bpf: Implement mprog API on top of existing cgroup progs
Current cgroup prog ordering is appending at attachment time. This is not ideal. In some cases, users want specific ordering at a particular cgroup level. To address this, the existing mprog API seems an ideal solution with supporting BPF_F_BEFORE and BPF_F_AFTER flags. But there are a few obstacles to directly use kernel mprog interface. Currently cgroup bpf progs already support prog attach/detach/replace and link-based attach/detach/replace. For example, in struct bpf_prog_array_item, the cgroup_storage field needs to be together with bpf prog. But the mprog API struct bpf_mprog_fp only has bpf_prog as the member, which makes it difficult to use kernel mprog interface. In another case, the current cgroup prog detach tries to use the same flag as in attach. This is different from mprog kernel interface which uses flags passed from user space. So to avoid modifying existing behavior, I made the following changes to support mprog API for cgroup progs: - The support is for prog list at cgroup level. Cross-level prog list (a.k.a. effective prog list) is not supported. - Previously, BPF_F_PREORDER is supported only for prog attach, now BPF_F_PREORDER is also supported by link-based attach. - For attach, BPF_F_BEFORE/BPF_F_AFTER/BPF_F_ID/BPF_F_LINK is supported similar to kernel mprog but with different implementation. - For detach and replace, use the existing implementation. - For attach, detach and replace, the revision for a particular prog list, associated with a particular attach type, will be updated by increasing count by 1.

cgroup: Add bpf prog revisions to struct cgroup_bpf
One of key items in mprog API is revision for prog list. The revision number will be increased if the prog list changed, e.g., attach, detach or replace. Add 'revisions' field to struct cgroup_bpf, representing revisions for all cgroup related attachment types. The initial revision value is set to 1, the same as kernel mprog implementations.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)
- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)
Resource management:
- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)
- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)
- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)
- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)
Error handling:
- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)
- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)
- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)
- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)
Power management:
- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)
- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)
Power control:
- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)
- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)
Bandwidth control:
- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)
- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)
PCIe native device hotplug:
- Ignore Presence Detect Changed caused by DPC.
pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset.
On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)
Virtualization:
- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)
Endpoint framework:
- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)
- Simplify ctrl/SPAD space allocation and avoid allocating more space
than needed (Jerome Brunet)
- Correct MSI-X PBA offset calculations for DesignWare and Cadence
endpoint controllers (Niklas Cassel)
- Align the return value (number of interrupts) encoding for
pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)
- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)
Common host controller library:
- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)
- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
varying capabilities (Marc Zyngier)
- Skip ports disabled in DT when setting up ports (Janne Grunau)
- Add t6020 compatible string (Alyssa Rosenzweig)
- Add T602x PCIe support (Hector Martin)
- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)
- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)
- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)
- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)
Cadence PCIe controller driver:
- Drop a runtime PM 'put' to resolve a runtime atomic count underflow
(Hans Zhang)
- Make the cadence core buildable as a module (Kishon Vijay Abraham I)
- Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
loadable drivers when they are removed (Siddharth Vadapalli)
Freescale i.MX6 PCIe controller driver:
- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)
- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)
- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)
- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)
- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)
- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)
- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)
Mobiveil PCIe controller driver:
- Return bool (not int) for link-up check in
mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
Zhang)
NVIDIA Tegra194 PCIe controller driver:
- Create debugfs directory for 'aspm_state_cnt' only when
CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
Zhang)
Qualcomm PCIe controller driver:
- Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
equalization presets (Krishna Chaitanya Chundru)
- Read Maximum Link Width from the Link Capabilities register if DT
lacks 'num-lanes' property (Krishna Chaitanya Chundru)
- Add Physical Layer 64 GT/s Capability ID and register offsets for
8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
Chundru)
- Add generic dwc support for configuring lane equalization presets
(Krishna Chaitanya Chundru)
- Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)
Renesas R-Car PCIe controller driver:
- Describe endpoint BAR 4 as being fixed size (Jerome Brunet)
- Document how to obtain R-Car V4H (r8a779g0) controller firmware
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)
- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)
Rockchip DesignWare PCIe controller driver:
- Check only PCIE_LINKUP, not LTSSM status, to determine whether the
link is up (Shawn Lin)
- Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
for Root Complex and Endpoint modes (Shawn Lin)
- Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
resets non-sticky registers (Shawn Lin)
- Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
(Diederik de Haas)
Synopsys DesignWare PCIe controller driver:
- Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
more robust; this will not affect the intended link width if all
lanes are functional (Wenbin Yao)
- Return bool (not int) for link-up check in dw_pcie_ops.link_up()
and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
tegra194, uniphier, visconti (Hans Zhang)
- Add debugfs support for exposing DWC device-specific PTM context
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Make j721e buildable as a loadable and removable module (Siddharth
Vadapalli)
- Fix j721e host/endpoint dependencies that result in link failures
in some configs (Arnd Bergmann)
Device tree bindings:
- Add qcom DT binding for 'global' interrupt (PCIe controller and
link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan

