vfio/mtty: Enable migration support (2023-10-24 15:03:10 -0600)
----------------------------------------------------------------
VFIO updates for v6.7
- Add support for "chunk mode" in the mlx5-vfio-pci variant driver,
which allows both larger device image sizes for migration, beyond
the previous 4GB limit, and also read-ahead support for improved
migration performance. (Yishai Hadas)
- A new bus master control interface for the CDX bus driver where
there is no in-band mechanism to toggle device DMA as there is
through config space on PCI devices. (Nipun Gupta)
- Add explicit alignment directives to vfio data structures to
reduce the chance of breaking 32-bit userspace. In most cases
this is transparent and the remaining cases where data structures
are padded work within the existing rules for extending data
structures within vfio. (Stefan Hajnoczi)
- Resolve a bug in the cdx bus driver noted when compiled with clang
where missing parenthesis result in the wrong operation.
(Nathan Chancellor)
- Resolve errors reported by smatch for a function when dealing
with invalid inputs. (Alex Williamson)
- Add migration support to the mtty vfio/mdev sample driver for
testing and integration purposes, allowing CI of migration without
specific hardware requirements. Also resolve many of the short-
comings of this driver relative to implementation of the vfio
interrupt ioctl along the way. (Alex Williamson)
