drm/i915/psr: Move pr_dpcd and psr_dpcd to intel_connector
As a preparation for MST Panel Replay we need to move Panel Replay sink
related data into intel_connector. Move pr_dpcd as well into
intel_connector. Generally this is more correct place for this data so move
psr_dpcd as well.
v2:
- move pr/psr_dpcd into *_caps substruct
- drop intel_dp from psr2_su_region_et_valid and
_panel_replay_compute_su_granularity parameters

drm/i915/psr: Use SU granularity information available in intel_connector
Currently we are storing only one set of granularity information for panels supporting both PSR and Panel Replay. As panel is informing own granularities for PSR and Panel Replay they could be different. Let's use own granularities for PSR and Panel Replay instead of having only one set for both. This is done by having intel_connector::psr_caps and panel_replay_caps both containing granularity information. Also remove complexity of sharing granularity read between PSR and Panel Replay. v3: - use cpu_to_le16 for default value v2: - use __le16 for two byte values in dpcd - use sizeof instead of hardcoded size in reading dpcd - drop unnecessarily passing intel_dp pointer Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Link: https://patch.msgid.link/20251204104733.1106145-3-jouni.hogander@intel.com |

i2c: spacemit: fix detect issue
This commit addresses two issues causing i2c detect to fail.
The identified issues are:
1. Incorrect error handling for BED (Bus Error No ACK/NAK):
Before this commit, Both ALD (Arbitration Loss Detected) and
BED returned -EAGAIN.
2. Missing interrupt status clear after initialization in xfer():
On the K1 SoC, simply fixing the first issue changed the error
from -EAGAIN to -ETIMEOUT. Through tracing, it was determined that
this is likely due to MSD (Master Stop Detected) latency issues.
That means the MSD bit in the ISR may still be set on the next transfer.
As a result, the controller won't work — we can see from the scope that
it doesn't issue any signal.
(This only occurs during rapid consecutive I2C transfers.
That explains why the issue only shows up with i2cdetect.)
With these two fixes, i2c device detection now functions correctly on the K1 SoC.

i2c: amd-mp2: fix reference leak in MP2 PCI device
In i2c_amd_probe(), amd_mp2_find_device() utilizes
driver_find_next_device() which internally calls driver_find_device()
to locate the matching device. driver_find_device() increments the
reference count of the found device by calling get_device(), but
amd_mp2_find_device() fails to call put_device() to decrement the
reference count before returning. This results in a reference count
leak of the PCI device each time i2c_amd_probe() is executed, which
may prevent the device from being properly released and cause a memory
leak.
Found by code review.

hwmon: (emc2305) fix device node refcount leak in error path
The for_each_child_of_node() macro automatically manages device node reference counts during normal iteration. However, when breaking out of the loop early with return, the current iteration's node is not automatically released, leading to a reference count leak. Fix this by adding of_node_put(child) before returning from the loop when emc2305_set_single_tz() fails. This issue could lead to memory leaks over multiple probe cycles.

hwmon: (w83791d) Convert macros to functions to avoid TOCTOU
The macro FAN_FROM_REG evaluates its arguments multiple times. When used
in lockless contexts involving shared driver data, this leads to
Time-of-Check to Time-of-Use (TOCTOU) race conditions, potentially
causing divide-by-zero errors.
Convert the macro to a static function. This guarantees that arguments
are evaluated only once (pass-by-value), preventing the race
conditions.
Additionally, in store_fan_div, move the calculation of the minimum
limit inside the update lock. This ensures that the read-modify-write
sequence operates on consistent data.
Adhere to the principle of minimal changes by only converting macros
that evaluate arguments multiple times and are used in lockless
contexts.

mm/slab: introduce kvfree_rcu_barrier_on_cache() for cache destruction
Currently, kvfree_rcu_barrier() flushes RCU sheaves across all slab
caches when a cache is destroyed. This is unnecessary; only the RCU
sheaves belonging to the cache being destroyed need to be flushed.
As suggested by Vlastimil Babka, introduce a weaker form of
kvfree_rcu_barrier() that operates on a specific slab cache.
Factor out flush_rcu_sheaves_on_cache() from flush_all_rcu_sheaves() and
call it from flush_all_rcu_sheaves() and kvfree_rcu_barrier_on_cache().
Call kvfree_rcu_barrier_on_cache() instead of kvfree_rcu_barrier() on
cache destruction.
The performance benefit is evaluated on a 12 core 24 threads AMD Ryzen
5900X machine (1 socket), by loading slub_kunit module.
Before:
Total calls: 19
Average latency (us): 18127
Total time (us): 344414
After:
Total calls: 19
Average latency (us): 10066
Total time (us): 191264
Two performance regression have been reported:
- stress module loader test's runtime increases by 50-60% (Daniel)
- internal graphics test's runtime on Tegra234 increases by 35% (Jon)
They are fixed by this change.

