d7d8ab87e3e7 ("PCI: vmd: Switch to msi_create_parent_irq_domain()") added a
WARN_ON sanity check that child devices support MSI-X, because VMD document
says [1]:
Intel VMD only supports MSIx Interrupts from child devices and therefore
the BIOS must enable PCIe Hot Plug and MSIx interrups [sic].
However, the VMD device can't even tell the difference between a child
device using MSI and one using MSI-X. Per 185a383ada2e ("x86/PCI: Add
driver for Intel Volume Management Device (VMD)"), VMD does not support
INTx interrupts, but does support child devices using either MSI or MSI-X.
Remove the sanity check to avoid the WARN_ON and allow child devices to use
MSI, reported by Ammar.

Add a common allocator function for struct intel_digital_port, with some
member default initialization to deduplicate them from everywhere
else. This is similar to intel_connector_alloc().
At least for now, place this in intel_encoder.[ch]. We don't have a
dedicated file for dig port stuff, and there wouldn't be much to add
there anyway. A digital port is a sort of subclass of encoder, so the
location isn't far off the mark.

It turns out that the ECDT table inside the ThinkBook 14 G7 IML
contains a valid EC description but an invalid ID string
("_SB.PC00.LPCB.EC0"). Ignoring this ECDT based on the invalid

so relax the sanity check of the ID string and only reject ECDTs

Clamp writes to power limits powerX_crit/currX_crit, powerX_cap,
powerX_max, to the maximum supported by the pcode mailbox
when sysfs-provided values exceed this limit.
Although the pcode already performs clamping, values beyond the pcode
mailbox's supported range get truncated, leading to incorrect
critical power settings.
This patch ensures proper clamping to prevent such truncation.
v2:
- Address below review comments. (Riana)
- Split comments into multiple sentences.
- Use local variables for readability.
- Add a debug log.
- Use u64 instead of unsigned long.
v3:
- Change drm_dbg logs to drm_info. (Badal)
v4:
- Rephrase the drm_info log. (Rodrigo, Riana)
- Rename variable max_mbx_power_limit to max_supp_power_limit, as

support.

When the xe buffer-object shrinker allows GPU waits and write-back,
(typically from kswapd), perform multiple passes, skipping
subsequent passes if the shrinker number of scanned objects target
is reached.
1) Without GPU waits and write-back
2) Without write-back
3) With both GPU-waits and write-back
This is to avoid stalls and costly write- and readbacks unless they

If the buf + offset is not aligned to XE_CAHELINE_BYTES we fallback to
using a bounce buffer. However the bounce buffer here is allocated on
the stack, and the only alignment requirement here is that it's
naturally aligned to u8, and not XE_CACHELINE_BYTES. If the bounce
buffer is also misaligned we then recurse back into the function again,
however the new bounce buffer might also not be aligned, and might never
be until we eventually blow through the stack, as we keep recursing.
Instead of using the stack use kmalloc, which should respect the
power-of-two alignment request here. Fixes a kernel panic when
triggering this path through eudebug.
v2 (Stuart):
- Add build bug check for power-of-two restriction
- s/EINVAL/ENOMEM/

Commit d33bd88ac0eb ("ACPI: processor: perflib: Fix initial _PPC limit
application") added a pr->performance check that prevents the frequency
QoS request from being added when the given processor has no performance
object. Unfortunately, this causes a WARN() in freq_qos_remove_request()
to trigger on an attempt to take the given CPU offline later because the
frequency QoS object has not been added for it due to the missing
performance object.
Address this by moving the pr->performance check before calling
acpi_processor_get_platform_limit() so it only prevents a limit from
being set for the CPU if the performance object is not present. This
way, the frequency QoS request is added as it was before the above
commit and it is present all the time along with the CPU's cpufreq
policy regardless of whether or not the CPU is online.

LMEM is partitioned between multiple VFs and we expect that the more
VFs we have, the less LMEM is assigned to each VF.
This means that we can achieve full LMEM BAR access without the need to
attempt full VF LMEM BAR resize via pci_resize_resource().
Always try to set the largest possible BAR size that allows to fit the
number of enabled VFs and inform the user in case the resize attempt is
not successful.

