[Intel-gfx] [PATCH v3 0/6] vfio: Make emulated devices prepared for vfio device cdev

[Yi Liu]

The .bind_iommufd op of vfio emulated devices are either empty or does
nothing. This is different with the vfio physical devices, to add vfio
device cdev, need to make them act the same.

This series first makes the .bind_iommufd op of vfio emulated devices
to create iommufd_access, this introduces a new iommufd API. Then let
the driver that does not provide .bind_iommufd op to use the vfio emulated
iommufd op set. This makes all vfio device drivers have consistent iommufd
operations, which is good for adding new device uAPIs in the device cdev
series.

Change log:

v3:
 - Use iommufd_get_ioas() for ioas get, hence patch 01 is added to modify
   the input parameter of iommufd_get_ioas(). (Jason)
 - Add r-b from Jason and Kevin
 - Add t-b from Terrence Xu

v2: https://lore.kernel.org/kvm/20230316121526.5644-1-yi.l.liu@intel.com/
 - Add r-b from Kevin and Jason
 - Refine patch 01 per comments from Jason and Kevin

v1: https://lore.kernel.org/kvm/20230308131340.459224-1-yi.l.liu@intel.com/

[Intel-gfx] [PATCH v3 2/6] iommufd: Create access in vfio_iommufd_emulated_bind()

[Yi Liu]

From: Nicolin Chen <nicolinc@nvidia.com>

There are needs to created iommufd_access prior to have an IOAS and set
IOAS later. Like the vfio device cdev needs to have an iommufd object
to represent the bond (iommufd_access) and IOAS replacement.

Moves the iommufd_access_create() call into vfio_iommufd_emulated_bind(),
making it symmetric with the __vfio_iommufd_access_destroy() call in the
vfio_iommufd_emulated_unbind(). This means an access is created/destroyed
by the bind()/unbind(), and the vfio_iommufd_emulated_attach_ioas() only
updates the access->ioas pointer.

Since vfio_iommufd_emulated_bind() does not provide ioas_id, drop it from
the argument list of iommufd_access_create(). Instead, add a new access
API iommufd_access_attach() to set the access->ioas pointer. Also, set
vdev->iommufd_attached accordingly, similar to the physical pathway.

Since if ioas is non-null here then we will lose the reference counts
already held.

I'll fix it

the physical path has the same check:

	if (idev->igroup->hwpt != NULL && idev->igroup->hwpt != hwpt) {
		rc = -EINVAL;
		goto err_unlock;
	}

If we change here then that one should be changed too.

No, that one is checking if the another device attached to the same
group is a compatible hwpt so we succeed to attach the new device

[Intel-gfx] [PATCH v3 3/6] vfio-iommufd: No need to record iommufd_ctx in vfio_device

[Yi Liu]

iommufd_ctx is stored in vfio_device for emulated devices per bind_iommufd.
However, as iommufd_access is created in bind, no more need to stored it
since iommufd_access implicitly stores it.

[Intel-gfx] [PATCH v3 5/6] vfio/mdev: Uses the vfio emulated iommufd ops set in the mdev sample drivers

This harmonizes the no-DMA devices (the vfio-mdev sample drivers) with
the emulated devices (gvt-g, vfio-ap etc.). It makes it easier to add
BIND_IOMMUFD user interface which requires to return an iommufd ID to
represent the device/iommufd bond.

This runs well with iommufd selftest on x86 and QEMU sanity on
ARM64, applying nesting series on top of this and cdev series:
