2024-05-01acpi/ghes: Process CXL Component EventsIra Weiny
BIOS can configure memory devices as firmware first. This will send CXL events to the firmware instead of the OS. The firmware can then inform the OS of these events via UEFI. UEFI v2.10 section N.2.14 defines a Common Platform Error Record (CPER) format for CXL Component Events. The format is mostly the same as the CXL Common Event Record Format. The difference lies in the use of a GUID as the CPER Section Type which matches the UUID defined in CXL 3.1 Table 8-43. Currently a configuration such as this will trace a non standard event in the log omitting useful details of the event. In addition the CXL sub-system contains additional region and HPA information useful to the user.[0] The CXL code is required to be called from process context as it needs to take a device lock. The GHES code may be in interrupt context. This complicated the use of a callback. Dan Williams suggested the use of work items as an atomic way of switching between the callback execution and a default handler.[1] The use of a kfifo simplifies queue processing by providing lock free fifo operations. cxl_cper_kfifo_get() allows easier management of the kfifo between the ghes and cxl modules. CXL 3.1 Table 8-127 requires a device to have a queue depth of 1 for each of the four event logs. A combined queue depth of 32 is chosen to provide room for 8 entries of each log type. Add GHES support to detect CXL CPER records. Add the ability for the CXL sub-system to register a work queue to process the events. This patch adds back the functionality which was removed to fix the report by Dan Carpenter[2]. Cc: Ard Biesheuvel <ardb@kernel.org> Cc: Rafael J.

2024-05-01objpool: cache nr_possible_cpus() and avoid caching nr_cpu_idsAndrii Nakryiko
Profiling shows that calling nr_possible_cpus() in objpool_pop() takes a noticeable amount of CPU (when profiled on 80-core machine), as we need to recalculate number of set bits in a CPU bit mask. This number can't change, so there is no point in paying the price for recalculating it. As such, cache this value in struct objpool_head and use it in objpool_pop(). On the other hand, cached pool->nr_cpus isn't necessary, as it's not used in hot path and is also a pretty trivial value to retrieve. So drop pool->nr_cpus in favor of using nr_cpu_ids everywhere. This way the size of struct objpool_head remains the same, which is a nice bonus. Same BPF selftests benchmarks were used to evaluate the effect. Using changes in previous patch (inlining of objpool_pop/objpool_push) as baseline, here are the differences: BASELINE ======== kretprobe : 9.937 ± 0.174M/s kretprobe-multi: 10.440 ± 0.108M/s AFTER ===== kretprobe : 10.106 ± 0.120M/s (+1.7%) kretprobe-multi: 10.515 ± 0.180M/s (+0.7%) Link: https://lore.kernel.org/all/20240424215214.3956041-3-andrii@kernel.org/ Cc: Matt (Qiang) Wu <wuqiang.matt@bytedance.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Masami Hiramatsu (Google) <mhiramat@kernel.org>
2024-05-01objpool: enable inlining objpool_push() and objpool_pop() operationsAndrii Nakryiko
objpool_push() and objpool_pop() are very performance-critical functions and can be called very frequently in kretprobe triggering path. As such, it makes sense to allow compiler to inline them completely to eliminate function calls overhead. Luckily, their logic is quite well isolated and doesn't have any sprawling dependencies. This patch moves both objpool_push() and objpool_pop() into include/linux/objpool.h and marks them as static inline functions, enabling inlining. To avoid anyone using internal helpers (objpool_try_get_slot, objpool_try_add_slot), rename them to use leading underscores. We used kretprobe microbenchmark from BPF selftests (bench trig-kprobe and trig-kprobe-multi benchmarks) running no-op BPF kretprobe/kretprobe.multi programs in a tight loop to evaluate the effect. BPF own overhead in this case is minimal and it mostly stresses the rest of in-kernel kretprobe infrastructure overhead. Results are in millions of calls per second. This is not super scientific, but shows the trend nevertheless.

