8eeb10e7a0 pinctrl: rockchip: fix pinmux reset in rockchip_pmx_set
[ Upstream commit 4ea4d4808e342ddf89ba24b93ffa2057005aaced ]

rockchip_pmx_set reset all pinmuxs in group to 0 in the case of error,
add missing bank data retrieval in that code to avoid setting mux on
unexpected pins.

4e4b77f5b5 pinctrl: rockchip: use dedicated pinctrl type for RK3328
[ Upstream commit 01b4b1d1cec48ef4c26616c2fc4600b2c9fec05a ]

rk3328_pin_ctrl uses type of RK3288 which has a hack in
rockchip_pinctrl_suspend and rockchip_pinctrl_resume to restore GPIO6-C6
at assume, the hack is not applicable to RK3328 as GPIO6 is not even
exist in it. So use a dedicated pinctrl type to skip this hack.

78705ebad7 pinctrl: rockchip: fix pinmux bits for RK3328 GPIO2-B pins
[ Upstream commit e8448a6c817c2aa6c6af785b1d45678bd5977e8d ]

The pinmux bits for GPIO2-B0 to GPIO2-B6 actually have 2 bits width,

recalculated so it remain unchanged.

The pinmux bits for those pins are not explicitly specified in RK3328

e737b09b1b pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER
[ Upstream commit adec57ff8e66aee632f3dd1f93787c13d112b7a1 ]

In create_pinctrl(), pinctrl_maps_mutex is acquired before calling
add_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl()
calls pinctrl_free(). However, pinctrl_free() attempts to acquire
pinctrl_maps_mutex, which is already held by create_pinctrl(), leading to
a potential deadlock.

This patch resolves the issue by releasing pinctrl_maps_mutex before
calling pinctrl_free(), preventing the deadlock.

This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

32873ebd2a ACPI: x86: Force StorageD3Enable on more products
[ Upstream commit e79a10652bbd320649da705ca1ea0c04351af403 ]

A Rembrandt-based HP thin client is reported to have problems where
the NVME disk isn't present after resume from s2idle.

This is because the NVME disk wasn't put into D3 at suspend, and
that happened because the StorageD3Enable _DSD was missing in the BIOS.

As AMD's architecture requires that the NVME is in D3 for s2idle, adjust
the criteria for force_storage_d3 to match *all* Zen SoCs when the FADT
advertises low power idle support.

This will ensure that any future products with this BIOS deficiency don't
need to be added to the allow list of overrides.

9b478dd1ae ACPI: x86: utils: Add Picasso to the list for forcing StorageD3Enable
[ Upstream commit 10b6b4a8ac6120ec36555fd286eed577f7632e3b ]

Picasso was the first APU that introduced s2idle support from AMD,
and it was predating before vendors started to use `StorageD3Enable`
in their firmware.

Windows doesn't have problems with this hardware and NVME so it was
likely on the list of hardcoded CPUs to use this behavior in Windows.

Add it to the list for Linux to avoid NVME resume issues.

use of _ADR 0 to force StorageD3Enable.

It was reported that several more Dell systems suffered the same symptoms.
As the list is continuing to grow but these are all Cezanne systems,
instead add Cezanne to the CPU list to apply the StorageD3Enable property
and remove the whole list.

It was also reported that an HP system only has StorageD3Enable on the ACPI
device for the first NVME disk, not the second.

[ Upstream commit 018d6711c26e4bd26e20a819fcc7f8ab902608f3 ]

Dell Inspiron 14 2-in-1 has two ACPI nodes under GPP1 both with _ADR of
0, both without _HID.  It's ambiguous which the kernel should take, but
it seems to take "DEV0".  Unfortunately "DEV0" is missing the device
property `StorageD3Enable` which is present on "NVME".

To avoid this causing problems for suspend, add a quirk for this system
to behave like `StorageD3Enable` property was found.

ff9b9e9776 ACPI: Add quirks for AMD Renoir/Lucienne CPUs to force the D3 hint
[ Upstream commit 6485fc18faa01e8845b1e5bb55118e633f84d1f2 ]

AMD systems from Renoir and Lucienne require that the NVME controller
is put into D3 over a Modern Standby / suspend-to-idle
cycle.  This is "typically" accomplished using the `StorageD3Enable`
property in the _DSD, but this property was introduced after many
of these systems launched and most OEM systems don't have it in
their BIOS.

On AMD Renoir without these drives going into D3 over suspend-to-idle
the resume will fail with the NVME controller being reset and a trace
like this in the kernel logs:
```
[   83.556118] nvme nvme0: I/O 161 QID 2 timeout, aborting

```

The Microsoft documentation for StorageD3Enable mentioned that Windows has
a hardcoded allowlist for D3 support, which was used for these platforms.
Introduce quirks to hardcode them for Linux as well.

