Perf event/metric description
-----------------------------
Unify all event and metric descriptions in JSON format.
Now event parsing and handling is greatly simplified by that.
From users point of view, perf list will provide richer
information about hardware events like the following.
$ perf list hw
List of pre-defined events (to be used in -e or -M):
legacy hardware:
branch-instructions
[Retired branch instructions [This event is an alias of branches]. Unit: cpu]
branch-misses
[Mispredicted branch instructions. Unit: cpu]
branches
[Retired branch instructions [This event is an alias of branch-instructions]. Unit: cpu]
bus-cycles
[Bus cycles,which can be different from total cycles. Unit: cpu]
cache-misses
[Cache misses. Usually this indicates Last Level Cache misses; this is intended to be used in conjunction with the
PERF_COUNT_HW_CACHE_REFERENCES event to calculate cache miss rates. Unit: cpu]
cache-references
[Cache accesses. Usually this indicates Last Level Cache accesses but this may vary depending on your CPU. This may include
prefetches and coherency messages; again this depends on the design of your CPU. Unit: cpu]
cpu-cycles
[Total cycles. Be wary of what happens during CPU frequency scaling [This event is an alias of cycles]. Unit: cpu]
cycles
[Total cycles. Be wary of what happens during CPU frequency scaling [This event is an alias of cpu-cycles]. Unit: cpu]
instructions
[Retired instructions. Be careful,these can be affected by various issues,most notably hardware interrupt counts. Unit: cpu]
ref-cycles
[Total cycles; not affected by CPU frequency scaling. Unit: cpu]
But most notable changes would be in the perf stat. On the right side,
the default metrics are better named and aligned. :)

Deferred unwinding support
--------------------------
With the kernel support [1], perf can use deferred callchains for
userspace stack trace with frame pointers like below:
$ perf record --call-graph fp,defer ...
This will be transparent to users when it comes to other commands like
perf report and perf script. They will merge the deferred callchains to
the previous samples as if they were collected together.

ARM SPE updates
---------------
* Extensive enhancements to support various kinds of memory operations
including GCS, MTE allocation tags, memcpy/memset, register access,
and SIMD operations.
* Add inverted data source filter (inv_data_src_filter) support to
exclude certain data sources.
* Improve documentation.
Vendor event updates
--------------------
* Intel: Updated event files for Sierra Forest, Panther Lake, Meteor Lake,
Lunar Lake, Granite Rapids, and others.
* Arm64: Added metrics for i.MX94 DDR PMU and Cortex-A720AE definitions.
* RISC-V: Added JSON support for T-HEAD C920V2.
Misc
----
* Improve pointer tracking in data type profiling. It'd give better
output when the variable is using container_of() to convert type.
* Annotation support for perf c2c report in TUI. Press 'a' key to
enter annotation view from cacheline browser window. This will show
which instruction is causing the cacheline contention.
* Lots of fixes and test coverage improvements!

Deferred unwinding support:
With the kernel support (commit c69993ecdd4d: "perf: Support deferred
user unwind"), perf can use deferred callchains for userspace stack
trace with frame pointers like below:
$ perf record --call-graph fp,defer ...
This will be transparent to users when it comes to other commands like
perf report and perf script. They will merge the deferred callchains
to the previous samples as if they were collected together.
ARM SPE updates
- Extensive enhancements to support various kinds of memory
operations including GCS, MTE allocation tags, memcpy/memset,
register access, and SIMD operations.
- Add inverted data source filter (inv_data_src_filter) support to
exclude certain data sources.
- Improve documentation.
Vendor event updates:
- Intel: Updated event files for Sierra Forest, Panther Lake, Meteor
Lake, Lunar Lake, Granite Rapids, and others.
- Arm64: Added metrics for i.MX94 DDR PMU and Cortex-A720AE
definitions.
- RISC-V: Added JSON support for T-HEAD C920V2.
Misc:
- Improve pointer tracking in data type profiling. It'd give better
output when the variable is using container_of() to convert type.
- Annotation support for perf c2c report in TUI. Press 'a' key to
enter annotation view from cacheline browser window. This will show
which instruction is causing the cacheline contention.
- Lots of fixes and test coverage improvements!"

