cpufreq: Convert to new X86 CPU match macros

2020-03-24T20:31:27+00:00

The new macro set has a consistent namespace and uses C99 initializers
instead of the grufty C89 ones.

Get rid the of most local macro wrappers for consistency. The ones which
make sense for readability are renamed to X86_MATCH*.

In the centrino driver this also removes the two extra duplicates of family
6 model 13 which have no value at all.

cpufreq: powernow: Don't validate the frequency table twice

2018-03-20T11:07:52+00:00

The cpufreq core is already validating the CPU frequency table after
calling the ->init() callback of the cpufreq drivers and the drivers
don't need to do the same anymore. Though they need to set the
policy->freq_table field directly from the ->init() callback now.

Stop validating the frequency table from powernow driver.

x86/cpu: Rename cpu_data.x86_mask to cpu_data.x86_stepping

2018-02-15T00:15:52+00:00

x86_mask is a confusing name which is hard to associate with the
processor's stepping.

Additionally, correct an indent issue in lib/cpu.c.

I'm leaving Red Hat at the end of December 2014, so remove all
references to my soon-to-be-dead address.

(There are some references left in the tree, that need additional
changes, I'll send those through the AGP maintainers).

cpufreq: powernow-k7: Fix double invocation of cpufreq_freq_transition_begin/end

2014-04-28T23:22:54+00:00

During frequency transitions, the cpufreq core takes the responsibility of
invoking cpufreq_freq_transition_begin() and cpufreq_freq_transition_end()
for those cpufreq drivers that define the ->target_index callback but don't
set the ASYNC_NOTIFICATION flag.

The powernow-k7 cpufreq driver falls under this category, but this driver was
invoking the _begin() and _end() APIs itself around frequency transitions,
which led to double invocation of the _begin() API. The _begin API makes
contending callers wait until the previous invocation is complete. Hence,
the powernow-k7 driver ended up waiting on itself, leading to system hangs
during boot.

Fix this by removing the calls to the _begin() and _end() APIs from the
powernow-k7 driver, since they rightly belong to the cpufreq core.
