Video node formats have direct dependency by the sub-device pad formats. Remove dependency for SoC version and move format definitions in device which creates video node. This commit attaches a struct to the VFE resources that holds format description, so it is much easier to assign them to the video node. No need to use a switch-case. NOTE: The mbus_bpp is used to calculate the clock rates and is different from bpp which is the bits per pixel written to memory. We need to keep both values to not break the calcualtions.

2024-06-28media: vivid: loopback based on 'Connected To' controlsHans Verkuil11-277/+362
Instead of using hardwired video loopback limited to a single vivid instance, use the new 'Connected To' controls to only loopback if an HDMI or S-Video input is connected to another output, which can be in another vivid instance. Effectively this emulates connecting and disconnecting an HDMI/S-Video cable. The Loop Video control is dropped since it has now been replaced by the new 'Connected To' controls. The Display Present has also been dropped since it no longer fits.

2024-06-28media: vivid: Add 'Is Connected To' menu controlsDorcas Anono Litunya3-17/+401
The video loopback functionality in vivid is very crude. What we really want is to be able to emulate connecting an HDMI or S-Video input to an HDMI or S-Video output, and the input and output can be in different vivid instances. Effectively this emulates what happens when you physically connect an HDMI or S-Video cable between two devices. In particular, this makes prototyping with vivid much more realistic. This patch creates a menu control for each HDMI or S-Video input. The menu control starts with "Test Pattern Generator" and "None" (i.e. disconnected). After that up to 62 HDMI or S-Video outputs are listed that you can connect the input to. If there are more than 62 HDMI or S-Video outputs, then those will not be included in the menu (currently menucontrols have max 64 entries). If an input is connected to an output, then all other 'Connected To' controls are updated to exclude that output to avoid having multiple inputs connected to the same output.

2024-06-28media: vivid: add instance number to input/output namesHans Verkuil2-12/+12
Add the instance number before the input or output number. So "HDMI 1" becomes "HDMI 000-1". This is helps identifying which input or output belongs to which vivid instance. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
2024-06-28media: vivid: don't set HDMI TX controls if there are no HDMI outputsHans Verkuil1-4/+8
When setting the EDID it would attempt to update two controls that are only present if there is an HDMI output configured. If there isn't any (e.g. when the vivid module is loaded with node_types=1), then calling VIDIOC_S_EDID would crash. Fix this by first checking if outputs are present.

2024-06-28media: vivid: vidioc_g_edid: do not change the original input EDIDHans Verkuil2-4/+22
Returning an EDID for a connected output would modify the original input EDID with the physical address of the output. That causes problems, and it should just update the physical address of the output EDID. Update vivid_hdmi_edid to set the physical address to 0.0.0.0.

To support sources that implement the .enable_streams() and .disable_streams() operations, replace the manual calls to the subdev .s_stream() operation with the v4l2_subdev_enable_streams() and v4l2_subdev_disable_streams() helpers. The helpers fall back to .s_stream() if the source doesn't implement the new operations, so backward compatibility is preserved.

2024-06-26media: vimc: scaler: Use subdev active stateLaurent Pinchart1-75/+49
Store the active formats and crop rectangle in the subdevice active state. This simplifies implementation of the format and selection accessors, and allows using the v4l2_subdev_get_fmt() helper to implement the .get_fmt() operation. The active configuration that is used in the .process_frame() handler is still stored in the vimc_scaler_device structure. The driver could instead access the active state in the .process_frame() handler, but the required locking could interfere with the real time constraints of the frame processing. This data would be stored in registers in the .s_stream() handler for real hardware, storing it in dedicated storage thus mimics a real driver.

2024-06-24media: v4l2-jpeg: Export reference quantization and huffman tablesDevarsh Thakkar1-0/+116
Export reference quantization and huffman tables as provided in ITU-T.81 so that they can be re-used by other JPEG drivers. These are example tables provided in ITU-T.81 as reference tables and the JPEG encoders are free to use either these or their own proprietary tables. Also add necessary prefixes to be used for huffman tables in global header file.

2024-06-24media: imagination: Add E5010 JPEG Encoder driverDevarsh Thakkar10-0/+3131
This adds support for stateful V4L2 M2M based driver for Imagination E5010 JPEG Encoder [1] which supports baseline encoding with two different quantization tables and compression ratio as demanded. Support for both contiguous and non-contiguous YUV420 and YUV422 semiplanar formats is added along with alignment restrictions as required by the hardware. System and runtime PM hooks are added in the driver along with v4l2 crop and selection API support. Minimum resolution supported is 64x64 and Maximum resolution supported is 8192x8192. All v4l2-compliance tests are passing [2] : v4l2-compliance -s -f -a -d /dev/video0 -e /dev/video1 Total for e5010 device /dev/video0: 79, Succeeded: 79, Failed: 0, Warnings: 0 NOTE: video1 here is VIVID test pattern generator Also tests [3] were run manually to verify below driver features: - Runtime Power Management - Multi-instance JPEG Encoding - DMABUF import, export support - NV12, NV21, NV16, NV61 video format support - Compression quality S_CTRL - Cropping support using S_SELECTION Existing V4L2 M2M based JPEG drivers namely s5p-jpeg, imx-jpeg and rcar_jpu were referred while making this.

2024-06-21media: chips-media: wave5: support Wave515 decoderIvan Bornyakov10-79/+280
Add initial support for the Wave515 multi-decoder IP. For now it is only able to decode HEVC Main/Main10 profile videos into YUV420. This was tested on FPGA prototype, so wave5_dt_ids[] was not expanded. Users of the real hardware with Wave515 IP will have to * provide firmware specific to their SoC * add struct wave5_match_data like this: static const struct wave5_match_data platform_name_wave515_data = { .flags = WAVE5_IS_DEC, .fw_name = "cnm/wave515_platform_name_fw.bin", .sram_size = (71 * 1024), }; * add item to wave5_dt_ids[] like this: { .compatible = "vendor,soc-wave515", .data = &platform_name_wave515_data, }, * describe new compatible in Documentation/devicetree/bindings/media/cnm,wave521c.yaml Signed-off-by: Ivan Bornyakov <brnkv.i1@gmail.com> Signed-off-by: Sebastian Fricke <sebastian.fricke@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>

Move the excessive "sram-size" device-tree property to the device match data. Also change the SRAM memory allocation strategy, instead of allocating exactly sram_size bytes, allocate all available SRAM memory up to sram_size. Add the placeholders wave5_vpu_dec_validate_sec_axi() and wave5_vpu_enc_validate_sec_axi() to validate that the allocated SRAM memory is sufficient to decode/encode bitstream with a given resolution.

Implement a separate setup routine for interrupts to reduce code duplication. Also enable interrupts based on vpu_attr->support_encoders and vpu_attr->support_decoders fields to facilitate support for other Wave5xx IPs, because not all of them are both encoders and decoders.
