ARM:
* Nested virtualization support for VGICv3, giving the nested
hypervisor control of the VGIC hardware when running an L2 VM
* Removal of 'late' nested virtualization feature register masking,
making the supported feature set directly visible to userspace
* Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage
of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers
* Paravirtual interface for discovering the set of CPU implementations
where a VM may run, addressing a longstanding issue of guest CPU
errata awareness in big-little systems and cross-implementation VM
migration
* Userspace control of the registers responsible for identifying a
particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1),
allowing VMs to be migrated cross-implementation
* pKVM updates, including support for tracking stage-2 page table
allocations in the protected hypervisor in the 'SecPageTable' stat
* Fixes to vPMU, ensuring that userspace updates to the vPMU after
KVM_RUN are reflected into the backing perf events
LoongArch:
* Remove unnecessary header include path
* Assume constant PGD during VM context switch
* Add perf events support for guest VM
RISC-V:
* Disable the kernel perf counter during configure
* KVM selftests improvements for PMU
* Fix warning at the time of KVM module removal
x86:
* Add support for aging of SPTEs without holding mmu_lock. Not taking mmu_lock
allows multiple aging actions to run in parallel, and more importantly avoids
stalling vCPUs. This includes an implementation of per-rmap-entry locking;
aging the gfn is done with only a per-rmap single-bin spinlock taken, whereas
locking an rmap for write requires taking both the per-rmap spinlock and
the mmu_lock.
Note that this decreases slightly the accuracy of accessed-page information,
because changes to the SPTE outside aging might not use atomic operations
even if they could race against a clear of the Accessed bit. This is
deliberate because KVM and mm/ tolerate false positives/negatives for
accessed information, and testing has shown that reducing the latency of
aging is far more beneficial to overall system performance than providing
"perfect" young/old information.
* Defer runtime CPUID updates until KVM emulates a CPUID instruction, to
coalesce updates when multiple pieces of vCPU state are changing, e.g. as
part of a nested transition.
* Fix a variety of nested emulation bugs, and add VMX support for synthesizing
nested VM-Exit on interception (instead of injecting #UD into L2).
* Drop "support" for async page faults for protected guests that do not set
SEND_ALWAYS (i.e. that only want async page faults at CPL3)
* Bring a bit of sanity to x86's VM teardown code, which has accumulated
a lot of cruft over the years. Particularly, destroy vCPUs before
the MMU, despite the latter being a VM-wide operation.
* Add common secure TSC infrastructure for use within SNP and in the
future TDX
* Block KVM_CAP_SYNC_REGS if guest state is protected. It does not make
sense to use the capability if the relevant registers are not
available for reading or writing.
* Don't take kvm->lock when iterating over vCPUs in the suspend notifier to
fix a largely theoretical deadlock.
* Use the vCPU's actual Xen PV clock information when starting the Xen timer,
as the cached state in arch.hv_clock can be stale/bogus.
* Fix a bug where KVM could bleed PVCLOCK_GUEST_STOPPED across different
PV clocks; restrict PVCLOCK_GUEST_STOPPED to kvmclock, as KVM's suspend
notifier only accounts for kvmclock, and there's no evidence that the
flag is actually supported by Xen guests.
* Clean up the per-vCPU "cache" of its reference pvclock, and instead only
track the vCPU's TSC scaling (multipler+shift) metadata (which is moderately
expensive to compute, and rarely changes for modern setups).
* Don't write to the Xen hypercall page on MSR writes that are initiated by
the host (userspace or KVM) to fix a class of bugs where KVM can write to
guest memory at unexpected times, e.g. during vCPU creation if userspace has
set the Xen hypercall MSR index to collide with an MSR that KVM emulates.
* Restrict the Xen hypercall MSR index to the unofficial synthetic range to
reduce the set of possible collisions with MSRs that are emulated by KVM
(collisions can still happen as KVM emulates Hyper-V MSRs, which also reside
in the synthetic range).
* Clean up and optimize KVM's handling of Xen MSR writes and xen_hvm_config.
* Update Xen TSC leaves during CPUID emulation instead of modifying the CPUID
entries when updating PV clocks; there is no guarantee PV clocks will be
updated between TSC frequency changes and CPUID emulation, and guest reads
of the TSC leaves should be rare, i.e. are not a hot path.
x86 (Intel):
* Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and thus
modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1.
* Pass XFD_ERR as the payload when injecting #NM, as a preparatory step
for upcoming FRED virtualization support.
* Decouple the EPT entry RWX protection bit macros from the EPT Violation
bits, both as a general cleanup and in anticipation of adding support for
emulating Mode-Based Execution Control (MBEC).
* Reject KVM_RUN if userspace manages to gain control and stuff invalid guest
state while KVM is in the middle of emulating nested VM-Enter.
* Add a macro to handle KVM's sanity checks on entry/exit VMCS control pairs
in anticipation of adding sanity checks for secondary exit controls (the
primary field is out of bits).
x86 (AMD):
* Ensure the PSP driver is initialized when both the PSP and KVM modules are
built-in (the initcall framework doesn't handle dependencies).
* Use long-term pins when registering encrypted memory regions, so that the
pages are migrated out of MIGRATE_CMA/ZONE_MOVABLE and don't lead to
excessive fragmentation.
* Add macros and helpers for setting GHCB return/error codes.
* Add support for Idle HLT interception, which elides interception if the vCPU
has a pending, unmasked virtual IRQ when HLT is executed.
* Fix a bug in INVPCID emulation where KVM fails to check for a non-canonical
address.
* Don't attempt VMRUN for SEV-ES+ guests if the vCPU's VMSA is invalid, e.g.
because the vCPU was "destroyed" via SNP's AP Creation hypercall.
* Reject SNP AP Creation if the requested SEV features for the vCPU don't
match the VM's configured set of features.
Selftests:
* Fix again the Intel PMU counters test; add a data load and do CLFLUSH{OPT} on the data
instead of executing code. The theory is that modern Intel CPUs have
learned new code prefetching tricks that bypass the PMU counters.
* Fix a flaw in the Intel PMU counters test where it asserts that an event is
counting correctly without actually knowing what the event counts on the
underlying hardware.
* Fix a variety of flaws, bugs, and false failures/passes dirty_log_test, and
improve its coverage by collecting all dirty entries on each iteration.
* Fix a few minor bugs related to handling of stats FDs.
* Add infrastructure to make vCPU and VM stats FDs available to tests by
default (open the FDs during VM/vCPU creation).
* Relax an assertion on the number of HLT exits in the xAPIC IPI test when
running on a CPU that supports AMD's Idle HLT (which elides interception of
HLT if a virtual IRQ is pending and unmasked).