As this property is now "standardized", OEM systems using AMD Cezanne and
newer APU's have adopted this property, and quirks like this should not be
necessary.

1952222ec6 r8169: Fix possible ring buffer corruption on fragmented Tx packets.
[ Upstream commit c71e3a5cffd5309d7f84444df03d5b72600cc417 ]

An issue was found on the RTL8125b when transmitting small fragmented
packets, whereby invalid entries were inserted into the transmit ring
buffer, subsequently leading to calls to dma_unmap_single() with a null
address.

This was caused by rtl8169_start_xmit() not noticing changes to nr_frags
which may occur when small packets are padded (to work around hardware
quirks) in rtl8169_tso_csum_v2().

To fix this, postpone inspecting nr_frags until after any padding has been
applied.

In addition replace the write to tp->dirty_tx and the following
smp_mb() with an equivalent call to smp_store_mb(). This implicitly
adds a WRITE_ONCE() to the write.

c616241008 bcache: fix variable length array abuse in btree_iter
[ Upstream commit 3a861560ccb35f2a4f0a4b8207fa7c2a35fc7f31 ]

btree_iter is used in two ways: either allocated on the stack with a
fixed size MAX_BSETS, or from a mempool with a dynamic size based on the
specific cache set. Previously, the struct had a fixed-length array of
size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized
iterators, which causes UBSAN to complain.

This patch uses the same approach as in bcachefs's sort_iter and splits
the iterator into a btree_iter with a flexible array member and a
btree_iter_stack which embeds a btree_iter as well as a fixed-length

[ Upstream commit eda4923d78d634482227c0b189d9b7ca18824146 ]

'nr' member of struct spmi_controller, which serves as an identifier
for the controller/bus. This value is a dynamic ID assigned in
spmi_controller_alloc, and overriding it from the driver results in an
ida_free error "ida_free called for id=xx which is not allocated".

[ Upstream commit 670c900f69645db394efb38934b3344d8804171a ]

When the dts file has multiple referrers to a single PD (e.g.
simple-framebuffer and dss nodes both point to the DSS power-domain) the
ti-sci driver will create two power domains, both with the same ID, and
that will cause problems as one of the power domains will hide the other
one.

Fix this checking if a PD with the ID has already been created, and only
create a PD for new IDs.

bdeaf0c34b wifi: rtlwifi: rtl8192de: Fix 5 GHz TX power
[ Upstream commit de4d4be4fa64ed7b4aa1c613061015bd8fa98b24 ]

Different channels have different TX power settings. rtl8192de is using
the TX power setting from the wrong channel in the 5 GHz band because
_rtl92c_phy_get_rightchnlplace expects an array which includes all the
channel numbers, but it's using an array which includes only the 5 GHz
channel numbers.

Use the array channel_all (defined in rtl8192de/phy.c) instead of
the incorrect channel5g (defined in core.c).

Tested only with rtl8192du, which will use the same TX power code.

commit 5a72477273066b5b357801ab2d315ef14949d402 upstream.

Setting IACK bit when core is disabled does not clear the "Interrupt Flag"
bit in the status register, and the interrupt remains pending.

Sometimes it causes failure for the very first message transfer, that is
usually a device probe.

Hence, set IACK bit after core is enabled to clear pending interrupt.

[ Upstream commit a83e1385b780d41307433ddbc86e3c528db031f0 ]

Undo the modifications made in commit d410ee5109a1 ("ACPICA: avoid
"Info: mapping multiple BARs. Your kernel is fine.""). The initial
purpose of this commit was to stop memory mappings for operation
regions from overlapping page boundaries, as it can trigger warnings
if different page attributes are present.

However, it was found that when this situation arises, mapping
continues until the boundary's end, but there is still an attempt to
read/write the entire length of the map, leading to a NULL pointer
deference. For example, if a four-byte mapping request is made but
only one byte is mapped because it hits the current page boundary's
end, a four-byte read/write attempt is still made, resulting in a NULL
pointer deference.

Instead, map the entire length, as the ACPI specification does not
mandate that it must be within the same page boundary. It is
permissible for it to be mapped across different regions.

