Subject: [PATCH] vfio/mdev: make VFIO_MDEV user-visible in Kconfig
Date: Thu, 5 Mar 2026 15:35:26 -0800 [thread overview]
Message-ID: <20260305233526.32607-1-jp.kobryn@linux.dev> (raw)
From: JP Kobryn <jp.kobryn@linux.dev>
VFIO_MDEV is currently hidden and only enabled via select by in-tree
consumers. Out-of-tree drivers such as the NVIDIA vGPU rely on the mdev
framework but have no way to trigger its selection.
Add a description and help text to make VFIO_MDEV visible and directly
selectable.
