2024-05-13ARC: Add eBPF JIT supportShahab Vahedi1-0/+6
This will add eBPF JIT support to the 32-bit ARCv2 processors. The implementation is qualified by running the BPF tests on a Synopsys HSDK board with "ARC HS38 v2.1c at 500 MHz" as the 4-core CPU. The test_bpf.ko reports 2-10 fold improvements in execution time of its tests. For instance: test_bpf: #33 tcpdump port 22 jited:0 704 1766 2104 PASS test_bpf: #33 tcpdump port 22 jited:1 120 224 260 PASS test_bpf: #141 ALU_DIV_X: 4294967295 / 4294967295 = 1 jited:0 238 PASS test_bpf: #141 ALU_DIV_X: 4294967295 / 4294967295 = 1 jited:1 23 PASS test_bpf: #776 JMP32_JGE_K: all ... magnitudes jited:0 2034681 PASS test_bpf: #776 JMP32_JGE_K: all ... magnitudes jited:1 1020022 PASS Deployment and structure ------------------------ The related codes are added to "arch/arc/net": - bpf_jit.h -- The interface that a back-end translator must provide - bpf_jit_core.c -- Knows how to handle the input eBPF byte stream - bpf_jit_arcv2.c -- The back-end code that knows the translation logic The bpf_int_jit_compile() at the end of bpf_jit_core.c is the entrance to the whole process. Normally, the translation is done in one pass, namely the "normal pass". In case some relocations are not known during this pass, some data (arc_jit_data) is allocated for the next pass to come. This possible next (and last) pass is called the "extra pass". 1. Normal pass # The necessary pass 1a. Dry run # Get the whole JIT length, epilogue offset, etc. 1b. Emit phase # Allocate memory and start emitting instructions 2. Extra pass # Only needed if there are relocations to be fixed 2a. Patch relocations Support status -------------- The JIT compiler supports BPF instructions up to "cpu=v4". However, it does not yet provide support for: - Tail calls - Atomic operations - 64-bit division/remainder - BPF_PROBE_MEM* (exception table) The result of "test_bpf" test suite on an HSDK board is: hsdk-lnx# insmod test_bpf.ko test_suite=test_bpf test_bpf: Summary: 863 PASSED, 186 FAILED, [851/851 JIT'ed] All the failing test cases are due to the ones that were not JIT'ed.

2024-05-06i2c: add zhaoxin i2c controller driverHans Hu1-0/+8
Add Zhaoxin I2C controller driver. It provides the access to the i2c busses, which connects to the touchpad, eeprom, I2S, etc. Zhaoxin I2C controller has two separate busses, so may accommodate up to two I2C adapters. Those adapters are listed in the ACPI namespace with the IIC1D17 HID, and probed by a platform driver. The driver works with IRQ mode, and supports basic I2C features. Flags I2C_AQ_NO_ZERO_LEN and I2C_AQ_COMB_WRITE_THEN_READ are used to limit the unsupported access.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. get_maintainer.pl can only return commit_signer history for file include/linux/einj-cxl.h because the entry in MAINTAINERS is wrong. Correct the entry so that the full MAINTAINER list is returned. Repair the file entry in COMPUTE EXPRESS LINK (CXL).

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>

The project hosts the reference implementation of Arm Platform Security Architecture [3] for Arm A-profile devices. The FF-A Secure Partitions are accessible through the FF-A driver in Linux. However, the FF-A driver doesn't have a user space interface so user space clients currently cannot access Trusted Services.

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.10 The Qualcomm SCM driver initialization order is improved, to avoid any potential for a client to find a half-initialized SCM instance. The handling of download mode bits is updated to not attempt QCOM_SCM_BOOT_SET_DLOAD_MODE if a io-address for the update is specified, and that path is changed to perform a read-modify-write to avoid updating unrelated bits. Error handling is corrected in the peripheral authentication service (PAS) functions, to release interconnect bandwidth votes in the case of an error. An unwanted error print on allocation error is also removed from this code path. The QSEECOM allow list is marked __maybe_unused to avoid build warnings when built with !OF. The error handling related to the interconnect API is cleaned up to avoid handling the impossible IS_ERR() condition. initcall level is bumped to "core" for cmd-db and rpmh-rsc, as dependent drivers like regulators, interconnects and clocks are registered at this level. Another attempt is made to remove the strncpy() usage in cmd-db, this time with strtomem_pad() which has the correct characteristics. The bwmon regmap cache is changed to maple tree. After an attempt to add missing MODULE_DEVICE_TABLEs to debug drivers, the intention of not having them automatically load is documented. Operations on the pmic_glink client list is put under mutual exclusion, to avoid races when clients are being registered. pmic_glink client registered after the firmware notification arrived was not informed that the firmware was up, this is resolved. More DSPs and the apss subsystem is added to the Qualcomm sleep stats driver. Checks for in-flight regulator requests in the RPMh RSC driver is improved to deal with the fact that these occupy multiple registers, so it's insufficient to just to direct address comparison. The socinfo drivers learns about X1 Elite and SMB2360 PMIC. The maintainers entry is split between the linux-arm-msm list and subset that is maintained in the qcom-soc tree, to avoid some confusion about maintainership. * tag 'qcom-drivers-for-6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (21 commits) soc: qcom: cmd-db: replace deprecated strncpy with strtomem soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request firmware: qcom: scm: Modify only the download bits in TCSR register firmware: qcom: scm: Fix __scm and waitq completion variable initialization firmware: qcom: scm: Rework dload mode availability check firmware: qcom: scm: Remove redundant scm argument from qcom_scm_waitq_wakeup() firmware: qcom: scm: Remove log reporting memory allocation failure soc: qcom: pmic_glink: notify clients about the current state soc: qcom: pmic_glink: don't traverse clients list without a lock soc: qcom: mention intentionally broken module autoloading firmware: qcom: qcm: fix unused qcom_scm_qseecom_allowlist MAINTAINERS: Split Qualcomm SoC and linux-arm-msm entries soc: qcom: qcom_stats: Add DSPs and apss subsystem stats dt-bindings: soc: qcom: qcom,pmic-glink: document QCM6490 compatible soc: qcom: socinfo: Add SMB2360 PMIC soc: qcom: socinfo: Add X1E80100 SoC ID table entry dt-bindings: arm: qcom,ids: Add SoC ID for X1E80100 soc: qcom: Update init level to core_initcall() for cmd-db and rpmh-rsc soc: qcom: icc-bwmon: Convert to use maple tree register cache firmware: qcom_scm: remove IS_ERR() checks from qcom_scm_bw_{en,dis}able() ...

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>

Add a new driver for the MSI WMI Platform interface. The underlying ACPI WMI interface supports many features, but so far only reading of fan speed sensors is implemented. The driver was reverse-engineered based on a user request to the lm-sensors project, see the github issue for details. The ACPI WMI interface used by this driver seems to use the same embedded controller interface as the msi-ec driver, but supports automatic discovery of supported machines without relying on a DMI whitelist.
