weston: support clone mode on DRM-frontend Add a new output section key "same-as" for configuring clone mode. An output marked "same-as" another output will be configured identically to the other output. The current implementation supports only CRTC sharing for clone mode. Independent CRTC clone mode cannot be supported until output layout logic is moved from libweston into the frontend and libweston's damage tracking issues stemming from overlapping outputs are solved. Quite a lot of infrastructure is needed to properly configure clone mode. The implemented logic allows easy addition of independent CRTC clone mode once libweston supports it. The idea is that wet_layoutput is the item to be laid out and all weston_outputs a wet_layoutput contains show exactly the same area of the desktop. The configuration logic attempts to automatically fall back to creating more weston_outputs when all heads do not work under the same weston_output. For now, the fallback path ends with an error message. Enabling a weston_output is bit complicated, because one needs to first collect all relevant heads, try to attach them all to the weston_output, and then back up head by head until enabling the weston_output succeeds. A new weston_output is created for the left-over heads and the process is repeated. CRTC-sharing clone mode is the most efficient clone mode, offering synchronized scanout timings, but it is not always supported by hardware. v10: - rebased trivial conflicts in man page - switch to gitlab issue URL v9: - replace weston_compositor_set_heads_changed_cb() with weston_compositor_add_heads_changed_listener() - remove workaround in simple_head_enable() v6: - Add man-page note about cms-colord. - Don't create an output just to turn it off.

weston: migrate DRM to head-based output API Migrate the DRM frontend to use the simple head-based output configurator, maintaining the exact same features and semantics as before. This is an intermediate step. It is unoptimal to create a weston_output just to turn it off, but the libweston implementation and the DRM backend require it for now. In the future, the DRM frontend will get its own configurator that does not create useless weston_outputs and supports clone mode by attaching multiple heads to the same weston_output. Clone mode is not yet supported by libweston/DRM. Until we remove the need to create a weston_output just to turn it "off", that is, disable it, we will hit simple_head_enable() for heads we have already disabled. As long as the DRM-backend conversion to the head-based API is not complete, attempting to create an output for a head again would lead to a crash. This problem does not exist right now, but it will after the patch "compositor-drm: start migration to head-based output API". Therefore, check if the head we are about to process is already attached, and do nothing if so. DRM outputs set to "off" are the only ones legitimately hitting this condition. This is the last frontend migrated, wet_set_pending_output_handler() is deleted as dead code. v9: - Add the workaround in simple_head_enable().

weston: support clone mode on DRM-frontend Add a new output section key "same-as" for configuring clone mode. An output marked "same-as" another output will be configured identically to the other output. The current implementation supports only CRTC sharing for clone mode. Independent CRTC clone mode cannot be supported until output layout logic is moved from libweston into the frontend and libweston's damage tracking issues stemming from overlapping outputs are solved. Quite a lot of infrastructure is needed to properly configure clone mode. The implemented logic allows easy addition of independent CRTC clone mode once libweston supports it. The idea is that wet_layoutput is the item to be laid out and all weston_outputs a wet_layoutput contains show exactly the same area of the desktop. The configuration logic attempts to automatically fall back to creating more weston_outputs when all heads do not work under the same weston_output. For now, the fallback path ends with an error message. Enabling a weston_output is bit complicated, because one needs to first collect all relevant heads, try to attach them all to the weston_output, and then back up head by head until enabling the weston_output succeeds. A new weston_output is created for the left-over heads and the process is repeated. CRTC-sharing clone mode is the most efficient clone mode, offering synchronized scanout timings, but it is not always supported by hardware. v10: - rebased trivial conflicts in man page - switch to gitlab issue URL v9: - replace weston_compositor_set_heads_changed_cb() with weston_compositor_add_heads_changed_listener() - remove workaround in simple_head_enable() v6: - Add man-page note about cms-colord. - Don't create an output just to turn it off.

weston: migrate DRM to head-based output API Migrate the DRM frontend to use the simple head-based output configurator, maintaining the exact same features and semantics as before. This is an intermediate step. It is unoptimal to create a weston_output just to turn it off, but the libweston implementation and the DRM backend require it for now. In the future, the DRM frontend will get its own configurator that does not create useless weston_outputs and supports clone mode by attaching multiple heads to the same weston_output. Clone mode is not yet supported by libweston/DRM. Until we remove the need to create a weston_output just to turn it "off", that is, disable it, we will hit simple_head_enable() for heads we have already disabled. As long as the DRM-backend conversion to the head-based API is not complete, attempting to create an output for a head again would lead to a crash. This problem does not exist right now, but it will after the patch "compositor-drm: start migration to head-based output API". Therefore, check if the head we are about to process is already attached, and do nothing if so. DRM outputs set to "off" are the only ones legitimately hitting this condition. This is the last frontend migrated, wet_set_pending_output_handler() is deleted as dead code. v9: - Add the workaround in simple_head_enable().

