When unbinding the firmware device we need to make sure it has no
consumers left. Otherwise we'd leave them with a firmware handle
pointing at freed memory.
Keep a reference count of all consumers and make sure they all finished
unbinding before we do.

There's nothing special about zram and lzo. It works just fine without it, so
as long as at least one of the other supported compression algorithms is
selected.
Additionally, drop the explicit dependency from CRYPTO, as it's implied by the
selection of the algorithms themselves.

The queues assigned to a matrix mediated device are currently reset when:
* The VFIO_DEVICE_RESET ioctl is invoked
* The mdev fd is closed by userspace (QEMU)
* The mdev is removed from sysfs.
Immediately after the reset of a queue, a call is made to disable
interrupts for the queue. This is
This patch refactors the vfio_ap device driver to use the AP bus's
ap_get_qdev() function to retrieve the vfio_ap_queue struct containing
information about a queue that is bound to the vfio_ap device driver.
The bus's ap_get_qdev() function retrieves the queue device from a
hashtable keyed by
Introduces a new driver callback to prevent a root user from unbinding
an AP queue from its device driver if the queue is in use. The callback
will be invoked whenever a change to the AP bus's sysfs apmask or aqmask
attributes would result in one or more AP queues being removed from its
driver. If

The motivation for config change notification is to enable the vfio_ap
device driver to handle hot plug/unplug of AP queues for a KVM guest as a
bulk operation. For example, if a new APID is dynamically assigned to the
host configuration, then a queue device will be created for each APQN that
can
Let's hot plug/unplug adapters, domains and control domains assigned to or
unassigned from an AP matrix mdev device while it is in use by a guest per
the following:
* Hot plug AP adapter:
When the APID of an adapter is assigned to a matrix mdev in use by a KVM
guest, the adapter will be hot
This patch intruduces an extension to the ap bus to notify device drivers
when the host AP configuration changes - i.e., adapters, domains or
control domains are added or removed. To that end, two new callbacks are
introduced for AP device drivers:
void (*on_config_changed)(struct
The APCB is a field within the CRYCB that provides the AP configuration
to a KVM guest. Let's introduce a shadow copy of the KVM guest's APCB and
maintain it for the lifespan of the guest.

In response to the probe or remove of a queue device, if a KVM guest is
using the matrix mdev to which the APQN of the queue device is assigned,
the vfio_ap device driver must respond accordingly. In an ideal world, the
queue device being probed would be hot plugged into the guest. Likewise,

Let's implement the callback to indicate when an APQN

The current implementation does not allow assignment of an AP adapter or
domain to an mdev device if each APQN resulting from the assignment
does not reference an AP queue device that is bound to the vfio_ap device
driver. This patch allows assignment of AP resources to the matrix mdev as

Let's create links between each queue device bound to the vfio_ap device
driver and the matrix mdev to which the queue is assigned. The idea is to
facilitate efficient retrieval of the objects representing the queue
devices and matrix mdevs as well as to verify that a queue assigned to
a matrix
The current design for AP pass-through does not support making dynamic
changes to the AP matrix of a running guest resulting in a few
deficiencies this patch series is intended to mitigate:
1. Adapters, domains and control domains can not be added to or removed
from a running guest. In order
The matrix of adapters and domains configured in a guest's APCB may
differ from the matrix of adapters and domains assigned to the matrix mdev,
so this patch introduces a sysfs attribute to display the matrix of a guest
using the matrix mdev. For a matrix mdev denoted by $uuid, the crycb for a
Implements the driver callback invoked by the AP bus when the AP bus
scan has completed. Since this callback is invoked after binding the newly
added devices to their respective device drivers, the vfio_ap driver will
attempt to hot plug the adapters, domains and control domains into each
guest

According to the documentation from NXP, the i.MX8M Nano has a
Vivante GC7000 Ultra Lite as its GPU core.
With this patch, the Etnaviv driver presents the GPU as:
etnaviv-gpu 3800.gpu: model: GC7000, revision: 6203
It uses the GPCV2 controller to enable the power domain for the GPU.

No objections from me. And, I like that it could
