drm/vkms: Add support for writeback 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

drm/vkms: Introduce basic VKMS driver This patch introduces Virtual Kernel Mode-Setting (VKMS) driver. It creates a very basic kms driver with 1 crtc/encoder/connector/plane. VKMS driver would be useful for testing, or for running X (or similar) on headless machines and be able to still use the GPU. Thus it enables a virtual display without the need for hardware display capability.
