If the hypervisor cannot map the buffers with Trustzone, it rejects any FF-A call when it runs under protected mode. Other than that it moves the definitions of the ffa_to_linux_err map from the arm_ffa driver to the ffa header so that the hyp code can make use of it. Thanks, Sebastian Ene (3): KVM: arm64: Use the static initializer for the vesion lock KVM: arm64: Map the hypervisor FF-A buffers on ffa init KVM: arm64: Release the ownership of the hyp rx buffer to Trustzone arch/arm64/kvm/hyp/nvhe/ffa.c | 56 +++++++++++++------------------ drivers/firmware/arm_ffa/driver.c | 24 ------------- include/linux/arm_ffa.h | 24 +++++++++++++ 3 files changed, 47 insertions(+), 57 deletions(-) -- 2.48.1.658.g4767266eb4-goog
