* [PATCH v10 07/20] coresight: Register CPU PM notifier in core layer

In-Reply-To: <20260405-arm_coresight_path_power_management_improvement-v10-0-13e94754a8be@arm.com>

The current implementation only saves and restores the context for ETM
sources while ignoring the context of links.  However, if funnels or
replicators on a linked path resides in a CPU or cluster power domain,
the hardware context for the link will be lost after resuming from low
power states.

To support context management for links during CPU low power modes, a
better way is to implement CPU PM callbacks in the Arm CoreSight core
layer.  As the core layer has sufficient information for linked paths,
from tracers to links, which can be used for power management.

As a first step, this patch registers CPU PM notifier in the core layer.
If a source device provides callbacks for saving and restoring context,
these callbacks will be invoked in CPU suspend and resume.

* [PATCH v10 04/20] coresight: Take hotplug lock in enable_source_store() for Sysfs mode
From: Leo Yan @ 2026-04-05 15:02 UTC (permalink / raw)
  To: Suzuki K Poulose, Mike Leach, James Clark, Yeoreum Yun,
	Mark Rutland, Will Deacon, Yabin Cui, Keita Morisaki,

  Cc: coresight, linux-arm-kernel, Leo Yan, Mike Leach
In-Reply-To: <20260405-arm_coresight_path_power_management_improvement-v10-0-13e94754a8be@arm.com>

The hotplug lock is acquired and released in etm{3|4}_disable_sysfs(),
which are low-level functions.  This prevents us from a new solution for
hotplug.

Firstly, hotplug callbacks cannot invoke etm{3|4}_disable_sysfs() to
disable the source; otherwise, a deadlock issue occurs.  The reason is
that, in the hotplug flow, the kernel acquires the hotplug lock before
calling callbacks.  Subsequently, if coresight_disable_source() is
invoked and it calls etm{3|4}_disable_sysfs(), the hotplug lock will be
acquired twice, leading to a double lock issue.

Secondly, when hotplugging a CPU on or off, if we want to manipulate all
components on a path attached to the CPU, we need to maintain atomicity
for the entire path.  Otherwise, a race condition may occur with users
setting the same path via the Sysfs knobs, ultimately causing mess
states in CoreSight components.

This patch moves the hotplug locking from etm{3|4}_disable_sysfs() into
enable_source_store().  As a result, when users control the Sysfs knobs,
the whole flow is protected by hotplug locking, ensuring it is mutual
exclusive with hotplug callbacks.

Note, the paired function etm{3|4}_enable_sysfs() does not use hotplug
locking, which is why this patch does not modify it.

In-Reply-To: <20260405-arm_coresight_path_power_management_improvement-v10-0-13e94754a8be@arm.com>

The CPU ID can be fetched directly from the coresight_device structure,
so the .cpu_id() callback is no longer needed.

Remove the .cpu_id() callback from source ops and update callers
accordingly.

* [PATCH v10 02/20] coresight: Populate CPU ID into coresight_device

In-Reply-To: <20260405-arm_coresight_path_power_management_improvement-v10-0-13e94754a8be@arm.com>

Add a new flag CORESIGHT_DESC_CPU_BOUND to indicate components that
are CPU bound.  Populate CPU ID into the coresight_device structure;
otherwise, set CPU ID to -1 for non CPU bound devices.

Use the {0} initializer to clear coresight_desc structures to avoid
uninitialized values.

* [PATCH v10 00/20] CoreSight: Refactor power management for CoreSight path
From: Leo Yan @ 2026-04-05 15:02 UTC (permalink / raw)
  To: Suzuki K Poulose, Mike Leach, James Clark, Yeoreum Yun,
	Mark Rutland, Will Deacon, Yabin Cui, Keita Morisaki,

	Tamas Petz, Thomas Gleixner, Peter Zijlstra
  Cc: coresight, linux-arm-kernel, Leo Yan, Mike Leach

This series focuses on CoreSight path power management.  The changes can
be divided into four parts for review:

  Patches 01 - 04: Refactor the CPU ID storing in csdev, later patches
                   consume csdev->cpu.  Move CPU lock to sysfs layer so
		   it is safe for later changes.
  Patches 05 - 09: Refactor the CPU idle flow with moving common code into
                   the CoreSight core layer.
  Patches 10 - 15: Refactor path enabling and disabling with range, add
                   path control during CPU idle.
  Patches 16 - 17: Support the sink (TRBE) control during CPU idle.
  Patches 18 - 20: Move CPU hotplug into the core layer, and fix sysfs
                   mode for hotplug.

