[kvm-unit-tests PATCH v2 1/4] x86 EFI: Bypass call to fdt_check_header()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Issuing a call to fdt_check_header() prevents running any of x86 UEFI
enabled tests. Bypass this call for x86 and also calls to
efi_load_image(), efi_grow_buffer(), efi_get_var() in order to enable
UEFI supported tests for KUT x86 arch.
