As the firmware-kms driver -doesn't support asynchronous updates, these are synchronous, which -limits the update rate to the screen refresh rate. Xorg seems unaware -of this (or at least of the effect of this), because if the mouse is -configured with a higher update rate than the screen then continuous -mouse movement results in an increasing backlog of mouse events - -cue extreme lag. - -Add minimal support for asynchronous updates - limited to cursor -planes - to eliminate the lag. - -See: https://github.com/raspberrypi/linux/pull/4971 - https://github.com/raspberrypi/linux/issues/4988 - -Signed-off-by: Phil Elwell <phil@raspberrypi.com> ---- - drivers/gpu/drm/vc4/vc4_firmware_kms.c | 46 ++++++++++++++++++++++++++ - 1 file changed, 46 insertions(+) - ---- a/drivers/gpu/drm/vc4/vc4_firmware_kms.c -+++ b/drivers/gpu/drm/vc4/vc4_firmware_kms.c -@@ -675,6 +675,50 @@ static int vc4_plane_atomic_check(struct - return vc4_plane_to_mb(plane, &vc4_plane->mb, new_plane_state); - } - -+static void vc4_plane_atomic_async_update(struct drm_plane *plane, -+ struct drm_atomic_state *state) -+{ -+ struct drm_plane_state *new_plane_state = -+ drm_atomic_get_new_plane_state(state, plane); -+ -+ swap(plane->state->fb, new_plane_state->fb); -+ plane->state->crtc_x = new_plane_state->crtc_x; -+ plane->state->crtc_y = new_plane_state->crtc_y; -+ plane->state->crtc_w = new_plane_state->crtc_w; -+ plane->state->crtc_h = new_plane_state->crtc_h; -+ plane->state->src_x = new_plane_state->src_x; -+ plane->state->src_y = new_plane_state->src_y; -+ plane->state->src_w = new_plane_state->src_w; -+ plane->state->src_h = new_plane_state->src_h; -+ plane->state->alpha = new_plane_state->alpha; -+ plane->state->pixel_blend_mode = new_plane_state->pixel_blend_mode; -+ plane->state->rotation = new_plane_state->rotation; -+ plane->state->zpos = new_plane_state->zpos; -+ plane->state->normalized_zpos = new_plane_state->normalized_zpos; -+ plane->state->color_encoding = new_plane_state->color_encoding; -+ plane->state->color_range = new_plane_state->color_range; -+ plane->state->src = new_plane_state->src; -+ plane->state->dst = new_plane_state->dst; -+ plane->state->visible = new_plane_state->visible; -+ -+ vc4_plane_set_blank(plane, false); -+} -+ -+static int vc4_plane_atomic_async_check(struct drm_plane *plane, -+ struct drm_atomic_state *state) -+{ -+ struct drm_plane_state *new_plane_state = -+ drm_atomic_get_new_plane_state(state, plane); -+ int ret = -EINVAL; -+ -+ if (plane->type == 2 && -+ plane->state->fb && -+ new_plane_state->crtc->state->active) -+ ret = 0; -+ -+ return ret; -+} -+ - /* Called during init to allocate the plane's atomic state. */ - static void vc4_plane_reset(struct drm_plane *plane) - { -@@ -769,6 +813,8 @@ static const struct drm_plane_helper_fun - .atomic_check = vc4_plane_atomic_check, - .atomic_update = vc4_plane_atomic_update, - .atomic_disable = vc4_plane_atomic_disable, -+ .atomic_async_check = vc4_plane_atomic_async_check, -+ .atomic_async_update = vc4_plane_atomic_async_update, - }; - - static struct drm_plane *vc4_fkms_plane_init(struct drm_device *dev, |