Here is the big set of staging driver updates for 6.19-rc1. Only thing
"major" in here is that two subsystems, gpib and vc04 have moved out of
the staging tree into the "real" portion of the kernel, which is great
to see. Other than that, the rest of the changes are just tiny coding
style cleanups, nothing earth-shattering.
All of these have been in linux-next for a while with no reported

Commit 2f26f58df0 ("ocfs2: annotate flexible array members with
__counted_by_le()") started annotating the flexible arrays used by
ocfs2, and now gcc complains about ocfs2_reflink_xattr_header():
In function ‘fortify_memset_chk’,
inlined from ‘ocfs2_reflink_xattr_header’ at fs/ocfs2/xattr.c:6365:5:
include/linux/fortify-string.h:480:25: error: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
and it looks like the complaint is valid - even if the actual error
message is somewhat confusing.
The 'last' pointer points to past the end of the counted flex array, but
is used as an actual 'last' entry rather than a 'one-past-last'.
It looks like the code copied and cleared an extra entry (which is
likely harmless in practice), but I don't know ocfs2 at all. Because
it's also possible that the counted-by annotations are off-by-one, and
so this needs checking by somebody who actually knows ocfs2.
But in the meantime this fixes the build error, and certainly _looks_
sane.

- The 18 patch series "Live Update Orchestrator" from Pasha Tatashin is
a major new feature targeted at cloud environments. Quoting the [0/N]:
This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.

- "Live Update Orchestrator" (Pasha Tatashin)
is a major new feature targeted at cloud environments. Quoting the
cover letter:
This series introduces the Live Update Orchestrator, a kernel
subsystem designed to facilitate live kernel updates using a
kexec-based reboot. This capability is critical for cloud
environments, allowing hypervisors to be updated with minimal
downtime for running virtual machines. LUO achieves this by
preserving the state of selected resources, such as memory,
devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving
memfd file descriptors, which allows critical in-memory data, such
as guest RAM or any other large memory region, to be maintained in
RAM across the kexec reboot.

testing work.

- Fix accounting of stop_count in file release
On opening the trace file, if "pause-on-trace" option is set, it will
increment the stop_count. On file release, it checks if stop_count is set,
and if so it decrements it. Since this code was originally written, the
stop_count can be incremented by other use cases. This makes just checking
the stop_count not enough to know if it should be decremented.
Add a new iterator flag called "PAUSE" and have it set if the open
disables tracing and only decrement the stop_count if that flag is set on
close.
- Remove length field in trace_seq_printf() of print_synth_event()
When printing the synthetic event that has a static length array field,
the vsprintf() of the trace_seq_printf() triggered a "(efault)" in the
output. That's because the print_fmt replaced the "%.*s" with "%s" causing
the arguments to be off.

about the config options that expose amd_iommu_sev_tio_supported(), and
made the declaration (and alternative dummy function) conditional on the