tracing fixes:
- Fix UAF in module unload in ftrace when there's a bug in the module If a module is buggy and triggers ftrace_disable which is set when an anomaly is detected, when it gets unloaded it doesn't free the hooks into kallsyms, and when a kallsyms lookup is performed it may access the mod->modname field and crash via UAF. Fix this by still freeing the mod_maps that are attached to kallsyms on module unload regardless if ftrace_disable is set or not. - Do not bother allocating mod_maps for kallsyms if ftrace_disable is set - Remove unused trace events When a trace event or tracepoint is created but not used, it still creates the code and data structures needed for that trace event. This just wastes memory.

Backlight for v6.16
* Framebuffer Subsystem (fbdev):
* The display's blanking status is now tracked in `struct fb_info`
* `framebuffer_alloc()` initializes the blank state to `FB_BLANK_UNBLANK`
* `register_framebuffer()` sets the state to `FB_BLANK_POWERDOWN` if an `fb_blank`
callback exists, ensuring `FB_EVENT_BLANK` listeners correctly see the display
being turned on during the first modeset
* The `FB_EVENT_BLANK` event data now includes both the new and the old blank states
* Qualcomm WLED Backlight:
* Added a NULL check after `devm_kasprintf()` in `wled_configure()` to prevent a
potential NULL pointer dereference if memory allocation fails
* Framebuffer Subsystem (fbdev):
* `fb_blank()` has been reworked to return early on errors, without functional
changes, in preparation for further state tracking improvements
* Fbdev now calls dedicated functions in the backlight subsystems to notify them
of blank state changes, instead of relying on fbdev event notifiers
* For LCDs, fbdev also calls a dedicated function to notify of mode changes
* Backlight Subsystem:
* Implemented fbdev blank state tracking using the (newly enhanced) blank state
information provided directly by `FB_EVENT_BLANK`
* Removed internal blank state tracking fields (`fb_bl_on`) from
`struct backlight_device`
* Moved the handling of blank-state updates into a separate internal helper
function, `backlight_notify_blank()`
* Removed support for fbdev events and replaced it with a dedicated function call
interface (`backlight_notify_blank()` and `backlight_notify_blank_all()`) for
display drivers to update backlight status
* LCD Subsystem:
* Moved the handling of display updates (blank events and mode changes) from
fbdev event notifiers to separate internal helper functions (`lcd_notify_blank`,
`lcd_notify_mode_change`)
* Removed support for fbdev events and replaced it with dedicated function call
interfaces (`lcd_notify_blank_all()`, `lcd_notify_mode_change_all()`)

fsdax: Remove unused trace events for dax insert mapping
When the dax_fault_actor() helper was factored out, it removed the calls
to the dax_pmd_insert_mapping and dax_insert_mapping events but never
removed the events themselves. As each event created takes up memory
(roughly 5K each), this is a waste as it is never used.
Remove the unused dax_pmd_insert_mapping and dax_insert_mapping trace
events.

