cpufreq: intel_pstate: Fix active mode setting from command line

2020-07-13T15:55:57Z

If intel_pstate starts in the passive mode by default (that happens when the processor in the system doesn't support HWP), passing intel_pstate=active in the kernel command line doesn't work, so fix that. Fixes: 33aa46f252c7 ("cpufreq: intel_pstate: Use passive mode by default without HWP") Reported-by: Doug Smythies Signed-off-by: Rafael J. Wysocki Acked-by: Doug Smythies

cpufreq: intel_pstate: Add one more OOB control bit

2020-06-23T15:24:32Z

Add one more bit for OOB (Out Of Band) enabling of P-states. If OOB handling of P-states is enabled, intel_pstate shouldn't load. Currently, only "BIT(8) == 1" of the MSR MSR_MISC_PWR_MGMT is considered as OOB, but "BIT(18) == 1" needs to be taken into consideration as OOB condition too.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

cpufreq: CPPC: add SW BOOST support

2020-06-05T12:20:02Z

To add SW BOOST support for CPPC, we need to get the max frequency of boost mode and non-boost mode. ACPI spec 6.2 section 8.4.7.1 describes the following two CPC registers. "Highest performance is the absolute maximum performance an individual processor may reach, assuming ideal conditions. This performance level may not be sustainable for long durations, and may only be achievable if other platform components are in a specific state; for example, it may require other processors be in an idle state. Nominal Performance is the maximum sustained performance level of the processor, assuming ideal operating conditions. In absence of an external constraint (power, thermal, etc.) this is the performance level the platform is expected to be able to maintain continuously. All processors are expected to be able to sustain their nominal performance state simultaneously." To add SW BOOST support for CPPC, we can use Highest Performance as the max performance in boost mode and Nominal Performance as the max performance in non-boost mode. If the Highest Performance is greater than the Nominal Performance, we assume SW BOOST is supported. The current CPPC driver does not support SW BOOST and use 'Highest Performance' as the max performance the CPU can achieve. 'Nominal Performance' is used to convert 'performance' to 'frequency'. That means, if firmware enable boost and provide a value for Highest Performance which is greater than Nominal Performance, boost feature is enabled by default. Because SW BOOST is disabled by default, so, after this patch, boost feature is disabled by default even if boost is enabled by firmware.

cpufreq: change '.set_boost' to act on one policy

2020-06-05T12:20:02Z

Macro 'for_each_active_policy()' is defined internally. To avoid some cpufreq driver needing this macro to iterate over all the policies in '.set_boost' callback, we redefine '.set_boost' to act on only one policy and pass the policy as an argument. 'cpufreq_boost_trigger_state()' iterates over all the policies to set boost for the system. This is preparation for adding SW BOOST support for CPPC. To protect Boost enable/disable by sysfs from CPU online/offline, add 'cpu_hotplug_lock' before calling '.set_boost' for each CPU. Also move the lock from 'set_boost()' to 'store_cpb()' in acpi_cpufreq.
