2018-08-03drm/vkms: Subclass plane stateHaneen Mohammed2-3/+55
Subclass plane state struct to enable storing driver's private state. This patch only adds the base drm_plane_state struct and the atomic functions that handle it.

2018-07-28drm/vkms: Fix connector leak at the module removalRodrigo Siqueira1-0/+1
Currently, vkms shows an error message if the following steps occur: (1) load vkms, (2) perform any specific operation in the vkms (e.g., run an IGT test), and (3) unload the module. The following error message emerges: [drm:drm_mode_config_cleanup [drm]] *ERROR* connector Virtual-1 leaked! This commit fixes this error by calling drm_atomic_helper_shutdown() before drm_mode_config_cleanup, which turns off the whole display pipeline and remove a reference related to any connector.

2018-07-12drm/vkms: Add vblank events simulated by hrtimersRodrigo Siqueira3-0/+119
This commit adds regular vblank events simulated through hrtimers, which is a feature required by VKMS to mimic real hardware. Additionally, all the vblank event send after pageflip is kept in the atomic_flush function. Changes since V1: - Compute the vblank timer interval per interruption Ville Syrjälä and Daniel Vetter: - Removes hardcoded vblank interval to get it from user space Changes since V2: Chris Wilson - Removes unnecessary algorithm to compute the next period Daniel Vetter: - Uses drm_calc_timestamping_constants to get the vblank interval instead of calculating it manually - Adds disable_vblank helper that turns of crtc - Simplifies implementation by using drm_crtc_arm_vblank_event - Replaces the code in atomic_begin to atomic_flush - Removes unnecessary field in vkms_output Changes since V3: Daniel Vetter: - Squash "drm/vkms: Add atomic helpers functions" into the commit that handling vblank events simulated by hrtimers Signed-off-by: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/7709bba40782ec06332d57fff337797b272581fc.1531359228.git.rodrigosiqueiramelo@gmail.com

2018-07-12drm/vkms: Add dumb operationsRodrigo Siqueira4-1/+213

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.

2018-07-05drm/vkms: Introduce basic VKMS driverHaneen Mohammed3-0/+162
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.
