cpufreq: amd_freq_sensitivity: Add missing pci_dev_put()

2022-11-30T18:50:04+00:00

pci_get_device() will increase the reference count for the returned pci_dev. We need to use pci_dev_put() to decrease the reference count after using pci_get_device(). Let's add it.

cpufreq: Introducing CPUFREQ_RELATION_E

2021-10-05T14:33:05+00:00

This newly introduced flag can be applied by a governor to a CPUFreq relation, when looking for a frequency within the policy table. The resolution would then only walk through efficient frequencies. Even with the flag set, the policy max limit will still be honoured. If no efficient frequencies can be found within the limits of the policy, an inefficient one would be returned.

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.

x86/devicetable: Move x86 specific macro out of generic code

There is no reason that this gunk is in a generic header file. The wildcard defines need to stay as they are required by file2alias. Signed-off-by: Thomas Gleixner Signed-off-by: Borislav Petkov Reviewed-by: Greg Kroah-Hartman Link: https://lkml.kernel.org/r/20200320131508.736205164@linutronix.de

drivers/cpufreq: Convert some slow-path static_cpu_has() callers to boot_cpu_has()

cpufreq: Add Hygon Dhyana support

2018-09-27T16:29:00+00:00

The Hygon Dhyana CPU supports ACPI P-States, and there is SMBus device (PCI device ID 0x790b) on the Hygon platform. Add Hygon Dhyana support to the cpufreq driver by using the code path of AMD family 17h. Signed-off-by: Pu Wen Signed-off-by: Borislav Petkov Acked-by: Rafael J.
