2021-09-30media: videobuf2: rework vb2_mem_ops APISergey Senozhatsky1-18/+19
With the new DMA API we need an extension of the videobuf2 API. Previously, videobuf2 core would set the non-coherent DMA bit in the vb2_queue dma_attr field (if user-space would pass a corresponding memory hint); the vb2 core then would pass the vb2_queue dma_attrs to the vb2 allocators. The vb2 allocator would use the queue's dma_attr and the DMA API would allocate either coherent or non-coherent memory. But we cannot do this anymore, since there is no corresponding DMA attr flag and, hence, there is no way for the allocator to become aware of what type of allocation user-space has requested. So we need to pass more context from videobuf2 core to the allocators. Fix this by changing the call_ptr_memop() macro to pass the vb2 pointer to the corresponding op callbacks.

2021-06-24media: Fix Media Controller API config checksShuah Khan1-1/+1
Smatch static checker warns that "mdev" can be null: sound/usb/media.c:287 snd_media_device_create() warn: 'mdev' can also be NULL If CONFIG_MEDIA_CONTROLLER is disabled, this file should not be included in the build. The below conditions in the sound/usb/Makefile are in place to ensure that media.c isn't included in the build. sound/usb/Makefile: snd-usb-audio-$(CONFIG_SND_USB_AUDIO_USE_MEDIA_CONTROLLER) += media.o select SND_USB_AUDIO_USE_MEDIA_CONTROLLER if MEDIA_CONTROLLER && (MEDIA_SUPPORT=y || MEDIA_SUPPORT=SND_USB_AUDIO) The following config check in include/media/media-dev-allocator.h is in place to enable the API only when CONFIG_MEDIA_CONTROLLER and CONFIG_USB are enabled. #if defined(CONFIG_MEDIA_CONTROLLER) && defined(CONFIG_USB) This check doesn't work as intended when CONFIG_USB=m. When CONFIG_USB=m, CONFIG_USB_MODULE is defined and CONFIG_USB is not. The above config check doesn't catch that CONFIG_USB is defined as a module and disables the API. This results in sound/usb enabling Media Controller specific ALSA driver code, while Media disables the Media Controller API. Fix the problem requires two changes: 1. Change the check to use IS_ENABLED to detect when CONFIG_USB is enabled as a module or static. Since CONFIG_MEDIA_CONTROLLER is a bool, leave the check unchanged to be consistent with drivers/media/Makefile. 2. Change the drivers/media/mc/Makefile to include mc-dev-allocator.o in mc-objs when CONFIG_USB is enabled.

2021-06-17media: subdev: disallow ioctl for saa6588/davinciArnd Bergmann1-0/+4
The saa6588_ioctl() function expects to get called from other kernel functions with a 'saa6588_command' pointer, but I found nothing stops it from getting called from user space instead, which seems rather dangerous. The same thing happens in the davinci vpbe driver with its VENC_GET_FLD command. As a quick fix, add a separate .command() callback pointer for this driver and change the two callers over to that. This change can easily get backported to stable kernels if necessary, but since there are only two drivers, we may want to eventually replace this with a set of more specialized callbacks in the long run.

2021-06-17media: v4l2-subdev: add subdev-wide state structTomi Valkeinen1-30/+44
We have 'struct v4l2_subdev_pad_config' which contains configuration for a single pad used for the TRY functionality, and an array of those structs is passed to various v4l2_subdev_pad_ops. I was working on subdev internal routing between pads, and realized that there's no way to add TRY functionality for routes, which is not pad specific configuration. Adding a separate struct for try-route config wouldn't work either, as e.g. set-fmt needs to know the try-route configuration to propagate the settings. This patch adds a new struct, 'struct v4l2_subdev_state' (which at the moment only contains the v4l2_subdev_pad_config array) and the new struct is used in most of the places where v4l2_subdev_pad_config was used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config are changed to instead take v4l2_subdev_state. The changes to drivers/media/v4l2-core/v4l2-subdev.c and include/media/v4l2-subdev.h were written by hand, and all the driver changes were done with the semantic patch below. The spatch needs to be applied to a select list of directories. I used the following shell commands to apply the spatch: dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media" for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done Note that Coccinelle chokes on a few drivers (gcc extensions?). With minor changes we can make Coccinelle run fine, and these changes can be reverted after spatch.

2021-06-08media: videobuf2-v4l2.c: add vb2_queue_change_type() helperTomi Valkeinen1-0/+16
On some platforms a video device can capture either video data or metadata. The driver can implement vidioc functions for both video and metadata, and use a single vb2_queue for the buffers. However, vb2_queue requires choosing a single buffer type, which conflicts with the idea of capturing either video or metadata. The buffer type of vb2_queue can be changed, but it's not obvious how this should be done in the drivers. To help this, add a new helper function vb2_queue_change_type() which ensures the correct checks and documents how it can be used.

