Features that are currently supported by the HDMI RX driver have been tested on rock5b board using a HDMI to micro-HDMI cable. It is recommended to use a good quality cable as there were multiple issues seen during testing the driver. Please note the below information :- * HDMIRX driver now only works with the opensource TF-A. * We have tested the working of OBS studio with HDMIRX driver and there were no issues seen. * We also tested and verified the support for interlaced video. To test the HDMI RX Controller driver, following example commands can be used :- root@debian-rockchip-rock5b-rk3588:~# v4l2-ctl --verbose -d /dev/video0 \ --set-fmt-video=width=1920,height=1080,pixelformat='BGR3' --stream-mmap=4 \ --stream-skip=3 --stream-count=100 --stream-to=/home/hdmiin4k.raw --stream-poll root@debian-rockchip-rock5b-rk3588:~# ffmpeg -f rawvideo -vcodec rawvideo \ -s 1920x1080 -r 60 -pix_fmt bgr24 -i /home/hdmiin4k.raw output.mkv CEC compliance test results :- * https://gitlab.collabora.com/-/snippets/380 * https://gitlab.collabora.com/-/snippets/381 Following is the v4l2-compliance test result :- root@debian-rockchip-rock5b-rk3588:~# v4l2-compliance -d /dev/video0 v4l2-compliance 1.29.0-5278, 64 bits, 64-bit time_t v4l2-compliance SHA: 791da13728d9 2024-11-25 10:01:57 Compliance test for snps_hdmirx device /dev/video0: Driver Info: Driver name : snps_hdmirx Card type : snps_hdmirx Bus info : platform:fdee0000.hdmi_receiver Driver version : 6.12.0 Capabilities : 0x84201000 Video Capture Multiplanar Streaming Extended Pix Format Device Capabilities Device Caps : 0x04201000 Video Capture Multiplanar Streaming Extended Pix Format Required ioctls: test VIDIOC_QUERYCAP: OK test invalid ioctls: OK Allow for multiple opens: test second /dev/video0 open: OK test VIDIOC_QUERYCAP: OK test VIDIOC_G/S_PRIORITY: OK test for unlimited opens: OK Debug ioctls: test VIDIOC_DBG_G/S_REGISTER: OK (Not Supported) test VIDIOC_LOG_STATUS: OK Input ioctls: test VIDIOC_G/S_TUNER/ENUM_FREQ_BANDS: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_S_HW_FREQ_SEEK: OK (Not Supported) test VIDIOC_ENUMAUDIO: OK (Not Supported) test VIDIOC_G/S/ENUMINPUT: OK test VIDIOC_G/S_AUDIO: OK (Not Supported) Inputs: 1 Audio Inputs: 0 Tuners: 0 Output ioctls: test VIDIOC_G/S_MODULATOR: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_ENUMAUDOUT: OK (Not Supported) test VIDIOC_G/S/ENUMOUTPUT: OK (Not Supported) test VIDIOC_G/S_AUDOUT: OK (Not Supported) Outputs: 0 Audio Outputs: 0 Modulators: 0 Input/Output configuration ioctls: test VIDIOC_ENUM/G/S/QUERY_STD: OK (Not Supported) test VIDIOC_ENUM/G/S/QUERY_DV_TIMINGS: OK test VIDIOC_DV_TIMINGS_CAP: OK test VIDIOC_G/S_EDID: OK Control ioctls (Input 0): test VIDIOC_QUERY_EXT_CTRL/QUERYMENU: OK test VIDIOC_QUERYCTRL: OK test VIDIOC_G/S_CTRL: OK test VIDIOC_G/S/TRY_EXT_CTRLS: OK test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: OK test VIDIOC_G/S_JPEGCOMP: OK (Not Supported) Standard Controls: 4 Private Controls: 0 Format ioctls (Input 0): test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: OK test VIDIOC_G/S_PARM: OK test VIDIOC_G_FBUF: OK (Not Supported) test VIDIOC_G_FMT: OK test VIDIOC_TRY_FMT: OK test VIDIOC_S_FMT: OK test VIDIOC_G_SLICED_VBI_CAP: OK (Not Supported) test Cropping: OK (Not Supported) test Composing: OK (Not Supported) test Scaling: OK (Not Supported) Codec ioctls (Input 0): test VIDIOC_(TRY_)ENCODER_CMD: OK (Not Supported) test VIDIOC_G_ENC_INDEX: OK (Not Supported) test VIDIOC_(TRY_)DECODER_CMD: OK (Not Supported) Buffer ioctls (Input 0): test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: OK test CREATE_BUFS maximum buffers: OK test VIDIOC_REMOVE_BUFS: OK test VIDIOC_EXPBUF: OK test Requests: OK (Not Supported) test blocking wait: OK Total for snps_hdmirx device /dev/video0: 48, Succeeded: 48, Failed: 0, Warnings: 0 --- Resending the patch series due to mail server timeout issue when sending v5 patchset Changes in v5 :- - Fix the interrupt IRQ number in the dt-bindings and device tree - Add alignment property to ensure hdmi-receiver-cma starts at a 64KB-aligned address - Change the MODULE_DESCRIPTION - Add VIDEO_SYNOPSYS_HDMIRX as prefix to the default edid config - Drop the enabling of default edid in the Kconfig - Replace the default EDID with hdmi-4k-300mhz EDID produced by v4l2-ctl tool for better compatibility with various HDMI cables and adapters - Rework the write_edid and set_edid functions - During format change, retrieve the current pixel format, color depth, and AVI infoframe details instead of only detecting the format - Improve the logging mechanism and delays in the hdmirx_wait_signal_lock function - Fix the 4K@60 capturing for RGB format - Document what hdmirx_check_timing_valid function does - Rework the hdmirx_get_detected_timings function - Fix the NV16/24 size image value - Add the implementation from Benjamin Hoff to expose the ITC type to v4l2 - Remove all the firmware related code Changes in v4 :- - Remove DTS changes included in the device tree patch - Remove the hdmi rx pin info as it's already present in the rk3588-base-pinctrl.dtsi - Create a separate config option for selecting the EDID and enable it by default -

Drop the bus info from hdmirx_querycap - If *num_planes != 0 then return 0 in hdmirx_queue_setup - Set queue->min_queued_buffers to 1 - Drop q->allow_cache_hints = 0; as it's always 0 by default - Add a comment for q->dma_attrs = DMA_ATTR_FORCE_CONTIGUOUS; - Drop .read = vb2_fop_read as it's not supported by driver - Remove redundant edid_init_data_600M - Make HPD low when driver is loaded - Add support for reading AVI Infoframe - Remove msg_len checks from hdmirx_cec_transmit -