A malicious HID device can trigger a slab out-of-bounds during
mt_report_fixup() by passing in report descriptor smaller than
607 bytes. mt_report_fixup() attempts to patch byte offset 607
of the descriptor with 0x25 by first checking if byte offset
607 is 0x15 however it lacks bounds checks to verify if the
descriptor is big enough before conducting this check. Fix
this bug by ensuring the descriptor size is at least 608
bytes before accessing it.

set/get_report operations, which were traced to the
hid_ishtp_cl_resume_handler() timing out while waiting for the ISHTP
resume acknowledgment. The previous timeout was set to 50ms, which proved
insufficient on affected machines.
Empirical measurements on failing systems showed that the time from ISH
resume initiation to receiving the ISHTP resume ack could be as long as
180ms. As a result, the 50ms timeout caused failures.
To address this, increase the wait timeout for ISHTP resume ack from 50ms
to 300ms, providing a safer margin for slower hardware. Additionally, add
error logging when a timeout occurs to aid future debugging and issue
triage. No functional changes are made beyond the timeout adjustment and
improved error reporting.

steelseries_srws1_probe() still does not use devm_kzalloc() and
devm_led_classdev_register(), so there is a lot of code to safely manage
heap, which reduces readability and may cause memory leaks due to minor
patch mistakes in the future.
Therefore, it should be changed to use devm_kzalloc() and
devm_led_classdev_register() to easily and safely manage heap.
Also, the current steelseries driver mainly checks sd->quriks to determine
which product a specific HID device is, which is not the correct way.
remove(), unlike probe(), does not receive struct hid_device_id as an
argument, so it must check hdev unconditionally to know which product
it is.
However, since struct steelseries_device and struct steelseries_srws1_data
have different structures, if SRWS1 is removed in remove(), converts
hdev->dev, which is initialized to struct steelseries_srws1_data,
to struct steelseries_device and uses it. This causes various
memory-related bugs as completely unexpected values exist in member
variables of the structure.
Therefore, in order to modify probe() and remove() to work properly,
Arctis 1, 9 should be added to HID_USB_DEVICE and some functions should be
modified to check hdev->product when determining HID device product.

Chris reported that even on a BIOS that has a new enough SMU F/W
version there is still a spurious IRQ1. Although the solution was
added to SMU F/W 64.66.0 it turns out there needs to be a matching
SBIOS change to activate it. Thus Linux shouldn't be avoiding the
IRQ1 workaround on newer SMU F/W because there is no indication the
BIOS change is in place.
Drop the match for 64.66.0+ and instead match all RN/CZN/BRC (they
all share same SMU F/W). Adjust the quirk infrastructure to allow
quirking the workaround on or off and also adjust existing quirks
to match properly.
Unfortunately this may cause some systems that did have the SBIOS
change in place to regress in keyboard wakeup but we don't have a
way to know. If a user reports a keyboard wakeup regression they can
run with amd_pmc.disable_workarounds=1 to deactivate the workaround
and share DMI data so that their system can be quirked not to use
the workaround in the upstream kernel.

The Dell SMBIOS driver uses the "id" field inside struct device for
prioritizing the WMI backend over the SMM backend. Because of this
the WMI backend modifies the "id" field of the underlying WMI device.
However the WMI core itself uses wdev->dev.id internally to track
device IDs, so modifying this value will result in a resource leak.
Fix this by not using the "id" field inside struct device for SMBIOS
prioritization. Instead extend struct smbios_device with a separate
"priority" field.
Tested on a Dell Inspiron 3505.

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.

In several code paths, such as xe_pt_create(), the vm->xef field is used
to determine whether a VM originates from userspace or the kernel.
Previously, this handler was only assigned in xe_vm_create_ioctl(),
after the VM was created by xe_vm_create(). However, xe_vm_create()
triggers page table creation, and that function assumes vm->xef should
be already set. This could lead to incorrect origin detection.
To fix this problem and ensure consistency in the initialization of
the VM object, let's move the assignment of this handler to
xe_vm_create.
v2:
- take reference to the xe file object only when xef is not NULL
- release the reference to the xe file object on the error path (Matthew)

It's necessary to adjust the MAC TX clock when the linkspeed changes,
but it's noted such adjustment always fails on TH1520 SoC, and reading
back from APB glue registers that control clock generation results in
garbage, causing broken link.
With some testing, it's found a clock must be ungated for access to APB
glue registers. Without any consumer, the clock is automatically
disabled during late kernel startup. Let's get and enable it if it's
described in devicetree.
For backward compatibility with older devicetrees, probing won't fail if
the APB clock isn't found. In this case, we emit a warning since the
link will break if the speed changes.

reset_gpio is claimed in mdiobus_register_device(), but it is not
released in mdiobus_unregister_device(). It is instead only
released when the whole MDIO bus is unregistered.
When a device uses the reset_gpio property, it becomes impossible
to unregister it and register it again, because the GPIO remains
claimed.
This patch resolves that issue.