2024-05-01ftrace: make extra rcu_is_watching() validation check optionalAndrii Nakryiko
Introduce CONFIG_FTRACE_VALIDATE_RCU_IS_WATCHING config option to control whether ftrace low-level code performs additional rcu_is_watching()-based validation logic in an attempt to catch noinstr violations. This check is expected to never be true and is mostly useful for low-level validation of ftrace subsystem invariants. For most users it should probably be kept disabled to eliminate unnecessary runtime overhead. This improves BPF multi-kretprobe (relying on ftrace and rethook infrastructure) runtime throughput by 2%, according to BPF benchmarks ([0]).

2024-04-30cxl/core: Add region info to cxl_general_media and cxl_dram eventsAlison Schofield
User space may need to know which region, if any, maps the DPAs (device physical addresses) reported in a cxl_general_media or cxl_dram event. Since the mapping can change, the kernel provides this information at the time the event occurs. This informs user space that at event <timestamp> this <region> mapped this <DPA> to this <HPA>. Add the same region info that is included in the cxl_poison trace event: the DPA->HPA translation, region name, and region uuid. The new fields are inserted in the trace event and no existing fields are modified. If the DPA is not mapped, user will see: hpa=ULLONG_MAX, region="", and uuid=0 This work must be protected by dpa_rwsem & region_rwsem since it is looking up region mappings.

2024-04-30powercap: intel_rapl: Introduce APIs for PMU supportZhang Rui
Introduce two new APIs rapl_package_add_pmu()/rapl_package_remove_pmu(). RAPL driver can invoke these APIs to expose its supported energy counters via perf PMU. The new RAPL PMU is fully compatible with current MSR RAPL PMU, including using the same PMU name and events name/id/unit/scale, etc. For example, use below command perf stat -e power/energy-pkg/ -e power/energy-ram/ FOO to get the energy consumption if power/energy-pkg/ and power/energy-ram/ events are available in the "perf list" output. This does not introduce any conflict because TPMI RAPL is the only user of these APIs currently, and it never co-exists with MSR RAPL. Note that RAPL Packages can be probed/removed dynamically, and the events supported by each TPMI RAPL device can be different. Thus the RAPL PMU support is done on demand, which means 1. PMU is registered only if it is needed by a RAPL Package. PMU events for unsupported counters are not exposed. 2. PMU is unregistered and registered when a new RAPL Package is probed and supports new counters that are not supported by current PMU. For example, on a dual-package system using TPMI RAPL, it is possible that Package 1 behaves as TPMI domain root and supports Psys domain. In this case, register PMU without Psys event when probing Package 0, and re-register the PMU with Psys event when probing Package 1. 3. PMU is unregistered when all registered RAPL Packages don't need PMU. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Currently, cxl-event.h is only used by drivers/cxl/cxlmem.h, and it doesn't cause any errors because cxlmem.h indirectly includes the required types. However, cxl-event.h may be used by other CXL-related code in the future, so it's important to fix this issue by including the missing header files directly in cxl-event.h.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A updates for v6.10 1. Support for handling notification pending interrupt(NPI) The FF-A uses the notification pending interrupt to inform the receiver that it has a pending notification. This is a virtual interrupt and is used by the following type of receivers: - A guest/VM running under a hypervisor(normal world usecase) - An S-EL1 SP running under a S-EL2 SPMC(secure world only usecase) Also, when the FF-A driver is running inside a guest VM under an hypervisor, the driver/guest VM doesn't have the permission/capability to request the creation of notification bitmaps. For a VM, the hypervisor reserves memory for its VM and hypervisor framework notification bitmaps and the SPMC reserves memory for its SP and SPMC framework notification bitmaps before the hypervisor initializes it. These changes include skipping of creation of notification bitmaps, some refactoring around schedule receiver interrupt(SRI) handling and addition of support for NPI. 2. Support for FF-A indirect messaging The FFA_MSG_SEND2 can be used to transmit a partition message from the Tx buffer of the