this is odd.  i believe your card is pciid 0x699F?  that should be
matching eg:

        {0x1002, 0x699F, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_POLARIS12},

from sys/external/bsd/drm2/dist/drm/amd/amdgpu/amdgpu_drv.c.

does turning on that option enable some other code that makes your
chipset work?  AMDGPU_CIK (and similar option AMDGPU_SI) are not
enabled upstream by default (and the devices supported, don't work
for me anyway.)

assuming i'm right, and it tries to attach without AMDGPU_CIK set?

thanks.
