git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx Pull SPDX updates from Greg KH: "Here are three SPDX patches for 5.7-rc1. One fixes up the SPDX tag for a single driver, while the other two go through the tree and add SPDX tags for all of the .gitignore files as needed. Nothing too complex, but you will get a merge conflict with your current tree, that should be trivial to handle (one file modified by two things, one file deleted.) All three of these have been in linux-next for a while, with no reported issues other than the merge conflict" * tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: ASoC: MT6660: make spdxcheck.py happy .gitignore: add SPDX License Identifier .gitignore: remove too obvious comments

2020-03-20tools/power/x86/intel-speed-select: Avoid duplicate Package strings for jsonSrinivas Pandruvada
For platforms where multiple packages/die, this makes "Package-" key duplicate. To make unique, add die and cpu id to key name. So "Package-0" key name will change to "Package-0-die-x:cpu-x". For example: $sudo ./intel-speed-select -f json perf-profile info Intel(R) Speed Select Technology Executing on CPU model:106[0x6a] { "package-0:die-0:cpu-0": { "perf-profile-level-0": { "cpu-count": "32", "enable-cpu-count": "32", ... ... "package-1:die-0:cpu-16": { "perf-profile-level-0": { "cpu-count": "32", "enable-cpu-count": "32", "enable-cpu-mask": "ffff0000,ffff0000", ... ... For non json format, there is no change. Here when print_package_info() is called, it will return the level to print for other information. This level is used formatting. Also in some function duplicate code was there to print package,die and CPU information. Replace all that code with a call to print_package_info().

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 Pandruvada
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.

For the command "intel-speed-select perf-profile info": There are two instances of “speed-select-turbo-freq” underneath “perf-profile-level-0” for each package. When we load the output into python with json.load(), the second instance overwrites the first. Result is that we can only access: "speed-select-turbo-freq": { "bucket-0": { "high-priority-cores-count": "2", "high-priority-max-frequency(MHz)": "3000", "high-priority-max-avx2-frequency(MHz)": "2800", "high-priority-max-avx512-frequency(MHz)": "2600" }, Because it is a duplicate of "speed-select-turbo-freq": "disabled" Same is true for "speed-select-base-freq".
