tools/power/x86/intel-speed-select: Release v1.13

2022-09-15T18:16:06Z

Update version number. This version includes fixes for: - fix build failure when using gcc options -Wl,--as-needed - Fix warning for perf_cap.cpu may be uninitialized - Fix off by one check for MAX_DIE_PER_PACKAGE - Fix issue with use of get_physical_die_id instead of get_physical_die_id Optimizations: - Removed unused interfaces and functions - Better handle package, die, cpu combination by defining a struct and set at one place instead at each user level. New functional change: - Warn if turbo is disabled and SST turbo-freq feature is requested Signed-off-by: Srinivas Pandruvada

tools/power/x86/intel-speed-select: Optimize CPU initialization

2022-09-15T18:16:06Z

Optimize CPU initialization. Do cpu related initialization in one function, including setting the cpu present_cpumask, target_cpumask, and cpu_map and core_count arrays. Signed-off-by: Zhang Rui Signed-off-by: Srinivas Pandruvada

tools/power/x86/intel-speed-select: Utilize cpu_map to get physical id

2022-09-15T18:16:06Z

cpu_map already has the cpu package id, die id information. Thus there is no need to re-evaluating sysfs attributes or stored data file to get the package id and die id of a given CPU each time. In order to unitlize this, cpu_map needs to be created unconditionally. Signed-off-by: Zhang Rui Signed-off-by: Srinivas Pandruvada

tools/power/x86/intel-speed-select: Remove unused struct clos_config fields

2022-09-15T18:16:06Z

pkg_id/die_id can be retrieved from struct isst_id, remove the redundant clos_config->pkg_id/die_id fields. Signed-off-by: Zhang Rui Signed-off-by: Srinivas Pandruvada

tools/power/x86/intel-speed-select: Enforce isst_id value

2022-09-15T18:16:05Z

Enforce the pkg/die value in struct isst_id are either -1 or a valid value. This helps avoid inconsistent or redundant checks. Signed-off-by: Zhang Rui Signed-off-by: Srinivas Pandruvada

tools/power/x86/intel-speed-select: Do not export get_physical_id

2022-09-15T18:16:05Z

Now, all the get_physical_pkg/die/core_id() users are inside isst-config.c, so no need to export these APIs. Signed-off-by: Zhang Rui Signed-off-by: Srinivas Pandruvada

tools/power/x86/intel-speed-select: Introduce is_cpu_in_power_domain helper

2022-09-15T18:16:05Z

struct isst_id contains cpu, package and die info, and it can represent a specific SST power domain. Introduce is_cpu_in_power_domain() helper to identify if a cpu is in a specified power_domain. And cleanup the code to use the new helper. Signed-off-by: Zhang Rui Signed-off-by: Srinivas Pandruvada

tools/power/x86/intel-speed-select: Cleanup get_physical_id usage

2022-09-15T18:16:05Z

struct isst_id already contains package and die id information, thus there is no need to get the package and die id information, when struct isst_id is already available. Remove unneeded get_physical_package_id/get_physical_die_id usage. Signed-off-by: Zhang Rui Signed-off-by: Srinivas Pandruvada

tools/power/x86/intel-speed-select: Convert more function to use isst_id

2022-09-15T18:16:05Z

With pkg and die info added into struct isst_id, more functions can be converted to use struct isst_id as parameter. Signed-off-by: Zhang Rui Signed-off-by: Srinivas Pandruvada

tools/power/x86/intel-speed-select: Add pkg and die in isst_id

2022-09-15T18:16:05Z

Code uses pkg_id and die_id to refer to a specific power domain. The pkg/die information is already settled at start time. Adding package id and die id information into struct isst_id so that code does not need to retrieve them at runtime. More code cleanups can be done with the package/die info available.
