up to: 8278fd6006a0: LoongArch: entry: Fix include order
Updates for the generic and architecture entry code:
- Move LoongArch and RISC-V ret_from_fork() implementations to C code so
that syscall_exit_user_mode() can be inlined.
- Split the RISC-V ret_from_fork() implementation into return to user and
return to kernel, which gives a measurable performance improvement.
- Inline syscall_exit_user_mode() which benefits all architectures by
avoiding a function call and letting the compiler do better
optimizations.
Thanks,
tglx

up to: a510bb87da72: genirq/irqdesc: Remove double locking in hwirq_show()
Updates for the generic interrupt subsystem core code:
- Address a long standing subtle problem in the CPU hotplug code for
affinity-managed interrupts.
Affinity-managed interrupts are shut down by the core code when the
last CPU in the affinity set goes offline and started up again when the
first CPU in the affinity set becomes online again. This unfortunately
does not take into account whether an interrupt has been disabled
before the last CPU goes offline and starts up the interrupt
unconditionally when the first CPU becomes online again. That's
obviously not what drivers expect.
Address this by preserving the disabled state for affinity-managed
interrupts accross these CPU hotplug operations. All non-managed
interrupts are not affected by this because startup/shutdown is coupled
to request/free_irq() which obviously has to reset state.
- Support three-cell scheme interrupts to allow GPIO drivers to specify
interrupts from an already existing scheme
- Switch the interrupt subsystem core to lock guards. This gets rid of
quite some copy & pasta boilerplate code all over the place.
- The usual small cleanups and improvements all over the place
Thanks,
tglx

From: Thomas Gleixner @ 2025-05-25 20:53 UTC (permalink / raw)
To: Linus Torvalds; +Cc: linux-kernel, x86
Linus,
please pull the latest irq/cleanups branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-cleanups-2025-05-25
up to: 38c1e73fdeb3: irqdomain: Consolidate coding style
A set of cleanups for the generic interrupt subsystem:
- Consolidate on one set of functions for the interrupt domain code to
get rid of pointlessly duplicated code with only marginal different
semantics.
- Update the documentation accordingly and consolidate the coding style
of the irqdomain header.
Note: This pulls in a commit (branch) from the PCI tree and the first
commit or the tip irq/core branch (which already has been sent to
you) to avoid merge conflicts.
Thanks,
tglx

-An interrupt controller driver creates and registers an irq_domain by

-The function will return a pointer to the irq_domain on success. The caller

+struct irq_domain could be defined as an irq domain controller. That
+is, it handles the mapping between hardware and virtual interrupt
+numbers for a given interrupt domain. The domain structure is
+generally created by the PIC code for a given PIC instance (though a
+domain can cover more than one PIC if they have a flat number model).
+It is the domain callbacks that are responsible for setting the
+irq_chip on a given irq_desc after it has been mapped.
+
+The host code and data structures use a fwnode_handle pointer to
+identify the domain. In some cases, and in order to preserve source
+code compatibility, this fwnode pointer is "upgraded" to a DT
+device_node. For those firmware infrastructures that do not provide a
+unique identifier for an interrupt controller, the irq_domain code
+offers a fwnode allocator.

In most cases, the irq_domain will begin empty without any mappings

up to: 3e402acd5c4f: irqchip/irq-pruss-intc: Simplify chained interrupt handler setup
Update for interrupt chip drivers:
- Convert the generic interrupt chip to lock guards to remove copy &
pasta boilerplate code and gotos.
- A new driver fot the interrupt controller in the EcoNet EN751221 MIPS SoC.
- Extend the SG2042-MSI driver to support the new SG2044 SoC
- Updates and cleanups for the (ancient) VT8500 driver
- Improve the scalability of the ARM GICV4.1 ITS driver by utilizing node
local copies a VM's interrupt translation table when possible. This
results in a 12% reduction of VM IPI latency in certain workloads.
- The usual cleanups and improvements all over the place
Thanks,
tglx

+
+description:
+ The EcoNet EN751221 Interrupt Controller is a simple interrupt controller
+ designed for the MIPS 34Kc MT SMP processor with 2 VPEs. Each interrupt can
+ be routed to either VPE but not both, so to support per-CPU interrupts, a
+ secondary IRQ number is allocated to control masking/unmasking on VPE#1. For
+ lack of a better term we call these "shadow interrupts". The assignment of
+ shadow interrupts is defined by the SoC integrator when wiring the interrupt
+ lines, so they are configurable in the device tree.

+ when VPE#1 requests IRQ 8, it will manipulate the IRQ 3 mask bit.