Merge tag 'mfd-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd
Pull MFD updates from Lee Jones:
"Samsung Exynos ACPM:
- Populate child platform devices from device tree data
- Introduce a new API, 'devm_acpm_get_by_node()', for child devices
to get the ACPM handle
ROHM PMICs:
- Add support for the ROHM BD96802 scalable companion PMIC to the
BD96801 core driver
- Add support for controlling the BD96802 using the BD96801 regulator
driver
- Add support to the BD96805, which is almost identical to the
BD96801
- Add support to the BD96806, which is similar to the BD96802
Maxim MAX77759:
- Add a core driver for the MAX77759 companion PMIC
- Add a GPIO driver for the expander functions on the MAX77759
- Add an NVMEM driver to expose the non-volatile memory on the
MAX77759
STMicroelectronics STM32MP25:
- Add support for the STM32MP25 SoC to the stm32-lptimer
- Add support for the STM32MP25 to the clocksource driver, handling
new register access requirements
- Add support for the STM32MP25 to the PWM driver, enabling up to two
PWM outputs
Broadcom BCM590xx:
- Add support for the BCM59054 PMU
- Parse the PMU ID and revision to support behavioral differences
between chip revisions
- Add regulator support for the BCM59054
Samsung S2MPG10:
- Add support for the S2MPG10 PMIC, which communicates via the
Samsung ACPM firmware instead of I2C
Exynos ACPM:
- Improve timeout detection reliability by using ktime APIs instead
of a loop counter assumption
- Allow PMIC access during late system shutdown by switching to
'udelay()' instead of a sleeping function
- Fix an issue where reading command results longer than 8 bytes
would fail
- Silence non-error '-EPROBE_DEFER' messages during boot to clean up
logs
Exynos LPASS:
- Fix an error handling path by switching to
'devm_regmap_init_mmio()' to prevent resource leaks
- Fix a bug where 'exynos_lpass_disable()' was called twice in the
remove function
- Fix another resource leak in the probe's error path by using
'devm_add_action_or_reset()'
Samsung SEC:
- Handle the s2dos05, which does not have IRQ support, explicitly to
prevent warnings
- Fix the core driver to correctly handle errors from
'sec_irq_init()' instead of ignoring them
STMPE-SPI:
- Correct an undeclared identifier in the 'MODULE_DEVICE_TABLE' macro
MAINTAINERS:
- Adjust a file path for the Siemens IPC LED drivers entry to fix a
broken reference
Maxim Drivers:
- Correct the spelling of "Electronics" in Samsung copyright headers
across multiple files
General:
- Fix wakeup source memory leaks on device unbind for 88pm886,
as3722, max14577, max77541, max77705, max8925, rt5033, and
sprd-sc27xx drivers
Samsung SEC Drivers:
- Split the driver into a transport-agnostic core ('sec-core') and
transport-specific ('sec-i2c', 'sec-acpm') modules to support
non-I2C devices
- Merge the 'sec-core' and 'sec-irq' modules to reduce memory
consumption
- Move internal APIs to a private header to clean up the public API
- Improve code style by sorting includes, cleaning up headers,
sorting device tables, and using helper macros like
'dev_err_probe()', 'MFD_CELL', and 'REGMAP_IRQ_REG'
- Make regmap configuration for s2dos05/s2mpu05 explicit to improve
clarity
- Rework platform data and regmap instantiation to use OF match data
instead of a large switch statement
ROHM BD96801/2:
- Prepare the driver for new models by separating chip-specific data
into its own structure
- Drop IC name prefix from IRQ resource names in both the MFD and
regulator drivers for simplification
Broadcom BCM590xx:
- Refactor the regulator driver to store descriptions in a table to
ease support for new chips
- Rename BCM59056-specific data to prepare for the addition of other
regulators
- Use 'dev_err_probe()' for cleaner error handling
Exynos ACPM:
- Correct kerneldoc warnings and use the conventional 'np' argument
name
General MFD:
- Convert 'aat2870' and 'tps65010' to use the per-client debugfs
directory provided by the I2C core
- Convert 'sm501', 'tps65010' and 'ucb1x00' to use the new GPIO line
value setter callbacks
- Constify 'regmap_irq_chip' and other structures in '88pm886' to
move data to read-only sections
BCM590xx:
- Drop the unused "id" member from the 'bcm590xx' struct in
preparation for a replacement
Samsung SEC Core:
- Remove forward declarations for functions that no longer exist
SM501:
- Remove the unused 'sm501_find_clock()' function
New Compatibles:
- Google: Add a PMIC child node to the 'google,gs101-acpm-ipc'
binding
- ROHM: Add new bindings for 'rohm,bd96802-regulator' and
'rohm,bd96802-pmic', and add compatibles for BD96805 and BD96806
- Maxim: Add new bindings for 'maxim,max77759-gpio',
'maxim,max77759-nvmem', and the top-level 'maxim,max77759'

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).

