Dear Tom, dear Linux folks,
Selecting the symbol `AMD_MEM_ENCRYPT` – as done in Debian 5.13.9-1~exp1
[1] – also selects `AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT`, as it defaults
to yes, causing boot failures on AMD Raven systems. On the MSI B350M
MORTAR with AMD Ryzen 3 2200G, Linux logs and the AMDGPU graphics
driver, despite being loaded, does not work, and the framebuffer driver
is used instead.
[ 19.679824] amdgpu 0000:26:00.0: amdgpu: SME is not compatible
with RAVEN
It even causes black screens on other systems as reported to the Debian
bug tracking system *Black screen on AMD Ryzen based systems (AMDGPU
related when AMD Secure Memory Encryption not disabled --
mem_encrypt=off)* [2].
Should the default be changed?
Kind regards,
Paul