sender(the driver in this case) endpoint to the Rx buffer of the receiver endpoint and inform the scheduler that the receiver endpoint must be run. Apart from these two main features, there is an optimisation to avoid queuing of a work when already running on the worker queue. * tag 'ffa-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Avoid queuing work when running on the worker queue firmware: arm_ffa: Fix memory corruption in ffa_msg_send2() firmware: arm_ffa: Add support for FFA_MSG_SEND2 firmware: arm_ffa: Stash the partition properties for query purposes firmware: arm_ffa: Fix kernel warning about incorrect SRI/NPI firmware: arm_ffa: Add support for handling notification pending interrupt(NPI) firmware: arm_ffa: Refactor SRI handling in prepartion to add NPI support firmware: arm_ffa: Skip creation of the notification bitmaps Link: https://lore.kernel.org/r/20240426105051.1527016-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.10 1. Basic support for SCMI v3.2 pincontrol protocol SCMI v3.2 introduces pincontrol protocol which is intended for controlling pins and their configuration. The pin control protocol provides commands to: - List the pins, groups of pins, available functions, and their association with each other. - Set the parameter configuration and multiplexing of the pins or groups of pins - Optionally request exclusive access to a pin or group of pins. - Optionally configure the permissions of an agent to access a pin or group of pins. These changes adds basic support for the same in the SCMI core layer and an implementation of the generic scmi-pinctrl driver with associated DT bindings. 2. Framework support for multiple vendors custom protocols With the fixed space for vendor protocols, the possibility of having multiple vendors implementing distinct SCMI vendor protocols with the same overlapping protocol number is very high and with the need to support them all in a single kernel image or a module is also high. In order to implement the same we assume: - vendor protocols has to be tagged at build time with a vendor_id - vendor protocols could also optionally be tagged at build time with sub_vendor_id and implementation version At the initialisation all the built vendor protocols are registered with the SCMI core using a key derived from the above tags 3. Logging and tracing improvements This includes using dev_err_probe() to bail out from probe, adding message dump traces for bad and unexpected replies and widening of the tag buffer in trace_scmi_dump_msg to allow diverse tag names 4. Miscellaneous updates or improvements This includes adding the accessor function get_max_msg_size() used in pinctl protocol, updation of dt-bindings examples for protocol@13 to promote new bindings and simplification of scmi_devm_notifier_unregister * tag 'scmi-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: pinctrl: Implementation of the generic scmi-pinctrl driver firmware: arm_scmi: Add basic support for SCMI v3.2 pincontrol protocol dt-bindings: firmware: Support SCMI pinctrl protocol firmware: arm_scmi: Introduce get_max_msg_size() helper/accessor firmware: arm_scmi: Add support for multiple vendors custom protocols dt-bindings: firmware: arm,scmi: Update examples for protocol@13 firmware: arm_scmi: Avoid non-constant printk format strings firmware: arm_scmi: Use dev_err_probe to bail out firmware: arm_scmi: Simplify scmi_devm_notifier_unregister firmware: arm_scmi: Add message dump traces for bad and unexpected replies firmware: arm_scmi: Add helper to trace bad messages include: trace: Widen the tag buffer in trace_scmi_dump_msg firmware: arm_scmi: Log the perf domain names in the error paths Link: https://lore.kernel.org/r/20240426105031.1526987-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into soc/drivers STM32 Firewall bus for v6.10, round 1 Highlights: --------- Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers register to the framework to offer firewall services such as access granting. This series of patches is a new approach on the previous STM32 system bus, history is available here: https://lore.kernel.org/lkml/20230127164040.1047583/ The need for such framework arises from the fact that there are now multiple hardware firewalls implemented across multiple products. Drivers are shared between different products, using the same code. When it comes to firewalls, the purpose mostly stays the same: Protect hardware resources. But the implementation