+ * EN751221 Interrupt Controller Driver.
+ *
+ * The EcoNet EN751221 Interrupt Controller is a simple interrupt controller
+ * designed for the MIPS 34Kc MT SMP processor with 2 VPEs. Each interrupt can
+ * be routed to either VPE but not both, so to support per-CPU interrupts, a
+ * secondary IRQ number is allocated to control masking/unmasking on VPE#1. In
+ * this driver, these are called "shadow interrupts". The assignment of shadow
+ * interrupts is defined by the SoC integrator when wiring the interrupt lines,
+ * so they are configurable in the device tree.
+ *
+ * If an interrupt (say 30) needs per-CPU capability, the SoC integrator
+ * allocates another IRQ number (say 29) to be its shadow. The device tree
+ * reflects this by adding the pair <30 29> to the "econet,shadow-interrupts"
+ * property.
+ *
+ * When VPE#1 requests IRQ 30, the driver manipulates the mask bit for IRQ 29,
+ * telling the hardware to mask VPE#1's view of IRQ 30.
+ *

Linus,
please pull the latest irq/msi branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-msi-2025-05-25
up to: 4e7bca76e3fe: PCI/MSI: Use bool for MSI enable state tracking
Updates for the MSI subsystem (core code and PCI):
- Switch the MSI decriptor locking to lock guards
- Replace a broken and naive implementation of PCI/MSI-X control word
updates in the PCI/TPH driver with a properly serialized variant in the
PCI/MSI core code.
- Remove the MSI descriptor abuse in the SCCI/UFS/QCOM driver by
replacing the direct access to the MSI descriptors with the proper API
function calls. People will never understand that APIs exist for a
reason...
- Provide core infrastructre for the upcoming PCI endpoint library
extensions. Currently limited to ARM GICv3+, but in theory extensible
to other architectures.
- Provide a MSI domain::teardown() callback, which allows drivers to undo
the effects of the prepare() callback.
- Move the MSI domain::prepare() callback invocation to domain creation
time to avoid redundant (and in case of ARM/GIC-V3-ITS confusing)
invocations on every allocation.
In combination with the new teardown callback this removes some ugly
hacks in the GIC-V3-ITS driver, which pretended to work around the
short comings of the core code so far. With this update the code is
correct by design and implementation.
- Make the irqchip MSI library globally available, provide a MSI parent
domain creation helper and convert a bunch of (PCI/)MSI drivers over to
the modern MSI parent mechanism. This is the first step to get rid of
at least one incarnation of the three PCI/MSI management schemes.
- The usual small cleanups and improvements
Thanks,
tglx

+ Maps a Device ID to an MSI and associated MSI specifier data.
+
+ A PCI Endpoint (EP) can use MSI as a doorbell function. This is achieved by
+ mapping the MSI controller's address into PCI BAR<n>. The PCI Root Complex
+ can write to this BAR<n>, triggering the EP to generate IRQ. This notifies
+ the EP-side driver of an event, eliminating the need for the driver to
+ continuously poll for status changes.
+
+ However, the EP cannot rely on Requester ID (RID) because the RID is
+ determined by the PCI topology of the host system. Since the EP may be
+ connected to different PCI hosts, the RID can vary between systems and is
+ therefore not a reliable identifier.
+
+ Each EP can support up to 8 physical functions and up to 65,536 virtual
+ functions. To uniquely identify each child device, a device ID is defined
+ as
+ - Bits [2:0] for the function number (func)
+ - Bits [18:3] for the virtual function index (vfunc)
+
+ The resulting device ID is computed as:
+
+ (func & 0x7) | (vfunc << 3)
+
+ The property is an arbitrary number of tuples of
+ (device-id-base, msi, msi-base,length).
+
+ Any Device ID id in the interval [id-base, id-base + length) is
+ associated with the listed MSI, with the MSI specifier
+ (id - id-base + msi-base).

To: Linus Torvalds; +Cc: linux-kernel, x86
Linus,
please pull the latest timers/cleanups branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-cleanups-2025-05-25
up to: aad823aa3a7d: treewide, timers: Rename destroy_timer_on_stack() as timer_destroy_on_stack()
Another set of timer API cleanups:
- Convert init_timer*(), try_to_del_timer_sync() and
destroy_timer_on_stack() over to the canonical timer_*() namespace
convention.
There are is another large converstion pending, which has not been included
because it would have caused a gazillion of merge conflicts in next. The
conversion scripts will be run towards the end of the merge window and a
pull request sent once all conflict dependencies have been merged.
Thanks,
tglx

Linus,
please pull the latest timers/clocksource branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-clocksource-2025-05-25
up to: 29857e6f4e30: Merge tag 'timers-v6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/daniel.lezcano/linux into timers/drivers
Updates for clocksource/clockevent drivers:
- The final conversion of text formatted device tree binding to schemas.
- A new driver fot the System Timer Module on S32G NXP SoCs.
- A new driver fot the Econet HPT timer
- The usual improvements and device tree binding updates
Thanks,
tglx

From: Thomas Gleixner @ 2025-05-25 20:53 UTC (permalink / raw)
To: Linus Torvalds; +Cc: linux-kernel, x86
Linus,
please pull the latest timers/core branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-core-2025-05-25
up to: 6c58d2791d60: tick/nohz: Remove unused tick_nohz_full_add_cpus_to()
Updates for the time/timer core code:
- Rework the initialization of the posix-timer kmem_cache and move the
cache pointer into the timer_data structure to prevent false sharing.
- Switch the alarmtimer code to lock guards.
- Improve the CPU selection criteria in the per CPU validation of the
clocksource watchdog to avoid arbitrary selections (or omissions) on
systems with a small number of CPUs.
- The usual cleanups and improvements
Thanks,
tglx

Linus,
please pull the latest timers/cleanups branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-cleanups-2025-06-08
up to: 41cb08555c41: treewide, timers: Rename from_timer() to timer_container_of()
The delayed from_timer() API cleanup:
The renaming to the timer_*() namespace was delayed due massive conflicts
against Linux-next. Now that everything is upstream finish the conversion.
Thanks,
tglx
