Subject: Re: [PATCH v5 6/9] vfio/pci: Provide a user-facing name for BAR mappings
Date: Wed, 15 Jul 2026 18:01:24 +0000 [thread overview]

In-Reply-To: <20260715174737.15287-7-matt@ozlabs.org>
> Since converting BAR mmap()s to using DMABUFs, we lose the original
> device path in /proc/<pid>/maps, lsof, etc. Generate a debug-oriented
> synthetic 'filename' based on the cdev, plus BDF, plus resource index.
>
> This applies only to BAR mappings via the VFIO device fd, as
> explicitly-exported DMABUFs are named by userspace via the
> DMA_BUF_SET_NAME ioctl.