But the code is actually dependent on CONFIG_KVM_AMD_SEV, resulting in

Pull PCIe Link Encryption and Device Authentication from Dan Williams:
"New PCI infrastructure and one architecture implementation for PCIe
link encryption establishment via platform firmware services.
This work is the result of multiple vendors coming to consensus on
some core infrastructure (thanks Alexey, Yilun, and Aneesh!), and
three vendor implementations, although only one is included in this
pull. The PCI core changes have an ack from Bjorn, the crypto/ccp/
changes have an ack from Tom, and the iommu/amd/ changes have an ack
from Joerg.
PCIe link encryption is made possible by the soup of acronyms
mentioned in the shortlog below. Link Integrity and Data Encryption
(IDE) is a protocol for installing keys in the transmitter and
receiver at each end of a link. That protocol is transported over Data
Object Exchange (DOE) mailboxes using PCI configuration requests.
The aspect that makes this a "platform firmware service" is that the
key provisioning and protocol is coordinated through a Trusted
Execution Envrionment (TEE) Security Manager (TSM). That is either
firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor
software (Intel TDX Connect / ARM CCA) running in a protected CPU
mode.
Now, the only reason to ask a TSM to run this protocol and install the
keys rather than have a Linux driver do the same is so that later, a
confidential VM can ask the TSM directly "can you certify this
device?".
That precludes host Linux from provisioning its own keys, because host
Linux is outside the trust domain for the VM. It also turns out that
all architectures, save for one, do not publish a mechanism for an OS
to establish keys in the root port. So "TSM-established link
encryption" is the only cross-architecture path for this capability
for the foreseeable future.
This unblocks the other arch implementations to follow in v6.20/v7.0,
once they clear some other dependencies, and it unblocks the next
phase of work to implement the end-to-end flow of confidential device
assignment. The PCIe specification calls this end-to-end flow Trusted
Execution Environment (TEE) Device Interface Security Protocol
(TDISP).
In the meantime, Linux gets a link encryption facility which has
practical benefits along the same lines as memory encryption. It
authenticates devices via certificates and may protect against
interposer attacks trying to capture clear-text PCIe traffic.
Summary:
- Introduce the PCI/TSM core for the coordination of device
authentication, link encryption and establishment (IDE), and later
management of the device security operational states (TDISP).
Notify the new TSM core layer of PCI device arrival and departure
- Add a low level TSM driver for the link encryption establishment
capabilities of the AMD SEV-TIO architecture
- Add a library of helpers TSM drivers to use for IDE establishment
and the DOE transport
- Add skeleton support for 'bind' and 'guest_request' operations in

Commit 14e9a18b07 ("rust: sync: atomic: Make Atomic*Ops pub(crate)")
added a `pub(crate)` import in the same "block" as the `pub` one,
without running `rustfmt`, which would sort them differently.
Instead of running `rustfmt` as-is, add a newline to keep the import
"blocks" with different visibilities separate.

Rust module parameter support:
- Add Rust module parameter support, enabling Rust kernel modules to declare
and use module parameters. The rust_minimal sample module demonstrates this,
and the rust null block driver will be the first to use it in the next cycle.
This also adds the Rust module files under the modules subsystem as agreed
between the Rust and modules maintainers.
Hardening:
- Add compile-time check for embedded NUL characters in MODULE_*() macros. This
module metadata was once used (and maybe still) to bypass license enforcement
(LWN article [1] from 2003). This change required a sparse fix [2] which you
reviewed.
MAINTAINERS:
- Add Aaron Tomlin as reviewer for the Modules subsystem.
The changes have been in linux-next for 4 weeks. Recent 0day reports for UM [3]
and arm64 [4] builds were not reproducible and traced to a buggy bindgen version
combined with unreleased clang-22 in 0day. The Rust team has reported this to
0day.
As discussed previously, we rotate module maintainership among co-maintainers
every 6 months. Sami Tolvanen is next in line and will send the next pull
request. As a reminder, Luis has already announced [5] he will gradually step
away as maintainer.

Currently, if the sleep flag is set, psi_dequeue() doesn't
change any of the psi_flags.
This is because psi_task_switch() will clear TSK_ONCPU as well
as other potential flags (TSK_RUNNING), and the assumption is
that a voluntary sleep always consists of a task being dequeued
followed shortly there after with a psi_sched_switch() call.
Proxy Execution changes this expectation, as mutex-blocked tasks
that would normally sleep stay on the runqueue. But in the case
where the mutex-owning task goes to sleep, or the owner is on a
remote cpu, we will then deactivate the blocked task shortly
after.
In that situation, the mutex-blocked task will have had its
TSK_ONCPU cleared when it was switched off the cpu, but it will
stay TSK_RUNNING. Then if we later dequeue it (as currently done
if we hit a case find_proxy_task() can't yet handle, such as the
case of the owner being on another rq or a sleeping owner)
psi_dequeue() won't change any state (leaving it TSK_RUNNING),
as it incorrectly expects a psi_task_switch() call to
immediately follow.
Later on when the task get woken/re-enqueued, and psi_flags are
set for TSK_RUNNING, we hit an error as the task is already
TSK_RUNNING:
psi: inconsistent task state! task=188:kworker/28:0 cpu=28 psi_flags=4 clear=0 set=4
To resolve this, extend the logic in psi_dequeue() so that
if the sleep flag is set, we also check if psi_flags have
TSK_ONCPU set (meaning the psi_task_switch is imminent) before
we do the shortcut return.
If TSK_ONCPU is not set, that means we've already switched away,
and this psi_dequeue call needs to clear the flags.

