[PATCH v3 3/4] x86/boot/compressed: Skip Video Memory access in Decompressor for SEV-ES/SNP.

2024-04-04 Thread Ashish Kalra
From: Ashish Kalra Accessing guest video memory/RAM during kernel decompressor causes guest termination as boot stage2 #VC handler for SEV-ES/SNP systems does not support MMIO handling. This issue is observed with SEV-ES/SNP guest kexec as kexec -c adds screen_info to the boot parameters passed
