The commit 23c0e5a16bcc ("ixgbe: Add link management support for E610
device") introduced incorrect media type detection for E610 device. It
reproduces when advertised speed is modified after driver reload. Clear
the previous outdated PHY type high value.
Reproduction steps:
modprobe ixgbe
ethtool -s eth0 advertise 0x1000000000000
modprobe -r ixgbe
modprobe ixgbe
ethtool -s eth0 advertise 0x1000000000000
Result before the fix:
netlink error: link settings update failed
netlink error: Invalid argument
Result after the fix:
No output error

Starting from Meteor Lake, the Kumeran interface between the integrated
MAC and the I219 PHY works at a different frequency. This causes sporadic
MDI errors when accessing the PHY, and in rare circumstances could lead
to packet corruption.
To overcome this, introduce minor changes to the Kumeran idle
state (K1) parameters during device initialization. Hardware reset
reverts this configuration, therefore it needs to be applied in a few
places.

Fixes TX frame drops in AF_XDP zero copy mode when budget < 4.
xsk_tx_peek_desc() consumed TX frame and it was ignored because of
low budget. Not even AF_XDP completion was done for dropped frames.
It can be reproduced on i226 by sending 100000x 60 B frames with
launch time set to minimal IPG (672 ns between starts of frames)
on 1Gbit/s. Always 1026 frames are not sent and are missing a
completion.

In commit b65969856d4f ("igc: Link queues to NAPI instances"), the XSK
queues were incorrectly unmapped from their NAPI instances. After
discussion on the mailing list and the introduction of a test to codify
the expected behavior, we can see that the unmapping causes the
check_xsk test to fail:
NETIF=enp86s0 ./tools/testing/selftests/drivers/net/queues.py
[...]
# Check| ksft_eq(q.get('xsk', None), {},
# Check failed None != {} xsk attr on queue we configured
not ok 4 queues.check_xsk
After this commit, the test passes:
ok 4 queues.check_xsk
Note that the test itself is only in net-next, so I tested this change
by applying it to my local net-next tree, booting, and running the test.

Merge an ACPI backlight (video) driver fix, an ACPI platform-profile
driver optimization, and a miscellaneous ACPI-related cleanup for
6.15-rc1:
- Make the ACPI backlight driver handle fetching EDID as
ACPI_TYPE_PACKAGE which is not specification-compliant, but
has been encountered in the field (Gergo Koteles).
- Simplify the aggregation of choices in the ACPI platform-profile
driver which has become possible after recent modifications of that

The lookup table forces the use of the "pinctrl-bcm2835" GPIO chip
provider and essentially assumes that there is going to be such a
provider, and if not, we will fail to set-up the SPI device.
While this is true on Raspberry Pi based systems (2835/36/37, 2711,
2712), this is not true on 7712/77122 Broadcom STB systems which use the
SPI driver, but not the GPIO driver.
There used to be an early check:
chip = gpiochip_find("pinctrl-bcm2835", chip_match_name);
if (!chip)
return 0;
which would accomplish that nicely, bring something similar back by
checking for the compatible strings matched by the pinctrl-bcm2835.c
driver, if there is no Device Tree node matching those compatible
strings, then we won't find any GPIO provider registered by the
"pinctrl-bcm2835" driver.

Pull iommufd updates from Jason Gunthorpe:
"Two significant new items:
- Allow reporting IOMMU HW events to userspace when the events are
clearly linked to a device.
This is linked to the VIOMMU object and is intended to be used by a
VMM to forward HW events to the virtual machine as part of
emulating a vIOMMU. ARM SMMUv3 is the first driver to use this
mechanism. Like the existing fault events the data is delivered
through a simple FD returning event records on read().
- PASID support in VFIO.
The "Process Address Space ID" is a PCI feature that allows the
device to tag all PCI DMA operations with an ID. The IOMMU will
then use the ID to select a unique translation for those DMAs. This
is part of Intel's vIOMMU support as VT-D HW requires the
hypervisor to manage each PASID entry.
The support is generic so any VFIO user could attach any
translation to a PASID, and the support should work on ARM SMMUv3
as well. AMD requires additional driver work.
Some minor updates, along with fixes:
- Prevent using nested parents with fault's, no driver support today
- Put a single "cookie_type" value in the iommu_domain to indicate
what owns the various opaque owner fields"

The vfpriv->ctx_id is always initialized to a non-zero value. Check whether
context was created before attaching GEM to this context ID. This left
unnoticed previously because host silently skips attachment if context
doesn't exist, still we shouldn't do that for consistency.

Since acpi_processor_notify() can be called before registering a cpufreq
driver or even in cases when a cpufreq driver is not registered at all,
cpufreq_update_limits() needs to check if a cpufreq driver is present
and prevent it from being unregistered.
For this purpose, make it call cpufreq_cpu_get() to obtain a cpufreq
policy pointer for the given CPU and reference count the corresponding
policy object, if present.

