You need to provide more informations. I wasn't able to repreoduce. I works here.

What you’re seeing is open-source maintenance in practice. It’s not centrally orchestrated. We only manage to do this for some key features while DVB support is present in some kernels, but it’s not guaranteed to be consistently enabled across all targets unless someone explicitly maintains this functionality. -> https://github.com/armbian/build/pulls

Looks like both current and edge on sunxi64 are missing dvb support. Is this intentional? sunxi kernels include it, as do most other families.

@Nick A Great! and Good job! I've tested both the server and desktop versions of v0.6.4 on the A7S, and the DP output works perfectly on both. I've attached a screenshot for your reference. I’m using a USB‑C to HDMI docking station to test it. When I repeatedly plug and unplug it, the display works fine. The dock also has a keyboard receiver plugged in, which works normally. However, if I then plug a USB flash drive into the dock, the display output stops working (probably due to power supply issues). If I unplug the USB drive and plug it back in, the display works normally again. Additionally, I tested the Mainline v0.1. It seems to have issues on the A7S: the blue LED flashes after boot, but neither the Ethernet nor WiFi connects, and there is no output on the DP port. It appears the system cannot be login (I haven't tested via UART). However, the A7Z handles dual screens fine over HDMI and DP.

$ grep -i error /var/log/armbian-hardware-monitor.log [ 2.990779] rockchip-pcie f8000000.pcie: probe with driver rockchip-pcie failed with error -110 Looking at this I see the following: https://patchwork.ozlabs.org/project/linux-pci/patch/20210421083115.30213-1-jinsiyu940203@163.com/ "In function rockchip_pcie_host_init_port(), it defines a timeout value of 500ms to wait for pcie training.

So set a proper timeout value is important. Change the value to 1000ms will fix this bug." Is it possible for team to add patch such as ../patch/kernel/rockchip64-current/0002-rockchip-pcie-increase-timeout.patch which contains the fix specified in the patchwork.ozlabs.org link above? A humble thank you for any more help and consideration on this!