When a task is migrated out, there is a probability that the tg->load_avg
value will become abnormal. The reason is as follows:
1. Due to the 1ms update period limitation in update_tg_load_avg(), there
is a possibility that the reduced load_avg is not updated to tg->load_avg
when a task migrates out.
2. Even though __update_blocked_fair() traverses the leaf_cfs_rq_list and
calls update_tg_load_avg() for cfs_rqs that are not fully decayed, the key
function cfs_rq_is_decayed() does not check whether
cfs->tg_load_avg_contrib is null. Consequently, in some cases,
__update_blocked_fair() removes cfs_rqs whose avg.load_avg has not been
updated to tg->load_avg.
Add a check of cfs_rq->tg_load_avg_contrib in cfs_rq_is_decayed(),
which fixes the case (2.) mentioned above.

rt_mutex_setprio() has only one caller: rt_mutex_adjust_prio(). It
expects that task_struct::pi_lock and rt_mutex_base::wait_lock are held.
Both locks are raw_spinlock_t and are acquired with disabled interrupts.
Nevertheless rt_mutex_setprio() disables preemption while invoking
__balance_callbacks() and raw_spin_rq_unlock(). Even if one of the
balance callbacks unlocks the rq then it must not enable interrupts
because rt_mutex_base::wait_lock is still locked.
Therefore interrupts should remain disabled and disabling preemption is
not needed.
Commit 4c9a4bc89a ("sched: Allow balance callbacks for check_class_changed()")
adds a preempt-disable section to rt_mutex_setprio() and
__sched_setscheduler(). In __sched_setscheduler() the preemption is
disabled before rq is unlocked and interrupts enabled but I don't see
why it makes a difference in rt_mutex_setprio().
Remove the preempt_disable() section from rt_mutex_setprio().

The sched_class::task_tick() method is called on the donor
sched_class, and sched_tick() hands it rq->donor as argument,
which is consistent.
However, while hrtick() uses the donor sched_class, it then passes
rq->curr, which is inconsistent. Fix it.

Arnd reported an x86 randconfig using gcc-15 tripped over
__scoped_seqlock_bug(). Turns out GCC chose not to inline the
scoped_seqlock helper functions and as such was not able to optimize
properly.
[ mingo: Clang fails the build too in some circumstances. ]

Commit f2060bdc21 ("nfs/localio: add refcounting for each iocb IO
associated with NFS pgio header") inadvertantly reintroduced the same
potential for __put_cred() triggering BUG_ON(cred == current->cred) that
commit 992203a1fb ("nfs/localio: restore creds before releasing pageio
data") fixed.
Fix this by saving and restoring the cred around each {read,write}_iter
call within the respective for loop of nfs_local_call_{read,write} using
scoped_with_creds().
NOTE: this fix started by first reverting the following commits:
94afb627df ("nfs: use credential guards in nfs_local_call_read()")
bff3c841f7 ("nfs: use credential guards in nfs_local_call_write()")
1d18101a64 ("Merge tag 'kernel-6.19-rc1.cred' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs")
followed by narrowly fixing the cred lifetime issue by using
scoped_with_creds(). In doing so, this commit's changes appear more
extensive than they really are (as evidenced by comparing to v6.18's
fs/nfs/localio.c).

tag than the others:
- A new driver for cache management on cxl devices with memory shared
in a coherent cluster. This is part of the drivers/cache/ tree, but
unlike the other drivers that back the dma-mapping interfaces, this
one is needed only during CPU hotplug.
- A shared branch for reset controllers using swnode infrastructure

power management, as a preparation for future Tegra specific
changes.
- Reset controller updates with added drivers for LAN969x, eic770
and RZ/G3S SoCs.
- Protection of system controller registers on Renesas and Google SoCs,
to prevent trivially triggering a system crash from e.g. debugfs
access.
- soc_device identification updates on Nvidia, Exynos and Mediatek
- debugfs support in the ST STM32 firewall driver
- Minor updates for SoC drivers on AMD/Xilinx, Renesas, Allwinner, TI
- Cleanups for memory controller support on Nvidia and Renesas
