Problems with AMD ryzen 7 7700 build-in gpu

[SirJiga]

I installed the system on amd ryzen 7 7700, I use the integrated video card. The system is the latest version, 14.2-RELEASE. When loading the amdgpu module, I get a black screen, the same color as a turned off monitor. Also, I can not enter another tty. I guess that DRM does not yet have support for my card on FreeBSD, because on all Linux distributions that I used, there were no problems.

There is pciconf -lv output:

 vgapci0@pci0:15:0:0: class=0x030000 rev=0xc5 hdr=0x00 vendor=0x1002 device=0x164e subvendor=0x1462 subdevice=0x7e2  
         vendor   = 'Advanced Micro Devices, Inc [AMD/ATI]
          device    =  'Raphael'
          class      =  display
          subclass = VGA

Please tell me how can we fix it if this possible at all
Thank you

I have the exact same CPU. The integrated GPU of Ryzen 7000 series is not yet supported, and the available drm-kmod-6.1-lts cannot (and will not?) support it. If I remember correctly, we need Linux 6.6 at least, for initial Ryzen 7000 GPU support, and supposedly Linux 5.19 -- if it gets backported. This also applies to FreeBSD-CURRENT.
The only option for now, is to install a dedicated GPU card for display. I use a Radeon Pro WX 3200, which can be found for very little money.
You need to make sure to disable the integrated GPU in UEFI/BIOS, otherwise you will get the same kernel lockup, when the AMDGPU kernel module is loaded & tries to attach to the iGPU instead of the dGPU.

If it is at all helpful, here is a list of GPUs that I have personally tested:

Note: There are some Linux/Windows reports among them -- pay close attention.
The Ryzen 7000 iGPU is identified by "[AMD Radeon Graphics (RADV RAPHAEL_MENDOCINO)]" in that list -- reported, yes, but currently remains nonfunctional. In case you are curious, the iGPU of Ryzen 9000 identifies exactly the same -- hopefully these 2 iGPUs are similar enough that we may obtain support for both when 6.6-lts lands. Running FreeBSD on a Ryzen 9700X is ridiculously fast, very impressive performance so far.
