This patch adds support for a new feature, named "Interrupt Delay",
allowing driver to set a specific delay time for next interrupt
detection. It gives driver a capability to control THC waiting time for
the next interrupt, to reduce the likelihood of spurious readings.
APIs added:
- thc_i2c_set_rx_int_delay(): Set I2C Rx input interrupt delay value
- thc_i2c_rx_int_delay_enable(): Enable or disable I2C Rx interrupt delay
As this interrupt delay feature is only applicable to RxDMA and must
remain disabled during SWDMA operations, it also involves a change
in SWDMA code to record the max input size control feature state
before SWDMA and restore the state after SWDMA.

This patch adds support for a new feature, named "Max Input Size
Control", allowing driver to set a maximum input size for RxDMA. This
enhancement aims to prevent RxDMA buffer overruns caused by data
corruption on the I2C bus, thereby improving overall system stability.
APIs added:
- thc_i2c_set_rx_max_size(): Set the maximum input size for I2C RxDMA.
- thc_i2c_rx_max_size_enable(): Enable or disable the max input size
control.
As this max input size control feature is only applicable to RxDMA
and must remain disabled during SWDMA operations, it also involves
a change in SWDMA code to record the max input size control feature
state before SWDMA and restore the state after SWDMA.

Pull fuse updates from Miklos Szeredi:
- Remove tmp page copying in writeback path (Joanne).
This removes ~300 lines and with that a lot of complexity related to
avoiding reclaim related deadlock. The old mechanism is replaced with
a mapping flag that tells the MM not to block reclaim waiting for
writeback to complete. The MM parts have been reviewed/acked by
respective maintainers.
- Convert more code to handle large folios (Joanne). This still just
adds the code to deal with large folios and does not enable them yet.
- Allow invalidating all cached lookups atomically (Luis Henriques).
This feature is useful for CernVMFS, which currently does this
iteratively.

different nodes of a distributed fs (Guang Yuan Wu)
- Update documentation for passthrough (Chen Linxuan)

Pull more kvm updates from Paolo Bonzini:
Generic:
- Clean up locking of all vCPUs for a VM by using the *_nest_lock()
family of functions, and move duplicated code to virt/kvm/. kernel/
patches acked by Peter Zijlstra
- Add MGLRU support to the access tracking perf test
ARM fixes:
- Make the irqbypass hooks resilient to changes in the GSI<->MSI
routing, avoiding behind stale vLPI mappings being left behind. The
fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
and nuking the vLPI mapping upon a routing change
- Close another VGIC race where vCPU creation races with VGIC
creation, leading to in-flight vCPUs entering the kernel w/o
private IRQs allocated
- Fix a build issue triggered by the recently added workaround for
Ampere's AC04_CPU_23 erratum
- Correctly sign-extend the VA when emulating a TLBI instruction
potentially targeting a VNCR mapping
- Avoid dereferencing a NULL pointer in the VGIC debug code, which
can happen if the device doesn't have any mapping yet
s390:
- Fix interaction between some filesystems and Secure Execution
- Some cleanups and refactorings, preparing for an upcoming big
series
x86:
- Wait for target vCPU to ack KVM_REQ_UPDATE_PROTECTED_GUEST_STATE
to fix a race between AP destroy and VMRUN
- Decrypt and dump the VMSA in dump_vmcb() if debugging enabled for
the VM
- Refine and harden handling of spurious faults
- Add support for ALLOWED_SEV_FEATURES
- Add #VMGEXIT to the set of handlers special cased for
CONFIG_RETPOLINE=y
- Treat DEBUGCTL[5:2] as reserved to pave the way for virtualizing
features that utilize those bits
- Don't account temporary allocations in sev_send_update_data()
- Add support for KVM_CAP_X86_BUS_LOCK_EXIT on SVM, via Bus Lock
Threshold
- Unify virtualization of IBRS on nested VM-Exit, and cross-vCPU
IBPB, between SVM and VMX
- Advertise support to userspace for WRMSRNS and PREFETCHI
- Rescan I/O APIC routes after handling EOI that needed to be
intercepted due to the old/previous routing, but not the
new/current routing
- Add a module param to control and enumerate support for device
posted interrupts
- Fix a potential overflow with nested virt on Intel systems running
32-bit kernels
- Flush shadow VMCSes on emergency reboot
- Add support for SNP to the various SEV selftests
- Add a selftest to verify fastops instructions via forced emulation
- Refine and optimize KVM's software processing of the posted
interrupt bitmap, and share the harvesting code between KVM and the
kernel's Posted MSI handler"

