From 9f4c97a236d35b9fe45168a979adb5e1522c0968 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 8 Dec 2015 18:41:54 +0200 Subject: [PATCH] drm: Add plane->name and use it in debug prints MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Show a sensible name for the plane in debug mesages. The driver may supply its own name, otherwise the core genrates the name ("plane-0", "plane-1" etc.). v2: kstrdup() the name passed by the caller (Jani) v3: Generate a default name if the driver doesn't supply one Signed-off-by: Ville Syrjälä Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1449592922-5545-7-git-send-email-ville.syrjala@linux.intel.com --- drivers/gpu/drm/drm_atomic.c | 12 ++++++------ drivers/gpu/drm/drm_atomic_helper.c | 4 ++-- drivers/gpu/drm/drm_crtc.c | 30 +++++++++++++++++++++++++++++ include/drm/drm_crtc.h | 2 ++ 4 files changed, 40 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/drm_atomic.c b/drivers/gpu/drm/drm_atomic.c index feb66895e48c..6a21e5c378c1 100644 --- a/drivers/gpu/drm/drm_atomic.c +++ b/drivers/gpu/drm/drm_atomic.c @@ -549,8 +549,8 @@ drm_atomic_get_plane_state(struct drm_atomic_state *state, state->planes[index] = plane; plane_state->state = state; - DRM_DEBUG_ATOMIC("Added [PLANE:%d] %p state to %p\n", - plane->base.id, plane_state, state); + DRM_DEBUG_ATOMIC("Added [PLANE:%d:%s] %p state to %p\n", + plane->base.id, plane->name, plane_state, state); if (plane_state->crtc) { struct drm_crtc_state *crtc_state; @@ -770,8 +770,8 @@ static int drm_atomic_plane_check(struct drm_plane *plane, } if (plane_switching_crtc(state->state, plane, state)) { - DRM_DEBUG_ATOMIC("[PLANE:%d] switching CRTC directly\n", - plane->base.id); + DRM_DEBUG_ATOMIC("[PLANE:%d:%s] switching CRTC directly\n", + plane->base.id, plane->name); return -EINVAL; } @@ -1248,8 +1248,8 @@ int drm_atomic_check_only(struct drm_atomic_state *state) for_each_plane_in_state(state, plane, plane_state, i) { ret = drm_atomic_plane_check(plane, plane_state); if (ret) { - DRM_DEBUG_ATOMIC("[PLANE:%d] atomic core check failed\n", - plane->base.id); + DRM_DEBUG_ATOMIC("[PLANE:%d:%s] atomic core check failed\n", + plane->base.id, plane->name); return ret; } } diff --git a/drivers/gpu/drm/drm_atomic_helper.c b/drivers/gpu/drm/drm_atomic_helper.c index 6ba3fe5639e4..63f925b75357 100644 --- a/drivers/gpu/drm/drm_atomic_helper.c +++ b/drivers/gpu/drm/drm_atomic_helper.c @@ -545,8 +545,8 @@ drm_atomic_helper_check_planes(struct drm_device *dev, ret = funcs->atomic_check(plane, plane_state); if (ret) { - DRM_DEBUG_ATOMIC("[PLANE:%d] atomic driver check failed\n", - plane->base.id); + DRM_DEBUG_ATOMIC("[PLANE:%d:%s] atomic driver check failed\n", + plane->base.id, plane->name); return ret; } } diff --git a/drivers/gpu/drm/drm_crtc.c b/drivers/gpu/drm/drm_crtc.c index efa57e8a99b5..62fa95fa5471 100644 --- a/drivers/gpu/drm/drm_crtc.c +++ b/drivers/gpu/drm/drm_crtc.c @@ -1181,6 +1181,18 @@ void drm_encoder_cleanup(struct drm_encoder *encoder) } EXPORT_SYMBOL(drm_encoder_cleanup); +static unsigned int drm_num_planes(struct drm_device *dev) +{ + unsigned int num = 0; + struct drm_plane *tmp; + + drm_for_each_plane(tmp, dev) { + num++; + } + + return num; +} + /** * drm_universal_plane_init - Initialize a new universal plane object * @dev: DRM device @@ -1224,6 +1236,22 @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, return -ENOMEM; } + if (name) { + va_list ap; + + va_start(ap, name); + plane->name = kvasprintf(GFP_KERNEL, name, ap); + va_end(ap); + } else { + plane->name = kasprintf(GFP_KERNEL, "plane-%d", + drm_num_planes(dev)); + } + if (!plane->name) { + kfree(plane->format_types); + drm_mode_object_put(dev, &plane->base); + return -ENOMEM; + } + memcpy(plane->format_types, formats, format_count * sizeof(uint32_t)); plane->format_count = format_count; plane->possible_crtcs = possible_crtcs; @@ -1314,6 +1342,8 @@ void drm_plane_cleanup(struct drm_plane *plane) if (plane->state && plane->funcs->atomic_destroy_state) plane->funcs->atomic_destroy_state(plane, plane->state); + kfree(plane->name); + memset(plane, 0, sizeof(*plane)); } EXPORT_SYMBOL(drm_plane_cleanup); diff --git a/include/drm/drm_crtc.h b/include/drm/drm_crtc.h index 4bea0a1151bc..c2f98ba2bb98 100644 --- a/include/drm/drm_crtc.h +++ b/include/drm/drm_crtc.h @@ -1496,6 +1496,8 @@ struct drm_plane { struct drm_device *dev; struct list_head head; + char *name; + struct drm_modeset_lock mutex; struct drm_mode_object base; -- 2.30.2
