While queue_setup was correct for CREATE_BUFS support for video devices, for VBI, SDR and touch devices it was wrong. This was found after adding new v4l2-compliance tests. Signed-off-by: -

In several places a division by fmt->vdownsampling[p] was missing in the sizeimage[p] calculation, causing incorrect behavior for multiplanar formats were some planes are smaller than the first plane. Found by new v4l2-compliance tests. Signed-off-by: -

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. To differentiate them from the rest of the device private data, move the corresponding fields to a sub-structure of vimc_scaler_device named hw. Signed-off-by:

smatch generated this warning: drivers/media/usb/b2c2/flexcop-usb.c:199 flexcop_usb_memory_req() warn: iterator 'i' not incremented and indeed the function is not using i or updating buf. The reason this always worked is that this function is called to write just 6 bytes (a MAC address) to the USB device, and so in practice there is only a single chunk written. If we ever would need to write more than one chunk, this function would fail since each chunk would read from or write to the same buf address. Rewrite the function to properly handle this.

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. Signed-off-by:

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.

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:
