2022-05-22hwmon: Make chip parameter for with_info API mandatoryGuenter Roeck2-10/+8
Various attempts were made recently to "convert" the old hwmon_device_register() API to devm_hwmon_device_register_with_info() by just changing the function name without actually converting the driver. Prevent this from happening by making the 'chip' parameter of devm_hwmon_device_register_with_info() mandatory. Signed-off-by: Guenter Roeck <[email protected]>
2022-05-22thermal/drivers/thermal_hwmon: Use hwmon_device_register_for_thermal()Guenter Roeck1-2/+4
The thermal subsystem registers a hwmon device without providing chip information or sysfs attribute groups. While undesirable, it would be difficult to change. On the other side, it abuses the hwmon_device_register_with_info API by not providing that information. Use new API specifically created for the thermal subsystem instead to let us enforce the 'chip' parameter for other callers of hwmon_device_register_with_info(). Acked-by: Rafael J .

2022-05-22hwmon: Introduce hwmon_device_register_for_thermalGuenter Roeck2-0/+28
The thermal subsystem registers a hwmon driver without providing chip or sysfs group information. This is for legacy reasons and would be difficult to change. At the same time, we want to enforce that chip information is provided when registering a hwmon device using hwmon_device_register_with_info(). To enable this, introduce a special API for use only by the thermal subsystem. Acked-by: Rafael J . Wysocki <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>

2022-05-22hwmon: (nct6775) Add i2c driverZev Weiss4-0/+220
This driver provides an i2c I/O mechanism for the core nct6775 driver, as might be used by a BMC. Because the Super I/O chip is shared with the host CPU in such a scenario (and the host should ultimately be in control of it), the i2c driver is strictly read-only to avoid interfering with any usage by the host (aside from the bank-select register, which seems to be replicated for the i2c interface).

Some include directives are no longer necessary due to previous driver changes. Remove them now to further improve driver code clarity. Mutex usage has ceased since commit 719af4f1a40b ("hwmon: (lm83) Use regmap"). Ever since commit a0ac840d99fa ("hwmon: (lm83) Convert to use devm_hwmon_device_register_with_groups") functions sysfs_create_group and sysfs_remove_group are no longer used by the driver.

2022-05-22hwmon: (pmbus) Register with thermal for PSC_TEMPERATUREEduardo Valentin1-0/+68
Some pmbus device drivers have device tree support and may want to use of-thermal to register a thermal zone OF sensor for those device drivers. This way we allow describing device tree thermal zones for pmbus device drivers with device tree support. This patch achieves this by registering pmbus sensors with thermal subsystem if they are PSC_TEMPERATURE and are providing _input hwmon interface.

2022-05-21perf test: Fix "all PMU test" to skip hv_24x7/hv_gpci tests on powerpcAthira Rajeev1-0/+10
"perf all PMU test" picks the input events from "perf list --raw-dump pmu" list and runs "perf stat -e" for each of the event in the list. In case of powerpc, the PowerVM environment supports events from hv_24x7 and hv_gpci PMU which is of example format like below: - hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/ - hv_gpci/event,partition_id=?/ The value for "?" needs to be filled in depending on system and respective event. CPM_ADJUNCT_INST needs have core value and domain value. hv_gpci event needs partition_id. Similarly, there are other events for hv_24x7 and hv_gpci having "?" in event format. Hence skip these events on powerpc platform since values like partition_id, domain is specific to system and event.

2022-05-21io_uring: cleanup handling of the two task_work listsJens Axboe1-25/+37
Rather than pass in a bool for whether or not this work item needs to go into the priority list or not, provide separate helpers for it. For most use cases, this also then gets rid of the branch for non-priority task work. While at it, rename the prior_task_list to prio_task_list. Prior is a confusing name for it, as it would seem to indicate that this is the previous task_work list. prio makes it clear that this is a priority task_work list.

2022-05-21i2c: ismt: Provide a DMA buffer for Interrupt Cause LoggingMika Westerberg1-0/+14
Before sending a MSI the hardware writes information pertinent to the interrupt cause to a memory location pointed by SMTICL register. This memory holds three double words where the least significant bit tells whether the interrupt cause of master/target/error is valid. The driver does not use this but we need to set it up because otherwise it will perform DMA write to the default address (0) and this will cause an IOMMU fault such as below: DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Write] Request device [00:12.0] PASID ffffffff fault addr 0 [fault reason 05] PTE Write access is not set To prevent this from happening, provide a proper DMA buffer for this that then gets mapped by the IOMMU accordingly.

2022-05-20perf: Fix sys_perf_event_open() race against selfPeter Zijlstra1-0/+14
Norbert reported that it's possible to race sys_perf_event_open() such that the looser ends up in another context from the group leader, triggering many WARNs. The move_group case checks for races against itself, but the !move_group case doesn't, seemingly relying on the previous group_leader->ctx == ctx check. However, that check is racy due to not holding any locks at that time. Therefore, re-check the result after acquiring locks and bailing if they no longer match. Additionally, clarify the not_move_group case from the move_group-vs-move_group race.

2022-05-20hwmon: (pmbus/ltc2978) Add chip specific write_byte_dataMårten Lindahl1-0/+12
Several of the manuals for devices supported by this driver describes the need for a minimum wait time before the chip is ready to receive next command. This wait time is already implemented in the driver as a ltc_wait_ready function with a driver defined wait time of 100 ms, and is considered for specific devices before reading/writing data on the pmbus. Since this driver uses the default pmbus_regulator_ops for the enable/ disable/is_enabled functions we should add a driver specific callback for write_byte_data to prevent bypassing the wait time recommendations for the following devices: ltc3880/ltc3882/ltc3883/ltc3884/ltc3886/ ltc3887/ltc3889/ltm4664/ltm4675/ltm4676/ltm4677/ltm4678/ltm4680/ltm4686/ ltm4700/ltc7880.