- Add infrastructure support to EDAC in order to be able to register memory
scrubbing RAS functionality with the kernel and expose sysfs nodes to control such scrubbing functionality.

atm: Fix NULL pointer dereference
When MPOA_cache_impos_rcvd() receives the msg, it can trigger
Null Pointer Dereference Vulnerability if both entry and
holding_time are NULL. Because there is only for the situation
where entry is NULL and holding_time exists, it can be passed
when both entry and holding_time are NULL. If these are NULL,
the entry will be passd to eg_cache_put() as parameter and
it is referenced by entry->use code in it.

net: tn40xx: add pci-id of the aqr105-based Tehuti TN4010 cards
Add the PCI-ID of the AQR105-based Tehuti TN4010 cards to allow loading of the tn40xx driver on these cards. Here, I chose the detailed definition with the subvendor ID similar to the QT2025 cards with the PCI-ID TEHUTI:0x4022, because there is a card with an AQ2104 hiding amongst the AQR105 cards, and they all come with the same PCI-ID (TEHUTI:0x4025). But the AQ2104 is currently not supported.

net: tn40xx: prepare tn40xx driver to find phy of the TN9510 card
Prepare the tn40xx driver to load for Tehuti TN9510 cards, which require bit 3 in the register TN40_REG_MDIO_CMD_STAT to be set. The function of bit 3 is unclear, but may have something to do with the length of the preamble in the MDIO communication. If bit 3 is not set, the PHY will not be found when performing a scan for PHYs. Use the available tn40_mdio_set_speed function which includes setting bit 3. Just move the function to before the devm_mdio_register function, which scans the mdio bus for PHYs.

net: tn40xx: create swnode for mdio and aqr105 phy and add to mdiobus
In case of an AQR105-based device, create a software node for the mdio function, with a child node for the Aquantia AQR105 PHY, providing a firmware-name (and a bit more, which may be used for future checks) to allow the PHY to load a MAC specific firmware from the file system. The name of the PHY software node follows the naming convention suggested in the patch for the mdiobus_scan function (in the same patch series).

