Bug#898783: linux-image-amd64: Raven Ridge not supported in debian kernel image

[Diego Roversi <diegor@tiscali.it>]

Package: linux-image-amd64
Version: 4.16+93
Severity: normal

Dear maintener,
  
  from version 4.15, linux support raven ridge gpu, but it need to be
enabled in the build config. 

  I've succed to enable gpu on a AMD Ryzen 2200G, changing this
following lines in linux config:

#
# Display Engine Configuration
#
CONFIG_DRM_AMD_DC=y
CONFIG_DRM_AMD_DC_PRE_VEGA=y
CONFIG_DRM_AMD_DC_FBC=y
CONFIG_DRM_AMD_DC_DCN1_0=y
# CONFIG_DEBUG_KERNEL_DC is not set

  Test was made using 4.17-rc4, but should work also with 4.16. I've
found the information on https://wiki.gentoo.org/wiki/AMDGPU .

  Note: it also need updated amdgpu firmware from upstream.

Thanks,
  Diego Roversi