differs, and there are multiple types of firewalls: peripheral, memory, ... Some hardware firewall controllers such as the RIFSC implemented on STM32MP2x platforms may require to take ownership of a resource before being able to use it, hence the requirement for firewall services to take/release the ownership of such resources. On the other hand, hardware firewall configurations are becoming more and more complex. These mecanisms prevent platform crashes or other firewall-related incoveniences by denying access to some resources. The stm32 firewall framework offers an API that is defined in firewall controllers drivers to best fit the specificity of each firewall. For every peripherals protected by either the ETZPC or the RIFSC, the firewall framework checks the firewall controlelr registers to see if the peripheral's access is granted to the Linux kernel. If not, the peripheral is configured as secure, the node is marked populated, so that the driver is not probed for that device. The firewall framework relies on the access-controller device tree binding. It is used by peripherals to reference a domain access controller. In this case a firewall controller. The bus uses the ID referenced by the access-controller property to know where to look in the firewall to get the security configuration for the peripheral. This allows a device tree description rather than a hardcoded peripheral table in the bus driver. The STM32 ETZPC device is responsible for filtering accesses based on security level, or co-processor isolation for any resource connected to it. The RIFSC is responsible for filtering accesses based on Compartment ID / security level / privilege level for any resource connected to it. * tag 'stm32-bus-firewall-for-v6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32: bus: stm32_firewall: fix off by one in stm32_firewall_get_firewall() bus: etzpc: introduce ETZPC firewall controller driver bus: rifsc: introduce RIFSC firewall controller driver of: property: fw_devlink: Add support for "access-controller" firewall: introduce stm32_firewall framework dt-bindings: bus: document ETZPC dt-bindings: bus: document RIFSC dt-bindings: treewide: add access-controllers description dt-bindings: document generic access controllers Link: https://lore.kernel.org/r/7dc64226-5429-4ab7-a8c8-6053b12e3cf5@foss.st.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2024-04-29iio: backend: add API for interface tuningNuno Sa
This is in preparation for supporting interface tuning in one for the devices using the axi-adc backend. The new added interfaces are all needed for that calibration: * iio_backend_test_pattern_set(); * iio_backend_chan_status(); * iio_backend_iodelay_set(); * iio_backend_data_sample_trigger(). Interface tuning is the process of going through a set of known points (typically by the frontend), change some clk or data delays (or both) and send/receive some known signal (so called test patterns in this change). The receiving end (either frontend or the backend) is responsible for validating the signal and see if it's good or not. The goal for all of this is to come up with ideal delays at the data interface level so we can have a proper, more reliable data transfer. Also note that for some devices we can change the sampling rate (which typically means changing some reference clock) and that can affect the data interface. In that case, it's import to run the tuning algorithm again as the values we had before may no longer be the best (or even valid) ones.

2024-04-29iio: core: Add iio_read_acpi_mount_matrix() helper functionHans de Goede
The ACPI "ROTM" rotation matrix parsing code atm is already duplicated between bmc150-accel-core.c and kxcjk-1013.c and a third user of this is coming. Add an iio_read_acpi_mount_matrix() helper function for this. The 2 existing copies of the code are identical, except that the kxcjk-1013.c has slightly better error logging. To new helper is a 1:1 copy of the kxcjk-1013.c version, the only change is the addition of a "char *acpi_method" parameter since some bmc150 dual-accel setups (360° hinges with 1 accel in kbd/base + 1 in display) declare both accels in a single ACPI device with 2 different method names for the 2 matrices. This new acpi_method parameter is not "const char *" because the pathname parameter to acpi_evaluate_object() is not const. The 2 existing copies of this function will be removed in further patches in this series. Acked-by: Rafael J.