net: phy: aquantia: add essential functions to aqr105 driver
This patch makes functions that were provided for aqr107 applicable to aqr105, or replaces generic functions with specific ones. Since the aqr105 was introduced before NBASE-T was defined (or 802.3bz), there are a number of vendor specific registers involved in the definition of the advertisement, in auto-negotiation and in the setting of the speed. The functions have been written following the downstream driver for TN4010 cards with aqr105 PHY, and use code from aqr107 functions wherever it seemed to make sense.

net: phy: Add swnode support to mdiobus_scan
This patch will allow to use a swnode/fwnode defined for a phy_device. The MDIO bus (mii_bus) needs to contain nodes for the PHY devices, named "ethernet-phy@i", with i being the MDIO address (0 .. PHY_MAX_ADDR - 1). The fwnode is only attached to the phy_device if there isn't already an fwnode attached. fwnode_get_named_child_node will increase the usage counter of the fwnode. However, no new code is needed to decrease the counter again, since this is already implemented in the phy_device_release function.

Merge branch 'basic-xdp-support-for-dqo-rda-queue-format'
Joshua Washington says: ==================== Basic XDP Support for DQO RDA Queue Format This patch series updates the GVE XDP infrastructure and introduces XDP_PASS and XDP_DROP support for the DQO RDA queue format. The infrastructure changes of note include an allocation path refactor for XDP queues, and a unification of RX buffer sizes across queue formats. This patch series will be followed by more patch series to introduce XDP_TX and XDP_REDIRECT support, as well as zero-copy and multi-buffer support. ==================== Link: https://patch.msgid.link/20250321002910.1343422-1-hramamurthy@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

gve: add XDP DROP and PASS support for DQ
This patch adds support for running XDP programs on DQ, along with rudimentary processing for XDP_DROP and XDP_PASS. These actions require very limited driver functionality when it comes to processing an XDP buffer, so currently if the XDP action is not XDP_PASS, the packet is dropped and stats are updated.

gve: update XDP allocation path support RX buffer posting
In order to support installing an XDP program on DQ, RX buffers need to be reposted using 4K buffers, which is larger than the default packet buffer size of 2K. This is needed to accommodate the extra head and tail that accompanies the data portion of an XDP buffer. Continuing to use 2K buffers would mean that the packet buffer size for the NIC would have to be restricted to 2048 - 320 - 256 = 1472B. However, this is problematic for two reasons: first, 1472 is not a packet buffer size accepted by GVE; second, at least 1474B of buffer space is needed to accommodate an MTU of 1460, which is the default on GCP. As such, we allocate 4K buffers, and post a 2K section of those 4K buffers (offset relative to the XDP headroom) to the NIC for DMA to avoid a potential extra copy. Because the GQ-QPL datapath requires copies regardless, this change was not needed to support XDP in that case. To capture this subtlety, a new field, packet_buffer_truesize, has been added to the rx ring struct to represent size of the allocated buffer, while packet_buffer_size has been left to represent the portion of the buffer posted to the NIC.

gve: merge packet buffer size fields
The data_buffer_size_dqo field in gve_priv and the packet_buffer_size field in gve_rx_ring theoretically have the same meaning, but they are defined in two different places and used in two separate contexts. There is no good reason for this, so this change merges those fields into the packet_buffer_size field in the RX ring. This change also introduces a packet_buffer_size field to struct gve_rx_queue_config to account for cases where queues are not allocated, such as when the interface is down.

gve: introduce config-based allocation for XDP
An earlier patch series[1] introduced RX/TX ring allocation configuration structs which contained metadata used to allocate and configure new RX and TX rings. This led to a much cleaner and safer allocation pattern wherein queue resources were not deallocated until new queue resources were successfully allocated. Migrate the XDP allocation path to use the same pattern to allow for the existence of a single allocation path instead of relying on XDP-specific allocation methods. These extra allocation methods result in the duplication of many existing behaviors while being prone to error when configuration changes unrelated to XDP occur.

