Same Trusted Application (TA) can be loaded in multiple TEE contexts.
If it is a single instance TA, the TA should not get unloaded from AMD
Secure Processor, while it is still in use in another TEE context.
Therefore reference count TA and unload it when the count becomes zero.
Fixes: 757cc3e9ff1d ("tee: add AMD-TEE driver")

Our driver supports overlay planes, and as expected, some userspace
compositor takes advantage of these features. If the userspace is not
enabling the cursor, they can use multiple planes as they please.
Nevertheless, we start to have constraints when userspace tries to
enable hardware cursor with various planes. Basically, we cannot draw
the cursor at the same size and position on two separated pipes since it
uses extra bandwidth and DML only run with one cursor.
For those reasons, when we enable hardware cursor and multiple planes,
our driver should accept variations like the ones described below:
+-------------+ +--------------+
| +---------+ | | |
| |Primary | | | Primary |
| | | | | Overlay |
| +---------+ | | |
|Overlay | | |
+-------------+ +--------------+
In this scenario, we can have the desktop UI in the overlay and some
other framebuffer attached to the primary plane (e.g., video). However,
userspace needs to obey some rules and avoid scenarios like the ones
described below (when enabling hw cursor):
+--------+
|Overlay |
+-------------+ +-----+-------+ +-| |--+
| +--------+ | +--------+ | | +--------+ |
| |Overlay | | |Overlay | | | |
| | | | | | | | |
| +--------+ | +--------+ | | |
| Primary | | Primary | | Primary |
+-------------+ +-------------+ +-------------+
+-------------+ +-------------+
| +--------+ | Primary |
| |Overlay | | |
| | | | |
| +--------+ | +--------+ |
| Primary | | |Overlay | |
+-------------+ +-| |--+
+--------+
If the userspace violates some of the above scenarios, our driver needs
to reject the commit; otherwise, we can have unexpected behavior. Since
we don't have a proper driver validation for the above case, we can see
some problems like a duplicate cursor in applications that use multiple
planes. This commit fixes the cursor issue and others by adding adequate
verification for multiple planes.
Change since V1 (Harry and Sean):
- Remove cursor verification from the equation.

particular support for attaching to already running remote processors

When switching virtio_pci_modern to use a helper for mappings we lost an
__iomem tag. We should restore it.
However, virtio_pci_modern is playing tricks by hiding an iomem pointer
in a regular vq->priv pointer. Which is okay as long as it's
all contained within a single file, but we need to __force cast
the value otherwise we'll get sparse warnings.

Nothing can stop a host from submitting invalid commands. The target
just needs to respond with an appropriate status, but that's not a

reset_work() in nvme-pci may hang forever in the following scenario:
1) A reset caused by a command timeout occurs due to a controller being
temporarily irresponsive.
2) nvme_reset_work() restarts admin queue at nvme_alloc_admin_tags(). At
the same time, a user-submitted admin command is queued and waiting
for completion. Then, reset_work() changes its state to CONNECTING,
and submits an identify command.
3) However, the controller does still not respond to any command,
causing a timeout being fired at the user-submitted command.
Unfortunately, nvme_timeout() does not see the completion on cq, and
any timeout that takes place under CONNECTING state causes a
controller shutdown.
4) Normally, the identify command in reset_work() would be canceled with
SC_HOST_ABORTED by nvme_dev_disable(), then reset_work can tear down
the controller accordingly. But the controller happens to return
online and respond the identify command before nvme_dev_disable()
should have been reaped it off.
5) reset_work() continues to setup_io_queues() as it observes no error
in init_identify(). However, the admin queue has already been
quiesced in dev_disable(). Thus, any following commands would be
blocked forever in blk_execute_rq().
This can be fixed by restricting usercmd commands when controller is not
in a LIVE state in nvme_queue_rq(), as what has been done previously in
fabrics.
```
nvme_reset_work(): |
nvme_alloc_admin_tags() |
| nvme_submit_user_cmd():
nvme_init_identify(): | ...
__nvme_submit_sync_cmd(): |
... | ...
---------------------------------------> nvme_timeout():
(Controller starts reponding commands) | nvme_dev_disable(, true):
nvme_setup_io_queues(): |
__nvme_submit_sync_cmd(): |
(hung in blk_execute_rq |
since run_hw_queue sees |
queue quiesced) |
