I think it's a good idea to have macros to determine whether an entity exposes a V4L2 sub-device interface but it should be more robust than is_media_entity_v4l2_subdev() right now is. Incorrect result can have consequences from a pipeline start failure (due to a failure in link validation) to memory corruption as struct media_entity pointer is assumed to be a pointer to a field of another struct. How about assigning that in V4L2 sub-device / video device registration, for example?

I think it's a good idea to have macros to > determine whether an entity exposes a V4L2 sub-device interface but it > should be more robust than is_media_entity_v4l2_subdev() right now is. Hmm... Not sure what you're meaning... the V4L2 sub-device interface is actually a separate graph object (interfaces). Those macros work at the entities, not at the interface objects. > Incorrect result can have consequences from a pipeline start failure (due to > a failure in link validation) to memory corruption as struct media_entity > pointer is assumed to be a pointer to a field of another struct. Yes, an incorrect result would cause pipeline failures. > How about assigning that in V4L2 sub-device / video device registration, > for example? What do you mean? Could you give an example to make it clearer? Regards, Mauro

Those macros work at the > entities, not at the interface objects. is_media_entity_v4l2_subdev() will produce wrong results for a large part of V4L2 sub-devices with these patches applied. I checked again the original implementation, and it seems to be based only on the type as well, albeit that's a range, not a set of different functions. I suppose this will change at some point in the future: the interface indeed should not be determined by the function of the entity. At least it needs to be fixed now until the rework. I'll submit a patch for that.

Yes. As we're getting rid of ranges for subdevs, we need to change the implementation.

For devices that don't have non-V4L2 media controller nodes, this would work, but if we ever add ALSA, DVB, IIO, etc to the media controller, then we may have troubles. That's why I opted to add a macro for checking for the V4L2 subdev. This is more future-proof, as other patches may be adding other non-V4L2 types of MC entities have the potential of breaking codes like the above. > > > continue; > > subdev = media_entity_to_v4l2_subdev(entity); > > ret = v4l2_subdev_call(subdev, video, s_stream, 1); > > @@ -334,7 +334,7 @@ static int vpfe_pipeline_disable(struct vpfe_pipeline > > *pipe) > > > > while ((entity = media_entity_graph_walk_next(&graph))) { > > > > - if (media_entity_type(entity) == MEDIA_ENT_T_DEVNODE) > > + if (!is_media_entity_v4l2_subdev(entity)) > > continue; > > subdev = media_entity_to_v4l2_subdev(entity); > > ret = v4l2_subdev_call(subdev, video, s_stream, 0); > > diff --git a/drivers/staging/media/omap4iss/iss.c > > b/drivers/staging/media/omap4iss/iss.c index 40591963b42b..44b88ff3ba83 > > 100644 > > --- a/drivers/staging/media/omap4iss/iss.c > > +++ b/drivers/staging/media/omap4iss/iss.c > > @@ -397,7 +397,7 @@ static int iss_pipeline_pm_use_count(struct media_entity > > *entity) media_entity_graph_walk_start(&graph, entity); > > > > while ((entity = media_entity_graph_walk_next(&graph))) { > > - if (media_entity_type(entity) == MEDIA_ENT_T_DEVNODE) > > + if (is_media_entity_v4l2_io(entity)) > > use += entity->use_count; > > } > > > > @@ -419,7 +419,7 @@ static int iss_pipeline_pm_power_one(struct media_entity > > *entity, int change) { > > struct v4l2_subdev *subdev; > > > > - subdev = media_entity_type(entity) == MEDIA_ENT_T_V4L2_SUBDEV > > + subdev = is_media_entity_v4l2_subdev(entity) > > ? media_entity_to_v4l2_subdev(entity) : NULL; > > > > if (entity->use_count == 0 && change > 0 && subdev != NULL) { > > @@ -461,7 +461,7 @@ static int iss_pipeline_pm_power(struct media_entity > > *entity, int change) media_entity_graph_walk_start(&graph, entity); > > > > while (!ret && (entity = media_entity_graph_walk_next(&graph))) > > - if (media_entity_type(entity) != MEDIA_ENT_T_DEVNODE) > > + if (is_media_entity_v4l2_subdev(entity)) > > ret = iss_pipeline_pm_power_one(entity, change); > > > > if (!ret) > > @@ -471,7 +471,7 @@ static int iss_pipeline_pm_power(struct media_entity > > *entity, int change) > > > > while ((first = media_entity_graph_walk_next(&graph)) > > && first != entity) > > - if (media_entity_type(first) != MEDIA_ENT_T_DEVNODE) > > + if (is_media_entity_v4l2_subdev(first)) > > iss_pipeline_pm_power_one(first, -change); > > > > return ret; > > @@ -590,8 +590,7 @@ static int iss_pipeline_disable(struct iss_pipeline > > *pipe, break; > > > > pad = media_entity_remote_pad(pad); > > - if (pad == NULL || > > - media_entity_type(pad->entity) != MEDIA_ENT_T_V4L2_SUBDEV) > > + if (!pad || !is_media_entity_v4l2_subdev(pad->entity)) > > break; > > > > entity = pad->entity; > > @@ -658,8 +657,7 @@ static int iss_pipeline_enable(struct iss_pipeline > > *pipe, break; > > > > pad = media_entity_remote_pad(pad); > > - if (pad == NULL || > > - media_entity_type(pad->entity) != MEDIA_ENT_T_V4L2_SUBDEV) > > + if (!pad || !is_media_entity_v4l2_subdev(pad->entity)) > > break; > > > > entity = pad->entity; > > diff --git a/drivers/staging/media/omap4iss/iss_video.c > > b/drivers/staging/media/omap4iss/iss_video.c index > > 45a3f2d778fc..cbe5783735dc 100644 > > --- a/drivers/staging/media/omap4iss/iss_video.c > > +++ b/drivers/staging/media/omap4iss/iss_video.c > > @@ -191,8 +191,7 @@ iss_video_remote_subdev(struct iss_video *video, u32 > > *pad) > > > > remote = media_entity_remote_pad(&video->pad); > > > > - if (remote == NULL || > > - media_entity_type(remote->entity) != MEDIA_ENT_T_V4L2_SUBDEV) > > + if (!remote || !is_media_entity_v4l2_subdev(remote->entity)) > > return NULL; > > > > if (pad) > > @@ -217,7 +216,7 @@ iss_video_far_end(struct iss_video *video) > > if (entity == &video->video.entity) > > continue; > > > > - if (media_entity_type(entity) != MEDIA_ENT_T_DEVNODE) > > + if (!is_media_entity_v4l2_io(entity)) > > continue; > > > > far_end = to_iss_video(media_entity_to_video_device(entity)); >

Instead of relying on media subtype, use the new macros to detect if an entity is a subdev or an A/V DMA entity. Please note that most drivers assume that there's just AV_DMA or V4L2 subdevs. This is not true anymore, as we've added MC support for DVB, and there are plans to add support for ALSA and FB/DRM too. Ok, on the current pipelines supported by those drivers, just V4L stuff are there, but, assuming that some day a pipeline that also works with other subsystems will ever added, it is better to add explicit checks for the AV_DMA stuff.