An output marked "same-as" another output will be configured identically to the other output. The current implementation supports only CRTC sharing for clone mode.

drm: port the drm backend to the new init api Preparing for libweston and for the separation of the code base into libweston vs. weston the compositor, we must remove all uses weston_config structures from the backends.

compositor-drm: pageflip timeout implementation Weston will not repaint until previous update has been acked by a pageflip event coming from the drm driver. However, some buggy drivers won’t return those events or will stop sending them at some point and Weston output repaints will completely freeze. To ease developers’ task in testing their drivers, this patch makes compositor-drm use a timer to detect cases where those pageflip events stop coming. This timeout implementation is software only and includes basic features usually found in a watchdog. We simply exit Weston gracefully with a log message and an exit code when the timout is reached. The timeout value can be set via weston.ini by adding a pageflip-timeout=<MILLISECONDS> entry under [core] section. Setting it to 0 disables the timeout feature. v2: - Made sure we would get both the pageflip and the vblank events before stopping the timer. - Reordered the error and success cases in drm_output_pageflip_timer_create() to be more in line with the rest of the code. v3: - Reordered (de)arming of the timer with the code around it to avoid it being rearmed before the current dearming. - Return the proper value for the dispatcher in the pageflip_timeout callback. - Also display the output name in case the timer fires. v4: - Reordered a forgotten timer rearming after its drmModePageFlip().

weston: support clone mode on DRM-frontend Add a new output section key "same-as" for configuring clone mode. An output marked "same-as" another output will be configured identically to the other output. The current implementation supports only CRTC sharing for clone mode. Independent CRTC clone mode cannot be supported until output layout logic is moved from libweston into the frontend and libweston's damage tracking issues stemming from overlapping outputs are solved. Quite a lot of infrastructure is needed to properly configure clone mode. The implemented logic allows easy addition of independent CRTC clone mode once libweston supports it. The idea is that wet_layoutput is the item to be laid out and all weston_outputs a wet_layoutput contains show exactly the same area of the desktop. The configuration logic attempts to automatically fall back to creating more weston_outputs when all heads do not work under the same weston_output. For now, the fallback path ends with an error message. Enabling a weston_output is bit complicated, because one needs to first collect all relevant heads, try to attach them all to the weston_output, and then back up head by head until enabling the weston_output succeeds. A new weston_output is created for the left-over heads and the process is repeated. CRTC-sharing clone mode is the most efficient clone mode, offering synchronized scanout timings, but it is not always supported by hardware. v10: - rebased trivial conflicts in man page - switch to gitlab issue URL v9: - replace weston_compositor_set_heads_changed_cb() with weston_compositor_add_heads_changed_listener() - remove workaround in simple_head_enable() v6: - Add man-page note about cms-colord. - Don't create an output just to turn it off.

weston: migrate DRM to head-based output API Migrate the DRM frontend to use the simple head-based output configurator, maintaining the exact same features and semantics as before. This is an intermediate step. It is unoptimal to create a weston_output just to turn it off, but the libweston implementation and the DRM backend require it for now. In the future, the DRM frontend will get its own configurator that does not create useless weston_outputs and supports clone mode by attaching multiple heads to the same weston_output. Clone mode is not yet supported by libweston/DRM. Until we remove the need to create a weston_output just to turn it "off", that is, disable it, we will hit simple_head_enable() for heads we have already disabled. As long as the DRM-backend conversion to the head-based API is not complete, attempting to create an output for a head again would lead to a crash. This problem does not exist right now, but it will after the patch "compositor-drm: start migration to head-based output API". Therefore, check if the head we are about to process is already attached, and do nothing if so. DRM outputs set to "off" are the only ones legitimately hitting this condition. This is the last frontend migrated, wet_set_pending_output_handler() is deleted as dead code. v9: - Add the workaround in simple_head_enable().

weston: Port headless backend to new output handling API This is a complete port of the headless backend that uses the recently added output handling API for output configuration. - Output can be configured at runtime by passing the necessary configuration parameters, which can be filled in manually, obtained from the configuration file or obtained from the command line using previously added functionality. It is required that the scale and transform values are set using the previously added functionality. - Output can be created at runtime using the output API. The output creation only creates a pending output, which needs to be configured the same way as mentioned above. After everything has been set, output needs to be enabled manually using weston_output_enable(). Same as before, a single output is created at runtime using the default configuration or a configuration parsed from the command line. The no-outputs functionality is also preserved, which means that no output will be created initially, but more outputs can be added at runtime using the output API. New feature: This patch also adds, as a bonus of using shared functionality, support for setting options for outputs created by this backend in the weston config file in addition to setting them from the command line. v2: - Fix wet_configure_windowed_output_from_config() usage. - Call headless_output_disable() explicitly from headless_output_destroy(). v3: - Add scale support to output width and height. - Use scaled values in calls to various functions which require width and height. - Disallow calling headless_output_configure more than once. - Remove unneeded checks for output->name == NULL as that has been disallowed. - Use weston_compositor_add_pending_output(). - Bump weston_headless_backend_config version to 2.

