| * | tools/power/x86/intel-speed-select: Add display for enabled cpus countSrinivas Pandruvada2020-03-201-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In addition to total CPU count also display "enabled-cpu-count" for perf-profile info command. This will show number of CPUs in the "enable-cpu-mask". For example: perf-profile-level-4 cpu-count:32 enable-cpu-count:16 enable-cpu-mask:e42d0000,e42d0000 Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

| * | tools/power/x86/intel-speed-select: Improve CLX commandsSrinivas Pandruvada2020-03-201-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CLX doesn't have capability to change the feature in the hardware, but this acts as "--auto | -a" option. So even if user didn't specify the option, use this as --auto | -a to set cpufreq scaling frequency limits. Also remove perror with debug_printf as they don't bring any value.

| * | tools/power/x86/intel-speed-select: Kernel interface error handlingSrinivas Pandruvada2020-03-201-6/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Treat a case when mailbox/mmio command can't be handled by the kernel drivers when the module is removed or send a command which no driver can handle. In this case ENOTTY result is returned, so print error. Also when the isst_if_mmio module is removed, we can't send CLOS message messages via Mailbox on non SKX based platforms. When this module is removed, isst_platform_info.mmio_supported is set to 0. So it can't be used as a condition to send via mailbox. Here replace check for Skylake based platform to send via mailbox, other platforms can't use mailbox in lieu of MMIO.

So when user selects a config level more than base config 0 and offlined CPUs to match the config level, to return to base config he has to manually online CPUs before. Without this CPUs information mapping from Punit CPU numbering will lot work as it needs atlest package id for each CPU. To avoid this additional steps store the topology information in a file , which is created on the very first run after boot. Since system boots in base config and all CPUs are online, we can get information about every CPU. Once any of the APIs like get_physical_package_id(), get_physical_core_id() or get_physical_die_id() fails to read from sysfs, read from the stored mapping file. This mapping file is stored in /tmp file system. so on every boot it is recreated to make sure that any new CPUs are added to the system before boot are taken into account. But don't use the stored physical device id when trying to get information for CPU to send message in for_each_online_package_in_set(). Here use the real value from syfs and in case fails try the next CPU.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Manpage of cpupower is listing wrong sub-commands in "See Also" section. The option for cpupower-idle(1) should actually be cpupower-idle-info(1) and cpupower-idle-set(1). This patch corrects this anomaly.

Update KVM's VMX selftest and turbostat accordingly. Keep the full name in turbostat's output to avoid breaking someone's workflow, e.g. if a script is looking for the full name. While using the renamed defines is by no means necessary, do the sync now to avoid leaving a landmine that will get stepped on the next time msr-index.h needs to be refreshed for some other reason.
