I did test the kernel from lunar proposed (6.2.0.1015.16) on AWS. The
image boots with sev-snp enabled:
# sudo dmesg | grep -i sev
[ 5.563677] Memory Encryption Features active: AMD SEV SEV-ES SEV-SNP
[ 6.140250] SEV: Using SNP CPUID table, 64 entries present.
[ 8.507286] SEV: SNP guest platform device initialized.
[ 20.829729] sev-guest sev-guest: Initialized SEV guest driver (using
vmpck_id 0)
# apt-cache policy linux-aws

Bug description:
[Impact]
* Kernel fails to boot on SEV-SNP instances when compiled with GCC
12.3.0
[Fix]
*
https://lore.kernel.org/lkml/[email protected]/
[Test Case]
* Compile tested
* Boot tested
* Tested by Google
[Where things could go wrong]
* Patches relatively isolated and maintain similar checking
functionality, just earlier in boot. Likely a low chance of
regression.