This series is rebased on the coresight-next branch and has been verified
on Juno-r2 (ETM + ETR) and FVP RevC (ETE + TRBE).  Built successfully
for armv7 (ARCH=arm).

---
Changes in v10:
- Removed redundant checks in ETMv4 PM callbacks (sashiko).
- Added a new const structure etm4_cs_pm_ops (sashiko).
- Used fine-grained spinlock on sysfs_active_config (sashiko).
- Blocked notification after failures in save / restore to avoid lockups.
- Changed Change CPUHP_AP_ARM_CORESIGHT_STARTING to
  CPUHP_AP_ARM_CORESIGHT_ONLINE so that the CPU hotplug callback runs in
  the thread context (sashiko).
- Link to v9: https://lore.kernel.org/r/20260401-arm_coresight_path_power_management_improvement-v9-0-091d73e44072@arm.com

Changes in v9:
- Changed to use per-CPU path pointer with lockless access.
- Removed the change for adding csdev->path, the related refactoring
  will be sent separately.
- Re-orged patches to avoid intermediate breakage (sashiko).
- Link to v8: https://lore.kernel.org/r/20260325-arm_coresight_path_power_management_improvement-v8-0-7b1902e18041@arm.com

Changes in v8:
- Moved the "cpu" field in coresight_device for better pack with new
  patch 01 (Suzuki).
- Added check if not set CPU for per_cpu_source/per_cpu_sink (Suzuki).
- Renamed spinlock name in syscfg (Suzuki).
- Refactored paired enable and disable path with new patches
  10 and 12 (Suzuki).
- Link to v7: https://lore.kernel.org/r/20260320-arm_coresight_path_power_management_improvement-v7-0-327ddd36b58b@arm.com

Changes in v7:
- Added a flag in coresight_desc to indicate CPU bound device (Suzuki).
- Used coresight_mutex to protect per-CPU source pointer (Suzuki).
- Added a spinlock for exclusive access per-CPU source pointer (Suzuki).
- Dropped .pm_is_needed() callback (Suzuki).
- Supported range in path enabling / disabling (Suzuki).
- Gathered test and review tags (Levi / James).

* [PATCH] gpio: aspeed: fix unsigned long int declaration
From: Chen Jung Ku @ 2026-04-05 14:48 UTC (permalink / raw)
  To: linusw, brgl, joel, andrew
  Cc: linux-gpio, linux-arm-kernel, linux-aspeed, linux-kernel,

Replace "unsigned long int" with "unsigned long"
to follow Linux kernel coding style.
No functional change intended.

* [PATCH] arm64: kexec: Remove duplicate allocation for trans_pgd
From: Wang Wensheng @ 2026-04-05 11:42 UTC (permalink / raw)
  To: catalin.marinas, will, mrigendra.chaubey, pasha.tatashin,
	linux-arm-kernel, linux-kernel
  Cc: wsw9603

trans_pgd would be allocated in trans_pgd_create_copy(), so remove the
duplicate allocation before calling trans_pgd_create_copy().

* [PATCH] i2c: p2wi: use dev_err_probe() for clock and reset errors
From: Adeel Zahid @ 2026-04-05  3:40 UTC (permalink / raw)
  To: Andi Shyti, Chen-Yu Tsai, Jernej Skrabec, Samuel Holland
  Cc: linux-i2c, linux-arm-kernel, linux-sunxi, Adeel Zahid

Replace open-coded error logging and returns with dev_err_probe() when acquiring the clock and reset controller in probe.

