When calling arch_sync_dma, we need to pass it the memory that's
actually being used for dma. When using swiotlb bounce buffers, this is
the bounce buffer. Move arch_sync_dma into the __iommu_dma_map_swiotlb
helper, so it can use the bounce buffer address if necessary.
Now that iommu_dma_map_sg delegates to a function which takes care of
architectural syncing in the untrusted device case, the call to
iommu_dma_sync_sg_for_device can be moved so it only occurs for trusted
devices. Doing the sync for untrusted devices before mapping never
really worked, since it needs to be able to target swiotlb buffers.
This also moves the architectural sync to before the call to
__iommu_dma_map, to guarantee that untrusted devices can't see stale
data they shouldn't see.

The is_swiotlb_buffer function takes the physical address of the swiotlb
buffer, not the physical address of the original buffer. The sglist
contains the physical addresses of the original buffer, so for the
sync_sg functions to work properly when a bounce buffer might have been
used, we need to use iommu_iova_to_phys to look up the physical address.
This is what sync_single does, so call that function on each sglist
segment.
The previous code mostly worked because swiotlb does the transfer on map
and unmap. However, any callers which use DMA_ATTR_SKIP_CPU_SYNC with
sglists or which call sync_sg would not have had anything copied to the
bounce buffer.

When EEE support was added to the 28nm EPHY it was assumed that it would
be able to support the standard clause 45 over clause 22 register access
method. It turns out that the PHY does not support that, which is the
very reason for using the indirect shadow mode 2 bank 3 access method.
Implement {read,write}_mmd to allow the standard PHY library routines
pertaining to EEE querying and configuration to work correctly on these
PHYs. This forces us to implement a __phy_set_clr_bits() function that
does not grab the MDIO bus lock since the PHY driver's {read,write}_mmd
functions are always called with that lock held.

Currently, the firmware compatible features are enabled in PF driver
initialization process, but they are not disabled in PF driver
deinitialization process and firmware keeps these features in enabled
status.
In this case, if load an old PF driver (for example, in VM) which not
support the firmware compatible features, firmware will still send mailbox
message to PF when link status changed and PF will print
"un-supported mailbox message, code = 201".
To fix this problem, disable these firmware compatible features in PF
driver deinitialization process.

Currently, the rx vlan filter will always be disabled before selftest and
be enabled after selftest as the rx vlan filter feature is fixed on in
old device earlier than V3.
However, this feature is not fixed in some new devices and it can be
disabled by user. In this case, it is wrong if rx vlan filter is enabled
after selftest. So fix it.

For destroy mqprio is irreversible in stack, so it's unnecessary
to rollback the tc configuration when destroy mqprio failed.
Otherwise, it may cause the configuration being inconsistent
between driver and netstack.
As the failure is usually caused by reset, and the driver will
restore the configuration after reset, so it can keep the
configuration being consistent between driver and hardware.

driver doesn't report the queue count and offset for disabled

The ixgbe driver currently generates a NULL pointer dereference with
some machine (online cpus < 63). This is due to the fact that the
maximum value of num_xdp_queues is nr_cpu_ids. Code is in
"ixgbe_set_rss_queues"".
Here's how the problem repeats itself:
Some machine (online cpus < 63), And user set num_queues to 63 through
ethtool. Code is in the "ixgbe_set_channels",
adapter->ring_feature[RING_F_FDIR].limit = count;
It becomes 63.
When user use xdp, "ixgbe_set_rss_queues" will set queues num.
adapter->num_rx_queues = rss_i;
adapter->num_tx_queues = rss_i;
adapter->num_xdp_queues = ixgbe_xdp_queues(adapter);
And rss_i's value is from
f = &adapter->ring_feature[RING_F_FDIR];
rss_i = f->indices = f->limit;
So "num_rx_queues" > "num_xdp_queues", when run to "ixgbe_xdp_setup",
for (i = 0; i < adapter->num_rx_queues; i++)
if (adapter->xdp_ring[i]->xsk_umem)
It leads to panic.

In wait for CS IOCTL code, the driver resets the incoming args structure
before returning to the user, regardless of the return value of the
IOCTL.
In case the IOCTL returns EINTR, resetting the args will result in error
in case the userspace will repeat the ioctl call immediately (which is
the behavior in the hl-thunk userspace library).
The solution is to reset the args only if the driver returns success (0)
as a return value for the IOCTL.

Similar to DRM_VMW_EVENT_FENCE_SIGNALED. Sends a pollable event
to the DRM file descriptor when a fence on a specific ring is
signaled.
One difference is the event is not exposed via the UAPI -- this is
because host responses are on a shared memory buffer of type
BLOB_MEM_GUEST [this is the common way to receive responses with
virtgpu]. As such, there is no context specific read(..)
implementation either -- just a poll(..) implementation.

For the Sommelier guest Wayland proxy, it's desirable for the
DRM fd to be pollable in response to an host compositor event.
This can also be used by the 3D driver to poll events on a CPU
timeline.
This enables the DRM fd associated with a particular 3D context
to be polled independent of KMS events. The parameter
VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK specifies the pollable
rings.

The plumbing is all here to do this. Since we always use the
default fence context when allocating a fence, this makes no
functional difference.
We can't process just the largest fence id anymore, since it's
it's associated with different timelines. It's fine for fence_id
260 to signal before 259. As such, process each fence_id

These were defined in the previous commit. We'll need these
parameters when allocating a dma_fence. The use case for this
is multiple synchronizations timelines.
The maximum number of timelines per 3D instance will be 32. Usually,
only 2 are needed -- one for CPU commands, and another for GPU
commands.
As such, we'll need to specify these parameters when allocating a

Each fence should be associated with a [fence ID, fence_context,
seqno]. The seqno number is just the fence id.
To get the fence context, we add the ring_idx to the 3D context's
base_fence_ctx. The ring_idx is between 0 and 31, inclusive.
Each 3D context will have it's own base_fence_ctx. The ring_idx will
be emitted to host userspace, when emit_fence_info is true.

This implements the context initialization ioctl. A list of params
is passed in by userspace, and kernel driver validates them. The
only currently supported param is VIRTGPU_CONTEXT_PARAM_CAPSET_ID.
If the context has already been initialized, -EEXIST is returned.
This happens after Linux userspace does dumb_create + followed by
opening the Mesa virgl driver with the same virtgpu instance.
However, for most applications, 3D contexts will be explicitly
initialized when the feature is available.

The valid capability IDs are between 1 to 63, and defined in the
virtio gpu spec. This is used for error checking the subsequent
patches. We're currently only using 2 capability IDs, so this
should be plenty for the immediate future.
