2020-09-07drm/vkms: Add support for writebackRodrigo Siqueira
This patch implements the necessary functions to add writeback support for vkms. This feature is useful for testing compositors if you don't have hardware with writeback support. Change in V4 (Emil and Melissa): - Move signal completion above drm_crtc_add_crc_entry() - Make writeback always available - Use appropriate namespace - Drop fb check in vkms_wb_atomic_commit - Make vkms_set_composer visible for writeback code - Enable composer operation on prepare_job and disable it on cleanup_job - Drop extra space at the end of the file - Rebase Change in V3 (Daniel): - If writeback is enabled, compose everything into the writeback buffer instead of CRC private buffer - Guarantees that the CRC will match exactly what we have in the writeback buffer. Change in V2: - Rework signal completion (Brian) - Integrates writeback with active_planes (Daniel) - Compose cursor (Daniel) Signed-off-by: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Reviewed-by: Liviu Dudau <liviu.dudau@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200830142000.146706-4-rodrigosiqueiramelo@gmail.com
2020-04-02drm/vkms: Use simple encoderThomas Zimmermann
The vkms driver uses an empty implementation for its encoder. Replace the code with the generic simple encoder.

2019-07-12drm/vkms: Avoid assigning 0 for possible_crtcRodrigo Siqueira
When vkms invoke drm_universal_plane_init(), it sets 0 for possible_crtcs parameter which means that planes can't be attached to any CRTC. It currently works due to some safeguard in the drm_crtc file; however, it is possible to identify the problem by trying to append a second connector. This patch fixes this issue by modifying vkms_plane_init() to accept an index parameter which makes the code a little bit more flexible and avoid set zero to possible_crtcs.

2019-06-06drm/vkms: Remove useless call to drm_connector_register/unregister()Rodrigo Siqueira
The function vkms_output_init() is invoked during the module initialization, and it handles the creation/configuration of the vkms essential elements (e.g., connectors, encoder, etc). Among the initializations, this function tries to initialize a connector and register it by calling drm_connector_register(). However, inside the drm_connector_register(), at the beginning of this function there is the following validation: if (!connector->dev->registered) return 0; In this sense, invoke drm_connector_register() after initializing the connector has no effect because the register field is false. The connector register happens when drm_dev_register() is invoked; the same issue exists with drm_connector_unregister(). Therefore, this commit removes the unnecessary call to drm_connector_register() and drm_connector_unregister().

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

This commit adds the essential infrastructure for around CRTCs which is composed of: a new data struct for output data information, a function for creating planes, and a simple encoder attached to the connector. Finally, due to the introduction of a new initialization function, connectors were moved from vkms_drv.c to vkms_display.c.
