2016-06-28[media] v4l: vsp1: lut: Initialize the mutexLaurent Pinchart
The LUT mutex isn't initialized when creating the LUT, fix it. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-28[media] v4l: vsp1: dl: Don't free fragments with interrupts disabledLaurent Pinchart
Freeing a fragment requires freeing DMA coherent memory, which can be performed with interrupts disabled as per the DMA mapping API contract. The fragments can't thus be freed synchronously when a display list is recycled. Instead, move the fragments to a garbage list and use a work queue to run the garbage collection.

2016-06-28[media] v4l: vsp1: Set entities functionsLaurent Pinchart
Initialize the function field of all subdev entities instantiated by the driver. This gets rids of multiple warnings printed by the media controller core. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-28[media] v4l: vsp1: Don't create LIF entity when the userspace API is enabledLaurent Pinchart
The LIF is only used when feeding the VSP output to the DU. The only way to do so is by controlling the VSP directly from the DU driver and disabling the VSP userspace API. There is thus no need to create a LIF entity when the userspace API is enabled, as it can't be used in that case.

2016-06-28[media] v4l: vsp1: Don't register media device when userspace API is disabledLaurent Pinchart
The media device doesn't need to be exposed to userspace when the VSP is fully controlled by the DU driver. Don't register it in that case. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-28[media] v4l: vsp1: Base link creation on availability of entitiesLaurent Pinchart
Check the entity pointer instead of the feature flag to see if the entity is available before creating related links. The two methods are currently equivalent, but will differ in the future as we implement support for ignoring some of the entities present in the hardware.

2016-06-28[media] v4l: vsp1: sru: Fix intensity control IDLaurent Pinchart
The intensity control reused the V4L2_CID_CONTRAST control ID by mistake. Fix it by using an ID from the device-specific IDs range. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-28[media] v4l: vsp1: Stop the pipeline upon the first STREAMOFFLaurent Pinchart
The device is stopped when STREAMOFF is called on the last video node in the pipeline. This results in possible memory corruption and/or crashes, as userspace could free buffers while the hardware is still writing to them, and the frame completion interrupt handler could try to access buffers that don't exist anymore. Fix this by stopping the pipeline upon the first STREAMOFF call, not the last.

2016-06-28[media] v4l: vsp1: pipe: Fix typo in commentLaurent Pinchart

2016-06-28[media] v4l: vsp1: Fix crash when resetting pipelineLaurent Pinchart
The vsp1_pipeline_reset() function loops over pipeline inputs and output and resets them. When doing so it assumes both that the pipeline has been correctly configured with an output, and that inputs are are stored in the pipe inputs array at positions 0 to num_inputs-1. Both the assumptions are incorrect. The pipeline might need to be reset after a failed attempts to configure it, without any output specified. Furthermore, inputs are stored in a positiong equal to their RPF index, possibly creating holes in the inputs array if the RPFs are not used in sequence. Fix both issues by looping over the whole inputs array and skipping unused entries, and ignoring the output when not set.

2016-06-17[media] v4l: vsp1: Group DRM RPF parameters in a structureLaurent Pinchart
The vsp1_du_atomic_update_ext() function takes 7 RPF configuration parameters, and more will likely be added later. This makes the code difficult to read and error-prone as multiple parameters have the same type. Make the API safer and easier to extend in the future by grouping all parameters in a structure. Use macro magic to ease the transition to the new function by allowing the old and new functions to be called using the same name. The macros and static inline wrapper will be removed as soon as the caller is updated.

2016-04-13[media] v4l: vsp1: Add support for the RPF alpha multiplier on Gen3Laurent Pinchart
The Gen3 RPF includes an alpha multiplier that can both multiply the alpha channel by a fixed global alpha value, and multiply the pixel components to convert the input to premultiplied alpha. As alpha premultiplication is available in the BRU for both Gen2 and Gen3 we handle it there and use the Gen3 alpha multiplier for global alpha multiplication only. This prevents conversion to premultiplied alpha if no BRU is present in the pipeline, that use case will be implemented later if needed.

2016-04-13[media] v4l: vsp1: dl: Fix race conditionsLaurent Pinchart
The vsp1_dl_list_put() function expects to be called with the display list manager lock held. This assumption is correct for calls from within the vsp1_dl.c file, but not for the external calls.

The subdev s_stream operation is abused as a generic way to setup modules at every frame. Move the code out to a new VSP1 entity configure operation. Most modules now have an empty s_stream operation that can be removed. The only exception is the WPF module that needs to perform hardware configuration when stopping the stream.
