This patch fix the pulse per second output delta between
two synchronized end-points.
Based on Intel Discrete I225 Software User Manual Section
4.2.15 TimeSync Auxiliary Control Register, ST0[Bit 4] and
ST1[Bit 7] must be set to ensure that clock output will be
toggles based on frequency value defined. This is to ensure
that output of the PPS is aligned with the clock.
How to test:
1) Running time synchronization on both end points.
Ex: ptp4l --step_threshold=1 -m -f gPTP.cfg -i <interface name>
2) Configure PPS output using below command for both end-points
Ex: SDP0 on I225 REV4 SKU variant
./testptp -d /dev/ptp0 -L 0,2
./testptp -d /dev/ptp0 -p 1000000000
3) Measure the output using analyzer for both end-points

The Dell Latitude E6430 both with and without the optional NVidia dGPU
has a bug in its ACPI tables which is causing Linux to assign the wrong
ACPI fwnode / companion to the pci_device for the i915 iGPU.
Specifically under the PCI root bridge there are these 2 ACPI Device()s :
Scope (_SB.PCI0)
{
Device (GFX0)
{
Name (_ADR, 0x00020000) // _ADR: Address
}
...
Device (VID)
{
Name (_ADR, 0x00020000) // _ADR: Address
...
Method (_DOS, 1, NotSerialized) // _DOS: Disable Output Switching
{
VDP8 = Arg0
VDP1 (One, VDP8)
}
Method (_DOD, 0, NotSerialized) // _DOD: Display Output Devices
{
...
}
...
}
}
The non-functional GFX0 ACPI device is a problem, because this gets
returned as ACPI companion-device by acpi_find_child_device() for the iGPU.
This is a long standing problem and the i915 driver does use the ACPI
companion for some things, but works fine without it.
However since commit 63f534b8bad9 ("ACPI: PCI: Rework acpi_get_pci_dev()")
acpi_get_pci_dev() relies on the physical-node pointer in the acpi_device
and that is set on the wrong acpi_device because of the wrong
acpi_find_child_device() return. This breaks the ACPI video code,
leading to non working backlight control in some cases.
Add a type.backlight flag, mark ACPI video bus devices with this and make
find_child_checks() return a higher score for children with this flag set,
so that it picks the right companion-device.

Like the Asus Expertbook B2502CBA and various Asus Vivobook laptops,
the Asus Expertbook B2402CBA has an ACPI DSDT table that describes IRQ 1
as ActiveLow while the kernel overrides it to Edge_High. This prevents the
keyboard from working. To fix this issue, add this laptop to the
skip_override_table so that the kernel does not override IRQ 1.

Since commit cbf7827bc5dc ("iommu/s390: Fix potential s390_domain
aperture shrinking") the s390 IOMMU driver uses reserved regions for the
system provided DMA ranges of PCI devices. Previously it reduced the
size of the IOMMU aperture and checked it on each mapping operation.
On current machines the system denies use of DMA addresses below 2^32 for
all PCI devices.
Usually mapping IOVAs in a reserved regions is harmless until a DMA
actually tries to utilize the mapping. However on s390 there is
a virtual PCI device called ISM which is implemented in firmware and
used for cross LPAR communication. Unlike real PCI devices this device
does not use the hardware IOMMU but inspects IOMMU translation tables
directly on IOTLB flush (s390 RPCIT instruction). If it detects IOVA
mappings outside the allowed ranges it goes into an error state. This
error state then causes the device to be unavailable to the KVM guest.
Analysing this we found that vfio_test_domain_fgsp() maps 2 pages at DMA
address 0 irrespective of the IOMMUs reserved regions. Even if usually
harmless this seems wrong in the general case so instead go through the
freshly updated IOVA list and try to find a range that isn't reserved,
and fits 2 pages, is PAGE_SIZE * 2 aligned. If found use that for
testing for fine grained super pages.

After applying an engine reset, on some platforms like Jasperlake, we
occasionally detect that the engine state is not cleared until shortly
after the resume. As we try to resume the engine with volatile internal
state, the first request fails with a spurious CS event (it looks like
it reports a lite-restore to the hung context, instead of the expected
idle->active context switch).

