tools/power/acpi: fix compilation error

2020-02-14T21:34:15+00:00

commit 1985f8c7f9a42a651a9750d6fcadc74336d182df upstream.

If we compile tools/acpi target in the top source directory, we'd get a
compilation error showing as bellow:

	# make tools/acpi
	  DESCEND  power/acpi
	  DESCEND  tools/acpidbg
	  CC       tools/acpidbg/acpidbg.o
	Assembler messages:

cpupower: Revert library ABI changes from commit ae2917093fb60bdc1ed3e

2020-02-11T12:35:24+00:00

commit 41ddb7e1f79693d904502ae9bea609837973eff8 upstream.

Commit ae2917093fb6 ("tools/power/cpupower: Display boost frequency
separately") modified the library function:

struct cpufreq_available_frequencies
*cpufreq_get_available_frequencies(unsigned int cpu)

to
struct cpufreq_frequencies
*cpufreq_get_frequencies(const char *type, unsigned int cpu)

This patch recovers the old API and implements the new functionality
in a newly introduce method:
struct cpufreq_boost_frequencies
*cpufreq_get_available_frequencies(unsigned int cpu)

This one should get merged into stable kernels back to 5.0 when
the above had been introduced.

tools/power/x86/intel-speed-select: Ignore missing config level

2020-01-04T18:18:20+00:00

[ Upstream commit 20183ccd3e4d01d23b0a01fe9f3ee73fbae312fa ]

It is possible that certain config levels are not available, even
if the max level includes the level. There can be missing levels in
some platforms. So ignore the level when called for information dump
for all levels and fail if specifically ask for the missing level.

Here the changes is to continue reading information about other levels
even if we fail to get information for the current level. But use the
"processed" flag to indicate the failure. When the "processed" flag is
not set, don't dump information about that level.

tools/power/cpupower: Fix initializer override in hsw_ext_cstates

2019-12-31T15:43:26+00:00

[ Upstream commit 7e5705c635ecfccde559ebbbe1eaf05b5cc60529 ]

When building cpupower with clang, the following warning appears:

This appears to be a copy and paste or merge mistake because the name
and id fields both have PC9 in them, not PC2. Remove the second
assignment to fix the warning.

tools/power/x86/intel-speed-select: Fix perf-profile command output

2019-09-19T11:51:29+00:00

commit "c016ae8f9fa04d361efc8629de49ad3af12b5262
"tools/power/x86/intel-speed-select: Output success/failed for command
output" introduced a regression in perf-profile outputs. With this
the result field is changed to string interpreting every non zero
value as errors. But these commands display on zero (>0) result.
For example before this commit the display was:

package-1
  die-0
    cpu-14
        get-config-levels:4

Here the get-config-levels is interpreted as error and displayed
as error with the above commit:

package-1
  die-0
    cpu-14
        get-config-levels:failed(error 4)

Fix this issue by not using isst_display_result() to display such results,
but define a new function which formats this data and prints.
