From 3750e78c72da3c35292dcf531ebe3062faaa33bc Mon Sep 17 00:00:00 2001 From: Bruce Wang Date: Fri, 5 Oct 2018 17:04:01 -0400 Subject: drm/msm: Cut dpu_kms hooks from msm_pm_suspend/resume Removes the traces of the non-atomic helper calls in msm_pm_suspend/resume since we just deleted those functions (see patch 1). Also removes the drm_kms_helper_poll_disable/enable calls, since the DRM_CONNECTOR_POLL_CONNECT flag is never set so periodic polling doesn't happen anyways. v2: reorganized patch order v3: made error checks less severe Reviewed-by: Sean Paul Signed-off-by: Bruce Wang Signed-off-by: Sean Paul Signed-off-by: Rob Clark --- drivers/gpu/drm/msm/msm_drv.c | 27 ++++++++++++--------------- drivers/gpu/drm/msm/msm_kms.h | 3 --- 2 files changed, 12 insertions(+), 18 deletions(-) diff --git a/drivers/gpu/drm/msm/msm_drv.c b/drivers/gpu/drm/msm/msm_drv.c index 5e758d95751a..aa145d6f6469 100644 --- a/drivers/gpu/drm/msm/msm_drv.c +++ b/drivers/gpu/drm/msm/msm_drv.c @@ -1070,18 +1070,15 @@ static int msm_pm_suspend(struct device *dev) { struct drm_device *ddev = dev_get_drvdata(dev); struct msm_drm_private *priv = ddev->dev_private; - struct msm_kms *kms = priv->kms; - - /* TODO: Use atomic helper suspend/resume */ - if (kms && kms->funcs && kms->funcs->pm_suspend) - return kms->funcs->pm_suspend(dev); - drm_kms_helper_poll_disable(ddev); + if (WARN_ON(priv->pm_state)) + drm_atomic_state_put(priv->pm_state); priv->pm_state = drm_atomic_helper_suspend(ddev); if (IS_ERR(priv->pm_state)) { - drm_kms_helper_poll_enable(ddev); - return PTR_ERR(priv->pm_state); + int ret = PTR_ERR(priv->pm_state); + DRM_ERROR("Failed to suspend dpu, %d\n", ret); + return ret; } return 0; @@ -1091,16 +1088,16 @@ static int msm_pm_resume(struct device *dev) { struct drm_device *ddev = dev_get_drvdata(dev); struct msm_drm_private *priv = ddev->dev_private; - struct msm_kms *kms = priv->kms; + int ret; - /* TODO: Use atomic helper suspend/resume */ - if (kms && kms->funcs && kms->funcs->pm_resume) - return kms->funcs->pm_resume(dev); + if (WARN_ON(!priv->pm_state)) + return -ENOENT; - drm_atomic_helper_resume(ddev, priv->pm_state); - drm_kms_helper_poll_enable(ddev); + ret = drm_atomic_helper_resume(ddev, priv->pm_state); + if (!ret) + priv->pm_state = NULL; - return 0; + return ret; } #endif diff --git a/drivers/gpu/drm/msm/msm_kms.h b/drivers/gpu/drm/msm/msm_kms.h index fd88cebb6adb..2b81b43a4bab 100644 --- a/drivers/gpu/drm/msm/msm_kms.h +++ b/drivers/gpu/drm/msm/msm_kms.h @@ -67,9 +67,6 @@ struct msm_kms_funcs { void (*set_encoder_mode)(struct msm_kms *kms, struct drm_encoder *encoder, bool cmd_mode); - /* pm suspend/resume hooks */ - int (*pm_suspend)(struct device *dev); - int (*pm_resume)(struct device *dev); /* cleanup: */ void (*destroy)(struct msm_kms *kms); #ifdef CONFIG_DEBUG_FS -- cgit v1.2.3
