How OpenWRT drives AMD Core Graphics

Installing and Using OpenWrt
1

My CPU is AMD A8-7410 APU with AMD Radeon R5 Graphics x 4C 4T

opkg update
opkg install radeon-firmware

After adding AMDGPU firmware, checking the graphics card through ls/dev/DRI shows that the path cannot be found

[ root@OpenWrt :11:48 PM ~] # ls /dev/dri/
ls: /dev/dri/: No such file or directory

I also tried modifying the boot file grub.cfg and adding
radeon. si_Support=1 radeon. cik_support=1
Still not working

You talking about AMD Radeon or Intel Core?
What problem are you trying to solve?

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

OpenWrt more or less doesn't, all acceleration is disabled and only VGA/ console modes in use.

Openwrt uses only fbdev part of graphics driver

It appears you are using firmware that is not from the official OpenWrt project.

When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.

You may find that the best options are:

  1. Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
  2. Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
  3. Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).

If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.

Because I compiled it myself and encountered an error
So I used online compilation, not a customized version
The system's signature Kiddin 'is the author of the online compilation website

Whom you should be asking first because of added graphics patches.

Okay, thank you

You can run desktop linux to drive graphics and hide network routers in (kvm) virtual machines,
