2019-02-20T09:25:49+00:00

commit 7fd56e0260a22c0cfaf9adb94a2427b76e239dd0 upstream. Fixes license inconsistent related to the VKMS driver and remove the redundant boilerplate comment.

drm/vkms: Fix connector leak at the module removal

2018-07-28T19:09:39+00:00

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.

drm: drop _mode_ from drm_mode_connector_attach_encoder

2018-07-13T16:40:27+00:00

Again to align with the usual prefix of just drm_connector_. Again done with sed + manual fixup for indent issues. Reviewed-by: Sean Paul Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20180709084016.23750-7-daniel.vetter@ffwll.ch

drm/vkms: Add framebuffer and plane helpers

2018-07-12T14:24:05+00:00

This patch appends the minimum helpers related to framebuffer and plane to make vkms minimally usable. Changes since V1: - None Changes since V2: - Squash "Add plane helper struct" and "Add helper for framebuffer create" Changes since V3: Daniel Vetter: - Remove atomic_check from plane helper Signed-off-by: Rodrigo Siqueira Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/d37807da7d3b39444b4c9abb149fe3c518d07c61.1531402095.git.rodrigosiqueiramelo@gmail.com

drm/vkms: Add vblank events simulated by hrtimers

2018-07-12T06:48:48+00:00

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 Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/7709bba40782ec06332d57fff337797b272581fc.1531359228.git.rodrigosiqueiramelo@gmail.com

drm/vkms: Add connectors helpers

2018-07-12T06:48:42+00:00

This patch adds the struct drm_connector_helper_funcs with some necessary hooks. Additionally, it also adds some missing hooks at drm_connector_funcs.

drm/vkms: Add dumb operations

2018-07-12T06:47:44+00:00

VKMS currently does not handle dumb data, and as a consequence, it does not provide mechanisms for handling gem. This commit adds the necessary support for gem object/handler and the dumb functions.

drm/vkms: Add basic CRTC initialization

2018-07-05T12:46:23+00:00

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.
