x86/msr-index: Cleanup bit defines

2019-05-14T17:17:10+00:00

commit d8eabc37310a92df40d07c5a8afc53cebf996716 upstream

Greg pointed out that speculation related bit defines are using (1 << N)
format instead of BIT(N). Aside of that (1 << N) is wrong as it should use
1UL at least.

Clean it up.

tools/power turbostat: return the exit status of a command

2019-04-20T07:16:50+00:00

[ Upstream commit 2a95496634a017c19641f26f00907af75b962f01 ]

turbostat failed to return a non-zero exit status even though the
supplied command (turbostat ) failed.  Currently when turbostat
forks a command it returns zero instead of the actual exit status of the
command.  Modify the code to return the exit status.

Merge tag 'acpi-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

2018-12-25T22:21:18+00:00

Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to the 20181213 upstream
  revision, make it possible to build the ACPI subsystem without PCI
  support, and a new OEM _OSI string, add a new device support to the
  ACPI driver for AMD SoCs and fix PM handling in the ACPI driver for
  Intel SoCs, fix the SPCR table handling and do some assorted fixes and
  cleanups.

  Specifics:

   - Update the ACPICA code in the kernel to the 20181213 upstream
     revision including:
      * New Windows _OSI strings (Bob Moore, Jung-uk Kim).
      * Buffers-to-string conversions update (Bob Moore).
      * Removal of support for expressions in package elements (Bob
        Moore).
      * New option to display method/object evaluation in debug output
        (Bob Moore).
      * Compiler improvements (Bob Moore, Erik Schmauss).
      * Minor debugger fix (Erik Schmauss).
      * Disassembler improvement (Erik Schmauss).
      * Assorted cleanups (Bob Moore, Colin Ian King, Erik Schmauss).

   - Add support for a new OEM _OSI string to indicate special handling
     of secondary graphics adapters on some systems (Alex Hung).

   - Make it possible to build the ACPI subystem without PCI support
     (Sinan Kaya).

   - Make the SPCR table handling regard baud rate 0 in accordance with
     the specification of it and make the DSDT override code support
     DSDT code names generated by recent ACPICA (Andy Shevchenko, Wang
     Dongsheng, Nathan Chancellor).

   - Add clock frequency for Hisilicon Hip08 SPI controller to the ACPI
     driver for AMD SoCs (APD) (Jay Fang).

   - Fix the PM handling during device init in the ACPI driver for Intel
     SoCs (LPSS) (Hans de Goede).

   - Avoid double panic()s by clearing the APEI GHES block_status before
     panic() (Lenny Szubowicz).

   - Clean up a function invocation in the ACPI core and get rid of some
     code duplication by using the DEFINE_SHOW_ATTRIBUTE macro in the
     APEI support code (Alexey Dobriyan, Yangtao Li)"

tools/power/x86/intel_pstate_tracer: Fix non root execution for post processing a trace file

2018-12-18T09:44:17+00:00

This script is supposed to be allowed to run with regular user
privileges if a previously captured trace is being post processed.

Commit fbe313884d7d (tools/power/x86/intel_pstate_tracer: Free the
trace buffer memory) introduced a bug that breaks that option.

Commit 35459105deb2 (tools/power/x86/intel_pstate_tracer: Add
optional setting of trace buffer memory allocation) moved the code
but kept the bug.

This patch fixes the issue.

tools/power turbostat: consolidate duplicate model numbers

2018-12-15T01:08:55+00:00

Often a new processor gets a new model number, but from a turbostat
point of view, it is the same as a previous model.  Support duplicates
with 1-line updates, rather than error-prone scattering of model #'s.
