| * kbuild: use $(abspath ...) instead of $(shell cd ... && /bin/pwd)Masahiro Yamada2017-09-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kbuild conventionally uses $(shell cd ... && /bin/pwd) idiom to get the absolute path of the directory because GNU Make 3.80, the minimal supported version at that time, did not support $(abspath ...) or $(realpath ...). Commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81") dropped the GNU Make 3.80 support, so we are now allowed to use those make-builtin helpers. This conversion will provide better portability without relying on the pwd command or its location /bin/pwd. I am intentionally using $(realpath ...) instead $(abspath ...) in some places. The difference between the two is $(realpath ...) returns an empty string if the given path does not exist. It is convenient in places where we need to error-out if the makefile fails to create an output directory.

| * | ACPICA: acpidump: Add DSDT/FACS instance support for Linux and EFILv Zheng2017-08-031-32/+73

And for FACS, it's meaningful to dump both of them as they are used to support different suspend protocols. While: 1. on Linux, only 1 instance is supported for DSDT/FACS; and 2. on EFI, the code in osl_get_table() is buggy with special table instances, causing endless file dump for such tables (reported by Shao Ming in link #2). This patch adds DSDT/FACS instance support for Linux/EFI acpidump. Fixed by Lv Zheng.

Otherwise, MSVC complains: acpidump.lib(utstrtoul64.obj) : error LNK2001: unresolved external symbol __allmul acpidump.lib(uthex.obj) : error LNK2001: unresolved external symbol __aullshr Note: 1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have different math64 supports. 2. Support of gcc math64 is not included in this patch. 3. Support of EDK2 arch independent math64 is done via linking to base_lib. This patch fixes this issue. Reported by Shao Ming, fixed by Lv Zheng. For Linux kernel, this patch is a functional no-op.

On top of that, an additional ACPICA change from Kees (which also is upstream already) switches all of the definitions of function pointer structures in ACPICA to use designated initializers so as to make the structure layout randomization GCC plugin work with it.

Hardware consults EPB when it makes internal decisions balancing energy-saving vs performance. For example, should HW quickly or slowly transition into and out of power-saving idles states? Should HW quickly or slowly ramp frequency up or down in response to demand in the turbo-frequency range? Depending on the processor, EPB may have package, core, or CPU thread scope. As such, the only general policy is to write the same value to EPB on every CPU in the system. Recent platforms add support for Hardware Performance States (HWP). HWP effectively extends hardware frequency control from the opportunistic turbo-frequency range to control the entire range of available processor frequencies. Just as turbo-mode used EPB, HWP can use EPB to help decicde how quickly to ramp frequency and voltage up and down in response to changing demand. Indeed, BDX and BDX-DE, the first processors to support HWP, use EPB for this purpose. Starting in SKL, HWP no longer looks to EPB for influence. Instead, it looks in a new MSR specifically for this purpose: IA32_HWP_REQUEST.Energy_Performance_Preference (HWP.EPP). HWP.EPP is like EPB, except that it is specific to HWP-mode frequency selection. Also, HWP.EPP is defined to have per CPU-thread scope. Starting in SKX, IA32_HWP_REQUEST is augmented by IA32_HWP_REQUEST_PKG -- which has the same function, but is defined to have package-wide scope. A new bit in IA32_HWP_REQUEST determines if it over-rides the IA32_HWP_REQUEST_PKG or not. Note that HWP-mode can be enabled in several ways. The "in-band" method is for HWP to be exposed in CPUID, and for the Linux intel_pstate driver to recognized that, and thus enable HWP. In this case, starting in Linux 4.10, intel_pstate exports cpufreq sysfs attribute "energy_performance_preference" which can be used to manage HWP.EPP. This interface can be used to set HWP.EPP to these values: 0 performance 128 balance_performance (default) 192 balance_power 255 power Here, x86_energy_performance_policy is updated to use idential strings and values as intel_pstate. But HWP-mode may also be enabled by firmware before the OS boots, and the OS may not be aware of HWP. In this case, intel_pstate is not available to provide sysfs attributes, and x86_energy_perf_policy or a similar utility is invaluable for managing HWP.EPP, for this utility works the same, no matter if cpufreq is enabled or not.

For any run as root the specific testname subdirectory will not allow any subsequent file saves by a regular user.

Turbostat detect that case and simply prints c1 = 0.00% But that check neglected to account for systems where the TSC crystal clock domain and the MPERF BCLK domain are differ by a small amount. That allowed very small negative c1 numbers to escape this check and be printed as huge positve numbers. This code begs for a bit of cleanup, but this patch is the minimal change to fix the issue.

Add an error message showing that exec failed: sudo turbostat sleeeep 4 ... turbostat: exec sleeeep: No such file or directory ... Note that the parent will still print out the statistics, because it can't tell the difference between the failed exec and a command that is purposefully returning the same status.

This was because we process "--hide" before we probe for those columns. hack --hide to remember deferred hide requests, and apply them when sysfs is probed. "--hide sysfs" is still available as short-hand to refer to the entire group of counters. The down-side of this change is that we no longer error check for bogus --hide column names.