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 acknowledge 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

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. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmg91NEACgkQJWrqGEe9 VoR8egf+JPTtykQ+Bip9bHStgfpxi0+OKL81PUuPBsbs5C546u5t6ZRhoPsU+KqL ZTyUk3ys7HcSwZCuiS9V6ea6TNV1FvAVZm+ONpkuPnU60++z8YfVr8ZvtgT0IUXx COi+5ksdsTFZMyRG+VybRKnYNrTYB7j7CqVL8ifxq1XYWnYdhjy5PH4DgAKnBhGL 523kN2eR85AhvJ4aulsKbcqQQYKvJIQbhjAKklA3yQVarDmoOdiSmndoZlRy+MDu B9DaRMvRRa/g1nI0stvR9K7FtdSrMYTg4kowR9jPRx0zEZXFFsZbASgcC+3G7HdK 7rLFWrN+G6fitcEjeAnfyV+sKF48LA== =tW1t -----END PGP SIGNATURE----- Merge tag 'mtd/for-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux Pull MTD updates from Miquel Raynal: "A big core MTD change is the introduction of a new class to always register a master device.

xdp: Remove unused mem_return_failed event
The change to allow page_pool to handle its own page destruction instead
of relying on XDP removed the trace_mem_return_failed() tracepoint caller,
but did not remove the mem_return_failed trace event. As trace events take
up memory when they are created regardless of if they are used or not,
having this unused event around wastes around 5K of memory.
Remove the unused event.

- Make the irqbypass hooks resilient to changes in the GSI<->MSI routing, avoiding behind stale vLPI mappings being left behind.

overflow: Introduce __DEFINE_FLEX for having no initializer
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:

sched/numa: add statistics of numa balance task
On systems with NUMA balancing enabled, it has been found that tracking
task activities resulting from NUMA balancing is beneficial. NUMA
balancing employs two mechanisms for task migration: one is to migrate
a task to an idle CPU within its preferred node, and the other is to
swap tasks located on different nodes when they are on each other's
preferred nodes.
The kernel already provides NUMA page migration statistics in
/sys/fs/cgroup/mytest/memory.stat and /proc/{PID}/sched. However, it
lacks statistics regarding task migration and swapping. Therefore,
relevant counts for task migration and swapping should be added.
The following two new fields:
numa_task_migrated
numa_task_swapped
will be shown in /sys/fs/cgroup/{GROUP}/memory.stat, /proc/{PID}/sched
and /proc/vmstat.
Introducing both per-task and per-memory cgroup (memcg) NUMA balancing
statistics facilitates a rapid evaluation of the performance and
resource utilization of the target workload. For instance, users can
first identify the container with high NUMA balancing activity and then
further pinpoint a specific task within that group, and subsequently
adjust the memory policy for that task. In short, although it is
possible to iterate through /proc/$pid/sched to locate the problematic
task, the introduction of aggregated NUMA balancing activity for tasks
within each memcg can assist users in identifying the task more
efficiently through a divide-and-conquer approach.
As Libo Chen pointed out, the memcg event relies on the text names in
vmstat_text, and /proc/vmstat generates corresponding items based on
vmstat_text. Thus, the relevant task migration and swapping events
introduced in vmstat_text also need to be populated by
count_vm_numa_event(), otherwise these values are zero in /proc/vmstat.
In theory, task migration and swap events are part of the scheduler's
activities. The reason for exposing them through the
memory.stat/vmstat interface is that we already have NUMA balancing
statistics in memory.stat/vmstat, and these events are closely related
to each other. Following Shakeel's suggestion, we describe the
end-to-end flow/story of all these events occurring on a timeline for
future reference:
The goal of NUMA balancing is to co-locate a task and its memory pages
on the same NUMA node. There are two strategies: migrate the pages to
the task's node, or migrate the task to the node where its pages
reside.
Suppose a task p1 is running on Node 0, but its pages are located on
Node 1. NUMA page fault statistics for p1 reveal its "page footprint"
across nodes. If NUMA balancing detects that most of p1's pages are on
Node 1:
1.Page Migration Attempt:
The Numa balance first tries to migrate p1's pages to Node 0.
The numa_page_migrate counter increments.
2.Task Migration Strategies:
After the page migration finishes, Numa balance checks every
1 second to see if p1 can be migrated to Node 1.
Case 2.1: Idle CPU Available
If Node 1 has an idle CPU, p1 is directly scheduled there. This
event is logged as numa_task_migrated.
Case 2.2: No Idle CPU (Task Swap)
If all CPUs on Node1 are busy, direct migration could cause CPU
contention or load imbalance. Instead: The Numa balance selects a
candidate task p2 on Node 1 that prefers Node 0 (e.g., due to its own
page footprint). p1 and p2 are swapped. This cross-node swap is
recorded as numa_task_swapped.

