From 762c85543948bf1f7838d663995648635d3f4b92 Mon Sep 17 00:00:00 2001 From: Cédric Le Goater Date: Mon, 1 Sep 2025 08:46:30 +0200 Subject: vfio: Remove 'vfio-platform' MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The VFIO_PLATFORM device type has been deprecated in the QEMU 10.0 timeframe. All dependent devices have been removed. Now remove the core vfio platform framework. Rename VFIO_DEVICE_TYPE_PLATFORM enum to VFIO_DEVICE_TYPE_UNUSED to maintain the same index for the CCW and AP VFIO device types.