This makes the error handling more concise and correctly handles deferred probe.

* Re: [PATCH] arm64: pi: validate bootargs before parsing them
From: Pengpeng Hou @ 2026-04-05  1:40 UTC (permalink / raw)
  To: Catalin Marinas, Will Deacon; +Cc: linux-arm-kernel, linux-kernel, pengpeng
In-Reply-To: <20260403143004.4-arm64-pi-bootargs-pengpeng@iscas.ac.cn>

Hi Will,

Thanks, that's a fair question.

The reason I cared here is not that we can make every malformed FDT survive
cleanly, but that this particular caller turns a raw property into an
unbounded C string immediately:

  fdt_getprop() -> strlen() -> __parse_cmdline()

If `bootargs` is not NUL-terminated within the property bounds, `strlen()`
can walk past the property before the parser even starts. By contrast, a
NUL-terminated but semantically bogus string stays within the property bounds
and is then just handled as bad/ignored command-line content.

So the issue I was trying to harden is specifically “raw FDT property becomes
a C string without a local bound check”, not malformed DT handling in the
broadest sense.

You're also right to ask about scope. I do not think every early
`fdt_getprop()` caller should be converted mechanically; the ones that matter
here are the callers that immediately feed raw properties into unbounded
string helpers or parsers. This arm64 PI bootargs path is one of those.

I will rework this around that boundary instead of pushing this one caller in
isolation. In other words, I will audit the same early-bootargs family of
callers and only convert the ones that have this direct
`raw property -> unbounded C-string helper/parser` shape.

Thanks,
Pengpeng

* [PATCH v2] ARM: mvebu: validate memory node device_type before strcmp()
From: Pengpeng Hou @ 2026-04-05  0:41 UTC (permalink / raw)
  To: Andrew Lunn, Gregory Clement, Sebastian Hesselbarth
  Cc: linux-arm-kernel, linux-kernel, pengpeng
In-Reply-To: <20260403111504.4-dt-arm-mvebu-pengpeng@iscas.ac.cn>

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 1534 bytes --]

mvebu_scan_mem() fetches the flat-DT device_type property and immediately
compares it with strcmp(). Flat DT properties are external boot input,
and this path does not prove that the property is NUL-terminated within
the returned property length.

Keep the existing flat-DT lookup path, but reject malformed
unterminated device_type values before comparing them as C strings.
This preserves the current distinction between an absent property and a
bad property value.

Changes since v1:
- keep `of_get_flat_dt_prop()` instead of switching to `fdt_stringlist_get()`
- preserve the existing “not found” vs malformed-value behavior

* [PATCH v2] ARM: xen: validate hypervisor compatible before parsing its version
From: Pengpeng Hou @ 2026-04-05  0:42 UTC (permalink / raw)
  To: Stefano Stabellini; +Cc: xen-devel, linux-arm-kernel, linux-kernel, pengpeng
In-Reply-To: <20260403111502.2-dt-arm-xen-pengpeng@iscas.ac.cn>

fdt_find_hyper_node() reads the raw compatible property and then derives
hyper_node.version from a prefix match before later printing it with %s.
Flat DT properties are external boot input, and this path does not prove
that the first compatible entry is NUL-terminated within the returned
property length.

Keep the existing flat-DT lookup path, but verify that the first
compatible entry terminates within the returned property length before
deriving the version suffix from it.

Hi! Joonwon Kang.

I just looked at the content of your email, and I think we can design a resource priority scheduling system with 70% and 30% priority allocation. The specific idea is as follows:

During task execution, each task can be tagged. Important tasks can be allocated to the 30% of resources, while the remaining 70% can be used to run low-load and repetitive pipeline tasks.

The specific algorithm can be written as follows: reserve 30% of the runtime space for the system's critical processes. For the remaining 70% of non-critical processes, a judgment can be made: if resource usage exceeds 70%, the excess processes are marked with a priority deferred tag and run only when resources are freed up.
