Currently the driver notifies internal subdevs if the signal is locked or not. This information is also useful for userpace applications e.g. to switch to another input device upon a signal lost event. This commit adds the support for the userspace to subscribe to the V4L2_EVENT_SOURCE_CHANGE and V4L2_EVENT_CTRL events. Signed-off-by:

As documented in [1] the runtime-pm ops are used to set the device into a fully 'workable' state. Therefore it can be used to enable or disable the irqs. [1] https://www.kernel.org/doc/html/latest/power/runtime_pm.htmlSigned-off-by:

There are several debug prints in the tvp5150_parse_dt() function, which do not print the prefix, because the v4l2_subdev is not initialized, yet. Initialize the v4l2_subdev before parsing the device tree to fix the debug messages. Signed-off-by:

Since commit 10d5509c ("[media] v4l2: remove g/s_crop from video ops") the 'which' field for set/get_selection must be FORMAT_ACTIVE. There is no way to try different selections. The patch adds a helper function to select the correct selection memory space (sub-device file handle or driver state) which will be set/returned. The selection rectangle is updated if the format is FORMAT_ACTIVE and the rectangle position and/or size differs from the current set rectangle. Signed-off-by:

Currently a local copy of sel->r is made and adapted to the hardware constraints. After the adaption the value is applied to the hardware but the driver forgot to reflect the adapted value to the user space. Drop the local copy and work directly on the requested rectangle instead to fix this. Signed-off-by:

The TVP5150/1 decoders support different video input sources to their AIP1A/B pins. Possible configurations are as follows: - Analog Composite signal connected to AIP1A. - Analog Composite signal connected to AIP1B. - Analog S-Video Y (luminance) and C (chrominance) signals connected to AIP1A and AIP1B respectively. This patch extends the device tree bindings documentation to describe how the input connectors for these devices should be defined in a DT. Signed-off-by: -
Marco Felsch authored
This patch adds the of_graph support to describe the tvp input connections. Physical the TVP5150 has three ports: AIP1A, AIP1B and YOUT. As result of discussion [1],[2] the device-tree maps these ports 1:1. Look at the Documentation for more information. Since the TVP5150 is a converter/bridge the device-tree must contain at least 1-input and 1-output port. The mc-connectors and mc-links are only created if the device-tree contains the corresponding connector nodes. If more than one connector is available the media_entity_operations.link_setup() callback ensures that only one connector is active.

Commit f7b4b54e ("[media] tvp5150: add HW input connectors support") added input signals support for the tvp5150, but the approach was found to be incorrect so the corresponding DT binding commit 82c2ffeb ("[media] tvp5150: document input connectors DT bindings") was reverted. This left the driver with an undocumented (and wrong) DT parsing logic, so lets get rid of this code as well until the input connectors support is implemented properly. It's a partial revert due other patches added on top of mentioned commit not allowing the commit to be reverted cleanly anymore. But all the code related to the DT parsing logic and input entities creation are removed. Suggested-by:

The patch adds the initial connector parsing code, so we can move from a driver specific parsing code to a generic one. Currently only the generic fields and the analog-connector specific fields are parsed. Parsing the other connector specific fields can be added by a simple callbacks. Signed-off-by:
-
Marco Felsch authored
Currently every driver needs to parse the connector endpoints by it self. This is the initial work to make this generic. A generic connector has common members and connector specific members. The common members are: - type - label (optional) - links - nr_of_links The specific members are stored within a union, since only one of them can be available at the time. Since this is the initial support the patch adds only the analog-connector specific ones. Signed-off-by:

Add defines which can be included to easily describe the supported standard tv norms 'sdtv-standards' within the device tree. Signed-off-by:
-
Marco Felsch authored
Some connectors no matter if in- or output supports only a limited range of sdtv standards. It doesn't matter if the hardware behind that connector supports more than the listed formats since the users are restriced by a label e.g. to plug only a camera into this connector which uses the PAL format. This patch adds the capability to describe such limitation within the firmware. There are no format restrictions if the property isn't present, so it's completely backward compatible. Signed-off-by:

When calling ccdc_data_size_max_bit() to validate data_sz in vpfe_ccdc_validate_param(), it's treated as an enumeration ranging from 0 to 7 while essentially it's an 32 bit unsigned integer directly from user space. This can make the return value of ccdc_data_size_max_bit() underflow and bypass the following check. To fix this, an additional check is added to the following if clause to keep this enumaration variable in range. And if its value is not legal, return -EINVAL properly. Signed-off-by:

After the switch to use v4l2_async_notifier_add_subdev() and v4l2_async_notifier_cleanup(), unloading the ti_cal module would cause a kernel oops. This was root cause to the fact that v4l2_async_notifier_cleanup() tries to kfree the asd pointer passed into v4l2_async_notifier_add_subdev(). In our case the asd reference was from a statically allocated struct. So in effect v4l2_async_notifier_cleanup() was trying to free a pointer that was not kalloc. So here we switch to using a kzalloc struct instead of a static one. To achieve this we re-order some of the calls to prevent asd allocation from leaking.

