2015-02-09tools/power turbostat: Skip printing disabled package C-statesLen Brown
Replaced previously open-coded Package C-state Limit decoding with table-driven decoding. In doing so, updated to match January 2015 "Intel(R) 64 and IA-23 Architectures Software Developer's Manual". In the past, turbostat would print package C-state residency columns for all package states supported by the model's architecture, even though a particular SKU may not support them, or they may be disabled by the BIOS. Now turbostat will skip printing colunns if MSRs indicate that they are not enabled. eg. many SKUs don't support PC7, and so that column will no longer be printed.

2015-02-09tools/power turbostat: relax dependency on APERF_MSRLen Brown
While turbostat is significantly less useful on systems with no APERF_MSR, it seems more friendly to run on such systems and report what we can, rather than refusing to run. Update man page to reflect recent changes. Signed-off-by: Len Brown <len.brown@intel.com>
2015-02-09tools/power turbostat: relax dependency on invariant TSCLen Brown
Turbostat can be useful on systems that do not support invariant TSC, so allow it to run on those systgems. All arithmetic in turbostat using the TSC value is per-processsor, so it does not depend on the TSC values being in sync acrosss processors. Turbostat uses gettimeofday() for the measurement interval rather than using the TSC directly, so that key metric is also immune from variable TSC. Turbostat prints a TSC sanity check column: TSC_MHz = TSC_delta/interval If this column is constant and is close to the processor base frequency, then the TSC is behaving properly. The other key turbostat columns are calculated this way: Avg_Mhz = APERF_delta/interval %Busy = MPERF_delta/TSC_delta Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/interval Tested on Core2 and Core2-Xeon, and so this patch includes a few other changes to remove the assumption that target systems are Nehalem and newer.

2015-02-09tools/power turbostat: decode MSR_*_PERF_LIMIT_REASONSLen Brown
The Processor generation code-named Haswell added MSR_{CORE | GFX | RING}_PERF_LIMIT_REASONS to explain when and how the processor limits frequency. turbostat -v will now decode these bits. Each MSR has an "Active" set of bits which describe current conditions, and a "Logged" set of bits, which describe what has happened since last cleared. Turbostat currently doesn't clear the log bits. Signed-off-by: Len Brown <len.brown@intel.com>
2015-02-09tools/power turbostat: relax dependency on root permissionLen Brown
For turbostat to run as non-root, it needs to permissions: 1. read access to /dev/cpu/*/msr via standard user/group/world file permissions 2. CAP_SYS_RAWIO eg. # setcap cap_sys_rawio=ep turbostat Yes, running as root still works. Signed-off-by: Len Brown <len.brown@intel.com>

2014-12-14Revert "tools: cpupower: fix return checks for sysfs_get_idlestate_count()"Prarit Bhargava
This reverts commit 16b7c275c055cc36218404b5d147be7f76575087. My previous commit 16b7c275c055 ("tools: cpupower: fix return checks for sysfs_get_idlestate_count()") was not correct. After looking at the changelog for cpupower I noticed that Thomas had changed the return of sysfs_get_idlestate_count() to an unsigned int to simplify the code. The problem is really that both he (in his original change) and I (in my new change) missed the obvious that sysfs_get_idlestate_count() can't return -ENODEV. It should just return 0 for "no c-states". Fixes: 16b7c275c055 (tools: cpupower: fix return checks for ...) Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Rafael J.

2014-12-05tools: cpupower: fix return checks for sysfs_get_idlestate_count()Prarit Bhargava
Red Hat and Fedora use a bug reporting tool that gathers data about "broken" systems called sosreport. Among other things, it includes the output of 'cpupower idle-info'. Executing 'cpupower idle-info' on a system that has cpuidle disabled via 'cpuidle.off=1' results in a 300 second hang in the cpupower application. ie) [root@intel-brickland-05]# cpupower idle-info Could not determine cpuidle driver Analyzing CPU 0: Number of idle states: -19 [hang] The problem is that the cpupower code only checks for a zero return from sysfs_get_idlestate_count(). The function can return -ENODEV (-19) as above. This patch fixes callers to sysfs_get_idlestate_count() to check the right return values.

This patch uses abstract file IO and acpi_log_error() APIs to enhance cm_get_file_size() so that applications that invoke this API could have portability improved. With actual references added to abstract file IO and acpi_log_error(), the applications need to link oslibcfs.o, utdebug.o, utexcep.o, utmath.o, utprint.o and utxferror.o.

acpi_os_printf() to improve portability This patch enhances ACPI_USAGE_xxx/ACPI_OPTION macros to use portable acpi_os_printf() so that usage functions for applications no longer rely on the printf() API. To use acpi_os_printf() exported by osunixxf.c as a replacement of printf(), applications need to initialize acpi_gbl_output_file to stdout and initialize acpi_gbl_db_output_flags to ACPI_DB_CONSOLE_OUTPUT. The latter is automatically done by ACPI_INIT_GLOBAL(), applications need to link utglobal.o to utilize this mechanism. For GCC, assigning stdout to acpi_gbl_output_file using ACPI_INIT_GLOBAL() is not possible as stdout is not a constant in GCC environment. As an alternative solution, stdout assignment has been put into acpi_os_initialize(). Thus acpi_os_initialize() need to be invoked very early by the applications to initialize the default output of acpi_os_printf() to keep behavior consistency. acpidump has already invoked acpi_os_initialize() in this way.

2014-07-08ACPICA: Utilities: Add formatted printing APIsLv Zheng
This patch introduces formatted printing APIs to handle ACPICA specific formatted print requirements. Currently only specific OSPMs will use this customized printing support, Linux kernel doesn't use these APIs at this time. It will be enabled for Linux kernel resident ACPICA after being well tested. So currently this patch is a no-op. The specific formatted printing APIs are useful to ACPICA as: 1. Some portable applications do not link standard C library, so they cannot use standard formatted print APIs directly. 2. Platform specific printing format may differ and thus not portable, for example, u64 is %ull for Linux kernel and is %uI64 for some MSVC versions. 3. Platform specific printing format may conflict with ACPICA's usages while it is not possible for ACPICA developers to test their code for all platforms. For example, developers may generate %pRxxx while Linux kernel treats %pR as structured resource printing and decodes variable argument as a "struct resource" pointer. This patch solves above issues by introducing the new APIs. Note that users of such APIs are not introduced in this patch. Users of acpi_os_file_vprintf()/acpi_ut_file_printf() need to invoke acpi_os_initialize(), this should be taken care by the further patches where such users are introduced. Lv Zheng.

This patch cleans up such specific implementation by linking acpidump to osunixxf.c/oswinxf.c.

2014-07-08ACPICA: Utilities: Cleanup DEFINE_ACPI_GLOBALS by moving ↵Lv Zheng
acpi_ut_init_global() from utglobal.c to utinit.c The utglobal.c is used to define and initialize global variables. It makes sense if just adding utglobal.o to applications that are using such variables. But acpi_ut_init_globals() is preventing us from doing so as this initialization function references other components' initializations code, which leads to the requirement that many files should also get linked if one wants to link utglobal.o. It is possible to just move acpi_ut_init_global() to utinit.c for applications that require this function to link. By linking utglobal.o, we can stop defining DEFINE_ACPI_GLOBALS for applications (currently only acpidump is affected). Lv Zheng.
