Subject: [PATCH 14/15] hw/virtio/vhost: Replace legacy cpu_physical_memory_*map() calls
Date: Mon, 29 Sep 2025 20:32:53 +0200 [thread overview]
Message-ID: <20250929183254.85478-15-philmd@linaro.org> (raw)
In-Reply-To: <20250929183254.85478-1-philmd@linaro.org>
Use VirtIODevice::dma_as address space to convert the legacy
cpu_physical_memory_[un]map() calls to address_space_[un]map().
Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
