2020-06-23media: cec: remove unused waitq and phys_addrs fieldsHans Verkuil3-7/+0
The cec_adapter struct contained a waitq field that isn't used anywhere, so drop this. It also contained a phys_addrs array to store any reported physical addresses. However, this was never actually used, so this field is removed as well. The original idea was to let the core keep track of this information, but nothing was ever done with this.

2020-06-23media: pci: ttpci: av7110: fix possible buffer overflow caused by bad DMA ↵Jia-Ju Bai1-2/+3
value in debiirq() The value av7110->debi_virt is stored in DMA memory, and it is assigned to data, and thus data[0] can be modified at any time by malicious hardware. In this case, "if (data[0] < 2)" can be passed, but then data[0] can be changed into a large number, which may cause buffer overflow when the code "av7110->ci_slot[data[0]]" is used. To fix this possible bug, data[0] is assigned to a local variable, which replaces the use of data[0].

2020-06-23media: docs-rst: Document memory-to-memory video encoder interfaceTomasz Figa5-20/+767
Due to complexity of the video encoding process, the V4L2 drivers of stateful encoder hardware require specific sequences of V4L2 API calls to be followed. These include capability enumeration, initialization, encoding, encode parameters change, drain and reset. Specifics of the above have been discussed during Media Workshops at LinuxCon Europe 2012 in Barcelona and then later Embedded Linux Conference Europe 2014 in Düsseldorf. The de facto Codec API that originated at those events was later implemented by the drivers we already have merged in mainline, such as s5p-mfc or coda. The only thing missing was the real specification included as a part of Linux Media documentation. Fix it now and document the encoder part of the Codec API.

We moved cache management decision making to the upper layer and rely on buffer's need_cache_sync flags and videobuf2 core. If the upper layer (core) has decided to invoke ->prepare() or ->finish() then we must sync. For DMABUF ->need_cache_sync_on_prepare and ->need_cache_sync_on_flush are always false so videobuf core does not call ->prepare() and ->finish() on such buffers.

This patch lets user-space to request a non-consistent memory allocation during CREATE_BUFS and REQBUFS ioctl calls. = CREATE_BUFS struct v4l2_create_buffers has seven 4-byte reserved areas, so reserved[0] is renamed to ->flags. The struct, thus, now has six reserved 4-byte regions. = CREATE_BUFS32 struct v4l2_create_buffers32 has seven 4-byte reserved areas, so reserved[0] is renamed to ->flags. The struct, thus, now has six reserved 4-byte regions. = REQBUFS We use one bit of a ->reserved[1] member of struct v4l2_requestbuffers, which is now renamed to ->flags. Unlike v4l2_create_buffers, struct v4l2_requestbuffers does not have enough reserved room. Therefore for backward compatibility ->reserved and ->flags were put into anonymous union.

By setting or clearing V4L2_FLAG_MEMORY_NON_CONSISTENT flag user-space should be able to set or clear queue's NON_CONSISTENT ->dma_attrs. Queue's ->dma_attrs are passed to the underlying allocator in __vb2_buf_mem_alloc(), so thus user-space is able to request vb2 buffer's memory to be either consistent (coherent) or non-consistent. The patch set also adds a corresponding capability flag: fill_buf_caps() reports V4L2_BUF_CAP_SUPPORTS_MMAP_CACHE_HINTS when queue supports user-space cache management hints. Note, however, that MMAP_CACHE_HINTS capability only valid when the queue is used for memory MMAP-ed streaming I/O.

2020-06-23media: videobuf2: add cache management membersSergey Senozhatsky1-0/+10
Extend vb2_buffer and vb2_queue structs with cache management members. V4L2 UAPI already contains two buffer flags which user-space, supposedly, can use to control buffer cache sync: - V4L2_BUF_FLAG_NO_CACHE_INVALIDATE - V4L2_BUF_FLAG_NO_CACHE_CLEAN None of these, however, do anything at the moment. This patch set is intended to change it. Since user-space cache management hints are supposed to be implemented on a per-buffer basis we need to extend vb2_buffer struct with two new members ->need_cache_sync_on_prepare and ->need_cache_sync_on_finish, which will store corresponding user-space hints. In order to preserve the existing behaviour, user-space cache managements flags will be handled only by those drivers that permit user-space cache hints. That's the purpose of vb2_queue ->allow_cache_hints member. Driver must set ->allow_cache_hints during queue initialisation to enable cache management hints mechanism.

The Xilinx MIPI CSI-2 Rx Subsystem soft IP is used to capture images from MIPI CSI-2 camera sensors and output AXI4-Stream video data ready for image processing. Please refer to PG232 for details. The CSI2 Rx controller filters out all packets except for the packets with data type fixed in hardware. RAW8 packets are always allowed to pass through. It is also used to setup and handle interrupts and enable the core. It logs all the events in respective counters between streaming on and off. The driver supports only the video format bridge enabled configuration. Some data types like YUV 422 10bpc, RAW16, RAW20 are supported when the CSI v2.0 feature is enabled in design. When the VCX feature is enabled, the maximum number of virtual channels becomes 16 from 4.
