Subject: Remove noefi and acpi_rsdp for EFI firmware
|
||
|
|
References: bsc#1123940

Upstream: merged

Git-commit: 3ea13723f93cc22d163f1f1c8e64ccef3fa32471
|
||
|
|
|
||
|
|
The noefi and acpi_rsdp can be removed because kernel passes necessary
|
||
|
|
EFI data for kexec via setup_data since 1fec05336 patch be introduced
|
||
|
|
in v3.14 kernel. (bsc#1098210)
|
||
|
|
|
||
|
|
On the other hand, the MOK (machine owner key) doesn't work with noefi.
|
||
|
|
It causes that third-party signed kernel modules can not be loaded by
|
||
|
|
crash kernel. Crash kernel can provide EFI runtime services for loading
|
||
|
|
MOK after noefi be removed. (bsc#1123940)
|
||
|
|
|
||
|
|
The kdump without noefi has been tested on Huawei Kunlun, Intel
|
||
|
|
minnowboard and KVM-OVMF.