[ Upstream commit e32622f84ae289dc7a04e9f01cd62cb914fdc5c6 ]

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

4ab8b37ae0 virtio_net: checksum offloading handling fix
[ Upstream commit 604141c036e1b636e2a71cf6e1aa09d1e45f40c2 ]

In virtio spec 0.95, VIRTIO_NET_F_GUEST_CSUM was designed to handle
partially checksummed packets, and the validation of fully checksummed
packets by the device is independent of VIRTIO_NET_F_GUEST_CSUM
negotiation. However, the specification erroneously stated:

  "If VIRTIO_NET_F_GUEST_CSUM is not negotiated, the device MUST set flags
   to zero and SHOULD supply a fully checksummed packet to the driver."

This statement is inaccurate because even without VIRTIO_NET_F_GUEST_CSUM
negotiation, the device can still set the VIRTIO_NET_HDR_F_DATA_VALID flag.
Essentially, the device can facilitate the validation of these packets'
checksums - a process known as RX checksum offloading - removing the need
for the driver to do so.

This scenario is currently not implemented in the driver and requires
correction. The necessary specification correction[1] has been made and
approved in the virtio TC vote.

  ACPI Error: Aborting method \AMD3._ON due to previous error (AE_AML_LOOP_TIMEOUT) (20230628/psparse-529)

  radeon 0000:01:00.0: not ready 65535ms after resume; giving up
  radeon 0000:01:00.0: Unable to change power state from D3cold to D0, device inaccessible

The issue is that the Root Port the dGPU is connected to can't handle the
transition from D3cold to D0 so the dGPU can't properly exit runtime PM.

The existing logic in pci_bridge_d3_possible() checks for systems that are
newer than 2015 to decide that D3 is safe.  This would nominally work for
an Ivy Bridge system (which was discontinued in 2015), but this system
appears to have continued to receive BIOS updates until 2017 and so this
existing logic doesn't appropriately capture it.

Add the system to bridge_d3_blacklist to prevent D3cold from being used.

469fd5412c usb: misc: uss720: check for incompatible versions of the Belkin F5U002
[ Upstream commit 3295f1b866bfbcabd625511968e8a5c541f9ab32 ]

The incompatible device in my possession has a sticker that says
"F5U002 Rev 2" and "P80453-B", and lsusb identifies it as
"050d:0002 Belkin Components IEEE-1284 Controller". There is a bug
report from 2007 from Michael Trausch who was seeing the exact same
errors that I saw in 2024 trying to use this cable.

[ Upstream commit 80fea979dd9d48d67c5b48d2f690c5da3e543ebd ]

If devm_add_action() returns -ENOMEM, then MSIs are allocated but not
not freed on teardown. Use devm_add_action_or_reset() instead to keep
the static analyser happy.

276dc5f9e3 drm/lima: mask irqs in timeout path before hard reset
[ Upstream commit a421cc7a6a001b70415aa4f66024fa6178885a14 ]

There is a race condition in which a rendering job might take just long
enough to trigger the drm sched job timeout handler but also still
complete before the hard reset is done by the timeout handler.
This runs into race conditions not expected by the timeout handler.
In some very specific cases it currently may result in a refcount
imbalance on lima_pm_idle, with a stack dump such as:

[10136.669170] WARNING: CPU: 0 PID: 0 at drivers/gpu/drm/lima/lima_devfreq.c:205 lima_devfreq_record_idle+0xa0/0xb0
...
[10136.669459] pc : lima_devfreq_record_idle+0xa0/0xb0
...
[10136.669628] Call trace:
[10136.669634]  lima_devfreq_record_idle+0xa0/0xb0
[10136.669646]  lima_sched_pipe_task_done+0x5c/0xb0
[10136.669656]  lima_gp_irq_handler+0xa8/0x120
[10136.669666]  __handle_irq_event_percpu+0x48/0x160
[10136.669679]  handle_irq_event+0x4c/0xc0

We can prevent that race condition entirely by masking the irqs at the
beginning of the timeout handler, at which point we give up on waiting
for that job entirely.
The irqs will be enabled again at the next hard reset which is already
done as a recovery by the timeout handler.

cbf63ffdc3 drm/lima: add mask irq callback to gp and pp
[ Upstream commit 49c13b4d2dd4a831225746e758893673f6ae961c ]

This is needed because we want to reset those devices in device-agnostic
code such as lima_sched.
In particular, masking irqs will be useful before a hard reset to
prevent race conditions.

8c9eb69002 drm/amd/display: Exit idle optimizations before HDCP execution
[ Upstream commit f30a3bea92bdab398531129d187629fb1d28f598 ]

[WHY]
PSP can access DCN registers during command submission and we need
to ensure that DCN is not in PG before doing so.

[HOW]
Add a callback to DM to lock and notify DC for idle optimization exit.
It can't be DC directly because of a potential race condition with the
link protection thread and the rest of DM operation.