Pull MTD updates from Miquel Raynal:
"A big core MTD change is the introduction of a new class to always
register a master device. This is a problem that has been there
forever: the "master" device was not always present depending on a
number of heuristics such as the presence of fixed partitions and the
absence of a Kconfig symbol to force its presence. This was a problem
for runtime PM operations which might not have the "master" device
available in all situation.
The SPI NAND subsystem has seen the introduction of DTR operations
(the equivalent of DDR transfers), which involved quite a few
preparation patches for clarifying macro names.
In the raw NAND subsystem, the brcmnand driver has been "fixed" for
old legacy SoCs with an update of the ->exec_op() hook, there has been
the introduction of a new controller driver named Loongson-1, and the
Qualcomm driver has received quite a few misc fixes as well as a new
compatible.
Finally, Macornix SPI NOR entries have been cleaned-up and some SFDP
table fixups for Macronix MX25L3255E have been merged.
Aside from this, there is the usual load of misc improvement, fixes,
and yaml conversion"

SPI NOR changes for 6.16
Notable changes:
- Cleanup some Macronix flash entries.
- Add SFDP table fixups for Macronix MX25L3255E.
|
|
https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for 6.16, take #1
- Make the irqbypass hooks resilient to changes in the GSI<->MSI
routing, avoiding behind stale vLPI mappings being left behind. The
fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
and nuking the vLPI mapping upon a routing change.
- Close another VGIC race where vCPU creation races with VGIC
creation, leading to in-flight vCPUs entering the kernel w/o private
IRQs allocated.
- Fix a build issue triggered by the recently added workaround for
Ampere's AC04_CPU_23 erratum.
- Correctly sign-extend the VA when emulating a TLBI instruction
potentially targeting a VNCR mapping.
- Avoid dereferencing a NULL pointer in the VGIC debug code, which can
happen if the device doesn't have any mapping yet.

Commit fb49f07ba1d9 ("locking/mutex: implement mutex_lock_killable_nest_lock")
changed the set of functions that mutex.c defines when CONFIG_DEBUG_LOCK_ALLOC
is set.
- it removed the "extern" declaration of mutex_lock_killable_nested from
include/linux/mutex.h, and replaced it with a macro since it could be
treated as a special case of _mutex_lock_killable. It also removed a
definition of the function in kernel/locking/mutex.c.
- likewise, it replaced mutex_trylock() with the more generic
mutex_trylock_nest_lock() and replaced mutex_trylock() with a macro.
However, it left the old definitions in place in kernel/locking/rtmutex_api.c,
which causes failures when building with CONFIG_RT_MUTEXES=y. Bring over
the changes.

While not yet in the tree, there is a proposed patch[1] that was
depending on the prior behavior of _DEFINE_FLEX, which did not have an
explicit initializer. Provide this via __DEFINE_FLEX now, which can also
have attributes applied (e.g. __uninitialized).
Examples of the resulting initializer behaviors can be seen here:

When executing "modprobe iTCO_wdt heartbeat=700", the user-specified
'heartbeat' parameter exceeds the valid range, the driver clamps the
timeout to default 30s but fails to update the logged 'heartbeat' value,
resulting in misleading log output:
iTCO_wdt iTCO_wdt: timeout value out of range, using 30
iTCO_wdt iTCO_wdt: initialized. heartbeat=700 sec (nowayout=0)
After validating the range, update the 'heartbeat' value with the clamped
timeout value to ensure that log messages accurately reflect the actual
runtime parameters.

Add a driver for the Intel Over-Clocking Watchdog found in Intel
Platform Controller (PCH) chipsets. This watchdog is controlled
via a simple single-register interface and would otherwise be
standard except for the presence of a LOCK bit that can only be
