Subject: [PATCH v9 06/11] KVM: selftests: Explicitly ucall pool from shared memory
Date: Thu, 22 Feb 2024 16:42:53 -0800 [thread overview]
Message-ID: <20240223004258.3104051-7-seanjc@google.com> (raw)
In-Reply-To: <20240223004258.3104051-1-seanjc@google.com>
From: Peter Gonda <pgonda@google.com>
Allocate the common ucall pool using vm_vaddr_alloc_shared() so that the
ucall structures will be placed in shared (unencrypted) memory for VMs
with support for protected (encrypted) memory, e.g. x86's SEV.
