It's possible to build a kernel with tmp108 built-in but i3c support
in a loadable module, but that results in a link failure:
x86_64-linux-ld: drivers/hwmon/tmp108.o: in function `p3t1085_i3c_probe':
tmp108.c:(.text+0x5f9): undefined reference to `i3cdev_to_dev'
Add a Kconfig dependency to ensure only the working configurations
are allowed.

This patch fixes an issue in the function xenbus_dev_probe(). In the
xenbus_dev_probe() function, within the if (err) branch at line 313, the
program incorrectly returns err directly without releasing the resources
allocated by err = drv->probe(dev, id). As the return value is non-zero,
the upper layers assume the processing logic has failed. However, the probe
operation was performed earlier without a corresponding remove operation.
Since the probe actually allocates resources, failing to perform the remove
operation could lead to problems.
To fix this issue, we followed the resource release logic of the
xenbus_dev_remove() function by adding a new block fail_remove before the
fail_put block. After entering the branch if (err) at line 313, the
function will use a goto statement to jump to the fail_remove block,
ensuring that the previously acquired resources are correctly released,
thus preventing the reference count leak.
This bug was identified by an experimental static analysis tool developed
by our team. The tool specializes in analyzing reference count operations
and detecting potential issues where resources are not properly managed.
In this case, the tool flagged the missing release operation as a
potential problem, which led to the development of this patch.

The initial HMAC session feature added TPM bus encryption and/or integrity
protection to various in-kernel TPM operations. This can cause performance
bottlenecks with IMA, as it heavily utilizes PCR extend operations.
In order to mitigate this performance issue, introduce a kernel
command-line parameter to the TPM driver for disabling the integrity
protection for PCR extend operations (i.e. TPM2_PCR_Extend).

blk_mq_flush_plug_list submits requests in the reverse order that they
were submitted, which leads to a rather suboptimal I/O pattern
especially in rotational devices. Fix this by rewriting virtio_queue_rqs
so that it always pops the requests from the passed in request list, and
then adds them to the head of a local submit list. This actually
simplifies the code a bit as it removes the complicated list splicing,
at the cost of extra updates of the rq_next pointer. As that should be
cache hot anyway it should be an easy price to pay.

e1000_down calls netif_queue_set_napi, which assumes that RTNL is held.
There are a few paths for e1000_down to be called in e1000 where RTNL is
not currently being held:
- e1000_shutdown (pci shutdown)
- e1000_suspend (power management)
- e1000_reinit_locked (via e1000_reset_task delayed work)
- e1000_io_error_detected (via pci error handler)
Hold RTNL in three places to fix this issue:
- e1000_reset_task: igc, igb, and e100e all hold rtnl in this path.
- e1000_io_error_detected (pci error handler): e1000e and ixgbe hold
rtnl in this path. A patch has been posted for igc to do the same
[1].
- __e1000_shutdown (which is called from both e1000_shutdown and
e1000_suspend): igb, ixgbe, and e1000e all hold rtnl in the same
path.
The other paths which call e1000_down seemingly hold RTNL and are OK:
- e1000_close (ndo_stop)
- e1000_change_mtu (ndo_change_mtu)
Based on the above analysis and mailing list discussion [2], I believe
adding rtnl in the three places mentioned above is correct.

Since the igc driver doesn't support forced speed configuration and
its current related hardware doesn't support it either, there is no
use of the mac.autoneg parameter. Moreover, in one case this usage
might result in a NULL pointer dereference due to an uninitialized
function pointer, phy.ops.force_speed_duplex.
Therefore, remove this parameter from the igc code.

Header ixgbe_type.h includes ixgbe_mbx.h. Also, header
ixgbe_mbx.h included ixgbe_type.h, thus introducing a circular
dependency.
- Remove ixgbe_mbx.h inclusion from ixgbe_type.h.
- ixgbe_mbx.h requires the definition of struct ixgbe_mbx_operations
so move its definition there. While at it, add missing argument
identifier names.
- Add required forward structure declarations.
- Include ixgbe_mbx.h in the .c files that need it, for the
following reasons:
ixgbe_sriov.c uses ixgbe_check_for_msg
ixgbe_main.c uses ixgbe_init_mbx_params_pf
ixgbe_82599.c uses mbx_ops_generic

therefore be able to run on any CPU. In practice this is already
happening through the unbound ice_service_timer that may fire anywhere
and queue the workqueue accordingly to any CPU.

housekeeping CPUs on nohz_full.

