net: phy: smsc: replace deprecated strncpy with ethtool_sprintf
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. ethtool_sprintf() is designed specifically for get_strings() usage. Let's replace strncpy in favor of this dedicated helper function.

bitmap: move bitmap_*_region() functions to bitmap.h
Now that bitmap_*_region() functions are implemented as thin wrappers around others, it's worth to move them to the header, as it opens room for compile-time optimizations.

net: netcp: replace deprecated strncpy with strscpy
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. Other implementations of .*get_drvinfo also use strscpy so this patch brings keystone_get_drvinfo() in line as well: igb/igb_ethtool.c +851 static void igb_get_drvinfo(struct net_device *netdev, igbvf/ethtool.c 167:static void igbvf_get_drvinfo(struct net_device *netdev, i40e/i40e_ethtool.c 1999:static void i40e_get_drvinfo(struct net_device *netdev, e1000/e1000_ethtool.c 529:static void e1000_get_drvinfo(struct net_device *netdev, ixgbevf/ethtool.c 211:static void ixgbevf_get_drvinfo(struct net_device *netdev, Link: https://www.kernel.org/doc/html/latest/process/deprecated.html#strncpy-on-nul-terminated-strings [1] Link: https://manpages.debian.org/testing/linux-manual-4.8/strscpy.9.en.html [2] Link: https://github.com/KSPP/linux/issues/90 Signed-off-by: Justin Stitt <justinstitt@google.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Link: https://lore.kernel.org/r/20231012-strncpy-drivers-net-ethernet-ti-netcp_ethss-c-v1-1-93142e620864@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

smp,csd: Throw an error if a CSD lock is stuck for too long
The CSD lock seems to get stuck in 2 "modes". When it gets stuck temporarily, it usually gets released in a few seconds, and sometimes up to one or two minutes. If the CSD lock stays stuck for more than several minutes, it never seems to get unstuck, and gradually more and more things in the system end up also getting stuck. In the latter case, we should just give up, so the system can dump out a little more information about what went wrong, and, with panic_on_oops and a kdump kernel loaded, dump a whole bunch more information about what might have gone wrong. In addition, there is an smp.panic_on_ipistall kernel boot parameter that by default retains the old behavior, but when set enables the panic after the CSD lock has been stuck for more than the specified number of milliseconds, as in 300,000 for five minutes.

mm/ksm: add "smart" page scanning mode
Patch series "Smart scanning mode for KSM", v3. This patch series adds "smart scanning" for KSM. What is smart scanning? ======================= KSM evaluates all the candidate pages for each scan. It does not use historic information from previous scans. This has the effect that candidate pages that couldn't be used for KSM de-duplication continue to be evaluated for each scan. The idea of "smart scanning" is to keep historic information. With the historic information we can temporarily skip the candidate page for one or several scans. Details: ======== "Smart scanning" is to keep two small counters to store if the page has been used for KSM. One counter stores how often we already tried to use the page for KSM and the other counter stores how often we skip a page. How often we skip the candidate page depends how often a page failed KSM de-duplication. The code skips a maximum of 8 times. During testing this has shown to be a good compromise for different workloads. New sysfs knob: =============== Smart scanning is not enabled by default. With /sys/kernel/mm/ksm/smart_scan smart scanning can be enabled. Monitoring: =========== To monitor how effective smart scanning is a new sysfs knob has been introduced. /sys/kernel/mm/pages_skipped report how many pages have been skipped by smart scanning. Results: ======== - Various workloads have shown a 20% - 25% reduction in page scans For the instagram workload for instance, the number of pages scanned has been reduced from over 20M pages per scan to less than 15M pages. - Less pages scans also resulted in an overall higher de-duplication rate as some shorter lived pages could be de-duplicated additionally - Less pages scanned allows to reduce the pages_to_scan parameter and this resulted in a 25% reduction in terms of CPU. - The improvements have been observed for workloads that enable KSM with madvise as well as prctl This patch (of 4): This change adds a "smart" page scanning mode for KSM. So far all the candidate pages are continuously scanned to find candidates for de-duplication. There are a considerably number of pages that cannot be de-duplicated. This is costly in terms of CPU. By using smart scanning considerable CPU savings can be achieved. This change takes the history of scanning pages into account and skips the page scanning of certain pages for a while if de-deduplication for this page has not been successful in the past. To do this it introduces two new fields in the ksm_rmap_item structure: age and remaining_skips. age, is the KSM age and remaining_skips determines how often scanning of this page is skipped. The age field is incremented each time the page is scanned and the page cannot be de- duplicated. age updated is capped at U8_MAX. How often a page is skipped is dependent how often de-duplication has been tried so far and the number of skips is currently limited to 8. This value has shown to be effective with different workloads. The feature is currently disable by default and can be enabled with the new smart_scan knob. The feature has shown to be very effective: upt to 25% of the page scans can be eliminated; the pages_to_scan rate can be reduced by 40 - 50% and a similar de-duplication rate can be maintained.