When registering a new DMA MR after selecting the best aligned page size
for it, we iterate over the given sglist to split each entry to smaller,
aligned to the selected page size, DMA blocks.
In given circumstances where the sg entry and page size fit certain
sizes and the sg entry is not aligned to the selected page size, the
total size of the aligned pages we need to cover the sg entry is >= 4GB.
Under this circumstances, while iterating page aligned blocks, the
counter responsible for counting how much we advanced from the start of
the sg entry is overflowed because its type is u32 and we pass 4GB in
size. This can lead to an infinite loop inside the iterator function
because the overflow prevents the counter to be larger
than the size of the sg entry.
Fix the presented problem by changing the advancement condition to
eliminate overflow.

From the get-go, this driver and the ANS syslog have been complaining
about namespace identification. In 6.2-rc1, commit 811f4de0344d ("nvme:
avoid fallback to sequential scan due to transient issues") regressed
the driver by no longer allowing fallback to sequential namespace scans,
leaving us with no namespaces.
It turns out that the real problem is that this controller claiming
NVMe 1.1 compat is treating the CNS field as a binary field, as in NVMe

entity (SecY)
Upon updating MAC security entity (SecY) in hw offload path, the macsec
security association (SA) initialization routine is called. In case of
extended packet number (epn) is enabled the salt and ssci attributes are
retrieved using the MACsec driver rx_sa context which is unavailable when
updating a SecY property such as encoding-sa hence the null dereference.
Fix by using the provided SA to set those attributes.

Currently when macsec offload is set with extended packet number (epn)
enabled, the driver wrongly deduce the short secure channel identifier
(ssci) from the salt instead of the stand alone ssci attribute as it
should, consequently creating a mismatch between the kernel and driver's
ssci values.
Fix by using the ssci value from the relevant attribute.

The post meter table only matches on reg_c5. As such, the inner/outer
match levels are irrelevant for the match critieria. The cited patch only
sets the outer criteria to none, thus setting the inner match level for
encapsulated packets. This caused rules with police action on tunnel
devices to not find an existing flow group for the match criteria, thus
failing to offload the rule.

The current code always does the accounting using the
stats from the parent interface (linked in the rq). This
doesn't work when there are child interfaces configured.
Fix this behavior by always using the stats from the child
interface priv. This will also work for parent only
interfaces: the child (netdev) and parent netdev (rq->netdev)
will point to the same thing.

A user is able to configure an arbitrary number of rx queues when
creating an interface via netlink. This doesn't work for child PKEY
interfaces because the child interface uses the parent receive channels.
Although the child shares the parent's receive channels, the number of
rx queues is important for the channel_stats array: the parent's rx
channel index is used to access the child's channel_stats. So the array
has to be at least as large as the parent's rx queue size for the
counting to work correctly and to prevent out of bound accesses.
This patch checks for the mentioned scenario and returns an error when
trying to create the interface. The error is propagated to the user.

PKEY sub interfaces share the receive queues with the parent interface.
While setting the sub interface queue count is not supported, it is
currently possible to change the number of queues of the parent interface.
Thus we can end up with inconsistent queue sizes between the parent and its
sub interfaces.
This change disallows setting the queue count on the parent interface when
sub interfaces are present.
This is achieved by introducing an explicit reference to the parent netdev
in the mlx5i_priv of the child interface. An additional counter is also
required on the parent side to detect when sub interfaces are attached and
for proper cleanup.
The rtnl lock is taken during the ethtool op and the sub interface
ndo_init/uninit ops. There is no race here around counting the sub
interfaces, reading the sub interfaces and setting the number of
channels. The ASSERT_RTNL was added to document that.

Command may fail while driver is reloading and can't accept FW commands
till command interface is reinitialized. Such command failure is being
logged to command stats. This results in NULL pointer access as command
stats structure is being freed and reallocated during mlx5 devlink
reload (see kernel log below).
Fix it by making command stats statically allocated on driver probe.

When offloading TC NIC rule which has mod_hdr action, the
mod_hdr actions list is freed upon mod_hdr allocation.
In the new format of handling multi table actions and CT in
particular, the mod_hdr actions list is still relevant when
setting the pre and post rules and therefore, freeing the list
may cause adding rules which don't set the FTE_ID.
Therefore, the mod_hdr actions list needs to be kept for the
pre/post flows as well and should be left for these handler to
be freed.
