Subject: [PATCH v2 0/4] KVM: arm64: Separate the hyp FF-A buffers init from the host
Date: Thu, 27 Feb 2025 18:17:45 +0000	[thread overview]
Message-ID: <20250227181750.3606372-1-sebastianene@google.com> (raw)

Hello,

This moves the initialization of the hypervisor FF-A buffers
away from the host FF-A map calling path. 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.

*** Changelog ***

v1 -> this version:

Split the patch that maps the ff-a buffers of ffa init and introduce
"Move the ffa_to_linux definition to the ffa header".

Thanks,

Sebastian Ene (4):
  KVM: arm64: Use the static initializer for the vesion lock
  KVM: arm64: Move the ffa_to_linux definition to the ffa header
  KVM: arm64: Map the hypervisor FF-A buffers on ffa init
  KVM: arm64: Release the ownership of the hyp rx buffer to Trustzone
