2021-06-18tools/power/x86/intel-speed-select: v1.10 releaseSrinivas Pandruvada1-1/+1
This release adds following change: - Fix reporting of memory frequency Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2021-06-18tools/power/x86/intel-speed-select: Fix uncore memory frequency displaySrinivas Pandruvada1-0/+16
The uncore memory frequency value from the mailbox command CONFIG_TDP_GET_MEM_FREQ needs to be scaled based on the platform for display. There is no single constant multiplier. This change introduces CPU model specific memory frequency multiplier. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

2021-04-07tools/power/x86/intel-speed-select: Add options to force onlineSrinivas Pandruvada1-2/+21
It is possible that users manually offlined CPUs via sysfs interface and then started this utility. In this case we will not be able to get package and die id of the those CPUs. So add an option to force online if required for some commands. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

base_frequency In some case when BIOS disabled turbo, cpufreq cpuinfo_max_freq can be lower than base_frequency at higher config level. So, in that case set scaling_min_freq to base_frequency.

2021-01-04tools/power/x86/intel-speed-select: Set scaling_max_freq to base_frequencySrinivas Pandruvada1-0/+21
When BIOS disables turbo, The scaling_max_freq in cpufreq sysfs will be limited to config level 0 base frequency. But when user selects a higher config levels, this will result in higher base frequency. But since scaling_max_freq is still old base frequency, the performance will still be limited. So when the turbo is disabled and cpufreq base_frequency is higher than scaling_max_freq, update the scaling_max_freq to the base_frequency.

2020-12-08tools/power/x86/intel-speed-select: Account for missing sysfs for die_idSrinivas Pandruvada1-1/+5
Some older kernels will not have support to get CPU die_id from the sysfs. This requires several back ports. But the tool depends on getting die_id to match to correct CPU. Relax this restriction and use die_id as 0 when die_id is missing. This is not a problem as we don't have any multi-die processors with Intel SST support. This helps in running this tool on older kernels with just Intel SST drivers back ported.

The reported base-freq high-priority-cpu-list was potentially omitting some cpus, due to incorrectly using a logical core count to constrain the size of a physical punit core ID mask.

2020-05-22tools/power/x86/intel-speed-select: Fix invalid core maskSrinivas Pandruvada1-1/+1
The core mask display is wrong in some cases. This is showing more cpus than the mask has. This is because mask is 64 bit but it used with BIT() macro to get the presence of CPU which doesn't support unsigned long long. Added a new macro for BIT_ULL and use that to get the presence of a CPU. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

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.

2020-03-20tools/power/x86/intel-speed-select: Store topology informationSrinivas Pandruvada1-11/+132
Once the CPU is offline, the topology information (core-id, package-id, die-id) is not accessible via sysfs. 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.
