Subject: [PATCH v2 0/2] KVM: arm64: Support FF-A direct messaging interfaces
Date: Thu, 30 Oct 2025 15:49:15 +0000 [thread overview]
Message-ID: <20251030-host-direct-messages-v2-0-9f27cef36730@google.com> (raw)
Support FFA_MSG_SEND_DIRECT_REQ unconditionally.
Support FFA_MSG_SEND_DIRECT_REQ2 if hypervisor negotiated version 1.2+.
The second patch was part of a previous patch set [0] but was dropped
since the use case was unclear. A clear use case has now appeared [1].
Tested by booting Android under QEMU.
Best Regards,
Per
