Unconditionally clear the TCS_AMC_MODE_TRIGGER bit when a
transaction completes. Previously this bit was only cleared when
a wake TCS was borrowed as an AMC TCS but not for dedicated
AMC TCS. Leaving this bit set for AMC TCS and entering deeper low
power modes can generate a false completion IRQ.
Prevent this scenario by always clearing the TCS_AMC_MODE_TRIGGER
bit upon receiving a completion IRQ.

The qcom_pcie_parse_ports() function currently iterates over all available
child nodes of the PCIe controller's device tree node. This includes
unrelated nodes such as OPP (Operating Performance Points) nodes, which do
not contain the expected 'reset' and 'phy' properties. As a result, parsing
fails and the driver falls back to the legacy method of parsing the
controller node directly. However, this fallback also fails when properties
are shifted to the Root Port node, leading to probe failure.
Fix this by restricting the parsing logic to only consider child nodes with
device_type = "pci", which is the expected and required property for PCIe
bridge nodes as per the pci-bus-common.yaml dtschema.

Replace calls of devm_kzalloc() with devm_kcalloc() in ks_pcie_probe().
As noted in the kernel documentation [1], open-coded multiplication in
allocator arguments is discouraged because it can lead to integer
overflow.
Using devm_kcalloc() provides built-in overflow protection, making the
memory allocation safer when calculating the allocation size compared
to explicit multiplication.

This patch ensures the gt will be awake for the entire duration
of the resume sequences until GuCRC takes over and GT-C6 gets
re-enabled.
Before suspending GT-C6 is kept enabled, but upon resume, GuCRC
is not yet alive to properly control the exits and some cases of
instability and corruption related to GT-C6 can be observed.

the behavior from before commit 061963cd9e5b ("drm/sysfb: Blit to

When being disabled, the plane has no associated CRTC. Trying to deref

Starting with commit f99508074e78 ("PM: domains: Detach on
device_unbind_cleanup()"), there is no longer a need to call
dev_pm_domain_detach() in the bus remove function. The
device_unbind_cleanup() function now handles this to avoid
invoking devres cleanup handlers while the PM domain is
powered off, which could otherwise lead to failures as
described in the above-mentioned commit.
Drop the explicit dev_pm_domain_detach() call and rely instead
on the flags passed to dev_pm_domain_attach() to power off the
domain.

Starting with commit dd26c1a23fd5 ("PCI: rcar-host: Switch to

the object of type struct irq_domain_info passed to:
msi_create_parent_irq_domain() ->
irq_domain_instantiate()() ->
__irq_domain_instantiate()
has no reference to the parent IRQ domain. Using msi->domain->parent as an
argument for generic_handle_domain_irq() leads to below error:
"Unable to handle kernel NULL pointer dereference at virtual address"
This error was identified while switching the upcoming RZ/G3S PCIe host
controller driver to msi_create_parent_irq_domain() (which was using a
similar pattern to handle MSIs (see link section)), but it was not tested
on hardware using the pcie-rcar-host controller driver due to lack of
hardware.

Temporary rename of virtchnl.c into rss.c
In order to split virtchnl.c in a way that makes it much easier
to still blame new file, we do it via multiple git steps.

Move queue configuration functions out of virtchnl.c to queues.c.
Technically the move was started by an earlier commit of the series,
that was duplicating virtchnl.c as queues.c (what forces git to nicely
show blame when asked), followed by a couple of cleanup commits (that
removed stuff that is not moved from the new file, again - multiple
commits, to avoid git saving on changes lines by reusing removed lines
as a content of some kept function), with this final commit actually
enabling compilation of the new file, removing stuff from the virtchnl.c,
and making some moved functions visible (via static keyword removal).

PSR work is using __psr_wait_for_idle_locked to ensure PSR exit is
completed before continuing to PSR activation. __psr_wait_for_idle_locked
is unlocking PSR mutex which allows PSR disable/enable and PSR
pause/resume while PSR idle is being wait. PSR enable status is already
checked after locking again PSR mutex but PSR pause counter check is
missing. Due to this PSR work may continue to PSR activation even PSR is
paused.
Fix this by checking PSR pause counter in __psr_wait_for_idle_locked after
PSR mutex is locked again.

To enable more complex parameterized testing scenarios, the
generate_params() function needs additional context beyond just
the previously generated parameter. This patch modifies the
generate_params() function signature to include an extra
`struct kunit *test` argument, giving test users access to the
parameterized test context when generating parameters.
The `struct kunit *test` argument was added as the first parameter
to the function signature as it aligns with the convention of other
KUnit functions that accept `struct kunit *test` first. This also
mirrors the "this" or "self" reference found in object-oriented
programming languages.
This patch also modifies xe_pci_live_device_gen_param() in xe_pci.c
and nthreads_gen_params() in kcsan_test.c to reflect this signature
change.

The hv_netvsc driver currently enables NAPI after opening the primary and
subchannels. This ordering creates a race: if the Hyper-V host places data
in the host -> guest ring buffer and signals the channel before
napi_enable() has been called, the channel callback will run but
napi_schedule_prep() will return false. As a result, the NAPI poller never
gets scheduled, the data in the ring buffer is not consumed, and the
receive queue may remain permanently stuck until another interrupt happens
to arrive.
Fix this by enabling NAPI and registering it with the RX/TX queues before
vmbus channel is opened. This guarantees that any early host signal after
open will correctly trigger NAPI scheduling and the ring buffer will be
drained.

Currently, in the AF_XDP transmit paths, the CIC bit of
TX Desc3 is set for all packets. Setting this bit for
packets transmitting through queues that don't support
checksum offloading causes the TX DMA to get stuck after
transmitting some packets. This patch ensures the CIC bit
of TX Desc3 is set only if the TX queue supports checksum
offloading.

Correct supported speed modes as per the XGMAC databook.
Commit 9cb54af214a7 ("net: stmmac: Fix IP-cores specific
MAC capabilities") removes support for 10M, 100M and
1000HD. 1000HD is not supported by XGMAC IP, but it does
support 10M and 100M FD mode for XGMAC version >= 2_20,
and it also supports 10M and 100M HD mode if the HDSEL bit
is set in the MAC_HW_FEATURE0 reg. This commit enables support
for 10M and 100M speed modes for XGMAC IP based on XGMAC
version and MAC capabilities.