dax, kmem: calculate abstract distance with general interface
Previously, a fixed abstract distance MEMTIER_DEFAULT_DAX_ADISTANCE is used for slow memory type in kmem driver. This limits the usage of kmem driver, for example, it cannot be used for HBM (high bandwidth memory). So, we use the general abstract distance calculation mechanism in kmem drivers to get more accurate abstract distance on systems with proper support. The original MEMTIER_DEFAULT_DAX_ADISTANCE is used as fallback only. Now, multiple memory types may be managed by kmem. These memory types are put into the "kmem_memory_types" list and protected by kmem_memory_type_lock.

acpi, hmat: calculate abstract distance with HMAT
A memory tiering abstract distance calculation algorithm based on ACPI HMAT is implemented. The basic idea is as follows. The performance attributes of system default DRAM nodes are recorded as the base line. Whose abstract distance is MEMTIER_ADISTANCE_DRAM. Then, the ratio of the abstract distance of a memory node (target) to MEMTIER_ADISTANCE_DRAM is scaled based on the ratio of the performance attributes of the node to that of the default DRAM nodes. The functions to record the read/write latency/bandwidth of the default DRAM nodes and calculate abstract distance according to read/write latency/bandwidth ratio will be used by CXL CDAT (Coherent Device Attribute Table) and other memory device drivers. So, they are put in memory-tiers.c.

acpi, hmat: refactor hmat_register_target_initiators()
Previously, in hmat_register_target_initiators(), the performance attributes are calculated and the corresponding sysfs links and files are created too. Which is called during memory onlining. But now, to calculate the abstract distance of a memory target before memory onlining, we need to calculate the performance attributes for a memory target without creating sysfs links and files. To do that, hmat_register_target_initiators() is refactored to make it possible to calculate performance attributes separately.

memory tiering: add abstract distance calculation algorithms management
Patch series "memory tiering: calculate abstract distance based on ACPI HMAT", v4. We have the explicit memory tiers framework to manage systems with multiple types of memory, e.g., DRAM in DIMM slots and CXL memory devices. Where, same kind of memory devices will be grouped into memory types, then put into memory tiers. To describe the performance of a memory type, abstract distance is defined. Which is in direct proportion to the memory latency and inversely proportional to the memory bandwidth. To keep the code as simple as possible, fixed abstract distance is used in dax/kmem to describe slow memory such as Optane DCPMM. To support more memory types, in this series, we added the abstract distance calculation algorithm management mechanism, provided a algorithm implementation based on ACPI HMAT, and used the general abstract distance calculation interface in dax/kmem driver. So, dax/kmem can support HBM (high bandwidth memory) in addition to the original Optane DCPMM. This patch (of 4): The abstract distance may be calculated by various drivers, such as ACPI HMAT, CXL CDAT, etc. While it may be used by various code which hot-add memory node, such as dax/kmem etc. To decouple the algorithm users and the providers, the abstract distance calculation algorithms management mechanism is implemented in this patch. It provides interface for the providers to register the implementation, and interface for the users. Multiple algorithm implementations can cooperate via calculating abstract distance for different memory nodes. The preference of algorithm implementations can be specified via priority (notifier_block.priority).

mm/filemap: remove hugetlb special casing in filemap.c
Remove special cased hugetlb handling code within the page cache by
changing the granularity of ->index to the base page size rather than the
huge page size. The motivation of this patch is to reduce complexity
within the filemap code while also increasing performance by removing
branches that are evaluated on every page cache lookup.
To support the change in index, new wrappers for hugetlb page cache
interactions are added. These wrappers perform the conversion to a linear
index which is now expected by the page cache for huge pages.
========================= PERFORMANCE ======================================
Perf was used to check the performance differences after the patch.
Overall the performance is similar to mainline with a very small larger
overhead that occurs in __filemap_add_folio() and
hugetlb_add_to_page_cache(). This is because of the larger overhead that
occurs in xa_load() and xa_store() as the xarray is now using more entries
to store hugetlb folios in the page cache.

