Currently, when a new fdb entry is added (with both ports of the
ADIN2111 bridged), the driver configures the MAC filters for the wrong
port, which results in the forwarding being done by the host, and not
actually hardware offloaded.
The ADIN2111 offloads the forwarding by setting filters on the
destination MAC address of incoming frames. Based on these, they may be
routed to the other port. Thus, if a frame has to be forwarded from port
1 to port 2, the required configuration for the ADDR_FILT_UPRn register
should set the APPLY2PORT1 bit (instead of APPLY2PORT2, as it's
currently the case).

Setting ethtool -C eth0 tx-usecs 0 is supposed to disable the use of the
coalescing timer but currently it gets programmed with zero delay
instead.
Disable the use of the coalescing timer if tx-usecs is zero by
preventing it from being restarted. Note that to keep things simple we
don't start/stop the timer when the coalescing settings are changed, but
just let that happen on the next transmit or timer expiry.

Kyril reports that crashkernels fail to work on confidential VMs that
rely on the unaccepted memory table, and this appears to be caused by
the fact that it is not considered part of the set of firmware tables
that the crashkernel needs to map.
This is an oversight, and a result of the use of the EFI_LOADER_DATA
memory type for this table. The correct memory type to use for any
firmware table is EFI_ACPI_RECLAIM_MEMORY (including ones created by the
EFI stub), even though the name suggests that is it specific to ACPI.
ACPI reclaim means that the memory is used by the firmware to expose
information to the operating system, but that the memory region has no
special significance to the firmware itself, and the OS is free to
reclaim the memory and use it as ordinary memory if it is not interested
in the contents, or if it has already consumed them. In Linux, this
memory is never reclaimed, but it is always covered by the kernel direct
map and generally made accessible as ordinary memory.
On x86, ACPI reclaim memory is translated into E820_ACPI, which the
kexec logic already recognizes as memory that the crashkernel may need
to to access, and so it will be mapped and accessible to the booting
crash kernel.

snprintf() returns the "number of characters which *would* be generated for
the given input", not the size *really* generated.
In order to avoid too large values for 'o' (and potential negative values
for "sizeof(linebuf) o") use scnprintf() instead of snprintf().
Note that given the "w < 4" in the for loop, the buffer can NOT
overflow, but using the *right* function is always better.

In AHCI 1.3.1, the register description for CAP.SSC:
"When cleared to ‘0’, software must not allow the HBA to initiate
transitions to the Slumber state via agressive link power management nor
the PxCMD.ICC field in each port, and the PxSCTL.IPM field in each port
must be programmed to disallow device initiated Slumber requests."
In AHCI 1.3.1, the register description for CAP.PSC:
"When cleared to ‘0’, software must not allow the HBA to initiate
transitions to the Partial state via agressive link power management nor
the PxCMD.ICC field in each port, and the PxSCTL.IPM field in each port
must be programmed to disallow device initiated Partial requests."
Ensure that we always set the corresponding bits in PxSCTL.IPM, such that
a device is not allowed to initiate transitions to power states which are
unsupported by the HBA.
DevSleep is always initiated by the HBA, however, for completeness, set the
corresponding bit in PxSCTL.IPM such that agressive link power management
cannot transition to DevSleep if DevSleep is not supported.
sata_link_scr_lpm() is used by libahci, ata_piix and libata-pmp.
However, only libahci has the ability to read the CAP/CAP2 register to see
if these features are supported. Therefore, in order to not introduce any
regressions on ata_piix or libata-pmp, create flags that indicate that the
respective feature is NOT supported. This way, the behavior for ata_piix
and libata-pmp should remain unchanged.
This change is based on a patch originally submitted by Runa Guo-oc.