weston: Port headless backend to new output handling API This is a complete port of the headless backend that uses the recently added output handling API for output configuration. - Output can be configured at runtime by passing the necessary configuration parameters, which can be filled in manually, obtained from the configuration file or obtained from the command line using previously added functionality. It is required that the scale and transform values are set using the previously added functionality. - Output can be created at runtime using the output API. The output creation only creates a pending output, which needs to be configured the same way as mentioned above. After everything has been set, output needs to be enabled manually using weston_output_enable(). Same as before, a single output is created at runtime using the default configuration or a configuration parsed from the command line. The no-outputs functionality is also preserved, which means that no output will be created initially, but more outputs can be added at runtime using the output API. New feature: This patch also adds, as a bonus of using shared functionality, support for setting options for outputs created by this backend in the weston config file in addition to setting them from the command line. v2: - Fix wet_configure_windowed_output_from_config() usage. - Call headless_output_disable() explicitly from headless_output_destroy(). v3: - Add scale support to output width and height. - Use scaled values in calls to various functions which require width and height. - Disallow calling headless_output_configure more than once. - Remove unneeded checks for output->name == NULL as that has been disallowed. - Use weston_compositor_add_pending_output(). - Bump weston_headless_backend_config version to 2.

weston: Port headless backend to new output handling API This is a complete port of the headless backend that uses the recently added output handling API for output configuration. - Output can be configured at runtime by passing the necessary configuration parameters, which can be filled in manually, obtained from the configuration file or obtained from the command line using previously added functionality. It is required that the scale and transform values are set using the previously added functionality. - Output can be created at runtime using the output API. The output creation only creates a pending output, which needs to be configured the same way as mentioned above. After everything has been set, output needs to be enabled manually using weston_output_enable(). Same as before, a single output is created at runtime using the default configuration or a configuration parsed from the command line. The no-outputs functionality is also preserved, which means that no output will be created initially, but more outputs can be added at runtime using the output API. New feature: This patch also adds, as a bonus of using shared functionality, support for setting options for outputs created by this backend in the weston config file in addition to setting them from the command line. v2: - Fix wet_configure_windowed_output_from_config() usage. - Call headless_output_disable() explicitly from headless_output_destroy(). v3: - Add scale support to output width and height. - Use scaled values in calls to various functions which require width and height. - Disallow calling headless_output_configure more than once. - Remove unneeded checks for output->name == NULL as that has been disallowed. - Use weston_compositor_add_pending_output(). - Bump weston_headless_backend_config version to 2.

drm: port the drm backend to the new init api Preparing for libweston and for the separation of the code base into libweston vs. weston the compositor, we must remove all uses weston_config structures from the backends. We have decided that all option and config input happens in the compositor (main.c), and configuration is passed in for the backends as structs. Most other backends have already converted, and this patch converts the DRM-backend to the libweston-style init API. The libweston-style init API includes a header for each backend (here compositor-drm.h) defining the configuration interface. The compositor (main.c) prepares a configuration struct to be passed through libweston core to the backend during initialization. A complication with the DRM-backend is that outputs can be hotplugged, and their configuration needs to be fetched from the compositor (main.c). For this, the config struct contains a callback member. The output configuration API is subject to change later, this is just a temporary API to get libweston forward. As weston_compositor's user_data was not previously used for anything, and the output configuration callback needs data, the user_data is set to the 'config' pointer. This pointer is only used in drm_configure_output() in main.c.

weston: support clone mode on DRM-frontend Add a new output section key "same-as" for configuring clone mode. An output marked "same-as" another output will be configured identically to the other output. The current implementation supports only CRTC sharing for clone mode. Independent CRTC clone mode cannot be supported until output layout logic is moved from libweston into the frontend and libweston's damage tracking issues stemming from overlapping outputs are solved. Quite a lot of infrastructure is needed to properly configure clone mode. The implemented logic allows easy addition of independent CRTC clone mode once libweston supports it. The idea is that wet_layoutput is the item to be laid out and all weston_outputs a wet_layoutput contains show exactly the same area of the desktop. The configuration logic attempts to automatically fall back to creating more weston_outputs when all heads do not work under the same weston_output. For now, the fallback path ends with an error message. Enabling a weston_output is bit complicated, because one needs to first collect all relevant heads, try to attach them all to the weston_output, and then back up head by head until enabling the weston_output succeeds. A new weston_output is created for the left-over heads and the process is repeated. CRTC-sharing clone mode is the most efficient clone mode, offering synchronized scanout timings, but it is not always supported by hardware. v10: - rebased trivial conflicts in man page - switch to gitlab issue URL v9: - replace weston_compositor_set_heads_changed_cb() with weston_compositor_add_heads_changed_listener() - remove workaround in simple_head_enable() v6: - Add man-page note about cms-colord. - Don't create an output just to turn it off.
