Subject: [PATCH] migration/ram: Force encrypted status for flash0 & flash1
|
|
devices.
|
|
|
|
cherry-picked from https://github.com/AMDESE/qemu/commit/803d6a4c8d.
|
|
|
|
Currently OVMF clears the C-bit and marks NonExistent memory space
|
|
as decrypted in the page encryption bitmap. By marking the
|
|
NonExistent memory space as decrypted it gurantees any future MMIO adds
|
|
will work correctly, but this marks flash0 device space as decrypted.
|
|
At reset the SEV core will be in forced encrypted state, so this
|
|
decrypted marking of flash0 device space will cause VCPU reset to fail
|
|
as flash0 device pages will be migrated incorrectly.