The ice_vc_query_rxdid() function allocates memory to store the
virtchnl_supported_rxdids structure used to communicate the bitmap of
supported RXDIDs to a VF.
This structure is only 8 bytes in size. The function must hold the
allocated length on the stack as well as the pointer to the structure which
itself is 8 bytes. Allocating this storage on the heap adds unnecessary
overhead including a potential error path that must be handled in case
kzalloc fails. Because this structure is so small, we're not saving stack
space. Additionally, because we must ensure that we free the allocated
memory, the return value from ice_vc_send_msg_to_vf() must also be saved in
the stack ret variable. Depending on compiler optimization, this means
allocating the 8-byte structure is requiring up to 16-bytes of stack
memory!
Simplify this function to keep the rxdid variable on the stack, saving
memory and removing a potential failure exit path from this function.

The pf->supported_rxdids field is used to populate the list of valid RXDIDs
that a VF may use when negotiating VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC.
The set of supported RXDIDs is dependent on the DDP, and can be read from
the GLXFLXP_RXDID_FLAGS register. The PF needs to send this list to the
VF upon receiving the VIRTCHNL_OP_GET_SUPPORTED_RXDIDs. It also needs to
use this list to validate the requested descriptor ID from the VF when
programming the Rx queues.
A future update to support VF live migration will also want to validate
that the target VF can support the same descriptor ID when migrating.
Currently, pf->supported_rxdids is initialized inside the
ice_vc_query_rxdid() function. This means that it is only ever initialized
if at least one VF actually tries to negotiate
VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC. It is also unnecessarily re-initialized
every time the VF loads and requests the descriptor list. This worked
before because the PF only checks pf->suppported_rxdids when programming
the Rx queue if the VF actually negotiates the
VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC feature.
This will be problematic for VF live migration. We need the list of
supported Rx descriptor IDs when migrating. It is possible that no VF on
the target PF has ever actually issued a VIRTCHNL_OP_GET_SUPPORTED_RXDIDs.
Refactor the driver to initialize pf->supported_rxdids during driver
initialization after the DDP is loaded. This is simpler, avoids unnecessary
duplicate work, and avoids issues with the live migration process.

Currently when any VF is trusted and true promiscuous mode is enabled on
the PF, the VF will receive all unicast traffic directed to the device's
internal switch. This includes traffic external to the NIC and also from
other VSI (i.e. VFs). This does not match the expected behavior as
unicast traffic should only be visible from external sources in this
case. Disable the Tx promiscuous mode bits for unicast promiscuous mode.

Use netif_napi_add_config to assign persistent per-NAPI config when
initializing NAPIs. This preserves NAPI config settings when queue
counts are adjusted.
Tested with an E810-2CQDA2 NIC.
Begin by setting the queue count to 4:
$ sudo ethtool -L eth4 combined 4
Check the queue settings:
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \
--dump napi-get --json='{"ifindex": 4}'
[{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8452,
'ifindex': 4,
'irq': 2782},
{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8451,
'ifindex': 4,
'irq': 2781},
{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8450,
'ifindex': 4,
'irq': 2780},
{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8449,
'ifindex': 4,
'irq': 2779}]
Now, set the queue with NAPI ID 8451 to have a gro-flush-timeout of
1111:
$ sudo ./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/netdev.yaml \
--do napi-set --json='{"id": 8451, "gro-flush-timeout": 1111}'
None
Check that worked:
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \
--dump napi-get --json='{"ifindex": 4}'
[{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8452,
'ifindex': 4,
'irq': 2782},
{'defer-hard-irqs': 0,
'gro-flush-timeout': 1111,
'id': 8451,
'ifindex': 4,
'irq': 2781},
{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8450,
'ifindex': 4,
'irq': 2780},
{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8449,
'ifindex': 4,
'irq': 2779}]
Now reduce the queue count to 2, which would destroy the queue with NAPI
ID 8451:
$ sudo ethtool -L eth4 combined 2
Check the queue settings, noting that NAPI ID 8451 is gone:
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \
--dump napi-get --json='{"ifindex": 4}'
[{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8450,
'ifindex': 4,
'irq': 2780},
{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8449,
'ifindex': 4,
'irq': 2779}]
Now, increase the number of queues back to 4:
$ sudo ethtool -L eth4 combined 4
Dump the settings, expecting to see the same NAPI IDs as above and for
NAPI ID 8451 to have its gro-flush-timeout set to 1111:
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \
--dump napi-get --json='{"ifindex": 4}'
[{'defer-hard-irqs': 0,
'gro-flush-timeout': 0,
'id': 8452,
'ifindex': 4,
'irq': 2782},
{'defer-hard-irqs': 0,
'gro-flush-timeout': 1111,
'id': 8451,
'ifindex': 4,
'irq': 2781},
{'defer-hard-irqs': 0,