s390/pci: Migrate s390 IRQ logic to IRQ domain API
s390 is one of the last architectures using the legacy API for setup and teardown of PCI MSI IRQs. Migrate the s390 IRQ allocation and teardown to the MSI parent domain API. For details, see: https://lore.kernel.org/lkml/20221111120501.026511281@linutronix.de In detail, create an MSI parent domain for each PCI domain. When a PCI device sets up MSI or MSI-X IRQs, the library creates a per-device IRQ domain for this device, which is used by the device for allocating and freeing IRQs. The per-device domain delegates this allocation and freeing to the parent-domain. In the end, the corresponding callbacks of the parent domain are responsible for allocating and freeing the IRQs. The allocation is split into two parts: - zpci_msi_prepare() is called once for each device and allocates the required resources. On s390, each PCI function has its own airq vector and a summary bit, which must be configured once per function. This is done in prepare(). - zpci_msi_alloc() can be called multiple times for allocating one or more MSI/MSI-X IRQs. This creates a mapping between the virtual IRQ number in the kernel and the hardware IRQ number. Freeing is split into two counterparts: - zpci_msi_free() reverts the effects of zpci_msi_alloc() and - zpci_msi_teardown() reverts the effects of zpci_msi_prepare(). This is called once when all IRQs are freed before a device is removed. Since the parent domain in the end allocates the IRQs, the hwirq encoding must be unambiguous for all IRQs of all devices. This is achieved by encoding the hwirq using the devfn and the MSI index.

genirq: Change hwirq parameter to irq_hw_number_t
The irqdomain implementation internally represents hardware IRQs as irq_hw_number_t, which is defined as unsigned long int. When providing an irq_hw_number_t to the generic_handle_domain() functions that expect and unsigned int hwirq, this can lead to a loss of information. Change the hwirq parameter to irq_hw_number_t to support the full range of hwirqs.

s390: Unmap early KASAN shadow on memory offlining
Teach the memory hotplug path to tear down KASAN shadow that was mapped during early boot when a memory block is offlined. Track for each sclp_mem whether its range was covered by the early KASAN shadow via an early_shadow_mapped flag. When such a block is deconfigured and removed via sclp_config_mem_store(), compute the corresponding shadow range and call vmemmap_free() to unmap the boot mapped shadow, then clear the flag. Using vmemmap_free() for the early shadow is safe despite the use of large mappings in the boot-time KASAN setup. The initial shadow is mapped with 1M and 2G pages, where possible. The minimum hotplug memory block size is 128M and always aligned (the identity mapping is at least 2G aligned), which corresponds to a 16M chunk of at least 1M aligned shadow. PMD-mapped 1M shadow pages therefore never need splitting, and PUD-mapped 2G shadow pages can now be split following the preceding changes. Relax the modify_pagetable() sanity check in vmem so that, with KASAN enabled, it may also operate on the KASAN shadow region in addition to the 1:1 mapping and vmemmap area. This allows the KASAN shadow unmapping to reuse the common vmem helpers.

s390/vmem: Support 2G page splitting for KASAN shadow freeing
Export split_pud_page() so it can be used from the vmem code and teach modify_pud_table() to split PUD-sized mappings when only a subrange needs to be removed. If the range to be removed covers a full PUD-sized mapping, keep the existing behavior: clear the PUD entry and free the backing large page (for non-direct mappings). Otherwise, split the PUD-mapped page into PMD mappings and let the walker handle the smaller ranges. This is needed for KASAN early shadow removal support: memory hotplug freeing the KASAN early shadow is the only expected caller that will try to free 2G PUD-mapped regions of non-direct mappings.

[GIT PULL] perf tools changes for v6.19
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

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]

[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.
[1] https://git.kernel.org/torvalds/c/c69993ecdd4dfde2b7da08b022052a33b203da07
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!

dynamic system of ids
- coresight driver updates
- mwave driver updates
- binder driver updates and changes

Significant patch series in this pull request:
- The 6 patch series "panic: sys_info: Refactor and fix a potential
issue" from Andy Shevchenko fixes a build issue and does some cleanup in
ib/sys_info.c.
- The 9 patch series "Implement mul_u64_u64_div_u64_roundup()" from
David Laight enhances the 64-bit math code on behalf of a PWM driver and
beefs up the test module for these library functions.
- The 2 patch series "scripts/gdb/symbols: make BPF debug info available
to GDB" from Ilya Leoshkevich makes BPF symbol names, sizes, and line
numbers available to the GDB debugger.
- The 4 patch series "Enable hung_task and lockup cases to dump system
info on demand" from Feng Tang adds a sysctl which can be used to cause
additional info dumping when the hung-task and lockup detectors fire.
- The 6 patch series "lib/base64: add generic encoder/decoder, migrate
users" from Kuan-Wei Chiu adds a general base64 encoder/decoder to lib/
and migrates several users away from their private implementations.
- The 2 patch series "rbree: inline rb_first() and rb_last()" from Eric
Dumazet makes TCP a little faster.
- The 9 patch series "liveupdate: Rework KHO for in-kernel users" from
Pasha Tatashin reworks the KEXEC Handover interfaces in preparation for
Live Update Orchestrator (LUO), and possibly for other future clients.
- The 13 patch series "kho: simplify state machine and enable dynamic
updates" from Pasha Tatashin increases the flexibility of KEXEC
Handover. Also preparation for LUO.
- 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.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.
- The 2 patch series "kho: fixes for vmalloc restoration" from Mike
Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.

tracing fixes for v6.19:
- 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. - Fix a bunch of typos -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaTRsYBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qrYpAQC3Qc5QMOlPjqGHXls/4IR4SBEAvsUi VZx3PdknfYCe3AD9HoYGOtrDDhSJ1tQbsWP5ud2jatHwL0zGAl3legNp7ww= =jlNP -----END PGP SIGNATURE----- Merge tag 'trace-v6.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - 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.

Two fixes related to recent introduction of scoped_seqlock_read():
- Fix compiler build failures when a particular .config and
compiler build options variant doesn't result in the
expected removal of unused, catch-bugs portions of
scoped_seqlock_read() by the inliner at build time,
and cause a linker fail even in correct code.
- Match read-locking order in do_task_stat() and
do_io_accounting(). The inconsistency here was harmless
but unnecessary.