Pull MM updates from Andrew Morton:
- The series "Enable strict percpu address space checks" from Uros
Bizjak uses x86 named address space qualifiers to provide
compile-time checking of percpu area accesses.
This has caused a small amount of fallout - two or three issues were
reported. In all cases the calling code was found to be incorrect.
- The series "Some cleanup for memcg" from Chen Ridong implements some
relatively monir cleanups for the memcontrol code.
- The series "mm: fixes for device-exclusive entries (hmm)" from David
Hildenbrand fixes a boatload of issues which David found then using
device-exclusive PTE entries when THP is enabled. More work is
needed, but this makes thins better - our own HMM selftests now
succeed.
- The series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed
remove the z3fold and zbud implementations. They have been deprecated
for half a year and nobody has complained.
- The series "mm: further simplify VMA merge operation" from Lorenzo
Stoakes implements numerous simplifications in this area. No runtime
effects are anticipated.
- The series "mm/madvise: remove redundant mmap_lock operations from
process_madvise()" from SeongJae Park rationalizes the locking in the
madvise() implementation. Performance gains of 20-25% were observed
in one MADV_DONTNEED microbenchmark.

Stoakes changes the interaction between framebuffer deferred-io and
core MM. No functional changes are anticipated - this is preparatory
work for the future removal of page structure fields.
- The series "mm/damon: add support for hugepage_size DAMOS filter"
from Usama Arif adds a DAMOS filter which permits the filtering by
huge page sizes.
- The series "mm: permit guard regions for file-backed/shmem mappings"
from Lorenzo Stoakes extends the guard region feature from its
present "anon mappings only" state. The feature now covers shmem and
file-backed mappings.
- The series "mm: batched unmap lazyfree large folios during
reclamation" from Barry Song cleans up and speeds up the unmapping
for pte-mapped large folios.
- The series "reimplement per-vma lock as a refcount" from Suren
Baghdasaryan puts the vm_lock back into the vma. Our reasons for
pulling it out were largely bogus and that change made the code more
messy. This patchset provides small (0-10%) improvements on one

powerpc, sparc and x86 lazy MMU implementations. Ryan did this in
preparation for implementing lazy mmu mode for arm64 to optimize
vmalloc.
- The series "mm/page_alloc: Some clarifications for migratetype

Butt cleans up the page_counter code and fixes a size increase which
we accidentally added late last year.

many threads should be used to allocate huge pages" from Thomas
Prescher does that. It allows the careful operator to significantly
reduce boot time by tuning the parallalization of huge page
initialization.
- The series "Fix calculations in trace_balance_dirty_pages() for cgwb"
from Tang Yizhou fixes the tracing output from the dirty page
balancing code.
- The series "mm/damon: make allow filters after reject filters useful

reject filters. Behaviour is made more consistent and the documention
is updated accordingly.
- The series "Switch zswap to object read/write APIs" from Yosry Ahmed
updates zswap to the new object read/write APIs and thus permits the
removal of some legacy code from zpool and zsmalloc.
- The series "Some trivial cleanups for shmem" from Baolin Wang does as

nvme_map_user_request() is called from both nvme_submit_user_cmd() and
nvme_uring_cmd_io(). But the ioucmd branch is only applicable to
nvme_uring_cmd_io(). Move it to nvme_uring_cmd_io() and just pass the
resulting iov_iter to nvme_map_user_request().
For NVMe passthru operations with fixed buffers, the fixed buffer lookup
happens in io_uring_cmd_import_fixed(). But nvme_uring_cmd_io() can
return -EAGAIN first from nvme_alloc_user_request() if all tags in the
tag set are in use. This ordering difference is observable when using
UBLK_U_IO_{,UN}REGISTER_IO_BUF SQEs to modify the fixed buffer table. If
the NVMe passthru operation is followed by UBLK_U_IO_UNREGISTER_IO_BUF
to unregister the fixed buffer and the NVMe passthru goes async, the
fixed buffer lookup will fail because it happens after the unregister.
Userspace should not depend on the order in which io_uring issues SQEs
submitted in parallel, but it may try submitting the SQEs together and
fall back on a slow path if the fixed buffer lookup fails. To make the
fast path more likely, do the import before nvme_alloc_user_request().

Instead of mapping and unmapping the completion queues memory to the
host PCI address space whenever nvmet_pci_epf_cq_work() is called, map
a completion queue to the host PCI address space when the completion
queue is created with nvmet_pci_epf_create_cq() and unmap it when the
completion queue is deleted with nvmet_pci_epf_delete_cq().
This removes the completion queue mapping/unmapping from
nvmet_pci_epf_cq_work() and significantly increases performance. For
a single job 4K random read QD=1 workload, the IOPS is increased from
23 KIOPS to 25 KIOPS. Some significant throughput increasde for high
queue depth and large IOs workloads can also be seen.
Since the functions nvmet_pci_epf_map_queue() and
nvmet_pci_epf_unmap_queue() are called respectively only from
nvmet_pci_epf_create_cq() and nvmet_pci_epf_delete_cq(), these functions
are removed and open-coded in their respective call sites.