that indicates whether the segment is the last segment that will be
sent to firmware.
If the flag field's valid bit is NOT set, then as was done before,
assume that this is the last segment being downloaded.
However, if the flag field's valid bit IS set, then use the last segment
flag to determine if this segment is the last segment to download.

A few more Qualcomm driver updates for v6.13
Make the Adreno driver invoke the SMMU aperture setup firmware function,
which is required to allow the GPU to manage per-process page tables in
some firmware versions - as an example Rb3Gen2 has no GPU without this.
Add X1E Devkit to the list of devices that has functional EFI variable
access through the uefisecapp.
Flip the "manual slice configuration quirk" in the Qualcomm LLCC driver,
as this only applies to a single platform, and introduce support for

Starting from LNL, CCS has moved over to flat CCS model where there is
now dedicated memory reserved for storing compression state. On
platforms like LNL this reserved memory lives inside graphics stolen
memory, which is not treated like normal RAM and is therefore skipped by
the core kernel when creating the hibernation image. Currently if
something was compressed and we enter hibernation all the corresponding
CCS state is lost on such HW, resulting in corrupted memory. To fix this
evict user buffers from TT -> SYSTEM to ensure we take a snapshot of the
raw CCS state when entering hibernation, where upon resuming we can
restore the raw CCS state back when next validating the buffer. This has
been confirmed to fix display corruption on LNL when coming back from
hibernation.

The GGTT looks to be stored inside stolen memory on igpu which is not
treated as normal RAM. The core kernel skips this memory range when
creating the hibernation image, therefore when coming back from
hibernation the GGTT programming is lost. This seems to cause issues
with broken resume where GuC FW fails to load:
[drm] *ERROR* GT0: load failed: status = 0x400000A0, time = 10ms, freq = 1250MHz (req 1300MHz), done = -1
[drm] *ERROR* GT0: load failed: status: Reset = 0, BootROM = 0x50, UKernel = 0x00, MIA = 0x00, Auth = 0x01
[drm] *ERROR* GT0: firmware signature verification failed
[drm] *ERROR* CRITICAL: Xe has declared device 0000:00:02.0 as wedged.
Current GGTT users are kernel internal and tracked as pinned, so it
should be possible to hook into the existing save/restore logic that we
use for dgpu, where the actual evict is skipped but on restore we
importantly restore the GGTT programming. This has been confirmed to
fix hibernation on at least ADL and MTL, though likely all igpu
platforms are affected.
This also means we have a hole in our testing, where the existing s4
tests only really test the driver hooks, and don't go as far as actually
rebooting and restoring from the hibernation image and in turn powering
down RAM (and therefore losing the contents of stolen).

Implement support for the word delay feature of i.MX51 (and onwards) via
the ECSPI interface.
Convert the requested delay to SPI cycles and account for an extra
inter-word delay inserted by the controller in addition to the requested
number of cycles, which was observed when testing this patch.
Disable dynamic burst when word delay is set. As the configurable delay
period in the controller is inserted after bursts, the burst length must
equal the word length.
Account for word delay in the transfer time estimation for
polling_limit_us.

switching between Frequency and Cache modes. To optimize performance,
implement the AMD 3D V-Cache Optimizer, which allows selecting either:
Frequency mode: cores within the faster CCD are prioritized before
those in the slower CCD.
Cache mode: cores within the larger L3 CCD are prioritized before
those in the smaller L3 CCD.

The current "measurement_chars" CHPID sysfs attribute exposes only a
limited, validity-filtered portion of data from the associated Channel-
Measurements Characteristics Block (CMCB). New machine models add data
that is relevant for userspace tooling to the "header"-portion of the
CMCB. This data that is not currently accessible to userspace.
To prevent having to add new sysfs attributes whenever a new bit of data
is added to the CMCB "header", add a new sysfs attribute named
"measurement_chars_full" that exposes the full, unfiltered CMCB.
