* turbostat: Increase output buffer size to accommodate C8-C10Josh Triplett2013-06-131-1/+1
| | | | | | | | | | | | | | | On platforms with C8-C10 support, the additional C-states cause turbostat to overrun its output buffer of 128 bytes per CPU. Increase this to 256 bytes per CPU. [ As a bugfix, this should go into 3.10; however, since the C8-C10 support didn't go in until after 3.9, this need not go into any stable kernel. ] Signed-off-by: Josh Triplett <josh@joshtriplett.org> Cc: Len Brown <len.brown@intel.com> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The turbostat Makefile is pretty simple, its output is placed in the same directory as the source, the install rule has no concept of a prefix or sysroot, and you can set CC to use a specific compiler but not use the more familiar CROSS_COMPILE. By making a few minor changes these limitations are removed while leaving the default behavior matching what it used to be.

Intel's Sandy Bridge and Ivy Bridge processor generations support RAPL (Run-Time-Average-Power-Limiting). Per the Intel SDM (Intel® 64 and IA-32 Architectures Software Developer Manual) RAPL provides hardware energy counters and power control MSRs (Model Specific Registers). RAPL MSRs are designed primarily as a method to implement power capping. However, they are useful for monitoring system power whether or not power capping is used. In addition, Turbostat now shows temperature from DTS (Digital Thermal Sensor) and PTM (Package Thermal Monitor) hardware, if present. As before, turbostat reads MSRs, and never writes MSRs. New columns are present in turbostat output: The Pkg_W column shows Watts for each package (socket) in the system. On multi-socket systems, the system summary on the 1st row shows the sum for all sockets together. The Cor_W column shows Watts due to processors cores. Note that Core_W is included in Pkg_W. The optional GFX_W column shows Watts due to the graphics "un-core". Note that GFX_W is included in Pkg_W. The optional RAM_W column on server processors shows Watts due to DRAM DIMMS. As DRAM DIMMs are outside the processor package, RAM_W is not included in Pkg_W. The optional PKG_% and RAM_% columns on server processors shows the % of time in the measurement interval that RAPL power limiting is in effect on the package and on DRAM. Note that the RAPL energy counters have some limitations. First, hardware updates the counters about once every milli-second. This is fine for typical turbostat measurement intervals > 1 sec. However, when turbostat is used to measure events that approach 1ms, the counters are less useful. Second, the 32-bit energy counters are subject to wrapping. For example, a counter incrementing 15 micro-Joule units on a 130 Watt TDP server processor could (in theory) roll over in about 9 minutes. Turbostat detects and handles up to 1 counter overflow per measurement interval. But when the measurement interval exceeds the guaranteed counter range, we can't detect if more than 1 overflow occured. So in this case turbostat indicates that the results are in question by replacing the fractional part of the Watts in the output with "**": Pkg_W Cor_W GFX_W 3** 0** 0** Third, the RAPL counters are energy (Joule) counters -- they sum up weighted events in the package to estimate energy consumed. They are not analong power (Watt) meters. In practice, they tend to under-count because they don't cover every possible use of energy in the package. The accuracy of the RAPL counters will vary between product generations, and between SKU's in the same product generation, and with temperature. turbostat's -v (verbose) option now displays more power and thermal configuration information -- as shown on the turbostat.8 manual page. For example, it now displays the Package and DRAM Thermal Design Power (TDP): cpu0: MSR_PKG_POWER_INFO: 0x2f064001980410 (130 W TDP, RAPL 51 - 200 W, 0.045898 sec.) cpu0: MSR_DRAM_POWER_INFO,: 0x28025800780118 (35 W TDP, RAPL 15 - 75 W, 0.039062 sec.) cpu8: MSR_PKG_POWER_INFO: 0x2f064001980410 (130 W TDP, RAPL 51 - 200 W, 0.045898 sec.) cpu8: MSR_DRAM_POWER_INFO,: 0x28025800780118 (35 W TDP, RAPL 15 - 75 W, 0.039062 sec.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turbostat assumed if it can't migrate to a CPU, then the CPU must have gone off-line and turbostat should re-initialize with the new topology. But if turbostat can not migrate because it is restricted by a cpuset, then it will fail to migrate even after re-initialization, resulting in an infinite loop. Spit out a warning when we can't migrate and endure only 2 re-initialize cycles in a row before giving up and exiting. Signed-off-by: Len Brown <len.brown@intel.com>

* | cpupower tools: Fix warning and a bug with the cpu package countPalmer Cox2012-11-271-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pkgs member of cpupower_topology is being used as the number of cpu packages. As the comment in get_cpu_topology notes, the package ids are not guaranteed to be contiguous. So, simply setting pkgs to the value of the highest physical_package_id doesn't actually provide a count of the number of cpu packages. Instead, calculate pkgs by setting it to the number of distinct physical_packge_id values which is pretty easy to do after the core_info structs are sorted. Calculating pkgs this way also has the nice benefit of getting rid of a sign comparison warning that GCC 4.6 was reporting.

This member was then being malloced using the size of the parent cpupower_topology * the number of cpus. This works because cpu_info is smaller than cpupower_topology. However, there is no guarantee that will always be the case. Making cpu_info its own top level structure (named cpuid_core_info) allows for mallocing the actual size of this structure. This also lets us get rid of a redefinition of the structure in topology.c with slightly different field names.

The second one fixes make tar-pkg so that unpacking the tarball does not replace the /lib -> /usr/lib symlink on recent Fedora releases." * 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kbuild: Fix gcc -x syntax kbuild: Do not package /boot and /lib in make tar-pkg
| * kbuild: Fix gcc -x syntaxJean Delvare2012-10-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The -M option dumps the specified 64-bit MSR with every sample. Previously it was output at the end of each line. However, with the v2 style of printing, the lines are now staggered, making MSR output hard to read. So move the MSR output column to the left where things are aligned. Signed-off-by: Len Brown <len.brown@intel.com>
| | | * tools/power turbostat: print more turbo-limit informationLen Brown2012-09-261-2/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "turbo-limit" is the maximum opportunistic processor speed, assuming no electrical or thermal constraints. For a given processor, the turbo-limit varies, depending on the number of active cores. Generally, there is more opportunity when fewer cores are active. Under the "-v" verbose option, turbostat would print the turbo-limits for the four cases of 1 to 4 cores active. Expand that capability to cover the cases of turbo opportunities with up to 16 cores active. Note that not all hardware platforms supply this information, and that sometimes a valid limit may be specified for a core which is not actually present.