2024-04-29netfs: Replace PG_fscache by setting folio->private and marking dirtyDavid Howells
When dirty data is being written to the cache, setting/waiting on/clearing the fscache flag is always done in tandem with setting/waiting on/clearing the writeback flag. The netfslib buffered write routines wait on and set both flags and the write request cleanup clears both flags, so the fscache flag is almost superfluous. The reason it isn't superfluous is because the fscache flag is also used to indicate that data just read from the server is being written to the cache. The flag is used to prevent a race involving overlapping direct-I/O writes to the cache. Change this to indicate that a page is in need of being copied to the cache by placing a magic value in folio->private and marking the folios dirty. Then when the writeback code sees a folio marked in this way, it only writes it to the cache and not to the server. If a folio that has this magic value set is modified, the value is just replaced and the folio will then be uplodaded too. With this, PG_fscache is no longer required by the netfslib core, 9p and afs. Ceph and nfs, however, still need to use the old PG_fscache-based tracking. To deal with this, a flag, NETFS_ICTX_USE_PGPRIV2, now has to be set on the flags in the netfs_inode struct for those filesystems. This reenables the use of PG_fscache in that inode. 9p and afs use the netfslib write helpers so get switched over; cifs, for the moment, does page-by-page manual access to the cache, so doesn't use PG_fscache and is unaffected.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Arnd Bergmann: "There are a lot of minor DT fixes for Mediatek, Rockchip, Qualcomm and Microchip and NXP, addressing both build-time warnings and bugs found during runtime testing. Most of these changes are machine specific fixups, but there are a few notable regressions that affect an entire SoC: - The Qualcomm MSI support that was improved for 6.9 ended up being wrong on some chips and now gets fixed. - The i.MX8MP camera interface broke due to a typo and gets updated again. The main driver fix is also for Qualcomm platforms, rewriting an interface in the QSEECOM firmware support that could lead to crashing the kernel from a trusted application. The only other code changes are minor fixes for Mediatek SoC drivers" * tag 'soc-fixes-6.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (50 commits) ARM: dts: imx6ull-tarragon: fix USB over-current polarity soc: mediatek: mtk-socinfo: depends on CONFIG_SOC_BUS soc: mediatek: mtk-svs: Append "-thermal" to thermal zone names arm64: dts: imx8mp: Fix assigned-clocks for second CSI2 ARM: dts: microchip: at91-sama7g54_curiosity: Replace regulator-suspend-voltage with the valid property ARM: dts: microchip: at91-sama7g5ek: Replace regulator-suspend-voltage with the valid property arm64: dts: rockchip: Fix USB interface compatible string on kobol-helios64 arm64: dts: qcom: sc8180x: Fix ss_phy_irq for secondary USB controller arm64: dts: qcom: sm8650: Fix the msi-map entries arm64: dts: qcom: sm8550: Fix the msi-map entries arm64: dts: qcom: sm8450: Fix the msi-map entries arm64: dts: qcom: sc8280xp: add missing PCIe minimum OPP arm64: dts: qcom: x1e80100: Fix the compatible for cluster idle states arm64: dts: qcom: Fix type of "wdog" IRQs for remoteprocs arm64: dts: rockchip: regulator for sd needs to be always on for BPI-R2Pro dt-bindings: rockchip: grf: Add missing type to 'pcie-phy' node arm64: dts: rockchip: drop redundant disable-gpios in Lubancat 2 arm64: dts: rockchip: drop redundant disable-gpios in Lubancat 1 arm64: dts: rockchip: drop redundant pcie-reset-suspend in Scarlet Dumo arm64: dts: rockchip: mark system power controller and fix typo on orangepi-5-plus ...

2024-04-26pwm: Add a struct device to struct pwm_chipUwe Kleine-König
This replaces the formerly dynamically allocated struct device. This allows to additionally use it to track the lifetime of the struct pwm_chip. Otherwise the new struct device provides the same sysfs API as was provided by the dynamic device before.

2024-04-26pwm: Ensure a struct pwm has the same lifetime as its pwm_chipUwe Kleine-König
It's required to not free the memory underlying a requested PWM while a consumer still has a reference to it. While currently a pwm_chip doesn't live long enough in all cases, linking the struct pwm to the pwm_chip results in the right lifetime as soon as the pwmchip is living long enough. This happens with the following commits. Note this is a breaking change for all pwm drivers that don't use pwmchip_alloc(). Reviewed-by: Gustavo A. R.
