[PATCH v9 6/6] KVM: arm64: Bump the supported version of FF-A to 1.2
Posted by Per Larsen via B4 Relay 2 months ago
From: Per Larsen <perlarsen@google.com>

FF-A version 1.2 introduces the DIRECT_REQ2 ABI. Bump the FF-A version
preferred by the hypervisor to enable implementation of the 1.2-only
FFA_MSG_SEND_DIRECT_REQ2 and FFA_MSG_SEND_RESP2 messaging interfaces.