An erroneous message is written to the kernel log when either of the
following actions are taken by a user:
1. Assign an adapter or domain to a vfio_ap mediated device via its sysfs
assign_adapter or assign_domain attributes that would result in one or
more AP queues being assigned that are already assigned to a different
mediated device. Sharing of queues between mdevs is not allowed.
2. Reserve an adapter or domain for the host device driver via the AP bus
driver's sysfs apmask or aqmask attribute that would result in providing
host access to an AP queue that is in use by a vfio_ap mediated device.
Reserving a queue for a host driver that is in use by an mdev is not
allowed.
In both cases, the assignment will return an error; however, a message like
the following is written to the kernel log:
vfio_ap_mdev e1839397-51a0-4e3c-91e0-c3b9c3d3047d: Userspace may not
re-assign queue 00.0028 already assigned to \
e1839397-51a0-4e3c-91e0-c3b9c3d3047d
Notice the mdev reporting the error is the same as the mdev identified
in the message as the one to which the queue is being assigned.
It is perfectly okay to assign a queue to an mdev to which it is
already assigned; the assignment is simply ignored by the vfio_ap device
driver.
This patch logs more descriptive and accurate messages for both 1 and 2
above to the kernel log:
Example for 1:
vfio_ap_mdev 0fe903a0-a323-44db-9daf-134c68627d61: Userspace may not assign
queue 00.0033 to mdev: already assigned to \
62177883-f1bb-47f0-914d-32a22e3a8804
Example for 2:
vfio_ap_mdev 62177883-f1bb-47f0-914d-32a22e3a8804: Can not reserve queue

During the v6.14-rc cycles, there has been an issue with syscons which
prevented TI chipid controller to probe, itself preventing the only DMA
engine on AM62A with the memcpy capability to probe, which is needed for
the SPI controller to work in its most efficient configuration.
The SPI controller on AM62A can be used in DAC and INDAC mode, which are
some kind of direct mapping vs. CPU-controlled SPI operations,
respectively. However, because of hardware constraints (some kind of
request line not being driven), INDAC mode cannot leverage DMA without
risking to underflow the SPI FIFO. This mode costs a lot of CPU
cycles. On the other side however, DAC mode can be used with and without
DMA support, but in practice, DMA transfers are way more efficient
because of the burst capabilities that the CPU does not have.
As a result, in terms of read throughput, using a Winbond chip in 1-8-8
SDR mode, we get:
- 3.5MiB/s in DAC mode without DMA
- 9.0MiB/s in INDAC mode (CPU more busy)
- a fluctuating 9 to 12MiB/s in DAC mode with DMA (a constant 14.5MiB/s
without CPUfreq)
The reason for the patch that is being reverted is that because of the
syscon issue, we were using a very un-efficient DAC configuration (no
DMA), but since:
commit 5728c92ae112 ("mfd: syscon: Restore device_node_to_regmap() for non-syscon nodes")
the probing of the DMA controller has been fixed, and the performances are
back to normal, so we can safely revert this commit.
This is a revert of:

After resume/online turbo limit ratio (TRL) is restored partially if
the admin explicitly changed TRL from user space.
A hash table is used to store SST mail box and MSR settings when modified
to restore those settings after resume or online. This uses a struct
isst_cmd field "data" to store these settings. This is a 64 bit field.
But isst_store_new_cmd() is only assigning as u32. This results in
truncation of 32 bits.
Change the argument to u64 from u32.

T495, T495s, and E560 laptops have the FANG+FANW ACPI methods
(therefore fang_handle and fanw_handle are not NULL) but they do not
actually work, which results in a "No such device or address" error.
The DSDT table code for the FANG+FANW methods doesn't seem to do
anything special regarding the fan being secondary. The bug was
introduced in commit 57d0557dfa49 ("platform/x86: thinkpad_acpi: Add
Thinkpad Edge E531 fan support"), which added a new fan control method
via the FANG+FANW ACPI methods.
Add a quirk for T495, T495s, and E560 to avoid the FANG+FANW methods.
Fan access and control is restored after forcing the legacy non-ACPI
fan control method by setting both fang_handle and fanw_handle to NULL.

Some subdrivers make use of the global reference tpacpi_pdev during
initialization, which is called from the platform driver's probe.
However, after the commit 38b9ab80db31 ("platform/x86: thinkpad_acpi:
Move subdriver initialization to tpacpi_pdriver's probe.") this
variable is only properly initialized *after* probing and this can
result in a NULL pointer dereference.
In order to fix this without reverting the commit, register the platform
bundle in two steps, first create and initialize tpacpi_pdev, then
register the driver synchronously with platform_driver_probe(). This way
the benefits of commit 38b9ab80db31 are preserved.
Additionally, the commit 43fc63a1e8f6 ("platform/x86: thinkpad_acpi:
Move HWMON initialization to tpacpi_hwmon_pdriver's probe") introduced
a similar problem, however tpacpi_sensors_pdev is only used once inside
the probe, so replace the global reference with the one given by the
probe.