A process can enable KSM with the prctl system call. When the process is
forked the KSM flag is inherited by the child process. However if the
process is executing an exec system call directly after the fork, the KSM
setting is cleared. This patch series addresses this problem.
1) Change the mask in coredump.h for execing a new process
2) Add a new test case in ksm_functional_tests
This patch (of 2):
Today we have two ways to enable KSM:
1) madvise system call
This allows to enable KSM for a memory region for a long time.
2) prctl system call
This is a recent addition to enable KSM for the complete process.
In addition when a process is forked, the KSM setting is inherited.
This change only affects the second case.
One of the use cases for (2) was to support the ability to enable
KSM for cgroups. This allows systemd to enable KSM for the seed
process. By enabling it in the seed process all child processes inherit
the setting.
This works correctly when the process is forked. However it doesn't
support fork/exec workflow.
From the previous cover letter:
....
Use case 3:
With the madvise call sharing opportunities are only enabled for the
current process: it is a workload-local decision. A considerable number
of sharing opportunities may exist across multiple workloads or jobs
(if they are part of the same security domain). Only a higler level
entity like a job scheduler or container can know for certain if its
running one or more instances of a job. That job scheduler however
doesn't have the necessary internal workload knowledge to make targeted
madvise calls.
....
In addition it can also be a bit surprising that fork keeps the KSM
setting and fork/exec does not.

mm: memory: add vm_normal_folio_pmd()
Patch series "mm: convert numa balancing functions to use a folio", v2. do_numa_pages() only handles non-compound pages, and only PMD-mapped THPs are handled in do_huge_pmd_numa_page(). But a large, PTE-mapped folio will be supported so let's convert more numa balancing functions to use/take a folio in preparation for that, no functional change intended for now. This patch (of 6): The new vm_normal_folio_pmd() wrapper is similar to vm_normal_folio(), which allow them to completely replace the struct page variables with struct folio variables.

Arm FF-A updates for v6.7
The main addition is the initial support for the notifications and memory transaction descriptor changes added in FF-A v1.1 specification. The notification mechanism enables a requester/sender endpoint to notify a service provider/receiver endpoint about an event with non-blocking semantics. A notification is akin to the doorbell between two endpoints in a communication protocol that is based upon the doorbell/mailbox mechanism. The framework is responsible for the delivery of the notification from the ender to the receiver without blocking the sender. The receiver endpoint relies on the OS scheduler for allocation of CPU cycles to handle a notification. OS is referred as the receiver’s scheduler in the context of notifications. The framework is responsible for informing the receiver’s scheduler that the receiver must be run since it has a pending notification.

The notification mechanism enables a requester/sender endpoint to notify a service provider/receiver endpoint about an event with non-blocking semantics. A notification is akin to the doorbell between two endpoints in a communication protocol that is based upon the doorbell/mailbox mechanism. The framework is responsible for the delivery of the notification from the ender to the receiver without blocking the sender. The receiver endpoint relies on the OS scheduler for allocation of CPU cycles to handle a notification. OS is referred as the receiver’s scheduler in the context of notifications. The framework is responsible for informing the receiver’s scheduler that the receiver must be run since it has a pending notification. The series also includes support for the new format of memory transaction descriptors introduced in v1.1 specification. Apart from the main additions, it includes minor fixes to re-enable FF-A drivers usage of 32bit mode of messaging and kernel warning due to the missing assignment of IDR allocation ID to the FFA device.

Arm SCMI updates for v6.7
Main additions this time include:
1. SCMI v3.2 clock configuration support:
This helps to retrieve the enabled state of a clock as well as allow
to set OEM specific clock configurations.
2. Support for generic performance scaling(DVFS):
The current SCMI DVFS support is limited to the CPUs in the kernel.
This extension enables it to used for all kind of devices and not
only for the CPUs. It updates the SCMI cpufreq to utilize the power
domain bindings. It also adds a more generic SCMI performance domain
based on the genpd framework that as be used for all the non-CPU
devices.
3. Extend the generic performance scaling(DVFS) support for firmware
driver OPPs:
Consumer drivers for devices that are attached to the SCMI performance
domain can't make use of the current OPP library to scale performance
as the OPPs are firmware driven and often obtained from the firmware
rather than the device tree. These changes extend the generic OPP
and genpd PM domain frameworks to identify and utilise these firmware
driven OPPs.
4. SCMI v3.2 clock parent support:
This enables the support for discovering and changing parent clocks
and extending the SCMI clk driver to use the same.
5. Qualcom SMC/HVC transport support:
The Qualcomm virtual platforms require capability id in the hypervisor
call to identify which doorbell to assert when supporting multiple
SMC/HVC based SCMI transport channels. Extra parameter is added to
support the same and the same is obtained at the fixed address in the
shared memory which is initialised by the firmware.
6. Move the existing SCMI power domain driver under drivers/pmdomain
Apart from the above main changes, it also include couple of minor fixes
and cosmetic reworks.

It converts all drivers below drivers/soc to let their remove callback return void. See commit |

soc: samsung: exynos-chipid: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

dt-bindings: panel: Add Powkiddy RGB30 panel compatible
The Powkiddy RGB30 panel is a 4 inch 720x720 MIPI-DSI LCD panel. It appears to be based on the ST7703 LCD controller (this is assumed from the init sequence similarity between this and other displays). Powkiddy would not share the part number or name for the display from the bill of materials and there were no obvious external markings, so name the panel for the device (Powkiddy RGB30).
