* kvm-arm64/pkvm-fixed-features-6.14: (24 commits)
: .
: Complete rework of the pKVM handling of features, catching up
: with the rest of the code deals with it these days.
: Patches courtesy of Fuad Tabba. From the cover letter:
:
: "This patch series uses the vm's feature id registers to track the
: supported features, a framework similar to nested virt to set the
: trap values, and removes the need to store cptr_el2 per vcpu in
: favor of setting its value when traps are activated, as VHE mode
: does."
:
: This branch drags the arm64/for-next/cpufeature branch to solve
: ugly conflicts in -next.

* kvm-arm64/pkvm-np-guest:
: .
: pKVM support for non-protected guests using the standard MM
: infrastructure, courtesy of Quentin Perret. From the cover letter:
:
: "This series moves the stage-2 page-table management of non-protected
: guests to EL2 when pKVM is enabled. This is only intended as an
: incremental step towards a 'feature-complete' pKVM, there is however a
: lot more that needs to come on top.
:
: With that series applied, pKVM provides near-parity with standard KVM
: from a functional perspective all while Linux no longer touches the
: stage-2 page-tables itself at EL1. The majority of mm-related KVM
: features work out of the box, including MMU notifiers, dirty logging,
: RO memslots and things of that nature. There are however two gotchas:
:
: - We don't support mapping devices into guests: this requires
: additional hypervisor support for tracking the 'state' of devices,
: which will come in a later series. No device assignment until then.
:
: - Stage-2 mappings are forced to page-granularity even when backed by a
: huge page for the sake of simplicity of this series. I'm only aiming
: at functional parity-ish (from userspace's PoV) for now, support for
: HP can be added on top later as a perf improvement."

The Branch Record Buffer Extension (BRBE) adds a number of system
registers and instructions which we don't currently intend to expose to
guests. Our existing logic handles this safely, but this could be
improved with some explicit handling of BRBE.
KVM currently hides BRBE from guests: the cpufeature code's
ftr_id_aa64dfr0[] table doesn't have an entry for the BRBE field, and so
this will be zero in the sanitised value of ID_AA64DFR0 exposed to
guests via read_sanitised_id_aa64dfr0_el1().
KVM currently traps BRBE usage from guests: the default configuration of
the fine-grained trap controls HDFGRTR_EL2.{nBRBDATA,nBRBCTL,nBRBIDR}
and HFGITR_EL2.{nBRBINJ_nBRBIALL} cause these to be trapped to EL2.
Well-behaved guests shouldn't try to use the registers or instructions,
but badly-behaved guests could use these, resulting in unnecessary
warnings from KVM before it injects an UNDEF, e.g.
| kvm [197]: Unsupported guest access at: 401c98
| { Op0( 2), Op1( 1), CRn( 9), CRm( 0), Op2( 0), func_read },
| kvm [197]: Unsupported guest access at: 401d04
| { Op0( 2), Op1( 1), CRn( 9), CRm( 0), Op2( 1), func_read },
| kvm [197]: Unsupported guest access at: 401d70

| { Op0( 2), Op1( 1), CRn( 9), CRm( 1), Op2( 0), func_read },
| kvm [197]: Unsupported guest access at: 401e48
| { Op0( 2), Op1( 1), CRn( 9), CRm( 1), Op2( 1), func_read },
| kvm [197]: Unsupported guest access at: 401eb4
| { Op0( 2), Op1( 1), CRn( 9), CRm( 1), Op2( 2), func_read },
| kvm [197]: Unsupported guest access at: 401f20
| { Op0( 2), Op1( 1), CRn( 9), CRm( 0), Op2( 2), func_read },
| kvm [197]: Unsupported guest access at: 401f8c
| { Op0( 1), Op1( 1), CRn( 7), CRm( 2), Op2( 4), func_write },
| kvm [197]: Unsupported guest access at: 401ff8
| { Op0( 1), Op1( 1), CRn( 7), CRm( 2), Op2( 5), func_write },
As with other features that we know how to handle, these warnings aren't
particularly interesting, and we can simply treat these as UNDEFINED
without any warning. Add the necessary fine-grained undef configuration
to make this happen, as suggested by Marc Zyngier:
https://lore.kernel.org/linux-arm-kernel/86r0czk6wd.wl-maz@kernel.org/
At the same time, update read_sanitised_id_aa64dfr0_el1() to hide BRBE
from guests, as we do for SPE. This will prevent accidentally exposing
BRBE to guests if/when ftr_id_aa64dfr0[] gains a BRBE entry.

For interrupt-map entries, the DTS specification requires
that #address-cells is defined for both the child node and the
interrupt parent. For the PCIe interrupt-map entries, the parent
node ("gic") has not specified #address-cells. The existing layout
of the PCIe interrupt-map entries indicates that it assumes
that #address-cells is zero for this node.
Explicitly set #address-cells to zero for "gic" so that it complies
with the device tree specification.
NVIDIA EDK2 works around this issue by assuming #address-cells
is zero in this scenario, but that workaround is being removed and so
this update is needed or else NVIDIA EDK2 cannot successfully parse the
device tree and the board cannot boot.

