the headers produced by glgen.sh, the includes couldn't simply be deleted, because no other header would include the EGL headers. Neither wlr/render/egl.h or wlr/render/interface.h felt appropriate to include, so I opted instead to copy the MESA_EGL_NO_X11_HEADERS definition before the EGL includes.

2019-03-05backend/drm: Don't fail on failing to find overlay formatScott Anderson
Some hardware exists which doesn't support XRGB/ARGB overlays, and we aren't even using overlay planes, so don't fail on trying to find a format.

2019-02-19backend/drm: fix modeset on drm fd resumeBrian Ashworth
On DRM resume, such as switching back to a TTY, the output needs to be modeset to the current mode. However, wlr_output_set_mode will return early when attempting to set the mode to the current mode. This just steps around wlr_output_set_mode and calls drm_connector_set_mode directly.

2019-02-14drm: do not modeset to current modeBrian Ashworth
There is no point in modesetting an output to a mode that it is already set to. Modesetting will cause the output to briefly flicker which is undesirable for a noop. This returns early in `drm_connector_set_mode` when attempting to modeset to the current mode.
2019-02-04Allow cursor render surface to be used as fbVincent Vanlaer
In order for a surface to be used as a cursor plane framebuffer, it appears that requiring the buffer to be linear is sufficient. GBM_BO_USE_SCANOUT is added in case GBM_BO_USE_LINEAR isn't sufficient on untested hardware. Fixes #1323 Removed wlr_drm_plane.cursor_bo as it does not serve any purpose anymore. Relevant analysis (taken from the PR description): While trying to implement a fix for #1323, I found that when exporting the rendered surface into a DMA-BUF and reimporting it with `GBM_BO_USE_CURSOR`, the resulting object does not appear to be valid. After some digging (turning on drm-kms debugging and switching to legacy mode), I managed to extract the following error: ``` [drm:__setplane_check.isra.1 [drm]] Invalid pixel format AR24 little-endian (0x34325241), modifier 0x100000000000001 ``` The format itself refers to ARGB8888 which is the same format as `renderer->gbm_format` used in master to create the cursor bo. However, using `gbm_bo_create` with `GBM_BO_USE_CURSOR` results in a modifier of 0. A modifier of zero represents a linear buffer while the modifier of the surface that is rendered to is `I915_FORMAT_MOD_X_TILED` (see https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/include/uapi/drm/drm_fourcc.h?h=v4.20.6#n263). In order to fix this mismatch in modifier, I added the `GBM_BO_USE_LINEAR` to the render surface and everything started to work just fine. I wondered however, whether the export and import is really necessary. I then decided to test if the back buffer of the render surface works as well, and at least on my hardware (Intel HD 530 and Intel UHD 620) it does. This is the patch in this PR and this requires no exporting and importing. I have to note that I cheated in order to import DMA_BUFs into a cursor bo when doing the first tests, since on import the Intel drivers check that the cursor is 64x64. This is strange since cursor sizes other than 64x64 have been around for quite some time now (https://lists.freedesktop.org/archives/mesa-commit/2014-June/050268.html). Removing this check made everything work fine. I later (while writing this PR) found out that `__DRI_IMAGE_USE_CURSOR` (to which `GBM_BO_USE_CURSOR` translates) has been deprecated in mesa (https://gitlab.freedesktop.org/mesa/mesa/blob/master/include/GL/internal/dri_interface.h#L1296), which makes me wonder what the usecase of `GBM_BO_USE_CURSOR` is. The reason we never encountered this is that when specifying `GBM_BO_USE_WRITE`, a dumb buffer is created trough DRM and the usage flag never reaches the Intel driver directly. The relevant code is in https://gitlab.freedesktop.org/mesa/mesa/blob/master/src/gbm/backends/dri/gbm_dri.c#L1011-1089 . From this it seems that as long as the size, format and modifiers are right, any surface can be used as a cursor.

2019-01-29backend/drm: fix GBM format mismatchemersion
We create the EGL config with GBM_FORMAT_ARGB8888, but then initialize GBM BOs with GBM_FORMAT_XRGB8888. This mismatch confuses Mesa. Instead, we can always use GBM_FORMAT_ARGB8888, and use DRM_FORMAT_XRGB8888 when calling drmModeAddFB2. Fixes https://github.com/swaywm/wlroots/issues/1438
2019-01-19backend/drm: fix state for outputs loosing their CRTCemersion
When there aren't enough CRTCs for all outputs, we try to move a CRTC from a disabled output to an enabled one. When this happens, the old output's state wasn't changed, so the compositor thought it was still enabled and rendering. This commit marks the old output as WLR_DRM_CONN_NEEDS_MODESET and sets its current mode to NULL.
2018-12-23backend/drm: get physical size from libdrmemersion
Values from libdrm are likely more reliable than raw values from the EDID. We were already using values from libdrm, but they were overwritten by parse_edid. See drm.c: wlr_conn->output.phys_width = drm_conn->mmWidth; wlr_conn->output.phys_height = drm_conn->mmHeight;

2018-12-09backend/drm: fix disappeared output indicesemersion
This commit changes `scan_drm_connectors` to add new outputs to the end of the list. That way, it's easier to understand what's going on with indices. When we need to destroy outputs, we now walk the list in reverse order. This ensures indices remain correct while iterating and removing items from the list. We now also make outputs without a CRTC disappear (those are in WLR_DRM_CONN_NEEDS_MODESET state).

backend/drm: fix frame scheduling on secondary GPUs
2018-10-29backend/drm: fix frame scheduling on secondary GPUsemersion
There was a missing copy_drm_surface_mgpu call in drm_connector_schedule_frame so we asked for a pageflip with an unknown BO, resulting in ENOENT. Additionally, this commit makes schedule_frame return a bool indicating failures. This allows schedule_frame_handle_idle_timer to only set frame_pending to true if a frame has been successfully scheduled. Thus, if a pageflip fails, rendering won't be blocked forever anymore. In case a pageflip is already pending, true is returned because a frame has already been scheduled and will be sent sometime soon.
2018-10-28backend/drm: add WLR_DRM_NO_ATOMIC_GAMMA env variableemersion

2018-10-09output: remove idle_frame event source when destroying outputemersion
This prevents the idle event to be activated on a destroyed output. This also makes the backend responsible for free-ing modes, as it is the one allocating them and adding them to the list. Note that the DRM backend (the only one using modes) already frees them.