mm: add CONFIG_PAGE_BLOCK_ORDER to select page block order
Problem: On large page size configurations (16KiB, 64KiB), the CMA
alignment requirement (CMA_MIN_ALIGNMENT_BYTES) increases considerably,
and this causes the CMA reservations to be larger than necessary. This
means that system will have less available MIGRATE_UNMOVABLE and
MIGRATE_RECLAIMABLE page blocks since MIGRATE_CMA can't fallback to them.
The CMA_MIN_ALIGNMENT_BYTES increases because it depends on MAX_PAGE_ORDER
which depends on ARCH_FORCE_MAX_ORDER. The value of ARCH_FORCE_MAX_ORDER
increases on 16k and 64k kernels.
For example, in ARM, the CMA alignment requirement when:
- CONFIG_ARCH_FORCE_MAX_ORDER default value is used
- CONFIG_TRANSPARENT_HUGEPAGE is set:
PAGE_SIZE | MAX_PAGE_ORDER | pageblock_order | CMA_MIN_ALIGNMENT_BYTES
-----------------------------------------------------------------------
4KiB | 10 | 9 | 4KiB * (2 ^ 9) = 2MiB
16Kib | 11 | 11 | 16KiB * (2 ^ 11) = 32MiB
64KiB | 13 | 13 | 64KiB * (2 ^ 13) = 512MiB
There are some extreme cases for the CMA alignment requirement when:
- CONFIG_ARCH_FORCE_MAX_ORDER maximum value is set
- CONFIG_TRANSPARENT_HUGEPAGE is NOT set:
- CONFIG_HUGETLB_PAGE is NOT set
PAGE_SIZE | MAX_PAGE_ORDER | pageblock_order | CMA_MIN_ALIGNMENT_BYTES
------------------------------------------------------------------------
4KiB | 15 | 15 | 4KiB * (2 ^ 15) = 128MiB
16Kib | 13 | 13 | 16KiB * (2 ^ 13) = 128MiB
64KiB | 13 | 13 | 64KiB * (2 ^ 13) = 512MiB
This affects the CMA reservations for the drivers. If a driver in a
4KiB kernel needs 4MiB of CMA memory, in a 16KiB kernel, the minimal
reservation has to be 32MiB due to the alignment requirements:
reserved-memory {
...
cma_test_reserve: cma_test_reserve {
compatible = "shared-dma-pool";
size = <0x0 0x400000>; /* 4 MiB */
...
};
};
reserved-memory {
...
cma_test_reserve: cma_test_reserve {
compatible = "shared-dma-pool";
size = <0x0 0x2000000>; /* 32 MiB */
...
};
};
Solution: Add a new config CONFIG_PAGE_BLOCK_ORDER that allows to set the
page block order in all the architectures. The maximum page block order
will be given by ARCH_FORCE_MAX_ORDER.
By default, CONFIG_PAGE_BLOCK_ORDER will have the same value that
ARCH_FORCE_MAX_ORDER. This will make sure that current kernel
configurations won't be affected by this change. It is a opt-in change.
This patch will allow to have the same CMA alignment requirements for
large page sizes (16KiB, 64KiB) as that in 4kb kernels by setting a lower
pageblock_order.
Tests:
- Verified that HugeTLB pages work when pageblock_order is 1, 7, 10 on
4k and 16k kernels.
- Verified that Transparent Huge Pages work when pageblock_order is 1,
7, 10 on 4k and 16k kernels.
- Verified that dma-buf heaps allocations work when pageblock_order is
1, 7, 10 on 4k and 16k kernels.
Benchmarks:
The benchmarks compare 16kb kernels with pageblock_order 10 and 7. The
reason for the pageblock_order 7 is because this value makes the min CMA
alignment requirement the same as that in 4kb kernels (2MB).
- Perform 100K dma-buf heaps (/dev/dma_heap/system) allocations of
SZ_8M, SZ_4M, SZ_2M, SZ_1M, SZ_64, SZ_8, SZ_4. Use simpleperf
(https://developer.android.com/ndk/guides/simpleperf) to measure the #
of instructions and page-faults on 16k kernels. The benchmark was
executed 10 times. The averages are below:
# instructions | #page-faults

There were 4.85% #instructions when order was 7, in comparison with order
10.
13,803,137,433 - 13,131,974,268 = -671,163,166 (-4.86%)
The number of page faults in order 7 and 10 were the same.
These results didn't show any significant regression when the
pageblock_order is set to 7 on 16kb kernels.
