thermal: int3403_thermal: Downgrade error message

2020-07-22T07:33:15+00:00

commit f3d7fb38976b1b0a8462ba1c7cbd404ddfaad086 upstream. Downgrade "Unsupported event" message from dev_err to dev_dbg to avoid flooding with this message on some platforms.

thermal: intel: Use dev_get_drvdata

2019-09-24T01:55:51+00:00

Instead of using to_pci_dev + pci_get_drvdata, use dev_get_drvdata to make code simpler. Signed-off-by: Chuhong Yuan Signed-off-by: Zhang Rui

thermal: intel: int3403: replace printk(KERN_WARN...) with pr_warn(...)

2019-09-24T01:53:03+00:00

Direct invocation of printk() is not preferred to emit logs. This commit replaces printk(KERN_WARNING) with corresponding pr_warn() function call. Signed-off-by: Rishi Gupta Signed-off-by: Zhang Rui

thermal: intel: int340x_thermal: Remove unnecessary acpi_has_method() uses

2019-09-24T01:53:03+00:00

acpi_evaluate_object() will already return in error if the method does not exist. Checking if the method is absent before the acpi_evaluate_object() call is not needed. Remove acpi_has_method() calls to avoid additional work. Signed-off-by: Kelsey Skunberg Reviewed-by: Rafael J. Wysocki Signed-off-by: Zhang Rui

thermal: int340x: processor_thermal: Add Ice Lake support

2019-09-24T01:53:03+00:00

Add new PCI id for Ice lake processor thermal device. Also enabled the RAPL mmio interface. The MMIO offsets match Skylake. Signed-off-by: Srinivas Pandruvada Signed-off-by: Zhang Rui

cpuidle: play_idle: Increase the resolution to usec

2019-09-03T09:33:29+00:00

The play_idle resolution is 1ms. The intel_powerclamp bases the idle duration on jiffies. The idle injection API is also using msec based duration but has no user yet. Unfortunately, msec based time does not fit well when we want to inject idle cycle precisely with shallow idle state. In order to set the scene for the incoming idle injection user, move the precision up to usec when calling play_idle. Signed-off-by: Daniel Lezcano Signed-off-by: Rafael J. Wysocki

drivers: thermal: processor_thermal_device: Export sysfs interface for TCC offset

2019-08-19T06:56:12+00:00

This change exports an interface to read tcc offset and allow writing if the platform is not locked. Refer to Intel SDM for details on the MSR: MSR_TEMPERATURE_TARGET. Here TCC Activation Offset (R/W) bits allow temperature offset in degrees in relation to TjMAX. This change will be useful for improving performance from user space for some platforms, if the current offset is not optimal.

int340X/processor_thermal_device: Fix proc_thermal_rapl_remove()

2019-07-23T07:36:07+00:00

Passing 0 to cpuhp_remove_state() triggers the BUG_ON() in __cpuhp_remove_state_cpuslocked() and the argument passed to powercap_unregister_control_type() is expected to be a valid pointer, so avoid calling these functions with incorrect arguments from proc_thermal_rapl_remove().

Pull more power management updates from Rafael Wysocki: "These modify the Intel RAPL driver to allow it to use an MMIO interface to the hardware, make the int340X thermal driver provide such an interface for it, add Intel Ice Lake CPU IDs to the RAPL driver (these changes depend on the previously merged x86 arch changes), update cpufreq to use the PM QoS framework for managing the min and max frequency limits, and add update the imx-cpufreq-dt cpufreq driver to support i.MX8MN. Specifics: - Add MMIO interface support to the Intel RAPL power capping driver and update the int340X thermal driver to provide a RAPL MMIO interface (Zhang Rui, Stephen Rothwell). - Add Intel Ice Lake CPU IDs to the RAPL driver (Zhang Rui, Rajneesh Bhardwaj). - Make cpufreq use the PM QoS framework (instead of notifiers) for managing the min and max frequency constraints (Viresh Kumar). - Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson Huang)" * tag 'pm-5.3-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (27 commits) cpufreq: Make cpufreq_generic_init() return void intel_rapl: need linux/cpuhotplug.h for enum cpuhp_state powercap/rapl: Add Ice Lake NNPI support to RAPL driver powercap/intel_rapl: add support for ICX-D powercap/intel_rapl: add support for ICX powercap/intel_rapl: add support for IceLake desktop intel_rapl: Fix module autoloading issue int340X/processor_thermal_device: add support for MMIO RAPL intel_rapl: support two power limits for every RAPL domain intel_rapl: support 64 bit register intel_rapl: abstract RAPL common code intel_rapl: cleanup hardcoded MSR access intel_rapl: cleanup some functions intel_rapl: abstract register access operations intel_rapl: abstract register address intel_rapl: introduce struct rapl_if_private intel_rapl: introduce intel_rapl.h intel_rapl: remove hardcoded register index intel_rapl: use reg instead of msr cpufreq: imx-cpufreq-dt: Add i.MX8MN support ...