Pull drm ci scripts from Dave Airlie:
"This is a bunch of ci integration for the freedesktop gitlab instance
where we currently do upstream userspace testing on diverse sets of
GPU hardware. From my perspective I think it's an experiment worth
going with and seeing how the benefits/noise playout keeping these
files useful.
Ideally I'd like to get this so we can do pre-merge testing on PRs
eventually.
Below is some info from danvet on why we've ended up making the
decision and how we can roll it back if we decide it was a bad plan.
Why in upstream?
- like documentation, testcases, tools CI integration is one of these
things where you can waste endless amounts of time if you
accidentally have a version that doesn't match your source code
- but also like the above, there's a balance, this is the initial cut
of what we think makes sense to keep in sync vs out-of-tree,
probably needs adjustment
- gitlab supports out-of-repo gitlab integration and that's what's
been used for the kernel in drm, but it results in per-driver
fragmentation and lots of duplicated effort. the simple act of
smashing an arbitrary winner into a topic branch already started
surfacing patches on dri-devel and sparking good cross driver team
discussions
Why gitlab?
- it's not any more shit than any of the other CI
- drm userspace uses it extensively for everything in userspace, we
have a lot of people and experience with this, including
integration of hw testing labs
- media userspace like gstreamer is also on gitlab.fd.o, and there's
discussion to extend this to the media subsystem in some fashion
Can this be shared?
- there's definitely a pile of code that could move to scripts/ if
other subsystem adopt ci integration in upstream kernel git. other
bits are more drm/gpu specific like the igt-gpu-tests/tools
integration
- docker images can be run locally or in other CI runners
Will we regret this?
- it's all in one directory, intentionally, for easy deletion
- probably 1-2 years in upstream to see whether this is worth it or a
Big Mistake. that's roughly what it took to _really_ roll out solid
CI in the bigger userspace projects we have on gitlab.fd.o like
mesa3d"

The access to page pool `cache' array and the `count' variable
is not locked. Page pool cache access is fine as long as there
is only one consumer per pool.
octeontx2 driver fills in rx buffers from page pool in NAPI context.
If system is stressed and could not allocate buffers, refiiling work
will be delegated to a delayed workqueue. This means that there are
two cosumers to the page pool cache.
Either workqueue or IRQ/NAPI can be run on other CPU. This will lead
to lock less access, hence corruption of cache pool indexes.
To fix this issue, NAPI is rescheduled from workqueue context to refill
rx buffers.

"Here is one last fixup for your tree for 6.6-rc1. It resolves a
problem with the way that symbol_get was changed in the module tree

As the changelog comment says:
In commit 9011e49d54dc ("modules: only allow symbol_get of
EXPORT_SYMBOL_GPL modules") the use of symbol_get is properly
restricted to GPL-only marked symbols. This interacts oddly with the
DVB logic which only uses dvb_attach() to load the dvb driver which

Fix this up by properly marking all of the dvb_attach attach symbols

This has been acked by Hans from the V4L driver side, Luis from the
module side, Mauro on the media side, and Christoph said it was the
correct solution, and was tested by the original reporter of the

This reverts commit d5af729dc2071273f14cbb94abbc60608142fd83.
d5af729dc207 ("PCI: Mark NVIDIA T4 GPUs to avoid bus reset") avoided
Secondary Bus Reset on the T4 because the reset seemed to not work when the
T4 was directly attached to a Root Port.
But NVIDIA thinks the issue is probably related to some issue with the Root
Port, not with the T4. The T4 provides neither PM nor FLR reset, so
masking bus reset compromises this device for assignment scenarios.
Revert d5af729dc207 as requested by Wu Zongyong. This will leave SBR
broken in the specific configuration Wu tested, as it was in v6.5, so Wu
will debug that further.

Alexandre Ghiti <[email protected]> says:
The following KASLR implementation allows to randomize the kernel mapping:
- virtually: we expect the bootloader to provide a seed in the device-tree
- physically: only implemented in the EFI stub, it relies on the firmware to
provide a seed using EFI_RNG_PROTOCOL. arm64 has a similar implementation
hence the patch 3 factorizes KASLR related functions for riscv to take
advantage.
The new virtual kernel location is limited by the early page table that only
has one PUD and with the PMD alignment constraint, the kernel can only take
< 512 positions.

