2022-07-28tools/power turbostat: do not decode ACC for ICX and SPRArtem Bityutskiy
The ACC (automatic C-state conversion) feature was available on Sky Lake and Cascade Lake Xeons (SKX and CLX), but it is not available on Ice Lake and Sapphire Rapids Xeons (ICX and SPR). Therefore, stop decoding it for ICX and SPR. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2022-07-28tools/power turbostat: fix SPR PC6 limitsArtem Bityutskiy
Sapphire Rapids Xeon (SPR) supports 2 flavors of PC6 - PC6N (non-retention) and PC6R (retention). Before this patch we used ICX package C-state limits, which was wrong, because ICX has only one PC6 flavor. With this patch, we use SKX PC6 limits for SPR, because they are the same.

It would be handy to have cmdline in turbostat output. For example, according to the turbostat output, there are no C-states requested. In this case the user is very curious if something like intel_idle.max_cstate=0 was used, or may be idle=none too. It is also curious whether things like intel_pstate=nohwp were used.

This gives the ability to reprint the header every N iterations, so you can ensure that a scrolling display always has the header visible somewhere on the screen. Signed-off-by: Zephaniah E. Loss-Cutler-Hull <zephaniah@gmail.com> Signed-off-by: Len Brown <len.brown@intel.com>
2022-04-16tools/power turbostat: Allow -e for all names.Zephaniah E. Loss-Cutler-Hull
Currently, there are a number of variables which are displayed by default, enabled with -e all, and listed by --list, but which you can not give to --enable/-e. So you can enable CPU0c1 (in the bic array), but you can't enable C1 or C1% (not in the bic array, but exists in sysfs). This runs counter to both the documentation and user expectations, and it's just not very user friendly. As such, the mechanism used by --hide has been duplicated, and is now also used by --enable, so we can handle unknown names gracefully. Note: One impact of this is that truly unknown fields given to --enable will no longer generate errors, they will be silently ignored, as --hide does. Signed-off-by: Zephaniah E.

2022-04-13tools/power/x86/intel-speed-select: fix build failure when using -Wl,--as-neededHerton R. Krzesinski
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.

Before this patch: turbostat does not recognize value "3" on Ice Lake Xeon (ICX) and Sapphire Rapids Xeon (SPR), treats it as "unknown", and does not display any package C-states in the results table.
