| From | Brijesh Singh <> | Subject | [PATCH Part2 RFC v4 31/40] KVM: X86: update page-fault trace to log the 64-bit error code | Date | Wed, 7 Jul 2021 13:36:07 -0500 |
| |
The page-fault error code is a 64-bit value, but the trace prints only the lower 32-bits. Some of the SEV-SNP RMP fault error codes are available in the upper 32-bits.