non-coherent DMA support for AX45MP
====================================
On the Andes AX45MP core, cache coherency is a specification option so it
may not be supported. In this case DMA will fail. To get around with this
issue this patch series does the below:
1] Andes alternative ports is implemented as errata which checks if the
IOCP is missing and only then applies to CMO errata. One vendor specific
SBI EXT (ANDES_SBI_EXT_IOCP_SW_WORKAROUND) is implemented as part of
errata.
Below are the configs which Andes port provides (and are selected by
RZ/Five):
- ERRATA_ANDES
- ERRATA_ANDES_CMO
OpenSBI patch supporting ANDES_SBI_EXT_IOCP_SW_WORKAROUND SBI is now
part v1.3 release.
2] Andes AX45MP core has a Programmable Physical Memory Attributes (PMA)
block that allows dynamic adjustment of memory attributes in the runtime.
It contains a configurable amount of PMA entries implemented as CSR
registers to control the attributes of memory locations in interest.
OpenSBI configures the PMA regions as required and creates a reserve memory
node and propagates it to the higher boot stack.
Currently OpenSBI (upstream) configures the required PMA region and passes
this a shared DMA pool to Linux.
reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;
pma_resv0@58000000 {
compatible = "shared-dma-pool";
reg = <0x0 0x58000000 0x0 0x08000000>;
no-map;
linux,dma-default;
};
};
The above shared DMA pool gets appended to Linux DTB so the DMA memory
requests go through this region.
3] We provide callbacks to synchronize specific content between memory and
cache.
4] RZ/Five SoC selects the below configs
- AX45MP_L2_CACHE
- DMA_GLOBAL_POOL
- ERRATA_ANDES
- ERRATA_ANDES_CMO

- Add a framework to allow "caching" feature flags so that KVM can
check if the guest can use a feature without needing to search

- Rip out the ancient MMU_DEBUG crud and replace the useful bits with
CONFIG_KVM_PROVE_MMU
- Fix KVM's handling of !visible guest roots to avoid premature
triple fault injection
- Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the

enetc_psi_create() returns an ERR_PTR() or a valid station interface
pointer, but checking for the non-NULL quality of the return code blurs
that difference away. So if enetc_psi_create() fails, we call
enetc_psi_destroy() when we shouldn't. This will likely result in
crashes, since enetc_psi_create() cleans up everything after itself when
it returns an ERR_PTR().

Pull more s390 updates from Heiko Carstens:
- A couple of virtual vs physical address confusion fixes
- Rework locking in dcssblk driver to address a lockdep warning
- Remove support for "noexec" kernel command line option since there is
no use case where it would make sense
- Simplify kernel mapping setup and get rid of quite a bit of code
- Add architecture specific __set_memory_yy() functions which allow us
to modify kernel mappings. Unlike the set_memory_xx() variants they
take void pointer start and end parameters, which allows using them
without the usual casts, and also to use them on areas larger than
8TB.
Note that the set_memory_xx() family comes with an int num_pages
parameter which overflows with 8TB. This could be addressed by
changing the num_pages parameter to unsigned long, however requires
to change all architectures, since the module code expects an int
parameter (see module_set_memory()).
This was indeed an issue since for debug_pagealloc() we call
set_memory_4k() on the whole identity mapping. Therefore address this
for now with the __set_memory_yy() variant, and address common code
later
- Use dev_set_name() and also fix memory leak in zcrypt driver error

Commit 254986e324ad ("drm/radeon: Use the drm suballocation manager implementation.")
made the fence wait in amdgpu_sa_bo_new() interruptible but there is no
code to handle an interrupt. This caused the kernel to randomly explode
in high-VRAM-pressure situations so make it uninterruptible again.

HNS3 NIC does not support GSO partial packets segmentation. Actually tunnel
packets for example NvGRE packets segment offload and checksum offload is
already supported. There is no need to keep gso partial feature bit. So
this patch removes it.

We hope that tc qdisc and dcb ets commands can not be used crosswise.
If we want to use any of the commands to configure tc,
We must use the other command to clear the existing configuration.
However, when we configure a single tc with tc qdisc,
we can still configure it with dcb ets.
Because we use mqprio_active as the tag of tc qdisc configuration,
but with dcb ets, we do not check mqprio_active.
This patch fix this issue by check mqprio_active before
executing the dcb ets command. and add dcb_ets_active to
replace HCLGE_FLAG_DCB_ENABLE and HCLGE_FLAG_MQPRIO_ENABLE
at the hclge layer,

Now in hns3_dbg_uninit(), there may be concurrency between
kfree buffer and read, it may result in memory error.
Moving debugfs_remove_recursive() in front of kfree buffer to ensure
they don't happen at the same time.

req1->tcam_data is defined as "u8 tcam_data[8]", and we convert it as
(u32 *) without considerring byte order conversion,
it may result in printing wrong data for tcam_data.
Convert tcam_data to (__le32 *) first to fix it.
