ACPI: processor: perflib: Avoid updating frequency QoS unnecessarily

2022-12-30T18:10:02Z

Modify acpi_processor_get_platform_limit() to avoid updating its frequency QoS request when the _PPC return value has not changed by comparing that value to the previous _PPC return value stored in the performance_platform_limit field of the struct acpi_processor corresponding to the given CPU. While at it, do the _PPC return value check against the state count earlier, to avoid setting performance_platform_limit to an invalid value, and make acpi_processor_ppc_init() use FREQ_QOS_MAX_DEFAULT_VALUE as the "no limit" frequency QoS for consistency.

ACPI: processor: perflib: Use the "no limit" frequency QoS

2022-12-30T18:10:02Z

When _PPC returns 0, it means that the CPU frequency is not limited by the platform firmware, so make acpi_processor_get_platform_limit() update the frequency QoS request used by it to "no limit" in that case. This addresses a problem with limiting CPU frequency artificially on some systems after CPU offline/online to the frequency that corresponds to the first entry in the _PSS return package.

ACPI: processor: perflib: Adjust acpi_processor_notify_smm() return value

2022-12-07T17:09:39Z

Avoid returning a confusing error code from acpi_processor_notify_smm() if it is called for the second time in the case when SMM notification regarding P-state control is not supported. Signed-off-by: Rafael J. Wysocki

ACPI: processor: perflib: Rearrange acpi_processor_notify_smm()

2022-12-07T17:09:39Z

Rearrange the code in acpi_processor_notify_smm() to consolidate error handling in it and improve the comments in there while at it. No expected functional impact. Signed-off-by: Rafael J. Wysocki

ACPI: processor: perflib: Rearrange unregistration routine

2022-12-07T17:09:39Z

Rearrange acpi_processor_unregister_performance() to follow a more common error handling pattern and drop a redundant "return" statement from the end of it. No expected functional impact. Signed-off-by: Rafael J. Wysocki

ACPI: processor: perflib: Drop redundant parentheses

2022-12-07T17:09:39Z

Drop some redundant parentheses and rearrange some checks using them in the ACPI processor performance library code for better code clarity. No expected functional impact. Signed-off-by: Rafael J. Wysocki

ACPI: processor: perflib: Adjust white space

2022-12-07T17:09:39Z

Some inconsistent usage of white space in the ACPI processor performance library code causes that code to be somewhat harder to read that it would have been otherwise, so adjust the white space in there to address that. No expected functional impact. Signed-off-by: Rafael J. Wysocki

ACPI: processor_perflib: Cleanup print messages

2021-06-07T13:36:46Z

The log messages in processor_perflib.c is not in consistency, we have some printk() calls with PREFIX, but some are not; we use pr_*() functions without prefix. So add pr_fmt() and unify them with pr_*() functions. While at it, fix some obvious coding style issues when going through the functions. Signed-off-by: Hanjun Guo Signed-off-by: Rafael J. Wysocki
