tools/power turbostat: fix ICX DRAM power numbers

2022-06-09T08:20:51Z

[ Upstream commit 6397b6418935773a34b533b3348b03f4ce3d7050 ] ICX (and its duplicates) require special hard-coded DRAM RAPL units, rather than using the generic RAPL energy units. Reported-by: Srinivas Pandruvada Signed-off-by: Len Brown Signed-off-by: Sasha Levin

tweewide: Fix most Shebang lines

2021-05-22T09:40:55Z

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

Revert "tools/power turbostat: adjust for temperature offset"

2021-05-14T07:50:05Z

commit b2b94be787bf47eedd5890a249f3318bf9f1f1d5 upstream. This reverts commit 6ff7cb371c4bea3dba03a56d774da925e78a5087. Apparently the TCC offset should not be used to adjust what temperature we show the user after all. (on most systems, TCC offset is 0, FWIW) Fixes: 6ff7cb371c4b Signed-off-by: Len Brown Signed-off-by: Greg Kroah-Hartman

tools/power turbostat: Fix offset overflow issue in index converting

2021-05-11T12:47:40Z

commit 13a779de4175df602366d129e41782ad7168cef0 upstream. The idx_to_offset() function returns type int (32-bit signed), but MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number. The end result is that it hits the if (offset < 0) check in update_msr_sum() which prevents the timer callback from updating the stat in the background when long durations are used. The similar issue exists in offset_to_idx() and update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.

tools/power/turbostat: Fix turbostat for AMD Zen CPUs

2021-05-11T12:47:33Z

commit 301b1d3a9104f4f3a8ab4171cf88d0f55d632b41 upstream. It was reported that on Zen+ system turbostat started exiting, which was tracked down to the MSR_PKG_ENERGY_STAT read failing because offset_to_idx wasn't returning a non-negative index. This patch combined the modification from Bingsong Si and Bas Nieuwenhuizen and addd the MSR to the index system as alternative for MSR_PKG_ENERGY_STATUS.

tools/power/x86/intel-speed-select: Increase string size

2021-05-11T12:47:20Z

[ Upstream commit 2e70b710f36c80b6e78cf32a5c30b46dbb72213c ] The current string size to print cpulist can accommodate upto 80 logical CPUs per package. But this limit is not enough. So increase the string size. Also prevent buffer overflow, if the string size reaches limit. Signed-off-by: Srinivas Pandruvada Signed-off-by: Hans de Goede Signed-off-by: Sasha Levin

tools/power/x86/intel-speed-select: Set higher of cpuinfo_max_freq or base_frequency

2021-02-07T14:37:13Z

[ Upstream commit bbaa2e95e23e74791dd75b90d5ad9aad535acc6e ] In some case when BIOS disabled turbo, cpufreq cpuinfo_max_freq can be lower than base_frequency at higher config level. So, in that case set scaling_min_freq to base_frequency.

tools/power/x86/intel-speed-select: Set scaling_max_freq to base_frequency

2021-02-07T14:37:13Z

[ Upstream commit f981dc171c04c6cf5a35c712543b231ebf805832 ] When BIOS disables turbo, The scaling_max_freq in cpufreq sysfs will be limited to config level 0 base frequency. But when user selects a higher config levels, this will result in higher base frequency. But since scaling_max_freq is still old base frequency, the performance will still be limited. So when the turbo is disabled and cpufreq base_frequency is higher than scaling_max_freq, update the scaling_max_freq to the base_frequency.