Switch to using hvhdk.h everywhere in the kernel. This header
includes all the new Hyper-V headers in include/hyperv, which form a
superset of the definitions found in hyperv-tlfs.h.
This makes it easier to add new Hyper-V interfaces without being
restricted to those in the TLFS doc (reflected in hyperv-tlfs.h).
To be more consistent with the original Hyper-V code, the names of
some definitions are changed slightly. Update those where needed.
Update comments in mshyperv.h files to point to include/hyperv for
adding new definitions.

affect the achieved speed, but it prompted this investigation.
Cycling through the rx_delay range on six boards (see table below) of
various ages shows that there is a large good region from 0x12 to 0x35
where we see zero crc errors on all tested boards.
The old rx_delay value (0x10) seems to have always been on the edge for
the KSZ9031RNX that is usually placed on Puma.
Choose "rx_delay = 0x23" to put us smack in the middle of the good
region. This works fine as well with the KSZ9131RNX PHY that was used
for a small number of boards during the COVID chip shortages.

Since the commit 8a469ee35606 ("arm64: dts: rockchip: Add txpbl node for
RK3399/RK3328"), having "snps,txpbl" properties defined as Ethernet stability
fixes in RK3328-based board dts(i) files is redundant, because that commit
added the required fix to the RK3328 SoC dtsi, so let's delete them.
It has been determined that the Ethernet stability fixes no longer require
"snps,rxpbl", "snps,aal" and "snps,force_thresh_dma_mode" properties, [1][2]
out of which the last two also induce performance penalties, so let's delete
these properties from the relevant RK3328-based board dts(i) files.
This commit completes the removal of these redundant "snps,*" DT properties
that was started by a patch from Peter Geis. [3]

Access to safety cluster engine (SCE) fabric registers was blocked
by firewall after the introduction of Functional Safety Island in
Tegra234. After that, any access by software to SCE registers is
correctly resulting in the internal bus error. However, when CPUs
try accessing the SCE-fabric registers to print error info,
another firewall error occurs as the fabric registers are also
firewall protected. This results in a second error to be printed.
Disable the SCE fabric node to avoid printing the misleading error.
The first error info will be printed by the interrupt from the
fabric causing the actual access.

When a kthread or any other task has an affinity mask that is fully
offline or unallowed, the scheduler reaffines the task to all possible
CPUs as a last resort.
This default decision doesn't mix up very well with nohz_full CPUs that
are part of the possible cpumask but don't want to be disturbed by
unbound kthreads or even detached pinned user tasks.
Make the fallback affinity setting aware of nohz_full.

Similar to the TI K3-AM62x SoC commit ce27f7f9e328c8582a169f97f1466976561f1
("arm64: dts: ti: k3-am62-wakeup: Configure ti-sysc for wkup_uart0"),
The devices in the wkup domain are capable of waking up the system from
suspend. We can configure the wkup domain devices in a generic way using
the ti-sysc interconnect target module driver like we have done with the
earlier TI SoCs.
As ti-sysc manages the SYSCONFIG related registers independent of the
child hardware device, the wake-up configuration is also set even if
wkup_uart0 is reserved by sysfw.
The wkup_uart0 device has interconnect target module register mapping like
dra7 wkup uart. There is a 1 MB interconnect target range with one uart IP
block in the target module. The power domain and clock affects the whole
interconnect target module.
Note we change the functional clock name to follow the ti-sysc binding
and use "fck" instead of "fclk".
Also note that we need to disable the target module reset as noted by
Markus. Otherwise the sysfw using wkup_uart0 can get confused on some
devices leading to boot time issues such as mbox timeouts.

The reset deassert time for the DP83TD510E is incorrectly set to
60000us, while the datasheet states that the minimum time required
after an hard reset is 30us (while 60ms is the time required for the
Power-On Reset after supply stabilization). The error probably arose
from the two timings being indicated by the same symbol (T2).
Lower the required time to 35us, aligning it to the value required for
the PHY to complete the reset AND to be able to accept the RMII master
clock. This saves ~60ms on boot if the MDIO driver is built-in.

SolidRun HummingBoard-T has two options for M.2 connector, supporting
either PCI-E or USB-3.1 Gen 1 - depending on configuration of a mux
on the serdes lane.
The required configurations in device-tree were modeled as overlays.
The USB-3.1 overlay uses /delete-property/ to unset a boolean property
on the usb controller limiting it to USB-2.0 by default.
Overlays can not delete a property from the base dtb, therefore this
overlay is at this time useless.
Convert both overlays into full dts by including the base board dts.
While the pcie overlay was functional, both are converted for a
consistent user experience when selecting between the two mutually
exclusive configurations.
