Subject: [PATCH v2 16/17] hw/virtio/vhost: Replace legacy cpu_physical_memory_*map() calls
Date: Tue, 30 Sep 2025 06:13:24 +0200 [thread overview]
Message-ID: <20250930041326.6448-17-philmd@linaro.org> (raw)
In-Reply-To: <20250930041326.6448-1-philmd@linaro.org>
Use VirtIODevice::dma_as address space to convert the legacy
cpu_physical_memory_[un]map() calls to address_space_[un]map().