On ILK-IVB only PCH outputs use shared dplls. Move the relevant intel_disable_shared_dpll() into ilk_pch_post_disable() to make that clear (and if we extend the dpll mgr to cover all plls we need different enable/disable points anyway for the PCH vs. CPU eDP cases).

thermal/drivers/mediatek/lvts: Only update IRQ enable for valid sensors
Only sensors that are valid need to have their interrupts enable status updated based on their thresholds. Use the lvts_for_each_valid_sensor() helper in lvts_update_irq_mask() to ignore invalid sensors. Currently, since the invalid sensors will always contain zeroed out thresholds (from kzalloc), they will always get their interrupts disabled on this loop. So this commit doesn't change the resulting interrupts configuration, but it slightly optimizes the loop by skipping the invalid sensors, avoids potential future surprises if at some point memory is no longer allocated for invalid sensors, as well as makes the code more obvious.

thermal/drivers/mediatek/lvts: Disable low offset IRQ for minimum threshold
In order to get working interrupts, a low offset value needs to be
configured. The minimum value for it is 20 Celsius, which is what is
configured when there's no lower thermal trip (ie the thermal core
passes -INT_MAX as low trip temperature). However, when the temperature
gets that low and fluctuates around that value it causes an interrupt
storm.
Prevent that interrupt storm by not enabling the low offset interrupt if
the low threshold is the minimum one.

thermal/drivers/mediatek/lvts: Disable Stage 3 thermal threshold
The Stage 3 thermal threshold is currently configured during
the controller initialization to 105 Celsius. From the kernel
perspective, this configuration is harmful because:
* The stage 3 interrupt that gets triggered when the threshold is
crossed is not handled in any way by the IRQ handler, it just gets
cleared. Besides, the temperature used for stage 3 comes from the
sensors, and the critical thermal trip points described in the
Devicetree will already cause a shutdown when crossed (at a lower
temperature, of 100 Celsius, for all SoCs currently using this
driver).
* The only effect of crossing the stage 3 threshold that has been
observed is that it causes the machine to no longer be able to enter
suspend. Even if that was a result of a momentary glitch in the
temperature reading of a sensor (as has been observed on the
MT8192-based Chromebooks).
For those reasons, disable the Stage 3 thermal threshold configuration.

thermal/drivers/mediatek/lvts: Disable monitor mode during suspend
When configured in filtered mode, the LVTS thermal controller will
monitor the temperature from the sensors and trigger an interrupt once a
thermal threshold is crossed.
Currently this is true even during suspend and resume. The problem with
that is that when enabling the internal clock of the LVTS controller in
lvts_ctrl_set_enable() during resume, the temperature reading can glitch
and appear much higher than the real one, resulting in a spurious
interrupt getting generated.
Disable the temperature monitoring and give some time for the signals to
stabilize during suspend in order to prevent such spurious interrupts.

thermal/drivers/rockchip: Add missing rk3328 mapping entry
The mapping table for the rk3328 is missing the entry for -25C which is
found in the TRM section 9.5.2 "Temperature-to-code mapping".
NOTE: the kernel uses the tsadc_q_sel=1'b1 mode which is defined as:
4096-<code in table>. Whereas the table in the TRM gives the code
"3774" for -25C, the kernel uses 4096-3774=322.
[Dragan Simic] : "After going through the RK3308 and RK3328 TRMs, as
well as through the downstream kernel code, it seems we may have
some troubles at our hands. Let me explain, please.
To sum it up, part 1 of the RK3308 TRM v1.1 says on page 538 that
the equation for the output when tsadc_q_sel equals 1 is (4096 -
tsadc_q), while part 1 of the RK3328 TRM v1.2 says that the output
equation is (1024 - tsadc_q) in that case.
The downstream kernel code, however, treats the RK3308 and RK3328
tables and their values as being the same. It even mentions 1024 as
the "offset" value in a comment block for the rk_tsadcv3_control()
function, just like the upstream code does, which is obviously wrong
"offset" value when correlated with the table on page 544 of part 1
of the RK3308 TRM v1.1.
With all this in mind, it's obvious that more work is needed to make
it clear where's the actual mistake (it could be that the TRM is
wrong), which I'll volunteer for as part of the SoC binning project.
In the meantime, this patch looks fine as-is to me, by offering
what's a clear improvement to the current state of the upstream
code"

thermal/drivers/tsens: Add TSENS enable and calibration support for V2
SoCs without RPM need to enable sensors and calibrate them from the kernel. The IPQ5332 and IPQ5424 use the tsens v2.3.3 IP and do not have RPM. Therefore, add a new calibration function for V2, as the tsens.c calib function only supports V1. Also add new feature_config, ops and data for IPQ5332, IPQ5424. Although the TSENS IP supports 16 sensors, not all are used. The hw_id is used to enable the relevant sensors.

The IPQ5332 and IPQ5424 use TSENS v2.3.3 IP with combined interrupt. RPM is not available in these SoCs, hence adding new compatible to have the sensor enablement and calibration function.
