perf/x86/uncore: Factor out uncore_device_to_die()

BugLink: https://bugs.launchpad.net/bugs/2030881

The same code is used to retrieve the logical die ID with a given PCI
device in both the discovery code and the code that supports a system
with > 8 nodes.

Factor out uncore_device_to_die() to replace the duplicate code.

No functional change.

nvme-multipath: support io stats on the mpath device

BugLink: https://bugs.launchpad.net/bugs/2023185

Our mpath stack device is just a shim that selects a bottom namespace
and submits the bio to it without any fancy splitting. This also means
that we don't clone the bio or have any context to the bio beyond
submission. However it really sucks that we don't see the mpath device
io stats.

Given that the mpath device can't do that without adding some context
to it, we let the bottom device do it on its behalf (somewhat similar
to the approach taken in nvme_trace_bio_complete).

When the IO starts, we account the request for multipath IO stats using
REQ_NVME_MPATH_IO_STATS nvme_request flag to avoid queue io stats disable
in the middle of the request.

cpufreq: intel_pstate: Fix scaling for hybrid-capable systems with disabled E-cores

https://bugs.launchpad.net/bugs/2030924

Some system BIOS configuration may provide option to disable E-cores.
As part of this change, CPUID feature for hybrid (Leaf 7 sub leaf 0,
EDX[15] = 0) may not be set. But HWP performance limits will still be
using a scaling factor like any other hybrid enabled system.

The current check for applying scaling factor will fail when hybrid
CPUID feature is not set and the only way to make sure that scaling
should be applied by checking CPPC nominal frequency and nominal
performance.

First, or systems predating Alder Lake, the CPPC nominal frequency and
nominal performance are 0, which can be used to distinguish those
systems from hybrid systems with disabled E-cores.

Second, if the CPPC nominal frequency and nominal performance are
defined, which indicates the need to use a special scaling factor, and
the nominal performance value multiplied by 100 is not equal to the
nominal frequency one, use hybrid scaling factor.

This can be done for all HWP systems without additional CPU model check.

This reverts commit 1c5e670d6a5a8e7e99b51f45e79879f7828bd2ec.

LTS 5.15 pulled in several lpfc "SLI Path split" patches. The Path
Split mods were a 14-patch set, which refactors the driver from
to split the sli-3 hw (now eol) from the sli-4 hw and use sli4
structures natively. The patches are highly inter-related.

Given only some of the patches were included, it created a situation
where FLOGI's fail, thus SLI Ports can't start communication.

Reverting this patch as its one of the partial Path Split patches
that was included.

cpufreq: ACPI: Defer setting boost MSRs

When acpi-cpufreq is loaded, boost is enabled on every CPU (by setting an
MSR) before the driver is registered with cpufreq. This can be very time
consuming, because it is done with a CPU hotplug startup callback, and
cpuhp_setup_state() schedules the callback (cpufreq_boost_online()) to run
on each CPU one at a time, waiting for each to run before calling the next.

If cpufreq_register_driver() fails--if, for example, there are no ACPI
P-states present--this is wasted time.

Since cpufreq already sets up a CPU hotplug startup callback if and when
acpi-cpufreq is registered, set the boost MSRs in acpi_cpufreq_cpu_init(),
which is called by the cpufreq cpuhp callback. This allows acpi-cpufreq to
exit quickly if it is loaded but not needed.

On one system with 192 CPUs, this patch speeds up boot by about 30 seconds.

ice: Remove toggling of antispoof for VF trusted promiscuous mode

Currently when a trusted VF enables promiscuous mode spoofchk will be
disabled. This is wrong and should only be modified from the
ndo_set_vf_spoofchk callback. Fix this by removing the call to toggle
spoofchk for trusted VFs.

nvme: expose cntrltype and dctype through sysfs

TP8010 introduces the Discovery Controller Type attribute (dctype).
The dctype is returned in the response to the Identify command. This
patch exposes the dctype through the sysfs. Since the dctype depends on
the Controller Type (cntrltype), another attribute of the Identify
response, the patch also exposes the cntrltype as well. The dctype will
only be displayed for discovery controllers.

A note about the naming of this attribute:
Although TP8010 calls this attribute the Discovery Controller Type,
note that the dctype is now part of the response to the Identify
command for all controller types. I/O, Discovery, and Admin controllers
all share the same Identify response PDU structure. Non-discovery
controllers as well as pre-TP8010 discovery controllers will continue
to set this field to 0 (which has always been the default for reserved
bytes). Per TP8010, the value 0 now means "Discovery controller type is
not reported" instead of "Reserved". One could argue that this
definition is correct even for non-discovery controllers, and by
extension, exposing it in the sysfs for non-discovery controllers is
appropriate.

PCI: pciehp: Ignore Link Down/Up caused by error-induced Hot Reset

Stuart Hayes reports that an error handled by DPC at a Root Port results
in pciehp gratuitously bringing down a subordinate hotplug port:

  RP -- UP -- DP -- UP -- DP (hotplug) -- EP

pciehp brings the slot down because the Link to the Endpoint goes down.
That is caused by a Hot Reset being propagated as a result of DPC.
Per PCIe Base Spec 5.0, section 6.6.1 "Conventional Reset":

  For a Switch, the following must cause a hot reset to be sent on all
  Downstream Ports: [...]

  * The Data Link Layer of the Upstream Port reporting DL_Down status.
    In Switches that support Link speeds greater than 5.0 GT/s, the
    Upstream Port must direct the LTSSM of each Downstream Port to the
    Hot Reset state, but not hold the LTSSMs in that state. This permits
    each Downstream Port to begin Link training immediately after its
    hot reset completes. This behavior is recommended for all Switches.

  * Receiving a hot reset on the Upstream Port.

Once DPC recovers, pcie_do_recovery() walks down the hierarchy and
invokes pcie_portdrv_slot_reset() to restore each port's config space.
At that point, a hotplug interrupt is signaled per PCIe Base Spec r5.0,
section 6.7.3.4 "Software Notification of Hot-Plug Events":

  If the Port is enabled for edge-triggered interrupt signaling using
  MSI or MSI-X, an interrupt message must be sent every time the logical
  AND of the following conditions transitions from FALSE to TRUE: [...]

  * The Hot-Plug Interrupt Enable bit in the Slot Control register is
    set to 1b.

  * At least one hot-plug event status bit in the Slot Status register
    and its associated enable bit in the Slot Control register are both
    set to 1b.

Prevent pciehp from gratuitously bringing down the slot by clearing the
error-induced Data Link Layer State Changed event before restoring
config space. Afterwards, check whether the link has unexpectedly
failed to retrain and synthesize a DLLSC event if so.

Allow each pcie_port_service_driver (one of them being pciehp) to define
a slot_reset callback and re-use the existing pm_iter() function to
iterate over the callbacks.

Thereby, the Endpoint driver remains bound throughout error recovery and
may restore the device to working state.

Surprise removal during error recovery is detected through a Presence
Detect Changed event. The hotplug port is expected to not signal that
event as a result of a Hot Reset.

The issue isn't DPC-specific, it also occurs when an error is handled by
AER through aer_root_reset(). So while the issue was noticed only now,
it's been around since 2006 when AER support was first introduced.
