tweewide: Fix most Shebang lines

2021-05-22T09:38:30+00:00

commit c25ce589dca10d64dde139ae093abc258a32869c upstream. Change every shebang which does not need an argument to use /usr/bin/env. This is needed as not every distro has everything under /usr/bin, sometimes not even bash. Signed-off-by: Finn Behrens Signed-off-by: Masahiro Yamada Signed-off-by: Greg Kroah-Hartman

[ Upstream commit 1f81c5efc020314b2db30d77efe228b7e117750d ] Some Chromebook BIOS' do not export an ACPI LPIT, which is how Linux finds the residency counter for CPU and SYSTEM low power states, that is exports in /sys/devices/system/cpu/cpuidle/*residency_us When these sysfs attributes are missing, check the debugfs attrubte from the pmc_core driver, which accesses the same counter value.

cpupower: Revert library ABI changes from commit ae2917093fb60bdc1ed3e

2020-02-11T12:35:24+00:00

commit 41ddb7e1f79693d904502ae9bea609837973eff8 upstream. Commit ae2917093fb6 ("tools/power/cpupower: Display boost frequency separately") modified the library function: struct cpufreq_available_frequencies *cpufreq_get_available_frequencies(unsigned int cpu) to struct cpufreq_frequencies *cpufreq_get_frequencies(const char *type, unsigned int cpu) This patch recovers the old API and implements the new functionality in a newly introduce method: struct cpufreq_boost_frequencies *cpufreq_get_available_frequencies(unsigned int cpu) This one should get merged into stable kernels back to 5.0 when the above had been introduced.

tools/power/x86/intel-speed-select: Ignore missing config level

2020-01-04T18:18:20+00:00

[ Upstream commit 20183ccd3e4d01d23b0a01fe9f3ee73fbae312fa ] It is possible that certain config levels are not available, even if the max level includes the level. There can be missing levels in some platforms. So ignore the level when called for information dump for all levels and fail if specifically ask for the missing level. Here the changes is to continue reading information about other levels even if we fail to get information for the current level. But use the "processed" flag to indicate the failure. When the "processed" flag is not set, don't dump information about that level. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko Signed-off-by: Sasha Levin
