Hi Linus,
The following changes since commit b401b621758e46812da61fa58a67c3fd8d91de0d:
Linux 6.8-rc5 (2024-02-18 12:56:25 -0800)
are available in the Git repository at:
https://github.com/awilliam/linux-vfio.git tags/vfio-v6.9-rc1
for you to fetch changes up to 7447d911af699a15f8d050dfcb7c680a86f87012:
vfio/fsl-mc: Block calling interrupt handler without trigger (2024-03-11 13:08:52 -0600)
A couple minor additional notes, first you'll see a trivial conflict in
MAINTAINERS as reported and properly resolved by Stephen here:
https://lore.kernel.org/all/[email protected]/
Second, just for awareness, this includes a merge from the kvmarm tree
for a dependency on the new vma VM_ALLOW_ANY_UNCACHED flag which is
further described in Oliver's merge (and of course the individual
commits):
https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git/commit/?h=kvmarm-6.9&id=9bd8d7df1971c2ebdcaf4526cf7a3f4ea38d0ede
Thanks,

VFIO updates for v6.9-rc1
- Add warning in unlikely case that device is not captured with
driver_override. (Kunwu Chan)
- Error handling improvements in mlx5-vfio-pci to detect firmware
tracking object error states, logging of firmware error syndrom,
and releasing of firmware resources in aborted migration sequence.
(Yishai Hadas)
- Correct an un-alphabetized VFIO MAINTAINERS entry.
(Alex Williamson)
- Make the mdev_bus_type const and also make the class struct const
for a couple of the vfio-mdev sample drivers. (Ricardo B. Marliere)
- Addition of a new vfio-pci variant driver for the GPU of NVIDIA's
Grace-Hopper superchip. During initialization of the chip-to-chip
interconnect in this hardware module, the PCI BARs of the device
become unused in favor of a faster, coherent mechanism for exposing
device memory. This driver primarily changes the VFIO
representation of the device to masquerade this coherent aperture
to replace the physical PCI BARs for userspace drivers. This also
incorporates use of a new vma flag allowing KVM to use write
combining attributes for uncached device memory. (Ankit Agrawal)
- Reset fixes and cleanups for the pds-vfio-pci driver. Save and
restore files were previously leaked if the device didn't pass
through an error state, this is resolved and later re-fixed to
prevent access to the now freed files. Reset handling is also
refactored to remove the complicated deferred reset mechanism.
(Brett Creeley)
- Remove some references to pl330 in the vfio-platform amba
driver. (Geert Uytterhoeven)
- Remove twice redundant and ugly code to unpin incidental pins
of the zero-page. (Alex Williamson)
- Deferred reset logic is also removed from the hisi-acc-vfio-pci
driver as a simplification. (Shameer Kolothum)
- Enforce that mlx5-vfio-pci devices must support PRE_COPY and
remove resulting unnecessary code. There is no device firmware
that has been available publicly without this support.
(Yishai Hadas)
- Switch over to using the .remove_new callback for vfio-platform
in support of the broader transition for a void remove function.
(Uwe Kleine-König)
- Resolve multiple issues in interrupt code for VFIO bus drivers
that allow calling eventfd_signal() on a NULL context. This
also remove a potential race in INTx setup on certain hardware
for vfio-pci, races with various mechanisms to mask INTx, and
leaked virqfds in vfio-platform. (Alex Williamson)