Previously, vpu->recv_buf and send_buf are forced cast from void __iomem *tcm. vpu->recv_buf->share_buf is passed to vpu_ipi_desc.handler(). It's not able to do unaligned access. Otherwise kernel would crash due to unable to handle kernel paging request. struct vpu_run { u32 signaled; char fw_ver[VPU_FW_VER_LEN]; unsigned int dec_capability; unsigned int enc_capability; wait_queue_head_t wq; }; fw_ver starts at 4 byte boundary. If system enables CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS, strscpy() will do read_word_at_a_time(), which tries to read 8-byte: *(unsigned long *)addr vpu_init_ipi_handler() calls strscpy(), which would lead to crash. vpu_init_ipi_handler() and several other handlers (eg. vpu_dec_ipi_handler) only do read access to this data, so they can be const, and we can use memcpy_fromio() to copy the buf to another non iomem buffer then pass to handler.

The shifting of buf[3] by 24 bits to the left will be promoted to a 32 bit signed int and then sign-extended to an unsigned long. In the unlikely event that the the top bit of buf[3] is set then all then all the upper bits end up as also being set because of the sign-extension and this affect the ev->post_bit_error sum. Fix this by using the temporary u32 variable bit_error to avoid the sign-extension promotion. This also removes the need to do the computation twice.

The ds3103b demodulator identifies as an m88rs600, but requires different clock settings and firmware, along with differences in register settings. Changes were reverse engineered using an instrumented downstream GPLv2 driver to compare i2c traffic and clocking. The mclk functions are from the downstream GPLv2 driver. Signed-off-by:

There are many protocols that encode more than 32 bit. We want 64 bit support so that BPF IR decoders can decode more than 32 bit. None of the existing kernel IR decoders/encoders support 64 bit, for now. The MSC_SCAN event can only contain 32 bit scancodes, so we only generate MSC_SCAN events if the scancode fits into 32 bits. The full 64 bit scancode can be read from the lirc chardev. Signed-off-by:

This adds VP9 decoding for the Amlogic GXL, G12A & SM1 SoCs, using the commong "HEVC" HW decoder. For G12A & SM1, it uses the IOMMU support from the firmware. For 10bit decoding, the firmware can only decode in the proprietary Amlogic Framebuffer Compression format, but can output in 8bit NV12 buffer while writing the decoded frame. Signed-off-by:

Amlogic VP9 decoder requires an additional 16-byte payload before every frame header. The source buffer is updated in-place, then given to the Parser FIFO DMA. The FIFO DMA copies the blocks into the 16MiB parser ring buffer, then parses and copies the slice into the decoder "workspace". Signed-off-by:

Since the draining and stop phase of the HW decoder mem2mem bahaviour is now clearly defined, we can move handling of the following states to the common v4l2-mem2mem core code: - draining - stopped - next-buf-is-last By introducing the following v4l2-mem2mem APIs: - v4l2_m2m_encoder_cmd/v4l2_m2m_ioctl_encoder_cmd to handle start/stop command - v4l2_m2m_decoder_cmd/v4l2_m2m_ioctl_decoder_cmd to handle start/stop command - v4l2_m2m_update_start_streaming_state to update state on start of streaming of the de/encoder queue - v4l2_m2m_update_stop_streaming_state to update state on stop of streaming of the de/encoder queue - v4l2_m2m_last_buffer_done to make the current dest buffer as the last one And inline helpers: - v4l2_m2m_mark_stopped to mark the de/encoding process as stopped - v4l2_m2m_clear_state to clear the de/encoding state - v4l2_m2m_dst_buf_is_last to detect the current dequeued dst_buf is the last - v4l2_m2m_has_stopped to detect the de/encoding stopped state - v4l2_m2m_is_last_draining_src_buf to detect the current source buffer should be the last processing before stopping the de/encoding process The special next-buf-is-last when min_buffers != 1 case is also handled in v4l2_m2m_qbuf() by reusing the other introduced APIs. This state management has been stolen from the vicodec implementation, and is no-op for drivers not calling the v4l2_m2m_encoder_cmd or v4l2_m2m_decoder_cmd and v4l2_m2m_update_start/stop_streaming_state. The vicodec will be the first one to be converted as an example. Signed-off-by:

When the request is completed, all controls are copied to the request object. However, when VIDIOC_G_EXT_CTRLS attempts to read control values from the request it will read the current value instead for any control reference that has a NULL ref->req pointer. But that's wrong: after completing the request *all* controls should have a non-NULL ref->req pointer since they are after all copied to the request. So set ref->req if it wasn't set already.