2021-05-23media: uapi: mpeg2: Remove V4L2_CID_MPEG_VIDEO_MPEG2_SLICE_PARAMSEzequiel Garcia2-18/+0
The Hantro and Cedrus drivers work in frame-mode, meaning they expect all the slices in a picture (either frame or field structure) to be passed in each OUTPUT buffer. These two are the only V4L2 MPEG-2 stateless decoders currently supported. Given the VA-API drivers also work per-frame, coalescing all the MPEG-2 slices in a buffer before the decoding operation, it makes sense to not expect slice-mode drivers and therefore remove V4L2_CID_MPEG_VIDEO_MPEG2_SLICE_PARAMS. This is done to avoid carrying an unused interface. If needed, this control can be added without breaking backwards compatibility. Note that this would mean introducing a enumerator control to specify the decoding mode (see V4L2_CID_STATELESS_H264_DECODE_MODE).

2021-05-23media: uapi: mpeg2: Split sequence and picture parametersEzequiel Garcia2-23/+86
Typically, bitstreams are composed of a sequence header, followed by a number of picture header and picture coding extension headers. Each picture can be composed of a number of slices. Let's split the MPEG-2 uAPI to follow these semantics more closely, allowing more usage flexibility. Having these controls split up allows applications to set a sequence control at the beginning of a sequence, and then set a picture control for each frame. While here add padding fields where needed, and document the uAPI header thoroughly. Note that the V4L2_CTRL_TYPE_{} defines had to be moved because it clashes with existing ones. This is not really an issue since they will be re-defined when the controls are moved out of staging.

2021-05-23media: uapi: mpeg2: rework quantisation matrices semanticsEzequiel Garcia1-5/+0
As stated in the MPEG-2 specification, section 6.3.7 "Quant matrix extension": Each quantisation matrix has a default set of values. When a sequence_header_code is decoded all matrices shall be reset to their default values. User defined matrices may be downloaded and this can occur in a sequence_header() or in a quant_matrix_extension(). The load_intra_quantiser_matrix syntax elements are transmitted in the bitstream headers, signalling that a quantisation matrix needs to be loaded and used for pictures transmitted afterwards (until the matrices are reset). This "load" semantics are implemented in the V4L2 interface without the need of any "load" flags: passing the control is effectively a load. Therefore, rework the V4L2_CID_MPEG_VIDEO_MPEG2_QUANTISATION semantics to match the MPEG-2 semantics. Quantisation matrices values are now initialized by the V4L2 control core to their reset default value, and applications are expected to reset their values as specified. The quantisation control is therefore optional, and used to load bitstream-defined values in the quantisation matrices.

2021-04-15media: v4l2-ctrls: fix reference to freed memoryHans Verkuil1-5/+7
When controls are used together with the Request API, then for each request a v4l2_ctrl_handler struct is allocated. This contains the controls that can be set in a request. If a control is *not* set in the request, then the value used in the most recent previous request must be used, or the current value if it is not found in any outstanding requests. The framework tried to find such a previous request and it would set the 'req' pointer in struct v4l2_ctrl_ref to the v4l2_ctrl_ref of the control in such a previous request. So far, so good. However, when that previous request was applied to the hardware, returned to userspace, and then userspace would re-init or free that request, any 'ref' pointer in still-queued requests would suddenly point to freed memory. This was not noticed before since the drivers that use this expected that each request would always have the controls set, so there was never any need to find a control in older requests. This requirement was relaxed, and now this bug surfaced. It was also made worse by changeset 2fae4d6aabc8 ("media: v4l2-ctrls: v4l2_ctrl_request_complete() should always set ref->req") which increased the chance of this happening. The use of the 'req' pointer in v4l2_ctrl_ref was very fragile, so drop this entirely. Instead add a valid_p_req bool to indicate that p_req contains a valid value for this control. And if it is false, then just use the current value of the control. Note that VIDIOC_G_EXT_CTRLS will always return -EACCES when attempting to get a control from a request until the request is completed. And in that case, all controls in the request will have the control value set (i.e. valid_p_req is true). This means that the whole 'find the most recent previous request containing a control' idea is pointless, and the code can be simplified considerably. The v4l2_g_ext_ctrls_common() function was refactored a bit to make it more understandable. It also avoids updating volatile controls in a completed request since that was already done when the request was completed.

2021-03-22media: uapi: move VP8 stateless controls out of stagingEzequiel Garcia2-211/+0
Until now, the VP8 V4L2 API was not exported as a public API, and only defined in a private media header (media/vp8-ctrls.h). The reason for this was a concern about the API not complete and ready to support VP8 decoding hardware accelerators. After reviewing the VP8 specification in detail, and now that the API is able to support Cedrus and Hantro G1, we can consider this ready.
