2022-09-15tools/power/x86/intel-speed-select: Release v1.13Srinivas Pandruvada1-1/+1
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 <srinivas.pandruvada@linux.intel.com>
2022-09-15tools/power/x86/intel-speed-select: Optimize CPU initializationZhang Rui1-58/+38
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 <rui.zhang@intel.com> Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
2022-09-15tools/power/x86/intel-speed-select: Utilize cpu_map to get physical idZhang Rui1-11/+36
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 <rui.zhang@intel.com> Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

2022-09-15tools/power/x86/intel-speed-select: Introduce is_cpu_in_power_domain helperZhang Rui3-21/+25
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.

Code uses pkg_id and die_id to refer to a specific power domain. The pkg/die information is already settled at start time.

2022-09-15tools/power/x86/intel-speed-select: Introduce struct isst_idZhang Rui6-368/+396
SST control is power-domain based rather than cpu based, on all the systems including Sapphire Rapids and ealier. SST core APIs uses cpu id as parameter, and use the underlying pkg_id and die_id information to find a power domain, this is not straight forward and introduces obscure logics in the code. Introduce struct isst_id to represent a SST Power Domain. All core APIs are converted to use struct isst_id as parameter instead of using cpu id.

2022-04-13tools/power/x86/intel-speed-select: fix build failure when using -Wl,--as-neededHerton R. Krzesinski1-1/+1
Build of intel-speed-select will fail if you run: $ LDFLAGS="-Wl,--as-needed" /usr/bin/make V=1 ... gcc -O2 -Wall -g -D_GNU_SOURCE -Iinclude -I/usr/include/libnl3 -Wl,--as-needed -lnl-genl-3 -lnl-3 intel-speed-select-in.o -o intel-speed-select /usr/bin/ld: intel-speed-select-in.o: in function `handle_event': (...)/linux/tools/power/x86/intel-speed-select/hfi-events.c:189: undefined reference to `nlmsg_hdr' ... In this case the problem is that order when linking matters when using the flag -Wl,--as-needed, symbols not used at that point are discarded. So since intel-speed-select-in.o comes after, at that point the libraries/symbols are already discarded and then missing/undefined references are reported. To fix this, make sure we specify LDFLAGS after the object file. Acked-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Herton R.

$(or ...) is available since GNU Make 3.81, and useful to shorten the code in some places. Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A".

2021-12-24tools/power/x86/intel-speed-select: Update max frequencySrinivas Pandruvada1-0/+2
When BIOS disables turbo, the cpuinfo_max_freq will also be same as the power up base frequency. When SST-PP causes increase in base frequency the performance will be still limited to the old base frequency as the cpuinfo_max_freq will not be updated. In this case we need to update scaling_max frequency to the new base_frequency. This will result in setting updated max performance limit in the Pstate driver. So performance will not be limited to the old base frequency.
