2025-06-08tools/power turbostat: Avoid probing the same perf countersZhang Rui
For the RAPL package energy status counter, Intel and AMD share the same perf_subsys and perf_name, but with different MSR addresses. Both rapl_counter_arch_infos[0] and rapl_counter_arch_infos[1] are introduced to describe this counter for different Vendors. As a result, the perf counter is probed twice, and causes a failure in in get_rapl_counters() because expected_read_size and actual_read_size don't match. Fix the problem by skipping the already probed counter. Note, this is not a perfect fix. For example, if different vendors/platforms use the same MSR value for different purpose, the code can be fooled when it probes a rapl_counter_arch_infos[] entry that does not belong to the running Vendor/Platform. In a long run, better to put rapl_counter_arch_infos[] into the platform_features so that this becomes Vendor/Platform specific.

2025-06-08tools/power turbostat: Allow probing RAPL with platform_features->rapl_msrs ↵Zhang Rui
cleared platform_features->rapl_msrs describes the RAPL MSRs supported. While RAPL Perf counters can be exposed from different kernel backend drivers, e.g. RAPL MSR I/F driver, or RAPL TPMI I/F driver. Thus, turbostat should first blindly probe all the available RAPL Perf counters, and falls back to the RAPL MSR counters if they are listed in platform_features->rapl_msrs. With this, platforms that don't have RAPL MSRs can clear the platform_features->rapl_msrs bits and use RAPL Perf counters only.

Introduce wrapper function add_rapl_msr_counter() at the same time to add extra check for Zero return value for specified RAPL counters. No functional change intended.

2025-06-08tools/power turbostat: Fix AMD package-energy reportingGautham R. Shenoy
commit 05a2f07db888 ("tools/power turbostat: read RAPL counters via perf") that adds support to read RAPL counters via perf defines the notion of a RAPL domain_id which is set to physical_core_id on platforms which support per_core_rapl counters (Eg: AMD processors Family 17h onwards) and is set to the physical_package_id on all the other platforms. However, the physical_core_id is only unique within a package and on platforms with multiple packages more than one core can have the same physical_core_id and thus the same domain_id. (For eg, the first cores of each package have the physical_core_id = 0). This results in all these cores with the same physical_core_id using the same entry in the rapl_counter_info_perdomain[]. Since rapl_perf_init() skips the perf-initialization for cores whose domain_ids have already been visited, cores that have the same physical_core_id always read the perf file corresponding to the physical_core_id of the first package and thus the package-energy is incorrectly reported to be the same value for different packages. Note: This issue only arises when RAPL counters are read via perf and not when they are read via MSRs since in the latter case the MSRs are read separately on each core. Fix this issue by associating each CPU with rapl_core_id which is unique across all the packages in the system.

2025-06-08tools/power turbostat: Add Android support for MSR device handlingKaushlendra Kumar
It uses /dev/msrN device paths on Android instead of /dev/cpu/N/msr, updates error messages and permission checks to reflect the Android device path, and wraps platform-specific code with #if defined(ANDROID) to ensure correct behavior on both Android and non-Android systems.
